KEYTRUDA® (pembrolizumab) as Perioperative Treatment With Standard of Care (SOC) Adjuvant Therapy Significantly Improved Event-Free Survival Compared to SOC Alone in Patients With Resectable Locally Advanced Head and Neck Squamous Cell Carcinoma




KEYTRUDA® (pembrolizumab) as Perioperative Treatment With Standard of Care (SOC) Adjuvant Therapy Significantly Improved Event-Free Survival Compared to SOC Alone in Patients With Resectable Locally Advanced Head and Neck Squamous Cell Carcinoma

KEYNOTE-689 marks the first positive trial in more than two decades for patients with resected locally advanced head and neck squamous cell carcinoma (LA-HNSCC)

Results to be presented at American Association for Cancer Research (AACR) Annual Meeting 2025 during a Plenary Session and included in official meeting press program

RAHWAY, N.J.–(BUSINESS WIRE)–$MRK #MRK–Merck (NYSE: MRK), known as MSD outside of the United States and Canada, today announced results from the Phase 3 KEYNOTE-689 trial evaluating KEYTRUDA^® (pembrolizumab), Merck’s anti-PD-1 therapy, as a perioperative treatment regimen for patients with stage III or IVA, resected, locally advanced head and neck squamous cell carcinoma (LA-HNSCC). Results at the first interim analysis of the trial showed KEYTRUDA significantly improved event-free survival (EFS) as part of a perioperative treatment regimen with adjuvant standard of care (SOC) radiotherapy with or without cisplatin compared to adjuvant standard of care (SOC) radiotherapy with or without cisplatin alone in patients with resectable LA-HNSCC. These data are being presented for the first time today during a Plenary Session at the American Association for Cancer Research (AACR) Annual Meeting 2025 (Abstract #CT001) and were selected for the AACR press program.

After a median follow-up of 38.3 months (range, 9.0-66.5), treatment with KEYTRUDA before surgery (neoadjuvant), then continued in combination with standard of care radiotherapy (with or without cisplatin) after surgery followed by KEYTRUDA alone (adjuvant), reduced the risk of EFS events by 34% (HR=0.66 [95% CI, 0.49-0.88]; p=.0022) in the combined positive score (CPS) ≥10 population, by 30% (HR=0.70 [95% CI, 0.55-0.89; p=.0014) in the CPS ≥1 population and by 27% (HR=0.73 [95% CI 0.58-0.92]; p=.0041) in the intent-to-treat (ITT) population, compared to adjuvant radiotherapy (with or without cisplatin) alone in the ITT population. Among the CPS ≥10 population, median EFS was 59.7 months in the KEYTRUDA plus SOC group (95% CI, 41.1-not reached) versus 26.9 months (95% CI, 18.3-51.5) in the SOC group. Among the CPS ≥1 population, median EFS was 59.7 months (95% CI, 37.9-not reached) in the KEYTRUDA plus SOC group versus 29.6 months (95% CI, 19.5-41.9) in the SOC group. In the ITT population, median EFS was 51.8 months (95% CI, 37.5-not reached) in the KEYTRUDA plus SOC group versus 30.4 months (95% CI, 21.8-50.1) in the SOC group. The safety profile of KEYTRUDA was consistent with that observed in previously reported studies; no new safety signals were identified.

“As the first positive trial in over two decades for patients with resectable, locally advanced head and neck squamous cell carcinoma, the presentation of these landmark results marks an important moment for these patients and those who care for them,” said Dr. Ravindra Uppaluri, the study’s co-principal investigator, director of Head and Neck Surgical Oncology, Brigham and Women’s Hospital and Dana-Farber Cancer Institute. “KEYNOTE-689 represents a meaningful development with a potential to provide an option that helps certain patients with LA-HNSCC reduce the risk of recurrence and disease progression earlier in their treatment journey.”

“The addition of immunotherapy using KEYTRUDA to standard of care surgery and adjuvant (chemo)radiotherapy resulted in a significant reduction in the risk of event-free survival events by 27%, compared with standard of care therapy alone,” said study co-principal investigator Dr. Douglas Adkins, Professor, Division of Oncology, Washington University School of Medicine in St. Louis. “These results are notable as they mark the first time an anti-PD-1 therapy has demonstrated a statistically significant and clinically meaningful improvement in event-free survival in the neoadjuvant and adjuvant setting in earlier stages of head and neck squamous cell carcinoma.”

The study also showed a statistically significant improvement in major pathological response (mPR) rate, a key secondary endpoint, in patients with CPS ≥10 (difference in mPR rates: 13.7% [95% CI, 9.7-18.7]; p<0.00001), CPS ≥1 (9.8% [95% CI, 7.0-13.3]; p<0.00001) and in the ITT population (9.3% [95% CI, 6.7–12.8, P<.00001), compared to adjuvant radiotherapy alone.

A trend toward improvement in overall survival (OS), another key secondary endpoint, was observed in patients with CPS ≥10 (HR=0.72 [95% CI, 0.52-0.98]) at the time of this interim analysis for the KEYTRUDA plus standard of care regimen versus standard of care alone. The OS results did not reach statistical significance at the time of this interim analysis. Due to the statistical testing hierarchy, formal testing was not performed in the CPS ≥1 and ITT populations. OS will be evaluated at the next interim analysis.

“As the 12^th positive pivotal trial for a KEYTRUDA-based regimen in earlier-stage cancers, the results from KEYNOTE-689 are a testament to our commitment to address an unmet need in this important area of research,” said Dr. Marjorie Green, senior vice president and head of oncology, global clinical development, Merck Research Laboratories. “These compelling results illustrate the potential of this regimen to change the landscape of care for certain patients facing this challenging disease. We are working with the FDA and other global authorities to bring this new option to patients as quickly as possible.”

A supplemental Biologics License Application (sBLA) for KEYTRUDA based on data from KEYNOTE-689 is under priority review with the U.S. Food and Drug Administration (FDA), with a Prescription Drug User Fee Act (PDUFA), or target action, date of June 23, 2025.

KEYTRUDA is currently approved as monotherapy and in combination regimens for appropriate patients with metastatic or unresectable, recurrent HNSCC in the U.S., Europe, China, Japan and other countries around the world. For more information, please see the “Selected KEYTRUDA^® (pembrolizumab) Indications in the U.S.” section below.

Study design and additional data from KEYNOTE-689

KEYNOTE-689 is a randomized, active-controlled, open-label Phase 3 trial (ClinicalTrials.gov, NCT03765918) evaluating KEYTRUDA as neoadjuvant treatment and KEYTRUDA in combination with standard of care radiotherapy (with or without cisplatin) as adjuvant treatment in treatment-naïve patients with newly diagnosed, stage III or IVA resectable, locally advanced head and neck squamous cell carcinoma (LA-HNSCC). Efficacy outcomes are classified by programmed cell death ligand 1 (PD-L1) combined positive score (CPS) status. The primary endpoint is EFS, which is defined as the time from randomization to the first occurrence of radiographic disease progression; local or distant progression or recurrence; or death due to any cause. The secondary endpoints include OS, mPR, pathological complete response and safety. The study enrolled 714 patients who were randomized 1:1 to receive:

• KEYTRUDA (200 mg intravenously [IV] every three weeks [Q3W] for two cycles) as neoadjuvant therapy prior to surgery, followed by either KEYTRUDA (200 mg IV Q3W for 15 cycles) plus standard of care radiotherapy with cisplatin (100 mg/m² IV Q3W for three cycles) as adjuvant therapy following surgery for high-risk patients or KEYTRUDA (200 mg IV Q3W for 15 cycles) plus standard of care radiotherapy without cisplatin as adjuvant therapy following surgery for low-risk patients; or
• No neoadjuvant therapy prior to surgery, followed by adjuvant standard of care radiotherapy with cisplatin (100 mg/m² IV Q3W for three cycles) as adjuvant therapy following surgery for high-risk patients or standard of care radiotherapy without cisplatin as adjuvant therapy following surgery for low-risk patients.

The safety profile of KEYTRUDA was consistent with that observed in previously reported studies. Grade ≥3 treatment-related adverse events (TRAEs) occurred in 44.6% of patients receiving KEYTRUDA plus standard of care radiotherapy versus 42.9% of patients receiving standard of care radiotherapy alone. TRAEs led to death in 1.1% of patients receiving the KEYTRUDA regimen (n=4) and 0.3% of patients receiving standard of care radiotherapy (n=1). No new safety concerns were identified. Immune-mediated adverse events (AEs) of any grade occurred in 43.2% of patients receiving the KEYTRUDA regimen, most commonly hypothyroidism (24.7%).

About head and neck cancer

Head and neck cancer describes a number of different tumors that develop in or around the throat, larynx, nose, sinuses and mouth. Most head and neck cancers are squamous cell carcinomas that begin in the flat, squamous cells that make up the thin surface layer of the structures in the head and neck. Locally advanced head and neck squamous cell carcinoma (LA-HNSCC) is cancer that has grown outside the original location, but has not yet spread to distant parts of the body. There are several factors that greatly increase the risk of developing head and neck cancer, including tobacco and alcohol use and human papillomavirus (HPV). It is estimated there were more than 947,200 new cases of head and neck cancer diagnosed and over 482,400 deaths from the disease in 2022 globally. In the U.S., it is estimated there will be approximately 72,680 new cases of head and neck cancer diagnosed and more than 16,680 deaths from the disease in 2025.

About Merck’s early-stage cancer clinical program

Finding cancer at an earlier stage may give patients a greater chance of long-term survival. Many cancers are considered most treatable and potentially curable in their earliest stage of disease. Building on the strong understanding of the role of KEYTRUDA in later-stage cancers, Merck is evaluating our portfolio of medicines and pipeline candidates in earlier disease states, with more than 30 ongoing registrational studies across multiple types of cancer.

About KEYTRUDA^® (pembrolizumab) injection, 100 mg

KEYTRUDA is an anti-programmed death receptor-1 (PD-1) therapy that works by increasing the ability of the body’s immune system to help detect and fight tumor cells. KEYTRUDA is a humanized monoclonal antibody that blocks the interaction between PD-1 and its ligands, PD- L1 and PD-L2, thereby activating T lymphocytes which may affect both tumor cells and healthy cells.

Merck has the industry’s largest immuno-oncology clinical research program. There are currently more than 1,600 trials studying KEYTRUDA across a wide variety of cancers and treatment settings. The KEYTRUDA clinical program seeks to understand the role of KEYTRUDA across cancers and the factors that may predict a patient’s likelihood of benefitting from treatment with KEYTRUDA, including exploring several different biomarkers.

Selected Important Safety Information for KEYTRUDA

Severe and Fatal Immune-Mediated Adverse Reactions

KEYTRUDA is a monoclonal antibody that belongs to a class of drugs that bind to either the programmed death receptor-1 (PD-1) or the programmed death ligand 1 (PD-L1), blocking the PD-1/PD-L1 pathway, thereby removing inhibition of the immune response, potentially breaking peripheral tolerance and inducing immune-mediated adverse reactions. Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue, can affect more than one body system simultaneously, and can occur at any time after starting treatment or after discontinuation of treatment. Important immune-mediated adverse reactions listed here may not include all possible severe and fatal immune-mediated adverse reactions.

Monitor patients closely for symptoms and signs that may be clinical manifestations of underlying immune-mediated adverse reactions. Early identification and management are essential to ensure safe use of anti–PD-1/PD-L1 treatments. Evaluate liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment. For patients with TNBC treated with KEYTRUDA in the neoadjuvant setting, monitor blood cortisol at baseline, prior to surgery, and as clinically indicated. In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate.

Withhold or permanently discontinue KEYTRUDA depending on severity of the immune-mediated adverse reaction. In general, if KEYTRUDA requires interruption or discontinuation, administer systemic corticosteroid therapy (1 to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose adverse reactions are not controlled with corticosteroid therapy.

Immune-Mediated Pneumonitis

KEYTRUDA can cause immune-mediated pneumonitis. The incidence is higher in patients who have received prior thoracic radiation. Immune-mediated pneumonitis occurred in 3.4% (94/2799) of patients receiving KEYTRUDA, including fatal (0.1%), Grade 4 (0.3%), Grade 3 (0.9%), and Grade 2 (1.3%) reactions. Systemic corticosteroids were required in 67% (63/94) of patients. Pneumonitis led to permanent discontinuation of KEYTRUDA in 1.3% (36) and withholding in 0.9% (26) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, 23% had recurrence. Pneumonitis resolved in 59% of the 94 patients.

Pneumonitis occurred in 8% (31/389) of adult patients with cHL receiving KEYTRUDA as a single agent, including Grades 3-4 in 2.3% of patients. Patients received high-dose corticosteroids for a median duration of 10 days (range: 2 days to 53 months). Pneumonitis rates were similar in patients with and without prior thoracic radiation. Pneumonitis led to discontinuation of KEYTRUDA in 5.4% (21) of patients. Of the patients who developed pneumonitis, 42% interrupted KEYTRUDA, 68% discontinued KEYTRUDA, and 77% had resolution.

Pneumonitis occurred in 7% (41/580) of adult patients with resected NSCLC who received KEYTRUDA as a single agent for adjuvant treatment of NSCLC, including fatal (0.2%), Grade 4 (0.3%), and Grade 3 (1%) adverse reactions. Patients received high-dose corticosteroids for a median duration of 10 days (range: 1 day to 2.3 months). Pneumonitis led to discontinuation of KEYTRUDA in 26 (4.5%) of patients. Of the patients who developed pneumonitis, 54% interrupted KEYTRUDA, 63% discontinued KEYTRUDA, and 71% had resolution.

Immune-Mediated Colitis

KEYTRUDA can cause immune-mediated colitis, which may present with diarrhea. Cytomegalovirus infection/reactivation has been reported in patients with corticosteroid-refractory immune-mediated colitis. In cases of corticosteroid-refractory colitis, consider repeating infectious workup to exclude alternative etiologies. Immune-mediated colitis occurred in 1.7% (48/2799) of patients receiving KEYTRUDA, including Grade 4 (<0.1%), Grade 3 (1.1%), and Grade 2 (0.4%) reactions. Systemic corticosteroids were required in 69% (33/48); additional immunosuppressant therapy was required in 4.2% of patients. Colitis led to permanent discontinuation of KEYTRUDA in 0.5% (15) and withholding in 0.5% (13) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, 23% had recurrence. Colitis resolved in 85% of the 48 patients.

Hepatotoxicity and Immune-Mediated Hepatitis

KEYTRUDA as a Single Agent

KEYTRUDA can cause immune-mediated hepatitis. Immune-mediated hepatitis occurred in 0.7% (19/2799) of patients receiving KEYTRUDA, including Grade 4 (<0.1%), Grade 3 (0.4%), and Grade 2 (0.1%) reactions. Systemic corticosteroids were required in 68% (13/19) of patients; additional immunosuppressant therapy was required in 11% of patients. Hepatitis led to permanent discontinuation of KEYTRUDA in 0.2% (6) and withholding in 0.3% (9) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, none had recurrence. Hepatitis resolved in 79% of the 19 patients.

KEYTRUDA With Axitinib

KEYTRUDA in combination with axitinib can cause hepatic toxicity. Monitor liver enzymes before initiation of and periodically throughout treatment. Consider monitoring more frequently as compared to when the drugs are administered as single agents. For elevated liver enzymes, interrupt KEYTRUDA and axitinib, and consider administering corticosteroids as needed. With the combination of KEYTRUDA and axitinib, Grades 3 and 4 increased alanine aminotransferase (ALT) (20%) and increased aspartate aminotransferase (AST) (13%) were seen at a higher frequency compared to KEYTRUDA alone. Fifty-nine percent of the patients with increased ALT received systemic corticosteroids. In patients with ALT ≥3 times upper limit of normal (ULN) (Grades 2-4, n=116), ALT resolved to Grades 0-1 in 94%. Among the 92 patients who were rechallenged with either KEYTRUDA (n=3) or axitinib (n=34) administered as a single agent or with both (n=55), recurrence of ALT ≥3 times ULN was observed in 1 patient receiving KEYTRUDA, 16 patients receiving axitinib, and 24 patients receiving both. All patients with a recurrence of ALT ≥3 ULN subsequently recovered from the event.

Immune-Mediated Endocrinopathies

Adrenal Insufficiency

KEYTRUDA can cause primary or secondary adrenal insufficiency. For Grade 2 or higher, initiate symptomatic treatment, including hormone replacement as clinically indicated. Withhold KEYTRUDA depending on severity. Adrenal insufficiency occurred in 0.8% (22/2799) of patients receiving KEYTRUDA, including Grade 4 (<0.1%), Grade 3 (0.3%), and Grade 2 (0.3%) reactions. Systemic corticosteroids were required in 77% (17/22) of patients; of these, the majority remained on systemic corticosteroids. Adrenal insufficiency led to permanent discontinuation of KEYTRUDA in <0.1% (1) and withholding in 0.3% (8) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement.

Hypophysitis

KEYTRUDA can cause immune-mediated hypophysitis. Hypophysitis can present with acute symptoms associated with mass effect such as headache, photophobia, or visual field defects. Hypophysitis can cause hypopituitarism. Initiate hormone replacement as indicated. Withhold or permanently discontinue KEYTRUDA depending on severity. Hypophysitis occurred in 0.6% (17/2799) of patients receiving KEYTRUDA, including Grade 4 (<0.1%), Grade 3 (0.3%), and Grade 2 (0.2%) reactions. Systemic corticosteroids were required in 94% (16/17) of patients; of these, the majority remained on systemic corticosteroids. Hypophysitis led to permanent discontinuation of KEYTRUDA in 0.1% (4) and withholding in 0.3% (7) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement.

Thyroid Disorders

KEYTRUDA can cause immune-mediated thyroid disorders. Thyroiditis can present with or without endocrinopathy. Hypothyroidism can follow hyperthyroidism. Initiate hormone replacement for hypothyroidism or institute medical management of hyperthyroidism as clinically indicated. Withhold or permanently discontinue KEYTRUDA depending on severity. Thyroiditis occurred in 0.6% (16/2799) of patients receiving KEYTRUDA, including Grade 2 (0.3%). None discontinued, but KEYTRUDA was withheld in <0.1% (1) of patients.

Hyperthyroidism occurred in 3.4% (96/2799) of patients receiving KEYTRUDA, including Grade 3 (0.1%) and Grade 2 (0.8%). It led to permanent discontinuation of KEYTRUDA in <0.1% (2) and withholding in 0.3% (7) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement. Hypothyroidism occurred in 8% (237/2799) of patients receiving KEYTRUDA, including Grade 3 (0.1%) and Grade 2 (6.2%). It led to permanent discontinuation of KEYTRUDA in <0.1% (1) and withholding in 0.5% (14) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement. The majority of patients with hypothyroidism required long-term thyroid hormone replacement. The incidence of new or worsening hypothyroidism was higher in 1185 patients with HNSCC, occurring in 16% of patients receiving KEYTRUDA as a single agent or in combination with platinum and FU, including Grade 3 (0.3%) hypothyroidism. The incidence of new or worsening hypothyroidism was higher in 389 adult patients with cHL (17%) receiving KEYTRUDA as a single agent, including Grade 1 (6.2%) and Grade 2 (10.8%) hypothyroidism. The incidence of new or worsening hyperthyroidism was higher in 580 patients with resected NSCLC, occurring in 11% of patients receiving KEYTRUDA as a single agent as adjuvant treatment, including Grade 3 (0.2%) hyperthyroidism. The incidence of new or worsening hypothyroidism was higher in 580 patients with resected NSCLC, occurring in 22% of patients receiving KEYTRUDA as a single agent as adjuvant treatment (KEYNOTE-091), including Grade 3 (0.3%) hypothyroidism.

Type 1 Diabetes Mellitus (DM), Which Can Present With Diabetic Ketoacidosis

Monitor patients for hyperglycemia or other signs and symptoms of diabetes. Initiate treatment with insulin as clinically indicated. Withhold KEYTRUDA depending on severity. Type 1 DM occurred in 0.2% (6/2799) of patients receiving KEYTRUDA. It led to permanent discontinuation in <0.1% (1) and withholding of KEYTRUDA in <0.1% (1) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement.

Immune-Mediated Nephritis With Renal Dysfunction

KEYTRUDA can cause immune-mediated nephritis. Immune-mediated nephritis occurred in 0.3% (9/2799) of patients receiving KEYTRUDA, including Grade 4 (<0.1%), Grade 3 (0.1%), and Grade 2 (0.1%) reactions. Systemic corticosteroids were required in 89% (8/9) of patients. Nephritis led to permanent discontinuation of KEYTRUDA in 0.1% (3) and withholding in 0.1% (3) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, none had recurrence. Nephritis resolved in 56% of the 9 patients.

Immune-Mediated Dermatologic Adverse Reactions

KEYTRUDA can cause immune-mediated rash or dermatitis. Exfoliative dermatitis, including Stevens-Johnson syndrome, drug rash with eosinophilia and systemic symptoms, and toxic epidermal necrolysis, has occurred with anti– PD-1/PD-L1 treatments. Topical emollients and/or topical corticosteroids may be adequate to treat mild to moderate nonexfoliative rashes. Withhold or permanently discontinue KEYTRUDA depending on severity.

UroGen Announces Updated 18-Month Duration of Response (DOR) of 80.6% from the Phase 3 ENVISION Trial of UGN-102, an Investigational Treatment for Recurrent Low-Grade Intermediate-Risk Non-Muscle Invasive Bladder Cancer (LG-IR-NMIBC)




UroGen Announces Updated 18-Month Duration of Response (DOR) of 80.6% from the Phase 3 ENVISION Trial of UGN-102, an Investigational Treatment for Recurrent Low-Grade Intermediate-Risk Non-Muscle Invasive Bladder Cancer (LG-IR-NMIBC)

• 18-month DOR of 80.6% by Kaplan-Meier estimate was attained in patients who achieved a complete response (CR) at three months (79.6%)
• Data unveiled during a Podium Presentation at the American Urological Association (AUA) 2025 Annual Meeting in Las Vegas, Nevada

PRINCETON, N.J.–(BUSINESS WIRE)–UroGen Pharma Ltd. (Nasdaq: URGN), a biotech company dedicated to developing and commercializing innovative solutions that treat urothelial and specialty cancers, today announced an updated 18-month DOR of 80.6% (95% CI: 74.0, 85.7), by Kaplan-Meier estimate, from the Phase 3 ENVISION trial of UGN-102 (mitomycin) for intravesical solution, an investigational treatment for recurrent LG-IR-NMIBC. These data were featured today in an Oral Presentation Session (Abstract ID: PD12) at the AUA 2025 Annual Meeting in Las Vegas, Nevada.

“This new update from the pivotal ENVISION trial of UGN-102 demonstrated a compelling probability of remaining in complete response of 80.6% at 18 months in patients who achieved a complete response (CR) at three months (79.6%),” said Sandip Prasad M.D., M.Phil., Director of Genitourinary Surgical Oncology, Vice Chair of Urology at Morristown Medical Center/Atlantic Health System, NJ, and Principal Investigator of the ENVISION trial. “Low-grade bladder cancer is a persistent cancer that frequently recurs and comes with its own risks. There is a significant unmet need in finding treatment options for patients with recurrent low-grade bladder cancer.”

The existing standard of care for LG-IR-NMIBC is an invasive surgical procedure requiring anesthesia called transurethral resection of bladder tumor (TURBT). Repeated TURBT procedures can impact patients’ physical health and quality of life and are even associated with an increased risk in mortality. Due to high recurrence rates, LG-IR-NMIBC patients, who are typically elderly with comorbidities, will likely need multiple TURBTs under general anesthesia over the course of their lifetime. An estimated 59,000 patients with LG-IR-NMIBC recur annually and face the burden and risks of repeat surgeries that often provide limited value.

Mark Schoenberg, M.D., Chief Medical Officer of UroGen, stated, “The duration of response data from the ENVISION trial further underscores UGN-102’s potential to positively impact the treatment landscape for patients with recurrent LG-IR-NMIBC. Many of these patients are elderly and face the burden of repeated surgeries under general anesthesia, highlighting the urgent need for innovative treatment options. If approved, we believe UGN-102’s potential to deliver durable complete responses, reduce recurrence rates, and extend treatment-free intervals would represent a significant advancement in the management of recurrent LG-IR-NMIBC.”

The most common treatment-emergent adverse events (TEAEs) in the ENVISION trial were dysuria, hematuria, urinary tract infection, pollakiuria, fatigue, and urinary retention. The TEAEs were typically mild-to-moderate in severity and either resolved or were resolving. The ENVISION trial demonstrated a similar safety profile to that observed in other studies of UGN‑102. Median follow-up time at 18 months was 18.7 months after the three-month CR.

UroGen completed the submission of a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for UGN-102 as a treatment for LG-IR-NMIBC ahead of schedule, and the FDA accepted the NDA for UGN-102 with a Prescription Drug User Free Act (PDUFA) goal date of June 13, 2025.

About UGN-102

UGN-102 (mitomycin) for intravesical solution is an innovative drug formulation of mitomycin, currently in Phase 3 development for the treatment of recurrent LG-IR-NMIBC. Utilizing UroGen’s proprietary RTGel^® technology, a sustained release, hydrogel-based formulation, UGN-102 is designed to enable longer exposure of bladder tissue to mitomycin, thereby enabling the treatment of tumors by non-surgical means. UGN-102 is delivered to patients using a standard urinary catheter in an outpatient setting by a trained healthcare professional. UroGen completed the submission of the rolling NDA for UGN-102 in August 2024, ahead of schedule. The FDA accepted the NDA for UGN-102 and assigned a PDUFA goal date of June 13, 2025.

About Non-Muscle Invasive Bladder Cancer (NMIBC)

LG-IR-NMIBC affects around 82,000 people in the U.S. every year and of those, an estimated 59,000 are recurrent. Bladder cancer primarily affects older populations with increased risk of comorbidities, with the median age of diagnosis being 73 years. Guideline recommendations for the management of NMIBC include TURBT as the standard of care. Up to 70 percent of NMIBC patients experience at least one recurrence and LG-IR-NMIBC patients are even more likely to recur and face repeated TURBT procedures.

Pfizer’s Sasanlimab Combination Significantly Improves Event-Free Survival in BCG-Naïve, High-Risk Non-Muscle Invasive Bladder Cancer




Pfizer’s Sasanlimab Combination Significantly Improves Event-Free Survival in BCG-Naïve, High-Risk Non-Muscle Invasive Bladder Cancer

• Pivotal Phase 3 CREST trial results show a 32% reduction in the risk of disease-related events, including high-grade disease recurrence or progression, with sasanlimab in combination with standard of care (SOC) Bacillus Calmette-Guérin (BCG) regimen compared to SOC alone
• Sasanlimab, a subcutaneously administered PD-1 inhibitor, in combination with BCG represents the first potential treatment advancement for BCG-naïve, high-risk non-muscle invasive bladder cancer in more than 30 years
• Results have been shared with global health authorities to support potential regulatory filings

NEW YORK–(BUSINESS WIRE)–Pfizer Inc. (NYSE: PFE) today announced results from the pivotal Phase 3 CREST trial of sasanlimab, an investigational anti-PD-1 monoclonal antibody (mAb), in combination with standard of care (SOC) Bacillus Calmette-Guérin (BCG) as induction therapy with or without maintenance in patients with BCG-naïve, high-risk non-muscle invasive bladder cancer (NMIBC). The trial met its primary endpoint of event-free survival (EFS) by investigator assessment, demonstrating a clinically meaningful and statistically significant improvement with sasanlimab in combination with BCG (induction and maintenance) as compared to BCG alone (induction and maintenance): Hazard Ratio (HR) of 0.68; 95% Confidence Interval (CI), 0.49-0.94; 2-sided p=0.019; median EFS not yet reached. These findings show a 32% reduction in risk of disease-related events, including high-grade disease recurrence or progression, with the sasanlimab combination regimen as compared with SOC treatment alone. Pre-specified subgroup analyses for patients harboring higher risk disease showed consistent benefit with EFS HR of 0.63 (0.41, 0.96) for T1 disease, and EFS HR 0.53 (0.29, 0.98) for those with CIS disease.

EFS was a composite endpoint defined as the time from randomization to the earliest of recurrence of high-grade disease, progression of disease, persistence of carcinoma in situ (CIS), or death due to any cause. The probability of being event-free at 36 months was 82.1% (95% CI, 77.4-85.9) with sasanlimab in combination with BCG (induction and maintenance), and 74.8% (95% CI, 69.7-79.2) with BCG alone (induction and maintenance). Results from the CREST trial are being presented today in a plenary oral presentation at the 2025 American Urological Association (AUA) Annual Meeting.

“New bladder cancer treatment options that help reduce rates of disease recurrence or progression are long overdue. Up to 50% of patients with high-risk non-muscle invasive bladder cancer may experience failure of BCG intravesical immunotherapy, yet it has been the standard of care after tumor resection for decades,” said Neal Shore, M.D., FACS, Medical Director for START Carolina Research Center, and lead investigator for the CREST trial. “These Phase 3 results show that combining sasanlimab with BCG induction and maintenance therapy earlier in the course of the disease significantly prolonged event-free survival, highlighting the value and potential of sasanlimab in combination with BCG to redefine the treatment paradigm and reduce the burden for patients.”

As the ninth most common cancer worldwide, bladder cancer accounts for up to 220,000 deaths annually.^1,2 NMIBC, in particular, represents approximately 75% of all bladder cancer cases.³ In the U.S., it is estimated that about 38,000 people have high-risk NMIBC.⁴ While BCG treatment has been shown to reduce the risk of tumor recurrence, approximately 40-50% of patients with high-risk NMIBC receiving BCG will eventually have disease recurrence or progression despite therapy.^5-7

“Today’s pivotal Phase 3 CREST results offer a much-needed therapeutic breakthrough and spotlight sasanlimab as the first immunotherapy combination with BCG to significantly improve outcomes for patients with BCG-naïve, high-risk NMIBC in over three decades,” said Megan O’Meara, M.D., Interim Chief Development Officer, Pfizer Oncology. “The CREST findings are especially impactful for these patients with early-stage cancer who may benefit the most from innovative treatment regimens, including a subcutaneous immune checkpoint inhibitor, that delay disease recurrence or progression. These results underscore our long-standing commitment to patients with bladder cancer across all stages of the disease. We look forward to working with global regulatory authorities to potentially bring sasanlimab as an important new treatment option to patients with high-risk NMIBC.”

Sasanlimab in combination with BCG (induction only) did not result in prolongation of EFS when compared to BCG alone (induction and maintenance), a key secondary endpoint: HR of 1.16; 95% CI, 0.87-1.55; 2-sided p=0.312, underscoring the need for BCG maintenance not only as a component of SOC treatment but also in combination with sasanlimab. Early interim analysis for the key secondary overall survival (OS) endpoint suggested no difference between treatment arms, with a median follow-up of 40.9 months. The study continues for survival follow-up until the final analysis. Complete response (CR) and duration of CR were additional secondary endpoints for patients with CIS at randomization. The CR rate achieved at any time was 89.8% with sasanlimab in combination with BCG (induction and maintenance) and 85.2% with BCG alone (induction and maintenance). Notably, for those patients with CIS at randomization who achieved a CR, the probability of remaining in CR at 36 months was 91.7% with sasanlimab in combination with BCG (induction and maintenance) compared to 67.7% with BCG alone (induction and maintenance).

The overall safety profile of sasanlimab in combination with BCG was generally consistent with the known profile of BCG and data reported from clinical trials with sasanlimab. The profile of sasanlimab was also generally consistent with the reported safety profile of PD-1 inhibitors. Pfizer has shared these data with global health authorities to support potential regulatory filings.

About CREST

The CREST trial is a Phase 3, multinational, randomized, open-label, three parallel-arm study of sasanlimab, an anti-PD-1 mAb, in combination with BCG (BCG induction with or without BCG maintenance) versus BCG (induction and maintenance) in participants with BCG-naïve, high-risk NMIBC. Patients were randomized to receive sasanlimab 300 mg by subcutaneous (SC) injection every four weeks up to cycle 25 (cycle = four weeks), in combination with BCG once weekly for six consecutive weeks (induction period) followed (Arm A; n=352) or not (Arm B; n=352) by maintenance with BCG, or BCG induction and maintenance up to cycle 25 (Arm C; n=351). The primary endpoint is EFS as assessed by the investigator, between Arm A and C, defined as a composite endpoint that combines time from randomization to the earliest of recurrence of high-grade disease, progression of disease, persistence of CIS, or death. Key secondary endpoints include EFS as assessed by the investigator between Arm B and Arm C, between Arms A/B and Arm C. In patients with CIS, CR and duration of CR were secondary endpoints. For more information on the CREST trial (NCT04165317), go to www.clinicaltrials.gov.

About Sasanlimab

Sasanlimab is a humanized immunoglobulin G4 (IgG4) mAb that binds to human PD-1 to block its interaction with PD-1 and PD-L1/PD-L2. PD-1 is a protein expressed on T cells, dendritic cells, natural killer cells, macrophages, and B cells, that functions as an immune checkpoint that negatively regulates T-cell activation and effector function when activated by its ligands and may play an important role in tumor evasion from host immunity. It can be administered through a once every four weeks SC injection by prefilled syringe (2mL).

In early-stage clinical studies, sasanlimab administered at 300 mg SC every four weeks showed clinical efficacy in advanced solid tumors and advanced urothelial cancer. In addition to NMIBC, sasanlimab is being evaluated in several ongoing clinical trials in combination with Pfizer’s antibody drug conjugate (ADC) portfolio.

UroGen Pharma Announces Encouraging Results from a Phase 1 Dose-Escalation Study Evaluating UGN-301 in Non-Muscle Invasive Bladder Cancer




UroGen Pharma Announces Encouraging Results from a Phase 1 Dose-Escalation Study Evaluating UGN-301 in Non-Muscle Invasive Bladder Cancer

• UGN-301 was tolerated across all dose levels, with no dose-limiting toxicities or adverse events leading to treatment discontinuation
• UGN-301 formulated in a reverse thermal gel allowed sustained exposure in the bladder
• Some patients receiving UGN-301 (zalifrelimab) intravesical solution showed clinical activity at the week 12 disease assessment
• Data presented at the 2025 American Urological Association Annual Meeting in Las Vegas, Nevada

PRINCETON, N.J.–(BUSINESS WIRE)–UroGen Pharma Ltd. (Nasdaq: URGN), a biotech company dedicated to developing and commercializing innovative solutions that treat urothelial and specialty cancers, today announced encouraging safety data from the Phase 1 dose-escalation study for UGN-301 (zalifrelimab) intravesical solution, an investigational drug in development for the treatment of recurrent non-muscle invasive bladder cancer (NMIBC).

“The early safety profile and clinical activity results from this study are encouraging,” said Jay Raman, M.D., Professor and Chair of Urology, and Professor of Surgery, Penn State Cancer Institute, PA. “This innovative approach of localized drug delivery combined with immune modulation merits additional investigation in the treatment of non-muscle invasive bladder cancer.”

The multi-part clinical study included up to 30 patients per arm, aimed to assess safety and determine the recommended Phase 2 dose of UGN-301 as monotherapy and in combination with other agents. In the monotherapy arm, dose escalation continued to the maximum feasible dose. No dose-limiting toxicities and no treatment-emergent adverse events leading to treatment discontinuation were observed. This study also demonstrated that local delivery of UGN-301 formulated in our proprietary reverse thermal gel (RTGel^®) allowed sustained exposure of zalifrelimab in the bladder with limited systemic exposure, which mitigated the risk of systemic immune-related toxicities associated with CTLA-4 inhibition.

With respect to clinical activity observed in the trial, among evaluable patients who received UGN-301, 46% (6 of 13) of those with Ta/T1 disease and 33% (2 of 6) of those with carcinoma in situ (CIS) ± Ta/T1 disease were recurrence-free or had achieved a complete response at week 12. Notably, 60% (3 of 5) of patients with Ta/T1 disease treated with 300 mg continued to remain recurrence-free at the 15-month disease assessment, including one patient with high-grade T1 disease. In the 500 mg cohort, 25% (1 of 4) of patients with CIS disease and 33% (1 of 3) of patients with Ta/T1 disease remained disease-free at six months, both of whom are still active participants in the study.

These findings highlight the potential of UGN-301 as a targeted treatment for NMIBC with an acceptable safety profile. Presentation of data from the combination arms is planned for later this year.

“Our hypothesis is that UGN-301’s unique formulation could potentially offer the dual benefits of maximizing therapeutic activity while minimizing systemic side effects, a key challenge in cancer immunotherapy,” said Mark Schoenberg, Chief Medical Officer, UroGen. “Although this requires additional clinical investigation, we are encouraged by the potential of UGN-301 as an investigational treatment for patients with recurrent NMIBC.”

About Non-Muscle Invasive Bladder Cancer and High-Grade Disease

In the U.S., bladder cancer is the second most common urologic cancer in men. Bladder cancer primarily affects older populations with increased risk of comorbidities, with the median age of diagnosis being 73 years. High-grade non-muscle invasive bladder cancer (HG-NMIBC) is a serious and potentially life-threatening form of bladder cancer that remains confined to the inner layers of the bladder wall but exhibits aggressive behavior and a higher risk of progression. In the U.S., HG-NMIBC accounts for approximately 30–40% of all newly diagnosed NMIBC cases. Patients with HG-NMIBC face a significantly elevated risk of recurrence and progression to muscle-invasive disease, necessitating close surveillance and aggressive treatment. The standard of care includes complete transurethral resection of bladder tumor, often followed by intravesical therapy such as Bacillus Calmette-Guérin (BCG). However, BCG has a treatment failure rate of approximately 40-50%, leaving patients with limited treatment options short of radical cystectomy. Given the high recurrence and progression rates, HG-NMIBC presents a substantial clinical and quality-of-life burden. Upon recurrence, which occurs in approximately 70% of patients, the patients undergo another round of BCG therapy with a response rate of approximately 30%.

About UGN-301

UGN-301 is an anti-CTLA-4 monoclonal antibody (zalifrelimab), originally licensed from Agenus Inc. in 2019. It is formulated with RTGel, our proprietary reverse-thermal hydrogel, for intravesical administration into the bladder. Intravesical administration of UGN-301 is designed to increase drug concentrations in the bladder without significant systemic exposure, potentially diminishing the systemic toxicity associated with CTLA-4 blockade. UroGen is evaluating UGN-301 in a multi-arm Phase 1 study of UGN-301 as monotherapy and in combination with other agents. The safety of UGN-301 is being evaluated in the monotherapy arm of the study as combination therapy for HG-NMIBC.

Veracyte Announces Expanded Availability of Decipher Prostate Test to Patients with Metastatic Prostate Cancer




Veracyte Announces Expanded Availability of Decipher Prostate Test to Patients with Metastatic Prostate Cancer

SOUTH SAN FRANCISCO, Calif.–(BUSINESS WIRE)–$VCYT—Veracyte, Inc. (Nasdaq: VCYT), a leading genomic diagnostics company, today announced the launch of its Decipher Prostate Metastatic Genomic Classifier for use in patients whose prostate cancer has spread beyond the primary tumor. The Decipher Prostate test, already widely used for patients with localized disease, is now the only gene expression test available and covered by Medicare to inform treatment decisions for patients across the full continuum of prostate cancer risk.

Veracyte has begun making the Decipher Prostate Metastatic test available to select clinical sites through an early access program and will begin taking orders for the test more broadly in June 2025.

Prostate cancer is the second-leading cause of cancer deaths among men in the United States and the rate of men diagnosed with advanced disease has been growing in recent years.¹ Veracyte estimates that approximately 10% (or about 30,000) of all prostate cancers diagnosed annually in the United States are metastatic.²

“A number of treatment options are now available to increase survival for patients whose prostate cancer has metastasized,” said Elai Davicioni, Ph.D., Veracyte’s medical director for Urology. “Until now, however, clinicians had limited ways to determine which of these patients will likely benefit from these therapies and which will not and may thus avoid their toxic side effects. We believe the Decipher Prostate Metastatic test will provide an important new tool to help clinicians make more-informed treatment recommendations for their patients with metastatic prostate cancer.”

The Decipher Prostate test’s clinical validity and clinical utility for use in patients with metastatic prostate cancer have been demonstrated in multiple, prospective, Phase 3 clinical studies.^3-6 These studies have shown that such patients with high Decipher scores are likely to have more-aggressive tumor biology compared to those with lower scores, informing the absolute benefit from treatment intensification. These findings build upon extensive data already established for the Decipher Prostate test’s use in patients with localized prostate cancer, where it is the only gene expression test to achieve “Level I” evidence status in the most recent NCCN® Guidelines* for prostate cancer.

“Our expansion into metastatic prostate cancer underscores the power of the Veracyte Diagnostics Platform to uncover novel insights that can enable us to further help patients,” said Philip Febbo, M.D., Veracyte’s chief scientific officer and chief medical officer.

About Decipher Prostate

The Decipher Prostate Genomic Classifier is a 22-gene test, developed using RNA whole-transcriptome analysis and machine learning, that helps inform treatment decisions for patients across the full spectrum of prostate cancer. The test is performed on biopsy or surgically resected samples and conveys the aggressiveness of the cancer. For patients with localized or regional prostate cancer, the Decipher score indicates a patient’s risk of metastasis, helping to determine treatment timing and intensity. For patients with metastatic prostate cancer, the Decipher score indicates the likelihood of cancer progression and survival benefit with treatment intensification. Armed with this information, physicians can better personalize their patients’ care. The Decipher Prostate test’s performance and clinical utility has been demonstrated in over 85 studies involving more than 200,000 patients. It is the only gene expression test to achieve “Level I” evidence status and inclusion in the risk-stratification table in the most recent NCCN® Guidelines* for prostate cancer. More information about the Decipher Prostate test can be found here.

About Veracyte

Veracyte (Nasdaq: VCYT) is a global diagnostics company whose vision is to transform cancer care for patients all over the world. We empower clinicians with the high-value insights they need to guide and assure patients at pivotal moments in the race to diagnose and treat cancer. Our Veracyte Diagnostics Platform delivers high-performing cancer tests that are fueled by broad genomic and clinical data, deep bioinformatic and AI capabilities, and a powerful evidence-generation engine, which ultimately drives durable reimbursement and guideline inclusion for our tests, along with new insights to support continued innovation and pipeline development.

Onc.AI Announces Presentation of Breakthrough-Designated AI Model Evaluated in Clinical Trial Data at AACR 2025




Onc.AI Announces Presentation of Breakthrough-Designated AI Model Evaluated in Clinical Trial Data at AACR 2025

Serial CTRS (CT Response Score) improves prediction of overall survival compared to RECIST 1.1 and Tumor Volume Change in advanced NSCLC

CHICAGO–(BUSINESS WIRE)–Onc.AI, a digital health company developing advanced AI-driven clinical management solutions for oncology, today announced that findings from a recent collaboration with global biopharma company GSK using Onc.AI’s FDA breakthrough-designated Serial CTRS AI model will be presented at the 2025 American Association for Cancer Research (AACR) Annual Meeting. The study externally evaluated Serial CTRS in GSK’s GARNET Phase I clinical trial (NCT02715284) Cohort E, that enrolled patients with advanced non-small cell lung cancer (NSCLC) treated with dostarlimab, GSK’s anti-PD-1 checkpoint inhibitor.

Results, highlighted in a poster presentation during the Predictive Biomarkers 2 session (poster #21, April 27, 2025, 2-5pm), demonstrated that the Serial CTRS biomarker, leveraging routine CT imaging without manual annotations, improved prediction of overall survival (OS) compared to traditional surrogates including RECIST 1.1 response criteria and tumor volume. The analysis was conducted through an independent and blinded retrospective validation study carried out by GSK. In particular, Serial CTRS showed the ability to distinguish patients with intermediate versus high probabilities of 12-month OS (HR: 2.91, 95% CI: 1.16–7.31), outperforming RECIST 1.1 (HR: 1.34, 95% CI: 0.57–3.13) and tumor volume change assessments (HR: 1.00, 95% CI: 0.43–2.34). This enhanced predictive performance supports Onc.AI’s commitment to establishing Serial CTRS as a new standard for automated, AI-based imaging endpoints in the early assessment of treatment response, seamlessly integrating into standard imaging workflows across diverse therapeutic regimens.

Key findings include:

• Serial CTRS improved discrimination between intermediate and high probabilities of overall survival compared to RECIST 1.1 and tumor volume changes.
• Serial CTRS remained a significant predictor of overall survival after adjusting for known prognostic factors, such as age, baseline tumor volume, and PD-L1 Tumor Proportion Score (TPS).

“This important milestone for Serial CTRS builds on a recent breakthrough-designation from FDA,” said Akshay Nanduri, CEO of Onc.AI. “The success of this validation study and ongoing continued collaboration with GSK reflects the strength and robustness of model performance. This can only be achieved using advanced Deep Learning combined with methods for harmonizing diverse imaging data and the breadth of our training data. Onc.AI’s high-quality data on thousands of patients has been sourced from dozens of healthcare systems representing hundreds of clinics across the United States and other international cancer centers, ensuring unparalleled diversity in training, test and validation.”

“As the past head of multiple Phase I clinics at top cancer centers, I believe that Onc.AI’s innovation with Serial CTRS could transform the pharma clinical development process from Phase I to Phase III studies,” said George R. Simon, MD, FACP, FCCP, Vice President of Oncology at OhioHealth.

Iksuda to Present Growing ADC Pipeline at AACR




Iksuda to Present Growing ADC Pipeline at AACR

Introduces the ProAlk payload series to address the growing challenge of ADC sequencing

IKS04 to enter clinical development for gastrointestinal cancers by end of 2025

PermaLink® offers stable and scalable bioconjugation enabling highly stable ADCs

NEWCASTLE, England–(BUSINESS WIRE)–Iksuda Therapeutics (Iksuda), the developer of class leading, clinically validated antibody drug conjugates (ADCs) today announces that it will present three posters at the American Association for Cancer Research (AACR) Annual Meeting in Chicago, Illinois (25-30 April). The posters cover the Company’s new payload class, the ProAlk series, its CA242-directed ADC, IKS04, being developed for the treatment of gastrointestinal (GI) cancers, and its proprietary PermaLink® conjugation chemistry.

Iksuda will introduce its new ProAlk payload class which has a novel protein alkylating mechanism and is incorporated in ADCs in a prodrug format for enhanced targeting precision. ProAlk is active across a broad range of tumours and has been designed for optimal ADC relevance. It is associated with potent bystander activity and is MDR-resistant. Its novel mechanism will help to address the growing and significant challenge of ADC sequencing, where differentiation from tubulin and topoisomerase I inhibitor payloads will become imperative. Iksuda is building a pipeline of ProAlk driven ADCs which incorporate its proprietary PermaLink® conjugation chemistry for ADC stability and tumour-selective payload activation and release for enhanced precision and safety.

The Company will also present a poster on IKS04, its CA242-directed ADC for the treatment of GI cancers and which is in IND-enabling studies. IKS04 uses a pro-drug approach for the tumour-specific delivery of a highly potent pyrrolobenzodiazepine (PBD) payload, avoiding the typical toxicity profile seen in traditional PBD ADCs. In preclinical trials, IKS04 is associated with in vivo efficacy which is substantially improved over benchmark ADCs in all tumour models, and a superior therapeutic index over all other PBD-based solid tumour ADC programs. IKS04 will be administered via pre-administration of naked antibody – a novel dosing regimen in the ADC field – to overcome high expression abundance and enable higher tumour penetration and consistent levels of efficacy across tumours. IKS04 is expected to enter clinical development in GI cancers by the end of 2025.

In addition, Iksuda will highlight its proprietary PermaLink® conjugation chemistry, which is used across its early-stage ADC platform alongside the Company’s glucuronide linker formats and novel ProAlk payload. PermaLink® offers a simple, scalable and highly stable bioconjugation method as an alternative to maleimide-based conjugation, enabling highly stable ADCs with favourable anti-tumour activity and safety.

Dr Dave Simpson, Chief Executive Officer, Iksuda Therapeutics, said:

“These three poster presentations at AACR demonstrate Iksuda’s leadership in ADC innovation as we unveil our novel ProAlk payload class, overcoming the challenges in ADC sequencing and which will drive Iksuda’s deepening pipeline. With two clinical-stage programs, a growing pipeline of class leading ADCs and our expanding, innovative platforms, we are strongly positioned to progress new and promising ADCs to deliver improved outcomes for patients living with cancer. We look forward to progressing IKS04 into clinical development for GI cancers later this year, an area of high unmet need with limited effective treatment options and poor five-year survival rates for the significant number of patients with advanced disease.”

Sensorion Announces Presentation by Pr. Natalie Loundon at the 2025 American Society of Pediatric Otolaryngology Annual Meeting




Sensorion Announces Presentation by Pr. Natalie Loundon at the 2025 American Society of Pediatric Otolaryngology Annual Meeting

MONTPELLIER, France–(BUSINESS WIRE)–Regulatory News:

Sensorion (FR0012596468 – ALSEN) a pioneering clinical-stage biotechnology company specializing in the development of novel therapies to restore, treat and prevent hearing loss disorders, today announced that Pr. Natalie Loundon, pediatric ENT Surgeon, Director of the Center for Research in Pediatric Audiology, Necker Enfants Malades Hospital, AP-HP, in Paris, France, will make an oral presentation at the annual meeting of the American Society of Pediatric Otolaryngology (ASPO).

The Conference is being held in Montreal, Canada, on April 30 – May 3, 2025, and Pr. Loundon’s talk “Principle and Practice of a Gene Therapy for Hearing loss: A Phase 1/2 Clinical Trial with SENS-501 in Children Suffering from Severe to Profound Hearing Loss” will occur on May 1^st at 4.20 pm CET (10.20 am ET).

Pr. Loundon is the Principal Investigator of Audiogene, Sensorion’s Phase 1/2 clinical trial evaluating SENS-501, a gene therapy treatment for DFNB9, a genetic disorder causing severe to profound hearing loss due to mutations in the OTOF gene. Her presentation will include an overview of the rationale behind gene therapy approaches for inner ear hearing loss disorders and the Company’s Audiogene clinical trial.

About the Audiogene Trial

Audiogene aims to evaluate the safety, tolerability and efficacy of intra-cochlear injection of SENS-501 for the treatment of OTOF gene-mediated hearing loss in infants and toddlers aged 6 to 31 months at the time of gene therapy treatment. By targeting the first years of life, when brain plasticity is optimal, the chances of these young children with pre-linguistic hearing loss acquiring normal speech and language are maximized. The study comprises two cohorts of two doses followed by an expansion cohort at the selected dose. While safety will be the primary endpoint of the first part of the dose escalation study, auditory brainstem response (ABR) will be the primary efficacy endpoint of the second part of the expansion. Audiogene will also evaluate the clinical safety, performance and ease-of-use of the delivery system developed by Sensorion.

About Sensorion

Sensorion is a pioneering clinical-stage biotech company, which specializes in the development of novel therapies to restore, treat, and prevent hearing loss disorders, a significant global unmet medical need. Sensorion has built a unique R&D technology platform to expand its understanding of the pathophysiology and etiology of inner ear related diseases, enabling it to select the best targets and mechanisms of action for drug candidates. It has two gene therapy programs aimed at correcting hereditary monogenic forms of deafness, developed in the framework of its broad strategic collaboration focused on the genetics of hearing with the Institut Pasteur. SENS-501 (OTOF-GT) currently being developed in a Phase 1/2 clinical trial, targets deafness caused by mutations of the gene encoding for otoferlin and GJB2-GT targets hearing loss related to mutations in GJB2 gene to potentially address important hearing loss segments in adults and children. The Company is also working on the identification of biomarkers to improve diagnosis of these underserved illnesses. Sensorion’s portfolio also comprises programs of a clinical-stage small molecule, SENS-401 (Arazasetron), for the treatment and prevention of hearing loss disorders. Sensorion’s small molecule progresses in a Phase 2 proof of concept clinical study of SENS-401 in Cisplatin-Induced Ototoxicity (CIO) for the preservation of residual hearing. Sensorion, with partner Cochlear Limited, completed in 2024 a Phase 2a study of SENS-401 for the residual hearing preservation in patients scheduled for cochlear implantation. A Phase 2 study of SENS-401 was also completed in Sudden Sensorineural Hearing Loss (SSNHL) in January 2022.
