Updated results reinforce the potential of TAR-210 to transform treatment of non-muscle-invasive bladder cancer with fibroblast growth factor receptor (FGFR) alterations1
BEERSE, BELGIUM, May 05, 2024 (GLOBE NEWSWIRE) — Janssen-Cilag International NV, a Johnson & Johnson company, announced today updated results from an open-label, multicentre, multi-cohort Phase 1 study of the safety and efficacy of TAR-210, an intravesical targeted releasing system designed to provide sustained, local release of erdafitinib into the bladder, in patients with non-muscle-invasive bladder cancer (NMIBC) with select FGFR alterations.1 These data were featured today in an Oral Presentation Session (Abstract #PD48-02)1 at the 2024 American Urological Association (AUA) Annual Meeting taking place 3-6 May, 2024, in San Antonio, Texas.
Results featured updated data from Cohort 1 (C1); patients with recurrent, Bacillus Calmette-Guérin (BCG)-unresponsive high-risk (HR) NMIBC (high-grade Ta/T1; papillary only) who refused or were ineligible for radical cystectomy and Cohort 3 (C3); patients with recurrent, intermediate-risk (IR) NMIBC (Ta/T1) low-grade papillary disease left in situ as tumour marker lesions.1 First results were featured at the European Society for Medical Oncology 2023 Congress, with interim results presented at the European Association of Urology (EAU) 2024 Annual Congress.2,3
“Advancement in the treatment landscape of high or intermediate-risk non-muscle-invasive bladder cancer has remained stagnant for more than 50 years,” said Antoni Vilaseca*, M.D., Ph.D., of the Hospital Clínic de Barcelona, presenting author of the Phase 1 TAR-210 study. “Results presented today further underscore that TAR-210 for the localised treatment of bladder cancer may offer a promising alternative for patients with limited treatment options.”
At the data cutoff of 22 March, 2024, 64 patients had been treated with TAR-210 across the two cohorts.1 Of the 21 patients in C1 with HR-NMIBC, the 12-month recurrence free (RF) survival rate was 90 percent (95 percent confidence interval (CI), 66-97).1 In C3, 31 patients were efficacy evaluable with 28/31 achieving a complete response (CR) rate of 90 percent (95 percent CI, 74-98).1
The most common treatment-related emergent adverse events (TEAEs) were Grade 1/2 lower urinary tract events.1 There were no dose-limiting toxicities and no deaths.1 Two patients (3 percent) discontinued the study due to TEAEs of low-grade urinary symptoms and two patients had serious TEAEs with pyelonephritis and sepsis or UTI (urinary tract infection) and sepsis, respectively.1
“FGFR genetic alterations are most common in NMIBC,” said Sabine Brookman-May, M.D., Vice President, Late Development Oncology, Johnson & Johnson Innovative Medicine. “These results further support the potential of TAR-210 with quarterly administration as a bladder-sparing and BCG-free treatment option, underscoring our deep commitment to pioneering novel therapies for patients who face limited treatment avenues.”
“At Johnson & Johnson, we are committed to transforming bladder cancer treatment with novel drug delivery technology and precision-based therapies,” said Henar Hevia, Senior Director, EMEA Therapeutic Area Lead, Oncology at Johnson and Johnson Innovative Medicine. “As the data continue to mature, it is encouraging to see sustained positive responses to treatment. We look forward to investigating the full potential of TAR-210 in patients with FGFR-altered non-muscle invasive bladder cancer through an ongoing and comprehensive clinical development programme.”
Europe has one of the highest rates of bladder cancer in the world4 with nearly 225,000 patients diagnosed in 2022,5 a 10 percent increase from 2020.6 NMIBC constitutes approximately 75 percent of all newly diagnosed bladder cancers.7 Currently, adjuvant intravesical immunotherapy with BCG or intravesical chemotherapy is the standard of care for patients with intermediate- and high-risk NMIBC.8 Between 30 to 40 percent of patients do not respond to BCG, facing disease recurrence or progression.9 In such scenarios of HR-NMIBC, radical cystectomy (removal of the bladder) emerges as the primary treatment option.9 This major abdominal procedure requires a urinary diversion to be created to collect and store urine.10
About TAR-210
TAR-210 is an investigational erdafitinib intravesical targeted releasing system.11 The safety and efficacy of TAR-210 is being evaluated in a Phase 1 study (NCT05316155)12 in patients with muscle-invasive bladder cancer (MIBC) and NMIBC. The study categorises patients into four cohorts based on their disease presentation.13 Cohort 1 (C1) includes patients with recurrent, BCG-unresponsive HR-NMIBC with concomitant high-grade papillary disease who have refused or are ineligible for radical cystectomy (RC).13 Cohort 2 (C2) includes patients with the same presentation, but who are scheduled for RC.13 Cohort 3 (C3) includes patients with recurrent, intermediate-risk NMIBC with a history of low-grade papillary disease.13 To be eligible for C3, the presence of visible tumour(s) is required. Cohort 4 (C4) includes patients with MIBC.13 The primary endpoint of the study is safety (adverse events, including dose-limiting toxicity).13 Secondary endpoints include pharmacokinetics (PK), RF survival in patients in C1 and C2, CR rate and duration of CR in patients in C3 and pathologic CR rate in C4.13
About Erdafitinib
Erdafitinib is a once-daily, oral pan-fibroblast growth factor receptor (FGFR) tyrosine kinase inhibitor being evaluated by Johnson & Johnson Innovative Medicine in Phase 2 and 3 clinical trials in patients with advanced urothelial cancer.14 In addition to the Phase 1 study (NCT05316155)12 in patients with MIBC and NMIBC, erdafitinib is also being studied in the Phase 3 THOR study (NCT03390504),15 a study assessing whether erdafitinib provided a survival advantage versus chemotherapy in patients with advanced or metastatic urothelial cancer (mUC) with select FGFR alterations; the Phase 2 THOR-2/BLC2003 (NCT04172675)16 study examining erdafitinib versus investigator choice of intravesical chemotherapy in participants who received BCG and recurred with HR-NMIBC; the Phase 1b/2 NORSE (NCT03473743)17 study of erdafitinib in combination with cetrelimab in patients with locally advanced or mUC and FGFR3 or FGFR2 gene alterations; the Phase 2 RAGNAR (NCT04083976)18 study evaluating the safety and efficacy of erdafitinib in patients with advanced solid tumours, regardless of cancer type or tumour location (tumour-agnostic), driven by FGFR1–4 alterations.
In addition to the marketing authorisation application submitted to the European Medicines Agency (EMA) in September 2023, Johnson & Johnson also submitted a Supplemental New Drug Application to the U.S. Food and Drug Administration (FDA), in August 2023, based upon the Phase 3 THOR study.19,20
In 2008, Janssen Pharmaceuticals entered into an exclusive worldwide licence and collaboration agreement with Astex Pharmaceuticals to develop and commercialise erdafitinib.21
About Urothelial Carcinoma
Urothelial carcinoma (UC), also known as transitional cell carcinoma, starts in the innermost lining of the bladder.22 Almost all bladder cancers – more than 90 percent – are UCs.23 Up to one in five patients (20 percent) diagnosed with mUC have a FGFR genetic alteration.24 FGFRs are a family of receptor tyrosine kinases that can be activated by genetic alterations in a variety of tumour types, and these alterations may lead to increased tumour cell growth and survival.25 FGFRs play a key role in several biological processes including tissue repair, inflammatory response and metabolism.26 Fusions or mutations in the genes that control FGFR (known as FGFR1–4 alterations) may lead to the development and progression of certain cancers by increasing tumour cell growth and survival.27 Patients with advanced UC, including FGFR-driven tumours, face a poor prognosis and the need for innovative therapies remains high.28 The five-year survival rate for patients with metastatic bladder cancer that has spread to distant parts of the body is currently eight percent.29
About High-Risk Non-Muscle-Invasive Bladder Cancer
High-risk non-muscle-invasive bladder cancer (HR-NMIBC) is a type of non-invasive bladder cancer that is more likely to recur or spread beyond the lining of the bladder, called the urothelium, and progress to invasive bladder cancer compared to low-risk NMIBC.30 HR-NMIBC is characterised by a combination of high-grade, large tumour size, presence of multiple tumours, and carcinoma in situ (CIS).30 Radical cystectomy is currently recommended for HR-NMIBC patients who fail BCG therapy, with over 90 percent cancer-specific survival if performed before muscle-invasive progression.30 Given that NMIBC typically affects older patients, many may be unwilling or unfit to undergo radical cystectomy.30 The high rates of recurrence and progression can pose significant morbidity and distress for these patients.30
