Company incubated by Third Rock Ventures with distinguished scientific founders and leading investor syndicate including Sofinnova Investments, Forbion, Perceptive Xontogeny Venture Fund, venBio, Omega Funds, Alpha Wave Global and Surveyor Capital (a Citadel company)

SOUTH SAN FRANCISCO, Calif.–(BUSINESS WIRE)–Marea Therapeutics, a clinical-stage biotechnology company incubated by Third Rock Ventures to develop a new generation of medicines for cardiometabolic diseases, launched today with $190 million in combined Series A and B financings. The Series A round was led by Third Rock Ventures and the Series B round was led by Sofinnova Investments and co-led by Forbion, Perceptive Xontogeny Venture Fund and venBio, with the participation of Alpha Wave Global, Omega Funds, Surveyor Capital (a Citadel company) and founding investor Third Rock Ventures. This financing will fund the company’s MAR001 Phase 2 development plan and further progression of additional pipeline programs.

Marea aims to transform the way cardiometabolic diseases are treated by leveraging large-scale human genetics and expertise in adipose function and biology to pursue genetically validated targets focusing on central – but unaddressed – drivers of cardiometabolic disease risk,” said Josh Lehrer, M.D., M.Phil., FACC, chief executive officer of Marea. “This approach could be the next frontier for patients with cardiometabolic disease who remain at very high risk, despite currently available therapies.”

With initial clinical validation, world-class scientific founders and investors, and an experienced board and leadership team, Marea is poised to become a premier cardiometabolic disease company,” said Jeffrey Tong, Ph.D., board member and partner, Third Rock Ventures. “We aim to accelerate a new generation of medicines, including MAR001, that treat key unaddressed drivers of cardiometabolic disease, potentially providing important new therapeutic options for millions of patients.”

Targeting Cardiometabolic Diseases at their Source

Marea’s lead program, MAR001, is a monoclonal antibody that targets ANGPTL4, a protein that is highly expressed in adipose tissue. By inhibiting ANGPTL4 and thereby preferentially augmenting adipose tissue lipoprotein lipase (LPL) activity, MAR001 aims to lower remnant cholesterol, improve adipose tissue and metabolic function, and reduce cardiovascular events. Remnant cholesterol is carried by triglyceride-rich lipoproteins, is highly atherogenic, and drives cardiovascular events independent of classical risk factors like LDL cholesterol, diabetes or obesity1. There are currently no available targeted therapies to lower remnant cholesterol and improve metabolic function.

Human genetics has demonstrated ANGPTL4 as a highly promising therapeutic target to lower remnant cholesterol with loss of function alleles leading to remnant cholesterol clearance, improved triglyceride distribution, improved insulin sensitivity, and protection from both cardiovascular disease and type 2 diabetes all via an adipose specific mechanism.

Preclinical models with MAR001 demonstrated reduction in triglycerides, remnant cholesterol and ectopic fat (storage of triglycerides in tissues other than adipose tissue), and improved insulin sensitivity. MAR001 has demonstrated strong Phase 1 results and is in Phase 2 clinical development for adults with metabolic dysfunction.

ANGPTL4 human genetics shows the potential to essentially reverse the adipose dysfunction responsible for the metabolic syndrome- which is not adequately treated by current therapies including weight loss and LDL cholesterol treatment. More than five million cardiovascular patients in the U.S. alone have elevated remnant cholesterol putting them at risk for a heart attack,” said Ethan J. Weiss, M.D., co-founder and chief scientific officer of Marea. “MAR001 has the potential to provide unique benefit to these patients by correcting the underlying adipose dysfunction leading to both elevated remnant cholesterol and metabolic dysfunction.”

In a Phase 1 trial, a single dose of MAR001 significantly lowered remnant cholesterol levels and improved metabolic biomarkers. We are very excited about this compound’s potential,” said Maha Katabi, Ph.D., general partner, Sofinnova Investments. “Led by renowned experts in genetics and cardiometabolic diseases, Marea is well positioned to advance MAR001 and other pipeline programs, potentially unlocking a new era in cardiovascular care.”

Marea is also advancing a pipeline of additional candidates aimed to address additional untapped nodes driving cardiometabolic diseases.

Management and Organization

Geron Announces FDA Approval of RYTELO™ (imetelstat), a First-in-Class Telomerase Inhibitor, for the Treatment of Adult Patients with Lower-Risk MDS with Transfusion-Dependent Anemia

  • Approval across ESA ineligible and ESA relapsed/refractory patients with LR-MDS with transfusion-dependent anemia, regardless of ring sideroblast (RS) status
  • Durable and sustained red blood cell transfusion independence, increases in hemoglobin levels and reduction in transfusion burden observed across key LR-MDS subgroups in the IMerge Phase 3 clinical trial; the most common Grade 3/4 adverse reactions were thrombocytopenia and neutropenia, which were generally manageable and short-lived
  • Lower-risk MDS is a progressive blood cancer with high unmet need, where many patients with anemia become dependent on red blood cell transfusions, which can be associated with clinical consequences and decreased quality of life
  • Conference call with Geron management scheduled at 8am ET on Friday, June 7, 2024

FOSTER CITY, Calif.–(BUSINESS WIRE)–Geron Corporation (Nasdaq: GERN), a commercial-stage biopharmaceutical company aiming to change lives by changing the course of blood cancer, today announced that the U.S. Food and Drug Administration (FDA) has approved RYTELO™ (imetelstat) for the treatment of adult patients with low- to intermediate-1 risk myelodysplastic syndromes (MDS) with transfusion-dependent (TD) anemia requiring four or more red blood cell units over eight weeks who have not responded to or have lost response to or are ineligible for erythropoiesis-stimulating agents (ESA).

With the approval and availability of RYTELO, we believe eligible patients with lower-risk MDS can potentially experience meaningful clinical benefit, particularly the potential for greater than 24 weeks of freedom from the burden of red blood cell transfusions and symptomatic anemia,” said John A. Scarlett, M.D., Geron’s Chairman and Chief Executive Officer. “The approval of RYTELO as the first telomerase inhibitor is a testament to the power of our science and the passion of our people to innovate in the field of blood cancer. As we celebrate today’s momentous milestone, I would like to thank the patients and families, advocates, clinicians, study coordinators and site personnel, scientists, and Geron employees and collaborators past and present whose participation was integral to this achievement and to supporting our transformation into a commercial company.”

Lower-risk myelodysplastic syndromes (LR-MDS) is a blood cancer that often progresses to require increasingly intensified management of key symptoms such as anemia and resulting fatigue1. These symptomatic LR-MDS patients frequently become red blood cell transfusion dependent, which has been shown to be associated with short- and long-term clinical consequences that reduce quality of life and shorten survival2,3. There is a high unmet need for many LR-MDS patients, particularly those with characteristics having poorer prognosis. Current treatment options for those failing ESA are limited to select sub-populations and there is an unmet need for treatments that can provide extended and continuous red blood cell transfusion independence.

Approval Based on Results from IMerge Phase 3 Clinical Trial

For patients with lower-risk MDS and anemia who are transfusion dependent, we have very few options today and often cycle through available therapies, making the approval of RYTELO potentially practice changing for us,” said Rami Komrokji, MD, Vice Chair, Malignant Hematology Department, Moffitt Cancer Center, who was an investigator of the pivotal IMerge clinical trial. “What is exciting about RYTELO is the totality of the clinical benefit across LR-MDS patients irrespective of ring sideroblast status or high transfusion burden, including sustained and durable transfusion independence and increases in hemoglobin levels, all within a well-characterized safety profile of generally manageable cytopenias. The treatment goal for patients with LR-MDS and anemia is transfusion-independence and before today, this wasn’t possible for many patients.”

The FDA approval of RYTELO is based on results from the IMerge Phase 3 clinical trial, published in The Lancet4. The IMerge trial met its primary and key secondary endpoints, with RYTELO demonstrating significantly higher rates of red blood cell transfusion independence (RBC-TI) versus placebo for at least eight consecutive weeks (RYTELO 39.8% [95% CI 30.9–49.3]; placebo 15.0% [7.1–26.6]; p<0.001) and for at least 24 weeks (RYTELO 28.0% [95% CI 20.1-37.0]; placebo 3.3% [95% CI 0.4-11.5]; p<0.001). RBC-TI was durable and sustained in the RYTELO treated population, with a median RBC-TI duration for 8-week responders and 24-week responders of approximately 1 year and 1.5 years, respectively.

In an exploratory analysis of RYTELO-treated patients achieving ≥8-week RBC-TI, median increases in hemoglobin were 3.6 g/dL for RYTELO and 0.8 g/dL for placebo. Clinically meaningful efficacy results were observed across key MDS subgroups irrespective of ring sideroblast (RS) status, baseline transfusion burden and IPSS risk category.

In the IMerge trial, the safety profile of RYTELO was well-characterized with generally manageable and short-lived thrombocytopenia and neutropenia, which are familiar side effects for hematologists who are experienced with managing cytopenias. The most common Grade 3/4 adverse reactions were neutropenia (72%) and thrombocytopenia (65%), which lasted a median duration of less than two weeks, and in more than 80% of patients were resolved to Grade < 2 in under four weeks. Cytopenias were generally manageable with dose modifications. The intravenous administration of RYTELO every four weeks aligns to routine blood count monitoring for these patients.

The most common adverse reactions (incidence ≥10% with a difference between arms of >5% compared to placebo), including laboratory abnormalities, were decreased platelets (thrombocytopenia), decreased white blood cells, decreased neutrophils (neutropenia), increased aspartate aminotransferase (AST), increased alkaline phosphatase (ALP), increased alanine aminotransferase (ALT), fatigue, prolonged partial thromboplastin time, arthralgia/myalgia, COVID-19 infections, and headache. Clinically relevant adverse reactions in < 5% of patients who received RYTELO included febrile neutropenia, sepsis, gastrointestinal hemorrhage, and hypertension.

Conference Call Details

A conference call with Geron management is scheduled at 8am Eastern Time on Friday, June 7, 2024, to discuss the FDA approval and launch of RYTELO.

About RYTELO™ (imetelstat)

RYTELO™ (imetelstat) is an FDA-approved oligonucleotide telomerase inhibitor for the treatment of adult patients with low-to-intermediate-1 risk myelodysplastic syndromes (LR-MDS) with transfusion-dependent anemia requiring four or more red blood cell units over eight weeks who have not responded to or have lost response to or are ineligible for erythropoiesis-stimulating agents (ESAs). It is indicated to be administered as an intravenous infusion over two hours every four weeks.

RYTELO is a first-in-class treatment that works by inhibiting telomerase enzymatic activity. Telomeres are protective caps at the end of chromosomes that naturally shorten each time a cell divides. In LR-MDS, abnormal bone marrow cells often express the enzyme telomerase, which rebuilds those telomeres, allowing for uncontrolled cell division. Developed and exclusively owned by Geron, RYTELO is the first and only telomerase inhibitor approved by the U.S. Food and Drug Administration.

Geron aims to ensure broad access to RYTELO for eligible patients. Accordingly, our REACH4RYTELO™ Patient Support Program provides a range of resources that support access and affordability to eligible patients prescribed RYTELO.




RYTELO can cause thrombocytopenia based on laboratory values. In the clinical trial, new or worsening Grade 3 or 4 decreased platelets occurred in 65% of patients with MDS treated with RYTELO.

Monitor patients with thrombocytopenia for bleeding. Monitor complete blood cell counts prior to initiation of RYTELO, weekly for the first two cycles, prior to each cycle thereafter, and as clinically indicated. Administer platelet transfusions as appropriate. Delay the next cycle and resume at the same or reduced dose, or discontinue as recommended.


RYTELO can cause neutropenia based on laboratory values. In the clinical trial, new or worsening Grade 3 or 4 decreased neutrophils occurred in 72% of patients with MDS treated with RYTELO.

Monitor patients with Grade 3 or 4 neutropenia for infections, including sepsis. Monitor complete blood cell counts prior to initiation of RYTELO, weekly for the first two cycles, prior to each cycle thereafter, and as clinically indicated. Administer growth factors and anti-infective therapies for treatment or prophylaxis as appropriate. Delay the next cycle and resume at the same or reduced dose, or discontinue as recommended.

Infusion-Related Reactions

RYTELO can cause infusion-related reactions. In the clinical trial, infusion-related reactions occurred in 8% of patients with MDS treated with RYTELO; Grade 3 or 4 infusion-related reactions occurred in 1.7%, including hypertensive crisis (0.8%). The most common infusion-related reaction was headache (4.2%). Infusion-related reactions usually occur during or shortly after the end of the infusion.

Premedicate patients at least 30 minutes prior to infusion with diphenhydramine and hydrocortisone as recommended and monitor patients for one hour following the infusion as recommended. Manage symptoms of infusion-related reactions with supportive care and infusion interruptions, decrease infusion rate, or permanently discontinue as recommended.

Embryo-Fetal Toxicity

RYTELO can cause embryo-fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with RYTELO and for 1 week after the last dose.


Serious adverse reactions occurred in 32% of patients who received RYTELO. Serious adverse reactions in >2% of patients included sepsis (4.2%) and fracture (3.4%), cardiac failure (2.5%), and hemorrhage (2.5%). Fatal adverse reactions occurred in 0.8% of patients who received RYTELO, including sepsis (0.8%).

Most common adverse reactions (≥10% with a difference between arms of >5% compared to placebo), including laboratory abnormalities, were decreased platelets, decreased white blood cells, decreased neutrophils, increased AST, increased alkaline phosphatase, increased ALT, fatigue, prolonged partial thromboplastin time, arthralgia/myalgia, COVID-19 infections, and headache.

Tiziana Life Sciences Announces Six-Month Qualitative Improvement in Neuroimaging in 80% of Multiple Sclerosis Patients Receiving Intranasal Foralumab

  • Qualitative improvements in PET imaging seen in 80% of non-active Secondary Progressive Multiple Sclerosis (na-SPMS) Expanded Access patients receiving intranasal foralumab for at least 6-months.
  • FDA Allowance for an additional 20 Patients to be enrolled in the intranasal foralumab Multiple Sclerosis Expanded Access Program will allow further data collection and analysis.
  • Applied for FDA Orphan Drug Designation of foralumab for na-SPMS

NEW YORK, June 06, 2024 (GLOBE NEWSWIRE) — Tiziana Life Sciences, Ltd. (Nasdaq: TLSA) (“Tiziana” or the “Company”), a biotechnology company developing breakthrough immunomodulation therapies via novel routes of drug delivery, today announced the qualitative results for all 10 non-active Secondary Progressive Multiple Sclerosis (na-SPMS) patients enrolled in the intermediate-size patient population Expanded Access (EA) Program receiving foralumab for at least six months.

Tarun Singhal, M.B.B.S., M.D., Director of the PET Imaging Program in Neurologic Diseases, associate neurologist and nuclear medicine physician at Brigham and Women’s Hospital, a founding member of Mass General Brigham Healthcare System, and Associate Professor of Neurology at Harvard Medical School, commented, “Based on currently available data from the latest cohort of four Expanded Access patients, three out of the four subjects had findings that suggest a qualitative reduction in the microglial PET signal over a period of six months of treatment with nasal foralumab. When combined with my assessment of the first six Expanded Access patients at six months, eight of the ten suggest a qualitative reduction in microglial PET signal. Further studies are needed to confirm these findings using additional cases and quantitative approaches.”

Gabriele Cerrone, Chairman, acting CEO, and founder of Tiziana Life Sciences, added, “I am thrilled that 80% of the na-SPMS patients who received intranasal foralumab treatment for at least 6-months have a qualitative reduction of microglial activity as confirmed in these latest PET images. I am also greatly appreciative of Dr. Singhal’s research and look forward to the additional quantitative analysis of the data. With the allowance of an additional 20 patients in the EA program, the application for Orphan Drug Designation for na-SPMS, and the ongoing Phase 2a trial, Tiziana is rapidly progressing its intranasal foralumab program in multiple sclerosis.”

About Foralumab

Activated T cells play an important role in the inflammatory process. Foralumab, the only fully human anti-CD3 monoclonal antibody (mAb), binds to the T cell receptor and dampens inflammation by modulating T cell function, thereby suppressing effector features in multiple immune cell subsets. This effect has been demonstrated in patients with COVID and with multiple sclerosis, as well as in healthy normal subjects. The non-active SPMS intranasal foralumab Phase 2 trial (NCT06292923) began screening patients in November of 2023. Immunomodulation by nasal anti-CD3 mAb represents a novel avenue for treatment of neuroinflammatory and neurodegenerative human diseases.[1],[2]

About Tiziana Life Sciences

Tiziana Life Sciences is a clinical-stage biopharmaceutical company developing breakthrough therapies using transformational drug delivery technologies to enable alternative routes of immunotherapy. Tiziana’s innovative nasal approach has the potential to provide an improvement in efficacy as well as safety and tolerability compared to intravenous (IV) delivery. Tiziana’s lead candidate, intranasal foralumab, which is the only fully human anti-CD3 mAb, has demonstrated a favorable safety profile and clinical response in patients in studies to date. Tiziana’s technology for alternative routes of immunotherapy has been patented with several applications pending and is expected to allow for broad pipeline applications.

Osteal Therapeutics Closes $50M Series D Financing to Support Approval and Commercial Launch of Lead Candidate

Financing led by Zimmer Biomet with participation from existing investors Johnson & Johnson Innovation – JJDC, Inc., Gideon Strategic Partners, and HM Capital.

Proceeds will support NDA submission and commercial launch of lead candidate, VT-X7, a 7-day treatment for periprosthetic joint infection.

DALLAS, June 05, 2024 (GLOBE NEWSWIRE) — Osteal Therapeutics, Inc. (“Osteal”), a clinical-stage biopharmaceutical company developing a new category of combination drug/device therapies for orthopedic infections, announced today the completion of an oversubscribed $50 million Series D preferred stock equity financing. Zimmer Biomet led the round, joined by returning investors Johnson & Johnson Innovation – JJDC, Inc., Gideon Strategic Partners, and HM Capital. In conjunction with the financing, a representative of Zimmer Biomet will join Osteal’s Board of Directors.

The proceeds of the financing will be used to advance the development of Osteal’s portfolio of therapies, including the submission of a New Drug Application (NDA) for, and accelerated commercial launch of, VT-X7 for the treatment of periprosthetic joint infection (PJI) of the hip and knee. VT-X7 has been the subject of two multicenter, randomized, controlled trials, APEX and APEX-2. APEX-2 recently met its primary endpoint and will be completed in late 2024. The study builds upon the safety and efficacy evidence obtained from APEX, a similarly designed clinical study that successfully met its primary endpoint in 2023. Both studies were designed in close consultation with the FDA, which previously granted VT-X7 Breakthrough Therapy, Orphan Drug, Fast Track, and Qualified Infectious Disease Product designations. The company expects to seek FDA approval upon completion of APEX-2.

“This round of financing represents an inflection point in the company’s progress towards introducing VT-X7 to the market,” said David Thompson, Chairman and Chief Executive Officer. “From the beginning, Osteal has been extremely fortunate to have the support of a world-class group of financial and strategic partners who share our vision and recognize the tremendous impact our programs will have on patient care. I am delighted to welcome Zimmer Biomet as a partner and look forward to working closely with their exemplary team.”

About Periprosthetic Joint Infection (PJI)

Affecting over 40,000 people in the U.S. annually, PJI is a rare and potentially devastating complication of joint replacement surgery in which pathogenic bacteria colonize the joint prosthesis, forming difficult-to-remove structures called biofilms. Biofilm infections are challenging to resolve, requiring long, invasive and expensive treatments that are often unsuccessful, resulting in high rates of permanent disability and early death. Recent retrospective analyses demonstrate that the current gold standard for treatment of PJI, two-stage exchange arthroplasty, takes an average of 16 weeks and has a success rate under 50% after 12 months, highlighting the unmet need for faster and more efficacious treatment options.

About VT-X7

VT-X7 (vancomycin hydrochloride and tobramycin sulfate for irrigation/VT-X7 irrigation system) is a novel drug/device combination product designed to deliver therapeutic concentrations of vancomycin and tobramycin, well-established, broad-spectrum antibiotics, directly to the joint space and surrounding tissue to treat PJI. VT-X7 is a seven-day therapy designed to address the unmet clinical need for a rapid, reliable treatment for these challenging infections. In clinical studies of VT-X7, 100% of patients were treated and received a new permanent joint prosthesis in seven days with >90% remaining infection-free after one year. The US Food and Drug Administration has granted VT-X7 Breakthrough Therapy, Orphan Drug, Fast Track and Qualified Infectious Disease Product designations. This initial application of VT-X7 represents a first-of-its-kind, multibillion-dollar opportunity to dramatically improve outcomes for a serious unmet medical need.

About Osteal Therapeutics, Inc.

Osteal Therapeutics is a privately held, clinical-stage biopharmaceutical company developing novel musculoskeletal therapeutics to treat orthopedic infections and their consequences. The company is leveraging the ability of concentrated, locally delivered antimicrobials to treat the bacterial biofilms typically responsible for musculoskeletal infections while minimizing off-target tissue exposure and associated adverse effects.

RS Oncology Announces Positive Data from a Phase 1 Clinical Trial of RSO-021, a First-in-Class Therapeutic for Malignant Pleural Mesothelioma

  • First-in-human MITOPE clinical study meets primary objective of Phase 1 safety and tolerability
  • First-in-Class therapy shows early signs of efficacy and offers new hope to patients with malignant pleural mesothelioma with pleural effusion and other cancers.

CAMBRIDGE, Mass.–(BUSINESS WIRE)–#LungcancerRS Oncology, a privately held biopharmaceutical company focusing on novel treatments for rare and aggressive cancers presented positive results from its Phase 1 study in patients with Malignant Pleural Mesothelioma (MPM) with Malignant Pleural Effusion (MPE) or MPE associated with other solid tumors at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting.

The Phase 1 data was presented by Professor Dean Fennell, MRCP, FRCP (MD/PhD) on behalf of all the MITOPE investigators at an oral presentation session. In the 15 recruited patients safety data demonstrated weekly treatment of RSO-021 was well tolerated at 90 mg. The pharmacokinetic data showed minimal systemic exposure to RSO-021 after intrapleural administration. Efficacy data showed a long-term partial response in one patient as well as encouraging survival in 7 of the 10 evaluable patients. In addition to responses in mesothelioma, the drug showed promising responses in non-target lesions and other cancers with metastatic disease to the lung.

“The MITOPE trial would not have been possible without the support of the outstanding investigation teams throughout the UK who are dedicated to the treatment of patients with mesothelioma. We thank all of the MITOPE trial participants and their supportive families, and look forward to hearing about their continued benefit,” said George Naumov, PhD, RS Oncology Chief Operations Officer.

“RSO-021 represents a new class of drugs with a first-in-class anticancer mechanism. The safety and efficacy observed in the Phase 1 trial is supported by strong pre-clinical rationale” said Brian Cunniff, PhD, Chief Science Officer for RS Oncology.

MPM is a rare and aggressive form of cancer that typically develops years after asbestos inhalation and/or exposure. Most cases (70%) originate in the pleura, but it can also be found the peritoneum and the pericardium. A mesothelioma prognosis remains poor with a shorter life expectancy and decreased quality of life.

Phase 2 exploration of this novel agent is ongoing at two doses, as a single agent and in combination with chemotherapy. Clinical trial information: NCT05278975.

Promising Anti-tumor Activity of Novel Costimulatory Bispecific Antibody REGN7075 (EGFRxCD28) in Combination with Libtayo® (cemiplimab) to be Reported at ASCO

Oral presentation to highlight activity of REGN7075 in combination with Libtayo from dose-escalation portion of trial in patients with microsatellite stable colorectal cancer, which has historically proven unresponsive to immunotherapy

Ongoing REGN7075 Phase 1/2 trial is investigating a potentially first-in-class combination across a range of advanced solid tumors

TARRYTOWN, N.Y., May 23, 2024 (GLOBE NEWSWIRE) — Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) today announced positive new results from an ongoing Phase 1/2 trial evaluating its first-in-class costimulatory bispecific antibody, REGN7075 (EGFRxCD28), in combination with Libtayo® (cemiplimab) in patients with advanced solid tumors. Data from the dose-escalation portion of the trial showed the investigational combination led to anti-tumor responses in patients with microsatellite stable colorectal cancer (MSS CRC). REGN7075 is one of the first immunotherapies to demonstrate clinical activity in MSS CRC, including in a patient with liver metastases. The results will be shared during an oral session at the American Society of Clinical Oncology (ASCO) 2024 Annual Meeting in Chicago.

“Microsatellite stable colorectal cancer has historically been unresponsive to immunotherapy,” said Neil H. Segal, M.D., Ph.D., Medical Oncologist and Research Director in the Division of Gastrointestinal Oncology at Memorial Sloan Kettering Cancer Center, and a trial investigator. “The early results for this novel investigational EGFRxCD28 costimulatory bispecific in combination with Libtayo are encouraging, showing anti-tumor responses in a highly difficult-to-treat cancer. This combination is one of the first immunotherapy regimens to show clinical activity in microsatellite stable colorectal cancer, and we are excited to advance this trial in additional tumor types.”

In the dose-escalation portion of the trial, patients with metastatic and locally advanced solid tumors – who had exhausted standard treatment options, and most of whom also had liver metastases – received combination therapy with REGN7075 and Libtayo, following a REGN7075 monotherapy lead-in dose. Among 94 patients treated as of data cutoff, 65% (n=61) had MSS CRC, of which 51 MSS CRC patients were treated at an active dose level. Efficacy results among these 51 patients were as follows:

  • 6% (n=3) overall response rate (ORR) and 29% (n=15) disease control rate (DCR). This included one complete response (CR), two partial responses (PR), and 12 patients with stable disease. At data cutoff, all responders were without liver metastases.
  • Among the subset of 15 patients without liver metastases, there was a 20% ORR (n=3) and 80% DCR (n=12).
  • Among the subset of 36 patients with liver metastases, three patients had stable disease as of data cutoff, and one patient achieved a PR following data cutoff.

Safety was assessed in 84 patients across multiple solid tumor types at a variety of doses of REGN7075. REGN7075 and Libtayo showed an acceptable safety profile, and the maximum tolerated dose was not reached. Treatment-emergent adverse events (TEAEs) of any grade occurred in 98% of patients; Grade 3 and 4 TEAEs occurred in 35% of patients. Treatment-related adverse events (TRAEs) occurred in 90% of patients, with 7% of cases reported as grade 3 or 4. The majority of TRAEs were Grade 1 to 2 (83%), with the most common being infusion-related reactions (58%) that were manageable with premedication and dosing adjustments. TRAEs led to discontinuation in 5% of patients, and three patients discontinued treatment due to Grade 2 infusion-related reactions. As of data cutoff, there have been no dose-limiting toxicities, no reports of cytokine release syndrome, and no treatment-related deaths.

“Regeneron is focused on developing a unique investigational portfolio of oncology medicines including checkpoint inhibitors, CD3 bispecifics and CD28 costimulatory bispecifics. Over the past several years, we have made progress in our programs across checkpoint inhibitors and the CD3 class and are now showing promising activity with two costimulatory bispecific antibodies,” said Israel Lowy, M.D., Ph.D., Senior Vice President, Translational and Clinical Oncology at Regeneron. “Our costimulatory bispecifics were designed with the goal of turning cancer cells into antigen presenting cells, thereby converting historically immunotherapy unresponsive tumors from ‘cold’ to ‘hot’. These early data speak to the potential of REGN7075 in combination with Libtayo and add to a growing body of evidence supporting novel costimulatory bispecifics that are in clinical trials for a range of solid tumors and blood cancers.”

The combination of REGN7075 and Libtayo is currently under clinical development, and its safety and efficacy have not been fully evaluated by any regulatory authority. While the dose escalation portion of the trial across multiple solid tumor types including non-small cell lung cancer, colorectal cancer, head and neck cancer and other tumor types is ongoing, expansion cohorts in several tumor types have also been initiated.

About the Phase 1/2 Trial
The Phase 1/2, first-in-human, open-label trial investigating REGN7075 in combination with Libtayo is currently enrolling patients with metastatic and locally advanced solid tumors who have exhausted standard treatment options. The trial includes an ongoing Phase 1 dose-escalation portion and a Phase 2 dose-expansion period. In the Phase 1 dose-escalation portion, patients first receive a weekly lead-in dose of REGN7075 monotherapy for three weeks to assess its safety and efficacy alone. This is followed by treatment with combination therapy, with Libtayo dosed once every three weeks and REGN7075 dosed either every week or every three weeks. The primary endpoints are assessing safety and tolerability, while the secondary endpoints are assessing efficacy, pharmacokinetics and immunogenicity. Expansion cohorts in several tumor types have been initiated. For more information, visit the Regeneron clinical trials website, or contact via or 844-734-6643.

About Libtayo
Libtayo is a fully human monoclonal antibody targeting the immune checkpoint receptor PD-1 on T cells and was invented using Regeneron’s proprietary VelocImmune® technology. By binding to PD-1, Libtayo has been shown to block cancer cells from using the PD-1 pathway to suppress T-cell activation. In the U.S. and other countries Libtayo is indicated in certain patients with advanced basal cell carcinoma (BCC), advanced cutaneous squamous cell carcinoma (CSCC) and advanced non-small cell lung cancer (NSCLC), as well as in advanced cervical cancer in the European Union, Canada and Brazil. Libtayo is developed and marketed globally by Regeneron.

In the U.S., the generic name for Libtayo in its approved indications is cemiplimab-rwlc, with rwlc as the suffix designated in accordance with Nonproprietary Naming of Biological Products Guidance for Industry issued by the U.S. Food and Drug Administration (FDA). Outside of the U.S., the generic name of Libtayo in its approved indication is cemiplimab.

The extensive clinical program for Libtayo is focused on difficult-to-treat cancers. Libtayo is currently being investigated in trials as a monotherapy, as well as in combination with either conventional or novel therapeutic approaches for other solid tumors and blood cancers. These potential uses are investigational, and their safety and efficacy have not been evaluated by any regulatory authority.

U.S. FDA-approved Indications
Libtayo is a prescription medicine used to treat:

  • People with a type of skin cancer called cutaneous squamous cell carcinoma (CSCC) that has spread or cannot be cured by surgery or radiation.
  • People with a type of skin cancer called basal cell carcinoma (BCC) when your BCC cannot be removed by surgery (locally advanced BCC) or when it has spread (metastatic BCC) and have received treatment with a hedgehog pathway inhibitor (HHI), or cannot receive treatment with a HHI.
  • Adults with a type of lung cancer called non-small cell lung cancer (NSCLC).
    • LIBTAYO may be used in combination with chemotherapy that contains a platinum medicine as your first treatment when your lung cancer has not spread outside your chest (locally advanced lung cancer) and you cannot have surgery or chemotherapy with radiation, or your lung cancer has spread to other areas of your body (metastatic lung cancer), and your tumor does not have an abnormal “EGFR,” “ALK,” or “ROS1” gene.
    • LIBTAYO may be used alone as your first treatment when your lung cancer has not spread outside your chest (locally advanced lung cancer) and you cannot have surgery or chemotherapy with radiation, or your lung cancer has spread to other areas of your body (metastatic lung cancer), and your tumor tests positive for high “PD-L1,” and your tumor does not have an abnormal “EGFR,” “ALK,” or “ROS1” gene.

It is not known if Libtayo is safe and effective in children.


What is the most important information I should know about LIBTAYO?
LIBTAYO is a medicine that may treat certain cancers by working with your immune system. LIBTAYO can cause your immune system to attack normal organs and tissues in any area of your body and can affect the way they work. These problems can sometimes become severe or life-threatening and can lead to death. You can have more than one of these problems at the same time. These problems may happen anytime during treatment or even after your treatment has ended.

Call or see your healthcare provider right away if you develop any new or worsening signs or symptoms, including:

  • Lung problems: cough, shortness of breath, or chest pain
  • Intestinal problems: diarrhea (loose stools) or more frequent bowel movements than usual, stools that are black, tarry, sticky or have blood or mucus, or severe stomach-area (abdomen) pain or tenderness
  • Liver problems: yellowing of your skin or the whites of your eyes, severe nausea or vomiting, pain on the right side of your stomach-area (abdomen), dark urine (tea colored), or bleeding or bruising more easily than normal
  • Hormone gland problems: headache that will not go away or unusual headaches, eye sensitivity to light, eye problems, rapid heartbeat, increased sweating, extreme tiredness, weight gain or weight loss, feeling more hungry or thirsty than usual, urinating more often than usual, hair loss, feeling cold, constipation, your voice gets deeper, dizziness or fainting, or changes in mood or behavior, such as decreased sex drive, irritability, or forgetfulness
  • Kidney problems: decrease in your amount of urine, blood in your urine, swelling of your ankles, or loss of appetite
  • Skin problems: rash, itching, skin blistering or peeling, painful sores or ulcers in mouth or nose, throat, or genital area, fever or flu-like symptoms, or swollen lymph nodes
  • Problems can also happen in other organs and tissues. These are not all of the signs and symptoms of immune system problems that can happen with LIBTAYO. Call or see your healthcare provider right away for any new or worsening signs or symptoms, which may include: chest pain, irregular heartbeat, shortness of breath or swelling of ankles, confusion, sleepiness, memory problems, changes in mood or behavior, stiff neck, balance problems, tingling or numbness of the arms or legs, double vision, blurry vision, sensitivity to light, eye pain, changes in eyesight, persistent or severe muscle pain or weakness, muscle cramps, low red blood cells, or bruising
  • Infusion reactions that can sometimes be severe or life-threatening. Signs and symptoms of infusion reactions may include: nausea, vomiting, chills or shaking, itching or rash, flushing, shortness of breath or wheezing, dizziness, feel like passing out, fever, back or neck pain, or facial swelling
  • Rejection of a transplanted organ. Your healthcare provider should tell you what signs and symptoms you should report and monitor you, depending on the type of organ transplant that you have had
  • Complications, including graft-versus-host disease (GVHD), in people who have received a bone marrow (stem cell) transplant that uses donor stem cells (allogeneic). These complications can be serious and can lead to death. These complications may happen if you underwent transplantation either before or after being treated with LIBTAYO. Your healthcare provider will monitor you for these complications

Getting medical treatment right away may help keep these problems from becoming more serious. Your healthcare provider will check you for these problems during your treatment with LIBTAYO. Your healthcare provider may treat you with corticosteroid or hormone replacement medicines. Your healthcare provider may also need to delay or completely stop treatment with LIBTAYO if you have severe side effects.

Before you receive LIBTAYO, tell your healthcare provider about all your medical conditions, including if you:

  • have immune system problems such as Crohn’s disease, ulcerative colitis, or lupus
  • have received an organ transplant
  • have received or plan to receive a stem cell transplant that uses donor stem cells (allogeneic)
  • have received radiation treatment to your chest area
  • have a condition that affects your nervous system, such as myasthenia gravis or Guillain-Barré syndrome
  • are pregnant or plan to become pregnant. LIBTAYO can harm your unborn baby
  • are breastfeeding or plan to breastfeed. It is not known if LIBTAYO passes into your breast milk. Do not breastfeed during treatment and for at least 4 months after the last dose of LIBTAYO

Females who are able to become pregnant:

  • Your healthcare provider will give you a pregnancy test before you start treatment
  • You should use an effective method of birth control during your treatment and for at least 4 months after your last dose of LIBTAYO. Talk to your healthcare provider about birth control methods that you can use during this time
  • Tell your healthcare provider right away if you become pregnant or think you may be pregnant during treatment with LIBTAYO

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.

The most common side effects of LIBTAYO when used alone include tiredness, muscle or bone pain, rash, diarrhea, and low levels of red blood cells (anemia). The most common side effects of LIBTAYO when used in combination with platinum-containing chemotherapy include hair loss, muscle or bone pain, nausea, tiredness, numbness, pain, tingling, or burning in your hands or feet, and decreased appetite. These are not all the possible side effects of LIBTAYO. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

iCell Gene Therapeutics Announces Positive Clinical Data from Investigator Initiated Phase 1 Trial Evaluating BCMA-CD19 Compound CAR in Patients with Systemic Lupus Erythematosus/Lupus Nephritis Published in Annals of the Rheumatic Diseases

BCMA-CD19 compound CAR (cCAR) therapy was safe and well tolerated and achieved proof of concept of complete humoral reset delivering long-term medication-free remission –

iCell’s BCMA-CD19 cCAR was the first CAR T evaluated in autoimmune disease with first SLE patient treated September 2019

Based on successful IIT study, iCell plans to file INDs in U.S. and China

STONY BROOK, N.Y.–(BUSINESS WIRE)–iCell Gene Therapeutics, a clinical stage biopharmaceutical company focused on immunotherapies for autoimmune disorders and cancer, today announced the publication in Annals of the Rheumatic Diseases of positive results of an investigator initiated clinical trial (IIT) for its BCMA-CD19 compound chimeric antigen receptor (cCAR) T cell immunotherapy.

The clinical trial evaluated the safety and efficacy of a complete humoral reset of both long-lived plasma cells and B cells in 13 systemic lupus erythematosus (SLE) patients treated with iCell’s cCAR, including 11 patients with SLE and lupus nephritis (LN). All patients (12/13) who received an initial dose of 3×106 cCAR cells/kg were negative for all autoantibodies, including those derived from long-lived plasma cells, 3-months post-cCAR, and the complement returned to normal levels. These patients achieved symptom-free and medication-free remission (MFR), with post-cCAR follow-up to 46 months. cCAR therapy was well tolerated with mild cytokine-release syndrome (no CRS >1). iCell considers this IIT to be a successful proof of concept; the Company plans to file an investigational new drug application (IND) for its BCMA-CD19 cCAR in the United States and China.

iCell’s cCAR, with two independently functioning CARs in a single construct targeting the B cell CD19 and the plasma cell BCMA surface antigens, is uniquely designed to completely reset humoral immunity and address the underlying cause of SLE/LN through the elimination of all elevated autoantibodies including those produced by long-lived plasma cells.

Unique armoring of iCell’s cCAR allows for safe pretreatment conditioning with cyclophosphamide only (no fludarabine was used in LN patients), and patients in the study discontinued all lupus medications, including glucocorticoids and immunosuppressants, prior to cCAR treatment and remained lupus medication-free post-infusion. There are currently no approved therapies that deliver MFR in SLE/LN patients who are at high risk of long-term organ damage and kidney transplant.

“This study demonstrates that the complete reset of humoral immunity results in elimination of all elevated autoantibodies, that long term medication free remission is achievable, and that treatment with a BCMA-CD19 compound CAR is well-tolerated in patients suffering from lupus nephritis. The data show humoral immunity recovering, a low rate of infections, no CRS greater than 1, and no ICANS observed to date,” said Yupo Ma, M.D., Ph.D., Chief Scientific Officer and Founder of iCell. “iCell now has the largest clinical dataset of autoimmune patients receiving CAR therapy, and we are excited to continue the advancement of our BCMA-CD19 cCAR.”

“iCell first envisioned the potential for CAR treatments in autoimmune diseases more than 10 years ago and subsequently became the first to patent a BCMA-CD19 compound CAR. Nearly five years ago, we were the first company worldwide to treat an autoimmune patient with a CAR, and we are delighted to see that this patient continues to do well,” said Greg Deener, Chief Executive Officer of iCell. “We look forward to receiving further follow up data confirming the promising results to date, and we plan to present this data on June 12th at the European Alliance of Associations for Rheumatology (EULAR) 2024 Congress.”

Study Details:

iCell designed its cCAR T Cell immunotherapy to express two distinct and fully functional CAR molecules in a single construct, one that targets the molecule CD19 present on B cells and one that targets BCMA present on plasma cells. Targeting both B cells and long-lived plasma cells is needed to eliminate all elevated autoantibodies, given they have separate and redundant memory. iCell’s cCAR is armored to safely promote T cell survival and function and to allow for cyclophosphamide-only conditioning.

The single arm IIT evaluating iCell’s BCMA-CD19 cCAR was conducted in two leading centers in China, Zhongshan People’s Hospital and Peking University Shenzhen Hospital. Initially two patients with SLE and comorbid localized lymphoma were treated with the BCMA-CD19 cCAR (the first in September 2019); 11 patients with LN with biopsy-confirmed active disease (Class III-V) and inadequate response to at least two lines of therapies were subsequently enrolled into the study and treated between June 2022 and February 2023. Ten LN patients received the target single cCAR dose of 3×106/kg.

Overall, the cCAR therapy was found to be generally safe and well-tolerated. The 10 LN patients receiving the target dose achieved depletion of B cells from peripheral blood within 10 days post-cCAR treatment and depletion of immunoglobulin within 42 days, and complete recovery of B cells and IgM was seen within 2-6 months post-cCAR. Excluding COVID-19, the only infection reported was a grade 1 urinary tract infection. In iCell’s overall cCAR safety database of 18 patients with autoimmune diseases (including the 13 patients with SLE or LN), there have been no CRS >1 and no ICANS or CRES.

All lupus patients (12/13) who received the target dose were negative for all autoantibodies, including those derived from long-lived plasma cells, 3-months post-cCAR, and the complement returned to normal levels. Patients achieved symptom-free and medication-free remission (MFR), with post-cCAR follow-up to 46-months. Mean Systemic Lupus Erythematosus SLE Disease Activity Index 2000 (SLEDAI-2K) reduced from 9.9 (baseline) to 2.3 (3 months), and mean renal function significantly improved in the 10 LN patients ≤90 days post-cCAR. The data suggest that cCAR therapy was safe and effective in inducing MFR and depleting disease-causing autoantibodies in SLE and LN patients.

About SLE/LN

Systemic lupus erythematosus is an antibody-mediated autoimmune disease, in which autoantibodies attack the body’s own tissues, resulting in widespread damage in affected organs including kidneys, lungs, joints, brain and blood vessels. According to the Lupus Foundation of America, an estimated 1.5 million Americans, and at least five million people worldwide, have SLE/LN. Lupus nephritis affects ~40% of SLE patients and disproportionately burdens nonwhite women from lower socioeconomic groups. LN patients have a 6-fold higher risk of mortality with 1 in 4 progressing to end stage renal disease There are currently no treatments targeting the underlying causes of the disease delivering MFR. Standard of care LN treatments have substantial side effects. Prolonged immunosuppression increases the risk of serious infections and cancers. Glucocorticoid associated adverse effects include osteoporotic fractures, avascular necrosis, diabetes mellitus, cataracts, glaucoma, and premature mortality.

Cimeio Therapeutics : CD45 ADC and Shielded HSCs Represent a Potentially Universal Therapy for Blood Cancers

— Selective and complete eradication of leukemic cells with an ADC targeting the pan-blood marker CD45 —

— Engineered hematopoietic Stem Cells (HSCs) shielded from the CD45-targeting ADC maintain full functionality —

— Represents a novel, potentially universal approach to treating blood cancers —

BASEL, Switzerland & CAMBRIDGE, Mass.–(BUSINESS WIRE)–Cimeio Therapeutics today announced a publication in Nature showing that its CD45 antibody-drug conjugate (ADC) eradicated aggressive leukemic cells in vivo, while hematopoiesis was fully preserved and protected from the ADC via shielded hematopoietic stem cells (HSCs). The findings point to a novel and potentially universal approach to treating blood cancers.

CD45 is highly expressed on blood cancers but also on healthy blood cells. This profile until now has prevented effective targeting for therapeutic purposes. Now, a group led by Dr. Lukas Jeker, and researchers at Cimeio have shown that acute myeloid leukemia (AML) cells can be eliminated using Cimeio’s proprietary CD45-targeting ADC. By transplanting engineered HSCs that are shielded from the CD45-directed therapy, the CD45 ADC was safely and effectively administered against the blood cancers.

This work is foundational for the emerging field called epitope shielding, which enables the development of curative therapies for patients with hematologic diseases, severe autoimmune conditions and potentially infectious diseases such as HIV. The core patent for epitope shielding is exclusively licensed to Cimeio by University of Basel.

“All AML cells express CD45 but since all healthy blood cells also express it, killing cells that express CD45 results in severe toxicity,” said Dr. Jeker, who is the co-founder of Cimeio and Professor of Experimental Transplantation Immunology & Nephrology at the Basel University Hospital, Switzerland. “We solved the problem by providing epitope-shielded HSCs, which enable the ADC to selectively deplete cancer cells while sparing the healthy ones.”

“We believe that this therapy could change the treatment paradigm for patients with AML, which is a difficult-to-treat disease with a five-year survival rate of only 25%,” said Stefanie Urlinger, Ph.D., Chief Scientific Officer at Cimeio. “By protecting a patient’s heme system from toxicity, we are able to develop new targeted treatments previously not possible.”

Cimeio Therapeutics is developing epitope engineered cells and paired targeted therapies for CD45 and CD117, and epitope engineered cells for CD33, CD52, and several other heme targets.

About Cimeio Therapeutics

Cimeio is an immunotherapy company developing Shielded-Cell & Immunotherapy Pairs™ (SCIP), novel immunotherapies which have the potential to transform treatment of hematologic diseases. Cimeio develops immunotherapies, along with paired, modified variants of naturally occurring cell surface proteins in HSCs. These novel epitopes edited variants maintain their function but are resistant to depletion when targeted by a paired immunotherapy which has high affinity for the wild-type version of these proteins. These immunotherapies have significant therapeutic potential, which Cimeio is using to develop curative treatments for patients with hematologic malignancies, autoimmune disorders, and genetic diseases.

AmorChem’s RNA Zipcode Delivery Technology Investment Exits via New York-Based Kodikaz Therapeutic Solutions, Inc.

MONTREAL–(BUSINESS WIRE)–AmorChem II Fund L.P. (”AmorChem”) is delighted to announce that its RNA Zipcode delivery program has been acquired by Kodikaz Therapeutic Solutions, Inc. (”Kodikaz”), a New York City biotech focused on targeted delivery of cancer therapeutics. The RNA Zipcode program was the first university-based investment of AmorChem’s second fund and was developed by Professors Eric Lécuyer (Montreal Clinical Research Institute), Mathieu Blanchette (McGill University), and Jérôme Waldispühl (McGill University).

”We invested in this technology ahead of current trends and prior to the pandemic of 2020, when the promise of RNA-based therapeutics was crystallized in an effort that saved millions of lives. Focus on RNA-based therapeutics has grown steadily since, though one of the major issues remains delivery – not only to the appropriate tissue – but also to the correct subcellular localization. The work of Kodikaz on targeted delivery of therapeutics to cancer cells using their DNA zipcode technology made them a most attractive receptor for our assets, and in fact, both groups saw synergy in combining the two approaches. It’s truly exciting to see our RNA Zipcode program now move forward in collaboration between the researchers and the Kodikaz group, which includes a seasoned management team already in place,” says Kevin McBride, General Partner & CSO at AmorChem.

”The success of our RNA Zipcode program highlights our specialized investment strategy: digging deep into Quebec academia searching for novel therapeutic approaches that will benefit patients. This often means that AmorChem bets on nascent technologies that have not yet been proven. In the RNA Zipcode case, our team spearheaded the collaboration between three teams from two major research institutions and AmorChem’s investment leveraged additional financial support from several granting agencies. Our mobilization of the appropriate human and financial resources allowed us to attract a valuable partner. This is now bringing a transformative academic technology one step closer to patients while building Kodikaz’s pipeline to a full suite of complementary delivery tools,” comments Inès Holzbaur, Managing Partner at AmorChem.

”This is a great opportunity to partner with world-renowned inventors that bring expertise in artificial intelligence and RNA delivery. We are excited to bring in the new capability that permits us to further control delivery not only to the targeted cell but also within the cell with high specificity,” says Anthony Johnson, Kodikaz President & CEO.

The transaction was made possible by the great collaboration of Axelys and McGill University’s Office of Innovation + Partnerships. The RNA Zipcode program was generously supported by grants from the Genomic Applications Partnership Program (Genome Canada and Genome Quebec), as well as the Programme de soutien aux organismes de recherche et d’innovation (Ministère de l’Économie, de l’Innovation et de l’Énergie) and Médicament Québec.
