"Patients with follicular lymphoma are likely to face disease recurrence and shorter durability of response with each subsequent line of treatment. This positive opinion recognizes the unmet need in the European Union for individuals with relapsed or refractory follicular lymphoma, following failure of other therapies," said Mariana Cota Stirner, M.D., Ph.D., vice president, therapeutic area head for hematology, AbbVie.

FL is typically an indolent (or slow-growing) form of non-Hodgkin’s lymphoma (NHL) that arises from B-lymphocytes and is the second most common form of NHL accounting for 20-30% of all cases.1 In 2023, there were an estimated 13,000 cases of FL in Western Europe.2 FL is considered incurable with current standard of care therapies.3

The CHMP opinion is supported by overall and complete response data from the Phase 1/2 EPCORE NHL-1 clinical trial in 128 patients with R/R FL treated with epcoritamab after two or more lines of prior therapy. The study included patients who were refractory to both anti-CD20 monoclonal antibody therapy and an alkylating agent, patients who were refractory to last prior treatment, and patients whose disease progressed within two years of first systemic therapy. The safety profile of epcoritamab in the pivotal cohort was similar to reports of epcoritamab monotherapy in the pivotal EPCORE NHL-1 diffuse large B-cell lymphoma (DLBCL) cohort.4

An additional cohort of 86 patients evaluated a 3-step-up dosing (SUD) schedule to reduce the incidence and severity of cytokine release syndrome (CRS), which is an associated adverse effect from immune-engaging cancer treatments. For the first full dose of this 3-step regimen, mandatory hospitalization was not required. In this cohort, the incidence of CRS was 49% (42 of 86 patients; 9% were grade 2). There were no grade 3 or higher CRS events. The data from this optimization cohort of the EPCORE NHL-1 study were recently published in the Lancet Haematology.

"Each year, thousands of people in Europe are diagnosed with follicular lymphoma, and it’s an upsetting reality that many of them will experience relapse and refractory disease," said Catherine Thieblemont, M.D., Ph.D., head of the hemato-oncology department, Paris University, Hôpital Saint-Louis Assistance-Publique-Hopitaux de Paris (APHP) in Paris. "Patients deserve new treatment options, and this positive opinion is the first step to bringing epcoritamab to more patients who need it."

Epcoritamab is being co-developed by AbbVie and Genmab as part of the companies’ oncology collaboration. The companies will share commercial responsibilities in the U.S. and Japan, with AbbVie responsible for further global commercialization. Both companies will pursue additional international regulatory approvals for the investigational R/R FL indication and additional approvals for the R/R DLBCL indication.

About the Phase 1/2 EPCORE NHL-1 Trial
EPCORE NHL-1 is an open-label, multi-center safety and preliminary efficacy trial of epcoritamab that consists of three parts: a dose escalation part; an expansion part; and an optimization part. The trial was designed to evaluate subcutaneous epcoritamab in patients with relapsed, progressive or refractory CD20+ mature B-cell non-Hodgkin’s lymphoma (B-NHL), including FL. In the expansion part, additional patients were enrolled to further explore the safety and efficacy of epcoritamab in three cohorts of patients with different types of relapsed/refractory B-NHLs who have limited therapeutic options. The optimization part evaluates the potential for alternative step-up dosing regimens to help further minimize Grade 2 cytokine release syndrome (CRS) and mitigate Grade ≥3 CRS. The primary endpoint of the expansion part was ORR as assessed by an IRC. Secondary efficacy endpoints included duration of response, complete response rate, duration of complete response, progression-free survival, and time to response as determined by the Lugano criteria. Overall survival, time to next therapy, and rate of minimal residual disease negativity were also evaluated as secondary efficacy endpoints. The primary endpoint of the optimization part was the rate of ≥ Grade 2 CRS events and all grade CRS events from first dose of epcoritamab through 7 days following administration of the second full dose of epcoritamab.

Topline results of the study were shared in December 2023. More information can be found on www.clinicaltrials.gov (NCT03625037).

About Follicular Lymphoma (FL)
FL is typically an indolent (or slow-growing) form of non-Hodgkin’s lymphoma (NHL) that arises from B-lymphocytes and is the second most common form of NHL accounting for 20-30% of all cases.1 FL is considered incurable with current standard of care therapies.3 Patients often relapse and with each relapse, the remission and time to next treatment is shorter.5 Over time, transformation to DLBCL, an aggressive form of NHL associated with poor survival outcomes, can occur in more than 25% of FL patients.6

About Epcoritamab
Epcoritamab is an investigational IgG1-bispecific antibody created using Genmab’s proprietary DuoBody technology and administered subcutaneously. Genmab’s DuoBody-CD3 technology is designed to direct cytotoxic T cells selectively to elicit an immune response toward target cell types. Epcoritamab is designed to simultaneously bind to CD3 on T cells and CD20 on B cells and induces T-cell-mediated killing of CD20+ cells.7

Epcoritamab (approved under the brand name EPKINLY in the United States and TEPKINLY in the European Union) has received regulatory approval in certain lymphoma indications in several countries.

AbbVie will continue to pursue regulatory submissions for epcoritamab across international markets. Both Genmab and AbbVie continue to evaluate the use of epcoritamab as a monotherapy and in combination across lines of therapy in a range of hematologic malignancies. Please visit clinicaltrials.gov for more information.

EU Indications and Important Safety Information about Tepkinly▼(epcoritamab)

Indications
Tepkinly (epcoritamab) as monotherapy is indicated for the treatment of adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) after two or more lines of systemic therapy.

Important Safety Information

Contraindications
Hypersensitivity to the active substance or to any of the excipients.

Special warnings and precautions for use
Cytokine release syndrome (CRS)
CRS, which may be life-threatening or fatal, occurred in patients receiving Tepkinly. The most common signs and symptoms of CRS include pyrexia, hypotension and hypoxia. Other signs and symptoms of CRS in more than two patients include chills, tachycardia, headache and dyspnoea.

Most CRS events occurred in Cycle 1 and were associated with the first full dose of Tepkinly. Administer prophylactic corticosteroids to mitigate the risk of CRS. Patients should be monitored for signs and symptoms of CRS following Tepkinly administration. Patients should be hospitalised for 24 hours after administration of the Cycle 1 Day 15 dose of 48 mg to monitor for signs and symptoms of CRS. At the first signs or symptoms of CRS, institute treatment of supportive care with tocilizumab and/or corticosteroids as appropriate. Patients should be counselled on the signs and symptoms associated with CRS and patients should be instructed to contact their healthcare professional and seek immediate medical attention should signs or symptoms occur at any time. Management of CRS may require either temporary delay or discontinuation of Tepkinly based on the severity of CRS.

Immune effector cell-associated neurotoxicity syndrome (ICANS)
ICANS, including a fatal event, have occurred in patients receiving Tepkinly. ICANS may manifest as aphasia, altered level of consciousness, impairment of cognitive skills, motor weakness, seizures, and cerebral oedema. The majority of cases of ICANS occurred within Cycle 1 of Tepkinly treatment, however some occurred with delayed onset. Patients should be monitored for signs and symptoms of ICANS following Tepkinly administration. Patients should be hospitalised for 24 hours after administration of the Cycle 1 Day 15 dose of 48 mg to monitor for signs and symptoms of ICANS. At the first signs or symptoms of ICANS treatment with corticosteroids and non-sedating-anti-seizure medicinal products should be instituted as appropriate. Patients should be counselled on the signs and symptoms of ICANS and that the onset of events may be delayed. Patients should be instructed to contact their healthcare professional and seek immediate medical attention should signs or symptoms occur at any time. Tepkinly should be delayed or discontinued as recommended.

Serious infections
Treatment with Tepkinly may lead to an increased risk of infections. Serious or fatal infections were observed in patients treated with Tepkinly in clinical studies. Administration of Tepkinly should be avoided in patients with clinically significant active systemic infections. As appropriate, prophylactic antimicrobials should be administered prior to and during treatment with Tepkinly. Patients should be monitored for signs and symptoms of infection, before and after Tepkinly administration, and treated appropriately. In the event of febrile neutropenia, patients should be evaluated for infection and managed with antibiotics, fluids and other supportive care, according to local guidelines.

Tumour Lysis Syndrome (TLS)
TLS has been reported in patients receiving Tepkinly. Patients at an increased risk for TLS are recommended to receive hydration and prophylactic treatment with a uric acid lowering agent. Patients should be monitored for signs or symptoms of TLS, especially patients with high tumour burden or rapidly proliferative tumours, and patients with reduced renal function. Patients should be monitored for blood chemistries and abnormalities should be managed promptly.

Tumour flare
Tumour flare has been reported in patients treated with Tepkinly. Manifestations could include localized pain and swelling. Consistent with the mechanism of action of Tepkinly, tumour flare is likely due to the influx of T-cells into tumour sites following Tepkinly administration. There are no specific risk factors for tumour flare that have been identified; however, there is a heightened risk of compromise and morbidity due to mass effect secondary to tumour flare in patients with bulky tumours located in close proximity to airways and/or a vital organ. Patients treated with Tepkinly should be monitored and evaluated for tumour flare at critical anatomical sites.

CD20-negative disease
There are limited data available on patients with CD20-negative DLBCL treated with Tepkinly, and it is possible that patients with CD20-negative DLBCL may have less benefit compared to patients with CD20- positive DLBCL. The potential risks and benefits associated with treatment of patients with CD20- negative DLBCL with Tepkinly should be considered.

Immunisation
Live and/or live-attenuated vaccines should not be given during Tepkinly therapy. Studies have not been conducted in patients who received live vaccines.

Fertility, pregnancy and lactation
Tepkinly is not recommended during pregnancy and in women of childbearing potential not using contraception.

Effects on ability to drive and use machines
Tepkinly has minor influence on the ability to drive and use machines. Due to the potential for ICANS, patients should be advised to exercise caution while (or avoid if symptomatic) driving, cycling or using heavy or potentially dangerous machines.

Undesirable effects
Summary of the safety profile
The most common adverse reactions (≥ 20%) were CRS, fatigue, neutropenia, injection site reactions, musculoskeletal pain, abdominal pain, pyrexia, nausea, and diarrhoea.

Serious adverse reactions occurred in 52% of patients. The most frequent serious adverse reaction (≥ 10%) was cytokine release syndrome (31%). Seven patients (4.2%) experienced a fatal adverse reaction (pneumonia in 3 (1.8%) patients, viral infection in 3 (1.8%) patients, and ICANS in 1 (0.6%) patient). Adverse reactions that led to discontinuation occurred in 6.6% of patients. Discontinuation of Tepkinly due to pneumonia occurred in 6 (3.6%) patients, viral infection in 3 (1.8%) patients, and CRS, ICANS, or fatigue in 1 (0.6%) patient each. Dose delays due to adverse reactions occurred in 32% of patients. Adverse reactions leading to dose delays (≥ 3%) were viral infections (9.6%), CRS (7.2%), neutropenia (4.8%), pyrexia (3.0%), and thrombocytopenia (3.0%).

About RD118

RD118 is an autologous T-cell immunotherapy product targeting G protein-coupled receptor class C group 5 member D (GPRC5D). It can identify and eliminate malignant tumor cells expressing GPRC5D. GPRC5D is highly expressed on multiple myeloma cells. However, in normal tissues, its expression is limited to plasma cells and hair follicle cells. Such a feature has made GPRC5D a promising safe and effective target for the treatment of multiple myeloma.

The antigen recognition domain of RD118 is developed from IASO Bio’s proprietary fully human single-domain antibody library. It has advantages of high affinity, high specificity, and low immunogenicity. The intracellular domain is a fusion of 4-1BB (CD137) and CD3ζ signaling domains. RD118 has been subjected to extensive development and optimization in terms of antibody screening and structure design. The candidate molecule has demonstrated excellent in vitro cytotoxic activity and in vivo tumor suppression ability. Additionally, it has good expansion capability and persistence in vivo, indicating high development potential.

An investigator-initiated clinical trial (IIT) (ClinicalTrials.gov identifier: NCT05759793, NCT05219721) is being conducted to preliminary investigate the safety and efficacy of RD118 injection in patients with RRMM or plasma cell leukemia. The principal investigators are Professor Jianqing Mi from Ruijin Hospital, Shanghai Jiao Tong University School of Medicine and Professor Chunrui Li from Tongji Hospital, Tongji Medical College of Huazhong University of Science and Technology.

The trial enrolled patients with multiple myeloma or plasma cell leukemia who have previously received at least three lines of therapy (must include at least one proteasome inhibitor and one immunomodulator). Patients who have previously received BCMA CAR-T therapy can also be enrolled. The trial investigated RD118 at the doses of 1.0–3.0 × 106 CAR-T cells/kg. As of Nov. 20, 2023, the dose-escalation phase has completed subject enrollment and infusion. The subjects who received infusion have demonstrated good safety and efficacy profiles. Patients with prior BCMA CAR-T therapy have also shown benefits.

Professor Mi Jianqing, Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, stated: " Studies have shown that malignant plasma cells in almost all multiple myeloma patients express GPRC5D. The GPRC5D-targeting therapy has been demonstrated to effectively control disease progression and prolong overall survival of patients with multiple myeloma, which makes GPRC5D an emerging competitive target. Furthermore, GPRC5D has been shown to be expressed on the surface of myeloma cells independently of BCMA, and its expression is not affected by the loss of BCMA. Patients who experience a relapse after anti-BCMA CAR-T cell therapy may still respond effectively to the treatment with anti-GPRC5D CAR-T cells, further indicating that anti-GPRC5D CAR-T is a candidate therapy with potential."

Professor Chunrui Li, Tongji Hospital, Tongji Medical College, Huazhong University of Science & Technology, stated: "The development of CAR-T cell therapy has significantly changed the treatment landscape for multiple myeloma. The current therapies for multiple myeloma are mainly BCMA-targeted. However, the heterogeneous expressions of BCMA on a majority of malignant plasma cells may lead to varying degrees of therapeutic response among different patients. The results of this IIT study demonstrated that RD118 has shown positive therapeutic effects and controllable safety in patients who have experienced target escape from BCMA-targeted therapy, as well as in those with low or unstable BCMA expression. This may provide a new therapeutic approach for patients with RRMM, which is of substantial clinical value. In future clinical studies, we will continue to investigate the optimal treatment sequence and strategy for GPRC5D-targeting therapy."

Ms. Jinhua Zhang, Founder and Chairman of IASO Bio, stated, "GPRC5D is expressed on myeloma cells. And just like BCMA, GPRC5D is one of the key targets for treating multiple myeloma. Multiple myeloma is a complex disease and requires different treatment strategies to address various patient conditions. Developed by IASO Bio, RD118 is a GPRC5D-targeting cell product for the treatment of multiple myeloma and has demonstrated significant therapeutic potential in the exploratory clinical trial, offering a new therapeutic approach for both medical professionals and patients. We are excited about the prospects of RD118 and will continue to conduct in-depth research to ensure its safety and efficacy in clinical practice. At the same time, we will continue our collaboration with global medical experts and research institutions to jointly promote the development of this field and bring more benefits to patients."

On June 28, 2024 BridGene Biosciences, Inc., a leader in developing covalent small molecule drugs for traditional "hard-to-drug" targets, reported that the first patient has been dosed in its Phase 1 clinical trial of BGC515, a novel TEAD inhibitor discovered through BridGene’s cutting-edge chemoproteomic platform, IMTAC (Press release, Bridgene Biosciences, JUN 28, 2024, View Source [SID1234644599]).

The Phase 1 study will enroll subjects in both the US and China (NCT06452160) to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary antitumor activity of BGC515 as a single agent in patients with advanced solid tumors, including malignant mesothelioma, epithelioid hemangioendothelioma, and other solid tumors with hippo pathway dysregulation. Dr. Timothy Yap, Ph.D., FRCP, Professor in the Department of Investigational Cancer Therapeutics (Phase I Program) and Head of Clinical Development, Therapeutics Discovery Division at the University of Texas MD Anderson Cancer Center, is the principal investigator at the initial US site, where the first patient has been enrolled.

"We are delighted to begin the clinical evaluation of BGC515 with the dosing of our first patient, and we look forward to the evaluation of the initial safety and efficacy of this exciting compound," said Jeremy Barton, M.D., Chief Medical Officer of BridGene Biosciences.

"The initiation and dosing of our first drug in clinical development from our chemoproteomic platform marks a major inflection point for BridGene," stated Ping Cao, Ph.D., Co-Founder and CEO of BridGene Biosciences. "This achievement underscores our commitment to addressing unmet medical needs through innovative therapeutic solutions. BGC515 represents a breakthrough in targeting the TEAD proteins, a critical component in the Hippo signaling pathway. We are proud of the progress we have made in a short time, developing a pipeline that includes previously undruggable targets for prominent oncology and immunology diseases."

BridGene Biosciences is advancing multiple novel drug discovery programs toward the clinic and has over a dozen similar opportunities emerging in early discovery.

About the Hippo Pathway and BGC515
The Hippo pathway is a key pathway used by cells to control expression of a group of genes by regulating activity of transcription factors YAP and TAZ. YAP and TAZ function in a complex with partner proteins, the TEADs, which are the targets of BGC515. A variety of human cancers depend on activation of YAP and TAZ, which can occur by various mechanisms.

BGC515 is an internally-developed, orally-administered, covalent TEAD inhibitor.

On June 28, 2024 Agenus Inc. ("Agenus") (Nasdaq: AGEN), a leader in developing novel immunological agents to treat various cancers, reported results from an investigator-sponsored trial (IST) of botensilimab and balstilimab (BOT/BAL) in the neoadjuvant setting for colon cancer (Press release, Agenus, JUN 28, 2024, View Source [SID1234644598]). Data were presented at the 2024 European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) Gastrointestinal Cancers Congress in Munich, Germany.

Dr. Pashtoon Kasi, the originator of this groundbreaking study, stated, "The rapid and complete resolution of aggressive MSS colorectal cancer tumors observed in this study is unprecedented in the field. The exceptional activity of the BOT/BAL combination therapy in the neoadjuvant setting offers new hope for patients facing this challenging cancer subtype. Furthermore, the pattern of response and the lack of clinical recurrence speaks to the curative potential of one’s own body to fight cancer."

Study Highlights:

Enrollment: 20 patients were evaluable at the data cutoff with available pathology results, 17 microsatellite stable (MSS) and 3 high microsatellite instability (MSI-H).
Treatment Regimens: Both cohorts received one dose of botensilimab with balstilimab. The NEST-1 cohort received one additional dose of balstilimab two weeks later, whereas the NEST-2 cohort received up to 3 additional doses of balstilimab.
Clinical Findings:

Pathologic Response: In the NEST-2 cohort, 78% (7/9) of MSS patients achieved pathologic responses of at least 50% tumor regression, with 56% (5/9) reaching complete pathologic responses.
Surgical Outcomes and Safety: No surgeries were delayed due to adverse events, and no patients had unresolved immune related adverse events. Side effects were manageable, and no new safety concerns emerged.

About Botensilimab

Botensilimab is a human Fc enhanced CTLA-4 blocking antibody designed to boost both innate and adaptive anti-tumor immune responses. Its novel design leverages mechanisms of action to extend immunotherapy benefits to "cold" tumors which generally respond poorly to standard of care or are refractory to conventional PD-1/CTLA-4 therapies and investigational therapies. Botensilimab augments immune responses across a wide range of tumor types by priming and activating T cells, downregulating intratumoral regulatory T cells, activating myeloid cells and inducing long-term memory responses.

Approximately 900 patients have been treated with botensilimab in phase 1 and phase 2 clinical trials. Botensilimab alone, or in combination with Agenus’ investigational PD-1 antibody, balstilimab, has shown clinical responses across nine metastatic, late-line cancers. For more information about botensilimab trials, visit www.clinicaltrials.gov with the identifiers NCT03860272, NCT05608044, NCT05630183, and NCT05529316.

About Colorectal Cancer

Colorectal cancer (CRC) is the second leading cause of cancer death in the United States, comprising an estimated 8.3% of cancer-related deaths annually. Although overall mortality from CRC has declined, survival remains poor for advanced disease, and the burden is shifting to a younger population. Alarmingly, from 1995 to 2019, the number of patients under the age of 55 who were diagnosed with CRC in the United States nearly doubled.

On June 28, 2024 Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) reported that the European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP) has adopted a positive opinion recommending conditional marketing authorization of odronextamab to treat adults with relapsed/refractory (R/R) follicular lymphoma (FL) or R/R diffuse large B-cell lymphoma (DLBCL), after two or more lines of systemic therapy (Press release, Regeneron, JUN 28, 2024, View Source [SID1234644595]). The European Commission is expected to announce a final decision in the coming months.

FL and DLBCL are the two most common subtypes of B-cell non-Hodgkin lymphoma (B-NHL). While FL is a slow-growing subtype, it is an incurable disease, and most patients will relapse after initial treatment. DLBCL is an aggressive subtype, with up to 50% of high-risk patients experiencing progression after first-line treatment (e.g., relapsing or refractory to treatment). It is estimated that approximately 120,000 FL cases and 163,000 DLBCL cases are diagnosed annually worldwide. In Europe, it is estimated that approximately 15,000 FL cases and 31,000 DLBCL cases are diagnosed each year.

The positive CHMP opinion is supported by results from the Phase 1 ELM-1 and pivotal Phase 2 ELM-2 trials, which demonstrated robust, durable response rates and an acceptable safety profile of odronextamab in adults with R/R FL or R/R DLBCL. In a pooled safety population, the most common serious adverse reactions were cytokine release syndrome, pneumonia, COVID-19 and pyrexia.

The EMA previously granted odronextamab Orphan Designation for both FL and DLBCL. Odronextamab is currently under clinical development and has not been approved by any regulatory authority.

Regeneron continues to evaluate the use of odronextamab as a monotherapy and in combination across earlier lines of therapy in challenging-to-treat lymphomas. This includes the registrational ELM-1 and ELM-2 studies, the Phase 3 OLYMPIA development program, which is one of the largest clinical programs in lymphoma evaluating odronextamab in earlier lines of therapy and additional B-NHLs, as well as early-stage trials with chemotherapy-free combinations.

About the Odronextamab Clinical Trial Program
Odronextamab is an investigational CD20xCD3 bispecific antibody designed to bridge CD20 on cancer cells with CD3-expressing T cells to facilitate local T-cell activation and cancer-cell killing.

ELM-1 is an ongoing, open-label, multicenter Phase 1 trial to investigate the safety and tolerability of odronextamab in patients with CD20+ B-cell malignancies previously treated with CD20-directed antibody therapy, including a cohort of patients who had progressed after CAR-T therapy.

ELM-2 is an ongoing, open-label, multicenter Phase 2 trial investigating odronextamab across five independent disease-specific cohorts, including DLBCL, FL, mantle cell lymphoma, marginal zone lymphoma and other subtypes of B-NHL. The primary endpoint is objective response rate according to the Lugano Classification as assessed by independent review committee, and secondary endpoints include complete response, progression-free survival, overall survival and duration of response.

In addition to the Phase 3 OLYMPIA development program, Regeneron is investigating odronextamab in combination with a costimulatory bispecific antibody, REGN5837 (CD22xCD28), and Regeneron’s PD-1 inhibitor cemiplimab for R/R aggressive B-NHL through the ATHENA-1 and CLIO-1 studies, respectively.
