First Phase 3 data to be reported from a trial evaluating an anti-LAG-3 antibody

Relatlimab is the company’s third distinct checkpoint inhibitor to demonstrate a benefit for patients

PRINCETON, N.J.--(BUSINESS WIRE)-- Bristol Myers Squibb (NYSE: BMY) today announced primary results from the Phase 2/3 RELATIVITY-047 (CA224-047) trial evaluating the fixed-dose combination of relatlimab, an anti-LAG-3 antibody, and Opdivo (nivolumab) versus Opdivo alone in patients with previously untreated metastatic or unresectable melanoma. The trial met its primary endpoint of progression-free survival (PFS). Follow up for overall survival, a secondary endpoint, is ongoing. The fixed-dose combination was well-tolerated and there were no new safety signals reported in either the relatlimab and Opdivo combination arm or the Opdivo arm. These are the first Phase 3 data to be reported from a trial evaluating an anti-LAG-3 antibody. Relatlimab is the third distinct checkpoint inhibitor (anti-PD-1, anti-CTLA-4 and anti-LAG-3) for Bristol Myers Squibb and, with Opdivo, the first fixed-dose combination to demonstrate a benefit for patients.

“Immune checkpoint inhibitors alone or in combination have transformed treatment and improved survival rates for patients with metastatic or unresectable melanoma. However, there remain a considerable number of patients who could benefit from a novel combination therapy that leverages potentially complementary pathways to improve anti-tumor activity,” said Jonathan Cheng, senior vice president and head of oncology development, Bristol Myers Squibb. “The results of this study suggest that targeting the LAG-3 pathway in combination with PD-1 inhibition may be a key strategy to enhance the immune response and help improve outcomes for these patients.”

Lymphocyte-activation gene 3 (LAG-3) is a cell-surface molecule expressed on effector T cells and regulatory T cells (Tregs). LAG-3 regulates an inhibitory immune checkpoint pathway that limits the activity of T cells, leading to an impaired ability to attack tumor cells. In the chronic presence of diseases like cancer, T cells exhibit progressive exhaustion that is characterized by the upregulation of inhibitory immune checkpoints such as PD-1 and LAG-3. While LAG-3 and PD-1 are distinct immune checkpoint pathways, they may potentially act synergistically on effector T cells leading to T cell exhaustion. Relatlimab is a LAG-3–blocking antibody that binds to LAG-3 on T cells, restoring effector function of exhausted T cells. Relatlimab, in combination with Opdivo, is the first anti-LAG-3 antibody to demonstrate a benefit for patients.

Bristol Myers Squibb will present the results at an upcoming meeting and discuss these results with regulatory authorities.

Bristol Myers Squibb thanks the patients and investigators who were involved in the RELATIVITY-047 clinical trial. The company has several ongoing trials evaluating the use of relatlimab in combination with Opdivo and other therapies for the treatment of additional cancers.

About RELATIVITY-047 (CA224-047)

RELATIVITY-047 (CA224-047) is a randomized, double-blind Phase 2/3 study evaluating the fixed-dose combination of relatlimab and Opdivo in patients with previously untreated metastatic or unresectable melanoma versus Opdivo alone. The primary endpoint of the trial is progression-free survival (PFS) by Blinded Independent Central Review (BICR) and the secondary endpoints are overall survival (OS) and objective response rate (ORR). A total of 714 patients were randomized 1:1 to receive a fixed-dose combination of relatlimab 160 mg and Opdivo 480 mg or Opdivo 480 mg by intravenous infusion every four weeks until disease recurrence, unacceptable toxicity or withdrawal of consent. Follow up for the secondary endpoints of OS and ORR is ongoing.

About LAG-3

Lymphocyte-activation gene 3 (LAG-3) is a cell-surface molecule expressed on effector T cells and regulatory T cells (Tregs) and functions to control T cell response, activation and growth. Preclinical studies indicate that inhibition of the LAG-3 pathway may restore effector function of exhausted T cells and potentially promote an anti-tumor response. Early research demonstrates that targeting the LAG-3 pathway in combination with other potentially complementary immune pathways may be a key strategy to more effectively potentiate anti-tumor immune activity.

Bristol Myers Squibb is evaluating relatlimab, its LAG-3-blocking antibody, in clinical trials in combination with other agents in a variety of tumor types.

About Melanoma

Melanoma is a form of skin cancer characterized by the uncontrolled growth of pigment-producing cells (melanocytes) located in the skin. Metastatic melanoma is the deadliest form of the disease and occurs when cancer spreads beyond the surface of the skin to other organs. The incidence of melanoma has been increasing steadily for the last 30 years. In the United States, 106,110 new diagnoses of melanoma and about 7,180 related deaths are estimated for 2021. Globally, the World Health Organization estimates that by 2035, melanoma incidence will reach 424,102, with 94,308 related deaths. Melanoma is mostly curable when treated in its very early stages; however, survival rates decrease if regional lymph nodes are involved.

About Opdivo®

Opdivo is a programmed death-1 (PD-1) immune checkpoint inhibitor that is designed to uniquely harness the body’s own immune system to help restore anti-tumor immune response. By harnessing the body’s own immune system to fight cancer, Opdivo has become an important treatment option across multiple cancers.

Opdivo’s leading global development program is based on Bristol Myers Squibb’s scientific expertise in the field of Immuno-Oncology and includes a broad range of clinical trials across all phases, including Phase 3, in a variety of tumor types. To date, the Opdivo clinical development program has treated more than 35,000 patients. The Opdivo trials have contributed to gaining a deeper understanding of the potential role of biomarkers in patient care, particularly regarding how patients may benefit from Opdivo across the continuum of PD-L1 expression.

In July 2014, Opdivo was the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world. Opdivo is currently approved in more than 65 countries, including the United States, the European Union, Japan and China. In October 2015, the Company’s Opdivo and Yervoy combination regimen was the first Immuno-Oncology combination to receive regulatory approval for the treatment of metastatic melanoma and is currently approved in more than 50 countries, including the United States and the European Union.

IMPORTANT SAFETY INFORMATION

Severe and Fatal Immune-Mediated Adverse Reactions

Immune-mediated adverse reactions listed herein may not include all possible severe and fatal immune-mediated adverse reactions.

Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue. While immune-mediated adverse reactions usually manifest during treatment, they can also occur after discontinuation of OPDIVO or YERVOY. Early identification and management are essential to ensure safe use of OPDIVO and YERVOY. Monitor for signs and symptoms that may be clinical manifestations of underlying immune-mediated adverse reactions. Evaluate clinical chemistries including liver enzymes, creatinine, adrenocorticotropic hormone (ACTH) level, and thyroid function at baseline and periodically during treatment with OPDIVO and before each dose of YERVOY. 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 OPDIVO and YERVOY depending on severity (please see section 2 Dosage and Administration in the accompanying Full Prescribing Information). In general, if OPDIVO or YERVOY interruption or discontinuation is required, 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 immune-mediated adverse reactions are not controlled with corticosteroid therapy. Toxicity management guidelines for adverse reactions that do not necessarily require systemic steroids (e.g., endocrinopathies and dermatologic reactions) are discussed below.

Immune-Mediated Pneumonitis

OPDIVO and YERVOY can cause immune-mediated pneumonitis. The incidence of pneumonitis is higher in patients who have received prior thoracic radiation. In patients receiving OPDIVO monotherapy, immune-mediated pneumonitis occurred in 3.1% (61/1994) of patients, including Grade 4 (
