Warnings and precautions

• Immune-Mediated Adverse Reactions : (5.1) o Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue, including the following: immune-mediated pneumonitis, immune-mediated colitis, immune-mediated hepatitis, immune-mediated endocrinopathies, immune-mediated dermatologic adverse reactions, immune-mediated nephritis with renal dysfunction, and immune-mediated myocarditis. o Monitor for early identification and management. Evaluate liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment. o Withhold or permanently discontinue based on severity and type of reaction. (2.2)
• Infusion-related reactions : Interrupt, slow the rate of infusion, or permanently discontinue OPDUALAG based on severity of reaction. ( 2.2 , 5.2 )
• Complications of allogeneic HSCT : Fatal and other serious complications can occur in patient who receive allogeneic HSCT before or after being treated with a PD-1/PD-L1 blocking antibody. (5.3)
• Embryo-fetal toxicity : Can cause fetal harm. Advise females of reproductive potential of potential risk to a fetus and to use effective contraception. ( 5.4 , 8.1 , 8.3 ) 5.1 Severe and Fatal Immune-Mediated Adverse Reactions OPDUALAG potentially breaks peripheral tolerance and induces immune-mediated adverse reactions (IMARs) [see Clinical Pharmacology (12.1) ] . Important IMARs listed under Warnings and Precautions may not include all possible severe and fatal IMARs. IMARs, which may be severe or fatal, can occur in any organ system or tissue. IMARs can occur at any time after starting treatment with a LAG-3 and PD-1/PD-L1 blocking antibodies. While IMARs usually manifest during treatment, IMARs can also manifest after discontinuation. Early identification and management of IMARs are essential to ensure safe use. Monitor patients closely for symptoms and signs that may be clinical manifestations of underlying IMARs. Evaluate liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment. In cases of suspected IMARs, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate. Withhold or permanently discontinue OPDUALAG depending on severity [see Dosage and Administration (2.2) ] . In general, if OPDUALAG requires interruption or discontinuation, administer systemic corticosteroid therapy (1 to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose IMARs 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 OPDUALAG can cause immune-mediated pneumonitis, which may be fatal. In patients treated with other PD-1/PD-L1 blocking antibodies, the incidence of pneumonitis is higher in patients who have received prior thoracic radiation. Immune-mediated pneumonitis occurred in 3.7% (13/355) of patients receiving OPDUALAG, including Grade 3 (0.6%), and Grade 2 (2.3%) adverse reactions. Pneumonitis led to permanent discontinuation of OPDUALAG in 0.8% and withholding of OPDUALAG in 1.4% of patients. Systemic corticosteroids were required in 100% (13/13) of patients with pneumonitis. Pneumonitis resolved in 85% of the 13 patients. Of the 5 patients in whom OPDUALAG was withheld for pneumonitis, 5 reinitiated OPDUALAG after symptom improvement; of these, none had recurrence of pneumonitis. Immune-Mediated Colitis OPDUALAG can cause immune-mediated colitis, defined as requiring use of corticosteroids and no clear alternate etiology. A common symptom included in the definition of colitis was diarrhea. Cytomegalovirus infection/reactivation has been reported in patients with corticosteroid-refractory immune-mediated colitis. In cases of corticosteroid-refractory colitis, consider repeating infectious workup to exclude alternative etiologies. Immune-mediated diarrhea or colitis occurred in 7% (24/355) of patients receiving OPDUALAG, including Grade 3 (1.1%) and Grade 2 (4.5%) adverse reactions. Colitis led to permanent discontinuation of OPDUALAG in 2% and withholding of OPDUALAG in 2.8% of patients. Systemic corticosteroids were required in 100% (24/24) of patients with diarrhea or colitis. Colitis resolved in 83% of the 24 patients. Of the 10 patients in whom OPDUALAG was withheld for colitis, 9 reinitiated OPDUALAG after symptom improvement; of these, 67% had recurrence of colitis. Immune-Mediated Hepatitis OPDUALAG can cause immune-mediated hepatitis, defined as requiring the use of corticosteroids and no clear alternate etiology. Immune-mediated hepatitis occurred in 6% (20/355) of patients receiving OPDUALAG, including Grade 4 (0.6%), Grade 3 (3.4%), and Grade 2 (1.4%) adverse reactions. Hepatitis led to permanent discontinuation of OPDUALAG in 1.7% and withholding of OPDUALAG in 2.3% of patients. Systemic corticosteroids were required in 100% (20/20) of patients with hepatitis. Hepatitis resolved in 70% of the 20 patients. Of the 8 patients in whom OPDUALAG was withheld for hepatitis, 6 reinitiated OPDUALAG after symptom improvement; of these, 50% had recurrence of hepatitis. Immune-Mediated Endocrinopathies Adrenal Insufficiency OPDUALAG can cause primary or secondary adrenal insufficiency. For Grade 2 or higher adrenal insufficiency, initiate symptomatic treatment, including hormone replacement as clinically indicated. Withhold OPDUALAG depending on severity [see Dosage and Administration (2.2) ] . Adrenal insufficiency occurred in 4.2% (15/355) of patients receiving OPDUALAG, including Grade 3 (1.4%) and Grade 2 (2.5%) adverse reactions.

Side effects

The following clinically significant adverse reactions are discussed in greater detail in other sections of the labeling.
• Severe and Fatal IMARs [see Warnings and Precautions (5.1) ]
• Infusion-Related Reactions [see Warnings and Precautions (5.2) ]
• Complications of Allogeneic HSCT [see Warnings and Precautions (5.3) ] The most common adverse reactions (≥20%) are musculoskeletal pain, fatigue, rash, pruritus, and diarrhea. (6.1) The most common laboratory abnormalities (≥20%) are decreased hemoglobin, decreased lymphocytes, increased AST, increased ALT, and decreased sodium. (6.1) To report SUSPECTED ADVERSE REACTIONS, contact Bristol-Myers Squibb at 1-800-721-5072 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety of OPDUALAG was evaluated in RELATIVITY-047, a randomized (1:1), double-blinded trial in 714 patients with previously untreated metastatic or unresectable melanoma [see Clinical Studies (14) ] . Patients received intravenous OPDUALAG (nivolumab 480 mg and relatlimab 160 mg) every 4 weeks (n=355) or nivolumab 480 mg by intravenous infusion every 4 weeks (n=359). Patients were treated with OPDUALAG or nivolumab until disease progression or unacceptable toxicity. The median duration of exposure was 6 months (range: 0 to 31 months) in OPDUALAG-treated patients and 5 months (range: 0 to 32 months) in nivolumab-treated patients. Serious adverse reactions occurred in 36% of patients treated with OPDUALAG. The most frequent serious adverse reactions reported in ≥1% of patients treated with OPDUALAG were adrenal insufficiency (1.4%), anemia (1.4%), colitis (1.4%), pneumonia (1.4%), acute myocardial infarction (1.1%), back pain (1.1%), diarrhea (1.1%), myocarditis (1.1%), and pneumonitis (1.1%). Fatal adverse reaction occurred in 3 (0.8%) patients who were treated with OPDUALAG; these included hemophagocytic lymphohistiocytosis, acute edema of the lung, and pneumonitis. OPDUALAG was permanently discontinued due to adverse reactions in 18% of patients. Adverse reactions which resulted in permanent discontinuation of OPDUALAG in ≥1% of patients included myocarditis (1.7%) and pneumonitis (1.4%). Dosage interruptions due to an adverse reaction occurred in 43% of patients who received OPDUALAG. Adverse reactions that required dosage interruption in ≥2% of patients who received OPDUALAG were diarrhea (3.9%), troponin increased (3.9%), AST increased (2.8%), troponin T increased (2.8%), ALT increased (2.3%), arthralgia (2.3%), hypothyroidism (2.3%), anemia (2%), fatigue (2%), pneumonitis (2%), and rash (2%). The most common (≥20%) adverse reactions that occurred in patients treated with OPDUALAG were musculoskeletal pain (45%), fatigue (39%), rash (28%), pruritus (25%), and diarrhea (24%). The most common (≥20%) laboratory abnormalities that occurred in patients treated with OPDUALAG were decreased hemoglobin (37%), decreased lymphocytes (32%), increased AST (30%), increased ALT (26%), and decreased sodium (24%). Tables 3 and 4 summarize both the adverse reactions and laboratory abnormalities, respectively, in RELATIVITY-047.

Use in specific populations

• Lactation: Advise not to breastfeed. (8.2) 8.1 Pregnancy Risk Summary Based on findings in animals and mechanism of action, OPDUALAG can cause fetal harm when administered to a pregnant woman. Administration of nivolumab to cynomolgus monkeys from the onset of organogenesis through delivery resulted in increased abortion and premature infant death ( see Data ). Human IgG4 is known to cross the placenta; therefore, nivolumab and relatlimab have the potential to be transmitted from the mother to the developing fetus. The effects of OPDUALAG are likely to be greater during the second and third trimesters of pregnancy. There are no available data on OPDUALAG in pregnant women to evaluate a drug-associated risk. Advise the patient of the potential risk to a fetus. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data OPDUALAG injection for intravenous use contains nivolumab and relatlimab [see Description (11) ] . Nivolumab: One function of the PD-1/PD-L1 pathway is to preserve pregnancy by maintaining immune tolerance to the fetus. The effects of nivolumab on prenatal and postnatal development were evaluated in monkeys that received nivolumab twice weekly from the onset of organogenesis through delivery, at exposure levels of between 9 and 42 times higher than those observed at the clinical dose of 3 mg/kg (based on AUC). Nivolumab administration resulted in a non-dose-related increase in spontaneous abortion and increased neonatal death. In surviving infants (18 of 32 compared to 11 of 16 vehicle-exposed infants) of cynomolgus monkeys treated with nivolumab, there were no apparent malformations and no effects on neurobehavioral, immunological, or clinical pathology parameters throughout the 6-month postnatal period. Relatlimab: There are no available animal data on relatlimab. The effects of a murine surrogate anti-LAG-3 antibody was evaluated in mice using syngeneic and allogeneic breeding models. When anti-LAG-3 antibodies were administered beginning on gestation day 6, there were no maternal or developmental effects in either syngeneic or allogeneic breedings. 8.2 Lactation Risk Summary There are no data on the presence of nivolumab and relatlimab in human milk, the effects on the breastfed child, or the effects on milk production. Because nivolumab and relatlimab may be excreted in human milk and because of the potential for serious adverse reactions in a breastfed child, advise patients not to breastfeed during treatment with OPDUALAG and for at least 5 months after the last dose [see Pharmacokinetics (12.3) ] . 8.3 Females and Males of Reproductive Potential OPDUALAG can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1) ] . Pregnancy Testing Verify the pregnancy status of females of reproductive potential prior to initiating OPDUALAG [see Use in Specific Populations (8.1) ] . Contraception Advise females of reproductive potential to use effective contraception during treatment and for at least 5 months following the last dose of OPDUALAG [see Clinical Pharmacology (12.3) ] . 8.4 Pediatric Use The safety and effectiveness of OPDUALAG for the treatment of unresectable or metastatic melanoma have been established in pediatric patients 12 years of age or older who weigh at least 40 kg. Use of OPDUALAG for this indication is supported by evidence from an adequate and well-controlled study in adults and additional data analyses that suggest that nivolumab and relatlimab exposures in pediatric patients 12 years of age who weigh at least 40 kg are expected to result in similar safety and efficacy to that of adults. The pharmacokinetics of monoclonal antibodies and the course of unresectable or metastatic melanoma are sufficiently similar in adults and pediatric patients 12 years of age or older to allow extrapolation of data from adult patients to pediatric patients 12 years of age or older (who weigh at least 40 kg). A recommended dosage for pediatric patients 12 years of age or older who weigh less than 40 kg has not been established [see Adverse Reactions (6.1) , Clinical Pharmacology (12.3) , and Clinical Studies (14) ] . The safety and effectiveness of OPDUALAG have not been established in pediatric patients 12 years of age or older who weigh less than 40 kg, and pediatric patients younger than 12 years of age. 8.5 Geriatric Use Of the 355 patients treated with OPDUALAG in RELATIVITY-047, 47% of patients were 65 years or older, 29% were 65 to 74 years, 17% were 75 to 84 years, and 1.7% were 85 years and older. No overall differences in safety or effectiveness were observed between elderly patients and younger patients.

No overall differences in safety or effectiveness were observed between elderly patients and younger patients.

Description

Nivolumab and relatlimab-rmbw is a fixed-dose combination of two IgG4 kappa monoclonal antibodies (mAbs). Nivolumab is a programmed death receptor-1 (PD-1) blocking antibody that has a calculated molecular mass of 146 kDa and is expressed in a recombinant Chinese Hamster Ovary (CHO) cell line. Relatlimab is a lymphocyte activation gene-3 (LAG-3) blocking antibody that has a calculated molecular mass of 148 kDa and is expressed in a recombinant CHO cell line. OPDUALAG (nivolumab and relatlimab-rmbw) injection is a sterile, preservative-free, clear to opalescent, colorless to slightly yellow solution that may contain few translucent-to-white particles. OPDUALAG is supplied as 240 mg of nivolumab and 80 mg of relatlimab in a 20 mL single-dose vial for intravenous use. Each mL of OPDUALAG solution contains 12 mg of nivolumab, 4 mg of relatlimab, and histidine (1.1 mg), L-histidine hydrochloride monohydrate (2.7 mg), pentetic acid (0.008 mg), polysorbate 80 (0.5 mg), sucrose (85.6 mg), and Water for Injection, USP. The pH is 5.8.

Mechanism of action

12.1 Mechanism of Action Relatlimab is a human IgG4 monoclonal antibody that binds to the LAG-3 receptor, blocks interaction with its ligands, including MHC II, and reduces LAG-3 pathway-mediated inhibition of the immune response. Antagonism of this pathway promotes T cell proliferation and cytokine secretion. Binding of the PD-1 ligands, PD-L1 and PD-L2, to the PD-1 receptor found on T cells, inhibits T-cell proliferation and cytokine production. Upregulation of PD-1 ligands occurs in some tumors, and signaling through this pathway can contribute to inhibition of active T-cell immune surveillance of tumors. Nivolumab is a human IgG4 monoclonal antibody that binds to the PD-1 receptor, blocks interaction with its ligands PD-L1 and PD-L2, and reduces PD-1 pathway-mediated inhibition of the immune response, including the anti-tumor immune response. In syngeneic mouse tumor models, blocking PD-1 activity resulted in decreased tumor growth. The combination of nivolumab (anti-PD-1) and relatlimab (anti-LAG-3) results in increased T-cell activation compared to the activity of either antibody alone. In murine syngeneic tumor models, LAG-3 blockade potentiates the anti-tumor activity of PD-1 blockage, inhibiting tumor growth and promoting tumor regression.
