In 2025, melanoma is estimated to result in more than 104,000 new cases in the United States.1 Metastatic melanoma (also known as advanced melanoma) is the deadliest form of melanoma, representing about 10% of all cases, and occurs when cancer spreads beyond the surface of the skin to other organs.2,3,4
An Immunotherapy Option in Advanced Melanoma
Dual immunotherapy (IO), which is two immunotherapies working together, has changed how advanced melanoma can be treated for many patients, as it’s designed to leverage the body’s own immune system to help recognize and target tumor cells.5 The first dual IO medication for the first-line treatment of metastatic melanoma, Opdivo® (nivolumab) plus Yervoy® (ipilimumab), was approved nearly 10 years ago.6,14,15 Since then, dual IO has become a critical pillar in advanced melanoma treatment, and scientific progress with dual IO helped inform the development of Opdualag™ (nivolumab and relatlimab-rmbw), a combination immunotherapy using nivolumab in combination with a different immunotherapy, called relatlimab.7,8
Opdualag is a treatment option in advanced melanoma, regardless of BRAF mutation status, for adults and children 12 years of age or older.7 It is designed to work by connecting to tired T cells and activating them so they can help the immune system attack cancer.7 It is not known if Opdualag is safe and effective when used in children younger than 12 years of age or older who weigh less than 88 pounds (40 kg).7
How Opdualag works12
All therapies have the potential to result in adverse reactions. Opdualag can cause serious side effects any time during and after treatment. The most serious side effects include: immune system-related side effects; severe infusion reactions and complications with donor stem cell (allogeneic) transplants. The most common side effects include: muscle and bone pain; tiredness; decreased red blood cell and white blood cell counts; increased liver function test results; rash; itching, diarrhea; decreased salt (sodium) in your blood. Immune system-related side effects may include: lung problems; intestinal problems; liver problems; hormone gland problems; kidney problems; skin problems; heart problems; problems in other organs and tissues.7 Please see additional Important Safety Information below and click here for the full Prescribing Information.
Diving Into the Primary Data
Opdualag was approved in 2022 by the U.S. Food and Drug Administration for the treatment of adult and pediatric patients 12 years of age or older with unresectable or metastatic melanoma.7 The approval was based on the RELATIVITY-047 trial—a global, randomized, double-blind Phase 2/3 study evaluating Opdualag versus nivolumab alone in patients with previously untreated metastatic or unresectable melanoma.7
A total of 714 patients were randomized to receive either Opdualag (n=355) as a fixed-dose combination or nivolumab (n=359) alone which were administered intravenously every four weeks to patients with previously untreated metastatic or unresectable melanoma.9 The primary endpoint was progression-free survival (PFS) as assessed by Blinded Independent Central Review (BICR).9
In the primary analysis at 13.2 months of median follow-up, the trial met its primary endpoint, PFS.7,9 Opdualag more than doubled the median PFS when compared to nivolumab monotherapy, 10.1 months (95% Confidence Interval [CI]: 6.4 to 15.7) versus 4.6 months (95% CI: 3.4 to 5.6), respectively; (Hazard Ratio [HR] 0.75; 95% CI: 0.62 to 0.92, P=0.0055).7,9 No additional safety events and similar rates of most common grade 3/4 adverse reactions were identified compared to nivolumab monotherapy.7,9

Follow-Up Study Results
Now, there’s updated 33.8-month median follow-up data for the RELATIVITY-047 study.10 The results include PFS of Opdualag vs. nivolumab monotherapy in patients with previously untreated metastatic or unresectable melanoma.10 In this 33.8-month median follow-up study, PFS per BICR using RECIST v1.1 at 36 months was 32% for the Opdualag arm (n=355) vs. 27% for the nivolumab monotherapy arm (n=359).10
The results also include PFS of Opdualag vs. nivolumab monotherapy in BRAF mutant patients with previously untreated metastatic or unresectable melanoma.10,13 In this 33.8-month median follow-up study, for the BRAF mutant population, PFS per BICR using RECIST v1.1 at 36 months was 33% for the Opdualag arm (n=136) vs. 21% for the nivolumab monotherapy arm (n=139).13

For Oncologists: Opdualag’s Potential for Eligible Advanced Melanoma Patients
In the ever-evolving oncology field, it’s important to stay abreast of the latest treatment developments. Opdualag has helped progress dual IO as a one-of-a-kind approved treatment that joins two immunotherapies into one.7
In the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines®) for Melanoma: Cutaneous, nivolumab and relatlimab-rmbw (Opdualag) is recommended as a category 1, preferred treatment option for unresectable or metastatic melanoma, regardless of BRAF status.11
Oncologists are encouraged to visit www.opdualaghcp.com to learn more about the mechanism of action, safety and prescribing information of Opdualag to help inform their treatment recommendations for their advanced melanoma patients.
INDICATION
OPDIVO® (nivolumab), in combination with YERVOY® (ipilimumab), is indicated for the treatment of adult and pediatric patients 12 years and older with unresectable or metastatic melanoma.
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.

Other Immune-Mediated Adverse Reactions
The following clinically significant immune-mediated adverse reactions occurred at an incidence of <1% (unless otherwise noted) in patients who received OPDIVO monotherapy or OPDIVO in combination with YERVOY or were reported with the use of other PD-1/PD-L1 blocking antibodies. Severe or fatal cases have been reported for some of these adverse reactions: cardiac/vascular: myocarditis, pericarditis, vasculitis; nervous system: meningitis, encephalitis, myelitis and demyelination, myasthenic syndrome/myasthenia gravis (including exacerbation), Guillain-Barré syndrome, nerve paresis, autoimmune neuropathy; ocular: uveitis, iritis, and other ocular inflammatory toxicities can occur; gastrointestinal: pancreatitis to include increases in serum amylase and lipase levels, gastritis, duodenitis; musculoskeletal and connective tissue: myositis/polymyositis, rhabdomyolysis, and associated sequelae including renal failure, arthritis, polymyalgia rheumatica; endocrine: hypoparathyroidism; other (hematologic/immune): hemolytic anemia, aplastic anemia, hemophagocytic lymphohistiocytosis (HLH), systemic inflammatory response syndrome, histiocytic necrotizing lymphadenitis (Kikuchi lymphadenitis), sarcoidosis, immune thrombocytopenic purpura, solid organ transplant rejection, other transplant (including corneal graft) rejection.
In addition to the immune-mediated adverse reactions listed above, across clinical trials of YERVOY monotherapy or in combination with OPDIVO, the following clinically significant immune-mediated adverse reactions, some with fatal outcome, occurred in <1% of patients unless otherwise specified: nervous system: autoimmune neuropathy (2%), myasthenic syndrome/myasthenia gravis, motor dysfunction; cardiovascular: angiopathy, temporal arteritis; ocular: blepharitis, episcleritis, orbital myositis, scleritis; gastrointestinal: pancreatitis (1.3%); other (hematologic/immune): conjunctivitis, cytopenias (2.5%), eosinophilia (2.1%), erythema multiforme, hypersensitivity vasculitis, neurosensory hypoacusis, psoriasis.
Some ocular IMAR cases can be associated with retinal detachment. Various grades of visual impairment, including blindness, can occur. If uveitis occurs in combination with other immune- mediated adverse reactions, consider a Vogt-Koyanagi-Harada–like syndrome, which has been observed in patients receiving OPDIVO and YERVOY, as this may require treatment with systemic corticosteroids to reduce the risk of permanent vision loss.
Infusion-Related Reactions
OPDIVO and YERVOY can cause severe infusion-related reactions. Discontinue OPDIVO and YERVOY in patients with severe (Grade 3) or life-threatening (Grade 4) infusion-related reactions. Interrupt or slow the rate of infusion in patients with mild (Grade 1) or moderate (Grade 2) infusion-related reactions. In patients receiving OPDIVO monotherapy as a 60-minute infusion, infusion-related reactions occurred in 6.4% (127/1994) of patients. In a separate trial in which patients received OPDIVO monotherapy as a 60-minute infusion or a 30- minute infusion, infusion-related reactions occurred in 2.2% (8/368) and 2.7% (10/369) of patients, respectively. Additionally, 0.5% (2/368) and 1.4% (5/369) of patients, respectively, experienced adverse reactions within 48 hours of infusion that led to dose delay, permanent discontinuation or withholding of OPDIVO. In melanoma patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg every 3 weeks, infusion-related reactions occurred in 2.5% (10/407) of patients.
Complications of Allogeneic Hematopoietic Stem Cell Transplantation
Fatal and other serious complications can occur in patients who receive allogeneic hematopoietic stem cell transplantation (HSCT) before or after being treated with OPDIVO or YERVOY. Transplant-related complications include hyperacute graft-versus-host-disease (GVHD), acute GVHD, chronic GVHD, hepatic veno-occlusive disease (VOD) after reduced intensity conditioning, and steroid-requiring febrile syndrome (without an identified infectious cause). These complications may occur despite intervening therapy between OPDIVO or YERVOY and allogeneic HSCT.
Follow patients closely for evidence of transplant-related complications and intervene promptly. Consider the benefit versus risks of treatment with OPDIVO and YERVOY prior to or after an allogeneic HSCT.
Embryo-Fetal Toxicity
Based on its mechanism of action and findings from animal studies, OPDIVO and YERVOY can cause fetal harm when administered to a pregnant woman. The effects of YERVOY are likely to be greater during the second and third trimesters of pregnancy. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with OPDIVO and YERVOY and for at least 5 months after the last dose.
Increased Mortality in Patients with Multiple Myeloma when OPDIVO is Added to a Thalidomide Analogue and Dexamethasone
In randomized clinical trials in patients with multiple myeloma, the addition of OPDIVO to a thalidomide analogue plus dexamethasone resulted in increased mortality. Treatment of patients with multiple myeloma with a PD-1 or PD-L1 blocking antibody in combination with a thalidomide analogue plus dexamethasone is not recommended outside of controlled clinical trials.
Lactation
There are no data on the presence of OPDIVO or YERVOY in human milk, the effects on the breastfed child, or the effects on milk production. Because of the potential for serious adverse reactions in breastfed children, advise women not to breastfeed during treatment and for 5 months after the last dose.
Serious Adverse Reactions
In Checkmate 067, serious adverse reactions (74% and 44%), adverse reactions leading to permanent discontinuation (47% and 18%) or to dosing delays (58% and 36%), and Grade 3 or 4 adverse reactions (72% and 51%) all occurred more frequently in the OPDIVO plus YERVOY arm (n=313) relative to the OPDIVO arm (n=313).

Other Immune-Mediated Adverse Reactions
The following clinically significant IMARs occurred at an incidence of <1% (unless otherwise noted) in patients who received Opdualag or were reported with the use of other PD-1/PD-L1 blocking antibodies. Severe or fatal cases have been reported for some of these adverse reactions: Cardiac/Vascular: pericarditis, vasculitis; Nervous System: meningitis, encephalitis, myelitis and demyelination, myasthenic syndrome/myasthenia gravis (including exacerbation), Guillain-Barré syndrome, nerve paresis, autoimmune neuropathy; Ocular: uveitis, iritis, and other ocular inflammatory toxicities can occur. Some cases can be associated with retinal detachment. Various grades of visual impairment, including blindness, can occur. If uveitis occurs in combination with other IMARs, consider a Vogt-Koyanagi-Harada–like syndrome, as this may require treatment with systemic steroids to reduce the risk of permanent vision loss; Gastrointestinal: pancreatitis including increases in serum amylase and lipase levels, gastritis, duodenitis; Musculoskeletal and Connective Tissue: myositis/polymyositis, rhabdomyolysis (and associated sequelae including renal failure), arthritis, polymyalgia rheumatica; Endocrine: hypoparathyroidism; Other (Hematologic/Immune): hemolytic anemia, aplastic anemia, hemophagocytic lymphohistiocytosis, systemic inflammatory response syndrome, histiocytic necrotizing lymphadenitis (Kikuchi lymphadenitis), sarcoidosis, immune thrombocytopenic purpura, solid organ transplant rejection, other transplant (including corneal graft) rejection.
Infusion-Related Reactions
Opdualag can cause severe infusion-related reactions. Discontinue Opdualag in patients with severe or life- threatening infusion-related reactions. Interrupt or slow the rate of infusion in patients with mild to moderate infusion-related reactions. In patients who received Opdualag as a 60-minute intravenous infusion, infusion-related reactions occurred in 7% (23/355) of patients.
Complications of Allogeneic Hematopoietic Stem Cell Transplantation (HSCT)
Fatal and other serious complications can occur in patients who receive allogeneic hematopoietic stem cell transplantation (HSCT) before or after being treated with a PD-1/PD-L1 receptor blocking antibody. Transplant-related complications include hyperacute graft-versus-host disease (GVHD), acute GVHD, chronic GVHD, hepatic veno-occlusive disease after reduced intensity conditioning, and steroid-requiring febrile syndrome (without an identified infectious cause). These complications may occur despite intervening therapy between PD-1/PD-L1 blockade and allogeneic HSCT.
Follow patients closely for evidence of transplant-related complications and intervene promptly. Consider the benefit versus risks of treatment with a PD-1/PD-L1 receptor blocking antibody prior to or after an allogeneic HSCT.
Embryo-Fetal Toxicity
Based on its mechanism of action and data from animal studies, Opdualag can cause 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 Opdualag and for at least 5 months after the last dose of Opdualag.
Lactation
There are no data on the presence of Opdualag in human milk, the effects on the breastfed child, or the effect 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.
