Abstract:
Melanoma is a highly lethal type of skin cancer. Although an early diagnosis, in combination with surgery for nonmetastatic melanomas, significantly increases the probability of survival, there are no efficacious treatments for metastatic melanoma. Nivolumab and relatlimab are monoclonal antibodies that selectively interact with and block the proteins programmed cell death protein 1 (PD-1) and lymphocyte activation protein 3 (LAG-3), respectively, and thus, their activation by their cognate ligands. The combination of these immunotherapy drugs was approved in 2022 by the United States Food and Drug Administration (FDA) for the treatment of melanoma. Data from clinical trials indicated that, compared to nivolumab monotherapy, nivolumab and relatlimab produced more than a 2-fold median increase in progression-free survival (PFS) and a higher response rate in melanoma patients. This is an important finding as the response of patients to immunotherapies is limited due to dose-limiting toxicities and secondary drug resistance. This review article will discuss the pathogenesis of melanoma and the pharmacology of nivolumab and relatlimab. In addition, we will provide i) a summary of the anticancer drugs that inhibit LAG-3 and PD-1 in cancer patients and ii) our perspective about the use of nivolumab in combination with relatlimab to treat melanoma.
Insights
Nivolumab and relatlimab combination therapy offers a significant improvement in progression-free survival for melanoma patients. This immunotherapy approach shows promise for treating advanced melanoma, overcoming limitations of prior treatments.
Area of Science:
- Oncology
- Immunology
- Dermatology
Background:
- Melanoma is a deadly skin cancer with limited treatment options for metastatic stages.
- Early diagnosis and surgery improve survival for nonmetastatic melanoma.
- Immunotherapy resistance and toxicity pose challenges in melanoma treatment.
Approach:
- Review of melanoma pathogenesis and the pharmacology of nivolumab and relatlimab.
- Summary of anti-lymphocyte activation protein 3 (LAG-3) and anti-programmed cell death protein 1 (PD-1) drugs in cancer.
- Discussion on the combination of nivolumab and relatlimab for melanoma treatment.
Key Points:
- Nivolumab (anti-PD-1) and relatlimab (anti-LAG-3) are novel immunotherapy agents.
- The combination of nivolumab and relatlimab was FDA-approved in 2022 for melanoma.
- Clinical trials show over a 2-fold increase in progression-free survival (PFS) with the combination compared to nivolumab alone.
Conclusions:
- The nivolumab-relatlimab combination represents a significant advancement in metastatic melanoma treatment.
- This dual immunotherapy may overcome resistance mechanisms and improve patient outcomes.
- Further research and clinical application of PD-1 and LAG-3 inhibitors are warranted.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
