- Cutaneous lesions should be evaluated as non-target lesions
- Performance status:
- For adult patients: Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0 or 1
- For pediatric patients: Karnofsky performance status ≥70 (patients ≥16 years) or Lansky performance status ≥70 (patients ≤16 years)
- Anticipated life expectancy of at least 3 months
Who cannot join
- Uveal melanoma
- Ongoing or recent (within 2 years) evidence of an autoimmune disease that required systemic treatment with immunosuppressive agents. The following are non-exclusionary: vitiligo, childhood asthma that has resolved, residual hypothyroidism that requires only hormone replacement, psoriasis not requiring systemic treatment.
- Uncontrolled infection with human immunodeficiency virus (HIV), hepatitis B (HBV) or hepatitis C virus (HCV) infection; or diagnosis of immunodeficiency that is related to, or results in chronic infection
- Unknown BRAF V600 mutation status as described in the protocol
- Systemic immune suppression:
- Use of immunosuppressive doses of corticosteroids (>10mg of prednisone per day or equivalent) within 14 days of the first dose of study medication. Physiologic replacement doses are allowed up to and including 10mg of prednisone/day or equivalent. Inhaled or topical steroids are permitted, if they are not for treatment of an autoimmune disorder.
Show all 16Show fewer
- Other clinically relevant forms of systemic immune suppression
- Treatment with other anti-cancer therapy including immuno- therapy, chemotherapy, major surgery or biological therapy within 21 days prior to the first dose of trial treatment. Adjuvant hormonotherapy used for breast cancer or other hormone-sensitive cancers in long term remission is allowed.
- History or current evidence of significant (CTCAE Grade ≥2) local or systemic infection (e. g., cellulitis, pneumonia, septicemia) requiring systemic antibiotic treatment within 14 days prior to the first dose of trial medication.
- Active or untreated brain metastases or spinal cord compression. Patients with leptomeningeal disease are excluded. Patients with known brain metastases are eligible if they:
- Received radiotherapy or another appropriate standard therapy for the brain metastases,
- Have neurologically returned to baseline (except for residual signs and symptoms related to the CNS treatment) for at least 14 days prior to enrollment
- Did not require immunosuppressive doses of corticosteroids therapy (>10mg of prednisone per day or equivalent) in the 14 days prior to enrollment
- Are asymptomatic with a single untreated brain metastasis <10 mm in size
- Participants with a history of myocarditis.

About this study
Official title: A Phase 3 Trial of Fianlimab (REGN3767, Anti-LAG-3) + Cemiplimab Versus Pembrolizumab in Patients With Previously Untreated Unresectable Locally Advanced or Metastatic Melanoma
This study is researching an experimental drug called REGN3767, also known as fianlimab (R3767), when combined with another medication called REGN2810, also known as cemiplimab (each individually called a "study drug" or called "study drugs" when combined).
The study is focused on patients with a type of skin cancer known as melanoma. The aims of the study are to see how effective the combination of fianlimab and cemiplimab are in treating the melanoma skin cancer, in comparison with a medication, pembrolizumab, approved for the treatment of melanoma skin cancer in adults, and to observe any similarities, or differences, in how the study drugs work in adolescent participants compared with adult participants.

The study is looking at several other research questions, including:
- What side effects may happen from receiving the study drugs
- How much study drug is in the blood at different times
- Whether the body makes antibodies against the study drugs (which could make the drugs less effective or could lead to side effects). Antibodies are proteins that are naturally found in the blood stream that fight infections.
- How administering the study drugs might improve quality of life
- Conditions
- Melanoma
- Being tested
- Fianlimab, Cemiplimab, Pembrolizumab, Placebo

Patient-reported outcomes (PROs) as measured by European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30)
EORTC-QLQ-C30 is a 30-item participant self-report questionnaire composed of both multi-item and single scales, including a global health status/quality of life (GHS/QoL) scale. Participants rate items on a four-point scale, with 1 as "not at all" and 4 as "very much." A change of 5 - 10 points is considered a small change. A change of 10 - 20 points is considered a moderate change.
Measured: Up to 90 days post last dose, approximately 6 years
PROs as measured by EQ-5D-5L
The EQ-5D-5L consists of EQ-5D descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. Overall scores range from 0 to 1, with low scores representing a higher level of dysfunction.
Measured: Up to 90 days post last dose, approximately 6 years
PROs as measured by Functional Assessment of Cancer Therapy melanoma (FACTM) (melanoma subscale only)
The FACTM is a melanoma-specific quality of life questionnaire that is composed of items from the Functional Assessment of Cancer Therapy-General (FACT-G). The FACTM is scored on a 5 point Likert-scale: "Not at all", "A little bit", "Somewhat", "Quite a bit", and "Very much.". A Higher score represents higher Health Related Quality of Life (HRQoL).
Measured: Up to 90 days post last dose, approximately 6 years
PROs as measured by Patient Global Impression of Severity (PGIS)
The PGIS is a single 1-item questionnaire designed to assess participant's overall impression of disease severity at a given point in time by using a 4-point Likert scale that ranges from (1) = "none (no symptoms)" to (4) = "severe".
Measured: Up to 21 days post last dose, approximately 6 years
PROs as measured by Patient Global Impression of Change (PGIC)
The PGIC is a single-item questionnaire designed to assess the participant's overall sense of whether there has been a change since starting treatment as rated on a 5-point Likert scale anchored by (1) "much better" to (5) "much worse", with (4) = "no change"
Measured: Up to 21 days post last dose, approximately 6 years
Change in physical functioning per EORTC QLQ-C30
EORTC-QLQ-C30 is a 30-item subject self-report questionnaire composed of both multi-item and single scales, including a global health status/quality of life (GHS/QoL) scale. Participants rate items on a four-point scale, with 1 as "not at all" and 4 as "very much." A change of 5 - 10 points is considered a small change. A change of 10 - 20 points is considered a moderate change.
Measured: Baseline to Week 25

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study is researching an experimental drug called REGN3767, also known as fianlimab (R3767), when combined with another medication called REGN2810, also known as cemiplimab (each individually called a "study drug" or called "study drugs" when combined).
The study is focused on patients with a type of skin cancer known as melanoma. The aims of the study are to see how effective the combination of fianlimab and cemiplimab are in treating the melanoma skin cancer, in comparison with a medication, pembrolizumab, approved for the treatment of melanoma skin cancer in adults, and to observe any similarities, or differences, in how the study drugs work in adolescent participants compared with adult participants.
The study is looking at several other research questions, including:
- What side effects may happen from receiving the study drugs
- How much study drug is in the blood at different times
- Whether the body makes antibodies against the study drugs (which could make the drugs less effective or could lead to side effects). Antibodies are proteins that are naturally found in the blood stream that fight infections.
- How administering the study drugs might improve quality of life
