研究概览
简要总结
The purpose of this study is to assess the safety and efficacy of pembrolizumab (MK-3475) combined with lenvatinib (MK-7902/E7080) compared to pembrolizumab alone (with placebo for lenvatinib) as first-line treatment in adults with no prior systemic therapy for their advanced melanoma.
The primary study hypotheses are that: 1) The combination of pembrolizumab and lenvatinib is superior to pembrolizumab and placebo as assessed by Progression-free Survival (PFS) per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1), and 2) The combination of pembrolizumab and lenvatinib is superior to pembrolizumab and placebo as assessed by Overall Survival (OS). For this study, RECIST 1.1 has been modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ.
详细描述
As of 03-April-2023 active participants, investigator, and sponsor personnel or delegate(s) involved in the treatment administration or clinical evaluation of the participants will be unblinded.

入选标准
- •Has histologically or cytologically confirmed melanoma.
- •Has unresectable Stage III or Stage IV melanoma, as per American Joint Committee on Cancer guidelines, not amenable to local therapy.
- •Has been untreated for advanced or metastatic disease except as follows:
- •Proto-oncogene B-Raf (BRAF) V600 mutation-positive melanoma may have received standard of care targeted therapy as first-line therapy for advanced or metastatic disease. Participants that do not have a BRAF V600 mutation but did receive BRAF or BRAF/mitogen-activated extracellular signal-regulated kinase 1/2 Inhibitor (MEKi) therapy are eligible to participate in this study after discussion with the medical monitor.
- •Prior adjuvant or neoadjuvant therapy, with targeted therapy or immunotherapy (such as anti-cytotoxic T-lymphocyte-associated protein 4 [CTLA-4], anti-programmed cell death 1 [anti-PD-1] therapy or interferon) will only be permitted if relapse did not occur during active treatment or within 6 months of treatment discontinuation.
- •Have documentation of BRAF V600-activating mutation status or consent to BRAF V600 mutation testing during the Screening period (participants with BRAF mutation-positive melanoma as well as BRAF wild-type or unknown are eligible).
- •Has an Eastern Cooperative Oncology Group (ECOG) performance status 0 to
- •Has the presence of ≥1 measurable lesion by computed tomography (CT) or magnetic resonance imaging (MRI) per RECIST 1.
- •Provides a tumor biopsy. Participants must submit tumor sample during Screening for confirmation of adequacy of tumor tissue at a central pathology laboratory. Participants who do not submit a tumor tissue sample will not be randomized. The tumor biopsy may not be obtained from a lone target lesion. Confirmation of presence of tumor tissue is not required prior to randomization.
- •Has resolution of toxic effect(s) of the most recent prior therapy to Grade 1 or less (except alopecia). If participant received major surgery or radiation therapy of >30 Gray (Gy), they must have recovered from the toxicity and/or complications from the intervention.
- •Male participants must agree to use contraception during the treatment period and for at least 7 days after the last dose of study treatment and refrain from donating sperm during this period. Please note that 7 days after lenvatinib/placebo is stopped, if the participant is on pembrolizumab only, no male contraception measures are needed. Contraception use by men should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies. If the contraception requirements in the local label for any of the study interventions is more stringent than the requirements above, the local label requirements are to be followed.
- •Female participants must not be pregnant, not breastfeeding, and ≥1 of the following conditions applies:
- •Not a woman of childbearing potential (WOCBP). OR

时间窗: Up to approximately 34 months
PFS is defined as the time from date of randomization to the date of the first documentation of progressive disease (PD) or death from any cause, whichever occurs first. Per RECIST 1.1, PD is defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. Note: The appearance of one or more new lesions is also considered PD. For this study, RECIST 1.1 has been modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ. The final analysis for this outcome is presented here.
