Brain imaging is not required at inclusion if asymptomatic. 10. Has severe hypersensitivity (=Grade 3) to pembrolizumab and/or lenvatinib and/or any of their excipients. 11.Has active autoimmune disease that has required systemic treatment in the past 2 years. 12.Has a history of (non-infectious) pneumonitis that required steroids or has current pneumonitis. 13.Has an active infection requiring systemic therapy. 14.Has a known history of Human Immunodeficiency Virus (HIV) infection. HIV testing is not required at allocation. 15.Has a known history of Hepatitis B (defined as Hepatitis B surface antigen [HBsAg] reactive) or known active Hepatitis C virus (defined as HCV RNA [qualitative] is detected) infection. Note: no testing for Hepatitis B and Hepatitis C is required unless mandated by local health authority. 16.Has a known history of active TB (Bacillus Tuberculosis). 17.Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the subject’s participation for the full duration of the study 18.Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial. 19.Is pregnant or breastfeeding or expecting to conceive. 20.Has had an allogenic tissue/solid organ transplant. 21.Concurrent or recent (less than 1 week prior inclusion) immunosuppressive médications. 22.Uncontrolled blood pressure. 23.Electrolyte abnormalities that have not been corrected as assessed by the investigator. 24.Significant cardiovascular impairment. 25.Bleeding or thrombotic disorders or subjects at risk for severe hemorrhage. 26.Subjects having > 1+ proteinuria on urine dipstick testing unless a 24-hour urine collection for quantitative assessment indicates that the urine protein is <1 g/24 hours. 27.Subjects who have not recovered adequately from any toxicity from other anti-cancer treatment regimens and/or complications from major surgery prior to starting therapy.

| Main Objective: Primary objective is to evaluate the progression-free survival (PFS) after 27 weeks of treatment as assessed by the investigator using the RECIST v1.1. Because clinical benefit of pembrolizumab is expected to be influenced by prior treatment by Tebentafusp (better response to Pembrolizumab when previously treated by Tebentafusp), two independent cohorts will be conducted: cohort 1 with Tebentafusp-naive patients, and cohort 2 patients previously treated with Tebentafusp. In each cohort, we hypothesize that combining pembrolizumab with lenvatinib in metastatic UM will target essential cellular oncogenic pathways while normalizing tumor vascularization, leading to an increase infiltration of the tumor by immune cells and a better control of the disease assessed by the Response Evaluation Criteria in Solid Tumors (RECIST 1.1) at nine cycles of treatment (third tumor evaluations (27 weeks). Combination effect is expected to be the same in each cohort. ;Secondary Objective: [1]To evaluate PFS over the entire follow-up [2]To evaluate the overall survival (OS) for the combination [3]To evaluate the objective response rate (ORR) according to RECIST 1.1 as assessed by the investigator [4]To evaluate the safety and tolerability for the combination [5]To compare the mean change from baseline in the global health status/quality of life (QoL) [6]To evaluate the 27-weeks PFS per Modified RECIST 1.1 for Immune-based Therapeutics (iRECIST) as assessed by the investigator [7]To explore biomarkers of response (exploratory) ;Primary end point(s): The progression-free survival (PFS) will be assessed after 9 cycles (i.e. 27 weeks +/- 2 weeks) using the RECIST criteria version 1.1, based on investigator assessment. PFS will be estimated as a crude rate at 27 weeks (+/- 2 weeks, i.e. 14 days) after the start of treatment when patients will be followed at least between 25 and 29 weeks after the start of treatment. Will be considered progression events: objective clinical | — |
Secondary
| Measure | Time frame |

| Secondary end point(s): [1]PFS is defined as the time from the date of treatment start until the date of first objective clinical or radiological disease progression (RECIST 1.1) or death. Patients alive and without progression at the date of last contact will be censored at this date. [2]OS is defined as the time from the start of treatment until the date of death due to any cause. Patients alive at the date of last contact will be censored at this date.
