Brief Summary

The main objective will be to estimate the disease free survival (DFS) of patients with resectable head and neck mucosal melanomas treated by neo-adjuvant anti-PD1 (in combination or not with lenvatinib) followed by surgery, radiotherapy and maintenance immunotherapy in order to compare it to historical DFS results of this kind of patients treated by surgery and radiotherapy. Our primary end-point will be disease-free survival at 2 years

Study Groups

Cohort A

The cohort A (Pembrolizumab only) will be opened in a first study step. Anti-PD1 antibody will be used (pembrolizumab, Merck®) intravenously at a dose of 200 mg every 3 weeks (4 injections maximum over 12 weeks), monotherapy

Group Type: EXPERIMENTAL

Pembrolizumab

Intervention Type: DRUG

Neo-adjuvant therapy :

• Anti-PD1 antibody will be used (pembrolizumab, Merck®) intravenously at a dose of 200 mg every 3 weeks. The patient will receive 4 injections maximum over 12 weeks. According to the investigator's opinion, the 4th injection might be cancelled in order to perform surgery from week 10 and not after week 13.
• Tumor response will be assessed 2 weeks after the last injection both clinically and radiologically (by CT-scan and MRI).

Maintenance therapy by anti-PD1 antibody (pembrolizumab, Merck®) will be then used intravenously at a dose of 200 mg every 3 weeks for a maximum period of one year, starting one month after the end of radiotherapy.

Surgery

Intervention Type: PROCEDURE

Surgery will be performed (endoscopically if possible) 3 weeks after the last injection, at the earliest week 10 and at the latest at week 13 and will be completed by radiotherapy using IMRT technology according to the International and European Rhinologic Societies guidelines.

IMRT

Intervention Type: RADIATION

Surgery will be performed (endoscopically if possible) 3 weeks after the last injection, at the earliest week 10 and at the latest at week 13 and will be completed by radiotherapy using IMRT technology according to the International and European Rhinologic Societies guidelines.

Cohort B

Up to 26 evaluable patients will be treated in the cohort B (Pembrolizumab with Lenvatinib) if they do not have any contraindication for receiving lenvatinib treatment, otherwise they will be treated in the cohort A if slots are available. In the cohort B, the neo-adjuvant anti-PD1 immunotherapy will be combined with orally lenvatinib at a daily dose of 20 mg for 6 weeks started on the day of the first anti-PD1 dose.

12. Has known history of, or any evidence of active, non-infectious pneumonitis.

13. Has an active infection requiring systemic therapy.

14. Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator.

15. Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.

16. Is pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the trial, starting with the pre-screening or screening visit through 120 days after the last dose of trial treatment.
