Treatment for resectable head and neck mucosal melanoma using immunotherapy

Phase II Multicentric Study: Efficacy Evaluation of Neoadjuvant Treatment Associated With Maintenance Therapy by Anti-PD1 Immunotherapy on Disease-free-survival (DFS) in Patients With Resectable Head and Neck Mucosal Melanoma

This study is testing if a new immunotherapy treatment can help people with resectable head and neck mucosal melanoma live longer without the disease after surgery and other treatments.

• Sex: All
• Sponsor: Gustave Roussy, Cancer Campus, Grand Paris (Academic / other)

What this trial studies

This clinical trial aims to evaluate the disease-free survival (DFS) of patients with resectable head and neck mucosal melanomas who receive neoadjuvant anti-PD1 immunotherapy, potentially in combination with lenvatinib, followed by surgery, radiotherapy, and maintenance immunotherapy. The primary endpoint is to assess DFS at two years and compare the results with historical data from similar patients treated with surgery and radiotherapy alone. The study will involve a series of interventions including pembrolizumab, surgery, and intensity-modulated radiotherapy (IMRT).

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with resectable head and neck mucosal melanoma who are eligible for surgical treatment and adjuvant radiotherapy.

Not a fit: Patients with unresectable melanoma or those who cannot undergo surgery or radiotherapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve disease-free survival rates for patients with head and neck mucosal melanoma.

How similar studies have performed: While there have been studies on immunotherapy for melanoma, this specific combination approach is novel and has not been extensively tested.

    For the cohort B, patients must met the following additional criteria :
14. Not having any contraindication for lenvatinib treatment

2. Has a metastatic disease.
3. Has a non resectable melanoma.
4. Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy (except topical or inhaled steroids) or any other form of immunosuppressive therapy within 2 weeks prior to the first dose of trial treatment.
5. Has a known history of active TB (Bacillus Tuberculosis)
6. Hypersensitivity to pembrolizumab or any of its excipients.
7. Has had a prior anti-cancer monoclonal antibody (mAb) within 4 weeks prior to D1 of study treatment or who has not recovered (i.e., ≤ Grade 1 or at baseline) from adverse events due to agents administered more than 4 weeks earlier.
8. Has had prior chemotherapy, targeted small molecule therapy, or radiation therapy within 4 weeks or 5 half-life times (whatever the shorter) prior to study Day 1 or who has not recovered (i.e., ≤ Grade 1 or at baseline) from adverse events due to a previously administered agent.

   * Note: Subjects with ≤ Grade 2 neuropathy are an exception to this criterion and may qualify for the study.
   * Note: If subject received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy.
9. Has a known additional malignancy that is progressing or requires active treatment. Exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the skin that has undergone potentially curative therapy or in situ cervical cancer.
10. Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Subjects with previously treated brain metastases may participate provided they are stable (without evidence of progression by imaging for at least four weeks prior to the first dose of trial treatment and any neurologic symptoms have returned to baseline), have no evidence of new or enlarging brain metastases, and are not using steroids for at least 7 days prior to trial treatment. This exception does not include carcinomatous meningitis which is excluded regardless of clinical stability.
11. Has active autoimmune and/or immune mediated inflammatory disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (eg., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
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.

The degree of tumor invasion/infiltration of major blood vessels (e.g. carotid artery) should be considered because of the potential risk of severe hemorrhage associated with tumor shrinkage/necrosis following lenvatinib therapy
29. 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.
