A Trial to Learn if Fianlimab and Cemiplimab Are Safe and Work Better than Anti-PD1 Alone in Adult Participants With Resectable Stage 3 or 4 Melanoma

Phase 2/3
Recruiting
Conditions
Melanoma
Registration Number
2022-502825-17-00
Lead Sponsor
Regeneron Pharmaceuticals Inc.
Brief Summary

Phase 2: To compare the treatment effect of the combination of fianlimab and cemiplimab to cemiplimab alone as peri-operative therapy in patients with resectable melanoma, as measured by pathological complete response (pCR) rate assessed by local pathological review, in order to inform (along with the totality of data from other fianlimab studies) the dose of fianlimab to use in combination with cemiplimab for the Phase 3 part of the study.

Phase 3: To assess the Event-free survival (EFS) for the combination of fianlimab and cemiplimab vs pembrolizumab alone as peri-operative therapy in patients with resectable melanoma.

Inclusion Criteria

All patients must be either stage III (IIIB, IIIC, IIID) or stage IV (M1a, M1b, M1c) per American Joint Committee on Cancer (AJCC) 8th edition (Amin 2017) and have histologically confirmed cutaneous melanoma that is deemed completely surgically resectable in order to be eligible as described in the protocol.

Patients with stage III melanoma must have clinically detectable disease that is confirmed as malignant on the pathology report. The pathology report must be reviewed, signed and dated by the investigator; this process will be confirmed during the interactive voice response system (IVRS) process as described in the protocol.

Patients must be candidates for full resection with curative intent and must be able to be surgically rendered free of disease with negative margins on resected specimens at surgery. The treatment plan including date of surgery must be documented by the investigator prior to randomization.

All patients must undergo full disease staging through a complete physical examination and imaging studies within 4 weeks prior to randomization. Imaging must include a computer tomography (CT) scan of the chest, abdomen, pelvis (if the primary tumor is on the head/neck then include a CT scan of head/neck), and all known sites of previously resected disease (if applicable) and brain magnetic resonance imaging (MRI) (or brain CT with contrast allowed if MRI is contraindicated).

Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0 or 1

Exclusion Criteria

Primary 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.

Patients must not have received any prior systemic anti-cancer therapy for melanoma. Prior radiotherapy for melanoma is allowed if not given to a target lesion or, if given to a target lesion, there is pathological evidence of disease progression in the same lesion.

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 as described in the protocol.

Use of immunosuppressive doses of corticosteroids (>=10mg of prednisone per day or equivalent) within 14 days of the first dose of study medication as described in the protocol.

Treatment with any anti-cancer therapy for malignancies other than melanoma, including immuno- therapy, chemotherapy, radiotherapy, or biological therapy in the 5 years prior to randomization as described in the protocol.

Participants with a history of myocarditis.

History or current evidence of significant (CTCAE grade ≥2) local or systemic infection (e. g., cellulitis, pneumonia, septicemia) requiring systemic antibiotic treatment within 2 weeks prior to the first dose of trial medication.
