Nemvaleukin Alfa Monotherapy and in Combination With Pembrolizumab in Patients With Advanced Cutaneous or Mucosal Melanoma - ARTISTRY-6

Inclusion Criteria

• •The patient must have the following tumor types:
• •Cohort 1: Patient has unresectable and/or metastatic cutaneous melanoma. No more than 5 patients with acral melanoma may enroll in this cohort.
• •Cohort 2: Patient has unresectable and/or metastatic mucosal melanoma.
• •Cohort 3: Patient has unresectable and/or metastatic cutaneous melanoma. Patients with acral melanoma may not enroll in this cohort.
• •Cohort 4: Patient has unresectable and/or metastatic cutaneous melanoma. No patients with mucosal or acral melanoma may enroll in this cohort.
• •\- The patient must have received previous treatment as follows: Cohorts 1 and 2: Patient has received anti-PD-\[L\]1 therapy with or without anti-CTLA-4 therapy, and less than or equal to one other prior regimen of systemic anti-neoplastic therapy (eg, targeted therapy, chemotherapy). Previous adjuvant and/or neoadjuvant therapy counts as one prior regimen. Patients have experienced objective response (partial response \[PR\] or CR; by RECIST 1.1 or iRECIST) or stable disease (SD; by RECIST 1.1 or iRECIST) as best overall response (BOR) to anti-PD-\[L\]1 therapy. Patients with confirmed progressive disease (by RECIST 1.1 or iRECIST) as best response may be included, if they received anti-PD-\[L\]1 therapy for a minimum of 12 weeks (eg, from first dose to last dose). Patients with BRAF mutations may or may not have received prior targeted therapy.
• •Cohort 3: Patients who have received anti-PD-\[L\]1 therapy with or without anti-CTLA-4 therapy or anti-lymphocyte-activation gene 3 (LAG-3) therapy, and ≤1 other prior regimen of systemic anti-neoplastic therapy (eg, targeted therapy, chemotherapy). Previous adjuvant and/or neoadjuvant therapy counts as 1 prior regimen. Patients must have experienced objective response (PR or CR by RECIST 1.1 or iRECIST) or stable disease (by RECIST 1.1 or iRECIST) as BOR to anti PD-\[L\]1 therapy. Patients with confirmed progressive disease (by RECIST 1.1 or iRECIST) as best response may be included, if they received anti-PD-\[L\]1 therapy for ≥12 weeks (from first dose to last dose). Patients with BRAF mutations may or may not have received prior targeted therapy.
• •Cohort 4: Patients must not have received prior systemic anticancer therapy for unresectable or metastatic melanoma. Prior adjuvant and/or neoadjuvant PD-\[L\]1 treatments are allowed if there is at least 6 months between the last dose and date of recurrence.
• •Cohorts 1, 2, and 3 - Patients who have received prior treatment with talimogene laherparepvec (TVEC) are allowed to enroll provided that last exposure to TVEC was ≥28 days prior to first exposure to nemvaleukin and that all injection-site reactions to TVEC have resolved. TVEC shall not be considered a prior regimen of systemic anti-neoplastic therapy, nor shall it be considered a systemic immunomodulatory agent.
• •Patients must have disease that is measurable based on RECIST 1.1., that has not recently been irradiated or used to collect a biopsy.
• •Cohorts 1 and 2 (required), Cohort 3 (optional), Cohort 4 (may be required, otherwise optional). Patient is willing to undergo a pretreatment tumor biopsy or provide qualifying archival tumor tissue.
• •Cohort 4 - Patients are required to have known tumor PD-\[L\]1 status determined by local testing using an approved assay. PD-\[L\]1 testing performed prior to enrolling on the study is acceptable if there was no intervening systemic anti-cancer therapy, and archival tissue may be used for testing provided the biopsy is ≤3 months old.
• •Patient has an Eastern Cooperative Oncology Group (ECOG) status of 0 or 1 and an estimated life expectancy of ≥3 months.
• •Additional criteria may apply.
