A Study of (Neo)Adjuvant V940 and Pembrolizumab in Cutaneous Squamous Cell Carcinoma (V940-007)
Purpose
This is a two-part (Phase 2/Phase 3) study of V940, an individualized neoantigen therapy (INT), plus pembrolizumab in participants with locally resectable advanced cutaneous squamous cell carcinoma (LA cSCC). Phase 2 has three arms V940 plus pembrolizumab given as neoadjuvant and adjuvant treatment with standard of care (SOC), standard of care (surgical resection with/without adjuvant radiation therapy (RT) only at investigator's discretion) and pembrolizumab monotherapy given as neoadjuvant and adjuvant treatment with SOC. This phase will assess the safety and efficacy of V940 in combination with pembrolizumab as neoadjuvant and adjuvant therapy in participants with resectable LA cSCC as compared to standard of care SOC only. The primary hypothesis is that V940 plus pembrolizumab with SOC is superior to SOC only with respect to event free survival (EFS) as assessed by the investigator. Phase 3 expansion will be determined by prespecified Go-No-Go decision in which 412 additional participants will be randomized to V940 plus pembrolizumab with SOC and SOC only, without changing the inclusion/exclusion criteria for the additional enrollment or study endpoints.

Must have recovered from all radiation-related toxicities prior to randomization and not have had radiation pneumonitis - Has received an investigational agent or has used an investigational device within 4 weeks prior to study intervention administration - Has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior the first dose of study medication - Has a known additional malignancy that is progressing or has required active treatment within the past 2 years - History of chronic lymphocytic leukemia (CLL) - History of central nervous system (CNS) metastases and/or carcinomatous meningitis - Has severe hypersensitivity (≥Grade 3) to either V940 or pembrolizumab and/or any of its excipients - Has an active autoimmune disease that has required systemic treatment in the past 2 years. Replacement therapy (eg, thyroxine, insulin, or physiologic corticosteroid) is allowed - Has a history of (noninfectious) pneumonitis/interstitial lung disease that required steroids or has current pneumonitis/interstitial lung disease - Has an active infection requiring systemic therapy - Has HIV with a history of Kaposi's sarcoma and/or Multicentric Castleman's Disease - Has concurrent active Hepatitis B (defined as HBsAg positive and/or detectable HBV DNA) and Hepatitis C virus (defined as anti-HCV Ab positive and detectable HCV RNA) infection - Has had a myocardial infarction within 6 months of randomization - Has a history of allogeneic tissue/solid organ transplant - Has not adequately recovered from major surgery or have ongoing surgical complications

- Interventional
- Allocation
- Randomized
- Intervention Model
- Parallel Assignment
- Intervention Model Description
- In the Phase 2 of the study design, approximately 600 participants will be randomly assigned into 3 arms in an approximate 5:5:2 ratio (250 to V940 plus pembrolizumab with SOC, 250 participants to SOC only, and 100 participants to pembrolizumab monotherapy with SOC). If the decision is made to expand the study to Phase 3, the 600 participants enrolled in Phase 2 will keep their originally assigned study intervention arms in the Phase 3 Expansion, and 412 new participants will be enrolled and randomly assigned in a 1:1 ratio to receive treatment with either V940 plus pembrolizumab with SOC or SOC only. New participants will not be randomized into the pembrolizumab monotherapy with SOC arm during the Phase 3 Expansion.
