LUMINOS-103: A Basket Trial Evaluating the Safety and Efficacy of Lerapolturev (PVSRIPO) and Lerapolturev in Combination With Anti-PD-1/L1 Checkpoint Inhibitors in Patients With Advanced Solid Tumors
This is a Phase 1/2, open-label, multi-center, single arm basket study evaluating the administration of lerapolturev ± anti programmed cell death protein 1 (PD 1)/programmed death-ligand 1 (PD L1) monoclonal antibody (mAb) (which will be referred to throughout this protocol as "anti-PD-1/L1 therapy") therapy in adult patients with solid tumor cancers. Bladder Cancer and Head and Neck Squamous Cell Carcinoma have been selected as the first tumor specific cancers of interest for enrollment.
For each solid tumor cancer, a Phase 1 evaluation of the safety and tolerability of lerapolturev monotherapy intratumoral injections will be completed prior to initiation of enrollment in the Phase 2 portion of the study where the anti-tumor efficacy of lerapolturev in combination with anti PD 1/L1 therapy will be assessed. Bladder Cancer This section focuses on those aspects of the study design specific to patients with bladder cancer. Two cohorts of patients will be enrolled: Cohort A will include cisplatin refusal or ineligible patients with resectable MIBC being treated in the neoadjuvant setting and Cohort B will include patients with bladder cancer being treated in the 1st/2nd line unresectable/metastatic setting. The Phase 1 portion of the study (lerapolturev monotherapy) will only enroll patients from Cohort A. Once the Data Safety Monitoring Committee (DSMC) has evaluated the safety of the patients enrolled in the Phase 1 portion of the study and determined it is "safe to proceed", then the Phase 2 portion of the study (lerapolturev/pembrolizumab combination) will open. Approximately 6 patients will be enrolled in Phase 1 (Cohort A), and 50 patients will be enrolled in Phase 2 (25 patients in Cohort A and 25 patients in Cohort B). Head and Neck Squamous Cell Carcinoma This section focuses on those aspects of study design specific to patients with HNSCC. Two cohorts of patients will be enrolled in this portion of the study. Cohort C will include patients with resectable, locally advanced HNSCC (LA-HNSCC) being treated in the neoadjuvant setting and Cohort D will include patients with recurrent or metastatic (R/M) HNSCC being treated in the 1st line setting. The 6 patients to be enrolled in the Phase 1 portion of the study (lerapolturev monotherapy) may be composed of patients meeting the eligibility criteria for either Cohort C or Cohort D. Once the Data Safety Monitoring Committee (DSMC) has evaluated the safety of the patients enrolled in the Phase 1 portion of the study and determined it is "safe to proceed", then the Phase 2 portion of the study (lerapolturev/anti-PD-1/L1 combination) will open. Approximately 6 patients will be enrolled in Phase 1 (Cohort C and D), and 50 patients will be enrolled in Phase 2 (25 patients in Cohort C and 25 patients in Cohort D).
