Phase 2
Conditions
Solid Tumor
Lymphoma
Interventions
Registration Number
NCT03544723
Lead Sponsor
MultiVir, Inc.
Brief Summary

This is a single arm Phase 2 study of the combination of adenoviral p53 (Ad-p53) gene therapy administered intra-tumorally with approved immune checkpoint inhibitors in patients with recurrent or metastatic cancers. Comparison will be made to historical data. General safety and efficacy using RECIST 1.1 and Immune-Related Response Criteria as well as ECOG performance will be utilized.

Detailed Description

This is a Phase 2 study of the combination of Ad-p53 administered intra-tumorally in combination with physician's choice of FDA approved immune checkpoint inhibitor therapy in patients with recurrent or metastatic cancers. This is a safety and efficacy study with a single cohort, consisting of the combination of Ad-p53 and infusions of immune checkpoint inhibitors. Immune checkpoint inhibitor treatments will be administered in accordance with FDA package inserts. Comparison will be made to historical data. General safety and preliminary efficacy will be determined using RECIST 1.1, ECOG status and Immune-Related Response Criteria. Biomarker testing of archival or fresh tissue is performed during the study. Enrollment will be up to 40 patients.

Primary Outcome Measures
NameTimeMethod
The primary efficacy endpoint is objective response rate (ORR)Change in tumor size at the end of Cycle 2 (each cycle is 28 days)

Objective response rate will be evaluated by RECIST 1.1

Safety assessments of adverse events per CTCAESigned Informed Consent through 30 Days following the final treatment

Safety evaluations will tabulate adverse events per CTCAE

Secondary Outcome Measures
NameTimeMethod
Preliminary assessment of Duration of Response (DoR) by RECIST 1.1Day 1 through end of study, approximately 2 years

RECIST 1.1 will be used to determine Duration of Response (DoR)

Preliminary assessment of progression free survival (PFS) by RECIST 1.1Day 1 through end of study, approximately 2 years

RECIST 1.1 will be used to determine progression free survival
