Summary

This is an open, single arm, multicenter phase 2 trial in which BO-112 will be administered intratumorally in combination with intravenous pembrolizumab in patients with liver metastasis from colorectal, gastric or gastroesophageal junction cancers. The objective is to reverse the primary resistance that a subgroup of patients from these tumors having microsatellite stability present to the PD-1 inhibitors. Treatment will be administered every 3 weeks, with the exception of the first cycle, in which BO-112 will be also administered on D8, for up to 2 years.

The primary objective is overall response rate based on RECIST 1.1 and safety, specifically referred to treatment emergent adverse events (TEAEs) with severity ≥ Grade 3 related to the study treatment (NCI-CTCAE v 5.0). The secondary endpoints include other efficacy endpoints (duration of response, disease control rate, progression-free survival, overall survival at 6 months, all based on RECIST 1.1, and overall response rate based on a specific tumor assessment criteria to evaluate the response to immunotherapies, IRECIST) and safety, in this case considering the number and proportion of subjects with treatment TEAEs (any grade) . In addition, the changes in the tumor microenvironment induced by the injection of BO-112 will be also evaluated as exploratory endpoints.

Conditions

Interventions

PROCEDURE

Hepatic Biopsy

In this trial a biopsy from the hepatic lesion to be injected will be mandatory on C1D1 and C2D1, prior to the BO-112 administration. On the same timepoints, a biopsy from a non-hepatic, non-injected lesion will be optional.

DRUG

BO-112 with pembrolizumab

BO-112 was administered in the liver metastasis at the dose of 1mg (1.2 mL) in combination with intravenous pembrolizumab given at the fixed dose of 200 mg, every 3 weeks for up to 35 cycles (2 years). During the first cycle, BO-112 was administered on D1 and D8.
