Trial Identification

Brief Title: Study of BO-112 With Pembrolizumab for Colorectal or Gastric/GEJ Cancer With Liver Metastasis

Official Title: Phase IIa Open-label Clinical Study of Intratumoural Administration of BO-112 in Combination With Pembrolizumab in Subjects With Liver Metastasis From Colorectal Cancer or Gastric/Gastro-oesophageal Junction Cancer

Study ID: NCT04508140

Study Description

Brief 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.

Detailed Description: The purpose of this Phase II study is to evaluate the safety, tolerability, antitumoural activity and systemic exposure of repeated IT administrations of BO-112 percutaneously injected into a hepatic metastatic lesion in combination with pembrolizumab administered intravenously. This is an open-label, non-comparative, 2-cohort study with a Simon's 2-stage design which will include up to 69 evaluable adult subjects with un resectable liver metastasis suitable for IT injection from CRC or GC/GEJ who are naive to anti-PD1/PDL1 therapy. Cohort A will consist of up to 26 subjects with metastatic CRC who have received at least 2 prior standard of care systemic anticancer therapies for advanced/metastatic disease. Bevacizumab may have been previously administrated. Prior Anti-EGFR drugs are mandatory if applicable depending on the RAS status. Cohort B will consist of up to 43 subjects with gastric or GC/GEJ who have received at least 1 prior standard of care systemic anticancer therapy for advanced/metastatic disease. Prior Her2 blockade will be mandatory in those patients with Her2 positive tumors. The aim of this study is to reverse the primary resistance that the subgroup of patients from these 2 cohorts who present microsatellite stability (MSS), in which data from previous clinical trials have demonstrate that the inhibition of PD-1 has no proven efficacy. For that purpose, the MSI status will be determined in the pre-treatment biopsy, done on C1D1, before the first BO-112 administration. Those patients with a MSI status will continue under study treatment but will be replaced and will not be considered for the efficacy assessment, only for the safety assessment. Those patients having a MSS status will be considered bot both assessments. The recommended dose for further clinical development of BO-112 is 1 mg administered in 1.7 mL volume, based on the data from the 112/2016-IT study, the fist-in-human trial with BO-112. The planned dose of pembrolizumab for this study is 200 mg. Study treatment will consist of BO-112 IT injections in combination with IV pembrolizumab infusions and will be administered in 3-week cycles. For each cycle, BO-112 IT injections will be administered after the pembrolizumab infusion, either the same day or within a period of up to 36 hours after the pembrolizumab infusion (for organisational feasibility at the site). On the first cycle, BO-112 will be administered on D1 and D8. The BO-112 IT injections will be administered by an interventional radiologist under ultrasound guidance, or occasional CT scan guidance, at the discretion of the interventional radiologist. Study treatment should continue as long as there is clinical benefit and it is tolerated, up to a maximum of approx. 2 years (corresponding to 35 treatment cycles).
