Phase Ib Study of TNO155 in Combination With Spartalizumab or Ribociclib in Selected Malignancies

Colorectal Cancer Clinical Trial

Official title: A Phase Ib, Open-label, Multi-center Study to Characterize the Safety, Tolerability, and Preliminary Efficacy of TNO155 in Combination With Spartalizumab or Ribociclib in Selected Malignancies

Status Terminated

Clinical Trial Summary

This study was a Phase Ib, multi-center, open-label study of TNO155 in combination with spartalizumab or ribociclib with a dose escalation part followed by a dose expansion part in adult subjects with advanced solid tumors. These two treatment arms enrolled subjects in parallel to characterize the safety, tolerability, PK, PD and preliminary antitumor activity. The study treatment was administered until the subject experienced unacceptable toxicity, progressive disease, and/or had treatment discontinued at the discretion of the Investigator or the subject, or due to withdrawal of consent.

Clinical Trial Description

Rationale The purpose of this study was to evaluate the safety, tolerability, and preliminary efficacy of the combination of TNO155 with spartalizumab and of TNO155 with ribociclib, and to identify dosing regimens for further study. Data from preclinical models have demonstrated anti-tumor activity for the combinations of TNO155 with spartalizumab and of TNO155 with ribociclib that is superior to the activity observed with each of the drugs as single agents. These data suggest that these combinations may provide clinical benefit to patients with advanced malignancies. Study Design This study was a Phase Ib, multi-center, open-label study with a dose escalation part followed by a dose expansion part in adult subjects with advanced solid tumors to characterize the safety and tolerability TNO155 in combination with spartalizumab and of TNO155 in combination with ribociclib and to identify the MTD and/or recommended regimen (dose and schedule) for each combination. The study treatment was administered until the subject experienced unacceptable toxicity, progressive disease, and/or had treatment discontinued at the discretion of the Investigator or the subject, or due to withdrawal of consent. Objectives Primary objective: To characterize the safety and tolerability TNO155 in combination with spartalizumab and of TNO155 in combination with ribociclib, and to identify the MTD and/or recommended regimen (dose and schedule) for each combination. Secondary objectives: - To characterize the pharmacokinetic (PK) profile of TNO155, spartalizumab and ribociclib when administered as a combination of TNO155 plus spartalizumab or of TNO155 plus ribociclib. - To evaluate the preliminary anti-tumor activity of TNO155 in combination with spartalizumab and of TNO155 in combination with ribociclib. ;
