Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Signed informed consent must be obtained prior to participation in the study.
2. Age ≥ 18 years. For Japan only: written consent is necessary both from the patient and his/her legal representative if he/she is under the age of 20 years.
3. ECOG (Eastern Cooperative Oncology Group) performance status ≤ 1.
4. Dose escalation part: Patients with advanced solid tumors, with evaluable disease as determined by RECIST version 1.1, and fit into one of the following groups:

a. For TNO155 plus spartalizumab combination: i. Advanced EGFR WT, ALK WT NSCLC, after progression on or intolerance to platinum-containing combination chemotherapy and after progression on anti-PD-1 or anti-PD-L1 therapy.

ii. Advanced HNSCC or esophageal SCC, after progression on or intolerance to platinum-containing combination chemotherapy.

iii. Advanced CRC, after progression on or intolerance to all standard-of-care (SOC) therapy per local guidelines.

b. For TNO155 plus ribociclib combination: Advanced solid malignancies with the exception of CRC or GIST, after progression on or intolerance to all SOC therapy per local guidelines. The exclusion of CRC applies only as of Protocol Amendment 4.
5. Dose expansion part: Patients with advanced solid tumors, with at least one measurable lesion as determined by RECIST version 1.1, who fit into one of the following groups:

a. For TNO155 plus spartalizumab combination: i. Advanced EGFR WT, ALK WT, KRAS G12C NSCLC after progression on or intolerance to platinum-containing combination chemotherapy and after progression on anti-PD-1 or anti-PD-L1 therapy.

ii. Advanced EGFR WT, ALK WT, KRAS WT NSCLC, after progression on or intolerance to platinum-containing combination chemotherapy and after progression on anti-PD-1 or anti-PD-L1 therapy.

iii. Advanced HNSCC, after progression on or intolerance to, platinum-containing combination chemotherapy.

b. For TNO155 plus ribociclib combination: i. Advanced EGFR WT, ALK WT, KRAS WT NSCLC, after progression on or intolerance to platinum-containing chemotherapy and anti-PD-1 or anti-PD-L1 therapy ii. Advanced HNSCC, after progression on or intolerance to all SOC per local guidelines
6. Patients with NSCLC whose tumors harbor genomic aberrations for which SOC targeted therapies exist and are locally approved and available must have had progression on or after, or intolerance to, the SOC targeted therapy/therapies as indicated
