The trial will include 8 cohorts of patients, with each cohort considered as a single-arm; all patients enrolled will be treated with regorafenib at a dose of 90 mg orally once daily, on days 1 to 21 of a 28 cycle in combination with tislelizumab 300 mg intravenously day 1 (of a 28 day cycle).

REFIT-MSS is a non-randomized, multicenter, open-label, multi-cohort, 2-stage, phase II trial to evaluate the efficacy and safety of regorafenib in combination with tislelizumab (referred as Rego-Tisle) in adult patients with select advance, previously treated, Mismatch Repair-Proficient/Microsatellite (pMMR/MSS) stable solid cancers.

The multi-cohort design will allow for the examination of 8 separate cohorts of different cancers to determine whether further examination may be warranted in the individual indications.

This is a non-randomized, multicenter, open-label, multi-cohort, phase II trial to evaluate the efficacy and safety of Rego-Tisle in adult patients with solid tumors that are advanced, pretreated and refractory to standard therapy. Approximately 322 evaluable patients (between 15 and 82 per cohort) in around 65 sites will be enrolled to power the trial efficiently to measure the primary endpoint, Progression Free Survival at 6 months (PFS-6).

Patients should have at least one measurable lesion per Response Evaluation Criteria in Solid Tumors guidelines version 1.1 (RECIST 1.1), an Eastern Cooperative Oncology Group Performance Scale (ECOG PS) 0-1, and adequate organ function.

The trial will include patients who had been diagnosed with a histologically or cytologically confirmed solid tumor belonging to any of the types in the cohorts to be enrolled. To be eligible, patient must meet the criteria for tumor type, stage and prior anti-cancer therapy according to inclusion criteria.

The trial will include 8 cohorts of patients. Each cohort is considered as a single-arm activity-estimating sub-study with PFS-6 as the primary endpoint. A strong primary endpoint signal seen in a cohort may allow for expansion of the cohort, independently of the status of the other cohorts. Similarly, a cohort may be opened and/or closed for enrollment independently of others.

Regorafenib With Tislelizumab in Patients With Selected Mismatch Repair-Proficient/Microsatellite Stable Cancers

An Open-label, Phase II, Multi-cohort, 2-stage Trial to Evaluate the Efficacy and Safety of Regorafenib in Combination With Tislelizumab in Patients With Selected Mismatch Repair-Proficient/Microsatellite Stable Pretreated Solid Cancers

PFS-6 is defined as the proportion of patients who remained free of PFS event (disease progression or death) at 6 months from the date of enrollment.

Defined as the proportion of patients who have a complete response (CR) or partial response (PR) based on investigator assessment.

Defined as the proportion of patients who have CR, PR, or stable disease (SD) according to RECIST 1.1, as per investigator assessment.

Defined as the time (in months) from first documentation of response (PR or CR) to progressive disease (PD) or death, based on investigator assessment or death, in patients who had best overall response of CR or PR.

Defined as as the ratio of time to progression (TTP) with the nth line (TTP(n)) of therapy to the TTP(n)(-1) with the n-1th line.

Defined as time from date of enrollment to date of death due to any cause. Median OS, OS at 6 months (OS-6) and OS at 12 months (OS-12) will be evaluated.

In metastatic castration-resistant prostate cancer (mCRPC) cohort only; defined as the time from the date of enrollment to the date of PSA progression based on Prostate Cancer Clinical Trials Working Group 3 (PCWG3) criteria
