Clinical Trial Summary

A Phase 1b/2 Study of Repotrectinib in Combination with Other Anticancer Therapies for the Treatment of Subjects with KRAS-Mutant Advanced Solid Tumors (TRIDENT-2)

Description:

Phase 1 Dose Escalation: To evaluate tolerability of repotrectinib at increasing dose levels in combination with other anticancer therapies for the treatment of subjects with locally advanced or metastatic KRAS-mutant solid tumors Phase 2 Efficacy Evaluation: Investigate the anti-tumor efficacy and safety of repotrectinib in combination with other anticancer therapies for the treatment of patients with locally advanced or metastatic KRAS-mutant solid tumors.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants With Dose Limiting Toxicities	Number of participants with first cycle DLTs to determine Mean Tolderable Dose (MTD) and/or RP2D.; A DLT is defined as an adverse event (AE) or abnormal laboratory value assessed as unrelated to disease progression, intercurrent illness, or concomitant medications that meets the criteria defined in each subprotocol.; The MTD is defined as the highest dose level of repotrectinib given in combination with other anticancer therapy observed to cause a DLT in fewer than 33% of the treated subjects in the first treatment cycle (i.e., Cycle 1).	From initial dose to end of first cycle of treatment, approximately 28 days
Secondary	Overall Response Rate (ORR) Assessed the Investigator Using RECIST v1.1.	The ORR will be defined as the percentage of participants with a confirmed complete response (CR) or partial response (PR). A confirmed response is a response that persists on a repeat imaging performed at least 4 weeks after initial documentation of response. Participants with a confirmed objective response (CR or PR) will be referred to as responders.; Radiographic confirmation of objective tumor response (CR or PR) or disease progression will be based on RECIST v1.1. The ORR will be reported as the percentage of responders by RECIST v1.1 along with the corresponding two-sided 95% Clopper-Pearson exact CI.; Complete Response (CR) = Disappearance of all target lesions Partial Response (PR) = >=30% decrease in the sum diameters of target lesions.	From screening to end of treatment approximately 10 months
Secondary	Cmax of Repotrectinib	Cmax is defined as maximum plasma concentration of the drug.	At Cycle 1 Day 1 and Cycle 1 Day 22
Secondary	Tmax of Repotrecitinib	Tmax is defined is the time to maximum plasma concentration	At Cycle 1 Day 1 and Cycle 1 Day 22
Secondary	AUC 0-24 of Repotrecitinib	Area under the plasma concentration time-curve. AUC from time 0 to 24 hours after dose.	At Cycle 1 Day 1 and Cycle 1 Day 22
Secondary	Cmax of Trametinib	Cmax is defined as maximum plasma concentration of the drug.	At Cycle 1 Day 1 and Cycle 1 Day 22
Secondary	Tmax of Trametinib	Tmax is defined is the time to maximum plasma concentration	At Cycle 1 Day 1 and Cycle 1 Day 22
Secondary	AUC 0-24 of Trametinib	Area under the plasma concentration time-curve. AUC from time 0 to 24 hours after dose.	At Cycle 1 Day 1 and Cycle 1 Day 22
