Clinical Trial Summary

The goal of the Lead-in phase of the study is to evaluate the safety, efficacy, pharmacokinetics (PK) and determine recommended dose for expansion (RDE) of NKT2152 in combination with palbociclib (Doublet) and with palbociclib and sasanlimab (Triplet) in subjects with advanced or metastatic clear cell renal cell carcinoma (ccRCC) who received prior therapy. The goal of the Expansion phase of the study is to evaluate the safety, efficacy, PK at the selected RDE and identify the RP2D for NKT2152 in combination with palbociclib (Doublet) and with palbociclib and sasanlimab (Triplet) in subjects with advanced or metastatic clear cell renal cell carcinoma (ccRCC) who received prior therapy.

Description:

This is a Phase 2 open-label, multicenter, global study of NKT2152. This study is designed as two phases: a Lead-in phase and an Expansion phase. Patients must be 18 years or older, with advanced or metastatic clear cell renal cell carcinoma (ccRCC). Eligible patients must have progressed or relapsed after at least 1 prior anti-vascular endothelial growth factor (VEGF)/VEGF receptor (VEGFR) systemic therapy and 1 immune checkpoint inhibitor (ICI) for advanced or metastatic ccRCC alone or in combination.

The Lead-in phase is designed as a dose escalation phase to evaluate the safety, efficacy, pharmacokinetics (PK) and determine recommended dose for expansion (RDE) of NKT2152 in combination with palbociclib and sasanlimab in advanced or metastatic ccRCC patients who received prior therapy.

The subsequent Expansion phase will evaluate the safety, efficacy, PK at the selected RDE and identify the RP2D for NKT2152 in combination with palbociclib and sasanlimab in advanced or metastatic ccRCC patients who received prior therapy.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants with Dose Limiting Toxicity (DLT) events during the DLT monitoring period (first 28 days of dosing) in the Lead-in Phase	DLTs graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 5 .0.	28 days
Primary	Objective Response Rate (ORR) determined by the Investigator	ORR defined as the percentage of participants with a confirmed complete response (CR) or partial response (PR) based on Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.	1 years
Secondary	Progression-free survival (PFS)	PFS defined as the time from the date the participant started study drug to the date the participant experiences an event of disease progression or death.	2 years
Secondary	Duration of Response (DOR)	Duration of overall response is defined as the time from the date of first documented CR or PR, assessed by investigator and based on RECIST v. 1.1, to the documented date of progressive disease (PD) or death, whichever occurred first.	1 years
Secondary	Time to Response (TTR)	TTR is defined as the time from first dose to the first documented CR or PR which is subsequently confirmed.	1 years
Secondary	Overall Survival (OS)	OS defined as the time from the date the participant started study drug to death for any reason.	2 years
