About

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.

Full 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.

172 participants in 4 patient groups

Lead-in Doublet combination
Experimental group
Description:
Lead-in Doublet assesses safety of oral dosing NKT2152 at increasing dosage levels in combination with palbociclib to determine a recommended dose for expansion (RDE).
Treatment:
Drug: palbociclib
Drug: NKT2152
Lead-in Triplet combination
Experimental group
Description:
Lead-in Triplet assesses the safety of two doses of NKT2152 identified in the Doublet arm (RDE and RDE-1) by orally dosing ccRCC patients with NKT2152 in combination with palbociclib and sasanlimab
Treatment:
Other: sasanlimab
Drug: palbociclib
Drug: NKT2152
Expansion Doublet combination
Experimental group
Description:
Subjects randomized to Arm 1 will receive the Doublet combination (NKT2152 in combination with palbociclib) to provide an assessment of anti-tumor activity and to determine the RP2D.
Treatment:
Drug: palbociclib
Drug: NKT2152
Expansion Triplet combination
Experimental group
Description:
Subjects randomized to Arm 2 will receive the Triplet therapy (NKT2152 in combination with palbociclib and sasanlimab) to provide an assessment of anti-tumor activity and to determine the RP2D.
Treatment:
Other: sasanlimab
Drug: palbociclib
Drug: NKT2152
