About this trial

The goal of the Dose Escalation phase of the study is to evaluate the safety, tolerability, pharmacokinetics (PK) and preliminary anti-tumor activity to determine the preliminary recommended dose for expansion (RDE) of NKT3964 in adults with advanced or metastatic solid tumors. The goal of the Expansion phase of the study is to evaluate the preliminary anti-tumor activity of NKT3964 at the RDE based on objective response rate (ORR) and determine the preliminary recommended Phase 2 dose (RP2D).

Trial outcomes

Primary outcomes

1

Number of Participants with Dose Limiting Toxicity (DLT) events

DLTs graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 5.0

Time frame
28 Days
2

Objective Response Rate (ORR)

ORR defined as the percentage of participants with a confirmed complete response (CR) or partial response (PR) by Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1) as determined by the Investigator

Time frame
1 Year

Secondary outcomes

1

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.

Time frame
2 Year
2

Duration of Response (DOR)

Duration of overall response is defined as the time from the date of first confirmed CR or PR, assessed by investigator and based on RECIST v. 1.1, to the documented date of progressive disease (PD) including clinical progression, or death due to any cause, or the start of subsequent anticancer therapy, whichever occurred first.

Time frame
2 Year
3

Disease control rate

Disease control rate defined as CR + PR + stable disease \[SD\] for at least 8 weeks

Time frame
1 Year
4

Overall Survival (OS)

OS defined as the time from the date the participant started study drug to death for any reason.

Time frame
2 Year
