Brief Summary

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 RDEs based on objective response rate (ORR) and determine the preliminary recommended Phase 2 dose (RP2D).

Detailed Description

Inclusion Criteria:

- Must have a pathologically confirmed unresectable advanced or metastatic solid tumor listed below with documented disease progression on last standard treatment. Patients must also be refractory to, or intolerant of existing therapy(ies) known to provide clinical benefit for their condition.

Dose Escalation:

1. Ovarian cancer with CCNE1 amplification

2. Endometrial cancer with CCNE1 amplification

3. Gastric cancer, gastroesophageal junction (GEJ) or esophageal adenocarcinoma with CCNE1 amplification

4. Small cell lung cancer (SCLC)

5. Triple-negative breast cancer (TNBC; human epidermal growth factor receptor 2, estrogen receptor and progesterone receptor negative)

6. Pathologically confirmed HR+ (includes estrogen-receptor or progesterone-receptor) and human epidermal growth factor receptor 2 negative (HER2-) breast cancer (BrCa; must have progressed following treatment with a CDK4/6 inhibitor, and is not suitable for endocrine therapy)

Dose Expansion:

Part 2A: Pathologically confirmed HR+ and HER2- breast cancer which must have progressed following treatment with a CDK4/6 inhibitor, are not suitable for further endocrine therapy and have had no more than one line of prior systemic chemotherapy in the metastatic setting.

Part 2B: Platinum resistant or refractory ovarian cancer (defined as recurrence ≤6 months after completing platinum-based regimen) with progression on at least one platinum containing therapy, with CCNE1 amplification as determined by NGS by local liquid or tissue test.

Part 2C: Advanced unresectable or metastatic gastric, GEJ or esophageal adenocarcinoma with progression on at least one systemic therapy, with CCNE1 amplification as determined by NGS by local liquid or tissue test.

* History of uveitis, retinopathy or other clinically significant retinal disease

* Active or chronic corneal disorders, other active ocular conditions requiring ongoing therapy, or any clinically significant corneal disease

* Major surgery within 2 months or minor surgery within 10 days before the first dose of NKT3964.

* Has known human immunodeficiency virus (HIV), active hepatitis B or C infection

* Prior treatment with a selective or nonselective CDK2 inhibitor

* Childs-Pugh class B or C cirrhosis or any other clinically significant liver disorder

* Radiation therapy within 4 weeks prior to C1D1

Primary Outcome Measures
NameTimeMethod
Number of Participants with Dose Limiting Toxicity (DLT) events28 Days

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

Objective Response Rate (ORR)1 Year

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

Secondary Outcome Measures
NameTimeMethod
Progression-free survival (PFS)2 Year

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.

Duration of Response (DOR)2 Year

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.

Disease control rate1 Year

Disease control rate defined as CR + PR + stable disease \[SD\]

Overall Survival (OS)2 Year

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

Time to Response (TTR)1 Year

TTR is defined as the time from first dose to the first documented CR or PR which is subsequently confirmed.

Number of Participants with Adverse Events2 Year

An adverse event (AE) is defined as any untoward medical occurrence in a patient and which does not necessarily have a causal relationship with this treatment. The investigator assessed the relationship of each event to the use of study drug as either probably related, possibly related, probably not related or not related.
