1150-101

Details and patient eligibility

About

This study is to determine the maximum tolerated dose (MTD) and the recommended Phase 2 dose (RP2D) and to investigate the safety, pharmacokinetics (PK), pharmacodynamics, and preliminary antitumor activity of NDI-101150 given as monotherapy or in combination with pembrolizumab in adult patients with advanced solid tumors.

Full description

This is a multicenter, open-label, first-in-human, Phase 1/2 study.

The study will consist of 2 phases:

The Dose Escalation Phase: designed to evaluate the safety and tolerability of NDI-101150 as monotherapy (Arm 1) and in combination with pembrolizumab (Arm 2) in patients with advanced solid tumors. The Dose Expansion Phase: designed to evaluate the safety and efficacy of NDI-101150 as monotherapy (Arm 1) and in combination with pembrolizumab (Arm 2) in disease-specific dose expansion cohorts: gastric and gastroesophageal junction [GEJ] cancer, non-small cell lung cancer [NSCLC], and renal cell carcinoma [RCC].

Each phase of the study will consist of 3 periods:

A Screening period of up to 28 days during which patient eligibility will be reviewed and approved by the Sponsor. Treatment period that will extend from Cycle 1 Day 1 until progression of disease (PD), unacceptable toxicity, withdrawal of consent, start of a new systemic anticancer treatment, discontinuation of the patient by the Investigator, or termination of the study by the Sponsor. This will also include Safety Follow-up Visit 30 days [+3 days] after the last dose of investigational medicinal product. Post treatment Follow-up period which will continue until lost to follow-up, withdrawal of consent, or the End of the Study (whichever comes first).

Enrollment: 106 estimated patients

• Known additional malignancy that is active and/or in progression requiring treatment
• Unstable or severe uncontrolled medical condition (e.g., unstable cardiac function, unstable pulmonary condition, uncontrolled diabetes, thromboembolic event within the past 3 months) or any important medical or psychiatric illness or abnormal laboratory finding
• Unable to discontinue medications that are strong inducers or inhibitors of CYP3A4 and/or CYP2C8
• History of severe irAE that led to permanent discontinuation of prior immunotherapy
