Spots Global Cancer Trial Database for A Study of Dazostinag as Single Agent and Dazostinag in Combination With Pembrolizumab in Adults With Advanced or Metastatic Solid Tumors

Study Description

Brief Summary: The main aim of this study is to check if people with advanced solid tumors have side effects from dazostinag, and to check how much dazostinag they can receive without getting significant side effects from it when given alone and in combination with pembrolizumab. The study will be conducted in two phases including a dose escalation phase and a dose expansion phase. In the dose escalation phase, escalating doses of dazostinag are being tested alone and in combination with pembrolizumab to treat participants who have advanced or metastatic solid tumors. In the dose expansion phase, dazostinag will be studied with pembrolizumab with or without chemotherapy in participants with untreated metastatic or recurrent, unresectable squamous cell carcinoma of head and neck (SCCHN) and in combination with pembrolizumab in third-line or later recurrent locally advanced or metastatic microsatellite instability-high/mismatch repair deficient (MSI-H/dMMR) and third-line recurrent locally advanced or metastatic microsatellite stable/mismatch repair proficient (MSS/pMMR) colorectal cancer (CRC).

Detailed Description: The drug being tested in this study is called dazostinag. Dazostinag is being tested to treat people who have advanced or metastatic solid tumors. The study will enroll approximately 368 participants. Part 1 consists of an initial Safety Lead-in to Dose Escalation Phase; Part 2 and Part 3 compose the Expansion Phase in 2 specific indications namely, previously untreated metastatic or recurrent, unresectable SCCHN (Part 2) and third-line or later recurrent locally advanced or metastatic MSI-H/dMMR and third-line recurrent locally advanced or metastatic MSS/pMMR CRC (Part 3). Participants will be assigned to the following treatment groups in the respective Phases of the study: * Part 1 (Dose Escalation Phase): Safety Lead-in + Dazostinag single agent (SA) \[Part 1A\] Dazostinag 0.1 milligram (mg) in the Safety Lead-in followed by Dazostinag as escalating doses (0.2 mg and above) in Part 1A * Part 1B (Combination Dose Escalation Phase): Dazostinag as escalating doses (0.2 mg and above) + Pembrolizumab * Japan Safety Lead-in: Dazostinag SA 5.0 mg in the Safety Lead-in+ Pembrolizumab. Additional dose levels of Dazostinag (such as 3.5 mg or 7.0 mg and higher) in combination with pembrolizumab may be explored during the Japan safety lead-in considering recommended dose for expansion (RDE1) as 5.0 mg and dose optimization. Once a safe dose is recommended from Part 1, participants of select advanced or metastatic solid tumors will receive dazostinag in below defined cohorts in the expansion phase: * Part 2A (SCCHN Combined Positive Score \[CPS\] ≥ 1 Dose Expansion Phase): Dazostinag + Pembrolizumab\* * Part 2B (SCCHN Dose Expansion Phase): Dazostinag + Pembrolizumab + Chemotherapy * Part 3A (Expansion Phase in CRC): Dazostinag + Pembrolizumab in MSI-H/dMMR CRC * Part 3B (Expansion Phase in CRC): Dazostinag + Pembrolizumab in MSS/pMMR CRC\* \*Dose optimization will be performed in either Part 2A SCCHN or Part 3B CRC. This multi-center trial will be conducted worldwide. The overall time to participate in this study is 62.9 months. Participants will make multiple visits to the clinic, including 30 days after last dose of study drug for a follow-up assessment. Participants in Parts 2 and 3 will be followed for survival for up to 12 months after the last dose of study drug.
