A Master Protocol to Evaluate DCC-3009 in Gastrointestinal Stromal Tumor (GIST)
- Registration Number
- NCT06630234
- Lead Sponsor
- Deciphera Pharmaceuticals, LLC
- Brief Summary
The purpose of this Phase 1/2 master protocol study is to evaluate if DCC-3009 is safe, tolerable and works effectively in the treatment of GIST. The study will use a modular approach with each module being defined according to therapy: DCC-3009 alone or DCC-3009 in combination with other anticancer therapies. Each module will be conducted in 2 parts: Part 1 (Dose Escalation) and Part 2 (Dose Expansion). Participants will be treated in 28-day treatment cycles with an estimated duration of up to 2 years.

Group Intervention Description DCC-3009 Module A DCC-3009 Participants will receive DCC-3009 in 28 day cycles in Module A Part 1 dose escalation and Part 2 dose expansion.
- Primary Outcome Measures
Name Time Method Number of Participants with Dose-Limiting Toxicities (DLT) (Part 1 Escalation) Cycle 1 (28 Days) DLTs assessed for each dose level.
Objective Response Rate (ORR) (Part 2 Expansion) Baseline to Progressive Disease (PD), Death due to Any Cause, or Start of New Antitumor Therapy (Estimated up to 24 months) ORR is the percentage of participants with confirmed complete response (CR) or confirmed partial response (PR) based on Modified Response Evaluation Criteria in Solid Tumors (mRECIST), v1.1.
- Secondary Outcome Measures
Name Time Method Objective Response Rate (ORR) (Part 1 Escalation) Baseline to Progressive Disease (PD), Death due to Any Cause, or Start of New Antitumor Therapy (Estimated up to 24 months) ORR is the percentage of participants with confirmed complete response (CR) or confirmed partial response (PR) based on mRECIST, v1.1.
Duration of Response (DOR) First Recorded CR or PR until PD or Death (Estimated up to 24 months) DOR for participants with confirmed CR or confirmed PR based on mRECIST, v1.1, defined as the time interval from the time that the measurement criteria are first met for CR or PR (whichever is first recorded) until the first date that the disease progression is objectively documented or death, whichever occurs first.
Progression-Free Survival (PFS) Initiation of Treatment to PD or Death (Estimated up to 24 months) PFS is the time from initiation of treatment until documented disease progression per mRECIST, v1.1, or death, whichever occurs first.
Overall Survival (OS) Initiation of Treatment to Death from Any Cause (Estimated up to 24 months) OS is the time from initiation of treatment to the date of death from any cause.
Pharmacokinetics (PK): Maximum observed plasma drug concentration (Cmax) Estimated up to 24 months Cmax
