A Non-randomized, Open-label Phase Ib Study of SUnitinib Alternating With REgorafenib in Patients With Metastatic and/or Unresectable Gastrointestinal Stromal Tumors (GIST) Progressing After Prior Therapy With Tyrosine Kinase Inhibitors
In Brief
A Phase 1 clinical trial evaluating Sunitinib and Regorafenib for Gastrointestinal Stromal Tumor. Completed, enrolled 14 participants across 1 site.
Detailed Summary
The purpose of this research study is to determine the safety and tolerability of sunitinib alternating with regorafenib in participants with advanced gastrointestinal stromal tumor GIST, if the standard approved therapies (imatinib, sunitinib and regorafenib) have failed to control the disease. Additionally, this study seeks to determine the highest dose that can be given safely for this combination of drugs.

Timeline
Interventions
Intervention Description: 3 days of once daily sunitinib alternating with 4 days of once daily regorafenib throughout each 28 day cycle. The starting dose level (level 1) is sunitinib 37.5 mg/d and regorafenib 120 mg/d, and doses will be escalated in subsequent cohorts following a classical 3+3 design up to sunitinib 50 mg/d and regorafenib 160 mg/d or until maximum tolerable dosage (MTD) and recommended phase II dose (RP2D) is determined. Number of Cycles: until progression or unacceptable toxicity develops.
