Gastrointestinal Stromal Tumors Clinical Landscape Report 2026: Trials, Readouts and White Space
Turn fragmented clinical intelligence into a decision-ready landscape. This report was assembled with PatSnap MCP Servers for Clinical Trials, Drug & Asset, and Company & Deal Intelligence. Explore the PatSnap MCP Marketplace to reproduce the workflow in your own AI research stack.
Data snapshot: 16 July 2026. This report is a strategic research view, not medical advice. Trial status and timing can change; confirm records before making development or investment decisions.
Executive view
Gastrointestinal Stromal Tumors remains an active clinical development field. The competitive center of gravity is moving toward biomarker-defined populations, rational combinations, earlier treatment lines and evidence that can survive active-comparator scrutiny. The PatSnap evidence set used here contains 260 matched trial records and 546 indexed result records before the decision-focused sample below was selected.
How PatSnap MCP built this report
The workflow used Clinical Trials MCP search to define the landscape, then clinical_trial_fetch to retrieve trial design, phase, status, sponsor, geography, endpoints and timing. It separately called clinical_trial_result_fetch for indexed readouts. Drug & Asset drug_fetch supplied target and global development status, while Company & Deal Intelligence organization_fetch supplied sponsor context. This keeps trial-, asset- and company-level claims distinct and traceable.
Trial landscape table
| Trial | Asset / intervention | Phase / status | Sponsor | Geography | Primary endpoint | Expected readout |
|---|---|---|---|---|---|---|
| NCT07700758 | Belzutifan | Phase 2; Not yet recruiting | Merck Sharp & Dohme LLC | Geography not listed | Number of Participants Who Experience One or More Adverse Events (AEs) (Up to approximately 5 years); Number of Participants Who Discontinue Study Intervention Due to an AE (Up to approximately 5 years) | 2034-01-02 |
| JPRN-jRCT1030260304 | Intervention not normalized | Phase 3; 募集中 | Ethicon, Inc. | Japan | 術後12カ月時点における腹壁瘢痕ヘルニアの発生割合; Incidence of incisional abdominal wall hernia at 12 months postoperatively | 2030-11-30 |
| NCT07697248 | Intervention not normalized | Not Applicable; Recruiting | Life Raft Group, Inc. | United States | Overall survival (From the date of registry enrollment until death from any cause, assessed…); Progression Free Survival (From the date of registry enrollment until the first documented disease…) | 2099-12-31 |
| NCT07689201 | Velzatinib | Phase 2; Not yet recruiting | GSK Plc | Geography not listed | Confirmed objective response rate (ORR) (Up to 67 weeks) | 2027-12-13 |
The table is designed for competitive decisions: endpoint selection, geographic reach and readout timing appear beside phase and sponsor. Phase alone does not reveal evidence maturity; a small study may answer a near-term biomarker question while a large pivotal program can leave a multi-year readout gap.
What indexed results say
- StrateGIST 3: A randomized, phase 3 study of velzatinib (IDRX-42) versus sunitinib in patients with advanced gastrointestinal stromal tumors after imatinib therapy. (Phase 3): the indexed record reports ORR(2nd-line) = 33.0 % ( 19.5 - 48.0).
- Standard-dose ripretinib plus sunitinib versus ripretinib dose escalation in advanced GIST after progression on four prior therapies: Preliminary results of a multicenter cohort study. (Not Applicable): the indexed record reports AE(grade ≥3) = no grade ≥3 adverse events reported; AE(grade ≥3) = no grade ≥3 adverse events reported.
- Ripretinib as preoperative therapy in patients with potentially resectable advanced gastrointestinal stromal tumors after imatinib failure: Final analysis of a prospective, multicenter study. (Phase 2): the indexed record reports NED Rate = 92.9 %.
Cross-trial comparisons require caution. Population, prior therapy, baseline risk, endpoint definition, follow-up and analysis set can all change the apparent signal. The strategic value lies in identifying what each readout resolves—and which uncertainty remains.

Asset and sponsor context
PatSnap Drug & Asset records add mechanism and global development status for the sampled programs, including Belzutifan (Approved; HIF-2α), Velzatinib (Phase 3; TYK2 x c-Kit). Company & Deal Intelligence records identify sponsor context for Merck Sharp & Dohme LLC, Ethicon, Inc., Life Raft Group, Inc., GSK Plc (GSK). Together, those layers show whether a study sits inside a scaled portfolio, an emerging specialist strategy or an academic development path.
Where the white space is
- Prospective biomarker thresholds that predict benefit rather than simply confirm target presence.
- Randomized sequencing evidence after prior targeted therapy, immunotherapy or antibody–drug conjugates.
- Endpoints that connect response depth with durability, quality of life and overall survival.
- Geographically broader development programs with harmonized molecular testing.
Strategic implications
For sponsors, differentiation is more credible when the evidence package resolves a known decision gap: an active comparator, a better-defined responder population, a safer or easier delivery model, a clinically meaningful outcome, or a defensible sequencing strategy. Business-development teams can use the same landscape to separate crowded mechanisms from differentiated evidence architectures. Investors should track endpoint maturity and operational feasibility alongside nominal phase.
What to monitor next
Track status changes, protocol amendments, primary-completion dates, newly indexed results, ownership changes and multinational expansion. Re-run the MCP queries on a schedule and compare deltas. Pay particular attention when a program moves from a surrogate endpoint to a clinical outcome or when a specialist sponsor adds a scaled development partner.
Bottom line
Gastrointestinal Stromal Tumors has meaningful clinical activity and equally meaningful evidence gaps. A useful landscape connects trial design, results, mechanism and sponsor rather than listing studies in isolation.
