Dublin, Oct. 14, 2026 (GLOBE NEWSWIRE) -- "Gastrointestinal Stromal Tumor (GIST) - Market Insight, Epidemiology, and Market Forecast - 2036" has been added to ResearchAndMarkets.com's offering.

The gastrointestinal stromal tumor (GIST) market is evolving as molecular diagnostics, targeted therapies and mutation-specific treatment strategies improve patient management. The report analyzes historical and forecasted GIST epidemiology, treatment practices, market size, therapy uptake, pricing, reimbursement and competitive dynamics across the seven major markets (7MM): the United States, Germany, Spain, Italy, France, the United Kingdom and Japan.

GISTs account for less than 1% of gastrointestinal tumors but represent the most common mesenchymal tumors of the gastrointestinal tract. Approximately 55-60% originate in the stomach, while 30-35% arise in the small intestine. Less common sites include the esophagus, colon and rectum. Rare primary tumors may also occur outside the gastrointestinal tract.

Patients are typically assessed for recurrence or progression risk using tumor size, mitotic index, anatomical location and mutation status. Molecular testing for KIT and PDGFRA mutations is central to treatment selection, with succinate dehydrogenase testing recommended for tumors without detectable KIT or PDGFRA alterations. Approximately 80% of cases are driven by KIT mutations, while 12-15% are classified as KIT/PDGFRA wild-type GIST. Fewer than 5% are associated with hereditary or syndromic conditions.

GIST Market Size and Forecast

• 2025 GIST market size: approximately USD XX million
• 2036 projected GIST market size: approximately USD XX million
• Expected growth during 2026-2036: XX% CAGR

The report provides a comprehensive GIST market forecast for 2022-2036, including patient population trends, therapy-specific revenue, market share, peak patient share, drug uptake and regional growth opportunities. Market expansion is expected to be supported by improving diagnosis, broader molecular testing, continued adoption of tyrosine kinase inhibitors (TKIs), regulatory incentives and the development of therapies targeting resistance mutations.

GIST Epidemiology and Patient Population

GIST can occur at any age but is most frequently diagnosed in older adults, with a median age of 65-69 years and a slight predominance among males. Up to 50% of patients may present with metastatic disease or multifocal tumor involvement at diagnosis.

In 2025, the United States recorded more than 5,600 incident GIST cases, representing the highest number among the 7MM. Estimates generally indicate 5,000-6,000 new US cases annually, and the incident population is expected to increase during the forecast period. Localized GIST remains the most commonly diagnosed stage.

Current GIST Treatment Landscape

Surgical resection remains the principal treatment for localized GIST. For advanced, metastatic or unresectable disease, targeted TKIs have replaced conventional chemotherapy as the main systemic treatment approach. Treatment decisions are increasingly guided by mutation status, previous therapy, resistance profile and disease stage.

Established treatment sequencing includes imatinib (GLEEVEC) in the first-line setting, sunitinib (SUTENT) in the second-line setting, regorafenib (STIVARGA) in the third-line setting and ripretinib (QINLOCK) in the fourth-line setting. Approximately 15-20% of patients demonstrate primary resistance to available therapies, underscoring the need for broader mutation coverage and alternative treatment strategies.

Ripretinib is an oral switch-control TKI that targets multiple initiating and resistance mutations in KIT and PDGFRA. It is approved for later-line advanced GIST and is also being evaluated in Phase III development as a second-line treatment. According to ONO Pharmaceutical's 2025-26 financial results, ripretinib sales increased by USD 80 million, or 50.6% year on year, to USD 239.5 million.

Avapritinib (AYVAKIT) is approved for adults with unresectable or metastatic GIST harboring PDGFRA exon 18 mutations, including D842V. Its approval established an important mutation-specific Option for a patient group historically associated with limited response to earlier TKIs. Larotrectinib (VITRAKVI) may also be relevant for rare GIST cases with actionable NTRK gene fusions.

Emerging GIST Therapies and Competitive Landscape

The GIST pipeline includes agents designed to address primary mutations, secondary resistance mutations and molecular heterogeneity. Leading companies include ONO Pharmaceutical, Sanofi, Blueprint Medicines Corporation, Bayer , Loxo Oncology, Cogent Biosciences, GSK, Sartar Therapeutics and Kumquat Biosciences.

• Bezuclastinib: Cogent Biosciences is developing this selective type I TKI for KIT activation loop mutations. In the Phase III PEAK trial, bezuclastinib plus sunitinib reduced the risk of progression or death by 50% compared with sunitinib alone. Median progression-free survival was 16.5 months versus 9.2 months. The US FDA accepted the New Drug Application under Priority Review, with a Target Action date of November 30, 2026.
• Velzatinib (IDRX-42/GSK6042981): GSK is developing this investigational TKI to Target clinically relevant primary and secondary KIT mutations. The therapy has received Fast Track Designation and Orphan Drug Designation from the US FDA. A first-line Phase III study is planned for 2026.
• SAR003: Sartar Therapeutics is advancing this investigational therapy for KIT-driven tumors. In September 2025, SAR003 received Orphan Drug Designation for GIST from both the FDA and EMA.

Late-stage candidates such as bezuclastinib and velzatinib are expected to increase competition during the latter half of the forecast period. Their commercial potential will depend on comparative efficacy, safety, mutation coverage, treatment-line positioning, regulatory outcomes, pricing and access.

Key GIST Market Growth Drivers

• Improved molecular diagnosis: Expanded KIT, PDGFRA and SDH testing is increasing diagnostic accuracy and supporting mutation-directed treatment selection.
• Advances in targeted therapy: Next -generation TKIs are being developed to overcome resistance and improve disease control across treatment lines.
• Regulatory support: Orphan Drug Designation, Fast Track Designation, Breakthrough Therapy Designation and Priority Review can accelerate development and regulatory assessment.
• Increasing treatment segmentation: Greater understanding of molecular subtypes is creating opportunities for precision oncology and biomarker-defined therapies.
• Growing clinical pipeline: Combination strategies and broad- Spectrum KIT inhibitors may expand the addressable GIST treatment market.

Unmet Needs in GIST Treatment

• Primary and acquired resistance to existing targeted therapies
• Drug-resistant tumor subclones and molecular heterogeneity
• Limited options for KIT/PDGFRA wild-type and SDH-deficient GIST
• Need for durable responses across multiple treatment lines
• Challenges in long-term disease monitoring and survivorship
• Access, affordability and reimbursement barriers for high-cost therapies

GIST Drug Uptake, Pricing and Market Access

Drug uptake during 2026-2036 will vary according to clinical positioning, efficacy, safety, mutation coverage, regulatory status and payer access. Ripretinib is expected to maintain strong adoption in later-line disease because of its broad activity against KIT and PDGFRA mutations. Bezuclastinib may achieve moderate uptake as clinical evidence develops and regulatory decisions clarify its positioning. Earlier-stage therapies such as SAR003 are expected to follow a more gradual trajectory.

The report also evaluates country-specific reimbursement, cost-effectiveness, patient assistance programs, out-of-pocket expenses and coverage under government prescription drug programs. Pricing and analogue assessments examine how treatment cost may influence market access, adherence and long-term commercial performance.
