GIST

Compared with sunitinib, second-line treatment with ripretinib did not improve progression-free survival in patients with gastrointestinal stromal tumor.

Pimitespib, a heat shock protein 90 inhibitor doubled the progression-free survival and prolonged the overall survival compared with placebo in patients with advanced gastrointestinal stromal tumor that is refractory to imatinib, sunitinib, and regorafenib, according to results from the phase 3 CHAPTER-GIST-301 trial.

Patients with advanced gastrointestinal stromal tumor after receiving fourth-line therapy had extended progression-free survival when given an intra-patient dose escalation of ripretinib to 150 mg twice a day following progression.

A retrospective analysis showed there were more durable survival outcomes with avapritinib versus other tyrosine kinase inhibitors in adult patients with gastrointestinal stromal tumors and a platelet-derived growth factor receptor A D842V mutation

Adjuvant imatinib has demonstrated significant improvement in relapse-free survival over a 2-year period and a mild trend toward long-term improvement in failure-free survival as treatment of patients with high-risk gastrointestinal stromal tumors, according to 9.1-year follow-up results from a randomized phase 3 study.

In patients with gastrointestinal stromal tumors who have received 3 or more prior therapies, there remain unmet needs to overcome resistance to the standard-of-care, imatinib, a tyrosine kinase inhibitor, and prolong the 6.3-month+ progression-free survival achieved with the FDA-approved TKI ripretinib.
