Sunitinib is approved for advanced GIST resistant/refractory to IM; however, disease control rate (DCR) at 12 wk was only ≈ 40%. Thus, novel therapeutic second-line strategies are needed to improve outcomes. Dovitinib inhibits several tyrosine kinases (eg, FGFR, VEGFR, PDGFRß, KIT). DOVIGIST (NCT01478373) is a multicenter, single-arm study to evaluate the efficacy and safety of second-line dovitinib in GIST.


Eligible pts (≥ 18 y) had histologically confirmed GIST; pts had advanced/metastatic GIST refractory/intolerant to IM ≥ 400 mg/day or recurrent GIST after adjuvant IM. All pts had ≥ 1 measurable lesion at baseline. Prior tyrosine kinase inhibitors other than IM were not allowed. Pts received dovitinib 500 mg/day (5 days on/2 days off) until progressive disease (PD), unacceptable toxicity, death, or discontinuation. The primary endpoint was DCR (per RECIST 1.1) at 12 wk. Based on prior trials, DCR ≥45% was deemed clinically meaningful. Key secondary endpoints were progression-free survival (PFS), overall response rate (ORR), and safety.


Of 39 pts who received ≥1 dose of dovitinib, 1 had unconfirmed GIST histology; thus, the efficacy analysis included 38 pts (median age, 60 y). The median time from diagnosis to first dose of dovitinib was 46.3 mo; 81.6% had PD on IM, 13.2% discontinued IM due to intolerance, and 5.2% had intolerance and PD. The most common grade 3/4 dovitinib-related adverse events (AEs) were fatigue (12.8%), diarrhea, vomiting, and hypertriglyceridemia (7.7% each); 21.1% discontinued due to AEs. One pt died of a heart attack (suspected drug related). The median PFS was 20.1 wk (90% CI, 12.3-32.1). DCR at 12 wk was 52.6% (Table).


DOVIGIST met its primary endpoint. The DCR of 52.6% compares favorably with that of other second-line treatments. Dovitinib had promising efficacy and a manageable safety profile, warranting further studies in GIST.
