Introduction to Avapritinib
Avapritinib, marketed as AYVAKIT or AYVAKYT, is a targeted therapy developed by Blueprint Medicines Corporation. It is designed to treat various cancers and mast cell disorders by inhibiting specific mutations, particularly those involving the KIT and PDGFRA genes.
Clinical Trials Update
Pediatric Solid Tumors Trial
Avapritinib is being investigated in a Phase 1/2 clinical trial for pediatric patients aged 2 to 17 with advanced relapsed/refractory solid tumors, including central nervous system tumors, that harbor PDGFRA and/or KIT mutations. This trial, identified as NCT04773782, aims to determine the safety, pharmacokinetics, and efficacy of avapritinib in this patient population[1].
VOYAGER Trial for GIST
The VOYAGER trial compared avapritinib to regorafenib in patients with third- or fourth-line gastrointestinal stromal tumor (GIST). Although the trial did not meet its primary endpoint of improving progression-free survival (PFS) compared to regorafenib, avapritinib showed a median PFS of 4.2 months and an overall response rate of 17%, with most adverse events being Grade 1 or 2. The safety profile was consistent with previous reports[3].
Indolent Systemic Mastocytosis (ISM) Trial
In a randomized trial, avapritinib demonstrated significant efficacy in reducing symptoms and mast cell burden in patients with indolent systemic mastocytosis (ISM). Patients treated with avapritinib showed a decrease in total symptom score (TSS) and a reduction in serum tryptase levels compared to the placebo group. The trial highlighted the potential of avapritinib in managing ISM, with ongoing studies focusing on long-term safety and efficacy[4].
