Investigational drug for GIST is on the fast track

The Food and Drug Administration has decided to grant regorafenib fast-track status. The drug is in phase 3 testing for the treatment of gastrointestinal stromal tumors (GIST), a rare type of sarcoma. Fast tracking typically helps move drugs that fill unmet needs and treat serious conditions, such as GIST, as fast as possible through the pipeline. The phase 3 clinical trial, which started in January, will be examining 170 patients with inoperable GIST who will receive either regorafenib or placebo. (If patients who are on placebo have disease progression, they may be allowed to receive regorafenib.) Data from a phase 2 trial of regorafenib will be presented next month at the annual meeting of the American Society of Clinical Oncology. Other drugs approved for GIST include Gleevec (imatinib) and Sutent (sunitinib). Patients in the phase 3 trial will have progressed on either drug. Unlike Gleevec, which targets one specific mutation called bcr-abl, regorafenib is a multikinase inhibitor, acting against several signals, including VEGF, RAF and KIT.
