Dogwood Therapeutics, Inc. (NASDAQ:DWTX) ("Dogwood" or the "Company"), a biopharmaceutical company developing first-in-class, non-opioid medicines to treat pain and neuropathy, today announced commencement of a new Halneuron® chemotherapy induced neuropathic pain ("CINP") phase 2b extension study. Based on a positive interim assessment demonstrating a Halneuron® 4-week treatment effect versus placebo, Dogwood previously submitted plans to FDA to support commencement of a Halneuron® 12-week follow-on open-label extension study for patients completing the 4-week double-blinded treatment period. Several patients have already been enrolled in the new study that will assess the safety and efficacy of continued Halneuron® treatment for an additional 3 months, using various dosing regimens. Data from the forthcoming extension trial will add to the data package the Company plans to submit to the FDA to support its planned Phase 3 development program, presently projected to start in the first half of 2027.
