Dogwood Enrolls First 200 Patients in Ongoing Halneuron® Phase 2b Chemotherapy Induced Neuropathy Trial; Top-line Data Expected in Fall 2026
Rhea-AI Summary
Dogwood Therapeutics (Nasdaq: DWTX) reported enrollment of the first 200 patients in its ongoing HAL-CINP Phase 2b trial of Halneuron for chemotherapy-induced neuropathic pain. According to the company, the early termination rate among these patients is 4.5%, suggesting Halneuron and placebo have been well tolerated so far.
An independent statistical review committee previously examined unblinded data and concluded Halneuron-treated patients showed separation from placebo in pain improvement over four weeks. HAL-CINP is a randomized trial in approximately 210–240 patients at about 25 U.S. sites, using 8 subcutaneous doses over 14 days and 28 days of follow-up. The primary endpoint is change from baseline to week four in average daily 24-hour recall pain intensity scores, with top-line data expected in fall 2026.
Positive
- First 200 patients enrolled in Phase 2b HAL-CINP trial toward planned 210–240
- Early termination rate of 4.5% among first 200 patients, below typical chronic pain study rates
- Independent review saw Halneuron-treated patients show separation from placebo in pain improvement over four weeks
- Top-line data timeline specified, with four-week study readout expected in fall 2026
Negative
- HAL-CINP efficacy and safety results remain pending until top-line data in fall 2026
- Current data reference is from an interim independent review, not final Phase 2b outcomes

ATLANTA, July 20, 2026 (GLOBE NEWSWIRE) -- Dogwood Therapeutics, Inc. (Nasdaq: DWTX) (the “Company”), a development-stage biotechnology company developing new medicines to treat pain and neuropathy, today announced it has successfully enrolled the first 200 patients in its ongoing HAL-CINP Phase 2b trial. HAL-CINP remains on track for top-line data readout from the four-week study in the fall of 2026.
“In December, an independent statistical review committee reviewed unblinded patient treatment data from the ongoing Phase 2b trial and concluded that Halneuron® treated patients are demonstrating separation from placebo treated patients in terms of pain improvement over the four-week study,” said Greg Duncan, Chief Executive Officer of Dogwood Therapeutics. “The continued low dropout rate of
Halneuron® CINP Phase 2b Trial (“HAL-CINP”) Overview (NCT06848348)
HAL-CINP is a randomized, phase 2b clinical trial evaluating the efficacy and safety of Halneuron® compared with placebo in approximately 210 to 240 patients with moderate to severe neuropathic pain caused by prior platinum and/or taxane-based chemotherapy. Participants receive 8 sub-cutaneous doses of Halneuron® or placebo over a 14-day period and are followed for a total of 28 days for safety and effectiveness. The primary endpoint for this study is the change from baseline to week four in the weekly average of daily 24-hour recall pain intensity scores. The study is being conducted at approximately 25 sites in the U.S. Secondary measures will assess Halneuron’s® treatment effects on sleep, fatigue, neuropathy symptoms and overall patient health.
About Dogwood Therapeutics
Dogwood Therapeutics (Nasdaq: DWTX) is a development-stage biopharmaceutical company focused on developing first-in-class, non-opioid medicines to treat pain and neuropathic disorders. The Dogwood research pipeline includes two first-in-class development candidates, Halneuron® and SP16 IV.
Our lead product candidate, Halneuron®, is in Phase 2b development to treat pain conditions including the neuropathic pain associated with chemotherapy treatment. Halneuron® has been granted fast track designation from the FDA for the treatment of CINP. Halneuron® is a non-opioid, NaV 1.7 analgesic which is a highly specific voltage-gated sodium channel modulator, a mechanism known to be effective for reducing pain transmission. In clinical studies, Halneuron® treatment has demonstrated pain reduction in pain related to general cancer and chronic chemotherapy-induced neuropathic pain. SP16 IV is a low-density lipoprotein receptor related protein-1 agonist (“LRP1”) with potential to treat neuropathy and prevent or repair nerve damage following chemotherapy. SP16’s activity as an LRP1 agonist in turn provides alpha-1-antitrypsin-like activity. Consistent with alpha-1-antitrypsin anti-inflammatory and immunomodulatory actions, SP16 preclinically demonstrated anti-inflammatory (analgesic) action via potential reductions in IL-6, IL-8, IL1B and TNF-alpha levels, as well as potential to repair damaged tissue via increases in pAKT and pERK that regulate fundamental processes like growth, proliferation and survival. The forthcoming SP16 IV Phase 1b CIPN trial is fully funded by the National Cancer Institute.
Dogwood Therapeutics' largest shareholder is a member of CK Life Sciences Int’l., (Holdings) Inc., which is listed on the Hong Kong Stock Exchange (Stock code: 0775).
