ALPHARETTA, GA — May 14, 2026 — (NOTICIAS NEWSWIRE) — Dogwood Therapeutics, Inc. (Nasdaq: DWTX) (“Dogwood” or the “Company”), a company that focuses on developing first-in-class, new non-opioid medicines to treat pain and neuropathy, today announced financial results for the first quarter ended March 31, 2026.

“Dogwood is off to a strong operational start to 2026 driven by significant pipeline progress for both Halneuron®, with Phase 2b data anticipated this fall, and SP16, which received FDA clearance to progress into Phase 1b development this quarter,” said Greg Duncan, Chief Executive Officer of Dogwood Therapeutics. “Furthermore, we executed a global development license for our legacy combination antiviral assets.”

Key Highlights

• The Company currently has enrolled 164 patients in its Halneuron® Phase 2b Chemotherapy Induced Neuropathic Pain (“CINP”) study, with top-line results expected fall of 2026.
• SP16 granted IND approval from the FDA. Study to begin enrolling in mid-2026 for the treatment of chemotherapy-induced pain and peripheral neuropathy (“CIPPN”). It is fully funded by the National Cancer Institute and will be conducted at the University of Virginia.
• In January 2026, the Company completed a financing of up to $26.9 million to progress Halneuron® through Phase 2b development, of which gross proceeds of $12.5 million have been received.
• Cash on hand of $13.2 million provides operational runway into the fourth quarter of 2026.

Dogwood Therapeutics Proprietary Pipeline Includes:

• Halneuron® is in Phase 2b clinical development as a non-opioid, NaV 1.7 inhibitor to treat pain conditions including the neuropathic pain associated with chemotherapy treatment. Halneuron® has been granted fast track designation from the Food and Drug Administration (“FDA”) for the treatment of CINP. Top line results from the ongoing Phase 2b trial are expected in the fall of 2026.
• 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 acts as an LRP1 agonist that 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 Phase 1b CIPPN trial is fully funded by the National Cancer Institute.

First Quarter 2026 Financial Results

Research and development expenses for the first quarter of 2026 were $2.7 million, compared to $2.4 million for the first quarter of 2025.

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 in pain related to chronic CINP. 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 acts as an LRP1 agonist that 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 CIPPN trial is fully funded by the National Cancer Institute.
