"The Company continues to execute at a high level, including recruitment of 100 patients in our ongoing Halneuron^® Phase 2b trial and the addition of a, synergistic and complementary pipeline asset, SP16, a novel, first-in-class development candidate for cancer related pain," said Greg Duncan, Chief Executive Officer of Dogwood Therapeutics.

Third Quarter 2025 Financial Results

Research and development expenses for the third quarter of 2025 were $14.5 million, compared to $0.5 million for the third quarter of 2024. The $14.0 million increase quarter over quarter was primarily related to acquired in-process research and development expenses of $12.0 million associated with the licensing agreement of SP16, the impact of the business combination with Pharmagesic (Holdings) Inc., including increases in expenses for clinical trials of $1.9 million related to the Halneuron^® CINP Phase 2b study, as well as drug development and manufacturing costs of $0.3 million and salaries and related personnel costs of $0.1 million, offset by a decrease in research and preclinical costs of $0.3 million.

General and administrative expenses for the third quarter of 2025 were $1.3 million, compared to $1.8 million for the third quarter of 2024. The $0.5 million decrease quarter over quarter was primarily due to a decrease in legal and accounting fees of $0.5 million and a decrease in expenses associated with being a public company of $0.2 million, offset by an increase in salaries and related personnel costs of $0.2 million.

Net loss attributable to common stockholders for the third quarter of 2025 was $15.7 million, or $8.20 basic and diluted net loss per share, compared to a net loss attributable to common stockholders of $2.3 million, or $2.05 basic and diluted net loss per share, for the third quarter of 2024.

Cash on hand of $10.1 million provides operational runway through the first quarter of 2026.

About Dogwood Therapeutics

Dogwood Therapeutics (NASDAQ:DWTX) is a development-stage biopharmaceutical company focused on developing new 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 Food and Drug Administration ("FDA") for the treatment of CINP. Halneuron^® is a non-opioid, Na_V 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 chemotherapy-induced neuropathic pain ("CINP").

SP16 IV is a low-density lipoprotein receptor related protein-1 (LRP1) agonist 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 CINP trial will commence following consultation with FDA and is fully funded by the National Cancer Institute.
