ATLANTA, Aug. 13, 2025 (GLOBE NEWSWIRE) -- Dogwood Therapeutics, Inc. (NASDAQ:DWTX) (the "Company"), a development-stage biotechnology company developing new medicines to treat pain and fatigue-related disorders, today announced financial results for the second quarter ended June 30, 2025.

"With no FDA approved treatments to manage the neuropathic pain often resulting from chemotherapy treatment, we have the opportunity to potentially enjoy the benefits of being the first and only approved CINP treatment," said Greg Duncan, Chief Executive Officer of Dogwood Therapeutics. "Further, we believe Halneuron's^® clinically significant effects in treating both general cancer pain and chemotherapy induced neuropathic pain highlights the significant potential to expand our Na_V 1.7 research pipeline to other forms of pain, including diabetic peripheral neuropathy, post herpetic neuralgia and acute surgical pain."

"The Na_V 1.7 sodium channel plays a fundamental role in pain transmission, so modulation of this pathway is likely to be applicable to the treatment of both chronic and acute pain states" said Michael Gendreau, MD, PhD, Chief Medical Officer of Dogwood Therapeutics. "A genetic lack of functioning Na_V 1.7 channels leads to a condition known as Congenital Insensitivity to Pain Syndrome, a disorder characterized by the inability to feel pain. Patients who suffer from this condition illustrate the critical role Na_V 1.7 function represents as a pain treatment target."

Key Highlights

To-date, the Company has enrolled 52 patients in its ongoing Halneuron^® Phase 2b CINP program this quarter, with potential to be the first FDA approved therapy for the treatment of CINP.

Dogwood Therapeutics Proprietary Pipeline Includes:

Halneuron^® is in Phase 2b development as a non-opioid, Na_V 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. Interim data from the ongoing Phase 2b CINP study are expected in Q4 2025.
IMC-1 (famciclovir + celecoxib) is ready for Phase 3 development as a combination antiviral treatment for Fibromyalgia ("FM"). IMC-1 has been granted fast track designation by the FDA for the treatment of FM.
IMC-2 (valacyclovir + celecoxib) is in Phase 2a development as a combination antiviral treatment for Long-COVID. Given the importance of Health and Human Services and Medicaid and Medicare funding of both COVID research and reimbursement of treatment, pervasive reductions in government health funding have resulted in us pausing current external research funding and partnership discussions until we have greater clarity on the commitment of U.S. Government resources to COVID illness.

Second Quarter 2025 Financial Results

Research and development expenses for the second quarter of 2025 were $2.5 million, compared to $0.3 million for the second quarter of 2024. The $2.2 million increase quarter over quarter was primarily due to the impact of the business combination with Pharmagesic (the "Combination") including increases in expenses for clinical trials of $1.6 million related to the Halneuron^® CINP Phase 2b study, as well as drug development and manufacturing costs of $0.5 million and salaries and related personnel costs of $0.2 million, offset by a decrease in regulatory costs of $0.1 million.

General and administrative expenses for the second quarter of 2025 were $1.3 million, compared to $0.7 million for the second quarter of 2024. The $0.6 million increase quarter over quarter was primarily due to increases in legal and accounting fees of $0.2 million, salaries and related personnel costs of $0.2 million, expenses associated with being a public company of $0.1 million and other general and administrative costs of $0.1 million.

Net loss attributable to common stockholders for the second quarter of 2025 was $3.8 million, or $1.99 basic and diluted net loss per share, compared to a net loss attributable to common stockholders of $1.0 million, or $1.15 basic and diluted net loss per share, for the second quarter of 2024.

About Dogwood Therapeutics

Dogwood Therapeutics (NASDAQ:DWTX) is a development-stage biopharmaceutical company focused on developing new medicines to treat pain and fatigue-related disorders. The Dogwood research pipeline includes two separate mechanistic platforms with a non-opioid analgesic program and an antiviral program. The proprietary, non-opioid, Na_V 1.7 analgesic program is centered on our lead development candidate, Halneuron^®, 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"). Interim data from the ongoing Halneuron^® Phase 2 CINP study are expected in Q4 of 2025.

Dogwood's antiviral program includes IMC-1 and IMC-2, which are novel, proprietary, fixed-dose combinations of anti-herpes antivirals and the anti-inflammatory agent celecoxib. These combination antiviral approaches are being applied to the treatment of illnesses believed to be related to reactivation of previously dormant herpesviruses, including fibromyalgia ("FM") and Long-COVID ("LC"). IMC-1 is poised to progress into Phase 3 development as a treatment for FM and is the focus of external partnership activities. IMC-2 has been assessed in both active control and double-blind, placebo-controlled clinical trials and, in both cases, demonstrated successful reduction of the fatigue associated with LC. The company has reached an agreement with FDA on using reduction in fatigue as the primary endpoint for future IMC-2 LC research.
