(NASDAQ: DWTX) (\u201cDWTX\u201d, \u201cDogwood\u201d or \u201cthe Company\u201d), a company that focuses on developing new non-opioid medicines to treat pain and neuropathy, today announced FDA acceptance of an Investigational New Drug (\u201cIND\u201d) application for its development candidate SP16, administered intravenously (\u201cIV\u201d), for the treatment of chemotherapy-induced pain and peripheral neuropathy (\u201cCIPPN\u201d).<\/p>\n<p align=\"justify\">SP16 is administered via IV infusion with two hypothesized actions: anti-inflammatory actions via reduction of IL-6, IL-8, IL-1\u03b2 and TNF-alpha, and tissue repair via increases in pAKT and pERK that regulate and promote fundamental processes like growth, proliferation, and survival. The Company and its partner Serpin Pharma anticipate patient enrollment in the SP16 Phase 1b trial to begin in the middle of 2026. Serpin Pharma has been awarded a $2.5 million grant from the National Cancer Institute (\u201cNCI\u201d), which will fully fund the forthcoming SP16 Phase 1b CIPPN clinical trial.<\/p>\n<p align=\"justify\">\u201cFDA acceptance of our SP16 IND filing represents an important step in expanding our pipeline as we advance a second development candidate into the clinic to treat chemotherapy-induced neuropathy and pain,\u201d said\u00a0Greg Duncan, Chairman and Chief Executive Officer\u00a0of Dogwood Therapeutics. \u201cSP16 compliments our lead candidate, Halneuron<sup>\u00ae<\/sup>,\u00a0by not only targeting neuropathic pain but also addressing additional debilitating symptoms of neurotoxic chemotherapy, including numbness, tingling and impaired motor function.\u201d<\/p>\n<p align=\"justify\">Incidence of CIPPN is high, affecting\u00a0approximately\u00a030-40% of patients\u00a0six months after receiving neurotoxic chemotherapy, and can persist long-term in many patients.\u00a0\u00a0 Key risk factors for the development of these symptoms include use of platinum or taxane containing drugs, higher chemotherapeutic doses, and underlying diabetes. Common symptoms associated with CIPPN are numbness, tingling, and pain, symptoms that directly impact quality of life in these cancer survivors.\u00a0<\/p>\n<p align=\"justify\">In September 2025, Dogwood secured the SP16 royalty-free, global license to develop and commercialize Serpin Pharma\u2019s IV formulation of SP16 to manage CIPPN. Serpin Pharma is the holder of the IND and the regulatory sponsor of the program.<\/p>\n<p align=\"justify\">\n        <strong>About Dogwood Therapeutics:<\/strong>\n      <\/p>\n<p align=\"justify\">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<sup>\u00ae<\/sup>\u00a0and SP16 IV.<\/p>\n<p align=\"justify\">Our lead product candidate, Halneuron<sup>\u00ae<\/sup>,\u00a0is in Phase 2b development to treat pain conditions including the neuropathic pain associated with chemotherapy treatment. Halneuron<sup>\u00ae<\/sup>\u00a0has been granted fast track designation from the FDA for the treatment of CINP. Halneuron<sup>\u00ae<\/sup>\u00a0is a non-opioid, Na<sub>V<\/sub>\u00a01.7 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<sup>\u00ae<\/sup>\u00a0treatment has demonstrated pain reduction in pain related to general cancer and in pain related to chronic chemotherapy-induced neuropathic pain (\u201cCINP\u201d). 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.<\/p>\n<p align=\"justify\">Dogwood Therapeutic\u2019s largest shareholder is a member of CK Life Sciences Int\u2019l., (Holdings) Inc., which is listed on the Hong Kong Stock Exchange (Stock code: 0775).<\/p>\n<p align=\"justify\">For more information, please visit\u00a0<a href=\"https:\/\/www.globenewswire.com\/Tracker?data=GNLeva5JofOPzgKTf9CAJM9wtFSjQ_XfuCfaJLEfzuO8c-C7uYu78T9dsvkBoLpPwVuPiUebJEO7HtmfbE3xfZw7YQrtIkMb8696dMut7IO60Cy-4lMiQSMYHSBPabmHCh7AVrGWBaEvwyXwHdXX3qBuHLxcj9ZMEnI05VZHdO62g0Rzw-qFLrjrc7XTvts2OJ8rbKHVom2qTCroFdNEEeES9v0nIAql6HglGvq22dV-saSKqrUKyrh_rsJukKaMIdYH4ejlcMBKRvzi1eKl0M4SaPsRN5PKbwN7A-0OJcQ4cbW31LFdmZ0LAJlqeW66IZGtWj1fUEIs3Vy_WXS0muRbUsDtnyE57qJhG0ybMUepQlQgpMJMPc1LdifLRABe8cuzTH9lU_WDZ53Ge5DNjVozuo_1HWYlKIRuHQRr6_Q=\" rel=\"nofollow\" target=\"_blank\">www.dwtx.com<\/a>.<\/p>\n<p align=\"justify\">\n        <strong>Forward-Looking Statements:<\/strong>\n      <\/p>\n<p align=\"justify\">Statements in this press release contain \u201cforward-looking statements,\u201d within the meaning of the U.S. Private Securities Litigation Reform Act of 1995, that are subject to substantial risks and uncertainties.
