Clearance enables Phase 2 evaluation of NEO212, the Company's oral perillyl alcohol-temozolomide conjugate, in the United Arab Emirates

Follows completion of Phase 1 dose escalation and selection of 610 mg as the recommended Phase 2 dose

Adds an international clinical pathway alongside continuing U.S. FDA discussions on a potential registrational pathway for NEO212

CALABASAS, Calif., June 16, 2026 (GLOBE NEWSWIRE) -- NeOnc Technologies Holdings, Inc. (NASDAQ:NTHI) ("NeOnc" or the "Company"), a clinical-stage biopharmaceutical company developing novel therapies for central nervous system (CNS) cancers, today announced that the Department of Health – Abu Dhabi (DOH) has granted Investigational New Drug (IND) status for NEO212, the Company's orally administered perillyl alcohol-temozolomide carbamate conjugate being developed for patients with aggressive brain tumors. The authorization marks the first international regulatory clearance for NEO212 following completion of Phase 1 clinical evaluation and represents a significant step toward expanding the program into multiple global markets.

NEO212 recently completed the Phase 1 dose-escalation portion of its Phase 1/2 study, which established 610 mg as the recommended Phase 2 dose. In that study, the Company reported encouraging early signs of clinical activity, including potential durable disease stabilization, in heavily pretreated patients with recurrent glioblastoma (GBM) and brain metastases. NeOnc expects this authorization to support the advancement of NEO212 into Phase 2 clinical development while continuing discussions with the U.S. Food and Drug Administration regarding the design of a potential registrational pathway. The Company believes parallel regulatory and clinical activities across multiple jurisdictions may accelerate the overall development strategy for NEO212.

Under the terms of the DOH authorization, NeOnc must satisfy a number of conditions before patient enrollment in the UAE, including separate approval from the DOH Institutional Review Board (IRB) and amendments to the study protocol, investigator's brochure, and product labeling. The DOH clearance applies to the conduct of clinical research and does not constitute marketing authorization.

The Company has also submitted applications to the Department of Health – Abu Dhabi for its NEO100 clinical programs, including NEO100-01, NEO100-02, and NEO100-03, and is currently awaiting regulatory decisions. If approved, these programs would further expand NeOnc's clinical development footprint in the UAE and support the Company's strategy of advancing multiple brain cancer and neurological therapeutic programs in parallel across key international markets.

Glioblastoma remains one of the deadliest forms of cancer, with limited treatment options and poor long-term survival outcomes. NEO212 is designed to combine the chemotherapeutic temozolomide with perillyl alcohol in a single orally administered conjugate intended to improve delivery across the blood-brain barrier. The Company expects to work with healthcare institutions, investigators, and regulatory authorities in the UAE as clinical development activities advance.
