OCT-3598 / Oscotec, Kanaph Therap - LARVOL DELTA

Oscotec submits clinical trial application for next-generation anti-cancer drug in Korea (Chosun Biz) - "Oscotec announced on the 21st that it has submitted a clinical trial plan (IND) for its next-generation anti-cancer drug candidate 'OCT-598' to the Ministry of Food and Drug Safety to overcome cancer drug resistance. Last month, it received IND approval for phase 1 clinical trials from the U.S. Food and Drug Administration (FDA). This phase 1 trial will evaluate the safety, tolerability, and pharmacokinetic properties of OCT-598 in up to 51 patients with advanced solid tumors in the United States and Korea. OCT-598 is a dual-action anti-cancer drug that simultaneously inhibits the receptors EP2 and EP4 of prostaglandin E2 (PGE2)."

Oscotec, application for approval of clinical trial plan [Google translation] (HIT News) - "The company submitted a phase 1 clinical trial plan (IND) for OCT-598, a candidate substance for the treatment of advanced solid tumors, to the U.S. Food and Drug Administration (FDA)."

Inhibition of PGE2 signaling by an EP2/4 dual antagonist OCT-598 prevents acquisition of therapy-resistance and tumor relapse (AACR 2025) - "In vivo, OCT-598 abrogated tumor relapse after irradiation in CT26 mouse syngeneic tumor model, leading to complete remissions. Based on these observations, a clinical trial is set to be initiated to test the "anti-resistance" activity of OCT-598 as an adjuvant to the standard-of-care treatment in patients with advanced solid tumors."

OCT-598, a novel EP2/EP4 dual antagonist, promotes anti-tumor immune responses in syngeneic mouse tumor models in combination with standard-of-care chemo- and immunotherapies (AACR 2023) - "Furthermore, the addition of OCT-598 to the lung cancer standard-of-care regimen (anti-PD-1 plus chemotherapy) in TC-1 mouse lung adenocarcinoma model gave rise to complete tumor regression. In conclusion, dual blockade of EP2 and EP4 by OCT-598 is shown to be a compelling strategy to reinforce antitumor effects by thwarting PGE2-mediated therapy resistance and immune evasion.Findings from this study provide a rationale for clinical development of OCT-598 as a therapeutic option for human malignant cancers."
