ORYZON to present trial in progress Phase Ib FRIDA study at the upcoming 2023 ASCO annual meeting

Oryzon Genomics, S.A., a clinical-stage biopharmaceutical company leveraging epigenetics to develop therapies in diseases with strong unmet medical need, today announced the presentation of the trial in progress (TIP) FRIDA poster entitled Iadademstat in combination with gilteritinib for patients with mutated FLT3 relapsed/refractory acute myeloid leukemia at the upcoming American Society of Clinical Oncology (ASCO) 2023 Annual Meeting, to be held in-person from June 2-6, 2023 at the McCormick Place in Chicago, Illinois.

Dr. Amir Fathi, Director of the Leukemia Program at Massachusetts General Hospital, is the Principal Investigator of the study and first author of the poster. He will be recording a brief video summarizing the poster information and study status.

Dr. Douglas V. Faller, Oryzon’s Global Chief Medical Officer, will attend the poster presentation, which will take place during the Poster Discussion Session on Monday June 5 from 8:00 AM-11:00 AM within the Hematologic Malignancies—Leukemia, Myelodysplastic Syndromes, and Allotransplant Session.

FRIDA (NCT05546580) is an open-label, multicenter study of iadademstat plus gilteritinib for the treatment of patients with relapsed or refractory AML (R/R AML) with FLT3·mutations. The trial’s primary objectives are to evaluate the safety and tolerability of iadademstat in combination with gilteritinib in patients with FLT3mut+ R/R AML and to establish the Recommended Phase 2 Dose (RP2D) for this combination. Secondary objectives include evaluation of the treatment efficacy, measured as the rate of complete remission and complete remission with partial hematological recovery (CR/CRh), the duration of responses (DoR) and the assessment of measurable residual disease (MRD). FRIDA will be conducted in 10-15 sites in the US. The study will enroll up to approximately 45 patients and if successful, the Company and FDA have agreed to hold a meeting to discuss the best plan to further develop this combination in this much in need AML population.

Presentation materials will be available both on the ASCO website and on our website under the Events section following the session.

About Iadademstat

Iadademstat (ORY-1001) is a small oral molecule, which acts as a highly selective inhibitor of the epigenetic enzyme LSD1 and has a powerful differentiating effect in hematologic cancers (see Maes et al., Cancer Cell 2018 Mar 12; 33 (3): 495-511.e12.doi: 10.1016 / j.ccell.2018.02.002.). A FiM Phase I/IIa clinical trial with iadademstat in R/R AML patients demonstrated the safety and good tolerability of the drug and preliminary signs of antileukemic activity, including a CRi (see Salamero et al, J Clin Oncol, 2020, 38(36): 4260-4273. doi: 10.1200/JCO.19.03250). In a recently completed Phase IIa trial in elder 1L-AML patients (ALICE trial), iadademstat has shown encouraging safety and efficacy data in combination with azacitidine (see Salamero et al., ASH 2022 oral presentation). Iadademstatis currently being evaluated in combination with gilteritinib in the Phase Ib FRIDA trialin patients with relapsed/refractory AML with FLT3 mutations. Beyond hematological cancers, the inhibition of LSD1 has been proposed as a valid therapeutic approach in some solid tumors such as small cell lung cancer (SCLC), neuroendocrine tumors (NET), medulloblastoma and others. In a Phase IIa trial in combination with platinum/etoposide in second line ED-SCLC patients (CLEPSIDRA trial), preliminary activity and safety results have been reported (see Navarro et al., ESMO 2018 poster). Iadademstat is being evaluated in a collaborative Phase II basket study with the Fox Chase Cancer Center in combination with paclitaxel in R/R neuroendocrine carcinomas, and the company is preparing a new trial in combination in SCLC. Oryzon has entered into a Cooperative Research and Development Agreement (CRADA) with the U.S. National Cancer Institute (NCI) to collaborate on potential further clinical development of iadademstat in different types of solid and hematological cancers. In total iadademstat has been dosed so far to more than 100 cancer patients in four clinical trials. Iadademstat has orphan drug designation for SCLC in the US and for AML in the US and EU.
