Oryzon Secures Key AML Combination Patent, Bolsters Iadademstat IP

  • Oryzon Genomics has been granted U.S. Patent US12,564,559 B2 covering combinations of its LSD1 inhibitor, iadademstat, with venetoclax.
  • The patent, expiring in January 2039 (including patent term adjustment), protects methods of treating acute myeloid leukemia (AML) using these combinations.
  • Preliminary data from a Phase Ib clinical trial (ALICE-2) showed a 100% overall response rate (ORR) and 90% complete remission rate with iadademstat, venetoclax, and azacitidine.
  • Updated data from the ALICE-2 trial, involving approximately 15-16 patients, are expected to be presented at the EHA Annual Congress in June 2026.

The patent grant strengthens Oryzon's IP position for iadademstat, a key asset in the competitive oncology market. The combination with venetoclax, a standard of care for AML, represents a significant opportunity, but the 100% ORR data, while promising, requires further validation. Success hinges on demonstrating sustained efficacy and navigating the complexities of regulatory approval and market access in a crowded therapeutic area.

Clinical Efficacy
The June EHA presentation will be critical to validating the initial 100% ORR data and assessing the long-term durability of responses in the ALICE-2 trial, which will inform the drug's commercial viability.
Regulatory Pathway
The potential for further patent term extensions related to regulatory review could significantly impact Oryzon’s market exclusivity and profitability, especially given the competitive landscape in AML treatment.
Competitive Dynamics
How the emergence of other LSD1 inhibitors or novel AML therapies will affect iadademstat’s adoption and Oryzon’s ability to maintain a differentiated position in the market remains to be seen.
