Pipeline

platON™ is Onxeo’s proprietary chemistry platform of oligonucleotides acting as decoy agonists, which generates new innovative compounds that broaden the Company’s product pipeline.

AsiDNA™, the first compound sourced from platON™, is a first-in-class, highly differentiated DNA Damage Response (DDR) inhibitor based on a decoy mechanism with an agonist effect, acting upstream of multiple DDR pathways. AsiDNA™ has the ability to abrogate tumor resistance to PARP inhibitors regardless of the genetic mutation status. AsiDNA™ has also shown a strong synergy with other tumor DNA-damaging agents such as chemotherapy, radiotherapy and PARP inhibitors. Thanks to a good safety profile, AsiDNA™ is particularly amenable to combination treatment, a standard of care in aggressive or resistant cancers. AsiDNA™ is currently evaluated in a phase 1b study in combination with chemotherapy and its clinical evaluation in combination with PARP inhibitors is expected to start shortly.

OX401 is the second drug candidate from platON™, optimized to be a next-generation PARP inhibitor acting on both the DNA Damage Response and the activation of immune response, without inducing resistance.

Onxeo’s portfolio also includes belinostat, an HDAC inhibitor (epigenetics). Belinostat is already conditionally FDA-approved in the US as a 2nd line treatment for patients with peripheral T cell lymphoma and marketed in the US under the name Beleodaq® (belinostat IV form).
