Mateon Therapeutics announces oncology articles outlining impact of OT101
Oncotelic, a wholly owned subsidiary of Mateon Therapeutics, announced today the publication of two peer-reviewed expert editorials authored by Fatih Uckun MD PhD, the CMO for Mateon, and Vuong Trieu, PhD, the CEO and President for Mateon, at Oncotelic in the oncology journals Cancer Clinics Journal and Annals of Hematology and Oncology Research. Also published was a peer-reviewed research article in the prestigious oncology journal Cancers. The editorial titled "Monotherapy of High-Grade Gliomas with a TGF-beta2 Targeting RNA Therapeutic" provides an overview regarding the development status, mechanism of action, and clinical potential of Mateon's first-in-class RNA therapeutic OT101 for the treatment of the most aggressive brain tumors in adults. The editorial titled "Convection-enhanced delivery of an anti-TGFbeta RNA therapeutic as a new therapeutic concept for children with diffuse intrinsic pontine glioma ("DIPG")" explains a new concept for the treatment of pediatric DIPG patients with an RNA therapeutic targeting TGFbeta 2 and the scientific rationale and proof of concept data behind it. The research article "Recurrent or Refractory High-Grade Gliomas Treated by Convection-Enhanced Delivery of a TGFbeta2-Targeting RNA Therapeutic: A Post-Hoc Analysis with Long-Term Follow-Up" was published in Cancers as part of the Special Issue Personalized Medicine: Recent Progress in Cancer Therapy. OT101, an RNA therapeutic designed to abrogate the immunosuppressive actions of TGF-beta 2, is Oncotelic's lead anti-brain tumor drug candidate. In a completed Phase 2 clinical study, OT-101 exhibited clinically meaningful single-agent activity and induced durable complete and partial responses in recurrent and refractory adult high-grade glioma patients, including adults with GBM. DIPG, an orphan disease with a low survival rate and no established or effective standard of care. Despite numerous clinical trials of chemotherapeutic agents, immuno-oncology drugs and specific targeted therapies, no significant progress has been made in the treatment of DIPG and the prognosis remains dismal, with a mean OS of 9-12 months from the time of diagnosis, a median survival time of approximately 10 months, and a two-year OS rate of less than 10 percent. Five-year survival is less than 3 percent, and many long-term survivors have evidence of moderate or severe cognitive impairment, likely as a consequence of radiation therapy. Chemotherapy does not have an established role in the management of patients with DIPG. Furthermore, there is no standard treatment for progressive DIPG after the failure of radiation therapy and no salvage regimen has been shown to extend survival. Therefore, there is an urgent need for therapeutic innovations for treatment of DIPG, as reflected by multiple treatment modalities being evaluated in early neuro-oncology clinical trials. Further development of OT-101 may offer renewed hope for salvage therapy not only for adult high-grade glioma patients but also for pediatric DIPG patients. Last month, US Food and Drug Administration granted Rare Pediatric Disease Designation for OT101/Trabedersen for the treatment of diffuse intrinsic pontine glioma as a drug for a "rare pediatric disease," as defined in section 529(a)(3) of the Federal Food, Drug, and Cosmetic Act.
