OT-101 – an antisense against TGF-β2 – for the treatment of solid tumors in adult and DIPG in children. RPD for pediatric DIPG granted by US FDA. OT-101, also referred to Trabedersen, is a novel antisense oligodeoxynucleotide (ODN) for the treatment of patients with pancreatic carcinoma, malignant melanoma, colorectal carcinoma, high-grade glioma (HGG), and other transforming growth factor beta 2 (TGF-β2) overexpressing malignancies (e.g., prostate carcinoma, renal cell carcinoma, etc.).

Trabedersen is a synthetic 18-mer phosphorothioate oligodeoxynucleotide (S-ODN) complementary to the messenger ribonucleic acid (mRNA) of the human TGF-β2 gene. Cancers overexpress TGF-β, which suppresses host innate immune response to the cancers. Treatment with OT-101 lifts the TGF-β cloaking effect and allows innate or therapeutic immunity to attack and eliminate the cancers.

We have completed phase 2 for pancreatic cancer and melanoma, and phase 2 in glioblastoma with robust efficacy and safety.

OT-101 – an antisense against TGF-β2 –for the treatment of various viruses, including the SARS and the current COVID-19, on its own and in conjunction with other compounds.
