• OT-101 is Oncotelic’s RNA Therapeutic Against TGF-β
• OT-101 has completed over six clinical trials against solid tumors with good efficacy
• OT-101 is currently undergoing a phase 1b trial in combination with IL-2
• Multiple trials combining OT-101 with pembrolizumab are in development
• OT-101 has also completed a phase 2 trial against COVID with good efficacy

Oncotelic Therapeutics, Inc. (“Oncotelic” or the “Company”) (OTCQB:OTLC), a leading developer of TGF-β therapeutics for oncology and virology, today announced that Dr. Vuong Trieu, Oncotelic Chairman and CEO, will be presenting the Company immunotherapy pipeline at BiotechGate Digital Partnering Feb 7 - 11, 2022.

Biotechgate Digital Partnering is a premier platform for business licensing and collaboration focusing on companies developing drugs, diagnostics and medical devices. It is an ideal platform to unveil the fully integrated platform of immunotherapies at Oncotelic.

The OT-101 oncology program (“OT-101-ONC”) is designed to assess the impact of OT-101 across multiple oncology indications, where local tumoral secretion of TGF-β suppressed the clinical activity of checkpoint inhibitors, CAR-T, and vaccine. The OT-101-ONC program has been moving forward steadily through strategic alliances planned with top pharmaceutical companies. Of note is the biomarker program spanning mesothelioma, glioblastoma, lung and colorectal cancers, where AI driven transcriptome analyses will be used to derive the predictive biomarker for TGF-β therapeutics such as OT-101.

In June 2020, the Food and Drug Administration (the “FDA”) granted accelerated approval to pembrolizumab for the treatment of adult and pediatric patients with unresectable or metastatic tumor mutational burden-high (TMB-H) [≥10 mutations/megabase (mut/Mb)] solid tumors, as determined by a FDA-approved test, that have progressed following prior treatment and who have no satisfactory alternative treatment options. We intend to utilize the same approval route for OT-101/ pembrolizumab combination.

"Our phase 2 trials are designed to for the eventual approval of OT-101 against any solid tumors, with high-TGF signature, as determined by our companion diagnostic assay" said Dr. Vuong Trieu, CEO and Chairman of Oncotelic. “We believe this will be transformative and we are appreciative of the support we have received from leading investigators and partners.”
