DGAP-News: Oncotelic's Dr. Anthony Maida to Present at 2nd Annual TGF-ß for Immuno-Oncology Drug Development Summit in January 2022

Oncotelic Therapeutics, Inc. ("Oncotelic" or the "Company") (OTCQB:OTLC), a leading developer of TGF-β therapeutics for oncology and virology, today announced that the Company's Chief Clinical Officer and Board Director, Dr. Anthony Maida, will present at the upcoming 2^nd Annual TGF-β for Immuno-Oncology Drug Development Summit (tgf-beta-summit.com), which will take place virtually from January 25, 2022 to January 27, 2022.

'There is significant worldwide interest in the clinical application of anti-TGF-β inhibitors, in combination with checkpoint inhibitors, as well as other immuno-oncology and chemotherapeutic options. We look forward to sharing the clinical promise of OT-101 in this setting.' noted Dr. Anthony Maida, Chief Clinical Office - Translational Medicine.

TGF-β has been recognized by drug developers, for many years, as holding vast therapeutic potential due to its vital role in cell functioning and signaling. But its complex nature and its ability to be both tumor promoting and tumor suppressing has presented many obstacles for the industry. However, the field appears to be at a tipping point at present, with more candidates moving through clinical evaluation, pointing to an explosion of new data on the way.

'I am excited that we have the opportunity to join other professionals in the field in January to explore novel insights into targeting TGF-β from discovery through clinical testing, and to learn from fellow colleagues such as Genentech, AbbVie, Takeda, and Mestag Therapeutics.' noted Dr. Vuong Trieu, CEO and Chairman of Oncotelic.

OT-101 is a first-in-class anti-TGF-β ribonucleic acid ('RNA') therapeutic that has exhibited single agent activity in relapsed/refractory cancer patients in multiple clinical trials. OT-101 has also demonstrated activity against the SARS-CoV-2 virus, the virus that causes COVID-19, and is currently being evaluated in the Company's C001 clinical trial against hospitalized severe COVID-19 patients. Both tumor cells and SARS-Cov-2 induce TGF-β as part of their immune evasion mechanism.

Consequently, inhibiting TGF-β through therapeutic use of OT-101 carries significant potential to help both cancer and COVID patients in the future.
