Oncotelic Therapeutics, Inc. (“Oncotelic” or the “Company”) (OTCQB:OTLC), a leading developer of TGF-β therapeutics for oncology and virology, provided an update on ongoing OT-101/IL-2 combination trial (the “Trial”), which has now successfully completed the safety evaluation of its safety cohort, allowing for further expansion of its clinical program into phase 2 clinical trials and higher doses.
AGOURA HILLS, CA, Nov. 16, 2021 (GLOBE NEWSWIRE) -- Oncotelic Therapeutics, Inc. (“Oncotelic” or the “Company”) (OTCQB:OTLC), a leading developer of TGF-β therapeutics for oncology and virology, provided an update on ongoing OT-101/IL-2 combination trial (the “Trial”), which has now successfully completed the safety evaluation of its safety cohort, allowing for further expansion of its clinical program into phase 2 clinical trials and higher doses.
The Trial, Multi-center, Open label, Phase Ib clinical study to evaluate the safety, tolerance, and efficacy of TASO-001 (“OT-101”), a TGF-β targeting anti-sense oligonucleotide, in combination with recombinant interleukin-2 (Aldesleukin, “IL-2”), in patients with advanced or metastatic solid tumor cancer. ClinicalTrials.gov Identifier: NCT04862767.
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.
In the safety cohort treated during the Trial, the standard dosage of 140mg/m2 of OT-101was well tolerated in combination with IL-2, which has allowed for ongoing dose escalation to 190 mg/m2. The 140 mg/m2 dose was shown to be the optimal dose for OT-101 in the prior trial targeting pancreatic cancer, melanoma, and colorectal cancer (“P001”). In the P001 trial, the maximum tolerated dose was not reached even at 330 mg/m2. Therefore, the Company believes that increasing the dose above 140 mg/m2 should further enhance the clinical activity of OT-101.
“We are excited to see this clear demonstration of safety for the OT-101/IL-2 combination,” noted Dr. Vuong Trieu, CEO of Oncotelic. “Unlike other common treatments, such as chemotherapy, IL-2 has the potential to bring about long-lasting responses and even cures in about one in 10 patients with metastatic kidney cancer and metastatic melanoma. Our analysis to date suggests that the OT-101/IL-2 combination could further improve the cure rate of these cancers. We look forward to updating shareholders as we gain further insights with additional data.”
The Trial is being conducted by Autotelic BIO, a partner of Oncotelic on the OT-101/IL-2 combination, and Clinigen Group, a UK-based global pharmaceutical company.
About OT-101
OT-101 has demonstrated robust efficacy against pancreatic cancer, glioblastoma, and melanoma during phase 2 clinical trials. The demonstration that OT-101 will synergize with IL-2 could further demonstrate its utility as adjunct to other immunotherapies. IL-2, immunotherapy is cancer treatment that stimulates the body’s immune system to fight cancer, such as melanoma. OT-101 has also received orphan drug designation for glioblastoma, melanoma, and pancreatic cancers. Furthermore, the Food and Drug Administration recently granted Rare Pediatric Designation for OT-101 against diffuse intrinsic pontine glioma (DIPG). OT-101 is being evaluated for effectiveness against coronaviruses, including COVID-19, and has been deployed against the COVID-19 epidemic in the Company’s C001 trial.
OT-101 is an antisense against the host TGF-β protein required for viral replication and its overexpression likely to cause the wide range of clinical symptoms associated with COVID-19 including Kawasaki syndrome (Fatih M. Uckun, Vuong Trieu. Targeting Transforming Growth Factor-beta for Treatment of COVID-19-associated Kawasaki Disease in Children. Clin Res Pediatr 2020; 3(1): 1-3) and acute respiratory distress syndrome (ARDS) (Fatih M. Uckun, Larn Hwang, Vuong Trieu. Selectively targeting TGF-β with Trabedersen/OT-101 in treatment of evolving and mild ARDS in COVID-19. Clin. Invest. (Lond.) 2020; 10(2), 167-176. DOI: 10.4172/ Clinical-Investigation.1000166.).
