Oncotelic Therapeutics, Inc. (“Oncotelic” or the “Company”) (OTCQB:OTLC), is pleased to announce the grant of patent application no. 15/753,882 entitled “USE OF VDAS TO ENHANCE IMMUNOMODULATING THERAPIES AGAINST TUMORS” by the US Patent Office.
AGOURA HILLS, Calif., May 11, 2022 (GLOBE NEWSWIRE) -- Oncotelic Inc. (“Oncotelic” or the “Company”) (OTCQB:OTLC), is pleased to announce the grant of patent application no. 15/753,882 entitled “USE OF VDAS TO ENHANCE IMMUNOMODULATING THERAPIES AGAINST TUMORS” by the US Patent Office.
The claims of the patent are directed to a pharmaceutical composition for producing an anti-tumor effect in a subject suffering from cancer or a tumor, comprising a Vascular Disrupting Agent (VDA) comprising a combretastatin agent and one or more antibodies selected from the group consisting of: a CTLA-4 antibody, a PD-i antibody, a PD-Li antibody, and a PD-L2 antibody in amounts effective therefore in a pharmaceutical carrier, where in the VDA is combretastatin Al diphosphate (CAl P) or combretastatin A4 phosphate (CA4P) or others.
“With the completion of the Joint Venture with Dragon Overseas Capital Limited for OT-101, we are now in the position to strengthen Mateon’s legacy assets including CA4P and Oxi4503,” said Dr. Vuong Trieu, CEO and Chairman. “Given our team experience in VDA space as well as Abraxane and Cynviloq, we feel that we can successfully redeploy CA4P and Oxi4503 for the treatment of difficult to treat cancers either alone or in combination with Pembrolizumab/Keytruda.”
About Oncotelic
Oncotelic (f/k/a Mateon Therapeutics, Inc.), was formed in the State of New York in 1988 as OXiGENE, Inc., was reincorporated in the State of Delaware in 1992, and changed its name to Mateon Therapeutics, Inc. in 2016, and Oncotelic Therapeutics, Inc. in November 2020. Oncotelic is seeking to leverage its deep expertise in oncology drug development to improve treatment outcomes and survival of cancer patients with a special emphasis on rare pediatric cancers. Oncotelic has rare pediatric designation for DIPG (OT-101), melanoma (CA4P), and AML (OXi 4503). Oncotelic also acquired PointR Data Inc. in November 2019.
Additionally, Oncotelic acquired AL-101, during the 4th quarter of 2021, for the intranasal delivery of apomorphine. We intend to develop AL-101 for the treatment of Parkinson Disease (“PD”). Over 60,000 new patients are being diagnosed with PD in the United States and currently there are over 1 million patients in the US and expected to increase to over 1.2 million by 2030. In addition, approximately 10 million suffer from this disease globally. https://www.parkinson.org/Understanding-Parkinsons/Statistics. AL-101 is also being developed for Erectile Dysfunction (“ED”). ED is the most prevalent male sexual disorder globally. The percentages of men affected by ED are as follows: 14.3-70% of men aged ≥60 years, 6.7-48% of men aged ≥70 years, and 38% of men aged ≥80 years (Geerkens MJM et al. (2019). Eur Urol Focus. pii: S2405-4569(19)30079-3). However, with the increasing administration of PDE5 inhibitors in clinical practice, it was found that approximately 30-35% of ED patients are treatment failures (McMahon CN et al. (2006). BMJ, 332: 589-92). AL-101 is designed to target treatment failure ED patients who do not respond to PDE5 inhibitors. Through similar mechanism of action, AL-101 is being developed for Female Sexual Dysfunction (“FSD”). Female sexual dysfunction is a prevalent problem, afflicting approximately 40% of women and there are few treatment options. FSD is more typical as women age and is a progressive and widespread condition. (Allahdadi, KJ et al. (2009) Cardiovascular & hematological agents in medicinal chemistry, 7(4), 260–269). There is no available drug for the treatment of FSD. In June 2019, the U.S. Food and Drug Administration approved Vyleesi (bremelanotide) to treat acquired, generalized hypoactive sexual desire disorder (“HSDD”) in premenopausal women. This is the only available drug treatment. Vyleesi has essentially replaced the only other drug for HSDD – however, it has a long list of drug-drug interactions, including commonly used antidepressants, such as fluoxetine and sertraline. In addition, it has a black box warning regarding its use with alcohol, a combination that has been associated with hypotension and syncopal episodes. Therefore, there is an urgent need for effective therapy against FSD and HSDD.
About CA4P
CA4P causes rapid and widespread tumor cell necrosis. CA4P increases the immunogenic effect of checkpoint inhibitors when used alone as monotherapy. Tumor-fighting white blood cell counts, T-cells and cytotoxic T-cells compared to immuno-oncology agents alone. Tumor necrosis with the combination of CA4P and immuno-oncology agents is nearly double the necrosis with only immuno-oncology agents (63.9% compared to 32.8%, control = 25.8%). The overall data from all these studies provides evidence that CA4P may enhance the activity of immuno-oncology agents for the treatment of cancer, including anti-CTLA4 antibodies. The FDA has granted Rare Pediatric Disease Designation for CA4P/ Fosbretabulin tromethamine for the treatment of stage IIB–IV melanoma due to genetic mutations that disproportionately affect pediatric patients as a drug.
