OT-101 – an antisense against TGF-β2 – for the treatment of solid tumors with focus on brain cancer 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) developed by Oncotelic 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.

CA4P – a vascular disrupting agent (“VDA”)- in combination with Ipilimumab for the treatment of solid tumors with focus on melanoma in adult and pediatric melanoma. On May 4^th, 2020, FDA granted Rare Pediatric Disease Designation for CA4P/ Fosbretabulin for the treatment of stage IIB–IV melanoma due to genetic mutations that disproportionately affect pediatric patients as a drug for a “rare pediatric disease.”

Oxi4503 – a second generation VDA- for the treatment of liquid tumors with focus on childhood leukemia. US Food and Drug Administration (FDA) granted our request and designate OXi4503 (combretastatin A1-diphosphate; CA1P) for treatment of acute myeloid leukemia (AML) due to genetic mutations that disproportionately affect pediatric patients as a drug for a “rare pediatric disease”, as defined in section 529(a)(3) of the Federal Food, Drug, and Cosmetic Act (FD&C Act) (21 U.S.C. 360ff(a)(3)).

AL-101—intranasal delivery of Apomorphine for the treatment of Parkinson Disease (PD). Over 60,000 new patients 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 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.
