P201: A Randomized Phase 2b/Phase 3 Study of the TGF-β2 Targeting Antisense Oligonucleotide OT-101 in Combination with FOLFOX Compared with FOLFOX Alone as Second-Line Therapy in Patients with Metastatic Pancreatic Cancer that has Progressed During or Following a First-Line Gemcitabine-Containing Regimen.
OT-101 is a first-in-class anti-TGF-β2 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 COVID-19 virus in our Phase 2 clinical trial- C001.
“Pancreatic cancer is the fourth leading cause of cancer-related mortality with a 5-year survival rate of approximately 10%. Incidence of pancreatic cancer has been steadily increasing despite advances in immunotherapy. Many well known names have succumbed to pancreatic cancer including Apple’s
About OT-101 Pancreatic Cancer Program
Pancreatic cancer is associated with the poorest prognosis of gastrointestinal cancers and is expected to become the second leading cause of cancer-related mortality in the
The P001 trial was an open-label, multicenter dose-escalation study to evaluate the safety and tolerability of OT-101 (TGF-β2-specific Phosphorothioate Antisense Oligodeoxynucleotide) in adult patients with advanced tumors known to overproduce TGF- β2, which are not or no longer amenable to established therapies. Of the 61 patients treated, 37 had advanced treatment failure pancreas cancer, a very difficult-to-treat cancer with an overall survival rate that is measured in months even with the best available chemotherapy regimens. Disease control (complete response (CR)), partial response (PR) or stable disease (SD)) was achieved in 19 of 35 evaluable pancreas cancer patients (54%). Among liver mets only patients, there are exceptional single-agent activity and survival. Patient 1006 was pushed to complete response (CR) and survived as far out as 77 mos. This patient failed multiple lines of therapies: (1) surgery: Whipple's procedure, (2) 1st line: 5-FU/LV, Dose 425 mg/m2, (3) 2nd line: 5-FU/LV, Dose 2600 mg/m2/24hr, (4) 3rd line: Gemcitabine, Dose 1000 mg/m2/week, and (5) went on to OT-101 with liver mets and complete response. Patient 1022 was pushed to stable disease ("SD") with overall survival of 40 months. This patient had also failed multiple lines of therapies: (1) surgery: Whipple's procedure, (2) 1st line: radiation therapy (50 Gy), (3) 2nd line: 5FU, and (4) went on to OT-101 with liver mets and SD.
About OT-101
OT-101, is a first-in-class anti-TGF-β2 RNA therapeutic that exhibited single agent activity in some relapsed/refractory cancer patients in clinical trial settings. HGGs are characterized by a T-cell exhaustion signature and pronounced T-cell hypo responsiveness of their tumor microenvironment (“TME”). TGF-β2 has been implicated as a key contributor to the immunosuppressive landscape of the TME in HGG. OT-101 is designed to abrogate the immunosuppressive actions of TGF- β2. In a completed Phase 2 clinical study, OT-101 exhibited clinically meaningful single-agent activity and induced durable complete and partial responses in recurrent and refractory adult HGG patients, including young adults with Glioblastoma Multiforme or Amyloidosis.
OT-101 has been granted orphan designation by the FDA under the Orphan Drug Act (“ODA”). ODA provides for granting special status to a drug to treat a rare disease or condition upon request of a drug company. Orphan designation qualifies the sponsor of the drug for various development incentives of the ODA, including tax credits for qualified clinical testing. OT-101 also been granted Rare Pediatric Designation for DIPG. The FDA grants rare pediatric disease designation for diseases with serious or life-threatening manifestations that primarily affect people aged from birth to 18 years, and that affect fewer than 200,000 people in the
