News Release Details

WESTPORT, Conn., Aug. 30, 2023 (GLOBE NEWSWIRE) -- Portage Biotech Inc. (NASDAQ: PRTG), a clinical-stage immuno-oncology company advancing novel multi-targeted therapies for use as monotherapy and in combination, today reported financial results for the fiscal quarter ended June 30, 2023.

“In recent weeks we have continued to build on the favorable interim data and early evidence of single agent activity from the Phase 1/2 trial of our lead program, PORT-2, presented at the 2023 annual meeting of the American Society for Clinical Oncology (ASCO) in June, and our near-term focus is defining the recommended Phase 2 dose,” said Dr. Ian Walters, Chief Executive Officer, and Chairman of Portage Biotech. “We have transferred sponsorship of the clinical trial from the academic sponsor to Portage and amended the protocol to include a higher dose level. As a result, we are significantly expanding our clinical footprint to 17 planned sites with the goal of speeding up patient accrual by adding 15 additional sites, in the US, UK, and Spain. We expect final data from the Phase 1 portion of the trial in the first calendar quarter of 2024.”

“In July, we announced the dosing of the first patient in our adaptive Phase 1a/1b trial, ADPORT-601 evaluating PORT-6, our adenosine 2A receptor (A2A) antagonist candidate, and have completed enrollment in the low dose cohort,” continued Dr. Walters. “As with our PORT-2 program, we are keenly focused on activating quality clinical sites and establishing a broad footprint to support patient accrual. Several sites including MD Anderson Cancer Center, UCSF Comprehensive Cancer Center, The USC Norris Comprehensive Cancer Center, Thomas Jefferson University, Virginia Cancer Specialists, Norton Cancer Institute, Washington University School of Medicine, and Sarah Canon Research Institute are currently participating. We are also in the process of amending the trial to include PORT-7, our adenosine 2B receptor (A2B) antagonist candidate, dose escalation and combinations with PORT-6 arms. We are confident in our clinical programs and development approach and are excited to see the data generated by all three assets.”

Company Highlights

• Announced dosing of the first patient in the Phase 1a trial, ADPORT-601 (NCT04969315). The trial is evaluating PORT-6 in patients with solid tumors including prostate cancer, renal and non-small cell lung cancer. The ADPORT-601 trial includes plans to also evaluate PORT-7and is designed to adapt over time, including safety and efficacy cohorts for both candidates as monotherapy and in combination with checkpoint inhibitors as well as other immune activating agents from Portage’s pipeline.
  
  
• Presented favorable interim data for lead iNKT engager PORT-2 from the Phase 1/2 trial for the treatment of patients with advanced melanoma and metastatic non-small cell lung cancer at ASCO. The presented data showed early evidence of monotherapy activity and meaningful reduction of several target lesions with minimal toxicity.
  

Financial Results from Quarter Ended June 30, 2023

The Company incurred a net loss of approximately $5.9 million and total comprehensive loss of approximately $4.2 million during the three months ended June 30, 2023 (the “Fiscal 2024 Quarter”), which include approximately $1.7 million of non-cash expenses, net, compared to a net loss and total comprehensive loss of approximately $1.6 million during the three months ended June 30, 2022 (the “Fiscal 2023 Quarter”), an increase in net loss of $4.3 million and an increase in total comprehensive loss of $2.6 million from the Fiscal 2023 Quarter.

Operating expenses for the Fiscal 2024 Quarter, which include research and development (“R&D”) costs and general and administrative (“G&A”) expenses, were $5.0 million compared to $4.1 million in the Fiscal 2023 Quarter, an increase of $0.9 million, which is discussed more fully below.

R&D costs increased by approximately $1.7 million to approximately $3.6 million, or approximately 89%, for the Fiscal 2024 Quarter from approximately $1.9 million in the Fiscal 2023 Quarter. The increase was primarily attributable to an overall increase in clinical trial costs of $0.8 million, part of $1.4 million of start-up and manufacturing costs associated with the adenosine assets (PORT-6 and PORT-7) acquired in the Tarus acquisition, and the clinical trial costs and other R&D costs associated with the iNKT clinical trial for PORT-2 totaling $1.7 million. Additionally, the Company incurred a contractual milestone obligation of $0.5 million upon the dosing of the first PORT-6 patient. These increases reflect the increase in clinical activity and manufacturing costs related to accelerating the development of the Company’s adenosine and iNKT development programs.

G&A expenses decreased by approximately $0.8 million to approximately $1.4 million, or approximately 36%, from approximately $2.2 million in the Fiscal 2023 Quarter. Professional fees decreased by $0.4 million, primarily attributable to legal fees associated with the Tarus acquisition in the Fiscal 2023 Quarter.

As of June 30, 2023, the Company had cash and cash equivalents of approximately $7.7 million, and total current liabilities of approximately $2.6 million.
