WESTPORT, Conn., Nov. 29, 2022 (GLOBE NEWSWIRE) -- Portage Biotech Inc., (NASDAQ: PRTG) (“Portage” or the “Company”), a clinical-stage immuno-oncology company developing therapies to improve patient lives and increase survival by avoiding and overcoming cancer treatment resistance, today announced financial results for the fiscal quarter ended September 30, 2022.

“During the quarter and in recent weeks we have continued to demonstrate progress of our invariant natural killer T cell (iNKT) agonist, PORT-2, as well as our broader portfolio of immuno-oncology assets,” said Dr. Ian Waters, Chief Executive Officer and Chairman of Portage Biotech. “Updates on PORT-2 include the data presented from our IMPORT-201 Phase 1/2 clinical trial of PORT-2 (IMM60) at the SITC annual conference, which continue to show PORT-2 has a favorable safety and tolerability profile as a monotherapy at all doses tested to date. We also announced a new clinical collaboration agreement with Merck to evaluate PORT-2 in combination with KEYTRUDA^® (pembrolizumab), and look forward to exploring how this therapeutic combination may further enhance long-term clinical benefit for a wide range of patients with cancer. We are also preparing to launch our company-sponsored ADPORT-601 adenosine trial for PORT-6 and PORT-7 in the U.S. We look forward to building on this progress and advancing our broader strategy of de-risked clinical development, and are well positioned to deliver on multiple catalysts in the coming months.”

Pipeline & Clinical Program Highlights from the Quarter Ended September 30, 2022 and Recent Weeks

• Entered into a clinical collaboration agreement with Merck (known as MSD outside the US and Canada) for the evaluation of Portage’s lead iNKT agonist, PORT-2, in combination with KEYTRUDA^® (pembrolizumab), Merck’s anti-PD-1 (programmed death receptor-1) therapy, for patients with first-line as well as PD-1 refractory NSCLC.
  • Under the terms of the collaboration, Merck will be providing KEYTRUDA for Portage Biotech’s IMPORT-201 trial, a Phase 1/2 clinical trial of PORT-2 for patients with NSCLC and advanced melanoma (also known as KEYNOTE E69). The two companies will establish a Joint Development Committee to optimally evaluate the trial’s combination arms.
• Presented updates from ongoing Phase 1/2 clinical trial of PORT-2 (IMM60) iNKT agonist for patients with NSCLC and advanced melanoma at the Society for Immunotherapy of Cancer’s 37^th Annual Meeting.
  • The poster presentation included updated data from the IMPORT-201 clinical trial, a multi-arm Phase 1/2 trial evaluating PORT-2 in multiple settings including first-line and refractory NSCLC and refractory melanoma, both as a monotherapy and in combination with Merck’s anti-PD-1 therapy, KEYTRUDA^® (pembrolizumab). The presented data builds on previous results shared at the 2022 American Society of Clinical Oncology (ASCO) meeting in June 2022.

Financial Results from Quarter Ended September 30, 2022

The Company generated a net loss and other comprehensive loss of approximately $1.1 million during the three months ended September 30, 2022 (the “Fiscal 2023 Quarter”), compared to a net loss and other comprehensive loss of approximately $2.9 million during the three months ended September 30, 2021 (the “Fiscal 2022 Quarter”), a decrease in loss of $1.8 million year over year. The principal reason for the decrease in net loss and other comprehensive loss was the net deferred income tax benefit of $2.5 million recognized in the Fiscal 2023 Quarter, compared to $0.5 million in the Fiscal 2022 Quarter. The principal components of the current year benefit were $2.2 million recognized with respect to the foreign currency effect on the deferred income tax liability settleable in foreign currency and the recognition of $0.3 million of current period losses generated during the Fiscal 2023 Quarter.

Operating expenses, which include research and development and general and administrative expenses, were $3.6 million in the Fiscal 2023 Quarter, compared to $3.3 million in the Fiscal 2022 Quarter, an increase of $0.3 million, which is discussed more fully below.

Research & development costs increased by approximately $0.2 million, or approximately 15%, from approximately $1.3 million in the Fiscal 2022 Quarter, to approximately $1.5 million in the Fiscal 2023 Quarter. The increase was attributable to clinical trial costs largely associated with the iNKT clinical trials in the Fiscal 2023 Quarter of $0.2 million. There were no such costs incurred in the Fiscal 2022 Quarter. Additionally, the Company incurred payroll-related expenses of $0.5 million in Fiscal 2023 Quarter, compared to $0.2 million in the Fiscal 2022 Quarter. The increase was attributable to increases in staff, as well as the formalization of a compensation program designed to be competitive in the market and attract and retain a strong management group. Additionally, the Company incurred costs of $0.03 million associated with the National Cancer Institute Collaboration Research and Development Agreement (CRADA program) in the Fiscal 2023 Quarter. These increases were partially offset by a reduction in non-cash share-based compensation expense with respect to stock options to purchase ordinary shares granted to employees, which was attributable to (a) the vesting over time of a portion of prior year grants; and (b) the decrease in the fair value of grants made in fiscal 2022.

General and administrative expenses increased by approximately $0.1 million, or approximately 5%, from approximately $2.0 million in the Fiscal 2022 Quarter, to approximately $2.1 million in the Fiscal 2023 Quarter. The principal reason for the increase was the $0.4 million increase in professional fees, of which approximately $0.1 million was attributable to legal fees associated with the acquisition of four pipeline candidates from the Tarus merger targeting the adenosine pathway and $0.2 million was attributable to stamp fees in the U.K. related to acquiring the outstanding minority interest of our iNKT agonist platform. Additionally, payroll-related expenses increased by $0.2 million due to the formalization of a compensation program adopted in the Fiscal 2023 Quarter. These increases were partially offset by a decrease in non-cash share-based compensation expense of $0.5 million attributable to the vesting of certain stock options granted in prior years and lower fair value associated with more recent grants, the decrease of $0.1 million associated with directors and officers insurance attributable to lower premiums under the policy.

As of September 30, 2022, the Company had approximately $15.0 million of cash and cash equivalents, reflecting settlement of the $3.0 million liabilities assumed with our acquisition of the adenosine pipeline during the Fiscal 2023 Quarter.
