Portage Biotech Announces Results for Fiscal Quarter Ended December 31, 2022

- Enrollment ongoing in IMPORT-201 Phase 1/2 trial of PORT-2 in Melanoma and Non-Small Cell Lung Cancer

- Company on track to initiate Phase 1 portion of ADPORT-601 trial by end of 2Q23

- Company to Host a Key Opinion Leader Event on Targeting Adenosine Pathway in Cancer

Portage Biotech Inc. (NASDAQ: PRTG), a clinical-stage immuno-oncology company advancing novel multi-targeted therapies for use as single agents and in combination, today announced financial results for the fiscal quarter ended December 31, 2022.

"During the quarter and in recent weeks we continued to progress our clinical programs. Building on the favorable data presented from our lead program – invariant natural killer T cell (iNKT) agonist, PORT-2 – at the 2022 annual meeting of the Society of Immunotherapy of Cancer (SITC), we announced a new clinical collaboration agreement with Merck to evaluate PORT-2 in combination with KEYTRUDA® (pembrolizumab)," said Dr. Ian Waters, Chief Executive Officer and Chairman of Portage Biotech. "We are expanding this trial internationally and are pleased to announce that our Investigational New Drug application is approved in the U.S., and we are activating U.S. sites. We anticipate establishing the recommended Phase 2 dose shortly and commencing the Phase 2 portion of the IMPORT-201 trial in the second quarter of 2023.

"We also are continuing to advance our company-sponsored ADPORT-601 adenosine trial for PORT-6 and PORT-7 in the U.S.," continued Dr. Walters. "This trial is designed to adapt over time and include safety and efficacy cohorts for these two agents alone and with other immune activating agents, including others from Portage's internal pipeline. The potential of our unique approach of enhancing immune response with next-generation small molecule adenosine inhibitors will be discussed in the Key Opinion Leader event we will be hosting on March 9. We look forward to building on the progress made during this past quarter, advancing our clinical programs, and presenting trial data at multiple congresses later this year."

Pipeline & Clinical Program Highlights for Fiscal Quarter Ended December 31, 2022 and Recent Weeks

• Presented updates from ongoing Phase 1/2 clinical trial of PORT-2 (IMM60) iNKT agonist for patients with non-small cell lung cancer (NSCLC) and advanced melanoma at SITC 37th 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 (programmed death receptor-1), KEYTRUDA® (pembrolizumab)
  • Data built on previous results shared at the 2022 American Society of Clinical Oncology (ASCO) meeting in June 2022 and presented additional safety and tolerability of PORT-2, along with the mechanistic potential to activate both the adaptive and innate immune systems and reduce the suppressive cells in the tumor microenvironment.
  • The presented data are available here .
    
    
• Entered into a clinical collaboration agreement with Merck for the evaluation of Portage's lead iNKT agonist, PORT-2, in combination with KEYTRUDA® (pembrolizumab), Merck's anti-PD-1 therapy, for patients with first-line as well as PD-1 refractory NSCLC.
  
  
• The Company will host a key opinion leader webinar on targeting the adenosine pathway in cancer on Thursday, March 9, 2023 at 10:30 am Eastern Time. Featuring Lawrence Fong, M.D., from The University of California, San Francisco (UCSF) Helen Diller Family Comprehensive Cancer Center, and Sumit Subudhi, M.D., Ph.D., from MD Anderson Cancer Center, this event will cover the immunologic rationale and current clinical landscape that set the foundation for Portage's development approach.

Financial Results from Quarter Ended December 31, 2022

The Company generated a net loss of approximately $7.5 million and other comprehensive loss of approximately $11.5 million during the three months ended December 31, 2022 (the "Fiscal 2023 Quarter"), compared to a net loss and other comprehensive loss of approximately $4.2 million during the three months ended December 31, 2021 (the "Fiscal 2022 Quarter"), an increase in net loss of $3.3 million and an increase in other comprehensive loss of $7.3 million.

Operating expenses , which include research and development ("R&D") and general and administrative ("G&A") expenses, were $4.8 million in the Fiscal 2023 Quarter, compared to $4.2 million in the Fiscal 2022 Quarter, an increase of $0.6 million, which is discussed more fully below.

R&D costs increased by approximately $0.6 million, or approximately 32%, from approximately $1.9 million in the Fiscal 2022 Quarter, to approximately $2.5 million in the Fiscal 2023 Quarter. The increase was primarily attributable to clinical trial costs of $0.6 million associated with the iNKT clinical trial and the start-up and manufacturing costs associated with the adenosine assets (PORT-6 and PORT-7) acquired in the Tarus acquisition of $0.8 million. There were no such costs incurred in the Fiscal 2022 Quarter. The Fiscal 2023 Quarter also included $0.1 million in other R&D costs relating to outside services and an increase in compensation of $0.1 million for consultants involved in R&D activities.   The Fiscal 2022 Quarter included $0.6 million for bonuses to employees and consultants, reflected in payroll-related expenses, which was approved and paid in the Fiscal 2022 Quarter. There was no such amount in the Fiscal 2023 Quarter. Additionally, the Fiscal 2022 Quarter included a higher amount of non-cash share-based compensation expense of $0.4 million, which was primarily attributable to (a) the continued vesting over time of grants; and (b) the decrease in the fair value of grants made after the Fiscal 2022 Quarter.

G&A expenses were substantially the same in the year-over-year periods, as they decreased by approximately $0.02 million, or approximately 0.9%, from approximately $2.24 million in the Fiscal 2022 Quarter, to approximately $2.22 million in the Fiscal 2023 Quarter. Professional fees increased by $0.2 million due to legal fees and audit related fees associated with the updating of public filings and payroll-related expenses increased by $0.3 million due to the continued build-up of the Company's infrastructure. The Fiscal 2023 Quarter also included director's fees of $0.1 million (director's fees were approved and commenced January 2022). 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 options granted in prior years and lower fair value associated with more recent grants and the decrease of $0.1 million associated with directors and officers ("D&O") insurance due to a decrease in the D&O premium market year-over-year.

The other principal components of the change in net loss and total comprehensive loss were as follows:

Other items of income and expense - Other items were substantially non-cash in nature and aggregated approximately $0.54 million net loss in the Fiscal 2023 Quarter, compared to approximately $0.08 million net income in the Fiscal 2022 Quarter, a change in other items of income and expense of approximately $0.62 million, quarter-over-quarter. The primary reason for the quarter-over-quarter difference in other items of income and expense was the difference in the fair value of warrants outstanding recognized in the quarter-over-quarter period, which expired in October 2022, and a loss from the change (increase) in fair value of the deferred purchase price payable – Tarus and deferred obligation – iOx milestone.

Net deferred income tax expense – Additionally, the Company reflected a net deferred income tax expense of $2.2 million in the Fiscal 2023 Quarter, compared to a net deferred income tax expense of $0.1 million in the Fiscal 2022 Quarter. The Fiscal 2023 Quarter includes the foreign currency effect on deferred tax liability balance settleable in British pound sterling of $2.5 million partially offset by the recognition of current period losses in the U.K. of $0.2 million and the related tax rate change effect of $0.1 million.

Fair value analysis – At December 31, 2022, the Company performed a fair value analysis of its investment in Intensity Therapeutics, Inc. ("Intensity") and determined the fair value was less than the its carrying value. Accordingly, the Company recognized an unrealized loss in value in Intensity of $4.046 million through other comprehensive income in the Fiscal 2023 Quarter.

As of December 31, 2022, the Company had cash and cash equivalents of approximately $13.1 million.
