Financial Results and Corporate Highlights

·Dr. John A. Barrett Appointed as Chief Development Officer
·Reiterates Cash Expected to Provide Funding Into Second Half of 2020


MARLBOROUGH, Mass., May 14, 2019 /PRNewswire/

- Phio Pharmaceuticals Corp. (NASDAQ: PHIO), a biotechnology company developing the next generation of immuno-oncology therapeutics based on its proprietary self-delivering RNAi (sd-rxRNA®) therapeutic platform, today reported its financial results for the first quarter ended March 31, 2019 and provided a business update.


“Our financial results during the first quarter of the year continue to remain consistent and in line with our projections for 2019. With an approximate $2 million quarterly cash burn expected to continue for the remainder of the year, the Company expects to have funding into the second half of 2020 while also providing us with the ability to significantly advance and expand our pipeline projects. In parallel with progressing our lead pipeline products, we have expanded our collaborations to include a collaboration with Glycostem Therapeutics and have increased our data output supporting the broad applicability of our self-delivering RNAi platform in various immune cell types and immuno-oncology applications, such as adoptive cell therapy and direct intra-tumoral use of our products,” said Dr. Gerrit Dispersyn, President and CEO of Phio Pharmaceuticals Corp. “By bringing new talent on board and implementing improved R&D processes, we look forward to further accelerating our R&D efforts within the financial expectations and projected cash runway.”


Quarter in Review and Recent Corporate Updates




oAppointed Gerrit Dispersyn, Dr. Med. Sc. as the Company’s President and Chief Executive Officer. Dr. Dispersyn succeeded Geert Cauwenbergh, Dr. Med. Sc., who retired as CEO of the Company and remains as a member of the Company’s Board of Directors.


oAppointed John A. Barrett, Ph.D. as the Company’s Chief Development Officer. Dr. Barrett joins Phio from Ziopharm Oncology, Inc. where he served as the company’s Vice President of R&D and Translational Medicine. He has accumulated over 25 years of experience working in research and development and is an expert in developing cell-based immuno-oncology therapies. Dr. Barrett will lead the development and execution of the Company’s preclinical and clinical strategy for our product candidates.


·Entered into a research collaboration with Glycostem Therapeutics BV to explore the potential synergies of using our sd-rxRNA in combination with Glycostem's proprietary Natural Killer-cell (NK-cell) generation technology (oNKord®). The goal of the collaboration is to develop cellular immunotherapies for cancer treatment with enhanced efficacy and/or safety, resulting in further improvement of Glycostem’s cellular immunotherapies for the treatment of cancer patients.


·Presented a poster titled “Feasibility and efficacy using self-delivering RNAi against TGFB1 to reduce TME immunosuppression” at the American Association for Cancer Research (AACR) Annual Meeting 2019.


oData from the poster demonstrated that an sd-rxRNA targeting TGFB1 was efficiently taken up by cancer and immune cells resulting in downregulation of target gene expression. The data further showed that intra-tumoral injection of sd-rxRNA targeting TGFB1 can reduce the immunosuppressive tumor microenvironment and potentially boost immune effector cell activity. Future clinical development activities will explore the possible synergistic effects of this approach in combination with adoptive cell therapy or other oncology therapies.


·On May 14, 2019, the Nasdaq Stock Market provided written notice and granted the Company an additional 180 calendar days, or until November 11, 2019, to regain compliance with the minimum bid price requirements set forth in the Nasdaq listing rules. The written notice has no effect on the listing of the Company’s common stock at this time.






Select Financial Results


Cash Position


At March 31, 2019, the Company had cash of $12.7 million as compared with $14.9 million at December 31, 2018. The Company expects its cash to provide funding into the second half of 2020.


Research and Development Expenses


Research and development expenses for the quarter ended March 31, 2019 were $1.1 million as compared with $1.4 million for the quarter ended March 31, 2018. The decrease was primarily due to a reduction in headcount and the payroll-related expenses, as well as the completion of the Company’s drug manufacture of RXI-762 in the prior year period.


General and Administrative Expenses


General and administrative expenses for the quarter ended March 31, 2019 were $1.1 million as compared with $0.9 million for the quarter ended March 31, 2018. The increase was primarily due to an increase in stock-based compensation expense related to the restricted stock issued to the Company’s former Chief Executive Officer in lieu of cash compensation.


Net Loss


Net loss for the quarter ended March 31, 2019 was $2.1 million, compared with $2.2 million for the quarter ended March 31, 2018. The decrease was primarily due to changes in operating expenses, as discussed above.
