Phio Announces New Appointments to Leadership Team,

Reports on Third Quarter 2022 Financial Results and

Provides Business Update


New executive team leading development of Phio’s RNAi compounds and proprietary INTASYL™ platform


Continuing enrollment in its Phase 1b study of PH-762 for the treatment of advanced melanoma


Additional studies demonstrate INTASYL’s activity against multiple protein targets including PD-1, BRD4, CTLA4, TIGIT and CTGF


MARLBOROUGH, Mass., November 10, 2022 /PRNewswire—Phio Pharmaceuticals Corp. (Nasdaq: PHIO), today announced new appointments to the leadership team, reported its financial results for the quarter ended September 30, 2022 and provided a business update. Phio is a clinical stage biotechnology company whose proprietary INTASYL™ technology makes immune cells more effective in killing tumor cells. INTASYL is the only self-delivering RNAi technology focused on immuno-oncology therapeutics.


The continuing enrollment in its first-in-human clinical study of PH-762 for advanced melanoma, along with recent positive data from four of its preclinical studies, has attracted new and industry-experienced executives to the Company. The new leadership team will join the current executive team to move the Company forward as it evolves its proprietary platform, INTASYL, from discovery to development.


The newly expanded leadership team is led by industry veteran Robert Bitterman, a member of the board of directors since 2012. Appointed Executive Chairman in September of this year, he assumed the duties leading all aspects of the Company’s operations. Mr. Bitterman brings 25 years of executive leadership experience in the pharmaceutical and biologic life science industry. He also has prior experience in senior financial and investor relations roles.


A key part of this new leadership team includes the appointment of Linda Mahoney as Vice President of Project Development, where she will lead the coordination of a multifunctional team to advance INTASYL compounds through the clinical development process. Ms. Mahoney is a pharmaceutical development executive with more than 25 years of experience in the industry. Previously, Ms. Mahoney was Vice President of Scientific Operations and Business Development at Cutanea Life Sciences, Inc. She also held positions in project management, product development and commercial supply chain at Sanofi-Aventis. Ms. Mahoney led numerous cross-functional pharmaceutical project teams through all stages of development, from product concept through commercialization.


Supporting the leadership team through the clinical development process is Dr. Mary Spellman, a board-certified dermatologist. Dr. Spellman will be working with the Company as a medical advisor and clinical development consultant. Dr. Spellman recently served as Chief Medical Officer at Castle Creek Biosciences, and prior to that at Menlo Therapeutics. She has contributed to the initiation of numerous Investigational New Drug applications, and to multiple drug and biologic marketing applications in a spectrum of clinical indications. Dr. Spellman is a Fellow of the American Academy of Dermatology, and currently is President of the Dermatologists in Industry organization. She is a former Associate Editor and now is a Reviewer for the Journal of the American Academy of Dermatology.







Phio’s business development activities will be supplemented by Michael Cozart, Managing Partner at LifeSci Consulting, LLC, a global strategy, consulting, and transaction advisory firm.


Recent Corporate Updates


·Phio’s research partner, Helmholtz Munich, presented preclinical data on Phio's lead clinical product PH-762, an INTASYL compound targeting PD-1, at the 9th Immunotherapy of Cancer (ITOC) annual meeting. PH-762 demonstrated increases in T cell population expressing stem-cell like characteristics. This increase in T cell population is expected to improve T cell persistence in vivo, therefore, resulting in enhanced duration of anti-tumor activity.
·At the 37th Annual Meeting of the Society for Immunotherapy of Cancer (SITC), Phio presented four posters demonstrating anti-tumor activity in preclinical models with our INTASYL compounds silencing the proteins BRD4, CTLA4, TIGIT and CTGF. Also, in preparation for an upcoming clinical trial in collaboration with our partner AgonOx, Inc., a poster demonstrating ability to manufacture clinical scale grade TIL with and without PH-762, our INTASYL compound targeting PD-1 was presented. An additional poster reported on the clinical trial design and update on the enrollment in our Phase 1b study of PH-762 for the treatment of advanced melanoma.


Upcoming Pipeline Milestones


·Plans to initiate a clinical trial evaluating the use of PH-762 and DP TIL in ACT during the fourth quarter of 2022 in partnership with AgonOx, Inc.
·Expects to finalize IND-enabling studies for PH-894 by year end 2022
·Expects to report top-line data from the first group of subjects with advanced melanoma in the clinical trial for PH-762 in the first quarter of 2023
·Additional data publications on the Company's pipeline programs


Financial Results


Cash Position


At September 30, 2022, the Company had cash of $14.5 million as compared with $24.1 million at December 31, 2021. The Company expects its current cash will be sufficient to fund currently planned operations for at least the next 12 months.


Research and Development Expenses


Research and development expenses decreased 6% to approximately $2.5 million for the quarter ended September 30, 2022, compared with approximately $2.7 million for the quarter ended September 30, 2021. The decrease in research and development expenses was primarily due manufacturing costs for PH-762 and PH-894 and the preclinical studies required for the Company’s PH-762 intratumoral clinical trial that were incurred in the prior year period offset by increases in research and development expenses for the preclinical studies required for the Company’s planned clinical trial with PH-894 conducted in the current year period.


General and Administrative Expenses


General and administrative expenses were approximately $1.1 million for the quarters ended September 30, 2022 and 2021 and were consistent quarter over quarter.


Net Loss


Net loss decreased 4% to approximately $3.6 million, or $0.26 per share, for the quarter ended September 30, 2022, compared with $3.7 million, or $0.28 per share, for the quarter ended September 30, 2021. The decrease in net loss was primarily attributable to the decrease in research and development expenses as described above.









INTASYL is the only self-delivering RNAi technology focused on immuno-oncology therapeutics. INTASYL compounds are chemically modified siRNA’s that provide efficient, spontaneous cellular uptake and potent, long lasting intracellular activity targeting a broad range of cell types and tissues. INTASYL drugs precisely target specific proteins that reduce the body’s ability to fight cancer, without the need for specialized formulations or drug delivery systems. In comparison to biologics and cell and gene therapies, INTASYL has a favorable non-clinical toxicity and safety profile, and a streamlined chemical synthesis that reduces costs and offers substantial convenience to the prescriber and patient.


PH-762 is an INTASYL compound that reduces the expression of PD-1, a protein that inhibits T cells’ ability to kill cancer cells. By suppressing PD-1, the T cells are re-activated to kill cancer cells. PH-762 is being developed as a standalone drug therapy (Direct-to-Tumor) and also in combination with adoptive cell therapy. PH-762 is in a Phase 1b study for the treatment of advanced melanoma.


PH-894 is an INTASYL compound that silences BRD4, a protein that controls gene expression in both T cells and tumor cells, thereby effecting the immune system as well as the tumor. What sets this compound apart is its dual mechanism: INTASYL PH-894 suppression of BRD4 in T cells results in T cell activation; additionally, suppression of BRD4 in tumor cells results in tumors becoming more sensitive to T-cell killing.


PH-804 is an INTASYL compound that targets TIGIT, a protein that inhibits the activity of Natural Killer (NK) cells. A recent study demonstrated that NK cells, when treated with PH-804, increased activation and enhanced the ability of NK cells to kill cancer cells.
