(Nasdaq: PHIO), a biotechnology company developing the next generation of immuno-oncology therapeutics based on its proprietary self-delivering RNAi (INTASYL™) therapeutic platform, today reported its financial results for the quarter ended September 30, 2020 and provided a business update.

"During the quarter, we continued to execute on the development of our INTASYL RNAi technology as a cancer immunotherapy platform for innovative therapeutics. Promising new in vivo data was recently presented at the Society for Immunotherapy of Cancer's (SITC) annual meeting. This data showed that our INTASYL compounds targeting PD-1, PD-L1 or TIGIT inhibited tumor growth, and that such antitumoral effect can be significantly improved by combining different INTASYL compounds without having a negative impact on the tolerability of the treatment," said Dr. Gerrit Dispersyn, President and CEO of Phio. "Immune checkpoint therapy with systemic antibodies can result in dose limiting toxicities, especially when used in combination. With our INTASYL platform, we can easily combine multiple targets in a single therapeutic. Our data suggest that local administration with INTASYL compounds, even when used in combination, may provide a safer and more cost-effective alternative to antibody-based immune checkpoint therapy. Based upon these exciting results, we look forward to finalizing our IND-enabling studies and to moving our INTASYL compounds into the clinical phase of development in the near future."

Quarter in Review and Recent Corporate Updates

• Presented data at the AACR Virtual Annual Meeting II on PH-804, an INTASYL compound targeting TIGIT, inhibiting tumor growth and conferring an inflammatory tumor microenvironment.
• Presented data at SITC 2020 showing that the antitumoral efficacy of our PH-762, PH-790 and PH-804 INTASYL compounds can be further improved by combining them in a single drug treatment.
• Collaborated on poster presentations featuring INTASYL RNAi technology by two development partners, AgonOx, Inc. and the Helmholtz Zentrum München that were presented at SITC 2020.
• Attended and presented at the H.C. Wainwright 22^nd Annual Global Investment Conference.
• Conducted preclinical work to support the planned initiation of clinical trials with PH-762.
• Ended the quarter with total cash of approximately $16.9 million as of September 30, 2020.

Financial Results

Cash Position

At September 30, 2020, the Company had cash of $16.9 million as compared with $6.9 million at December 31, 2019. The Company expects its cash will be sufficient to fund currently planned operations for at least the next 12 months.

Research and Development Expenses

Research and development expenses were approximately $1.3 million for the quarter ended September 30, 2020, compared to approximately $1.0 million for the quarter ended September 30, 2019. The increase is primarily due to an increase in the use of third-party service providers to conduct preclinical research studies to support the development of the Company's pipeline programs as compared to the prior year period offset by a decrease in the use of an outside interim temporary labor consultant in the prior year period.

General and Administrative Expenses

General and administrative expenses were relatively steady at $1.1 million for the three-month periods ended September 30, 2020 and 2019.

Net Loss

Net loss was $2.3 million, or $0.40 per share, for the quarter ended September 30, 2020, compared with $2.1 million, or $4.53 per share, for the quarter ended September 30, 2019. The increase in net loss was primarily attributable to an increase in research and development expenses, as discussed above. The change in net loss per share was primarily due to an increase in the number of shares outstanding as a result of our capital raise activities as compared to the prior year period.
