Exhibit 99.1
Phio Pharmaceuticals Announces
Upcoming Presentation at the 39th
Annual Meeting of the Society for Immunotherapy of Cancer (SITC)
Presenting new clinical data from Phio’s on-going Phase 1b trial
MARLBOROUGH, Mass., Nov 7, 2024 (NEWSFILE) — Phio Pharmaceuticals Corp. (Nasdaq: PHIO) is a clinical-stage biotechnology company creating new pathways towards a cancer-free future by using its INTASYL® siRNA gene silencing technology designed to make the body’s immune cells more effective in killing cancer cells. Phio announced today that it is presenting clinical data from its on-going Phase 1b clinical trial at the 39th Annual Meeting of the Society for Immunotherapy of Cancer (SITC), which will be held in Houston, TX from November 8-10, 2024.
Phio’s presentation will highlight the clinical results from enrolled patients in Cohorts 1 and 2 in the Phase 1b dose escalation clinical trial. This clinical trial is designed to evaluate the safety and tolerability of intratumoral injection of PH-762 in patients with cutaneous squamous carcinoma, Merkel cell carcinoma and melanoma.
Clinical Results To Date
Intratumoral (IT) injection of PH-762 has been well tolerated in all patients enrolled in the trial to date. There were no related adverse events, no serious adverse events, and no dose limiting toxicities or dose adjustments. Five (5) patients with cutaneous carcinomas have enrolled in Cohorts 1 and 2. Each enrolled patient received four (4) IT doses of PH-762. The patients were diagnosed with cutaneous squamous cell carcinoma (4 patients) and metastatic melanoma (1 patient).
At Day 36 (tumor excision), while each patient in the first cohort had stable disease, the following results were described for two patients enrolled in the second cohort:
| · | Complete response (100% tumor clearance) reported for 1 patient with cutaneous squamous cell carcinoma; and |
| · | Partial response (90% tumor clearance) reported for 1 patient with cutaneous squamous cell carcinoma. |
The Phase 1b trial is on-going. Anticipated completion of the enrollment phase of this trial is Q3 2025.
“We are encouraged by the documented clinical and histopathological results observed to date,” said Mary Spellman MD, Phio's acting Chief Medical Officer. “Corresponding safety and tolerability data supports continued assessment of intratumoral PH-762 in patients with cutaneous carcinomas.”
Presentation Details are as follows:

About Phio Pharmaceuticals Corp.
Phio Pharmaceuticals Corp. (Nasdaq: PHIO) is a clinical-stage biotechnology company and a pioneer in the RNAi revolution advancing its proprietary INTASYL siRNA gene silencing technology to create new pathways towards a cancer-free future. INTASYL can target and silence virtually any gene with a high degree of specificity across a wide range of cell types and tissues. INTASYL is designed to enhance the ability of immune cells to more effectively kill tumor cells. INTASYL has also been used to enhance adoptive cell therapy. Notably, INTASYL is a self-delivering RNAi technology focused on immuno- oncology therapeutics without the need for formulation enhancements or manipulations to reach its target.
Phio’s lead clinical program, PH-762, is an INTASYL compound that silences PD-1. PH-762 is a potential non-surgical treatment for skin cancers. The on-going Phase 1b trial (NCT# 06014086) received FDA clearance for an Investigational New Drug Application to evaluate PH-762 in the treatment of cutaneous SCC, melanoma and Merkel cell carcinoma in the second quarter of 2023.
