Phio Pharmaceuticals Corp. reports developments as a clinical-stage siRNA biopharmaceutical company advancing its proprietary INTASYL® gene-silencing technology for immuno-oncology. Company updates center on PH-762, an INTASYL compound designed to silence the PD-1 gene and evaluated as an intratumoral therapy for cutaneous squamous cell carcinoma, melanoma and Merkel cell carcinoma.
Recurring news themes include PH-762 clinical results, safety and pathology data, nonclinical toxicology work, cGMP clinical-supply manufacturing, regulatory-development steps, financial results, equity financing activity and investor presentations. Coverage also reflects the company's use of self-delivering RNAi technology intended to enhance immune-cell activity against tumor cells without specialized formulation or delivery systems.
Phio Pharmaceuticals Corp. (Nasdaq: PHIO) reported financial results for Q1 2021, highlighting strong momentum in its pipeline. The company has significant data supporting its INTASYL compounds, showing potential to enhance CAR-T therapy efficacy. A clinical study for PH-762 in advanced melanoma is set to commence in Q4 2021, conducted at the Gustave Roussy Institute. Cash reserves reached $32.7 million, sufficient to fund operations into Q2 2023, despite a net loss of $3.4 million for the quarter. R&D expenses rose to $2.6 million, reflecting increased preclinical study costs.
Phio Pharmaceuticals Corp. (Nasdaq: PHIO) announced promising in vivo data on May 11, 2021, indicating that its compound PH-762 significantly boosts the antitumor efficacy of HER2-targeted CAR-T cells against solid tumors, particularly in a mouse model of ovarian cancer. The results show approximately 90% PD-1 silencing in HER2CART cells, enhancing their effectiveness without affecting cell viability. This breakthrough could improve T cell-based immunotherapies, addressing challenges faced by traditional CAR T-cell therapies in solid tumors.
Phio Pharmaceuticals Corp. (Nasdaq: PHIO) announced new data presentations at the upcoming 24th Annual Meeting of the ASGCT (May 11-14, 2021) and the ASCO Annual Meeting (June 4-8, 2021). At ASGCT, the poster titled "INTASYL PH-762 Self-Delivering RNAi Targeting PD-1 Enhances the Therapeutic Efficacy of HER2-Targeted CAR-T Cells" will be presented by Benjamin Cuiffo et al. Additionally, ASCO will feature a poster on INTASYL therapy targeting BRD4 and PD-1. Archived presentations will be available on the company's website.
Phio Pharmaceuticals Corp. (Nasdaq: PHIO) announced promising new in vivo data indicating that its INTASYL (mPH-762) therapy achieves significant tumor growth inhibition through intratumoral administration in both PD-1 responsive and refractory cancer models. This method shows potential for enhanced local immune checkpoint blockade without the systemic side effects of traditional therapies. The company plans to initiate a first-in-human clinical study for mPH-762 in advanced melanoma by Q4 2021, showcasing its commitment to advancing innovative cancer treatments.
Phio Pharmaceuticals Corp. (Nasdaq: PHIO) reported a net loss of $8.8 million for 2020, a slight improvement from $8.9 million in 2019.

Developmental progress includes new collaborations with AgonOx, Inc. and plans to initiate two clinical studies for PH-762 in 2021. R&D expenses rose to $4.4 million, while G&A expenses decreased to $4.4 million, reflecting reduced legal and hiring costs. Overall, the company maintains a solid financial outlook for the next two years.
Phio Pharmaceuticals Corp. announced new study data on its product candidate, PH-762, which targets PD-1 and shows promise in tumor control. This presentation will be part of the AACR Annual Meeting 2021, held virtually from April 10-15 and May 17-21. The poster titled "Intratumoral INTASYL™ self-delivering RNAi targeting PD-1" will explore the treatment's effects similar to systemic anti-PD-1 antibodies. Further details will be available on the Company’s website after the presentation.
Phio Pharmaceuticals Corp. has entered a clinical collaboration with AgonOx, Inc. to advance T cell-based cancer immunotherapies utilizing PH-762 and AgonOx's DP tumor-infiltrating lymphocyte (TIL) technology. The collaboration aims to enhance TIL therapeutic efficacy, with a clinical study expected to enroll patients later this year. Preclinical data suggests PH-762 significantly boosts the tumor-killing activity of CD8 DP TILs. AgonOx will receive financial support for the trial, while Phio stands to gain from future development milestones and royalties.
