Researchers pinpoint tumor-related protein, slow progression of cancers

medicalxpress | April 17, 2019

Locking a biochemical gate that admits fuel into immune-suppressing cells could slow tumor progression and assist the treatment of multiple cancers, says new research from the Wistar Institute, the University of Nebraska-Lincoln and others. Published April 17 in the journal Nature, the study found elevated levels of fatty acid transporter protein 2, or FATP2, in a type of cell known to muffle immune responses and impede cancer therapies. After isolating tumorous cells from humans and mice, the researchers also discovered substantially higher numbers of an energy-granting lipid that FATP2 helps produce and traffic into cells. Collectively, the study's findings implicate FATP2 in maliciously rewiring the body's most common white blood cells, which otherwise act as first responders in fighting infections. When the researchers knocked out a gene linked to FATP2, they found that the tumors of several cancers—lymphoma, lung carcinoma, colon carcinoma and pancreatic cancer—grew markedly slower in mice. Administering the FATP2-inhibiting compound Lipofermata—identified by Nebraska's Concetta DiRusso in the mid-2000s—likewise helped slow and even reject tumors when paired with a drug that disrupts cellular replication. The study suggests that targeting FATP2 in the immune-suppressing cells could block the resulting buildup of lipids and mitigate tumor progression without significant side effects, the team said.

Phio Pharmaceuticals Announces New Clinical Program to Study PH-762 for the Treatment of Cutaneous Squamous Cell Carcinoma

Phio Pharmaceuticals Corp. | December 22, 2022

Phio Pharmaceuticals Corp., today announced it expects to file an IND in the US in the first half of 2023 for a Phase 1b clinical trial of its INTASYL™ compound, PH-762. Phio is a clinical stage biotechnology company whose proprietary INTASYL self-delivering RNAi technology is designed to make immune cells more effective in killing tumor cells. PH-762 has been shown to reduce the expression of PD-1, a protein that inhibits T cells' ability to kill cancer cells. When administered intratumorally in preclinical models PH-762 primes an anti-tumor immune response, and inhibits tumor growth. Phio is currently conducting a Phase 1b clinical trial of PH-762 for the treatment of advanced melanoma at the Gustave Roussy Institute, one of the largest cancer centers in Europe. Phio expects to commence a US Phase 1b clinical trial early in the 2nd half of 2023. The initial US trial is expected to focus on the treatment of cutaneous squamous cell carcinoma and other selected cutaneous malignancies, following successful regulatory review of the IND. "Therapeutic interventions for cSCC are limited, and there is increasing unmet medical need. As cSCC tumors comprise approximately 51% of the total incidence of solid tumors in the US, excluding basal cell cancers, we recognize the growing need for alternative therapies for cSCC," said Robert Bitterman, Phio's Principal Executive Officer and Executive Chairman. Mr. Bitterman has over 25 years of executive leadership experience in the pharmaceutical and biologic life science industry with a proven track record in operations, finance and investor relations. "While monoclonal antibody therapies are available for the treatment of cSCC, mechanistically they only block the interaction between PD-1 and PD-L1 on the cell surface. PH-762 also has the potential to address PD-1 inside the T cell, essentially further enhancing the activity of the T cell to kill the tumor cells," said Dr. James Cardia, Phio's Vice President of Scientific Operations. Dr. Cardia led the team that discovered INTASYL. "PH-762 has the potential to meet a significant medical need in patients who have failed to respond to mAbs, as well as those with resectable and metastatic solid tumors. Phio is committed to advancing the study of PH-762 to provide a meaningful therapy for patients with a broad range of solid tumors." Dr. Mary Spellman, Phio's Medical and Clinical Development Advisor About INTASYL INTASYL compounds are chemically modified siRNAs that are designed to 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. INTASYL has demonstrated preclinical efficacy in both Direct-to-Tumor and Adoptive Cell Therapy applications. In comparison to biologics and cell and gene therapies, INTASYL has a favorable pre-clinical toxicity and safety profile, and a streamlined chemical synthesis that reduces costs and offers substantial convenience to the prescriber and patient. Phio believes that INTASYL is the only self-delivering RNA interference technology focused on immuno-oncology therapeutics.
