--Six sites across the U.S. are now engaged in Phase1b study
Marlborough, Massachusetts--(Newsfile Corp. - November 19, 2024) - Phio Pharmaceuticals Corp. (NASDAQ: PHIO), a clinical stage biotechnology company exploring new pathways towards a cancer-free future, today announced it has completed the enrollment of its second patient cohort in its PH-762 Phase 1b dose-escalating clinical trial, and added a sixth clinical site in San Diego, CA.
Phio recently presented new data from the ongoing clinical trial showing that, of the two patients who have completed treatment in the second dose cohort, one patient with cutaneous squamous cell carcinoma achieved a complete response (100% tumor clearance) while a second patient with squamous cell carcinoma achieved a partial response (90% tumor clearance).
The new clinical trial site, Paradigm Clinical Research Centers in San Diego, CA joins five other sites across the country:
- Banner MD Anderson Cancer Center in Gilbert, Arizona
- The George Washington University-Medical Faculty Associates in Washington, D.C.
- The University of Pittsburgh Medical Center (UPMC)-Department of Dermatology, Pittsburgh, PA
- Integrity Research Clinical Associates in Delray Beach, Florida
- Centricity Research in Dublin, Ohio
"We are pleased with enrollment completion of the second dose cohort and the encouraging patient outcomes in the first two patients in this cohort," said Robert Bitterman, CEO of Phio Pharmaceuticals.
Phio develops therapeutics that use its proprietary INTASYL® siRNA gene silencing technology designed to make immune cells more effective in killing cancer cells. PH-762 is an INTASYL compound that silences PD-1, a protein that inhibits T cells' ability to kill cancer cells. The Phase 1b trial is a dose escalation study for our lead product candidate, PH-762, in adult patients with cutaneous squamous cell carcinoma, melanoma, or Merkel cell carcinoma. The study is designed to evaluate the safety and tolerability of neoadjuvant use of intratumorally injected PH-762, assess the tumor response, and determine the dose or dose range for continued study of PH-762 in patients with cutaneous squamous cell carcinoma, melanoma, or Merkel cell carcinoma.
More information about this clinical trial is available at clinicaltrials.gov (identifier: NCT06014086).
