Sustained Therapeutics announces clinical trial of second product

Date Posted: 

Vancouver, BC - Sustained Therapeutics (the “Company”) announced today regulatory clearance for a pivotal Phase II/III human trial of its second product, a novel medication for the treatment of a rare form of cancer. Upper Tract Urethral Carcinoma (“UTUC”) is an orphan disease, a malignancy of the cells lining the renal pelvis. It affects about 6,000 patients each year in North America.

The Company’s product (“ST-02”) is delivered directly to the site of the carcinoma in the renal pelvis through a ureteric catheter, rather than via infusion or systemic delivery, and then releases slowly. Sustained Therapeutics believes that this delivery mechanism of its new product may provide benefits over current standard of care treatment for UTUC. ST-02 is based on Sustained Therapeutics’ proprietary sustained release platform technology.

This is an investigator sponsored trial (“IST”) being carried out by the Vancouver Prostate Centre (“VPC”) and supported by funding from the Canadian Institutes for Health Research. VPC has received a No Objection Letter (“NOL”) from Health Canada to conduct this study for ablation of urothelial carcinomas in the upper urinary tract. An initial 25 patients will take part in the study through the VPC and other sites across Canada, and if successful and subject to regulatory approval will be expanded to enroll an additional 50 patients across North America. The study will be led by Dr. Peter Black of the VPC.

“ST-02 has significant potential to treat this rare cancer, and the NOL from Health Canada is a very positive first step to evaluate this approach in this cancer, where surgical removal of the kidney is often the only effective treatment option,” says Dr. Martin Gleave, Sustained Therapeutics’ Chief Medical Officer and Distinguished Professor in the UBC Department of Urologic Sciences and Director of the VPC. “We are enabling rapid advancement of this therapy by running an Investigator Sponsored Trial (IST) and collaborating with talented colleagues like Dr. Peter Black at the VPC and others elsewhere.”

“ST-02 is designed for extended exposure in the renal pelvis, where the cancer is located, by coating the tissue and delivering chemotherapy for longer, right where it is needed. This is potentially a very important new development for patients suffering from UTUC,” confirms Mr. William Annett, Sustained Therapeutics’ Chief Executive Officer. “If successful, it demonstrates that our platform technology can be used for multiple different extended-release products.”
