Theralase® Anti-Cancer Technology Used to Treat Fifth Patient for Bladder Cancer
Toronto, Ontario – January 18, 2018
Theralase Technologies Inc. (“Theralase®” or the “Company”) (TLT: TSXV) (TLTFF: OTC), a leading biotech company focused on the commercialization of medical devices to eliminate pain and when used in conjunction with Photo Dynamic Compounds (“PDCs”) to destroy cancer, announced today that the fifth patient in a Phase Ib Non-Muscle Invasive Bladder (“NMIBC”) clinical study (“Study”) was enrolled and treated on January 10, 2018, using the Company’s anti-cancer Photo Dynamic Therapy (“PDT”) technology.
The anti-cancer PDT treatment procedure involves the instillation of a water based solution of Theralase’s lead anti-cancer PDC, TLD-1433, through the urethra into the bladder of the patient, to allow the PDC to be preferentially absorbed by NMIBC tumours. The bladder is then drained of the solution, flushed with sterile water to remove non-absorbed solution and refilled with sterile water via a cystoscope. A fibre optic assembly, known as a Dosimetry Fibre Optic Cage (“DFOC”) with the ability to both emit and detect laser light, is inserted through the cystoscope, to activate the absorbed PDC, for the intended destruction of the NMIBC tumours.
The Study is being used to evaluate TLD-1433 for the primary endpoint of safety and tolerability, a secondary endpoint of pharmacokinetics (movement and exit of drug within tissue) and an exploratory endpoint of efficacy.
Three patients have been enrolled and treated at the Maximum Recommended Starting Dose (0.35 mg/cm2). Two patients have been enrolled and treated at the Therapeutic Dose (0.70 mg/cm2), with an additional four patients remaining to be enrolled and treated at the Therapeutic Dose to complete the Study.
If Health Canada regulatory approval of the Study is achieved, subject to Health Canada and FDA regulatory approval, the Company plans to commence a multi-center Phase II NMIBC clinical study, with a primary endpoint of efficacy.
