[{"type":"text","content":"Patient Five Cancer-Free Eighteen Months After Single Anti-Cancer TreatmentTORONTO, ON / ACCESSWIRE / July 31, 2019 / Theralase Technologies Inc. (“Theralase®” or the “Company”) (TSXV: TLT) (OTCQB: TLTFF), a clinical stage pharmaceutical company dedicated to the research and development of light activated Photo Dynamic Compounds (“PDCs”) and their associated drug formulations intended to safely and effectively destroy various cancers reports that patient five, enrolled and treated in the Phase Ib Non-Muscle Invasive Bladder Cancer (“NMIBC”) clinical study (“Study”), has demonstrated no tumour recurrence, progression or presence of NMIBC disease at the 540 day clinical and cystoscopy assessment.The Study’s purpose was to evaluate TLD-1433, Theralase’s lead PDC, for the primary endpoint of safety and tolerability, secondary endpoint of pharmacokinetics (movement and exit of drug within tissue) and exploratory endpoint of efficacy, primarily at 90 days and secondarily at 180 days post treatment.The Study was successfully completed with patient five and six demonstrating achievement of the primary, secondary and exploratory endpoints at 90 and 180 days, when treated with the Therapeutic Dose.Patient five has demonstrated no tumour recurrence, progression or presence of NMIBC disease at the 90, 180, 270, 360 and now 540 days post treatment clinical and cystoscopy assessment, marking a new achievement for the Company.Patient five and six were enrolled and treated in the Study at the Therapeutic Dose (0.70 mg/cm2). Theralase’s Anti-Cancer Treatment involved the intravesical instillation of a water-based solution of Theralase’s lead anti-cancer PDC, TLD-1433, via a catheter inserted through the urethra into the bladder of the patient, to allow the PDC to be preferentially absorbed by NMIBC tumours. The bladder was 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, comprising a Laser Emitter used to emit laser light and a proprietary Dosimetry System used to detect laser light, were then used to activate TLD-1433 resident in the NMIBC tumours.Shawn Shirazi, Ph.D., Chief Executive Officer - Drug Division of Theralase® stat...
