TORONTO, ON / ACCESSWIRE / May 13, 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 PhotoDynamic Compounds ('PDC') and their associated drug formulations intended to safely and effectively destroy various cancers announced that Theralase recently met with its Medical and Scientific Advisory Board ('MSAB'), as well as potential Principal Investigators ('PIs'), who are interested in participating in the Phase II Non-Muscle Invasive Bladder Cancer ('NMIBC') clinical study ('ACT-NMIBC').

The meeting focused primarily on the presentation of the clinical endpoints achieved in the successfully completed Phase Ib NMIBC clinical study, as well as a discussion on the design and FDA regulatory requirements pertaining to the ACT-NMIBC.

The FDA provided guidance to the industry in February 2018, entitled, 'BCG-Unresponsive Nonmuscle Invasive Bladder Cancer: Developing Drugs and Biologics for Treatment Guidance for Industry'.

In the guidance, the FDA stated that, 'In BCG-unresponsive NMIBC, a single-arm clinical trial with complete response rate and duration of response as the primary endpoint can provide primary evidence of effectiveness to support a marketing application.' 1

Theralase's primary question to be discussed with the FDA during a pre-Investigational New Drug ('pre-IND') conference call to be held in early 3Q2019 will be 'If Theralase's ACT-NMIBC demonstrates a Complete Response ('CR') at 90 days and a duration of that CR of 30% or more at 360 days post primary treatment, would this be sufficient to support a marketing application in the opinion of the FDA?'

The PIs at the meeting consisting of leading Canadian, US and international uro-oncologists, were presented with the opportunity to learn more about Theralase's TLD-1433-based PhotoDynamic Therapy ('PDT') and its application to BCG-Unresponsive NMIBC.

Dr. Shawn Shirazi, CEO-Drug Division, Theralase stated, 'Theralase stakeholders should be excited about the ability of the Company to execute on its strategic objectives, from successfully completing the Phase Ib NMIBC clinical study to the commencement of the ACT-NMIBC study. The Company is focusing on opening Canadian, US and international study sites throughout Q2 2019 and Q1 2020 with the PIs that attended the 5th annual MSAB meeting. The overall response of the PIs was extremely encouraging, with the MSAB and PIs recognizing the hard work and dedication of the Theralase team in the execution of its clinical development strategy to advance a viable treatment to potential commercialization for BCG-Unresponsive NMIBC.'

About Phase Ib Study

Theralase's Phase Ib NMIBC clinical study successfully achieved the: primary endpoint of safety and tolerability, secondary endpoint of pharmacokinetics (movement and exit of TLD-1433 within the body) and exploratory endpoint of efficacy. The study results have shown a strong efficacy signal with a 66% CR in the Therapeutic Dose Group (0.70 mg/cm2) after only a single PDT treatment, with patients 5 and 6 demonstrating no presence, recurrence or progression of the disease, 360 days post treatment.

About Phase II Study

The ACT-NMIBC clinical study will utilize the Therapeutic Dose (0.70 mg/cm2) of TLD-1433 and will focus on the treatment of approximately 100 to 125 BCG-Unresponsive NMIBC patients in approximately 20 clinical study sites located in Canada, the US and internationally, with a primary endpoint of efficacy and a secondary endpoint of safety.

The primary endpoint will be evaluated by:

CR in patients with Carcinoma In-Situ ('CIS') with or without resected papillary disease at 90 days post-treatment with a duration of CR evaluated at 360 days post-treatment.
Patient CR is defined as at least one of the following:

1) Negative cystoscopy and negative (including atypical) urine cytology

2) Positive cystoscopy with biopsy-proven benign or low-grade NMIBC

3) Negative cystoscopy with malignant urine cytology, if cancer is found in the upper tract or prostatic urethra and random bladder biopsies are negative

The secondary endpoint will be evaluated by:

Incidence and severity of Adverse Events ('AEs') Grade 4 or higher that do not resolve within 360 days post-treatment; whereby:

Grade 1 = Mild, Grade 2 = Moderate, Grade 3 = Severe, Grade 4 = Life-threatening or disabling, Grade 5 = Death
