DR. MICHAEL JEWETT JOINS THERALASE(R) TO HELP COMPLETE ENROLLMENT IN THE PHASE II NON-MUSCLE INVASIVE BLADDER CANCER CLINICAL STUDY

Theralase Technologies Inc. has hired Dr. Michael Jewett as an independent consultant, to assist the company in the completion of enrolment of patients in the phase 2 bacillus calmette-guerin (BCG)-unresponsive non-muscle invasive bladder cancer (NMIBC) carcinoma in situ (CIS) clinical study (study 2).

Under the terms of the consulting agreement, Dr. Jewett will be responsible for working with existing clinical study sites, and helping to onboard new clinical study sites to allow Theralase to complete enrolment and provide the primary study treatment to all 100 patients in study 2, preferably by Dec. 31, 2024.

To date, Theralase has enrolled 63 patients in study 2.

If all 100 patients are enrolled in study 2 by the end of 2024/beginning of 2025, this will allow Theralase the opportunity to complete the primary follow-up of patients by mid-2026, and place the company in the coveted position for potential Health Canada and FDA (Food and Drug Administration) regulatory approval by end or 2026/beginning of 2027.

Dr. Jewett brings an impressive resume to Theralase, including being appointed to the Order of Canada in December, 2020, for his life-saving innovations in surgical oncology and for his advocacy of patient-centred clinical care. The Order of Canada is one of Canada's highest civilian honours, recognizing outstanding achievement, dedication to the community and service to the nation.

Dr. Jewett is a professor of surgery (urology) at the Princess Margaret Cancer Centre and at the University of Toronto, where he held the Farquharson Clinical Research Chair in Oncology.

Dr. Jewett has received awards from many cancer and urological associations, including the: International Society of Urology, Society of Urologic Oncology, American Society of Clinical Oncology, American Urological Association and Canadian Urology Association.

Roger DuMoulin-White, president and chief executive officer of Theralase, stated that: "I am delighted that Michael has accepted to join the company in his new role as an independent consultant to work with the clinical study sites, to complete enrolment and provide the primary study treatment to 100 patients in total in study 2 by the end of 2024. I strongly believe, under Michael's leadership and direction, that the company will be able to achieve this strategic objective. I look forward to working with him in his new capacity."

Dr. Arkady Mandel, chief scientific officer, stated that: "I look forward to working with Michael in his new role, as I believe the Theralase photodynamic therapy technology provides a therapy which is fast, safe and provides a significant duration of efficacy for patients afflicted with high-grade NMIBC, who face an unmet need. For patients diagnosed with BCG-unresponsive NMIBC CIS, the company recently reported an initial efficacy (clinical complete response) at any evaluated point in time of 64 per cent, with a duration of that efficacy of 36 per cent at 15 months. It is even more impressive that a majority of patients achieved these efficacy responses after only one Ruvidar treatment. Analyzing patients with a total response (cancer destroyed in the bladder, but cancer still detected in urine), the initial efficacy increased to 75 per cent and a duration of that efficacy of 40 per cent (43 per cent for patients who received the optimized treatment) at 15 months. These are very strong efficacy numbers for this patient population. The high safety profile is also appealing, as there have been no serious adverse events directly related to the study drug or study device."

Dr. Jewett stated that: "I am delighted to be working with the Theralase team again, as I was actively involved in both the phase 1b clinical study and the commencement of study 2. I strongly believe in the safety and efficacy of the Theralase technology in effectively treating patients diagnosed with BCG-unresponsive NMIBC CIS. The Theralase technology, in a majority of cases, involves only one treatment versus months of therapy with immunotherapy and/or chemotherapy drugs, and has only mild to moderate side effects that are easily managed and often resolve in days. I am impressed that a Canadian-based technology has the potential to make a significant impact on the world stage."
