Financial Summary:

For the year ended December 31^st :

Financial Highlights

For the year ended December 31, 2023;

• Total revenue decreased 6%, year over year.
• Cost of sales was $508,173 (47% of revenue) resulting in a gross margin of $562,134 (53% of revenue). In comparison, the cost of sales for the same period in 2022 was $510,395 (45% of revenue) resulting in a gross margin of $628,174 (55% of revenue). The gross margin decrease as a percentage of sales, year over year, is attributed to an increase in material costs and a write-down of obsolete inventory of $89,325 (2022 - $4,799).
• Selling expenses decreased to $278,866, from $301,359 for the same period in 2022, a 7% decrease. The decrease in selling expenses is a result of reduced spending in advertising (18%), and salaries (16%).
• Administrative expenses increased to $1,895,460 from $1,277,253 for the same period in 2022, a 48% increase. The increase in administrative expenses is attributed to increased spending on general and administrative expenses (80%) and director and advisory fees (34%).
• Stock based compensation expense increased 392% in 2022, due to the cumulative effect of accounting for the vesting of stock options granted in the current and previous years.
• Net research and development expenses for the Drug Division decreased to $2,938,245 from $4,113,741 for the same period in 2022, a 29% decrease. The decrease is primarily attributed to a decrease in the costs related to the manufacture of the Study Device and expenses for Study II patient enrollment and treatment.
• Net research and development expenses for the Device Division decreased to $43,828 from $167,365 for the same period in 2022, a 74% decrease.
• Net loss was $4,570,879, which included $933,790 of net non-cash expenses (i.e.: amortization, stock-based compensation expense and foreign exchange gain/loss). This compared to a net loss in 2022 of $5,235,302 which included $554,298 of net non-cash expenses, a 13% decrease. The Drug Division represented $4,058,764 of this loss (89%) in 2023. The decrease in net loss is attributed to decreased spending on research and development expenses in Study II.

Operational Highlights:

Non-Brokered Private Placement

On November 29, 2023, the Company closed a non-brokered private placement of Units. On closing, the Company issued an aggregate of 5,318,183 Units at a price of $CAN 0.22 per Unit for aggregate gross proceeds of approximately $CAN 1,170,000 of which 461,282 Units were purchased by certain insiders of the Corporation. Each Unit consists of one common share of the Company and one non-transferable Warrant. Each Warrant entitles the holder to acquire an additional Common Share at a price of $CAN 0.28 for a period of 5 years following the date of issuance.

On February 5, 2024, the Company closed a non-brokered private placement of Units. On closing, the Company issued an aggregate of 6,666,670 units at a price of $CAN 0.18 per Unit for aggregate gross proceeds of approximately $CAN 1,200,000, of which 1,310,502 units were purchased by certain insiders of the Corporation. Each Unit consists of one common share of the Company and one non-transferable Warrant. Each Warrant entitles the holder to acquire an additional Common Share at a price of $CAN 0.23 for a period of 5 years following the date of issuance.

Kristina Hachey CPA, Chief Financial Officer of Theralase® stated, "The 2023 annual financial statements are representative of the Company investing in the development of its lead asset, light-activated Ruvidar^TM, with a focus on commercializing the next standard of care treatment for BCG-Unresponsive NMIBC CIS. In 2024, the Company plans to secure funding through various equity and debt instruments to allow the Company the ability to become base shelf eligible. This will allow the Company sufficient funding to complete enrollment into Study II by year end, data lock in mid 2026 and position the Company for FDA and Health Canada approval the end of 2026."

Study II Update

On February 8 ^th , 2024, Dr. Michael Jewett joined the Company in the role of an independent consultant, to assist the Company in the accruement of patients into Study II. 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 assist Theralase® to complete enrollment and provide the primary study treatment to all 100 patients in Study II, by December 31, 2024.

To date, Study II has provided the primary study treatment for 63 patients, with new patients being enrolled in 2Q2024.

An advisory board meeting is scheduled to take place on April 12, 2024 during the Canadian Urologic Association ("CUA") Bladder Cancer Forum 2024 located in Toronto, Ontario to provide an update to all Canadian Principal Investigators ("PIs") of the Study II interim clinical data and to discuss opportunities for patient enrollment.

An advisory board meeting is scheduled to take place on May 4^th , 2024 during the 2024 American Urology Association ("AUA") meeting in San Antonio, Texas to provide an update to all Canadian and US-based PIs of the Study II interim clinical data and to discuss opportunities for patient enrollment.

Break Through Designation Update

The Company submitted a pre-Break Through Designation ("BTD") submission to the FDA in July 2023 and based on the FDA's feedback, the Company is currently working with the Clinical Study Sites ("CSSs"), a biostatistics organization and a regulatory organization to update the pre-BTD with clinical data clarifications identified by the FDA. The Company plans to resubmit the pre-BTD submission to the FDA in 2Q2024 for FDA review of these clarifications. Once the pre-BTD submission has been accepted by the FDA, the Company will compile a BTD submission for review by the FDA in support of the grant of a BTD approval.

Study II Preliminary Clinical Data :

Performance to Primary, Secondary and Tertiary Objectives

The Study II interim clinical data is demonstrating the following data:

For the primary objective, 64% of patients provided the Study Procedure (Study Drug activated by the Study Device) demonstrated a Complete Response ("CR") (negative cystoscopy and negative urine cytology). Including patients, who demonstrated an Indeterminate Response (" IR") (negative cystoscopy and positive or suspicious urine cytology), the Total Response ("TR") increases to 75%. This represents that 3 out of 4 Bacillus Calmette Guérin ("BCG")-Unresponsive Non-Muscle Invasive Bladder Cancer ("NMIBC") Carcinoma In-Situ ("CIS") patients treated with Theralase®'s unique Study Procedure are demonstrating complete destruction of their CIS bladder cancer within their bladders.

For the secondary objective, 35% (> 1 out of 3) patients demonstrated a duration of their CR for 15 months from date of first treatment.

For the tertiary objective, no patients have been diagnosed with a Serious Adverse Event ("SAE") directly related to the Study Drug or Study Device.

Clinical Data Based on Assessment Visit

The interim clinical data demonstrates that at the 90 Day Assessment, 56% of Evaluable Patients achieved a CR and 64% achieved a Total Response post primary Study II Treatment and at the 450 Day Assessment 38% achieved a CR and 40% achieved a TR.

Clinical Data Based on Assessment Visit for Patients Treated with the Optimized Study Procedure (Post August 1, 2020)

The above interim clinical data demonstrates that for patients who received the Optimized Study Procedure at the 90 Day Assessment visit, 61% of Evaluable Patients achieved a CR and 69% achieved a Total Response (CR + IR) post primary Study Procedure. At the 450 Day Assessment, 40% achieved a CR and 43% achieved a TR.

Note:

• For patients to be included in the statistical clinical analysis they must be enrolled in Study II, provided the primary Study Procedure and evaluated by a PI at the 90 day assessment visit (cystoscopy and urine cytology)
• One patient passed away prior to their 90 day assessment and is therefore not included in the efficacy statistical analysis, only in the safety statistical analysis; therefore, there are 63 patients that have been statistically analyzed for efficacy.
• Evaluable Patients are defined as patients who have been evaluated by a PI and thus excludes a patient's clinical data at specific assessment days, if that clinical data is pending.
• Two patients have been enrolled and provided the primary Study Procedure but, have not been evaluated at their 90 day assessment; therefore, 61 patients are considered Evaluable Patients at 90 days, with 52 patients considered Evaluable Patients at 450 days.
• The data analysis presented above should be read with caution, as the clinical data is interim in its presentation, as Study II is ongoing and new clinical data collected may or may not continue to support the current trends.
• For patients who have been removed from Study II by the PI or have elected to discontinue from the clinical study their Last Observation Carried Forward ("LOCF") has been used in this statistical analysis.

Patient Response Chart:

The Swimmer's plot below is a graphical representation of the interim clinical results (n=63) graphically demonstrating a patient's response to a treatment over time. As can be seen in the plot, clinical data is still pending for patients, who have demonstrated a CR and continue to demonstrate a duration of that response.

Swimmer's Plot:

The Swimmer's Plot illustrates:

• 18 Evaluable Patients achieved CR at each assessment date and thus achieved the primary and secondary objectives of Study II for all patients assessed up to 450 days (18/52 = 35%).
• 39 Evaluable Patients that achieved CR on at least one assessment date and thus achieved the primary objective of Study II (39/61 = 64%)

Kaplan-Meier Curve

The Kaplan-Meier ("KM") Curve represents the interim cumulative incidence of clinical events, including the treatment efficacy, occurring over prespecified time in Study II.

According to the interim clinical data in the KM curve:

• > 80% of patients remained in Study II after 90 days, following the initial Study Procedure.
• 39% of Total Response patients have a duration of response ≥ 450 days.
• 38% of Complete Response patients have a duration of response ≥ 450 days.

Serious Adverse Events

For 64 patients treated in Study II, there have been 13 Serious Adverse Events ("SAEs") reported:

• 2 - Grade 2 (resolved within 1 and 1 days, respectively)
• 7 - Grade 3 (resolved within 1, 2, 3, 4, 4, 82 and unknown days, respectively)
• 3 - Grade 4 (resolved within 3, 6 and 8 days, respectively)
• 1 - Grade 5

Theralase® believes all SAEs reported to date are unrelated to the Study II Drug or Study II Device, as reviewed and confirmed by an independent Data Safety Monitoring Board ("DSMB").

Note: A SAE is defined as any untoward medical occurrence that at any dose: Is serious or life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect or results in death.

Dr. Arkady Mandel, MD, PhD, DSc, Chief Scientific Officer of Theralase® stated, "The interim clinical data of Study II to date has proven to be world-class. Study II has demonstrated an ability to destroy urothelial cell carcinoma in a patient's bladder for a total response of 69% and a duration of that total response of 43%, for patients treated with the optimized Study Procedure. The primary benefits of the Theralase® technology versus competitive technologies are the high efficacy rates (patients achieve a CR in approximately 60% of the cases after only one Study Procedure), high duration of response and high safety margin (no SAEs directly associated with the Study Drug or Study Device); therefore, the Theralase® technology presents a safe, effective alternative therapy for patients, who are at risk of having their bladder removed."

About Study II:

Study II utilizes the therapeutic dose of the patented Study II Drug ("Ruvidar^TM" or "TLD-1433") (0.70 mg/cm²) activated by the proprietary Study II Device (TLC-3200 Medical Laser System or "TLC-3200"). Study II is focused on enrolling and treating approximately 100 BCG-Unresponsive NMIBC Carcinoma In-Situ ("CIS") patients in up to 15 Clinical Study Sites ("CSS") located in Canada and the United States.
