("Theralase®" or the "Company") (TSXV:TLT) (OTCQB:TLTFF), a clinical stage pharmaceutical company dedicated to the research and development of light and/or radiation activated Photo Dynamic Compounds ("PDCs") for the safe and effective destruction of various cancers, bacteria and viruses has released the Company's 3Q2023 unaudited condensed interim consolidated Financial Statements ("Financial Statements").

Financial Summary:

For the nine-month period ended September 30^th:

¹ Other represents foreign exchange, interest accretion on lease liabilities and / or interest income

Financial Highlights for the Nine-Month Period Ended September 30^th, 2023:

Total revenue decreased 13%, year over year.

Cost of sales for the nine-month period ended September 30^th, 2023 was $363,882 or 51% of revenue resulting in a gross margin of $342,813 or 49% of revenue. In comparison, the cost of sales for the same period in 2022 was $389,232 or 48% of revenue resulting in a gross margin of $423,766 or 52% of revenue. Cost of sales is represented by the following costs: raw materials, subcontracting, direct and indirect labour and the applicable share of manufacturing overhead.

The gross margin decrease, as a percentage of sales, year over year, is primarily attributed to an increase in material costs.

Selling expenses for the six-month period ended September 30^th, 2023 decreased to $194,418 from $238,904 for the same period in 2022, a 19% decrease. The decrease in selling expenses is a result of reduced advertising (24%) and salaries (25%).

Administrative expenses for the nine-month period ended September 30^th, 2023, increased to $1,456,382 from $1,060,980 for the same period in 2022, a 36% increase. The increase in administrative expenses is primarily attributed to increased spending on general and administrative expenses (82%) and director and advisory fees (35%). Stock based compensation expense increased 319% from 2022 due to an increase in stock options granted.

Net research and development expenses for the nine-month period ended September 30^th, 2023, decreased to $2,250,546 from $3,330,705 for the same period in 2022 for the Drug Division, a 32% decrease and decreased to $34,844 from $133,959 for the same period in 2022 for the Device Division, a 74% decrease. The decrease in research and development expenses, for the Drug Division, is primarily attributed to the costs related to the manufacture of the Study II Drug. The decrease in research and development expenses, for the Device Division, is primarily attributed to the costs related to the manufacture of the Study II Device. Research and development expenses represented 58% of the Company's operating expenses and represent investment into the research and development of the Company's Drug Division Anti-Cancer Therapy ("ACT") technology.

The net loss for the nine month period ended September 30^th, 2023, was $3,579,855, which included $714,020 of net non-cash expenses (i.e.: amortization, stock-based compensation expense and foreign exchange gain/loss). This compared to a net loss for the same period in 2022 of $4,352,101, which included $391,321 of net non-cash expenses. The Drug Division represented $3,123,435 of this loss (87%) for the nine month period ended September 30^th, 2023. The decrease in net loss is primarily attributed to decreased spending on research and development expenses in Study II.

Operational Highlights:

Non-Brokered Private Placement

On September 7, 2023, the Company completed a financing by way of a non-brokered private placement, where 1,840,000 units were issued at a price of $CAN 0.25 per unit for gross proceeds of $CAN 460,000.

Each Warrant entitles the holder to acquire an additional Common Share at a price of $0.28 for a period of 5 years following the date of issuance.

Break Through Designation Update

The Company has submitted a pre-BTD submission to the FDA 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 early 1Q2024 for FDA review of these clarifications. Once the pre-BTD submission has been accepted by the FDA, the Company plans to compile a BTD submission for review by the FDA in support of the grant of a BTD approval in 1Q2024.

Study II Preliminary Clinical Data:

To date, Study II has provided the primary study treatment for 63 patients.

Performance to Primary, Secondary and Tertiary Objectives

Study II Clinical Data Based on Assessment Visit

The interim clinical data demonstrates that at the 90 Day Assessment 58% of Evaluable Patients achieved a CR and 65% achieved a Total Response (CR + IR) post primary Study II Treatment and at 450 days 35% achieved a CR and 40% achieved a TR.

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

The interim clinical data demonstrates that at the 90 Day Assessment 64% of Evaluable Patients achieved a CR and 71% achieved a Total Response (CR + IR) post primary Study II Treatment with the Optimized Study II Treatment and at 450 days 36% achieved a CR and 42% 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 II Treatment 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 statistical analysis; therefore, there are 63 patients that have been statistically analyzed.
• 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.
• Five patients have been enrolled and provided the primary Study II Treatment, but have not been evaluated at their 90 day assessment; therefore, 57 patients are considered Evaluable Patients at 90 days, with 43 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, with significant data still pending.
• For patients who have been removed from the study 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 an initial CR at 90 days and continue to demonstrate a duration of that response.

Swimmer's Plot:

The Swimmer's Plot illustrates:

• 15 Evaluable Patients that achieved CR at each assessment date (with one patient under PI review with a NR at the 270 and 360 assessment dates) and thus achieved the primary and secondary objectives of Study II for all patients assessed up to 450 days (15/43 = 35%).
• 38 Evaluable Patients that achieved CR on at least one assessment date and thus achieved the primary objective of Study II (38/57 = 67%)

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 II Treatment.
• 46% of Total Response patients have a duration of response ≥ 450 days.
• 40% of Complete Response patients have a duration of response ≥ 450 days.

Serious Adverse Events

For 63 patients treated in Study II, there have been 11 Serious Adverse Events ("SAEs") reported:

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