Financial Summary:

For the six-month period ended June 30^th:

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

Financial Highlights:

Total revenue decreased 23%, year over year.

Cost of sales for the six-month period ended June 30^th, 2023 was $224,947 or 53% of revenue resulting in a gross margin of $201,140 or 47% of revenue. In comparison, the cost of sales for the same period in 2022 was $271,656 or 49% of revenue resulting in a gross margin of $280,786 or 51% 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 June 30^th, 2023 decreased to $147,304, from $167,139 for the same period in 2022, a 12% decrease. The decrease in selling expenses is a result of reduced commissions (22%), advertising (14%) and salaries (10%).

Administrative expenses for the six-month period ended June 30^th, 2023, increased to $1,010,144 from $734,081 for the same period in 2022, a 37% increase. The increase in administrative expenses is primarily attributed to increased spending on general and administrative expenses (71%) and advisory fees (73%). Stock based compensation expense increased 278% in 2022 due to an increase in stock options granted.

Net research and development expenses for the six-month period ended June 30^th, 2023, decreased to $1,619,839 from $2,338,855 for the same period in 2022, a 31% decrease.

Break Through Designation Update

In 2020, the FDA granted Theralase® Fast Track Designation ("FTD") for Study II. As a Fast Track designee, Theralase® has access to early and frequent communications with the FDA to discuss Theralase®'s development plans and ensure the timely collection of clinical data to support the approval process. The accelerated communication with the FDA potentially allows, the Study II Treatment, to be the first intravesical, patient-specific, light-activated, Ruthenium-based PDC for the treatment of patients diagnosed with BCG-Unresponsive NMIBC CIS, (with or without recurrent / resected papillary T_a/T₁ tumours). FTD can also lead to Break Through Designation ("BTD"), Accelerated Approval ("AA") and/or Priority Review, if certain criteria are met, which the FDA has previously defined to the Company for BTD as clinical data on approximately 20 to 25 patients enrolled and provided the primary Study II Treatment, who demonstrate significant safety and efficacy clinical outcomes.

In 2021, Theralase® completed its first significant milestone of Study II by enrolling and treating (primary Study Treatment) 25 patients.

In 2022, Theralase® completed its second significant milestone of Study II by enrolling and treating (primary Study Treatment) 50 patients.

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 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 late 3Q2023 / early 4Q2023 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 4Q2023.

Study II Preliminary Clinical Data:

To date, Study II has provided the primary study treatment for 60 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 33% achieved a CR and 38% 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 34% achieved a CR and 41% 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 59 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.
• Three 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 39 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=59) 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:

• 13 Evaluable Patients that 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 (13/39 = 33%).
• 36 Evaluable Patients that achieved CR on at least one assessment date and thus achieved the primary objective of Study II (36/57 = 63%)

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:

• Approximately 80% of patients remained in Study II after 90 days, following the initial Study II Treatment.
• 39% of Total Response patients have a duration of response ≥ 450 days.
• 28% of Complete Response patients have a duration of response ≥ 450 days.

Serious Adverse Events

For 60 patients treated in Study II, there have been 9 Serious Adverse Events ("SAEs") reported:

• 1 - Grade 1 (resolved within 1 day)
• 2 - Grade 2 (resolved within 1 and 1 days, respectively)
• 3 - Grade 3 (resolved within 5, 80 and 107 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.
