https://images.newsfilecorp.com/files/2786/299492_1988af03149dd9a6_001full.jpgFinancial Highlights:For the Quarter ended March 31st, 2026 (All funds in Canadian Dollars):Total revenue increased to $132,634 from $91,190 for the same period in 2025, a 45% increase.Cost of sales for the three-month period ended March 31st, 2026, was $68,250 (51% of revenue) resulting in a gross margin of $64,382 (49% of revenue). In comparison, the cost of sales for the same period in 2025 was $77,896 (85% of revenue) resulting in a gross margin of $13,294 (15% of revenue). Selling expenses decreased to $66,534 from $68,143 for the same period in 2025, a 2% decrease. The decrease in selling expenses is primarily a result of decreased spending on advertising (64%) and travel (38%).Administrative expenses for three-month period ended March 31st, 2026, decreased to $463,553 from $555,074 for the same period in 2025, a 16% decrease. The decrease in administrative expenses is primarily a result of decreased spending on insurance (20%) and professional fees (45%). Net research and development expenses for the three-month period ended March 31st, 2026, decreased to $564,724 from $877,670 for the same period in 2025, a 36% decrease. The decrease in research and development expenses is attributed to a decrease in costs for Study II patient enrollment and treatment, as the clinical study reaches completion. Research and development expenses represented 52% of the Company's operating expenses and represent investment into the research and development of the Company's Drug Division.The net loss for the three-month period ended March 31st, 2026, was $1,031,785, which included $172,118 of net non-cash expenses (i.e.: amortization, stock-based compensation expense). This compared to a net loss for the same period in 2025 of $1,471,250, which included $254,523 of net non-cash expenses. The Drug Division represented $803,352 (78%) of this loss. The decrease in net loss is primarily attributed to decreased spending on research and development expenses in Study II, as the clinical study reaches completion. Operational Highlights: Collaborative Clinical Development AgreementOn January 12th, 2026, the Company announced that it had entered into a collaborative clinical development agreement dated January 9th, 2026 with Ferring Pharmaceuticals, expanding the Company's existing Phase II NMIBC clinical program (NCT03945162) through the addition of a new cohort evaluating Ruvidar® (TLD-1433) in combination with Adstiladrin® (nadofaragene firadenovec-vncg) for adult patients diagnosed with high-risk Bacillus Calmette-Guérin ("BCG")-Unresponsive Non-Muscle Invasive Bladder Cancer ("NMIBC") Carcinoma In-Situ ("CIS") with or without papillary disease (±Ta/T1) ("Study II"). Under the terms of the agreement, the Company will remain the sponsor of the study, with both parties providing clinical oversight through a joint development committee. The new cohort is expected to be enrolled and treated initially in the United States and, subject to written agreement, may expand into Canada or other jurisdictions.Study II Interim Clinical DataCohort 1Theralase® has completed enrollment in Study II, with the Clinical Study Sites ("CSSs") enrolling and providing the primary Study Procedure to 92 patients. Additional patients may be enrolled, until all CSSs have been closed to enrollment.According to the clinical study design, a patient is considered to have completed Study II, if they received the Study Procedure and have been assessed by the Principal Investigator ("PI") for up to 15 months or they have been prematurely removed from the clinical study by the PI for failure to respond or failure to comply with the clinical study design. According to this definition, 82 patients have completed Study II (with 10 patients on study pending clinical data), resulting in the following interim clinical data in support of the Study II endpoints:A total of 92 patients have been enrolled and treated in the study. Of these patients, 81% were ≥ 65 years of age, 81% male and 83% white. Tumour stage was distributed as follows: pure 81% CIS; 12% CIS + T1; and 7% CIS + Ta. 98% were classified as BCG-Unresponsive with 2% BCG-Intolerant. The median number of BCG instillations was 15.5.As of May 29th, 2026, 89 patients have been assessed for response outcomes, evaluable for the primary endpoint analysis.Primary Endpoint Performance (Complete Response at any Point in Time)The primary endpoint of Study II is the achievement of Complete Response ("CR") at any point in time following administration of the Study Procedure. Interim analysis demonstrates that 65.2% (58 out of 89) evaluable patients achieved CR.Primary Endpoint Performance (CR at any Point in Time)

Among patients evaluable for durability of response, 40.4% (21 of 52 evaluable patients) maintained a CR at 450 days.Secondary Endpoint Performance (Duration of CR) (450 Days)

Theralase® and the independent Data Safety Monitoring Board believes all SAEs reported to date are unrelated or unlikely related to the Study Drug or Study Device.The tertiary endpoint assesses the safety profile of the Study Procedure.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. Treatment Emergent Adverse Events ("TEAEs") were noted, but did not meet the SAE criteria. TEAEs included urinary frequency (65%), hematuria (62.5%) and urinary urgency (53.8%), which resolved within 1 month of treatment. There have been 24 SAEs reported: 1 x Grade I, 3 x Grade II, 13 x Grade III, 5 x Grade IV (all resolved between 1 to 82 days) and 2 x Grade V (Unlikely Related to the Study Drug, Study Device or Study Procedure). A high majority of SAEs were not treatment related and none were directly related to the Study Drug or Study Device.Tertiary Endpoint Performance (Safety) (450 Days)

Additional clinical data may influence or alter current response trends. Regulatory Pathway, Commercialization Strategy and FDA GuidanceIf approved by Health Canada and the FDA, the clinical data collected from Study II represents a transformative therapeutic option for patients diagnosed with BCG-Unresponsive NMIBC CIS, who would otherwise face radical cystectomy (surgical removal of the bladder). The Theralase® procedure has demonstrated a robust CR and sustained durability of that response, with the majority of patients receiving only a single procedure.Following the completion of patient follow-up and final clinical data analysis, Theralase® intends to submit a New Drug Application ("NDA") to Health Canada and the United States Food and Drug Administration ("FDA") in 3Q2026, under a rolling review, with regulatory decisions anticipated in 1H2027.Cohort 2Theralase®, in conjunction with Ferring Pharmaceutical, subject to FDA approval, is preparing to launch a combinational clinical study to investigate the safety and efficacy of combining light-activated Ruvidar® with Adstiladrin.It is anticipated that the complementary mechanisms of action (Ruvidar® targets bladder cancer cells directly, Adstiladrin® targets health bladder cells to produce Interferon to stimulate the innate and adaptive immune system) will provide a strong additive effect in the treatment of patients being treated for BCG-Unresponsive NMIBC CIS.In the procedure, patients will be treated with Ruvidar® (1 hour of drug instillation, approximately 1 hour of light activation), then at another visit, they will be treated with Adstiladrin® (1 hour procedure), both in outpatient procedures. Under the clinical protocol, the patient may receive up to 4 treatments of Adstiladrin®.The presiding uro-oncologist will have the option to deliver an additional re-induction Study Procedure, if the patient recurs.The patient will be followed for 15 months after initial Study Procedure and up to 3 years for post-study follow-up.Commercialization and Strategic PartnershipsIn parallel with the finalization of Study II, Theralase® is actively pursuing commercialization opportunities and strategic partnerships to support the global marketing and distribution of Ruvidar®. The Company is interested in engaging in discussions with pharmaceutical companies across multiple geographic regions regarding:Licensing arrangements for Ruvidar® in the treatment of BCG-Unresponsive NMIBC CIS in various geographic territoriesCollaborative clinical research initiatives focused on the application of light-activated Ruvidar® for broader NMIBC indicationsCollaborative clinical research combining Ruvidar®, with other FDA-approved drugs to enhance treatment efficacyAbout Study II:
Study II utilizes the therapeutic dose of the patented drug, Ruvidar® (TLD-1433) activated by the patented study device, the TLC-3200 Medical Laser System. Study II has enrolled and treated 92 BCG-Unresponsive NMIBC CIS patients in 11 clinical study sites located in Canada and the United States. About Theralase® Technologies Inc.:

https://images.newsfilecorp.com/files/2786/295879_0ea03f92e40a1b12_001full.jpgFinancial Highlights:For the year ended December 31st, 2025 (All funds in Canadian Dollars):Total revenue decreased to $816,468 from $1,033,431 for the same period in 2024, a 21% decrease.Cost of sales for the year ended December 31, 2025, was $309,337 (38% of revenue) resulting in a gross margin of $507,131 (62% of revenue). In comparison, the cost of sales for the same period in 2024 was $479,405 (46% of revenue) resulting in a gross margin of $554,026 (54% of revenue). Selling expenses decreased to $287,012 from $354,636 for the same period in 2024, a 19% decrease. The decrease in selling expenses is primarily a result of decreased spending on salaries (17%) and commissions (38%).Administrative expenses for year ended December 31, 2025, increased to $1,943,014 from $1,734,065 for the same period in 2024, a 12% increase. The increase in administrative expenses is primarily a result of increased spending on general and administrative expenses (17%) and professional fees (70%). Net research and development expenses for the year ended December 31, 2025, decreased to $2,452,445 from $2,753,674 for the same period in 2024, a 9% decrease. The decrease in research and development expenses is attributed to a decrease in costs for Study II patient enrollment and treatment. Research and development expenses represented 53% of the Company's operating expenses and represent investment into the research and development of the Company's Drug Division.The net loss for the year ended December 31, 2025, was $4,120,817, which included $840,227 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 2024 of $4,256,114, which included $793,181 of net non-cash expenses. The Drug Division represented $3,400,303 (83%) of this loss. The decrease in net loss is primarily attributed to decreased spending on research and development expenses in Study II. Operational Highlights: Collaborative Clinical Development AgreementOn January 12, 2026, the Company announced that it had entered into a collaborative clinical development agreement dated January 9, 2026 with Ferring Pharmaceuticals, expanding the Company's existing Phase II NMIBC clinical program (NCT03945162) through the addition of a new cohort evaluating Ruvidar® (TLD-1433) in combination with Adstiladrin® (nadofaragene firadenovec-vncg) for adult patients diagnosed with high-risk Bacillus Calmette-Guérin ("BCG")-Unresponsive Non-Muscle Invasive Bladder Cancer ("NMIBC") Carcinoma In-Situ ("CIS") with or without papillary disease (±Ta/T1) ("Study II"). Under the terms of the agreement, the Company will remain the sponsor of the study, with both parties providing clinical oversight through a joint development committee. The new cohort is expected to be enrolled and treated initially in the United States and, subject to written agreement, may expand into Canada or other jurisdictions.Study II Interim Clinical DataCohort 1
Theralase® has successfully completed its targeted enrollment for Study II, exceeding expectations with 91 patients treated by Clinical Study Sites ("CSSs") and may continue to enroll additional patients as remaining sites finalize and close to enrollment.According to the clinical study design, a patient is considered to have completed Study II, if they received the Study Procedure and have been assessed by the Principal Investigator ("PI") for up to 15 months or upon earlier withdrawal by the PI due to non-response or non-compliance.Based on this definition, 82 patients have completed Study II, while 9 remain active with pending clinical data. Interim results supporting the Study II endpoints are summarized below.A total of 91 patients have been enrolled and treated. The cohort was predominantly ≥65 years of age (81%), male (81%), and white (83%). Tumour staging was distributed as follows: 81% carcinoma in situ ("CIS") only, 12% CIS + T1, and 7% CIS + Ta. In addition, 98% of patients were classified as BCG-unresponsive and 2% as BCG-intolerant. The median number of prior BCG instillations was 15.5.As of April 30, 2026, 89 patients have been assessed for response outcomes and are evaluable for the primary endpoint analysis.Primary Endpoint Performance (Complete Response at any Point in Time)
The primary endpoint of Study II is the achievement of Complete Response ("CR") at any point in time following administration of the Study Procedure. Interim analysis demonstrates that 65.2% (58 out of 89) evaluable patients achieved CR.Primary Endpoint Performance (CR at any Point in Time)

The secondary endpoint evaluates the sustainability of CR at 12 months, after initial CR determination (450 days post-treatment). Among patients evaluable for durability of response, 40.4% (21 of 52 evaluable patients) maintained a CR at 450 days.Secondary Endpoint Performance (Duration of CR) (450 Days)

The tertiary endpoint is defined as patients who are diagnosed with a Serious Adverse Event ("SAE") ≥ 4 directly caused by the Study Drug or Study Device, which did not resolve within 450 days.Theralase® and the independent Data Safety Monitoring Board believe all SAEs reported to date are unrelated or unlikely related to the Study Drug or Study Device.The tertiary endpoint assesses the safety profile of the Study Procedure.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. Treatment Emergent Adverse Events ("TEAEs") were noted, but did not meet the SAE criteria. TEAEs included urinary frequency (65%), hematuria (62.5%) and urinary urgency (53.8%), which resolved within 1 month of treatment. There have been 24 SAEs reported: 1 x Grade I, 3 x Grade II, 13 x Grade III, 5 x Grade IV (all resolved between 1 to 82 days) and 2 x Grade V. A high majority of SAEs were not treatment related and none were directly related to the Study Drug or Study Device.Tertiary Endpoint Performance (Safety) (450 Days)

https://images.newsfilecorp.com/files/2786/295879_figure2.jpgNote: These clinical results are interim in nature. Study II remains ongoing. Additional clinical data may influence or alter current response trends.  Regulatory Pathway, Commercialization Strategy and FDA Guidance
If approved by Health Canada and the FDA, the clinical data collected from Study II represents a transformative therapeutic option for patients diagnosed with BCG-Unresponsive NMIBC CIS, who would otherwise face radical cystectomy (surgical removal of the bladder). The Theralase® Study Procedure has demonstrated a robust CR and sustained durability of that response, with the majority of patients receiving only a single Study Procedure.Following the completion of patient follow-up and final clinical data analysis, Theralase® intends to submit a New Drug Submission ("NDS") to Health Canada and a New Drug Application ("NDA") to the United States Food and Drug Administration ("FDA") in 3Q2026, under a rolling review, with regulatory decisions anticipated in 1H2027.Cohort 2
Theralase®, in conjunction with Ferring Pharmaceutical, subject to FDA approval, is preparing to launch a combinational clinical study to investigate the safety and efficacy of combining light-activated Ruvidar® with Adstiladrin.It is anticipated that the complementary mechanisms of action (Ruvidar® targets bladder cancer cells directly, while Adstiladrin® targets health bladder cells to produce Interferon to stimulate the innate and adaptive immune system) will provide an additive effect in the treatment of patients being treated for BCG-Unresponsive NMIBC CIS.In the Study Procedure, patients will be treated with Ruvidar® (1 hour of drug instillation, 1 hour of light activation), then at another visit, they will be instilled with Adstiladrin® (1 hour procedure), both in outpatient procedures. Under the clinical protocol, the patient may receive up to 4 treatments of Adstiladrin®.The presiding uro-oncologist will have the option to deliver an additional re-induction Study Procedure, if the patient recurs.The patient will be followed for 15 months after initial Study Procedure and up to 3 years for post-study follow-up.Commercialization and Strategic Partnerships
In parallel with the finalization of Study II, Theralase® is actively pursuing commercialization opportunities and strategic partnerships to support the global marketing and distribution of Ruvidar®. The Company is pursuing discussions with pharmaceutical companies across multiple geographic regions regarding:Licensing arrangements for Ruvidar® in the treatment of BCG-Unresponsive NMIBC CIS in various geographic territoriesCollaborative clinical research initiatives focused on the application of light-activated Ruvidar® for broader NMIBC indicationsCollaborative clinical research combining Ruvidar®, with other FDA-approved drugs to enhance treatment efficacyAbout Study II:
Study II utilizes the therapeutic dose of the patented drug, Ruvidar® (TLD-1433) activated by the patented study device, the TLC-3200 Medical Laser System. Study II has enrolled and treated 91 BCG-Unresponsive NMIBC CIS patients in 11 clinical study sites located in Canada and the United States. About Theralase® Technologies Inc.:

Original: Theralase(R) Closes $1.1 M Non-Brokered Private Placement

Theralase(R) Demonstrates That X-Ray-Activated Rutherrin(R) Is Significantly More Effective than Radiation Alone in the Destruction of Muscle Invasive Bladder CancerMarch 9, 2026 7:00 AM
NewsfileToronto, Ontario--(Newsfile Corp. - March 9, 2026) - Theralase® Technologies Inc. (TSXV: TLT) (OTCQB: TLTFF) ("Theralase®" or the "Company"), a clinical stage pharmaceutical company dedicated to the research and development of energy-activated small molecules for the safe and effective destruction of cancer, bacteria and viruses, is pleased to present its latest preclinical data demonstrating that X-Ray-activated Rutherrin® is effective in the destruction of Muscle Invasive Bladder Cancer ("MIBC").In the MIBC preclinical models conducted by the Theralase® research team, Rutherrin® demonstrated an ability to significantly enhance the efficacy of radiation therapy in the destruction of MIBC, supporting its potential as an effective drug for this devastating condition.Approximately 25% of the 83,000+ new bladder cancer cases diagnosed annually in the United States and 13,300+ cases in Canada are MIBC. MIBC carries a significant risk of death that has not changed in decades.1,2The standard of care for MIBC is currently cisplatin-based neoadjuvant chemotherapy (pre-operative) followed by Radical Cystectomy ("RC") (bladder removal).1 In patients who undergo RC, systemic recurrence rates vary by stage, ranging from 20% to 70%.3 As a bladder-preservation option, Tri Modal Therapy ("TMT"), comprised of maximal trans-urethral resection of the bladder tumour, followed by radiation and chemotherapy, has become increasingly popular in recent years; however, patients must be appropriately selected.4,5Based on the latest preclinical data, Theralase® is planning to conduct a Phase 0/I/II adaptive clinical study with radiation-activated Rutherrin®, with or without chemotherapy and/or immunotherapy, subject to regulatory approval, for patients diagnosed with MIBC to provide an alternative treatment option versus RC or TMT.In vitro experiments using mouse MIBC cells ("MBT-2"), Rutherrin® combined with 2.5 Gray X-Ray radiation resulted in significantly greater cell death compared to radiation alone (Figure 1). These results indicate that Rutherrin® enhances radiation-induced cytotoxicity, supporting its potential as a radiosensitizer in the destruction of MIBC.Figure 1: In Vitro MBT-2 Cell Kill After Rutherrin® and 2.5 Gray X-Ray TreatmentTo view an enhanced version of this graphic, please visit:
https://images.newsfilecorp.com/files/2786/286595_17f6f13c641d1bf2_001full.jpgMBT-2 cells were used to establish an orthotopic MIBC model in mice, by surgically injecting the cells directly into the muscle layer of the mouse's bladder, leading to tumour growth and invasion of the muscle layer. In this model, the tumour grew into the bladder lumen, pushing against the inner urothelial layer, resulting in a reduction of the volume available for urine storage (Figure 2). If left untreated, the tumour would continue to grow until the bladder was completely blocked, rendering it inoperable and reaching the humane endpoint.Figure 2: Histological Analysis Confirmed Successful Establishment of a MIBC ModelTo view an enhanced version of this graphic, please visit:
https://images.newsfilecorp.com/files/2786/286595_17f6f13c641d1bf2_002full.jpgAfter systemic Rutherrin® was administered intravenously to mice with MBT-2 tumours, tissue analysis showed that tumour sites had approximately four times higher Rutherrin® levels than normal bladder, demonstrating tumour-selective uptake and a favourable therapeutic index (drug in cancer cells versus healthy cells).

https://images.newsfilecorp.com/files/2786/286595_17f6f13c641d1bf2_003full.jpgIn further research, Theralase® is conducting an ongoing in-vivo MIBC study assessing the use of repeatable, intravenous Rutherrin® administration, in combination with fractionated radiation therapy (total cumulative dose of 25 Gray). At day 35 in this study, all mice in the Rutherrin® + radiation group survived and showed complete tumour clearance; however, in the radiation alone group mice exhibited persistent and larger tumour volumes, with 50% of the mice reaching their humane endpoint post treatment, with the other 50% displaying steady growth in their tumours. (Figure 4 and 5). These results indicate that Rutherrin® significantly enhanced radiation efficacy and may improve tumour control even when lower doses of radiation are employed.Figure 4: Tumour Volume Analysis in MBT-2 Mouse Model Treated with 25 Gray Cumulative RadiationTo view an enhanced version of this graphic, please visit:

https://images.newsfilecorp.com/files/2786/286595_17f6f13c641d1bf2_005full.jpgMark Roufaiel, PhD, Research Scientist at Theralase®, commented, "These preclinical findings demonstrate that Rutherrin® selectively accumulates in MIBC tumours versus health bladder tissue and significantly enhanced the therapeutic effect of radiation. Most importantly, we observed complete tumour clearance in X-Ray-activated Rutherrin® treated animals even under low radiation dosing conditions. This supports the potential of Rutherrin® to improve radiation response and expand treatment options for patients with aggressive MIBC."Arkady Mandel, MD, PhD, DSc, Chief Scientific Officer, Theralase®, stated, "Treatment options for MIBC patients are limited to cisplatin-based chemotherapy before RC or TMT. Preclinical data collected supports the clinical opportunity of employing X-Ray-Activated Rutherrin® in the treatment of difficult-to-treat cancers; such as, glioblastoma multiforme, non-small cell lung cancer, as previously reported, and now based on the recent data, MIBC. In preclinical studies, mice treated with radiation alone did not survive or continued to show detectable cancer with rapid tumour progression; whereas, mice treated with a combination of Rutherrin® and radiation therapy showed no detectable cancer. These results will hopefully lay the groundwork for new therapeutic approaches for patients faced with these challenging diseases."Roger DuMoulin-White, BSc, P.Eng, Pro.Dir, President, Chief Executive Officer and Chairman of the Board of Theralase®, added, "The combination of selective tumour uptake by Rutherrin®, demonstrated X-Ray enhancement in vitro, accelerated tumour regression and complete tumour destruction in vivo at low radiation doses collectively supports the executive decision by Theralase® to pursue clinical development of Rutherrin®, as a radiation sensitizer in patients diagnosed with GBM, NSCLC and MIBC, subject to regulatory approval."References:

The data supports the use of light-activated Ruvidar® in the treatment of patients with high-grade, high-risk NMIBC. In addition, the latest results demonstrate a long-lasting duration of complete response induced by this innovative technology, which is able to be completed within a few hours and is suitable for patients with CIS of the urinary bladder, who have not responded to previous therapies and who are currently facing a life-altering option, such as radical cystectomy."Roger DuMoulin-White, BSc, P.Eng, Pro.Dir, President and Chief Executive Officer, Theralase® stated, "The acceptance of the Theralase® abstract for presentation at the EAU26 Annual Conference is a testament to the importance and significant impact that this clinical research could have on the lives of bladder cancer patients. We look forward to the presentation and the continued development of Ruvidar® for bladder cancer patients. With patient enrollment completed, clinical data is expected to be submitted to Health Canada and the FDA in a rolling review commencing 3Q2026. Pending successful regulatory approval, expected in 2027, Theralase® plans to make this technology commercially available to the entire urological community, commencing with Canada and the United States."About EAU26:
EAU26 is Europe's largest urological event, with researchers and scientists from around the world presenting their latest research, which is critically examined and discussed by the field's leading experts. The EAU represents the leading authority within Europe on urological practice, research and education, with over 19,000 medical professionals.About Study II:
Study II utilizes the therapeutic dose of the patented drug, Ruvidar® (TLD-1433) activated by the patented study device, the TLC-3200 Medical Laser System. Study II has enrolled and treated 90 BCG-Unresponsive NMIBC CIS patients in 12 clinical study sites located in Canada and the United States. About NMIBC:
NMIBC is a form of bladder cancer that is found in the inner layer cells of the bladder and does not invade into or beyond the muscle wall.2 In the United States, bladder cancer is the sixth most common cancer,3 fourth among men4 and it is estimated that there will be approximately 84,870 new cases of bladder cancer in the U.S. in 2025.4 Historically, 75% of bladder cancer presents as NMIBC.5 In patients with high-risk NMIBC, intravesical BCG remains the first-line standard-of-care; however, approximately one third of patients with NMIBC will not respond to BCG therapy and 50% of those with an initial response will experience recurrence or progression of their disease.6 Current treatment options for BCG-unresponsive patients are very limited and National Comprehensive Cancer Network guidelines recommend cystectomy (complete removal of the bladder).7About Ruvidar®:

Patient Population: Bacillus Calmette-Guérin ("BCG")-Unresponsive Non-Muscle Invasive Bladder Cancer ("NMIBC") Carcinoma In-Situ ("CIS"), who have failed standard-of-care therapy and are facing radical cystectomy (bladder removal) ("Study II").About NMIBC:NMIBC is a form of bladder cancer that is found in the inner layer cells of the bladder and does not invade into or beyond the muscle wall.2 In the United States, bladder cancer is the sixth most common cancer,3 fourth among men,4 and it is estimated that there will be approximately 84,870 new cases of bladder cancer in the U.S. in 2025.4 Historically, 75% of bladder cancer presents as NMIBC.5 In patients with high-risk NMIBC, intravesical BCG remains the first-line standard-of-care; however, approximately one third of patients with NMIBC will not respond to BCG therapy and 50% of those with an initial response will experience recurrence or progression of their disease.6 Current treatment options for BCG-unresponsive patients are very limited and National Comprehensive Cancer Network guidelines recommend cystectomy (partial or complete removal of the bladder).7About Ruvidar®:Ruvidar® is a small molecule activated by energy, intended for the safe and effective destruction of cancer, bacteria and viruses.About Theralase® Technologies Inc.:Theralase® is a clinical stage pharmaceutical company dedicated to the research and development of energy-activated small molecules for the safe and effective destruction of cancer, bacteria and viruses.Additional information is available at www.theralase.com and www.sedarplus.ca.References:Rose KM et al., Systematic Review and Meta-Analysis of Response Rates in BCG-unresponsive Non-Muscle-Invasive Bladder Cancer: A Consensus Statement From the International Bladder Cancer Group.

Original: Theralase(R) Provides Update on Bladder Cancer Clinical Study

test

Does not look like a real update on Ruvidar and bladder cancer till Summer 2026, earliest.  Everything else late 2026 early 2027....so I don't think we see much action till results come out - probably going to be a good opportunity to accumulate at a good discount over next several months. 

Theralase... are you breathing?

...zzzzzzz.. what a snooze factory..

I think we see something big by end of next month. Cannot believe the potential of this company yet the price is stagnant. Not a fan of the CEO and that might be hurting us.

They have had large placements that have been horrible to investors. Roger seems to have zero traction with obtaining funding and that could be the result of terrible relationships with tutes and past investors. I have no idea why he has come back to the helm. Not a wise choice but nothing you can do about it. They have no IR at present as the current one is a BOD member and personal friend of Roger. Obviously works cheap. Roger's wife is second in command at the company so it is all kept in house.Some of usshareholders are concerned they are going to run out of capital because they can only raise in paltry amounts and that is going to dry up.

Great product but is hindered by management that cannot raise money. At present they are still trying to tap a large investor(public news) to take down a chunk but still no bite. I have no idea what will move the stock anymore. Every bit of news put out is meant by manipulative selling on the Venture Exchange. I really like the inventor of the drug. She is a wonderful lady.

TLTFF needs coverage, News, something to entice investors, way to quiet

Caveat Emptor, nice news but the management is outta its league.

Great PR today from Canada. Wish the stock had more volume but the potential for a big move is there. We just have to get rid of the management team and bring in someone capable of raising funds. The stock price is very cheap.

Had warrants that expired Aug 2024 sold them . Bought shares of BIG.v . Big has found a very large ore deposit in Idaho . Profound science at TLT . Big pharma is corrupt .

Big should show $10 in 24 and multiples in 05 as they show how valuable it is .

“Cure for Cancer?”
Sounds good to Me.

Chart reader says a technical buy to .39 . We are so close to a boil over . Good luck !

Chart reader says a technical buy to .39 . We are so close to a boil over . Good luck !

Some wording in patent gets us a temporary rejection . How the rest of it will roll out is beyond me at this time .

This is well said . https://stockhouse.com/companies/bullboard/v.tlt/theralase-technologies-inc?threadid=35321535

This is a treatment that kills cancer at the cellular level . If the first or 7th treatment doesn't get what is left , treat them again . No side effects ????

That 89% is for efficacy .

If we take out the wrong dose patients this poster says 89% .

Post by Guzzi , TLT.v looks like the big time .

Thanks.. maybe the stock will pop..

after the next announcing of clinical results.. FEB 16-18 San Fran..

https://finance.yahoo.com/news/theralase-phase-ii-nmibc-clinical-120000686.html

Nice !

So far so good.. Theralase

In my thoughts as a small time stock watcher without any real insights into a company ..all I can really do is watch for sentiment in a stock chart then make some guesses.

Here is my latest guess on Theralase

Downward trend line broken = anticipation?

I don't know but I do see sustained volume along with the trend.. and the Warrant extension (again) has me thinking that Theralase wants long term warrant holders to get paid. Seems logical and fair since timelines are difficult to predict when it comes to live human testing.

I am taking all of this as a positive in advance of.. wait for it....news. Just like every other stock I dabble in.

Good summary of what TLTFF has . https://stockhouse.com/companies/bullboard?symbol=v.tlt&postid=35183957

Insiders have loaded up . Time for news to show why and price to be proof .

https://stockhouse.com/companies/bullboard/v.tlt/theralase-technologies-inc?postid=35015853

Great post from Stockhouse .

All of this action looks to set 2023 as the year for Theralase

Good timing for Theralase re:Biden

I like the moonshot analogy.. are we closer to the moon than we appear?

Someone thinks Theralace arrived.

Truth be told I don't have any facts except noting that the volume moving up over the last month has buoyed my spirit.

If cheap share were to be had they are going fast...er

This poster thinks we are almost at the point of proof .

https://stockhouse.com/companies/bullboard?symbol=v.tlt&postid=34954321

This stockhouse poster has a + view and the #s on TLT.

https://stockhouse.com/companies/bullboard?symbol=v.tlt&postid=34940829

Looks a bit like TLT ?????????? https://stockhouse.com/companies/bullboard?symbol=v.tlt&postid=34939963

The downside risk is very low . The upside could be high

Quarterly Update..

Seemes like positive growth despite
losing money.. that's expected.. isn't it?

Anyone read " Jessie Stine's " book ?

Egon. post at 4126 answers those ? of a long term investment .

https://investorshub.advfn.com/boards/read_msg.aspx?message_id=168672114

The board needs the opinion of a knowing trader . How can you place a value on this if it kills all cancers . How will it play out if it does .

Most likely play if it doesn't . How can you get a fair price for it ?

94.4 % kill of cancer out of 38 treated . Have to keep the mess ups in the data to keep the confusion . This poster figures it out .
