Recurring announcements also cover operating and financial results, non-brokered private placements, line-of-credit financing, capital-structure disclosure, governance matters and development collaborations. The company’s news commonly links research progress with funding needs, regulatory pathways, intellectual-property considerations and commercialization risks for its small-molecule drug formulations.
Theralase Technologies (TLTFF) announced it will present new preclinical research on radiation-activated Rutherrin® at the ASTRO 2025 67th Annual Meeting in San Francisco. The study evaluates Rutherrin®, a ruthenium-based drug formulated with human transferrin, against radiation alone in treating cancer.
The research explores Rutherrin's dual cancer-fighting mechanism: immediate cytotoxicity through Reactive Oxygen Species generation and sustained immune response through Immunogenic Cell Death. Key aspects to be presented include tumor targeting, blood-brain barrier penetration, survival rates, and resistance inhibition.
The company plans to complete GLP toxicology studies in 2025 and aims to launch clinical studies in early 2026 targeting multiple cancers including GBM, lung, pancreatic, lymphoma, and colorectal cancers.
Theralase Technologies (TLTFF) has announced groundbreaking preclinical results showing that their radiation-activated Rutherrin® treatment is 100 times more effective at destroying cancer cells compared to radiation therapy alone. The company will present these findings at the ASTRO 2025 conference in San Francisco.
Key findings demonstrate that Rutherrin®, a ruthenium-based small molecule drug, shows selective tumor targeting, enhanced blood-brain barrier penetration with 10x higher concentrations in GBM tumors, and combines direct tumor cell destruction with immune activation. The treatment works through Radio Dynamic Therapy (RDT), generating Reactive Oxygen Species for immediate cytotoxicity and Immunogenic Cell Death for durable immune response.
The company plans to complete GLP toxicology studies in 2025 and launch clinical studies in early 2026, targeting GBM, lung, pancreatic, lymphoma, and colorectal cancers.
Theralase Technologies (TLTFF) has announced a significant breakthrough in cancer treatment research. Their lead drug Ruvidar has been proven preclinically to effectively inhibit DeUbiquitinating Enzymes (DUBs), which are linked to various cancers and neurodegenerative diseases.
The research demonstrates that Ruvidar works through a dual mechanism: it inhibits DUBs activity in a dose-dependent manner and induces oxidative stress through Reactive Oxygen Species (ROS) production. At 100 μM concentration, Ruvidar nearly eliminates DUBs activity completely.
This discovery is particularly significant as DUBs are associated with drug resistance in cancer treatments. By targeting DUBs, Ruvidar could potentially be used in combination with various chemotherapy drugs and radiotherapy to combat chemoradiotherapy-resistant cancers.
Theralase Technologies (TSXV: TLT) (OTCQB: TLTFF) has successfully closed a non-brokered private placement, raising CAN $419,124 through the issuance of 1,995,829 units at CAN $0.21 per unit. Each unit includes one common share and one warrant, with warrants exercisable at CAN $0.32 per share for 5 years.
The proceeds will fund multiple initiatives including:
- Phase II Non-Muscle Invasive Bladder Cancer clinical study
- Herpes Simplex Virus treatment research
- Rutherrin® development for various solid-core tumours (brain, lung, pancreatic, muscle invasive bladder, and colorectal cancer)
- Working capital and corporate purposes
The company paid CAN $630 in broker's fees and issued 1,500 broker warrants. All securities are subject to a four-month hold period expiring August 15th, 2025.
Theralase Technologies (OTCQB: TLTFF) has announced breakthrough results for their drug Ruvidar in treating Herpes Simplex Virus Type 1 (HSV-1). In preclinical animal studies, Ruvidar (1%) demonstrated superior efficacy compared to FDA-approved treatments Acyclovir (5%) and Abreva (10% Docosanol).
Key findings show that Ruvidar completely healed HSV-1 lesions with just one daily application over 5 days, while competing treatments required 5 applications daily for 5-6 days and still failed to achieve complete healing. The drug's effectiveness is attributed to its positive charge, which enables it to block viral glycoproteins and prevent virus replication.
Following these successful results, Theralase will proceed with formulating Ruvidar into topical form, complete GLP toxicology studies, and initiate a Phase I/II adaptive clinical study to evaluate its safety and efficacy in human patients.
Theralase Technologies (TLTFF) has announced a significant breakthrough in treating BCG-Unresponsive Non-Muscle Invasive Bladder Cancer (NMIBC). A patient diagnosed with Carcinoma In-Situ (CIS) has maintained a Complete Response for over 7 years following a single treatment with their light-activated RuvidarTM therapy.
The treatment involved administering Theralase's lead molecule RuvidarTM, activated by the TLC-3200 medical laser system. CIS, found in about 10% of bladder cancer cases, is an aggressive form of NMIBC with high recurrence rates. The company plans to complete its Phase II NMIBC clinical study in 2025, followed by regulatory submissions to Health Canada and FDA in 2026.
The company is also exploring RuvidarTM's potential applications in treating various conditions, from herpes simplex virus lesions to aggressive cancers like glioblastoma multiforme, non-small cell lung cancer, pancreatic cancer, and Muscle Invasive Bladder Cancer.
Theralase Technologies (TSXV: TLT) (OTCQB: TLTFF) has announced promising results for their drug Ruvidar™ in treating Herpes Simplex Virus Type 1 (HSV-1). In preclinical animal trials, Ruvidar demonstrated superior efficacy compared to standard treatments Acyclovir and Abreva.
The global HSV treatment market, valued at $2.8 billion in 2024, is projected to reach $4.7 billion by 2033, with North America holding a 37.1% market share. An estimated 3.8 billion people globally have HSV-1, highlighting significant market potential.
The research showed Ruvidar's unique mechanism of action, utilizing positive charge to block viral glycoproteins and prevent virus replication. Following these successful preclinical results, Theralase plans to begin formulating Ruvidar into topical form and commence Phase I/II adaptive clinical studies in 2025, pending funding, to evaluate its safety and efficacy in treating cold sore lesions in humans.
