TFA-01 DEVELOPMENT TIMELINE

Development milestones

Entries appear in reverse chronological order and identify the date type, development workstream, progress and supporting evidence. Each entry distinguishes completed work, initiated projects and public disclosures.

12 verifiable milestones

Timeline dates may mark a contract or project start, a signed report, a formal filing or a public disclosure. The end of a project period, commissioning a study and initiating a study are distinct from study completion.

View the five development workstreams
  1. Interim R&D update

    02 · CMC / 04 · Canine OA research

    Nanoformulation development and preliminary cell testing advance

    TFA is advancing nanoformulation research to improve the dispersion of Antcin A in water and support injectable formulation development. Preliminary cell-based testing through a third-party research organization is also underway to prepare for a subsequent standardized canine osteoarthritis study.

    View evidence limitations

    This is an interim progress update as of September 10, 2026, not completion of a final formulation or a canine clinical study. Aqueous solubility, particle size and stability still require verification. Cell-based findings do not establish effectiveness in dogs.

  2. First-stage agreement signed

    04 · Canine OA clinical development

    TFA-01 first-stage canine osteoarthritis research agreement signed

    The first-stage canine osteoarthritis research agreement with Shanghai Pet-Sci was signed on August 11, 2026, supporting study design, documentation, assessment and reporting preparations.

    View evidence limitations

    The date records contract execution, not the start of dosing, study completion or regulatory approval. Subsequent study records will substantiate progress and findings.

  3. REPORT COMPLETED

    03 · Safety & toxicology

    14-day preliminary rat toxicology report completed

    The final report for a preliminary 14-day repeat-dose study in 24 female rats has been signed. It can inform dose selection and the design of subsequent formal studies.

    View evidence limitations

    This TF-15 study was not GLP regulatory toxicology or a long-term safety study. It does not establish safety in dogs, for purified Antcin A or for a final product.

  4. FILED

    01 · Molecule, mechanism & rights

    Antcin A platform cooperation framework publicly filed

    The company disclosed the cooperation and licensing framework for TFA-01 and the Antcin A platform on Form 6-K, providing a public record of the platform rights.

    View evidence limitations

    A cooperation and licensing framework does not establish drug approval, efficacy, safety or commercial outcomes.

  5. AGREEMENT SIGNED · RESEARCH ONGOING

    03 · Safety & toxicology / 02 · CMC

    Safety, toxicology, residue and formulation research program started

    The commissioned-research agreement identifies this date as the start of the project period for TFA-01 target-animal safety, toxicology, residue and nanoformulation research, conducted by the Graduate Institute of Animal Vaccine Technology.

    View evidence limitations

    This is the start of the project period specified in the agreement, not evidence that every study began on that date or has been completed. Safety, toxicology, residue and formulation-standardization work remains underway; the completed report and regulatory conclusions are still pending.

  6. STUDY STARTED

    03 · Safety & toxicology

    Dosing began in the 14-day preliminary rat safety study

    Repeat dosing began under the approved study plan to collect preliminary safety observations and inform later formal study design.

    View evidence limitations

    Study initiation is not study completion. This preliminary design cannot be extrapolated to canine or long-term safety.

  7. PUBLIC REPORT

    02 · CMC & controlled supply

    Early production and pharmacokinetic progress publicly disclosed

    Economic Daily reported on this date that the company had completed early production-related documentation and canine pharmacokinetic work in reference to Taiwan veterinary-drug registration data requirements, and had notified the Ministry of Agriculture of the progress as part of assembling a complete application package.

    View evidence limitations

    December 12, 2025 is the public-report date, not a statutory completion or agency-review date. At this stage the Ministry was informed of progress but had not formally reviewed or accepted these materials; formal review occurs only after the complete application package is submitted. The headline’s “phase one” is not a human Phase I trial.

  8. PATENT GRANTED

    02 · CMC & controlled supply

    U.S. cultivation-method and porous-carrier patent granted

    U.S. Patent No. 12,471,542 B2 was granted, covering an Antrodia cinnamomea cultivation method and a porous carrier used for cultivation.

    View evidence limitations

    The patent protects cultivation and carrier technology; it does not establish TFA-01 efficacy, safety or drug approval.

  9. STUDY COMPLETION DOCUMENTED

    01 · Molecule, mechanism & rights

    First industry-academia mechanism study completed

    The Chung Hwa University of Medical Technology final report records study completion on this date. The project conducted preliminary experiments to evaluate mechanisms suggested by published research and summarized Antrodia cinnamomea sample analyses, anti-inflammatory findings, steroid-combination experiments and cancer-cell-model results.

    View evidence limitations

    The report itself characterizes the work as preliminary and calls for batch reproducibility and further study. It does not establish direct receptor binding, formal synergy, a steroid-sparing effect, canine or human clinical efficacy, or drug approval.

  10. PLAN ANNOUNCED

    05 · Regulatory & commercialization

    Veterinary drug application initiative publicly announced

    A historical company release announced plans to advance Antcin A-based veterinary drug applications in Taiwan and China, creating a public starting point for later regulatory-data integration.

    View evidence limitations

    This was a forward-looking plan. It does not mean an application was submitted or accepted, required studies were completed, or a drug was approved.

    View the original release
  11. PUBLIC DISCLOSURE

    01 · Molecule, mechanism & rights

    Preliminary Antcin A and steroid combination work publicly released

    The company published preliminary combination findings presented at a February 22, 2025 research event. The release made publicly available early experimental observations on mechanisms suggested by published research.

    View evidence limitations

    The public material describes preliminary cell work and does not independently establish synergy, a steroid-sparing effect, direct receptor mechanism or clinical efficacy.

    View the original release
  12. INDUSTRY-ACADEMIA PROJECT PERIOD START

    01 · Molecule, mechanism & rights

    Project to evaluate mechanisms suggested by published research

    The written agreement specifies January 1, 2025 as the start of the collaboration period. Experimental work and the university’s contract administration did not fully align, so this date marks the contractual project period only. Study completion is documented in the June 5, 2025 final report.

    View evidence limitations

    This milestone marks the company’s first self-directed drug-related industry-academia project entering its formal project period. It does not mean the mechanism was fully proven, direct receptor binding was established, canine or human clinical efficacy was confirmed, or a drug was approved.
