Study description: The objectives of this study are to evaluate the safety and potential efficacy (defined as decrease in tumor size) of a single injection of tigilanol tiglate (35%V/V), for equine sarcoid tumors.
Inclusion criteria:
- Horses must have suspected or confirmed, measurable, well-defined, nodular or fibroblastic sarcoid tumors
- Tumor volume must be 0.3 cm3 – 6 cm3.
- Horses must be otherwise healthy without concurrent disease, especially ongoing conditions (e.g. gastric ulceration) where the use of NSAIDs is contra-indicated.
- Prior treatment is acceptable but must be discontinued 8 weeks prior to enrollment.
- Owners must sign a consent form.
Horses will undergo preliminary staging tests including initial consultation and physical examination. Once deemed eligible for inclusion, the intent will be to inject one dose of tigilanol tiglate (35%V/V) into the tumor(s). At several time points following treatment (for up to 2 years), owners will be asked to submit photos of the tumor to UGA for assessment of treatment response. In some instances, the horse may be required to return to UGA for re-evaluation.
Tigilanol tiglate (35%V/V) will be provided at no cost as part of this trial. Costs of study related office visits, lab work, and ancillary medications such as NSAIDs and sedatives will also be covered by the Sponsor.
Duration of study: The study is currently OPEN. Duration of the study is until progression in tumor size, or a total of 24 months.
Potential benefits to veterinary medicine: Successful demonstration of efficacy and safety of this treatment may lead to large scale clinical trials and may provide a valuable option for veterinarians and horse owners seeking an alternative to surgical removal of sarcoid tumors.
