Medicus Pharma Ltd. Announces Minor Use (MUMS) Designation from the FDA for Doxorubicin-Containing Microneedle Array (D-MNA) Patch

Company to Submit Product Development Plan to Treat External Squamous Cell Carcinoma (SCC) in Horses

Toronto, Ontario and Philadelphia, Pennsylvania - Newsfile Corp. - December 12, 2024 - Medicus Pharma Ltd. (NASDAQ: MDCX) (TSXV: MDCX) ("Medicus" or the "Company") is pleased to announce that its Investigational New Animal Drug (INAD File No.013880) has received Minor Use in Major Species Designation ("MUMS") from the U.S. Food and Drug Administration ("FDA") for its dissolvable Doxorubin-containing microneedle array (D-MNA) to treat external squamous cell carcinoma (SCC) in horses. The company received a notification from the FDA on December 9^th 2024. MUMS is a status similar to Orphan Drug status for human drugs. It entitles the company to an extended 7-year period of exclusive marketing following approval or conditional approval, provided that the company meets all requirements for maintaining the designation. "In a relatively short period of time, we have made remarkable progress with the FDA in advancing the clinical development program of the veterinary application of our novel D-MNA patch in treating SCC in horses," stated Dr. Raza Bokhari, Executive Chairman & CEO. "Developing a non-invasive treatment for equine SCC represents an untapped market opportunity that we are excited to pursue. The MUMS designation is an important catalyst to provide us a first mover advantage and also position us to possibly have a commercially viable product as early as 2026." Doxorubicin-containing microneedle array (D-MNA) is a patent protected dissovable transdermal patch with cellulose based microneedle arrays that are tip-loaded with doxorubicin. After application, the microneedles function by penetrating the strateum corneum layer of the skin, create a temporary microchannel, penetrate the tumor, dissolve and release doxorubicin into the target tumor, and eradicate the cancer cells. Squamous Cell Carcinoma (SCC) in Horses SCC is a mucocutaneous skin tumor in horses, primarily affecting adult or aged horses with white or partially white coats. Breeds like Appaloosa, Belgian, American Paint, and Pinto are particularly susceptible. SCC often develops in areas with minimal pigmentation and sparse hair, notably around mucous membranes. More specifically, tumors are mainly seen around the eyes, lips, nose, anus, and external genitalia. The overall incidence of SCC is 2-3% and recent estimates of the US horse population range from 6.6 to 7.25 million horses. Current treatment includes surgery to remove the largest mass, cryotherapy of the smaller mass, and local injection of a chemotherapy drug. In some cases, a topical chemotherapeutic drug will be prescribed in the form of drops (tumors near the eye) or cream (tumors in other parts of body). Additionally, some horses are put on an oral drug called piroxicam that may slow the return of the cancerous cells.
