Hilltop Bio, Inc., a veterinary biotechnology company based out of Mansfield, MA is creating cutting edge regenerative therapies that are changing the landscape of treatment options for veterinarians and horse owners. Hilltop Bio was founded in 2018 and saw a surge in growth in 2023. The company grew to service 290 practices around the United States and boosted a 225% growth in sales in 2023 all while maintaining their 96% reorder rate amongst veterinarians.

Hilltop Bio’s star products include Regenaflex-RT for soft tissue injuries and Strydaflex for intra-articular joint injections. CEO, Amanda Drobnis, commented, “What makes us unique from the traditional modalities like steroids, PRP, ProStride, etc, is that all our products are custom engineered for specific indications. So the specific proteins and growth factors that are in Regenaflex-RT for soft tissue injuries are different from those in Strydaflex for joints, because there are some proteins you want in a soft tissue product, but not in a joint related product. We saw some phenomenal growth in 2023 as veterinarians and horse owners started to reach for our products more than ever before.”

Regenaflex-RT contains a mixture of anti-inflammatory and growth factors that help support the reconstruction of tissue fibers with minimal scarring. Veterinarians have been pleased with how ultrasound scans look around the 45 day mark. Dr. Beau Whitaker of Brazos Valley Equine conducted a study with Louisiana State University which examined horses with suspensory injuries and were subsequently treated with Regenaflex-RT and shockwave. 80% of the horses treated were sound after 3 months. Dr. Whitaker hosted a webinar for horse owners with Horse Network in January to discuss the results of the study.

Hilltop Bio also makes two wound treatment products; Regenaflex-M and Regenaflex-Gel. Regenaflex-M can be used for larger wounds like this shoulder laceration that Dr. Izzy Wayner of John R. Steele & Associates treated. Regenaflex-Gel can be used for smaller wounds, cuts, and summer sores. These two cases below show summer sores that were resolved in <12 weeks. Regenaflex-Gel is available for horse owners to purchase at
