OrthoTrophix Presents the Key Data of the TPX-100 Phase 2 Study as a Late Breaking Abstract at American College of Rheumatology Annual Meeting

Oakland, Calif., November 7, 2017—OrthoTrophix, Inc., a privately held biopharmaceutical company, announced today that the company and its collaborators present the key data of the Phase 2 study of TPX-100 in subjects with knee osteoarthritis (OA) as a late breaking-abstract at American College of Rheumatology (ACR/ARHP) Annual Meeting currently held in San Diego, CA.

Based on this double-blinded, placebo-controlled, multi-center study, data are presented from 93 subjects with bilateral knee OA who received 4 weekly doses of TPX-100 by intra-articular administration in one knee and identical placebo injections in the other, with at least one follow-up evaluation at 6 and 12 months. Knee injury and Osteoarthritis Outcome (KOOS) scores, and use of non-steroidal analgesics are presented. By way of background, pre-clinical data from earlier animal models are also presented, demonstrating articular cartilage formation in the knee after experimental cartilage injury in goats.

Of note, knee-related activities of daily living (KOOS ADL scores) were significantly improved in TPX-100-treated knees compared with placebo exposed knees (p = 0.008 at both 6 and 12 months). While TPX-100 has no direct analgesic activity, pain when going up and down stairs, the most common complaint in knee OA, was significantly improved (p = 0.004), in TPX-100-treated knees at 12 months. Subjects’ use of NSAIDs declined by over 60% during the study period compared to the pre-dosing period.

The Company’s Chief Medical Officer, Dawn McGuire, M.D. stated, “The robust and sustained improvements in knee function are notable, as is the excellent safety and tolerability profile of TPX-100. Pain alleviation was somewhat unexpected and reasonably can be attributed to improved joint function. We are planning a Phase 2/3 study to confirm these striking results."
