BMP7 and osteoarthritis: An encouraging report of symptomatic benefit and general safety and tolerability of BMP-7 injection in patients with osteoarthritis in a 2010 phase I clinical trial provided some proof of potential for—and investor interest in—the “repurposing” of BMP-7 in a rheumatic disease (Hunter et al. 2010) context, but we could not find any more recent reports of clinical trials beyond phase I. The slow progress of BMP-7 through the clinical trial process is likely mainly due to financial considerations.
