We have utilized this composite-based endpoint and associated guidelines, among other measures, in the evaluation of our Phase 2 results.
Improvement in chronic low back pain. At 12 months, a responder analysis showed that there was clear separation between both treatment groups and both control groups at every decile increase in response beyond the MICD of 30% reduction in pain from baseline. In line with guidance from KOLs and from payers, a responder analysis was performed targeting at least 50% reduction in pain from baseline. At both 6 and 12 months, a reduction in pain from baseline of 50% or more, without any additional intervention, was seen in 59.3% of the MPC-06-ID group, 44.8% of the 18 million MPC group, 18.8% of the saline group, and 15.8% of the HA group, as measured by visual analog scale, or VAS (p = 0.006 across all four groups, p=0.023 for 6 million MPC against saline and p=0.006 against HA). Statistical significance denotes the mathematical likelihood that the results observed are real and not due to chance.
