METHODS: 297 adult women with average 14.4 ± 11.4 stress leaks over 3 days were randomized 2:1 (150x106 AMDC-USR:vehicle PBO) and stratified by baseline severity and prior SUI surgery. AMDC-USR was manufactured from vastus lateralis harvest via outpatient biopsy and injected into the urinary sphincter at a subsequent outpatient procedure. SUI was monitored by 3-day diary of stress incontinence episode frequency (SIEF) and quality of life (QOL) questionnaires. Subjects were unblinded after 12 months, and PBO subjects could receive an open-label AMDC-USR treatment. Subjects were followed for 2 years post initial treatment. RESULTS: 297 women were treated (199 AMDC-USR; 98 PBO), 99% completed 12 months (199 AMDC-USR; 96 PBO), and 85% have completed 2 years (167 AMDC-USR; 86 PBO). 93% PBO subjects opted to receive open-label AMDC-USR treatment. Percentage of SIEF responders by strata, endpoints and visits is presented below. SIEF reduction correlated with improvement in all QOL scores at 12 months (p < 0.001). Treatment-related serious adverse reactions were uncommon (< 1%) with no AMDC-USR safety signals detected. CONCLUSIONS: Single injection of AMDC-USR is safe and durable through 2 years with varying therapeutic effect. Consistent with our previous study, ≥ 50% SIEF reduction is not a sufficient endpoint. High variability in PBO response rates across strata impacts generalizability of the treatment response in the overall population. Nonetheless, there was encouraging response in subjects with > 10 baseline SIE, and a markedly greater percentage (> 2-fold) of women with prior surgery achieved statistical and clinically meaningful ≥ 75% SIEF reduction compared with PBO, further supporting that this population may be ideally suited for AMDC-USR therapy.
