Primary endpoint met statistical significance in corrected topline efficacy data of phase III ROMAN trial of avasopasem.
The Company previously announced the Phase III ROMAN trial of avasopasem in SOM did not achieve statistical significance on the primary endpoint. Upon further analysis, an error by the contract research organization (CRO) was identified in the statistical program. Correction of this error resulted in improved p-values for the primary and secondary endpoints.
The corrected p-values are as follows: i.16% relative reduction in the incidence of SOM in the avasopasem treatment group (54%) vs. placebo group (64%) (p=0.0451) (previously reported as p=0.113) (primary endpoint). ii. 56% relative reduction in the number of days of SOM in the avasopasem treatment group (8 days) vs. placebo group (18 days) (p=0.0022) (previously reported as p=0.011) (secondary endpoint). iii. 27% relative reduction in the severity (incidence of Grade 4 OM) of SOM in the avasopasem treatment group (24%) vs. placebo group (33%) (p=0.052) (previously reported as p=0.167) (secondary endpoint).
The Company also announced topline results from its single-arm Phase IIa EUSOM trial of avasopasem in Europe for RT-induced SOM in patients with HNC undergoing standard-of-care RT + cisplatin. This trial was conducted in 12 centers across six countries in Europe and enrolled 38 patients, of which 33 completed full treatment. Avasopasem appeared to be generally well tolerated. In EUSOM, the incidence of SOM was 54.5% and the median number of days of SOM was 9 days, in line with the ROMAN trial in which the incidence was 54% and the median duration was 8 days.
