Laurent Pharmaceuticals Presents Results from Phase 2 Clinical Study of LAU-7b in Cystic Fibrosis at the NACFC 2022
MONTREAL, QC, Canada – November 3rd, 2022 – Laurent Pharmaceuticals Inc., a clinical-stage biopharmaceutical company developing LAU-7b (oral fenretinide) as a first-in-class inflammation-controlling drug candidate for Cystic Fibrosis (CF), announces the presentation of results from its placebo-controlled Phase 2 APPLAUD 24-week clinical study in adults with CF at the North American Cystic Fibrosis Conference (NACFC) currently held in Philadelphia, United States.
Study results achieved a statistically significant treatment difference in favour of LAU-7b in the absolute change in the percent predicted forced expiratory volume in one second (ppFEV1), the primary variable, through 24 weeks (1.23 percentage points; p=0.0486) in people that completed at least five months of treatment (Per Protocol population, N=122), and a clinically meaningful reduction of 49% in the loss of lung function at 24 weeks, relative to placebo. Statistically significant clinical benefit was also observed in the relative change in ppFEV1 through 24 weeks (2.34 percentage points; p=0.0351), as well as in the plasma levels of C-reactive protein (p=0.029), an important marker of systemic inflammation. Pre-specified subgroup analysis suggests a higher benefit in subjects with ppFEV1 greater than 70% at baseline, and the effect appears to be maintained in the subgroup of subjects already receiving CFTR modulators, including TRIKAFTA®. The results also passed robustness analyses, despite heterogeneous study population and pandemic interference. The study confirmed that LAU-7b has a predictable and acceptable safety profile, with no unexpected serious adverse events reported.
