Evaluation of Safety and Efficacy of RZL-012 in Subjects Seeking Fat Reduction in the Flanks

This clinical trial is comprised of a double-blind, placebo-controlled phase followed by an open-label phase.

The double-blind, placebo-controlled phase of the trial will consist of a screening period, baseline visit and a 12-week post-treatment follow-up period. At the baseline visit, each flank (right and left) of each study participant will be randomized into either the active RZL-012 treatment group or the placebo group and each flank will receive multiple injections in a single session of RZL-012 or placebo. Blood samples will be collected for 6 of the 12 subjects for PK analyses. All subjects will be followed up for 12 weeks after the single treatment session.

Upon completion of the double-blind phase of the study, and the opening of codes subjects will be offered RZL-012 open-label treatment in the flank previously treated with placebo. Consenting subjects will be followed for safety and efficacy for an additional 12 weeks.

In both the double-blind and open-label phases of the study, subjects will be monitored for adverse events (AEs). Subjects will return to the site for visits at 1 week, 4 weeks, 8 weeks, and 12 weeks post treatment and will be monitored for safety and efficacy during these visits.

Subjects who will be collected with PK will return to the clinic at Day 1 post injection for further PK samples.

The dimensions of flanks will be measured using 3D images and volumetric calculations using Canfield 3D images.
