Study Details

Study Description

Brief Summary

A total of 12 subjects will be injected with RZL-012 and placebo. Each of the subject's flanks will be randomized for each of the treatment. A total of 24 flanks will be randomized in the double blind phase. They will be monitored for safety and efficacy for 12 weeks. After codes opening, a second treatment cycle on the previously untreated contralateral flank will be done. Subjects will be monitored for safety and efficacy for additional 12 weeks.

Condition or Disease Intervention/Treatment Phase
Phase 2

Detailed Description

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.

Arms and Interventions

Arm Intervention/Treatment
Active Comparator: RZL-012 50mg/ml

Subjects flanks treated with RZL-012 (in the double blind phase) will undergo a single treatment session with 50-55 injections. The maximal number of injections will be 55 with maximal doses 412.5 mg. Each injection point will be dosed with 7.5 mg for in a volume of 0.15 mL/injection site.

Drug: RZL-012
small synthetic molecule for submental fat reduction

Placebo Comparator: Placebo

Subjects flanks treated with placebo (in the double blind phase) will undergo a single treatment session with 50-55 injections. The maximal number of injections will be 55 with maximal volume of 8.25mL. Each injection point will be dosed with 0.15 mL/injection site.

Drug: Placebo

Outcome Measures

Primary Outcome Measures

  1. The incidence of Treatment-related Adverse Events [AEs] [12 weeks]

    Safety

Secondary Outcome Measures

  1. Efficacy - Change in score according Physician Global Assessment Scale [12 weeks]

    To compare the proportion of flanks having an improvement as indicated by reduction in score from 6 to 0 according to the Physician Global Assessment Scale (GAIS) in RZL-01-treated flanks vs placebo-treated flanks

  2. Efficacy - Change in satisfaction score [12 weeks]

    To compare the proportion of subjects who are satisfied with treatment results as indicated by a binary yes/no satisfaction questionnaire in RZL-012-treated flanks vs placebo-treated flanks

  3. Efficacy - fat volume change [12 weeks]

    Measure the mean reduction in volume (mm^3)at post treatment vs. baseline for each of the treated flanks, as measured by 3D images using the Canfield 3D system in RZL-012-treated flanks vs placebo-treated flanks

  4. Efficacy -Change in fat volume [12 weeks]

    Blinded reviewers will identify, per patient, the flank treated with test compound (active) vs the flank treated with Placebo. Success will be defined as at least 70% correct identification vs the expected 50% correct identification based on random guessing

  5. Pharmacokinetics measure - drug concentration in the blood (ng/mL) [30 hours]

    Measurement of maximum drug concentration (Cmax) (ng/mL) in the blood
