Evaluation the Effects of Various Treatments on RZL-012-Induced Adverse Events

In the first stage of the study, 5 subjects will be randomized into each of the treatment groups. Study outcomes will be assessed up to one week thereafter to determine the need to modify additional study treatments. Subsequently up to 10 additional subjects will be randomized into each of the treatment groups for the second stage of the study.

For each subject, the study will consist of a screening period, baseline period in which subjects will receive a single treatment session of RZL-012 and a follow-up period. RZL-012 will be administered during a single treatment session via multiple injections into the submental area under the chin. Subjects will thereafter be monitored for safety and efficacy for at least 84 days.

Each subject will be treated with the same dose of RZL-012 :

• RZL-012 (concentration of injected solution 50 mg/mL RZL-012) of 7.5 mg/0.15 mL/injection point that results in a total dose/volume of 240±30mg mg/4.8±0.6 mL RZL-012, Each subject will receive additional study treatments in accordance with the treatment group to which the subject is randomized.
