Who can join

Age: 18 and older, up to 65. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Submental fat graded by the investigator as 2 or 3 using the Clinician-Reported Submental Fat Rating Scale (CR-SMFRS) and graded by the subject as 2 or 3 using the Patient-Reported Submental Fat Rating Scale (PR-SMFRS) as determined on Visit 1 (within 28 days before randomization).
• Dissatisfaction with the submental area expressed by the subject as a rating of 0, 1, or 2 using the Subject Self Rating Scale (SSRS) as determined on Visit 1 (within 28 days before randomization).
• Males and nonpregnant, nonlactating females 18 to 65 years of age, inclusive, on the day of randomization (Visit 2). Females of childbearing potential must have a negative human chorionic gonadotropin (hCG) test result within 28 days before Visit 2 and agree to practice adequate contraception, in the judgment of the investigator, during the course of the study. Females of childbearing potential who are not sexually active need not practice contraception.
• History of stable body weight, in the judgment of the investigator, for at least 6 months before randomization.
• Expected to understand and agree to comply with the visit schedule and all protocol-specified tests and procedures and agreement by the subject to refrain from making significant changes, in the judgment of the investigator, to his or her dietary or exercise habits during the course of the subject's participation.
• Agreement to forego any treatment or behavior (e.g., unshaven facial hair) during the subject's participation in the study that may affect the assessments of the submental area.
• Medically able to undergo the administration of study material determined by clinical and laboratory tests obtained within 28 days before randomization for which the investigator identified no clinically significant abnormality.
• Signed informed consent obtained before any study-specific procedure is performed.

You may not qualify if…

• History of any intervention to treat submental fat (e.g., liposuction, surgery, or lipolytic agents).
• History of trauma associated with the chin or neck areas that in the judgment of the investigator may affect evaluation of safety or efficacy of treatment.
• A Submental Skin Laxity Grade (SMSLG) of 4 or other anatomical feature (e.g., predominant subplatysmal fat, loose skin in the neck or chin area, prominent platysmal bands), as assessed within 28 days before randomization, for which reduction in submental fat may, in the judgment of the investigator, result in an aesthetically unacceptable outcome.
• Evidence of any cause of enlargement in the submental area (e.g., thyroid enlargement, cervical adenopathy) other than localized submental fat.
• Body mass index of > 40.0 as determined on Visit 1.
• History or current symptoms of dysphagia.
• A result on coagulation tests (PT, PTT) obtained within 28 days before randomization that indicates the presence of any clinically significant bleeding disorder.
• Any medical condition (e.g., respiratory, cardiovascular, hepatic, neurological disease, or thyroid dysfunction) that would interfere with assessment of safety or efficacy or compromise the subject's ability to undergo study procedures or give informed consent.
• Treatment with radio frequency, laser procedures, chemical peels, or dermal fillers in the neck or chin area within 12 months before randomization.
• Treatment with botulinum toxin injections in the neck or chin area within 6 months before randomization.
• History of sensitivity to any components of the study material
• History of sensitivity to topical or local anesthetics (e.g., lidocaine, benzocaine, procaine).
• Previous randomization in this study or previous participation in a Kythera-sponsored ATX 101 trial.
• Treatment with an investigational device or agent within 30 days before randomization.
• For centers selected to conduct magnetic resonance imaging (MRI) evaluations, any subject with the presence of any condition that would render a subject unsuitable for MRI evaluation (e.g., claustrophobia), or metals in the body that would interfere with MRI acquisition (e.g., nonremovable metal appliances in the mouth such as silver or gold caps, pacemakers, metal joints).
