Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The objectives of this trial are to evaluate the safety and tolerability of ATX-101 injections and to characterize the pharmacokinetic profile of the two ATX-101 formulations that are expected to be the final formulations. ATX-101 will be administered into the submental fat as subcutaneous injections using the maximum proposed dosing regimen that is intended for labeling.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Presence of sufficient submental fat into which 50 subcutaneous injections of ATX-101 spaced on a 1.0-cm grid can be safely administered based on the investigator's judgment.
  • Males or nonpregnant, nonlactating females who are aged 18 to 65 years, inclusive, on the date of dosing with ATX-101. Females must have a negative serum human chorionic gonadotropin (hCG) test result from a sample obtained during the screening period and after admission to the research facility, but before the dose of study material. Females of postmenopausal status must not have had menses for at least one year and if younger than 55 years of age must have a serum FSH level ≥ 35 mIU/mL. Females of childbearing potential must agree to practice adequate contraception, in the judgment of the investigator, during the course of the trial.
  • Serum hemoglobin test result of 11.0 g/dL or greater and negative hepatitis B, hepatitis C, and HIV test result within 28 days before the dose of study material.
  • Willing and able to comply with and understand the visit schedule and all of the protocol-specified tests and procedures.
  • Medically able to undergo the administration of study material as determined by clinical and laboratory evaluations obtained within 28 days before dosing with study material for which the investigator identifies no clinically significant abnormality.
  • Signed informed consent obtained before any study-specific procedure is conducted.

Exclusion Criteria:

  • 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, which in the judgment of the investigator may affect evaluation of safety of treatment.
  • Loose skin in the neck or chin area for which reduction in submental fat may, in the judgment of the investigator, result in a cosmetically unacceptable outcome.
  • Prominent platysmal bands at rest that interfere with the evaluation of submental fat.
  • Evidence of any cause of enlargement in the submental area other than localized subcutaneous fat.
  • Body mass index (BMI) > 40.0 at the screening visit. Refer to Appendix B.
  • Use of tobacco or nicotine-containing products within 3 months prior to dose.
  • Any blood donation or significant blood loss within 56 days before the dose of study material or plasma donation within 7 days before the dose of study material.
  • A result on coagulation tests (PT, PTT) obtained within 28 days before the dose of study material that indicates the presence of any clinically significant bleeding disorder.
  • Any medical condition that would interfere with the assessment of safety in this trial or would compromise the ability of the subject to undergo study procedures or to give informed consent.
  • Treatment with fish oil, aspirin, or nonsteroidal anti-inflammatory agents (NSAIDS), except acetaminophen, within 7 days before dosing, or any anticipated need for agents with anticoagulative effects (e.g. warfarin, heparin) during the course of the trial.
  • Treatment with oral anticoagulants (e.g. warfarin) within 30 days before dosing with study material.
  • Treatment with radio frequency, laser procedures, chemical peels, or dermal fillers in the neck or chin area within 12 months before dosing with the study material, or botulinum toxin injections in the neck or chin area within 6 months before dosing with the study material.
  • History of sensitivity to any components of the study material.
  • History of drug or alcohol abuse, in the judgment of the investigator, within two years before dosing with the study material.
  • Presence of a positive urine drug or alcohol screening test result obtained from a sample obtained during the screening period and/or after admission to the research facility for the confinement period, but before dosing with the study material.
  • Previous enrollment into a trial of ATX-101.
  • Treatment with an investigational device or agent within 30 days before dosing.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure

Safety of ATX-101 injections as assessed by incidence, severity and duration of AEs of ATX-101 administered into subcutaneous fat in the submental and abdomen area
Time Frame: 8 days
Spontaneously reported adverse events, laboratory test results, and treatment area evaluations including, but not limited to evaluation of edema, bruising, dysphagia, dysphonia, erythema, dyspigmentation, induration, numbness, pain, paresthesia, and pruritus.
