Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

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

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study will assess the safety, tolerability and weight loss associated with XEN-101 in obese men and women.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

  • Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Male or female, age 18 to 60 years, inclusive, at Screening
  2. Body mass index of 30 to 45 kg/m2
  3. Stable body weight for at least 3 months (i.e., fluctuation of ≤5%)
  4. If a female of childbearing potential, must agree to use double barrier contraception (e.g., condom and 1 additional form of adequate contraception) from the date of signing of the ICF, throughout the study, and for 4 weeks after the final dose of study drug. In addition, she must be advised not to donate ova during this period. If a non-sterilized male is sexually active with a female partner of childbearing potential, he must use double barrier contraception from the date of signing of the ICF, throughout the study, and for 8 weeks after the final dose of study drug. In addition, he must be advised not to donate sperm during this period
  5. If a female of childbearing potential, must have a negative pregnancy test at Screening and on Day 1 (baseline)
  6. Able to provide informed consent
  7. Willing and able to comply with this protocol and procedures, including feces collection, and be available for the entire duration of the study

Exclusion Criteria:

  1. Currently enrolled in another investigational device or drug study, or less than 30 days or 5 times the half-life of the drug candidate (whichever is longer) has passed between Screening for this study and the end of the Treatment Period of the previous investigational device or drug study
  2. Diagnosed with type 1 diabetes or type 2 diabetes (T2D) (resolution of T2D >3 years before Screening is allowed)
  3. Laboratory evidence during Screening of T2D, including glycated hemoglobin (HbA1c) ≥6.5% or fasting glucose ≥126 mg/dL (≥7.0 mmol/L)
  4. Evidence of clinically significant cardiac, neurologic, psychiatric, pulmonary, renal, hepatic, endocrine, metabolic, or gastrointestinal disease that, in the Investigator's opinion, would compromise the safety of the subject, interfere with the interpretation of the study results, or otherwise preclude subject participation
  5. Female who is pregnant, nursing, or intends to become pregnant during the study.
  6. Positive result for hepatitis B virus surface antigen, hepatitis C virus ribonucleic acid, and human immunodeficiency virus (HIV) antibody at Screening
  7. Use of anti-obesity medications (e.g., glucagon-like peptide-1 analogues, stimulants, bupropion/naltrexone) within 6 months before Screening

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
