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.

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.

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

Yes

Genders Eligible for Study

Description

Inclusion Criteria:

  • Body weight between 40 kg and 100 kg inclusive at screening and upon initial confinement.
  • Body Mass Index (BMI) is >= 18.0 to <= 32.0 kg/m2 after rounding to the tenths decimal at Screening. BMI is calculated as weight in kg divided by the square of height measured in meters.
  • A condition of general good health, based upon the results of a medical history, PE, vital signs, laboratory profile and a 12-lead ECG.
  • A female must not be pregnant, or breastfeeding and is not considering becoming pregnant or donating eggs during the study or for approximately 125 days after the last dose of study treatment.

Exclusion Criteria:

  • History: of epilepsy, any clinically significant cardiac, respiratory (except mild asthma as a child), renal, hepatic, gastrointestinal, hematologic or psychiatric disease or disorder, or any uncontrolled medical illness.

  • Participant has any clinically significant ECG abnormalities including the following:

    • Evidence of 2nd or 3rd degree atrioventricular (AV) block at screening visit or upon initial confinement.
    • QT interval corrected for heart rate (QTc) using Fridericia's correction formula (QTcF) ˃ 450 msec (males) or ˃ 460 msec (females) at screening visit or upon initial confinement.

  • History of any clinically significant sensitivity or allergy to any medication or food.

  • Evidence of dysplasia or history of malignancy (including lymphoma and leukemia) other than successfully treated non-metastatic cutaneous squamous cell, basal cell carcinoma or localized carcinoma in situ of the cervix.

  • History or evidence of active tuberculosis (TB) disease or latent TB infection.

  • History of any clinically significant illness/infection/major febrile illness, hospitalization, or any surgical procedure within 30 days prior to the first dose of study treatment.
