Study Overview

Status

Status

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

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

After a screening visit and a one-week washout (if applicable), three sequential ascending doses of the study drug will be applied twice-daily (BID) for 14 days in three groups of subjects. Each group of subjects will be randomized to receive the planned doses of B244 or placebo BID

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 45 years (ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

    • ≥105 inflammatory lesions
    • ≥10 non-inflammatory lesions

  5. Use of tanning booths or excessive sun exposure, in the opinion of the investigator
  6. Active cystic acne or acne congoblata, acne fulminans, and secondary acne

  10. Treatment with systemic antibiotics or systemic anti-acne drugs or systemic anti-inflammatory drugs within 4 weeks prior to baseline
  11. Prescription topical retinoid use on the face within 4 weeks of baseline (e.g., tretinoin, tazarotene, adapalene)
  12. Treatment with hormonal therapy or dose change to hormonal therapy within 12 weeks prior to baseline. Dose and frequency of use of any hormonal therapy started more than 12 weeks prior to baseline must remain unchanged throughout the study. Hormonal therapies include, but are not limited to, estrogenic and progestational agents such as birth control pills.
  13. Use of androgen receptor blockers (such as spironolactone or flutamide)
  14. Oral retinoid use (e.g., isotretinoin) within 12 months prior to baseline or vitamin A supplements greater than 10,000 units/day within 6 months of baseline
  15. Facial procedures (chemical or laser peel, microdermabrasion, etc.) within the 8 weeks of the first dose or during the study
  16. A positive urine drug screen for drugs of abuse, including alcohol or positive urine cotinine (≥300 ng/mL for cotinine) at the screening visit or at entry to the clinic (Note: urine cotinine required at screening visit only)
  17. Treatment with any investigational drug within 30 days or 5 half-lives (whichever is longer) prior to the beginning of the screening period (this includes investigational formulations of marketed products, inhaled and topical drugs)
  18. Hypersensitivity to B244 or its components
  19. Blood collection of greater than 500 mL within 56 days prior to screening

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.
