Sponsored by CAGE Bio Inc. · Phase 2, Interventional, and Treatment
This is a multicenter, randomized, double-blind, vehicle-controlled, parallel design study evaluating the efficacy and safety of CGB-400 Topical Gel for the treatment of inflammatory lesions of rosacea. The study consists of a 12-week double-blind treatment period with clinic visits at Baseline (Day 0), and Weeks 2, 4, 8, and 12.
Approximately 80 subjects will be enrolled and randomized at a 1:1 ratio to treatment with either CGB-400 Topical Gel (40%) BID or Vehicle Gel BID.
233 studies on the registry are indexed under Rosacea; 23 are open to participants now.
This study's enrollment of 78 is above the median of 61 across 200 interventional studies indexed under Rosacea.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
A planned gap after a treatment, so that its effects can lessen before the study treatment or a study assessment. Ask the study team and the doctor who prescribed it before changing any medicine.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
