For the purposes of study treatment and evaluation, these lesions should be limited to the facial treatment area. All lesions will be counted, including those present on the nose. Subjects may have acne lesions on other areas of the body which will also be excluded from the count, treatment, and the Investigator's Global Assessment (IGA) evaluation (e.g., on the back, chest and arms).

- Subjects must be willing to refrain from using all other topical acne medications or antibiotics during the 12-week treatment period for acne vulgaris, other than the Investigational Product.
- Female Subjects of childbearing potential (excluding women who are premenarchal, surgically sterilized or postmenopausal for at least 1 year), in addition to having a negative urine pregnancy test, must be willing to use an acceptable form of birth control during the study from the day of the first dose administration to 30 days after the last administration of study drug . For the purpose of this study the following are considered acceptable methods of birth control: oral or injectable contraceptives, contraceptive patches, Depo-Provera® (stabilized for at least 3 months) NuvaRing® (vaginal contraceptive);Implanon™ (contraceptive implant), double barrier methods (e.g. condom and spermicide),Intrauterine Device (IUD), Essure, or abstinence. If a subject who was abstinent becomes sexually active during the study, a 2nd acceptable method of birth control should be documented. A sterile sexual partner is NOT considered an adequate form of birth control. Hormonal contraceptives should not be initiated or changed during the study.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Dapsone gel 7.5% (Torrent Pharmaceuticals Ltd) and ACZONE® (dapsone) gel, 7.5% (Allergan, INC.) in people with Acne Vulgaris, run by Torrent Pharmaceuticals Limited at 13 sites in 2 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 10 inclusion and 38 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 2 Apr 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 13 sites in United States, Belize. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in inflammatory lesion counts (time frame: 12 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Apr 2020.
