Active clinical trials for "Acne Vulgaris"

Clindamycin 1.0% - tretinoin 0.025% gel (CT Gel) is a reformulation of VELAC Gel that contains the same active ingredients (clindamycin 1.0% and tretinoin 0.025%) in a modified vehicle. This was a single-center, evaluator-blinded, randomized, placebo (vehicle)-controlled phase 1 study to evaluate the phototoxic potential of CT Gel using 24 hour single applications of 3 sets of 3 study patches. The study expected to enroll approximately 40 healthy adult volunteers. Each set of study patches consisted of a CT Gel patch, a vehicle gel patch, and a blank patch (did not contain CT Gel or vehicle gel). After concurrent 24-hour single applications of all 9 patches, 1 set of patches (set A) was removed, and those sites were irradiated with 16 joules/cm2 of ultraviolet A light (UVA) and 0.75 minimal erythema dose (MED) with UVA/ultraviolet B light (UVB). The second set of patches (set B) was removed, and those sites were irradiated with 16 joules/cm2 of UVA, 0.75 MED with UVB/UVA, followed by 15 joules/cm2 of visible light (VIS). The third set of patches (set C) was then removed, and those sites served as a non irradiated control. Inflammatory responses and other cutaneous effects were scored 1 hour after patch removal and during follow-up visits at 24, 48, and 72 hours after patch removal.

Exploratory, international, multi-centre, randomized, investigator blinded study in acne

The purpose of this study is to evaluate the irritation level of tazarotene foam after 21 days of exposure on the skin of healthy volunteers.

Open, prospective, randomized, single-centre study in patients with moderate to severe facial acne vulgaris. Three circular areas with a diameter of 4 cm, each circle including at least 4 inflammatory lesions, will be selected in acne-affected areas in the face. One area should be identified on each cheek and one area should be identified on the forehead. The minimum distance between the three areas should be at least 4 cm. For each patient the three areas will be randomized to either a pre-treatment cleaning using a wipe containing an ethyl alcohol solution(one area) or a cleansing wipe containing saline water (two areas), before application of the Visonac cream. One of the areas cleaned with saline wipe will also be occluded with a transparent dressing (Tegaderm) during the incubation time. In vivo fluorescence spectroscopy will be performed in the three areas before cream application, and at 1h, 1.5h, 2h, 2.5h and 3 h after cream application. After the last fluorescence spectroscopy reading, the cream should be wiped off and the patient should protect the three areas from sunlight, prolonged, or intense light for 2 days. The study was extended with additionally 8 patients to explore the photoactive porphyrin levels over a 24 hour period: The patients will clean their face with Cetaphil Gentle Skin Cleanser before cream application. For each patient the three areas will be randomized to Visonac 80mg left on the skin for 24 hours and Visonac (MAL8%) to be wiped of after 1 hour. In vivo fluorescence spectroscopy will be performed at all three areas before cream application, and at 2h, 3 h, 4h, 5h, 8h, 10h, 11h, 12h, 13h, 15 and 24h after cream application. The exact time points may be adjusted based on the result from the previously included patients. All patients will be instructed to protect the three areas from sunlight, prolonged, or intense light for 2 days.

The purpose of this study is to investigate how pretreatment with a topical medication for acne affects application and delivery of gold microparticles to the skin in acne patients. In addition, the investigators want to investigate the biodistribution of gold microparticles in pretreated skin and compare this with the biodistribution of untreated skin using the non-invasive imaging techniques optical coherence tomography and reflectance confocal microscopy

Exploratory, multi-center, randomised, investigator-blinded, vehicle controlled study using intra-individual comparison involving subjects with acne vulgaris on face to evaluate the efficacy of CD5024 1% cream over a 6-week treatment period compared to its vehicle.

In this study, The Investigator will be assessing the efficacy and tolerability of Rehmannia glutinosa Libosch leaf-based extract formulation consumption on the treatment of Acne Vulgaris in a randomized, double-blind, placebo-controlled study for the duration of 56 days.

This study will evaluate the safety, tolerability, and pharmacokinetics (PK) of dapsone in subjects with acne vulgaris following 28 days of dosing.

Acne vulgaris is a chronic inflammatory disorder of the skin in the pilosebaceous unit of the hair follicle, associated with oil production. It is found across skin types and is present in 85% of adolescents, representing a large affected population. Because of the universal nature of the disease, 36.3% of acne patients come from backgrounds other than Caucasian. The purpose of this study is to examine patient knowledge about acne in different populations and to assess the effectiveness of a teaching intervention on acne knowledge. The investigators aim is to better understand and subsequently reduce any potential health disparities within the minority populations. This project will evaluate differences in acne knowledge between different ethnic groups, and the efficacy of an educational intervention. Subjects will first complete a survey evaluating their knowledge of acne and how acne affects them psychosocially before an educational intervention. Immediately following the intervention, the patient's knowledge of acne will be evaluated again. Finally, two months after the intervention, a phone call will be made evaluating their retention of the education materials and their quality of life related to psychosocial effects of acne. Investigating this educational intervention and any current disparities in acne education and understanding will better allow us to educate and treat acne patients in the future.

This was a single-center, evaluator-blinded, randomized, placebo (vehicle) -controlled phase I study to evaluate the photoallergic potential of Clindamycin-Tretinoin Gel. The design consisted of the following periods: screening, induction, rest, challenge, and rechallenge (if indicated). Induction visit 1 was to occur within 5 days of screening visit 2. The study expected to enroll approximately 62 healthy adult volunteers. Subjects were to receive repeated 24-hour study patch applications; after patch removal, the sites were irradiated with ultraviolet B light (UVB) and visible light (VIS) during the induction period (consisting of 6 consecutive induction phases), and ultraviolet A light (UVA)/ UVB and VIS during the challenge and rechallenge periods. Each application site was observed approximately 1, 24, 48, and 72 hours later for signs of inflammation.
