Filter by:In an 8 week double blind randomized controlled split-face studies, we tried to compare the clinical efficacy, safety and histopathological changes between Lactobacillus fermented Chamaecypris obtusa (LFCO) and existing tea tree oil (TTO) Basically, this is a split face study - one side of face randomly assigned was applied with LFCO and the other side with TTO in same patients.
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.
The purpose of this study is to determine the response of acne patients and healthy control patients to the P. acnes bacteria. Half a tube of blood will be drawn from all participants to determine whether or not they have antibodies to the P. acnes bacterium. Anywhere from 1 to 4 skin biopsies of acne pimples or normal control skin will be taken from all subjects for further analysis in the lab to determine whether the inflammation in these pimples can be reduced using anti-P.acnes antibodies.
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.
This is a multicentre, randomized, assessor-blind, comparator-controlled evaluation of the efficacy, safety, and tolerability of Duac™Once Daily Gel and clindamycin phosphate gel in the topical treatment of mild to moderate facial acne vulgaris. A total of 1020 subjects will be enrolled, 510 per study arm. The subjects will be males and females between 12 and 45 years of age, inclusive, at the time of consent, who have mild to moderate facial acne vulgaris. Subjects will use Duac™Once Daily Gel (once daily in the evening) or clindamycin phosphate gel twice daily (once in the morning and once in the evening) for 12 weeks. The subjects will be evaluated for change in lesion counts, investigator's static global assessment (ISGA), subject's global assessment (SGA), local tolerability and AEs/SAEs at Weeks0, 1, 2, 4, 8, and 12 (or at early withdrawal). In addition, quality of life measures will be performed at every study visit.
This open label study is to determine the safety profile of GK530G in a long-term treatment (up to 12 months) in subjects with acne vulgaris and to evaluate the efficacy of GK530G in a long-term treatment.
The purpose of this study is to determine the tolerability of Cetaphil® DermaControl™ Foam Wash and Moisturizer SPF 30 in pediatric subjects (7-11) with acne prone skin.
This pilot study will explore if continuation of treatment of treatment with Aczone 5% gel following combination treatment with with doxycycline and Aczone 5% gel can maintain therapeutic response.
The study hypothesis are based on the assumption that : - CD0271 0.3%/CD1579 2.5% Gel provides superior clinical efficacy compared with Topical Gel Vehicle in the overall population and in the subgroup of severe Subjects - CD0271 0.3%/CD1579 2.5% Gel applied once daily for up to 12 weeks has an acceptable safety and tolerability profile
This is a 12 week clinical trial in subjects with acne vulgaris. Subjects will be randomized to NVN1000 1% Gel, NVN1000 4% Gel or Vehicle Gel twice daily. Safety, tolerability and efficacy will be assessed over the course of the study.
