The purpose of this research study is to learn if adding all-trans retinoic acid (tretinoin) to conventional treatment of Anti- Neutrophil Cytoplasmic Autoantibodies (ANCA) vasculitis can decrease the level of disease activity.
To determine and compare the safety and efficacy of broad area photodynamic therapy with aminolevulinic acid (ALA-PDT) following topical retinoid pre-treatment vs ALA-PDT with occlusion only (no pretreatment) in subjects with dorsal hand/forearm actinic keratoses, with an incubation time of 60 minutes, using blue light.
The purpose of this study is to evaluate the tolerability of a combined regimen of a topical antibiotic and retinoid and a benzoyl peroxide wash.
The purpose of this study is to investigate the safety and efficacy of alitretinoin in the treatment of severe chronic hand eczema that does not respond to treatment with potent topical steroids.
This study plans to learn more about a drug called bexarotene for the treatment of advanced thyroid cancer. Subjects are asked to be in this study because they have thyroid cancer that will not respond to radioactive iodine therapy and shows signs of aggressive behavior. Bexarotene has been FDA approved for the treatment of a type of skin cancer called cutaneous T-cell lymphoma, but has not been FDA approved for this use. Bexarotene is investigational in the treatment of thyroid cancer. The purpose of this research study is to test how well the study drug works in humans. The study doctors want to know if: 1. The subjects thyroid cancer gets smaller while you are taking the study drug. 2. The subjects thyroid cancer takes up radioactive iodine better after treatment with the study drug than before treatment.
The safety and efficacy of combining NRX 195183 with arsenic trioxide in treating untreated APL will be assessed.
This 2 arm study will investigate the efficacy, safety and tolerability of RAR Gamma versus placebo in ex-smokers with moderate or severe emphysema treated with optimal COPD therapy. Following optimization of COPD therapy (up to 6 weeks) patients will be randomized to receive either RAR Gamma (5mg) or placebo once daily using a 2:1 ratio (active:placebo), in addition to their standard therapy. Following the double-blind treatment period, patients will enter a 4-week follow-up period. The anticipated time on study period is 1-2 years, and the target sample size is 100-500 individuals.
This is a pilot study of retinoids for patients with unsatisfactory response to conventional treatment of nephrotic syndrome due to focal segmental glomerulosclerosis or minimal change disease, two renal disorders associated with putatively pathogenic malfunctioning of glomerular podocytes. The hypothesis that retinoids may have reparative effects on these cells is based on previous research showing that retinoids promote the differentiation or redifferentiation of aberrant epithelial cells. Results obtained by 6 months of treatment with retinoids (that have been approved for non-renal indications) will be used as preliminary information upon which to base further testing of these agents in formal clinical trials in refractory cases of these nephrotic syndromes.
This study is being conducted to confirm whether skin tape stripping methodology can identify changes in gene expression (i.e. whether different genes are turned on to make proteins) in aged skin after use of a retinoid.
Sun-damaged skin, caused by chronic exposure to ultraviolet (UV) light, is characterized by features such as wrinkling, uneven skin color, roughness and brown spots. An effective treatment for sun-damage that is commonly prescribed is topical retinoic acid (RA). However, the major drawback of topical RA use has been frequently observed irritation characterized by redness, dry skin and severe itching. In this study, we examine whether a daily skin care regimen comprised of an ultra mild cleanser and an effective moisturizer can help improve tolerance to RA treatment.
Psoriasis is a common skin disease that can affect 1-3% of the population. For more severe psoriasis, oral medication such as acitretin is sometimes given. While acitretin may be sufficient for treatment of some patients, psoriasis of the palms and soles is particularly challenging to treat, and may not respond to acitretin alone. In this study, the focus is on patients who have psoriasis of the palms and soles, and are currently taking acitretin. The aim is to initially recruit 10 patients and offer them treatment with a laser, the excimer laser, to one palm and one sole. Patients will receive laser treatment twice weekly for a total of 8 weeks, while also taking their acitretin tablet. If the side treated with the excimer laser shows greater improvement compared to the other side, the second part of the study will be conducted. In this second part, another 15 patients will be included. These patients will receive twice weekly treatments with the excimer laser to one both palms and/or soles, for a total of 8 weeks. The aim is to prove that the addition of excimer laser to treatment with acitretin will lead to greater improvement of psoriasis on palms and soles.
This is an open label study of isotretinoin, a medication which is FDA approved for treatment of other conditions to determine initial safety in Alzheimer's disease.
Our study aims to evaluate if the consumption of a Fruit and Vegetable Juice Concentrate (FVJC) vs. placebo can exert changes in the serum levels of Retinol Binding Protein 4 (RBP4), carotenoids, tocopherol, antioxidant capacity, pro-inflammatory markers, insulin sensitivity in conjunction with weight management in a cohort of lean as compared to overweight healthy six to ten year-old boys. The boys will undergo a detailed medical and family history and a complete physical examination during the screening visit. Careful anthropometric measures and body composition by DEXA will be performed. Nutritional and exercise counseling will be given at the start of the study. The outcome measures will include differences in serum RBP4, antioxidant levels, inflammatory markers and insulin sensitivity at baseline and six months after consumption of FVJC in a randomized double blind placebo control manner.
The purpose of this study is to determine whether NRX 195183 is effective in the treatment of relapsed or refractory Acute Promyelocytic Leukemia
Parapsoriasis is a term that refers to a precursor stage of cutaneous T-cell lymphoma (CTCL)/mycosis fungoides(MF). Complete responses (clearing) of early presentations of CTCL/MF have been shown to be associated with long-term survival and cure. Induction of a complete response in parapsoriasis, therefore, would seem to be a desirable therapeutic endpoint. Bexarotene 1% gel has been approved for treatment of cutaneous T-cell lymphoma (mycosis fungoides). The goal of this study is to evaluate the tolerability, safety and efficacy of bexarotene 1% gel in patients with parapsoriasis.
This study evaluates the use of Targretin capsules (bexarotene) in combination with standard chemotherapy for the treatment of metastatic Non-Small Cell Lung Cancer (NSCLC) in patients who have not yet received chemotherapy for their lung cancer.
This study evaluates the use of Targretin capsules (bexarotene) in combination with standard chemotherapy for the treatment of metastatic Non-Small Cell Lung Cancer (NSCLC) in patients who have not yet received chemotherapy for their lung cancer.
A body of preclinical data has provided a strong rationale for evaluating the combination of IFN-alpha with retinoic acid. The two drugs have different mechanisms of action and, when used in combination, show enhanced activity in both adult and pediatric tumor cell lines. The combination of the antiproliferative and differentiation inducing effect of retinoids together with the antiproliferative, immunostimulatory and differentiation-potentiating effects of IFN-alpha warrant clinical investigation of this combination for the treatment of refractory pediatric malignancies.
This is a dosage escalation study to estimate the maximum tolerated dose of 9-cis-retinoic acid given in combination with tamoxifen. Groups of 3 to 6 patients receive oral 9-cis-retinoic acid daily for 4 weeks, after which daily oral tamoxifen is added to the regimen. Patients continue treatment for up to 28 weeks, with tamoxifen continued after the study if medically appropriate.
Psoriasis is a chronic skin disorder with a prevalence of approximately 1-3% worldwide. At present, there is no curative therapy available and the clinical course is unpredictable, but in the majority of cases psoriasis is a chronically remitting and relapsing disease. Several clinical subtypes of psoriasis exist with differences in manifestations and skin areas involved. Chronic stable plaque psoriasis (Psoriasis Vulgaris) is the commonest form of the disease, accounting for 85-90% of cases. The circumscribed infiltrated skin lesions are scaly and erythematous and often symmetrically distributed over the body. Several types of palliative therapies exist. The therapies are either topical or systemic. The severity of chronic plaque psoriasis is often determined by the percentage of body surface area (BSA) involved. For mild, moderate and severe chronic plaque psoriasis with BSA involvement of up to 20%, initial therapy is topical. Phototherapy and numerous systemic therapies are usually indicated when more than 20% of skin is affected. Severe plaque-type psoriasis requires systemic and long-term therapy in order to induce and maintain remission. Acitretin 25mg/day combined with a phototherapy regimen is a standard treatment that provides clinically significant efficacy, however many patients experience tolerability issues due to retinoid-related adverse events. Retinoid-related adverse events include but are not limited to: alopecia, dry mucus membranes, pruritus, photosensitivity, elevation of liver enzymes, elevation of serum triglycerides, cholesterol and decrease of HDL, arthralgias, myalgias, eye irritation, blepharitis, photophobia, conjunctivitis, headaches, nausea, anemia and leukemia. Reducing the acitretin dose from 25mg/day to 17.5mg/day may provide improved tolerability without compromising efficacy. The purpose of this study is to ascertain if reducing the acitretin dose from 25mg/day to 17.5mg/day will provide improved tolerability without compromising efficacy.
Topical therapy with retinoids is the only proven medical therapy for aged/photoaged human skin. However, topical therapy with retinoids often result in unwanted cutaneous dermatitis, including erythema and scaling. The reseachers intend to investigate the dose, frequency of use, and time dependence of topical retinol-induced dermatitis. The researchers intend to evaluate retinoid-induced dermatitis biochemically, including retinol regulation of retinoid responsive genes that control retinoid metabolism and serve as markers for retinoid bioactivity. The researchers will also investigate the role of EGF receptor pathway in retinoid-induced dermatitis.
The purpose of the study is to compare the efficacy of three maintenance regimens (topical tazarotene, oral minocycline, or both) in sustaining improvement in acne.
