Filter by:The purpose of this study is to evaluate the efficacy of photodynamic therapy (PDT)in treatment of Basal cell carcinoma (BCC) and recurrence rate after 6 months.
The purpose of this study is to evaluate the efficacy of pdt in treatment of bcc and factors that affect response rate.
Part I was a double-blind, randomized, vehicle-controlled Proof of Concept (PoC) study to evaluate the safety, local tolerability, pharmacokinetics and pharmacodynamics of multiple topical administrations of LDE225 (a specific Smoothened inhibitor) on skin basal cell carcinomas in Gorlin's syndrome patients. Following a 21-day screening period, patients were exposed to multiple doses of topically applied LDE225 twice daily for 4 weeks in a double-blind manner. The patients returned weekly for visits where each BCC was clinically evaluated and digital photographs taken. Local safety and tolerability was also assessed. After the last application of treatment, biopsies were taken from treated (both vehicle and LDE225) BCCs (three per patient) for histology, biomarker evaluation and for pharmacokinetics (skin exposure). In addition, a biopsy from LDE225-treated uninvolved perilesional skin was taken for pharmacokinetic evaluation. In total, 4 biopsies were taken: 2 for histology and biomarker and 2 for PK. Part II of this study consisted of a 21-day screening period, a baseline period (directly before commencing the treatment period) and a treatment period of 6 or 9 weeks, depending on randomization. A clinical assessment was performed on site on the last treatment day and if a full clinical response had been observed, approximately 3 weeks after the last treatment an excision of the BCC(s) would have been performed. The study completion visit occurred either 1 week after the excision (when this visit was planned) or 1 week after the last treatment. For a subset of patients, skin biopsies were collected on the last treatment day and an excision of a BCC was also performed at that same visit.
This was a multicenter, open-label extension study. Patients who received vismodegib (GDC-0449) in a Genentech-sponsored study and who had completed the parent study or who continued to receive vismodegib at the time the parent study closed were eligible for continued treatment in this protocol.
Basal cell carcinoma (BCC) is the most common skin cancer in the US and can cause significant adverse effects. Mohs micrographic surgery, the treatment of choice for higher risk BCC, allows for removal of lesions with preservation of healthy tissue. Although the BCC recurrence rate post Mohs surgery is estimated at 1-2%, recent data is lacking to validate this historical measurement. Our purpose is to determine the current recurrence rate of BCC after Mohs surgery.
This first-in-human dose-escalation study is to characterize the safety, tolerability, pharmacokinetics and pharmacodynamics of LDE225 given orally on a daily dosing schedule in patients with advanced solid tumors.
The purpose of this study is to estimate and define the mean number, degree of confluence, and depth of penetration of melanocytes in chronically sun exposed skin of the head and neck using Mart-1 immunostains on frozen sections. The study was conducted to confirm whether similar results were found using permanent sections. The present study used hematoxaline and eosin (H&E) staining as well as Mart-1 staining, and included patients from both Mayo Clinic Jacksonville and Rochester.
The main purpose of this study is to see if 5-fluorouracil (5-FU) skin cream can prevent the growth of new skin cancers on the face and ears. The cost of trying to prevent skin cancer will be compared to the usual cost of treating skin cancer. Participants are being asked to be a part of this study because the participants have been treated for two or more skin cancers within the past five (5) years. At least one of these cancers occurred on the face or ears. Having had two or more skins cancers in the past 5 years makes it likely that participants will develop additional skin cancers in the future. Exposure to ultraviolet radiation from the sun or artificial sources such as tanning beds is a major cause of basal cell and squamous cell carcinoma of the skin. Using lotions, creams, or gels that contain sunscreens can help protect the skin from premature aging and damage that may lead to skin cancer. The 5-FU skin cream used in this study is FDA-approved to treat some types of skin cancers and spots that might become skin cancer. However, 5-FU skin cream has never been studied to see if it can prevent skin cancer. This drug is not approved by the FDA for how it will be used in this study. In this study, one half of the patients will use the 5-FU cream and the other half will use a skin cream that looks identical to the 5-FU cream but does not have 5-FU or any other active drug in it. Approximately twelve VA medical centers will work together in this study. About one thousand (1000) patients will be in this study. The study is sponsored by the U.S. Department of Veterans Affairs Cooperative Studies Program.
The purpose of this study is to determine the difference of skin carotenoid levels between subjects with previous squamous cell carcinomas (SCC), subjects with previous basal cell carcinomas (BCC) and a control group.
This was a Phase II, single-arm, two-cohort multicenter clinical trial evaluating the efficacy and safety of vismodegib (GDC-0449) in patients with advanced basal cell carcinoma. All patients received vismodegib until evidence of progression, intolerable toxicities most probably attributable to vismodegib, or withdrawal from the study.
