BACKGROUND Androgenetic alopecia (male pattern hair loss) is caused by androgen-dependent miniaturization of scalp hair follicles, with scalp dihydrotestosterone (DHT) implicated as a contributing cause. Finasteride, an inhibitor of type II 5alpha-reductase, decreases serum and scalp DHT by inhibiting conversion of testosterone to DHT. OBJECTIVE Our(More)
The primary aim of a phase I cancer clinical trial is to determine the maximum tolerated dose (MTD) of a new agent. The MTD is determined as the highest dose level of a potential therapeutic agent at which the patients have experienced an acceptable level of dose limiting toxicity. Although many other types of designs have been proposed in recent years, the(More)
The effects of finasteride, a potent 5 alpha-reductase inhibitor, were assessed in patients with benign prostatic hyperplasia. Patients were treated with finasteride or placebo for 24 weeks in a double-blind multicenter study followed by a 12-month open-extension period. After 24 weeks, finasteride-treated patients, when compared to placebo-treated(More)
BACKGROUND One key objective of a multi-regional clinical trial (MRCT) is to use the trial results to 'bridge' from the global level to local region in support of local registrations. However, data from each individual country are typically limited and the large number of countries will increase the chance of false positive findings. PURPOSE Graphical(More)
BACKGROUND Residual cardiovascular (CV) risk often remains high despite statin therapy to lower low-density lipoprotein cholesterol (LDL-C). New therapies to raise high-density lipoprotein cholesterol (HDL-C) are currently being investigated. Anacetrapib is a cholesteryl ester transfer protein (CETP) inhibitor that raises HDL-C and reduces LDL-C when(More)
A key issue in multi-regional clinical trials (MRCTs) is how to assess the consistency of treatment effect across regions, although there is no a priori reason to believe that the treatment effect should vary across the regions. In this article, we define the research question as an assessment of overall consistency across all regions for which all regions(More)
To minimize potential controversies in determining the need for multiplicity adjustment for multiple hypotheses, we propose a decision rule based multiplicity adjustment strategy in this paper. Resorting to a predefined decision rule of a clinical trial, one may link the different hypotheses by their logical relationships and divide them into different(More)
Eight patients with chronic open-angle glaucoma who had an intraocular pressure greater than 24 mm Hg at some time during the day while taking timolol 0.5% twice daily were given the fixed ratio combination of timolol 0.5% with pilocarpine 2% (TP2) twice daily. By comparing full 24-hour diurnal curves on timolol with those on TP2 it was possible to show(More)
Systemic beta-blockade after single doses of ophthalmic beta-blockers (one drop in each eye) was investigated in healthy volunteers in two randomized, double-blind, crossover, placebo-controlled studies. beta-Blockade was evaluated by displacement of the bronchodilator (specific airway conductance), positive chronotropic (heart rate), and tremorogenic(More)
During the last several decades, the scientific and ethics communities have addressed important ethical issues in medical research, resulting in the elaboration and adoption of concepts, guidelines, and codes. Ethical issues in the conduct of Multiregional Clinical Trials have attracted significant attention mainly in the last two decades. With the(More)
