NCT00743795
The purpose of this study is to compare the safety, tolerability and effectiveness of the experimental drug GS-9190 when administered for 24 or 48 weeks with peginterferon alfa 2a and ribavirin for the treatment of genotype-1 chronic hepatitis C infection.
NCT00516321
The purpose of this study is to assess the ability of eltrombopag to maintain a platelet count sufficient to facilitate initiation of antiviral therapy, to minimise antiviral therapy dose reductions and to avoid permanent discontinuation of antiviral therapy. The clinical benefit of eltrombopag will be measured by the proportion of subjects who are able to achieve a Sustained Virological Response (SVR).
NCT00274547
The primary objective of this trial is to determine whether treatment with tiotropium (18 mcg) capsule once daily via the HandiHaler reduces the proportion of patients with COPD experiencing an exacerbation and the proportion of patients hospitalized for an exacerbation during a six month observation period.
NCT00096616
The purpose of this study is to demonstrate the superior bronchodilator efficacy of inhaled Combivent® CFC MDI vs. Albuterol HFA MDI in moderate to severe asthma patients.
NCT00003563
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Gadolinium texaphyrin may increase the effectiveness of radiation therapy by making tumor cells more sensitive to radiation. It is not yet known whether giving gadolinium texaphyrin with radiation therapy is more effective than radiation therapy alone in treating brain metastases. PURPOSE: Randomized phase III trial to compare the effectiveness of radiation therapy with or without gadolinium texaphyrin in treating patients who have brain metastases.
NCT01031680
This study is carried out to assess whether dapagliflozin lowers blood glucose, body weight and blood pressure, when added to patients existing medications and how it compares with their usual treatment without added dapagliflozin. Safety data will be collected and analysed to confirm that treatment with dapagliflozin is safe and well tolerated in patients who have diabetes, cardiovascular disease and hypertension.
NCT00148486
To demonstrate efficacy and dose-response of NS 2330 versus placebo in patients with early Parkinson's Disease in 14 weeks of treatment, and to investigate the safety and tolerability of NS 2330 in these patients.
NCT00922233
A prospective, open-label, single arm, multicenter study to evaluate efficacy, safety and acceptability of pericoital oral contraception with levonorgestrel
NCT00828841
This study is testing the investigational drug, cetuximab, in combination with different chemotherapy drugs for lung cancer. The aim of the study is to determine which of the drug combinations looks most promising and should be tested further. The study will also look at what side effects may occur.
NCT00457392
This study will test whether treatment with erlotinib plus SU011248 is better than erlotinib alone in patients with advanced/metastatic lung cancer who have received previous treatment with a platinum-based regimen.
NCT00375284
This trial is a 6-week, double-blind, randomized, active and placebo-controlled parallel-group study with a primary objective of comparison of starting doses of pramipexole fixed-dose (0.25 mg daily) and pramipexole titrated-dose (0.125 mg qd for 1 week, then 0.25 mg qd for the remaining 5 weeks) with placebo to evaluate efficacy and safety in treating RLS symptoms in patients diagnosed with idiopathic RLS. The secondary objectives of this study will be to assess the onset of action of symptomatic relief of RLS for pramipexole with daily assessment of PGI and modified IRLS during two intervals of the first 2 weeks (Days 2, 3 and 4 and Days 9, 10, and 11) and assessment of IRLS, PGI and CGI-I at Weeks 1, 2, 4 and 6 (CGI-I additionally on Day 3).
NCT01197794
The study will assess the efficacy, safety and tolerability of AZD1981 compared to non-active compound in asthmatic patients.
NCT01136655
This purpose of the study is to investigate the bronchodilating effects of 3 different dosages of formoterol given in combination with budesonide as Symbicort pMDI.
NCT00032643
Congestive heart failure (CHF) affects 4-5 million Americans, and its prevalence is predicted to increase over the next few decades. Thyroid hormone has unique actions which make it a novel and potentially useful agent for treatment of CHF. Due to possible adverse affects of thyroid hormone, there is interest in developing analogs with fewer undesirable side effects. 3,5- diiodothyropropionic acid (DITPA) has been shown to improve diastolic function in both animal models and a recently completed double-blind placebo controlled trial in 19 humans. The goal of the proposed Phase II study is to show safety and demonstrate a medication of efficacy of DITPA needed in patients with CHF. This study is a prerequisite for a larger Phase III trial which would determine whether mortality is improved with DITPA. To better define the appropriate doses, prior to the Phase II study we will conduct an initial pharmacokinetic study.
NCT00663936
The primary objective of the study is to evaluate the efficacy of T-817MA in AD patients to treat dementia. Efficacy will be cognitive function, as measured by the ADAS-cog cognitive assessment. The secondary objectives of the study are to evaluate the safety of T-817MA and the activities of daily living (assessed with the ADCS-ADL) of AD patients taking T-817MA, and to evaluate the efficacy of T-817MA in AD patients with an overall global assessment using the ADCS-CGIC.
NCT01050257
This partially randomized, multi-center parallel-group study will evaluate the safety, pharmacokinetics and the effect on viral load and viral shedding of Tamiflu (Oseltamivir) in patients with influenza. Adult and adolescent patients will be randomized to receive either 100 mg or 200 mg of study drug intravenously every 12 hours. Investigators and patients are blinded to knowledge of the assigned dose of Tamiflu. There is an option to convert to oral Tamiflu after 6 intravenous infusions. The anticipated time on study treatment is 5 days, with an optional treatment extension of a further 5 days, if necessary. There will be a non-randomized, open-label treatment group for patients with moderate/severe renal impairment or renal failure. Intravenous dose levels and frequency will be adjusted appropriately to their renal situation.
NCT00800735
This single arm study will provide treatment or re-treatment with PEGASYS as monotherapy or in combination with ribavirin (Copegus), to patients with chronic hepatitis C (CHC) who have participated in a previous Roche or Roche partner protocol where access to treatment or re-treatment was promised or deemed appropriate following completion of the original protocol ('donor' protocol). Patients who qualify for treatment or re-treatment will begin PEGASYS monotherapy, at a maximum dose of 180 µg weekly, or combination therapy with Copegus, 800-1200 mg daily, as continuation of treatment after the wash-out period defined in their donor protocol. PEGASYS treatment is not to exceed the approved treatment duration of 48 weeks in genotype G1 with a treatment-free follow up period of 24 weeks.
NCT00240435
The primary objective was to compare the bronchodilator efficacy of two doses (5 mcg and 10 mcg) of tiotropium inhalation solution delivered by the Respimat inhaler once daily to placebo and to ipratropium bromide MDI four times daily in patients with COPD. The secondary objective was to compare the safety of tiotropium inhalation solution delivered by the Respimat to placebo and ipratropium bromide MDI.
NCT00007969
RATIONALE: Photodynamic therapy uses light and drugs that make cancer cells more sensitive to light to kill tumor cells. Photodynamic therapy may be effective in treating melanoma. PURPOSE: Phase I/II trial to study the effectiveness of photodynamic therapy in treating patients who have stage III or stage IV melanoma.
NCT01469065
This will be a 2-week oral dose study of PF 04991532, performed in patients with type 2 diabetes. Safety, pharmacokinetics (how the drug is distributed in the body), and pharmacodynamics (how the drug works in the body) will be studied. Patients may be asked to wash off their diabetes medication for 4-6 prior to study drug administration, and they will remain in the clinical research unit for a total of 20 days for baseline tests, 2 weeks of dosing, and some follow up tests.
