NCT00520143
Pompe disease (also known as glycogen storage disease Type II) is caused by a deficiency of a critical enzyme in the body called acid alpha-glucosidase (GAA). Normally, GAA is used by the body's cells to break down glycogen (a stored form of sugar) within specialized structures called lysosomes. In patients with Pompe disease, an excessive amount of glycogen accumulates and is stored in various tissues, especially heart and skeletal muscle, which prevents their normal function. The objective of this expanded access study is to provide patients with Pompe disease in the United States (US), access to alglucosidase alfa produced from a scaled up manufacturing process for a limited time until production at this scale is approved for commercial use by the Food and Drug Administration.
NCT00832507
This Phase 2, randomized, double-blind, placebo-controlled, multicenter, dose-ranging study will compare the efficacy, safety, and tolerability of cicletanine hydrochloride (HCl) to placebo in subjects with PAH. Study drug will be administered alone, or on the background of stable PAH therapy. The study will consist of 3 periods: a screening period, a 12-week placebo-controlled treatment period, and a long-term, blinded extension period.
NCT00458679
We would like patients to be in a research study to determine the safety and effectiveness of special cells that may make their own immune system fight their cancer. To do this, we will put a special gene into cancer cells that have been taken from the patients body. This will be done in the laboratory. This gene will make the cells produce interleukin 2 (IL-2), which is a natural substance that may help their immune system kill cancer cells. Additionally, we will stimulate the cancer cells with normal embryonic fibroblasts (cells that develop into normal connective tissues in the body) so that they will make another natural protein called CD40 ligand (CD40L). Studies of cancers in animals suggest IL-2 performs better when mixed with CD40L. Some of these cells will then be put back into the patients body with the goal that they will act like a vaccine and stimulate their immune system to attack the CLL cells. Studies of cancers in animals and in cancer cells that are grown in laboratories suggest that combining substances like IL-2 and CD40L with cancer cells help the body recognize and kill cancer cells. We have already conducted a study similar to this in patients with CLL. In that study, the subjects received about three months of injections (shots). In those subjects we saw some changes in the subject's immune system that might indicate that the modified cells were helping their immune system fight the cancer. However, in most of the subjects this change in the immune system went away after the injections were stopped. In this study we want to see if we can make the change in the immune system last longer by giving more injections over a longer period of time. We hope that this might produce a better response directed at the CLL cells. We will also be looking at the effect on cells called cancer stem cells which grow into the CLL cells we see in the blood. Specifically, this study will allow subjects to receive the injections for up to one year.

NCT01462435
The purpose of this study is to determine whether Diclofenac \[Test\] Capsules are safe and effective for the treatment of bunionectomy pain.
NCT01364922
The primary purpose of this study was to evaluate the analgesic effect and safety of hydrocodone/acetaminophen extended release compared to placebo.
NCT00874796
This is a Phase 2b, randomized, double-blind, parallel-group, placebo-controlled, multicenter study investigating the safety, tolerability and efficacy of two oral doses of GS-9450 in adults with chronic Hepatitis C Virus (HCV). Approximately 240 subjects 18-65 years of age who meet study entry criteria will be randomized (in other words, selected at random, like flipping a coin) to one of three treatment groups (80 subjects per treatment group) as follows:GS-9450 10 mg once daily,GS-9450 40 mg once daily, or matching placebo once daily. Following randomization, subjects will return within seven business days for a Baseline (Day 1) visit, at which time study medication will be dispensed and subjects will enter a 26 week treatment phase. During the treatment phase, subjects will receive study drug once daily for 24 weeks and then taper off of study drug over the following 2 weeks by receiving study drug once every other day for one week and then every 3 days for one week. Following completion of the treatment phase, subjects will enter a 4-week off-treatment follow-up phase.
NCT01658618
This observations safety study is intended for subject who participated in the 802-247-09-029 study with the investigational product HP802-247 for venous leg ulcers and received at least one application of HP802-247 or Vehicle (an inactive substance). This study is being done for the following purposes: 1. to identify new adverse events, 2. to examine ongoing adverse events not resolved in subjects who participated in the 802-247-09-029 trial, 3. to record wound status, and 4. to determine if there are differences in Health Related Quality of Life (HRQoL) associated with the treatment assignment from the 802-247-09-029 Trial. Investigational means that HP802-247 has not been approved by the U.S. Food and Drug Administration (FDA).

NCT00389207
Primary purpose of this study is to compare the efficacy and safety of two different nevirapine (Viramune) dosing regimens (once daily (QD) and twice daily (BID) application) and of atazanavir/ritonavir (Reyataz/Norvir), all on an emtricitabine/tenofovir disoproxil fumarate (DF) (Truvada) background. Patients will receive either nevirapine (NVP) 200 mg twice daily, or NVP 400 mg once daily , or ritonavir-boosted atazanavir (ATZ/r), all in combination with emtricitabine (FTC) and tenofovir DF (TDF). All patients receiving NVP will start at 200 mg once daily for 2 weeks, because it has been demonstrated that this lead-in dosing regimen reduces the frequency of NVP-induced rash. At Visit 3 (Week 2), patients increase the NVP dose to either 200 mg twice daily or to 400 mg once daily. Patients receiving ATZ/r will be treated with ATZ 300 mg once daily, boosted by 100 mg ritonavir (RTV) once daily. Background antiretroviral therapy for all patients consists of one tablet of Truvada. Treatment duration is 48 weeks (primary endpoint) with an extension to 144 weeks. Patients may also participate in the metabolic sub-study, comparing NVP and ATZ/r for signs and symptoms of lipodystrophy and serum lipid/glycaemic abnormalities.
NCT01306630
This is an open-label, multi-center, dose-finding study of tivozanib administered in combination with capecitabine. During the dose-escalation portion, sequential cohorts of subjects with advanced solid tumors will be enrolled in order to establish the maximum tolerated dose (MTD). If the MTD is not reached, the recommended Phase 2 dose (RP2D) will be determined. In the expansion cohort, subjects with locally advanced or metastatic breast or colon cancer will be enrolled at MTD (or RP2D) to further evaluate safety and activity of this combination in these tumor types.
NCT00763932

NCT01084005
The objective of the current study is to investigate the efficacy, safety and tolerability of linagliptin (5 mg / once daily) compared to placebo given for 24 weeks as add-on therapy to stable treatment in elderly patients with T2DM with insufficient glycaemic control
