NCT00645268
To determine the effect on erectile function in a population of type 2 diabetic men with erectile dysfunction who have undergone the following treatment regimen: pre-treatment with a daily dose of double-blind sildenafil versus placebo for 4 weeks (Phase I) followed by an as-needed, flexible-dose, open-label treatment phase with sildenafil for 12 weeks (Phase II). To assess safety and tolerability of this dosing regimen and to investigate its effects on endothelial function and subject's responses to the Self-Esteem And Relationship (SEAR) questionnaire.
NCT00137072
Safety/Efficacy of 100-mg Viagra at 8 hours post dose in men with mild to moderate erectile dysfunction
NCT03466099
This is a clinical study where patients with diabetes and a vision threatening eye condition called "Diabetic Macular Edema" receive four injections into the eye at monthly intervals. The patients will already have tried the standard of care without complete success. The patients will be randomized to receive either a high dose, a low dose or a sham control treatment. The study will evaluate whether the new treatment improves vision and whether it changes the underlying course of the disease in the eye.
NCT01701362
This study is designed to investigate if pregabalin is effective in treating neuropathic (nerve) pain resulting from peripheral nerve trauma due to a traumatic or surgical event such as, for example, motor vehicle accident, fall, sports injury, knee or hip replacement, hernia repair, thoracotomy, mastectomy, focal/localized burns or crush injury.
NCT00632385
To assess the efficacy and safety of eletriptan for migraine headaches in subjects who were not satisfied with rizatriptan therapy
NCT00143481
The purpose of the study is to assess the impact of treatment with tolterodine ER versus placebo on Urgency Urinary Incontinence in sexually active women with OAB symptoms.
NCT00147654
The primary objective of the trial is to evaluate the effect of tolterodine ER plus tamsulosin versus placebo on patient perception of overall treatment benefit in men who have frequency and urgency, with or without urinary urge incontinence (UUI), with or without bladder outlet obstruction (BOO).
NCT02381457
This multi-center prospective observational study is designed to track birth outcomes and perinatal correlates to the Panorama prenatal screening test in the general population among ten thousand women who present clinically and elect Panorama microdeletion and aneuploidy screening as part of their routine care. The primary objective is to evaluate the performance of Single Nucleotide Polymorphism (SNP)-based Non Invasive Prenatal Testing (NIPT) for 22q11.2 microdeletion (DiGeorge syndrome) in this large cohort of pregnant women. This will be done by performing a review of perinatal medical records and obtaining biospecimens after birth to perform genetic diagnostic testing for 22q11.2 deletion. Results from the follow-up specimens will be compared to those obtained by the Panorama screening test to determine test performance. Specific test performance parameters will include: PPV, specificity, and sensitivity.
NCT03239873
This study will evaluate the immunogenicity, safety, and tolerability of VARIVAX® (Varicella Virus Vaccine Live) manufactured with a new passage extension (PE34) process compared with the VARIVAX® 2016 commercial process. The primary hypotheses being tested are that antibody response rate and mean antibody titer induced at 6 weeks after a single vaccination by VARIVAX® PE34 Process are non-inferior to those induced by VARIVAX® 2016 commercial process, and that antibody response rate induced by VARIVAX® PE34 Process is acceptable.
NCT01049217
The purpose of this study is to evaluate the efficacy of pregabalin compared to placebo in reducing neuropathic pain associated with HIV neuropathy.
NCT02951195
This is a Phase 2, randomized, double blind, placebo and active-controlled, parallel group, multicenter study designed to evaluate the safety and tolerability of VX-152 in Triple Combination (TC) with tezacaftor (TEZ; VX-661) and ivacaftor (IVA; VX-770) in subjects with cystic fibrosis (CF) who are heterozygous for the F508del mutation and a minimal function (MF) CFTR mutation not likely to respond to TEZ and/or IVA therapy (F508del/MF), or who are homozygous for the F508del mutation of the CF transmembrane conductance regulator (CFTR) gene (F508del/F508del).
NCT03346070
The purpose of this trial is to evaluate the safety and efficacy of Sugammadex when administered according to actual body weight (ABW) as compared to ideal body weight (IBW) for the reversal of both moderate and deep neuromuscular blockade (NMB) induced by either Rocuronium or Vecuronium in morbidly obese participants. The primary hypothesis of this investigation is that, compared to obese participants dosed based on IBW, obese participants receiving Sugammadex according to ABW will demonstrate a faster time to recovery to a Train Of Four (TOF) ratio of ≥0.9 (i.e. faster NMB reversal), pooled across NMB depth and type of neuromuscular blocking agent (NMBA; Rocuronium or Vecuronium) administered.
NCT01622140
This is a prospective cohort study of persons tested for latent tuberculosis infection at either high risk for exposure to Mycobacterium tuberculosis or high risk for progression to tuberculosis disease. The study will assess the relative performance and cost of three diagnostic tests for latent tuberculosis infection (tuberculin skin test, QuantiFERON-TB Gold In-Tube, and T-SPOT.TB) and will examine the rates of positive results among the cohort. This study will also determine the risk and rate of progression to active TB disease, overall and by the results of the three tests.
NCT01912456
The aim of this study is to assess the efficacy of C1-esterase inhibitor in preventing hereditary angioedema attacks when it is administered under the skin of subjects with hereditary angioedema. The safety of C1-esterase inhibitor will also be assessed. Each subject will enter a run-in period of up to 8-weeks. Subjects who complete the run-in period and who are eligible will then enter the treatment phase which comprises two sequential treatment periods. In the treatment phase, subjects will be randomized to one of four arms consisting of treatment with low- or higher-volume C1-esterase inhibitor in one treatment period and treatment with low- or higher-volume placebo in the other treatment period. The study will measure the number of hereditary angioedema attacks that subjects experience while receiving each treatment.
NCT02137837
This randomized Phase III trial studies how well the combination of fulvestrant and everolimus together or the combination of anastrozole, fulvestrant and everolimus together, improve progression-free survival (PFS) versus fulvestrant alone.
NCT00280059
The purpose of this study is to assess whether Lyrica is a safe and effective treatment for partial epilepsy in comparison with an established treatment, Lamictal.
NCT00143234
The purpose of the study is to measure the effect of the amlodipine/atorvastatin combination pill in reducing both elevated blood pressure and cholesterol levels to levels suggested by guidelines
NCT00514605
Each year up to 22 million persons in the US are tested for HIV. Currently available "rapid" tests do not provide test results for at least 30 minutes from the collection of serum and plasma from the subject. Providing accurate test results in less than a minute would make it easier to make timely decisions about treatment and counselling. This study will compare results of an experimental rapid test to existing standards to determine if the test can reliably and accurately diagnose HIV in less than one minute.
NCT01145417
This study examines the safety of pregabalin over a 6 month period in patients with neuropathic pain associated with HIV infection as an extension of another trial that tests the efficacy of pregabalin.
NCT03714152
This three-part, Phase 1 protocol will be the first clinical study of ABI-H2158. Parts 1 and 2 will be a Phase 1a, dose-ranging assessment of ABI-H2158 in healthy adult volunteers. If the dose-related safety, tolerability, and pharmacokinetics (PK) of ABI-H2158 in healthy volunteers are deemed satisfactory, then the study will advance to Part 3, a Phase 1b, dose-ranging assessment of ABI-H2158 in non-cirrhotic, CHB patients.
