NCT ID: NCT00606788 Suspended - Clinical trials for Cardiovascular Diseases

Therapy Study of Automated Protocolized vs. Physician-Directed Non-Protocolized Weaning

Start date: November 2005
Phase: N/A
Study type: Interventional

The purpose of this study was to determine whether computer-driven protocolized weaning is superior to physician-directed non-protocolized weaning in over-24-hours-ventilated surgical intensive care unit (ICU) patients. The main hypothesis was that weaning duration differs between both methods. Secondary hypotheses were that reintubation rate, duration of mechanical ventilation, intensive care unit (ICU) length of stay and workload for physicians and nurses differ between both methods.

NCT ID: NCT00593762 Suspended - Clinical trials for Peripheral Arterial Occlusive Disease

ASA- and Clopidogrel-Responsiveness in Patients With Peripheral Arterial Occlusive Disease and Interventional Procedures

Start date: May 2005
Phase: N/A
Study type: Observational

The purpose of the study is to determine the response to aspirin (ASA) and Clopidogrel in patients with peripheral arterial occlusive disease (PAOD) requiring interventional procedures and to investigate if patients with "resistance" to ASA or Clopidogrel have an unfavourable outcome during long-term follow-up

NCT ID: NCT00529945 Suspended - Stroke Clinical Trials

PFx Closure System in Subjects With Cryptogenic Stroke, TIA, Migraine or Decompression Illness

Paradigm IV
Start date: August 2007
Phase: N/A
Study type: Interventional

The primary object of this study is to demonstrate the continued safety and performance of the PFx Closure System when utilized for patients with PFOs suffering from cryptogenic stroke, transient ischemic attack, migraine or decompression illness.

NCT ID: NCT00515970 Suspended - Clinical trials for Carcinoma, Basal Cell

Curettage Versus Excision in Nodular and Superficial Basal Cell Carcinomas

Start date: December 2007
Phase: N/A
Study type: Interventional

Basal cell carcinoma (BCC) is the most frequent skin cancer. Uncontrolled growth destroys local anatomic structures. There are various treatment alternatives with different recurrence rates and expenses. After surgical excision, the recurrence rate is in between 3 and 4% and the procedure is relatively expensive. Photodynamic therapy as well as imiquimod 5% are expensive therapies with high recurrence rates, that lack histologic evidence of BCC. Cryosurgery and curettage are inexpensive, although the recurrence rates are higher than after surgical excision. This prospective, randomized trial compares recurrence rates, cosmetic outcome, and surgery-related complications after curettage versus surgical excision in nodular and superficial BCC. About 600 tumors will be included. One half is treated by curettage, the other half by surgical excision. The follow-up period is four years. If the difference between recurrence rates is ≤7% and the cosmetic outcome as well as the surgery-related complications are not worse after curettage, surgical excision must be considered an overtreatment.

NCT ID: NCT00460967 Suspended - Clinical trials for Age-Related Maculopathy

Safety and Effectiveness Investigation for Dry, Non-Exudative Age Related Macular Degeneration (AMD) Using Rheopheresis

RHEO-AMD
Start date: January 2007
Phase: Phase 3
Study type: Interventional

SUMMARY Age-related macular degeneration (AMD) is the leading cause of late onset visual impairment and legal blindness in people 65 years of age or older in the United States. It is a heterogeneous clinical entity in which retinal degeneration occurs predominantly in the macula in the context of aging and leads to impairment primarily of central visual acuity. The degenerative retinal eye disease occurs in two forms - a non-exudative "dry" form and an exudative "wet" form which in an individual patient may also represent stages of the disease. Non-exudative AMD accounts for 80-90% of AMD cases and it involves a constellation of clinical features that can include drusen, pigment clumping and/or retinal pigment epithelium (RPE) dropout, and geographic atrophy. Because of the overwhelming numbers of "dry" AMD subjects, the cumulative impact of this vision loss is significant. There is no effective therapy for maintaining or improving vision associated with dry AMD. The only therapy for persons with dry AMD is an oral supplement containing high doses of antioxidants and zinc, which was tested by the National Eye Institute in a large, multi-center, double-masked, sham-controlled clinical trial1. This antioxidant therapy was shown to modestly retard the progression of dry AMD from an intermediate stage to the advanced stages and confirmed the benefit of antioxidant therapy in this disease. There is currently no FDA-approved therapy for the treatment of subjects with dry AMD. Recently, the MIRA-1 modified per protocol population showed the effectiveness of Rheopheresis which is an application of selective therapeutic apheresis, namely double filtration plasmapheresis (DFPP) using a specifically designed filter for plasma filtration in subjects with non-exudative AMD. At one year the study reported with statistical significance (1) approximately a one line vision improvement in the Rheopheresis group versus no change in the Sham group and (2) 28% of subjects randomized to the active treatment gaining at least one line vision versus only 9% of subjects randomized to the sham treatment. With a total of 300 subjects with dry AMD and visual acuity of 20/40-20/100 inclusive, the current investigation plans to prove the effectiveness of the Rheopheresis treatment on a larger scale. Each subject will receive a series of 8 treatments (either active treatment or sham treatment in a 2:1 ratio) for a period of approximately 2.5 months. In addition, a post-treatment ophthalmic evaluation will be performed 2 weeks after the 8th treatment (approximately 3 months after the baseline visit) and at the 6, 9 and 12 month visits. Comparing the one-year proportions of at least a 10-letter gain in ETDRS LogMar BCVA from baseline, the current investigation will show the effectiveness of Rheopheresis treatment (compared to sham treatment) for treating dry AMD subjects. Other secondary effectiveness endpoints, including mean changes and proportions of BCVA better than 20/40 at one year, will be analyzed to support the main investigation.

NCT ID: NCT00335296 Suspended - Clinical trials for Patent Foramen Ovale

PFx Closure System in Subjects With Cryptogenic Stroke,Transient Ischemic Attack,Migraine or Decompression Illness(PFO)

Start date: May 2006
Phase: N/A
Study type: Interventional

The primary objective of this study is to demonstrate the safety and performance of the PFx Closure System when utilized for patients with PFOs suffering from cryptogenic stroke, transient ischemic attack, migraine or decompression illness.

NCT ID: NCT00102856 Suspended - Healthy Clinical Trials

Neuromodulation and Language Acquisition (Stage Ib)

Start date: January 2005
Phase: Phase 4
Study type: Interventional

The purpose of this study is to determine whether rivastigmine or pramipexol are effective in boosting semantic language acquisition in healthy subjects.

NCT ID: NCT00003980 Suspended - Clinical trials for Unspecified Adult Solid Tumor, Protocol Specific

BIBX 1382 in Treating Patients With Solid Tumors

Start date: February 1999
Phase: Phase 1
Study type: Interventional

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase I trial to study the effectiveness of BIBX 1382 in treating patients who have solid tumors.
