NCT ID: NCT00237263 Completed - Parkinson's Disease Clinical Trials

An Extension Study of Entacapone in Patients With Parkinson's Disease With End-of-dose Wearing-off. This Study is Not Recruiting in the United States

Start date: February 2003
Phase: Phase 2
Study type: Interventional

The purpose of this study is to evaluate the safety and efficacy of the long-term treatment of entacapone in patients with Parkinson's disease with end-of-dose wearing-off. This study is not recruiting patients in the United States.

NCT ID: NCT00234676 Completed - Parkinson's Disease Clinical Trials

POETRY: Study of Estrogen Replacement Therapy in Postmenopausal Women With Parkinson's Disease

Start date: October 2003
Phase: Phase 2
Study type: Interventional

The primary objectives of the POETRY study are to assess the safety and tolerability of estrogen replacement therapy (ERT) in postmenopausal women with Parkinson's disease (PD) and to assess recruitment for a study of ERT in postmenopausal women with PD.

NCT ID: NCT00234364 Completed - Parkinson's Disease Clinical Trials

Pergolide Treatment and Valvular Heart Disease

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

In a blinded echocardiographic study we investigate the frequency of valvular abnormalities in a group of Parkinson patients treated with either ergot derived dopamine agonists (pergolide and cabergoline) or non-ergot derived dopamine agonists (pramipexole and ropinirole). The ability to detect patients with valvular abnormalities by clinical approach is examined.

NCT ID: NCT00229736 Completed - Parkinson's Disease Clinical Trials

A Study of AAV-hAADC-2 in Subjects With Parkinson's Disease

Start date: November 2004
Phase: Phase 1
Study type: Interventional

Safety Study in subjects with Parkinson's Disease

NCT ID: NCT00226460 Completed - Parkinson's Disease Clinical Trials

Phase 2, Double-blind, Randomized, Controlled Multi-center Clinical Trial of the Safety and Efficacy of Transplanted Fetal Porcine Cells in Patients With Parkinson's Disease.

Start date: August 1997
Phase: Phase 2
Study type: Interventional

The purpose of this study was to evaluate the differences in safety and efficacy between Parkinson's disease patients who either received transplantation of fetal porcine cells or placebo treatment.

NCT ID: NCT00224263 Completed - Parkinson's Disease Clinical Trials

Efficacy and Safety of Lingzhi in Patients With Early Parkinson's Disease

Start date: September 2005
Phase: Phase 2
Study type: Interventional

The purpose of this study is to determine whether Lingzhi (Ganoderma), a widely used traditional Chinese Medicine is effective and safe in the treatment of Parkinson's disease when combined use with L-dopa.

NCT ID: NCT00215904 Completed - Parkinson's Disease Clinical Trials

D-serine Adjuvant Treatment for Parkinson's Disease

Start date: August 2003
Phase: Phase 4
Study type: Interventional

The proposed experiment will evaluate the effects of the NMDA receptor full agonist D-serine (~2g/day) on persistent symptoms of Parkinson's Disease and on antiparkinsonian drugs-induced dyskinesias. D-serine will be used as add-on therapy to on-going medications received by Parkinson's Disease patients. The rational for this study stems from observations made in pervious clinical trials with schizophrenia patients, in which it was demonstrated that D-serine adjuvant treatment resulted in:1)improvement of parkinsonian side effects induced by antipsychotic drugs and 2) improvement of depression and negative (i.e apathy, blunted effects, anhedonia) symptoms which are similar to symptoms encountered in Parkinson's Disease. The study will have a crossover design in accordance to which each patient will receive, in random order D-serine and placebo for a 6 weeks period each. Thus, any participant will have the opportunity to receive the experimental treatment.

NCT ID: NCT00212693 Completed - Parkinson's Disease Clinical Trials

Controlled Study of ONO-2506PO in Patients With Parkinson's Disease in Japan

Start date: January 2004
Phase: Phase 2
Study type: Interventional

The purpose of this study is to evaluate the efficacy and safety of ONO-2506PO in patients with Parkinson's Disease

NCT ID: NCT00209508 Completed - Parkinson's Disease Clinical Trials

2 Year Study to Evaluate the Effects of GPI 1485 on [123I]b-CIT/SPECTScanning and Clinical Efficacy in Patients With PD

Start date: November 2002
Phase: Phase 2
Study type: Interventional

This study was designed to assess whether GPI 1485 has the ability to delay or stop disease progression and improve symptoms in patients with Parkinson's disease (PD) that is already being treated with a dopamine agonist therapy. Whether the drug is working will be assessed by evaluating clinical endpoints such as UPDRS scores and by evaluating images, obtained by SPECT scan, of brain activity. Participants in the study will be given either placebo or GPI 1485 treatment. The duration of the study is 2-years and patients are required to complete 12 safety visits and 3 SPECT scans. SPECT scans will be taken before, after 1-year, and after 2-years of treatment with GPI 1485. In completing the SPECT scan, patients will be injected with a radioactive investigational drug b-CIT and pictures taken using a Single Photon Emission Computed Tomography (SPECT) camera.

NCT ID: NCT00203957 Completed - Parkinson's Disease Clinical Trials

Study of KW-6002 (Istradefylline) in Parkinson's Disease in Patients With Motor Response Complications on Levodopa

Start date: March 2005
Phase: Phase 3
Study type: Interventional

The purpose of this study is to confirm the long term tolerability and safety of oral 20 or 40 mg/d doses of Istradefylline.
