NCT ID: NCT01044875 Recruiting - Clinical trials for Proliferative Diabetic Retinopathy

Trial of Yellow 577 nm Laser Versus Green 532 nm Laser for Proliferative Diabetic Retinopathy

UMPDR
Start date: September 2009
Phase: N/A
Study type: Interventional

The purpose of this study is to measure effectiveness of yellow 577 nm laser compared to conventional green laser 532 nm for diabetic retinopathy in terms of number of treatment sessions required and visual acuity outcome. The study also compares pain score of patients receiving laser treatment and side effects of laser treatment.

NCT ID: NCT00700895 Recruiting - Clinical trials for Indications for Warfarin Therapy

Assessing the Clinical Benefits of a Pharmacogenetics-Guided Dosing Regiment for Calculating Warfarin Maintenance Dose

Start date: August 2006
Phase: Phase 3
Study type: Interventional

Interethnic differences in warfarin dose requirements in the Asian population have been well described. Our previous studies showed that warfarin maintenance doses in our multi-ethnic population were closely related to patient demographics and genetic polymorphisms in cytochrome(CYP)P4502C9 and vitamin K epoxide reductase complex subunit 1(VKORC1). A retrospective regression model combining these predictors accounts for 57.8% of the variability in warfarin dose.

NCT ID: NCT00358943 Recruiting - Gaucher Disease Clinical Trials

International Collaborative Gaucher Group (ICGG) Gaucher Disease Registry & Pregnancy Sub-registry

Start date: April 1, 1991
Phase:
Study type: Observational [Patient Registry]

The ICGG Gaucher Registry is an ongoing, international multi-center, strictly observational program that tracks the routine clinical outcomes for patients with Gaucher disease, irrespective of treatment status. No experimental intervention is involved; patients in the Registry undergo clinical assessments and receive care as determined by the patient's treating physician. The objectives of the Registry are: - To enhance understanding of the variability, progression, identification, and natural history of Gaucher disease, with the ultimate goal of better guiding and assessing therapeutic intervention. - To assist the Gaucher medical community with the development of recommendations for monitoring patients, and to provide reports on patient outcomes, to optimize patient care. - To characterize the Gaucher disease population. - To evaluate the long-term effectiveness of imiglucerase and of eliglustat. Gaucher Pregnancy Sub-registry: The primary objective of this Sub-registry is to track pregnancy outcomes, including complications and infant growth, in all women with Gaucher disease during pregnancy, regardless of whether they receive disease-specific therapy. No experimental intervention is given; thus a patient will undergo clinical assessments and receive standard of care treatment as determined by the patient's physician.If a patient consents to this Sub-registry, information about the patient's medical and obstetric history, pregnancy, and birth will be collected, and, if a patient consents to data collection for her infant, data on infant growth through month 36 postpartum will be collected.

NCT ID: NCT00271180 Recruiting - Heart Failure Clinical Trials

Product Performance Report: Evaluate Long-term Reliability & Performance of Medtronic Marketed Cardiac Therapy Products

PPR
Start date: January 1983
Phase:
Study type: Observational

The main purpose of the Product Performance Report (formerly referred to as System Longevity Study) is to evaluate long-term performance of Medtronic market-released cardiac rhythm products by analyzing product survival probabilities.

NCT ID: NCT00231400 Recruiting - Pompe Disease Clinical Trials

Pompe Disease Registry Protocol

Start date: September 15, 2004
Phase:
Study type: Observational [Patient Registry]

The Pompe Registry is a global, multicenter, international, longitudinal, observational, and voluntary program for patients with Pompe disease, designed to track the disease's natural history and outcomes in patients, both treated and not. Data from the Registry are also used to fulfill various global regulatory commitments, to support product development/reimbursement, and for other research and non-research related purposes. The objectives of the Registry are: - To enhance understanding of the variability, progression, identification, and natural history of Pompe disease, with the ultimate goal of better guiding and assessing therapeutic intervention. - To assist the Pompe medical community with the development of recommendations for monitoring patients, and to provide reports on patient outcomes, to optimize patient care. - To characterize the Pompe disease population. - To evaluate the long-term effectiveness of alglucosidase alfa.

NCT ID: NCT00196742 Recruiting - Fabry Disease Clinical Trials

Fabry Disease Registry & Pregnancy Sub-registry

Start date: July 31, 2001
Phase:
Study type: Observational [Patient Registry]

The Fabry Registry is an ongoing, international multi-center, strictly observational program that tracks the routine clinical outcomes for patients with Fabry disease, irrespective of treatment status. No experimental intervention is involved; patients in the Registry undergo clinical assessments and receive care as determined by the patient's treating physician. The primary objectives of the Registry are: - To enhance the understanding of the variability, progression, and natural history of Fabry disease, including heterozygous females with the disease; - To assist the Fabry medical community with the development of recommendations for monitoring patients and reports on patient outcomes to help optimize patient care; - To characterize and describe the Fabry population as a whole; - To evaluate the long-term safety and effectiveness of Fabrazyme® Fabry Pregnancy Sub-registry: This Sub-registry is a multicenter, international, longitudinal, observational, and voluntary program designed to track pregnancy outcomes for any pregnant woman enrolled in the Fabry Registry, regardless of whether she is receiving disease-specific therapy (such as enzyme replacement therapy with agalsidase beta) and irrespective of the commercial product with which she may be treated. Data from the Sub-registry are also used to fulfill various global regulatory requirements, to support product development/reimbursement, and for other research and non-research-related purposes. No experimental intervention is given; thus a patient will undergo clinical assessments and receive standard of care treatment as determined by the patient's physician. If a patient consents to this Sub-registry, information about the patient's medical and obstetric history, pregnancy, and birth will be collected, and, if a patient consents to data collection for her infant, data on infant growth through month 36 postpartum will be collected.

NCT ID: NCT00144794 Recruiting - Clinical trials for Mucopolysaccharidosis I (MPS I)

Mucopolysaccharidosis I (MPS I) Registry

Start date: November 20, 2003
Phase:
Study type: Observational

The Mucopolysaccharidosis I (MPS I) Registry is an ongoing, observational database that tracks the outcomes of patients with MPS I. The data collected by the MPS I Registry will provide information to better characterize the natural history and progression of MPS I as well as the clinical responses of patients receiving enzyme replacement therapy, such as Aldurazyme (Recombinant Human Alpha-L-Iduronidase), or other treatment modalities. The objectives of the Registry are: - To evaluate the long-term effectiveness and safety of Aldurazyme® (laronidase) - To characterize and describe the MPS I population as a whole, including the variability, progression, and natural history of MPS I - To help the MPS I medical community with the development of recommendations for monitoring patients and reports on patient outcomes to optimize patient care
