Trial Type Trial ID Title Status Sponsor Phase Start Date Summary
New Indication NCT00090272 ↗ A Single Dose of a Marketed Drug Being Studied for a New Indication to Treat Surgical Site Infection Following Colorectal Surgery as Compared to a Marketed Drug Approved for This Indication (0826-039) Completed Merck Sharp & Dohme Corp. Phase 3 2002-04-01 The objective of this study is to evaluate the safety and efficacy of a one time dose of an intravenous marketed drug being evaluated for a new indication as compared to a marketed drug already approved for the prevention of surgical site infection following colorectal surgery.
New Formulation NCT00244777 ↗ Introduction of Hypo-osmolar ORS for Routine Use Completed United States Agency for International Development (USAID) Phase 4 2002-12-01 The World Health Organization has very recently recommended the routine use of a hypo-osmolar ORS in the management of diarrhoeal diseases. This recommendation is based on the better efficacy of the hypo-osmolar ORS over the standard WHO ORS demonstrated in controlled clinical trials. The recommendation, however, also expressed the need for "careful monitoring to better assess risk, if any, of symptomatic hyponatraemia". There thus is a need for phase IV trials before the new solution is introduced into routine clinical practice to assess the risk in relatively large number of patient populations. The proposed study will be carried out at two different settings- at the urban settings of the Dhaka Hospital (60000 patients) and at the rural settings of the Matlab Hospital (15000 patients) of ICDDR,B. The hypo-osmolar rice or glucose-based ORS will be introduced as standard management of patients with diarrhoea . The hypo-osmolar ORS will contain 75 mmol /L of sodium instead of 90 mmol/L. Surveillance will be carried out to detect adverse events focusing on the occurrence of seizures or undue lethargy during hospitalization. Each episode of seizure or undue lethargy would be evaluated to determine if they are associated with abnormal levels of serum sodium or glucose, or fever. It has been estimated that about 3% (1,800) of patients initially admitted to the Short Stay Ward of the Dhaka Hospital, and 340 patients at the Matlab Hospital might require admission to the longer stay inpatient wards due to seizure or altered consciousness. Such patients would be thoroughly assessed including determination of their serum sodium and glucose, two common causes of seizures/altered consciousness, to determine if and to what extent they could be attributed to hyponatraemia.The results from this study would be used in planning and implementing the routine use of the new formulation of ORS at all Government, NGO and private health care facilities that treat diarrhoeal patients, in Bangladesh and in other countries.
New Formulation NCT00244777 ↗ Introduction of Hypo-osmolar ORS for Routine Use Completed International Centre for Diarrhoeal Disease Research, Bangladesh Phase 4 2002-12-01 The World Health Organization has very recently recommended the routine use of a hypo-osmolar ORS in the management of diarrhoeal diseases. This recommendation is based on the better efficacy of the hypo-osmolar ORS over the standard WHO ORS demonstrated in controlled clinical trials.

OTC NCT00262145 ↗ Ability of a Tea Leaf Extracts Preparation to Slow Down Carbohydrate and Fat Absorption Completed NatureGen Phase 1 2005-10-01 Objective - A variety of herbal, over-the-counter preparations of tea leaves are said to reduce the rate of absorption of fat ( allegedly via inhibition of pancreatic lipase) and carbohydrate (via inhibition of carbohydrate digestion and blocking of glucose transport by the intestinal mucosa). There has been some study of the ability of these products to reduce the blood glucose increase observed after a carbohydrate meal and to reduce blood cholesterol levels in chronic studies. The purpose of the present study is to objectively determine if one cup of "tea" made from a combination of three types of tea leaves (mulberry, black and green tea) can cause malabsorption of carbohydrate and fat taken in conjunction with the tea. Research Design - The study will consist of a double blind, placebo controlled crossover study in 20 healthy subjects. On one of two days (one week apart) the subjects will ingest a standard meal consisting of 30 g of sucrose (in the tea) and 30 g of starch in the form of white rice plus 10 g of fat as butter. To measure triglyceride absorption, each meal will also contain 250 mg of 13-C labeled triolein. Triolein is a commonly ingested fat consisting of glycerol bound to three oleic acids. 13-C is a stable (non-radioactive) isotope of carbon. On one of the test days the subjects (randomly) will concurrently consume the active preparation, a tea containing extracts of the three types of tea leave described above plus the meal, and on the other test day they will consume the meal with a liquid placebo preparation (warm water, sugar and food coloring). Subjects will provide a breath sample before and at hourly intervals for 8 hours after ingestion of the meal. Carbohydrate malabsorption will be determined by the hydrogen concentration in the breath samples and fat malabsorption by the concentration of 13-CO2 in the breath samples. Clinical Significance - An increase in breath hydrogen indicates carbohydrate malabsoption and a low 13-CO2 indicates lipid malabsorption. Objective evidence that the tea leaf extract actually induces carbohydrate and/or fat malabsorption could provide the basis for further studies.
New Formulation NCT00490932 ↗ New Hypo-Osmolar ORS (Recommended by WHO) for Routine Use in the Diarrhea Management- Surveillance Study for Adverse Effects Completed Society for Applied Studies Phase 4 2005-03-01 For more than 25 years WHO and UNICEF have recommended a single formulation of glucose-based Oral Rehydration Salts (ORS) to prevent or treat dehydration from diarrhoea irrespective of the cause or age group affected. This product has proven effective and contributed substantially to the dramatic global reduction in mortality from diarrhoeal disease during the period. Based on more than two decades of research and recommendations by an expert group, WHO and UNICEF reviewed the effectiveness of a new ORS formula with reduced concentration of glucose and salts. Because of the improved effectiveness of this new ORS solution WHO and UNICEF recommended that countries use and manufacture this new formulation in place of the old one. While recommending this new ORS the experts also recommended that further monitoring is desirable to better assess the risk, if any of symptomatic hyponatraemia (low blood level of sodium salt). This is a surveillance study to evaluate adverse effect of routinely using the new ORS in a hospital admitting over 20,000 patients with diarrhea of all ages including cholera. If the new ORS is found safe, it will provide added confidence in its global use.
OTC NCT00610480 ↗ Tear Film Stability After Instillation of Over-the-Counter (OTC) Artificial Drops Completed Investigator initiated study N/A 2007-11-01 The goal of this research is to evaluate and compare the effectiveness of Systane® versus Optive™ on aqueous tear film stability in patients with a diagnosis of Dry Eye Syndrome and to determine the possible application for this product in the future. Systane® is marketed as over-the-counter tear lubricating therapy in the United States under the FDA monograph.

NCT00000115 ↗ Randomized Trial of Acetazolamide for Uveitis-Associated Cystoid Macular Edema Completed National Eye Institute (NEI) Phase 2 1990-12-01 To test the efficacy of acetazolamide for the treatment of uveitis-associated cystoid macular edema.
NCT00000412 ↗ Osteoporosis Prevention After Heart Transplant Completed Merck Sharp & Dohme Corp. Phase 3 1997-09-01 During the first year after a heart transplant, people often rapidly lose bone from their spine and hips. About 35 percent of people who receive heart transplants will suffer broken bones during the first year after transplantation. This study will compare the safety and effectiveness of the drug alendronate (Fosamax) and the active form of vitamin D (calcitriol) in preventing bone loss at the spine and hip after a heart transplant. In this study, people who have had a successful heart transplant will receive either active alendronate and a "dummy pill" instead of calcitriol, or active calcitriol and a dummy pill instead of alendronate for the first year after their transplant, starting within 1 month after transplant surgery. We will measure bone density in the hip and spine at the start of the study and after 6 and 12 months, and will also check for broken bones in the spine. This research should lead to ways of preventing this crippling form of osteoporosis.
