All Clinical Trials for Buphenyl
| Trial ID | Title | Status | Sponsor | Phase | Start Date | Summary |
|---|---|---|---|---|---|---|
| NCT00002796 ↗ | Phase I-II Study of Fluorouracil in Combination With Phenylbutyrate in Advanced Colorectal Cancer | Terminated | National Cancer Institute (NCI) | Phase 1/Phase 2 | 1997-05-01 | Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Interferon-gamma may interfere with the growth of tumor cells and slow the growth of the tumor. Combining more than one drug with interferon-gamma may kill more tumor cells. This phase I/II trial is studying the side effects and best dose of giving fluorouracil together with phenylbutyrate, indomethacin, and interferon-gamma and to see how well it works in treating patients with stage IV colorectal cancer |
| NCT00345605 ↗ | Arginine and Buphenyl in Patients With Argininosuccinic Aciduria (ASA), a Urea Cycle Disorder | Completed | Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) | Phase 2 | 2008-02-01 | Urea cycle disorders are inherited illnesses in which the body does not produce enough of the chemicals that remove ammonia, a byproduct of protein metabolism, from the blood stream. Elevated ammonia levels can lead to brain damage and death. Argininosuccinic aciduria (ASA) is a type of urea cycle disorder that is characterized specifically by high levels of argininosuccinic acid, a chemical involved in the urea cycle. People with ASA are at risk for serious liver damage, which may be due to the elevated levels of argininosuccinic acid. Sodium phenylbutyrate (Buphenyl-TM) is a drug that has been used to treat other types of urea cycle disorders. This study will evaluate whether Buphenyl-TM in conjunction with decreased arginine dose (in addition to a normal regimen of protein) will improve short-term liver function and decrease plasma citrulline and ASA levels in people with ASA. |

| NCT00533559 ↗ | Mechanism of Fatty Acid-induced Impairment of Glucose-simulated Insulin Secretion - Effect of Buphenyl | Completed | University Health Network, Toronto | Phase 4 | 2007-09-01 | An increase of plasma free fatty acids impairs insulin secretion and insulin sensitivity, thereby playing an important role in causing type 2 diabetes. Lipotoxicity plays an important role in the progression from normal glucose tolerance to fasting hyperglycemia and coversion to frank type 2 diabetes. A recent publication in the journal Science showed that buphenyl, when given to obese diabetic mice, resulted in normalization of hyperglycemia, restoration of systemic insulin sensitivity, resolution of fatty liver disease and inhancement of insulin action in liver, muscle and adipose tissue. the mechanism of action is believed to be due to reduction of endoplasmic reticulum (ER) stress. Buphenyl is currently approved for the treatment of rare inherited disorders of the urea cycle. We plan to administer Buphenyl orally to humans at a dose far lower than that used for the treatment of urea cycle disorders for 2 weeks prior to the testing of pancreatic function. One potential mechanism whereby chromically elevated plasma FFAs and glucose impairment beta cell function and insuln sensitivity is by ER stress and this can be prevented by administeration of buphenyl. |
