Phase II Randomized Trial of Arginine Butyrate Plus Standard Local Therapy in Patients With Refractory Sickle Cell Ulcers Clinical Trials Information presented on Clinical Trials Search isn't designed to be a substitute for certified healthcare advice, travels to or professional assistance using a genuine medical doctor. We are not physicians. Always confer with your dr. about Phase II Randomized Trial of Arginine Butyrate Plus Standard Local Therapy in Patients With Refractory Sickle Cell Ulcers conditions. Clinical Trials Search.org is a site devoted to listing clinical research studies in human subjects. Phase II Randomized Trial of Arginine Butyrate Plus Standard Local Therapy in Patients With Refractory Sickle Cell Ulcers Clinical research trials and Phase II Randomized Trial of Arginine Butyrate Plus Standard Local Therapy in Patients With Refractory Sickle Cell Ulcers medical trials happen in hundreds of places across the United States. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials usually measure the effectualness of new drugs. The intention of the studies / undertakings is to solve certain human healthcare questions. Clinical trials are a popular manner for mDs, government agencies, and private sector companies to locate treatments for all forms of circumstances, such as Phase II Randomized Trial of Arginine Butyrate Plus Standard Local Therapy in Patients With Refractory Sickle Cell Ulcers. Phase II Randomized Trial of Arginine Butyrate Plus Standard Local Therapy in Patients With Refractory Sickle Cell Ulcers Clinical Trials and other clinical trials allow for volunteers to undergo medical treatment choices before they are available to the general public. Some times the human subjects get treatment for free of charge, and sometimes they are paid for their time. Occasionally there is a cost for a Phase II Randomized Trial of Arginine Butyrate Plus Standard Local Therapy in Patients With Refractory Sickle Cell Ulcers clinical trial. Participants frequently get the best healthcare available for their Phase II Randomized Trial of Arginine Butyrate Plus Standard Local Therapy in Patients With Refractory Sickle Cell Ulcers condition. Risks are a reality, nonetheless, and can include extra or frequent physician trips, medical risks (possibly life-jeopardising), and/or the treatment being ineffective. Trials are federally governed with exacting guidelines to protect clinical trials subjects.

Phase II Randomized Trial of Arginine Butyrate Plus Standard Local Therapy in Patients With Refractory Sickle Cell Ulcers
For Condition: Sickle Cell Anemia,Skin Ulcers
Status: Recruiting
Sponsor(s): FDA Office of Orphan Products Development , Boston University School of Medicine
Synopsis: OBJECTIVES: I. Compare the efficacy of local care alone vs local care plus arginine butyrate in terms of healing rate in patients with refractory sickle cell ulcers. II. Determine the effect of arginine butyrate therapy on tissue factors related to promotion or inhibition of wound healing in these patients. III. Determine whether the regimen used in this study is appropriate for testing in pivotal trials.
Details: PROTOCOL OUTLINE: This is a randomized, multicenter study. Patients are randomized to one of two treatment arms. Arm I: Patients receive arginine butyrate IV over 6-9 hours at night 5 days a week for 12 weeks, plus concurrent standard local therapy consisting of cleaning, saline irrigation, and dressing changes as prescribed by each patient's physician. Patients who experience progressive healing receive arginine butyrate 3-4 times a week. Arginine butyrate treatment may be discontinued and reinstated following a single 2 week medical complication. Arm II: Patients receive standard local therapy only for 12 weeks. Patients randomized to arm II may cross over to receive arginine butyrate if no or less than 25% healing is observed after 12 weeks. Patients whose ulcers have closed by at least 15% per course may receive 2 additional 8-week courses of arginine butyrate therapy and are followed for 2 months after healing is completed.
