New Formulation NCT01348243 ↗ Efficacy Of Clodronate 200 Mg/4 Ml I.M. Solution With 1% Lidocaine Every Other Week Vs Clodronate 100 Mg/3,3ml I.M. Solution With 1% Lidocaine Once-Week In A 1-Year Treatment Period Of Women With Postmenopausal Osteoporosis Completed Chiesi Farmaceutici S.p.A. Phase 3 2011-10-01 Clodronic acid 100 mg/3,3 ml is used to prevent and treat postmenopausal osteoporosis. The intramuscular formulation, which is given at a dose of 100 mg every 7 o 14 days, is at least as effective as daily oral therapy and appears more effective than intermittent intravenous treatment. Intramuscular clodronic acid in particular has also been associated with improvements in back pain. The drug is well tolerated, with no deleterious effects on bone mineralization, and use of parenteral therapy eliminates the risk of gastrointestinal adverse effects that may be seen in patients receiving oral bisphosphonates therapy. In order to simplify the therapeutic dosing regimen, reducing the number of administrations per month, and therefore increase adherence to bisphosphonates therapy of the patient, a new formulation of disodium clodronic acid containing 200 mg/4 mL for i.m. administration has been developed. Lidocaine in this new formulation, as local anaesthetic, is maintained at the same concentration as in the 100 mg clodronic acid formulation. The pharmacokinetics and tolerability of the intramuscular formulation of clodronic acid 200 mg in comparison to the marketed formulation clodronic acid 100 mg was evaluated in healthy post-menopausal volunteers. Two formulations were similar in terms of amount and rate of clodronic acid urinary excretion and in terms of safety profile.

NCT00001303 ↗ Effects of Endotoxin in Normal Human Volunteers Completed National Institutes of Health Clinical Center (CC) Phase 1 1992-04-06 Bacterial infections can progress to a life-threatening illness called septic shock, characterized by low blood pressure and vital organ damage. The syndrome is thought to be caused by parts of the bacteria and by the body s own immune response to the infection. A major bacterial product that interacts with the immune defenses is called endotoxin. This study will examine the body s response to endotoxin in the lungs or bloodstream. When endotoxin is given in small amounts to humans, even though it is not an infection, it triggers a set of responses that are typical of what one would see with a true bacterial infection. This allows us to study the earliest changes in molecules and cells that are involved in some bacterial infections. This type of model is safe and has been used in humans for many years to understand the body s responses during infections. Normal volunteers 18 to 45 years of age may be eligible for this study. Candidates will have a history and physical examination, blood and urine tests, electrocardiogram (EKG) and chest X-ray. In addition, volunteers 40 to 45 years old will have an exercise stress test to screen for asymptomatic coronary artery disease. Participants will undergo one or more of the following procedures: Bronchoscopy, Bronchoalveolar Lavage, Bronchial Brushings, and Endobronchial Mucosal Biopsies: These techniques for examining lung function are used routinely in patient care and clinical research. The mouth and nasal and lung airways are numbed with an anesthetic. A bronchoscope (pencil-thin flexible tube) is then passed through the nose into the large airways of the lung. Cells and secretions from the airways are rinsed with salt water (bronchoalveolar lavage) and a flexible brush the size of a pencil tip is passed through the bronchoscope to scrape cells lining the airways. Lastly, pieces of tissue (the size of the ball of a ballpoint pen) lining the airways are removed for examination under the microscope. Intravenous Endotoxin: A small dose of endotoxin is injected into a vein. Blood samples are drawn at regular intervals for 8 hours after the injection and again after 1, 2, 3, 7 and 14 days to analyze the body s immune response to the bacteria in the blood. Instilled Endotoxin in the Lungs: A small amount (2 teaspoons) of salt water is squirted through a bronchoscope into a lobe of one lung, and then salt water containing a small dose of endotoxin is squirted into the other lung. Bronchial lavage, brushing, and biopsy (see above) are then done to study the response of the lung to the endotoxin. In addition, air is withdrawn through the bronchoscope to study air components from the lung that was instilled with salt water or endotoxin. Nitric Oxide Therapy: Endotoxin is instilled in a lung (see above) and then nitric oxide a colorless, odorless, tasteless gas mixed with room air in a concentration of 40 parts per million, is given through a cushioned mask placed over the mouth and nose. (Some participants will be given the nitric oxide mixture and others will breathe only room air through the mask to test the effects of the nitric oxide on the lung inflammation.) The mask will be worn continuously for 6 hours and removed before repeat bronchoscopy with lavage, brushing and biopsy. Some of the above procedures require placement of a catheter (thin plastic tube) in a wrist artery to monitor blood pressure from heartbeat to heartbeat and to collect blood samples. First, the skin is numbed with an anesthetic (lidocaine). A needle is then inserted into the artery, the catheter is slipped over the needle into the vessel, and the needle is removed.
NCT00001524 ↗ Thalidomide to Treat Oral Lesions in HIV-Infected Patients Completed National Institute of Dental and Craniofacial Research (NIDCR) Phase 2 1996-06-01 This study will test the effectiveness of topical thalidomide in healing mouth sores in HIV infected patients. Oral (PO) thalidomide heals these sores at a dose of 200 mg per day. However, PO thalidomide can cause drowsiness, skin rashes, allergic reactions, increased viral load, and even nerve damage that may not be reversible. This study will evaluate the efficacy of a topical formulation of thalidomide (placed directly on the surface of the sore) for the healing of these sores. Persons with HIV infection of acquired immunodeficiency of at least 18 years of age with one or more chronic, painful intraoral lesions may be eligible for this study. Subjects must be referred by a primary care physician who is managing their care, and must have HIV/AIDS status confirmed. Patients' HIV treatment regimen will not be altered and those receiving highly active therapy will not be excluded. Patients will be excluded if they are concurrently being treated for mucosal lesions (including topical or systemic steroids, viscous lidocaine, topical or systemic anti-fungals, or mouthwashes), or concurrent thalidomide therapy; receving chemotherapy or radiation therapy for neoplasms; using concurrent acute therapy for opportunistic infections; concurrent use of sedatives (such as CNS depressants or alcohol use); history of allergy to thalidomide; pre-existing peripheral neuropathy of grade II or higher; pregnant or lactating females or those not practicing contraception according to FDA guidelines for thalidomide.
NCT00001724 ↗ Local Flurbiprofen to Treat Pain Following Wisdom Tooth Extraction Completed National Institute of Dental and Craniofacial Research (NIDCR) Phase 2 1997-11-01 This study will evaluate the effectiveness of the non-steroidal anti-inflammatory drug flurbiprofen (Ansaid® (Registered Trademark)) in relieving pain following oral surgery. Flurbiprofen is approved by the Food and Drug Administration for treatment of arthritis pain. Patients 16 years of age and older requiring third molar (wisdom tooth) extraction may be eligible for this study. Patients will undergo oral surgery to remove two lower third molar teeth. Before surgery, they will be given a local anesthetic (lidocaine with epinephrine) injected in the mouth and a sedative (Versed) infused through a catheter (thin plastic tube) placed in an arm vein. At the time of surgery, patients will also be given flurbiprofen or a placebo formulation (look-alike substance with no active ingredient) directly into the extraction site and a capsule that also may contain flurbiprofen or placebo. One in seven patients will receive only placebo. All patients will fill out pain questionnaires and stay in the clinic for up to 6 hours for observation of bleeding and medication side effects. Patients who do not have satisfactory pain relief from the test medicine after surgery may request a standard pain reliever. A small blood sample will be collected during surgery and at 15 minutes, one-half hour and 1, 2, 3, 4, 5, 6, 24 and 48 hours after surgery to measure flurbiprofen blood levels. A total of 33 ml (about 2 tablespoons) of blood will be drawn for these tests. Samples collected on the day of surgery will be drawn from the catheter used to administer the sedative; the 24- and 48-hour samples will be taken by needle from an arm or hand vein. Urine samples will also be collected between 4 and 6 hours after surgery and again at 24 and 48 hours after surgery.
NCT00001784 ↗ Mexiletine for the Treatment of Focal Dystonia Completed National Institute of Neurological Disorders and Stroke (NINDS) Phase 2 1998-07-01 Dystonia refers to a condition characterized by involuntary muscle contractions that may cause pain, abnormal posture, or abnormal movements. The cause of dystonia is unknown, but some researchers believe it is a result of overactivity in the areas of the brain responsible for movement (basal ganglia). Lidocaine is a drug used for the treatment of irregular heartbeats. It is given by injection. Recent studies have shown that lidocaine is also effective for the treatment dystonia. Mexiletine is a drug similar to lidocaine used for irregular heartbeats that can be taken by mouth. Researchers would like to test the effectiveness of Mexiletine for the treatment of dystonia. Patients participating in the study will be divided into two groups; Group 1 will take Mexiletine for six weeks then stop. They will remain drug free for one week then begin taking a placebo "inactive sugar pill" for an additional six weeks. Group 2 will take a placebo "inactive sugar pill" for six weeks then stop. They will remain drug free for one week then begin taking a Mexiletine for an additional six weeks. Throughout the study researchers will test the effectiveness of the treatment by evaluating patients using clinical rating scales and neurophysiological studies. In addition, researchers will test patient's reflexes in an attempt to find out where mexiletine works in the nervous system.
NCT00002901 ↗ Docetaxel in Treating Patients With Solid Tumors and Abnormal Liver Function Completed National Cancer Institute (NCI) Phase 1 1996-12-01 RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase I trial to study the effectiveness of docetaxel in treating patients with advanced solid tumors that have not responded to standard therapy or for which there is no effective therapy.
