| NCT01553318 ↗ | Novel Use of (Oral) Ketotifen for the Treatment of Fibromyalgia: A Pilot Study | Completed | Indiana University | Phase 3 | 2012-03-01 | The purpose of this 10-week study is to determine the effects of a medication called Ketotifen on pain sensitivity; and fibromyalgia-related pain. Ketotifen works by inhibiting (to prevent or slow down) certain substances in the body that are known to cause inflammation. It is an antihistamine that reduces the harmful effects of histamine. The ophthalmic (eye drops) formulation of ketotifen has been approved by the Food and Drug Administration (FDA) and has been available in the United States for more than a decade. Oral (taken by mouth) ketotifen has been in available in other countries for several decades. Commonly prescribed for the maintenance treatment of asthma and allergic rhinitis, ketotifen has long track record of safety. To date, the oral form of ketotifen has not been approved by the FDA, therefore this study is referred to as an "investigational drug study." Prior to opening recruitment an "investigational new drug" (IND) application which included scientific data and information regarding human safety plans was submitted to and approved by the FDA. |
| NCT02673840 ↗ | Ketotifen as a Treatment for Vascular Leakage During Dengue Fever | Unknown status | Duke-NUS Graduate Medical School | Phase 4 | 2015-03-01 | Rationale and Aims: Infection by dengue virus (DENV) causes major morbidity and mortality throughout the world. In 2012, an estimated 3.6 billion people live in areas at risk for DENV infection, including Singapore. The key pathology of DENV infection is vascular leakage, which can occur in mild cases and can become life-threatening in severe cases when patients may develop dengue hemorrhagic fever (DHF) or dengue shock syndrome (DSS). Mast cells (MCs) are strongly activated by DENV with preliminary studies showing that activation levels are correlated to disease severity in human patients. Thus, the investigators propose to use the MC stabilizing drug, ketotifen, to limit the immune pathology that is characteristic of dengue infection and treat dengue-induced vascular leakage. Methods: The ability of Ketotifen to reduce vascular leakage in DENV patients will be determined by assessing the pooling of fluid in the pleural cavity (measured by MRI and CXR) after 5 days of drug administration, evaluated as a percent change compared to baseline fluid levels. Additional measures of vascular leakage and immune pathology will be compared as secondary objectives. The trial will be conducted as a randomized, double-blind study comparing the responses of dengue patients given either ketotifen or placebo (n=55 per arm). Importance of proposed research: Currently, no targeted treatments exist to limit vascular leakage during DENV infection. If Ketotifen is identified as effective for preventing pleural effusion and/or plasma leakage in DENV patients, this would constitute an advance for the clinical management of DENV fever. This finding would also support a large-scale trial to determine whether Ketotifen can be used to prevent severe vascular leakage as occurs during DHF/DSS. Benefits/Risks: Ketotifen has a record of safety and tolerability in humans, regulatory approval, and widespread use. Side effects are generally mild. The potential exists that, if effective, many of the painful and life-threatening symptoms of DENV infection that result from plasma leakage would be improved. |
