4 Clinical Trials for Various Conditions
Verapamil has been found in some but not all studies to have antimanic activity. Therefore, we investigated the use of verapamil, alone or as an adjunctive treatment, in manic patients who did not respond to an initial adequate trial of lithium. Each study phase lasted three weeks. Subjects were treated openly with lithium in Phase 1 (n=45). Those who failed to respond were randomly assigned to double-blind treatment in Phase 2 with either verapamil (n=10) or continued lithium (n=8). Phase 2 responders were continued on the same medication in Phase 3. Phase 2 nonresponders (n=10) were assigned to combined verapamil/lithium in Phase 3.
The purpose of this study is to evaluate the safety and effectiveness of clozapine as a treatment for the manic phase of bipolar disorder. A significant proportion of manic patients either do not respond adequately to conventional treatment or cannot tolerate the adverse effects associated with therapeutic doses of these agents. Clozapine may be a safe and effective treatment for mania. However, the efficacy of clozapine as an alternative therapy in treatment-resistant bipolar disorder mania has not been extensively researched. The study will be conducted in three phases. Phase 1 is a screening phase that will take place for 2 to 7 days. Participants will undergo a baseline positron emission tomography (PET) scan of the brain at the end of this period. In Phase 2, participants will be randomly assigned to receive either clozapine or placebo (an inactive pill) for 3 weeks. They may also receive lorazepam for the first 10 days of Phase 2. After 3 weeks, patients treated with clozapine will undergo a second PET scan. During Phase 3, participants who received placebo and did not improve will be offered clozapine for 3 weeks. Those who received clozapine and did not improve will receive other treatment for 3 weeks. At the end of Phase 3, participants who were treated with clozapine will have another PET scan.
The purpose of this study is to investigate the efficacy of allopurinol as an augmentation agent for treatment resistant mania and mixed mania.
The overall objective of the investigators is to assess the therapeutic efficacy and tolerability of Allogeneic Bone Marrow Derived Multipotent Mesenchymal Stromal Cells (MSCs) isolated from hematogenous bone marrow for treatment of treatment-resistant bipolar depression patient (TRBD).
