| OTC | NCT00405912 ↗ | St. John's Wort for Tobacco Cessation | Completed | National Cancer Institute (NCI) | Phase 2 | 2005-09-01 | After a steady decline for the last 50 years, the prevalence of tobacco use in the United States has reached a plateau of approximately 23%. Currently available treatments among adults are expensive and not efficacious for all tobacco users. New pharmacologic agents need to be developed and tested to achieve the Healthy People 2010 goal of less than a 12% adult tobacco use prevalence. Bupropion, an FDA approved agent for tobacco cessation, acts by inhibiting central synaptosomal reuptake of dopamine and norepinephrine. A widely used herbal antidepressant, St. John's Wort (SJW), shares a similar mechanism of action and is effective for treating mild to moderate depression. SJW is well tolerated, available over the counter, and is significantly less expensive than the established treatments for tobacco dependence. To date, no prospective clinical trial evaluating the efficacy of SJW for the treatment of tobacco use has been published. We propose to evaluate the efficacy of SJW for increasing tobacco abstinence and decreasing nicotine withdrawal symptoms in a randomized, double-blind, placebo-controlled, three-arm, parallel group, dose-ranging clinical trial. Participants (N=120) will be randomly assigned to one of the three groups and will receive a twelve-week course of SJW 900 mg per day, 1800 mg per day, or a matching placebo. This study is anticipated to provide the data needed to develop a larger randomized controlled clinical trial submitted through the R01 funding mechanism. |

| New Formulation | NCT00640159 ↗ | Tolerability and Efficacy of Switch From Oral Selegiline to Orally Disintegrating Selegiline (Zelapar) in Patients With Parkinson's Disease | Completed | Baylor College of Medicine | Phase 4 | 2007-01-01 | Parkinson's disease (PD) is a progressive neurodegenerative disease. Symptomatic therapy is primarily aimed at restoring dopamine function in the brain. Oral selegiline in conjunction with L-dopa has been a mainstay of therapy for PD patients experiencing motor fluctuations for many years. The mechanisms accounting for selegiline's beneficial adjunctive action in the treatment of PD are not fully understood. Inhibition of monoamine oxidase (MAO) type B (MAO-B) activity is generally considered to be of primary importance. Oral selegiline has low bio-availability and is typically dosed BID, for a total of 5-10 mg daily. Recently, the FDA approved a new orally disintegration tablet (ODT) formulation of selegiline, called ZelaparTM. This new formulation utilizes Zydis technology to dissolve in the mouth, with absorption through the oral mucosa, thereby largely bypassing the gut and avoiding first pass hepatic metabolism. This allows more active drug to be delivered at a lower dose. Consequently, Zelapar is dosed once-daily, up to 2.5 mg per day. There are no empirical data indicating whether the use of the new approved formulation of selegiline ODT (Zelapar) is superior or preferred by patients compared to traditional oral selegiline. It is believed that clinical efficacy will be preserved or enhanced, by delivering more active drug, with improved patient preference for the ODT formulation due to the once-daily dosing . The effectiveness of orally disintegrating selegiline as an adjunct to carbidopa/levodopa in the treatment of PD was established in a multicenter randomized placebo-controlled trial (n=140; 94 received orally disintegrating selegiline, 46 received placebo) of three months' duration. Patients randomized to orally disintegrating selegiline received a daily dose of 1.25 mg for the first 6 weeks and a daily dose of 2.5 mg for the last 6 weeks. Patients were all treated with levodopa and could additionally have been on dopamine agonists, anticholinergics, amantadine, or any combination of these during the trial. At 12 weeks, orally disintegrating selegiline-treated patients had an average of 2.2 hours per day less "OFF" time compared to baseline. Placebo treated patients had 0.6 hours per day less "OFF" time compared to baseline. These differences were significant (p < 0.001). Adverse events were very similar between drug and placebo. |
| OTC | NCT00722124 ↗ | S-Adenosyl-L-Methionine (SAMe) for Smoking Abstinence | Completed | Pharmavite | Phase 2/Phase 3 | 2008-09-01 | Cigarette smoking is of great public health importance and is the single most important preventable cause of morbidity, mortality and excess health care costs in the United States. After a steady decline for the last 50 years, the prevalence of tobacco use in the United States has reached a plateau of approximately 21%. Currently available treatments among adults are not efficacious for all tobacco users. New pharmacologic agents thus need to be continually developed and tested. The release of dopamine in the nucleus accumbens is one of the key components of the pleasurable and rewarding effects of nicotine. Drugs that increase monoamine neurotransmitter availability (particularly dopamine and norepinephrine) are likely to increase the reward function and thus ameliorate withdrawal symptoms. S-Adenosyl-L-Methionine (SAMe), the primary methyl donor for the central nervous system (CNS), donates methyl groups towards presynaptic synthesis of CNS monoamine neurotransmitters. By facilitating the synthesis of dopamine and norepinephrine in the brain, SAMe is likely to ameliorate the symptoms of nicotine withdrawal, thus improving tobacco abstinence rates in smokers who are trying to stop smoking. SAMe is well tolerated and is available over-the-counter. To date, no prospective clinical trial evaluating the efficacy of SAMe for the treatment of tobacco dependence has been published. We propose to evaluate the efficacy of SAMe for increasing smoking abstinence and decreasing nicotine withdrawal symptoms in a randomized, blinded, placebo-controlled, three-arm, parallel-group, dose-ranging phase II clinical trial. Participants (N=120) will be randomly assigned to one of the three groups, and will receive an 8-week course of SAMe 800-mg per day, 1600-mg per day, or a matching placebo. This study is anticipated to provide the data needed to develop a larger randomized controlled clinical trial submitted through the R01 funding mechanism, if the results appear promising. |
