The present application relates to a compound which may be useful for mediating NO production and improving L-arginine bioavailability in a subject. Pharmaceutical compositions comprising the compound and methods of using the compound are also provided.

Compound for improving L-arginine bioavailability

Disclosed herein are novel assays, systems and kits for selecting a treatment regimen for a subject with depression by identifying at least one nucleic acid polymorphism, e.g., but not limited to, at the MTHFR, MTR, or MTRR locus, and/or determining expression levels of peripheral biomarkers (e.g., SAM, SAH, 4-HNE, and/or hsCRP) in a test sample from a human subject. These biomarkers can be used to determine the effectiveness of treating a depressed subject with a folate-containing compound (alone or as an adjunct to an antidepressant). Additionally, these biomarkers can be used to select an appropriate treatment regimen for subjects with treatment-resistant depression (e.g., resistant to at least one selective serotonin reuptake inhibitor). Methods and compositions for treating at least one symptom (e.g., at least one core symptom) of depression in a subject and/or determining or improving the effectiveness of an antidepressant drug taken by a subject are also provided herein.

A method and system for performing a clinical trial having a reduced placebo effect is disclosed. The method includes randomizing study participants into three or more treatment groups and performing a first phase of testing on the groups. In a typical embodiment, the first phase of testing includes administering an active treatment to a first group, and administering a placebo to a second group and to a third group. Responders and non-responders are determined for each group. A second phase of testing is then performed. The second phase of testing includes administering the placebo to non-responders in the first group, administering the active treatment to non-responders in the second group, and administering the placebo to non-responders in the third group. The data from the first phase of testing and from the second phase of testing is pooled and analyzed to determine response rates to active treatment and placebo.
