    Abstract: Systems and methods for an analysis of clinical trial data using randomization tests that honors the randomized design of the clinical trial are provided herein. In particular, a non-parametric analyzer implementing randomization tests and associated methods for analyzing clinical data is provided. The non-parametric analyzer receives clinical trial data comprising a data structure containing data corresponding to subjects in the clinical trial, where the subjects have been organized into treatment groups, including at least one control group. The non-parametric analyzer generates multiple treatment allocations of the data structure by reorganizing, at random, the subjects along with corresponding data to generate further groups. In some embodiments, the non-parametric analyzer determines the statistical significance based on an overall probability and the multiple allocations of the data structure. The overall probability may be generated via a combination analysis for comparing test statistics between groups of the data structure and the multiple allocations.

    Abstract: The invention relates to a purified Isometheptene compound comprising the structure according to Formula (I), or a hydrochloride, or a pharmaceutically acceptable addition salt thereof. In particular, the disclosure relates to the synthesis, purification and characterization of an Isometheptene isomer mucate crystal 2, wherein the Isometheptene isomer 2 is stereochemically characterized as (R)-enantiomer, respectively. The Isometheptene (R)-enantiomer activity indicates a selective centrally acting selective ligand for Imidazoline subtype 1 (I1) receptor sites; and more specifically, the disclosure provides an antihypertensive composition for treatment of migraine and other neurovascular or neurogenic pain from abdominal distress. (R)-Isometheptene enantiomer or isomer 2 may be an anti-hypertensive agent with lower side effects than the racemate form. Therefore (R)-Isometheptene is believed to be effective against episodic tension-type headaches (ETTH). The (R)-Isometheptene enantiomer or isomer 2 is believed to effectively lower blood pressure, used alone or together with other headache ameliorating drugs. Methods of synthesis and treatment are described. Regarding (R)-Isometheptene crystals data of X-ray crystallography are presented.
