    摘要： The invention provides methods and systems for assessing the efficacy of a pharmaceutical which is putatively disease modifying of a cognitive disorder, for use in the treatment or prophylaxis of that cognitive disorder, the method comprising the steps of: (1) stratifying a subject group into at least 2 sub-groups according to a baseline indicator of likely disease progression, (2) treating members of each subject group with the pharmaceutical for a treatment time frame, (3) deriving psychometric and optionally physiological outcome measures for each treated patient group, (4) comparing the outcomes at (3) with a comparator arm of said sub-groups which is optionally a placebo or minimal efficacy comparator arm, (5) using the comparison in (4) to derive an efficacy measure for the pharmaceutical. The methods and systems of the invention address problems such as low rate of decline over the treatment time-frame of patients who have mild-disease severity at baseline and biased withdrawal, particularly in the placebo/comparator treatment arm.

    摘要： This invention pertains generally to the field of chemical synthesis and purification, and more specifically to methods of synthesizing and purifying certain 3,7-diaminophenothiazin-5-ium compounds (referred to herein as “diaminophenothiazinium compounds”) including Methythioninium Chloride (MTC) (also known as Methylene Blue). In one embodiment, the method comprises the steps of, in order: nitrosylation (NOS); nitrosyl reduction (NR); thiosulfonic acid formation (TSAF); oxidative coupling (OC); Cr(VI) reduction (CR); isolation and purification of zwitterionic intermediate (IAPOZI); ring closure (RC); chloride salt formation (CSF); one of: sulphide treatment (ST); dimethyldithiocarbamate treatment (DT); carbonate treatment (CT); ethylenediaminetetraacetic acid treatment (EDTAT); organic extraction (OE); and recrystallisation (RX). The present invention also pertains to the resulting (high purity) compounds, compositions comprising them (e.g., tablets, capsules), and their use in methods of inactivating pathogens, and methods of medical treatment and diagnosis, etc., for example, for tauopathies, Alzheimer's disease (AD), skin cancer, melanoma, viral diseases, bacterial diseases, or protozoal diseases.
