title: Outcomes assessment of drug treatment in multiple sclerosis clinical trials.
abstract: The purpose of this review is to evaluate the clinical outcomes of drug therapy in the treatment of multiple sclerosis (MS) in those studies which purported to include an assessment of quality of life. Pharmacological management of MS is primarily directed towards control of symptoms and prevention of disease progression or relapse. Although there are many drug and nondrug approaches used in the treatment of MS, this review focuses largely on approaches that incorporate some method of clinical outcome assessment. To aid in the interpretation of the data presented, a short descriptive summary of these assessment methods has been included. Although most studies incorporate at least one clinical outcome measure into the evaluation of efficacy, only one study has examined the economic impact of intervention in MS. The authors of that study demonstrated good correlation between the level of disability assessed using conventional quality-of-life measures and associated healthcare costs. Surprisingly, although many treatment approaches used in MS have significant associated toxicity and only modest benefits in terms of disease control, there is a remarkable paucity of data on the impact of these treatments on patients' quality of life. Studies that incorporate pharmacoeconomic and health-related quality-of-life consequences related to the treatment of MS are required.
