WOE of Anti-CD20 Therapies

The nature, intensity, and prevalence of this wearing-off effect remain poorly understood. To our knowledge, there is no consensus in the literature on what symptoms constitute a wearing-off effect, nor is there a single validated scale that measures wearing-off effect. The current study will explore the wearing-off effect associated with OCR and OMB, using a variety of validated scales assessing MS symptoms (i.e., fatigue, mobility, pain, depression, cognition), as well as some global questions on wearing-off. In addition, impact of worsening of MS symptoms on patients' health-related quality of life (HRQoL) and their work productivity will be assessed using relevant MS-specific validated scales

Physical and psychological scale scores are generated by summing individual items and then transformed to a 0 (best) -100 (worst) scale. The MCID for the physical impact score (6.8) and psychological impact score (7.4) are based on the work from (Greene, et al., 2023).

  3. Mean score change for each of the 4 domains of the Work Productivity and Activity Impairment Questionnaire for MS (WPAI:MS)

    Time frame: Up to 10 days before index dose (first dose) post enrollment, from 5 to 14 days after index dose, up to 10 days before second dose post enrollment, from 5 to 14 days after second dose.

    The Work Productivity and Activity Impairment: MS (WPAI:MS) questionnaire is a well validated instrument measuring the effect of MS on work productivity and regular activities during the past seven days. The questions are computed according to specific calculation rules and have four scores: (1) percentage work time missed due to health (absenteeism); (2) percentage impairment at work due to health (presenteeism); (3) percentage overall work productivity loss due to MS; and (4) percentage daily activity impairment outside of work due to MS. Scale for each of the 4 domains is 0% (best) - 100% (worst).
