A Study of Suboptimally Controlled Participants Previously Taking Injectable DMDs for RMS (CLICK-MS)

Study Overview
=================
Brief Summary
-----------------
To evaluate the effectiveness, patient-reported outcomes (PROs) and safety of cladribine tablets in participants with relapsing forms of multiple sclerosis (RMS) including relapsing-remitting multiple sclerosis (RRMS) and active secondary progressive multiple sclerosis (aSPMS),who transition to cladribine tablets after suboptimal response to any injectable disease-modifying drugs (DMDs) approved in the United States (US) for RMS in a real-world setting.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Cladribine Tablets<br>No intervention will be administered as a part of this study. Participants who had decided prior to enrollment to transition from any injectable DMD to treatment with cladribine tablets under routine clinical care and who meet all eligibility criteria will receive an initial treatment course with cladribine tablets in Year 1 and are planned to receive a second course in Year 2, as per the approved United States Prescribing Information (USPI). Data sources for this study will include data extracts from participants' medical records performed by site personnel as well as questionnaires directly filled out by participants. | Drug: Cladribine Tablets<br>* No intervention will be administered as a part of this study. Participants will receive cladribine tablets as per investigator discretion and as per United States approved label: 3.5 milligram/kilogram (mg/kg) body weight over 2 years, administered as 1 treatment course of 1.75 mg/kg per year.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Annualized Relapse Rate (ARR) (Prospective Assessment) | For this study, a relapse will be defined as per routine clinical practice as determined by the investigator. As a guide, relapse may be defined as exacerbation of symptoms that occur over a minimum of 24 hours and separated from a previous attack by at least 30 days, in the absence of fever or infection. ARR up to 24 months of treatment with cladribine tablets, after baseline (prospectively collected data) will be reported. | Baseline (Month 0) up to 24 Months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change From Baseline in 14-Item Treatment Satisfaction Questionnaire for Medication (TSQM-14) Total Score at Month 6, 12 and 24 |  | Baseline (Month 0), Month 6, 12 and 24 | 
| Change From Baseline in 36-Item Short Form Health Survey (SF-36) Total Score at Month 6, 12 and 24 |  | Baseline (Month 0), Month 6, 12 and 24 | 
| Change From Baseline in Modified Fatigue Impact Scale - 5-item version (MFIS-5) Total Score at Month 6, 12 and 24 |  | Baseline (Month 0), Month 6, 12 and 24 | 
| Change From Baseline in 7-Item Beck-Depression Inventory-Fast Screen (BDI-FS) Total Score at Month 6, 12 and 24 |  | Baseline (Month 0), Month 6, 12 and 24 | 
| Change From Baseline in 6-Item Work Productivity Activity Impairment - Multiple Sclerosis (WPAI-MS) Total Score at Month 6, 12 and 24 |  | Baseline (Month 0), Month 6, 12 and 24 | 
| Change From Baseline in Patient Determined Disease Steps (PDDS) Scale Total Score at Month 6, 12 and 24 |  | Baseline (Month 0), Month 6, 12 and 24 |

| Percentage of Participants with Relapse (Prospective Assessment) | For this study, a relapse will be defined as per routine clinical practice as determined by the investigator. As a guide, relapse may be defined as exacerbation of symptoms that occur over a minimum of 24 hours and separated from a previous attack by at least 30 days, in the absence of fever or infection. Percentage of participants with relapse up to 24 months of treatment with cladribine tablets, after baseline (prospectively collected data) will be reported. | Month 12 and 24 |
