Never Exposed to Cladribine
All participants who received placebo matched to cladribine in previously conducted clinical trials (NCT Number: NCT00213135, NCT00436826 , NCT00641537, NCT00938366 and NCT00725985).

Exposed to Cladribine
All participants who received cladribine in previously conducted clinical trials (NCT Number: NCT00213135, NCT00436826, NCT00641537, NCT00938366 and NCT00725985).

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Participants With Serious Adverse Drug Reactions (SADRs)
Time Frame: up to 3251 days
|
SADR is an adverse drug reaction that fulfils at least one of the seriousness criterion; results in death, is life-threatening, requires in-patient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, is otherwise considered as medically important.
An adverse drug reaction (ADR) is a response to a medicinal product which is noxious and unintended, and which occurs at doses normally used in man for prophylaxis, diagnosis, or therapy of disease or for the restoration, correction, or modification or physiological functions.
Number of participants with SADRs were reported.

up to 3251 days

Time to Resolution of Lymphopenia, Among Registry Participants With Persistent Lymphopenia
Time Frame: up to 3251 days
|
Persistent lymphopenia was defined as Grade 3 (less than [<] 500-200 per millimeter [mm] ^3 or < 0.5-0.2
multiply [*]10^9 per Liter) or Grade 4 (< 200/mm^3 or < 0.2*10^9 per Liter) lymphopenia as defined by the Common Terminology Criteria for Adverse Events (CTCAE) version 3.0.
The resolution is the achievement of a CTCAE Grade 1 (< lower limit of normal [LLN] to 800 per mm^3 or < LLN to 0.8*10^9 per Liter) or Grade 0 (< 910 per mm^3 ) lymphocyte count.
Persistent Lymphopenia was reported only in Cladribine group, hence results are reported only for "Exposed to Cladribine" arm.
Time to resolution is reported.
|
up to 3251 days
|
Number of Participants With Adverse Events (AEs) in the "Blood and Lymphatic System Disorders" System Organ Class (SOC) and in the "Neoplasms Benign, Malignant, and Unspecified" SOC
Time Frame: up to 3251 days
|
An Adverse event (AE) was defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of study drug, whether or not considered related to the study drug or worsening of pre-existing medical condition, whether or not related to study drug.
|
up to 3251 days

Measure Description |
Time Frame |
---|---|---|
Number of Participants With Pregnancy Outcomes
Time Frame: up to 3251 days
|
Pregnancies occurred among female participants exposed to cladribine were identified by a participant-reported positive pregnancy test and at least a 2-week delay in menses, or a participant-reported pregnancy diagnosed by a physician.
Pregnancy outcomes were Live birth, Induced abortion (Termination), Spontaneous loss (Miscarriage) (< 22 weeks), Foetal death (stillbirth) (>=22 weeks), Ectopic pregnancy, Congenital malformations and others (unknown).
Number of participants as per pregnancy outcome category were reported.
