All subjects in the target population will be eligible for enrollment in the registry once their participation in the clinical trial has ended. The following inclusion criteria must be fulfilled:
• Prior enrollment into selected clinical trials, regardless of randomization to either IMP or placebo, once participation in the clinical trial or in the clinical trial extension has ended
• Written informed consent is given

Primary Outcome(s)

Timepoint(s) of evaluation of this end point: The cumulative incidence of SADRs and of AEs in the ‘Blood and Lymphatic System Disorders’ and ‘Neoplasms Benign, Malignant, and Unspecified’ SOCs will be summarized, and time to resolution of persistent lymphopenia will be estimated using the life table methodology.

Secondary Objective: To assess pregnancy outcomes, including congenital malformations or other important health conditions in the offspring born to women exposed to oral cladribine

Main Objective: • To quantify and characterize the risk (cumulative incidence) of serious adverse drug reactions, including malignancies and serious infections
• To assess time to resolution of lymphopenia among registry participants with persistent lymphopenia
• To quantify and characterize the risk (cumulative incidence) of adverse events in the ‘Blood and Lymphatic System Disorders’ and ‘Neoplasms Benign, Malignant, and Unspecified’ System Organ Classes

Primary end point(s): • Cumulative incidence of serious adverse drug reactions (SADRs), including malignancies and serious infections
• Time to resolution of lymphopenia, among registry participants with persistent lymphopenia
• Cumulative incidence of all adverse events (AEs) in the “Blood and Lymphatic System Disorders” System Organ Class (SOC) and in the “Neoplasms Benign, Malignant, and Unspecified” SOC

Secondary Outcome(s)

Secondary end point(s): Pregnancy outcomes, including congenital malformations, spontaneous abortion, elective abortion, stillbirth, ectopic pregnancy, molar pregnancy, and other important health conditions in the offspring

Timepoint(s) of evaluation of this end point: The proportion of women and the frequency of the pregnancy outcomes including congenital disorders and important health conditions in the offspring, will be descriptively summarized.
