Clinical Trial Summary

Multicentre, prospective, observational, open-label, single arm, post-marketing study intended to record Lenalidomide/Dexamethasone treatment data from patients with relapsed/refractory Multiple Myeloma (rrMM) treated under the settings defined by the standard clinical practice and approved Summary of Product Characteristics (SmPC).

Description:

This study aims to assess the real-life safety of Lenalidomide/Dexamethasone (Len/Dex) in patients with (Relapsed or Refractory Multiple Myeloma (rrMM), by evaluation of adverse events of special interest (infections, gastrointestinal events, thrombocytopenia, neutropenia, febrile neutropenia, and thromboembolism). In addition, due to the scarce information regarding the impact of frailty in Len/Dex treatment in rrMM, this study will prospectively assess Len/Dex safety and effectiveness by patient frailty groups.

The following study assessments will be performed:

• Recruitment: patients will be recruited within 15 days after the start of Len/Dex (from day 1 to day 15). In case patients are not recruited at the day of Len/Dex start (day 1), baseline information respective to this day will be collected retrospectively.

• Treatment period: during this period, the following assessments will be carried out:

• Every 30 days (± 5 days) for adverse events, changes in concomitant medication and change in Len/Dex dose.

• Every 90 days (± 15 days) for the remaining information to be collected in the treatment period

• Assessment at the end of Len/Dex treatment (until 5 days after end of treatment).

Follow-up assessment 90 days (± 15 days) after the end of Len/Dex treatment.

No visits were predefined for this study. Study data is planned to be collected when the patient goes to the study site for a clinical routine visit. No assessments will be imposed for the purposes of this study. If the patient goes to the clinical routine visit at a date out of the time intervals predicted above, no information will be collected. Information will be collected in the context of routine clinical practice.

The patient will be followed until the end of Len/Dex treatment, death or discontinuation for any reason for a maximum period of 36 months, Patients within treatment after this maximum period will stop being followed in the study.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Adverse events of special interest during Len/Dex therapy	Adverse event (AE): Any untoward medical occurrence in a patient administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment, i.e. any unfavourable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product whether or not considered related to the medicinal product. Progression of the underlying disease of multiple myeloma is not considered an AE and should not be reported as an AE	Up to approximately 72 months
Secondary	Incidence (number) of thromboembolism	Identification of the incidence of deep venous thrombosis and pulmonary embolism) during Lenalidomide and Dexamethasone study drug treatment.	Up to approximately 72 months
Secondary	Duration of Len/Dex treatment over the course of the study	Defined as the time between the start of Len/Dex treatment until discontinuation or death (whichever occurs first)	Up to approximately 72 months
Secondary	Number of patients with good and poor compliance to lenalidomide and dexamethasone	Compliance will be measured by the capsule/tablet count, after the end of study treatment	Up to approximately 72 months
Secondary	Type and frequency of prophylaxis treatment for prevention of thromboembolism	Type and frequency of prophylaxis treatment for prevention of thromboembolism during Lenalidomide/Dexamethasone study treatment.	Up to 36 months
