Retrospective Viability Study of the PETHEMA-POMCIDEX Clinical Practice Guidelines for the Treatment of Patients With Relapsed and Refractory Multiple Myeloma (RRMM)

This is a national, multicentre, observational, retrospective, open-label, non-randomized, non-interventional study to evaluate the degree of compliance at PETHEMA centres in Spain with the clinical practice guidelines proposed by the Spanish Myeloma Group for the treatment of relapsed and refractory MM with POMCIDEX. In this study, all patients will be included retrospectively who met the inclusion criteria for the GEM clinical practice guidelines and who were treated with POMCIDEX. The period of retrospective data collection will be from 01/01/2015 to 01/04/2018. The period of data collection for the study includes a maximum period of three months to allow each centre to collect the necessary clinical and demographic data for each patient in order to fulfill the different study objectives. Patient data will be anonymized and recorded in the electronic Case Report Form (eCRF) using the RedCap platform. Afterward, data cleansing and verification will be carried out on all data recorded by the study investigators. This procedure will be carried out in the six months after database lock. Once the process of recording and verification of patient data is complete, extraction and statistical analysis of the data will be carried out.
