Overview
Brief Summary
This is a retrospective, observational, multicenter study to collect Real-World Evidence (RWE) data on systemic AL-AMY patients in Europe. Data from paper/electronic medical records and/or electronic databases from key reference centers in Europe will be used. Data will either be entered by the site staff in the electronic Case Report Form (eCRF) or, where feasible, transferred directly, always in accordance to local regulations.
Detailed Description
The lack of regulatory approved treatment options for AL amyloidosis (AL-AMY) justifies the need to understand the current treatment practice and outcomes of this disease. There is a need for objective Real-World Evidence (RWE) that reflects how treatments are initiated, combined and sequenced, and how their relative effectiveness and safety profiles emerge outside a clinical trial setting. Therefore, the aim is to generate RWE on systemic AL-AMY patients in Europe, including patient characteristics, resource use, treatments and associated patient outcomes.

Eligibility Criteria
Inclusion Criteria
- •Age\>18 years
- •Confirmed diagnosis of AL-AMY and symptomatic organ involvement.
- •Initiated first line treatment for AL-AMY in the period 2004-
- •Patients who have signed a participation agreement/ICF allowing data collection and source data verification in accordance with local requirements.
- •The inclusion of deceased subjects in the study is permitted under the condition that consent waiver has been granted by the Scientific Committee and/or Administrative Board of the participating sites and/or any applicable regulatory body, as per local regulations, to either implement a hospital informed consent form (ICF) already in place or provide written approval of this study-specific waiver. In the occasion that waiver of consent is not granted deceased subjects will not be enrolled in the study.
Exclusion Criteria
- •Patients under the age of 18 will not be considered eligible for this study
Outcomes
Primary Outcomes
Patient and disease characteristics
Time Frame: 2004-2018
To describe the proportion of patients belonging to different age groups, and the proportion of patients per gender, stage, organ involvement, performance status, and hematologic biomarkers at screening or at baseline; by first-line treatment initiation period (pre-2010 or post-2010) and overall.
Treatment patterns
Time Frame: 2004-2018
To describe the proportion of patients who had an autologous stem cell transplantation by first-line initiation period (pre-2010 or post-2010) and overall; the proportion of regimen combinations used by line of treatment, and by first-line initiation period; the proportion of patients receiving specific regimen combinations following different first-line regimens, by first-line initiation period and overall.
Response evaluation and efficacy outcomes
Time Frame: 2004-2018
To describe the treatment effectiveness in terms of hematologic response rates at 3, 6, 12, and 24 months after first-line initiation, by regimen and first-line initiation period (pre-2010 or post-2010); overall survival, progression-free survival, and time on treatment, overall, by first-line treatment and by first-line initiation period.
