• Drug Exposure— Documented use of the implicated medication (e.g., lenalidomide, pomalidomide, carfilzomib, daratumumab) for a minimum duration (commonly 6 months+).
• Injury Link— Alleged damage that falls within the claimed danger category (e.g., 2nd main malignancy, major cardiovascular event, extreme infection, liver disease B reactivation).
• Geographical Jurisdiction— Residency or treatment area within the jurisdiction where the class is licensed (some classes are across the country; others are state‑specific).
• Exclusions— Individuals who have actually currently settled specific claims, pulled out of a prior class, or signed a release agreement with the accused might be barred.
