In combination with Rituximab this regimen is called R-FCM or R-FMC, or FCM-R, FMC-R.
The [R]-FCM regimen contains
- (R)ituximab - anti-CD20 monoclonal antibody that can kill both normal and malignant CD20-bearing B cells;
- (F)ludarabine - an antimetabolite;
- (C)yclophosphamide - an alkylating antineoplastic agent from the oxazafosforine group;
- (M)itoxantrone - a synthetic antracycline analogue (antraquinone) that can intercalate DNA, thereby preventing cell division.
The FCM or R-FCM regimen is also sometimes used in some autoimmune diseases that are inherently sensitive to the use of rituximab, fludarabine, mitoxantrone, and cyclophosphamide alone in monotherapies (e.g., in severe multiple sclerosis flares).
