Drug Facts
| Class | Purine analog antimetabolite (adenosine analog) |
|---|---|
| Mechanism | Fluorinated purine nucleoside analog of adenosine. Phosphorylated intracellularly to active triphosphate (F-ara-ATP); incorporated into DNA + RNA, inhibits ribonucleotide reductase + DNA primase + DNA polymerase α → S-phase arrest + apoptosis. Profoundly immunosuppressive (T-cell depletion → ideal for CAR-T lymphodepletion). Historically used in CLL (FCR), salvage lymphoma regimens, alloHCT conditioning. |
| Typical dosing | CAR-T lymphodepletion: 30 mg/m² IV daily × 3-4 days. CLL FCR: 25 mg/m² IV days 1-3 every 28 days × 6 cycles. Salvage lymphoma (FluMel conditioning): 30 mg/m² IV days 1-5. Renal dose adjust: CrCl 30-70 mL/min reduce 25%; CrCl <30 mL/min consider avoiding or reduce 50%. |

Warnings
- Severe + prolonged myelosuppression
- Severe immunosuppression (CD4 lymphopenia + opportunistic infection — PJP, CMV, HSV reactivation)
- Transfusion-associated GVHD — irradiate ALL blood products lifelong post-fludarabine
- Autoimmune hemolytic anemia (in CLL particularly)
- Neurotoxicity at high doses (encephalopathy, cortical blindness)
Notes
Backbone of CAR-T lymphodepleting conditioning (Flu/Cy). Also historic CLL backbone (FCR), now largely supplanted by BTKi / BCL2i. CRITICAL: irradiate ALL blood products LIFELONG after fludarabine exposure to prevent transfusion-associated GVHD. PJP + viral prophylaxis mandatory during + ≥6 months after treatment. Renal dose adjustment essential. Ukraine: registered + НСЗУ-reimbursed.
