Toxicity
Azacitidine causes anemia (low red blood cell counts), neutropenia (low white blood cell counts), and thrombocytopenia (low platelet counts), and patients should have frequent monitoring of their complete blood counts, at least prior to each dosing cycle. The dose may have to be adjusted based on nadir counts and hematologic response.It can also be hepatotoxic in patients with severe liver impairment, and patients with extensive liver tumors due to metastatic disease have developed progressive hepatic coma and death during azacitidine treatment, especially when their albumin levels are less than 30 g/L. It is contraindicated in patients with advanced malignant hepatic tumors.Kidney toxicity, ranging from elevated serum creatinine to kidney failure and death, have been reported in patients treated with intravenous azacitidine in combination with other chemotherapeutic agents for conditions other than myelodysplastic syndrome. Renal tubular acidosis developed in five patients with chronic myelogenous leukemia (an unapproved use) treated with azacitidine and etoposide, and patients with renal impairment may be at increased risk for renal toxicity. Azacitidine and its metabolites are primarily excreted by the kidneys, so patients with chronic kidney disease should be closely monitored for other side effects, since their levels of azacitidine may progressively increase.Based on animal studies and its mechanism of action, azacitidine can cause severe fetal damage.
