A rapid and highly sensitive HILIC-HPLC based analytical assay method for quantification of azacitidine and venetoclax in a single run

Abstract

Venetoclax and Azacitidine combination has recently been approved by the USFDA to treat old people with acute myeloid leukemia. Pharmaceutical formulations of the combination of these two drugs are expected to be launched soon. Till date, an analytical method of any type has not been reported in literature for quantification of Venetoclax and Azacitidine in a single run. The current work set out to establish an HILIC-HPLC based analytical assay method for simultaneous quantification of Azacitidine and Venetoclax from the mixed sample. The method has been developed employing Poroshell HILIC column. Ammonium formate (10 mM, pH 5.0) and acetonitrile were used as a mobile phase in gradient programme. A variety of parameters, including linearity, accuracy, precision, specificity, robustness, and ruggedness were evaluated to validate the method. Azacitidine and Venetoclax were eluted at 8.8 min and 4.0 min, respectively. Method was linear over the range of 1-100 µg/mL. Recovery was found to be 98.29-99.28% and 101.84-101.95% for Azacitidine and Venetoclax, respectively. The method was reproducible with a relative standard deviation of less than two in precision studies. The developed method can suitably be employed for quantifying Venetoclax and Azacitidine in a single run from their mixed samples.
