A simple, accurate, specific and rugged reverse phase liquid chromatographic method was developed for the simultaneous estimation of Nivolumab and Ipilimumab in bulk and tablet dosage form. A RP Inertsil ODS, having dimensions of 150 × 4.6 mm and particle size of 3.5 μ in isocratic mode, with mobile phase containing a mixture of 0.1% orthophosphoric acid and acetonitrile in the proportion (50:50 v/v). The mobile phase was pumped at a flow rate of 1.0 ml/min and the eluent were monitored at 225 nm.
