To support its first in-patient trial, a sensitive and rapid method was developed and validated using ultra-performance LC–MS/MS. Materials & methods: JRF103 was extracted from plasma using protein precipitation. Extracts were subjected to ultra-performance LC–MS/MS with electrospray ionization. Results: Separation of analyte was achieved using a 1.7-μm C18 column (2.1 × 50-mm internal diameter) with a gradient...
