Abstract
Background: A LC-MS/MS method was validated for the quantification of SUVN-G3031, a novel H3 receptor inverse agonist in clinical development for the treatment of patients with narcolepsy, with and without cataplexy. Methodology: SUVN-G3031 was extracted from plasma following acetonitrile protein precipitation, separated by Ultra HPLC and quantified using positive ESI-MS/MS. Results: The method was linear across the range of 0.1-100 ng ml-1 in plasma. Results for intra and inter-day accuracy were from 99.8 to 104% and precision (%CV) was ≤10.6%. Conclusion: The method was applied to a first-in-human study in healthy volunteers. The method is precise, accurate and highly selective for the quantification of SUVN-G3031 in human plasma.
