Frontage Laboratories Bioanalytical Group Publishes 3 Novel Methods
Published: Mar 07, 2012
The first of the three new methods resulted from a Frontage partnership with Sunovion Pharmaceuticals, Inc. Highly sensitive and specific, the 2-in-1 LC-MS/MS method measures human serum levels of ciclesonide, a once-daily inhaled corticosteroid, and its active metabolite at a lower limit of quantitation of one picogram per milliliter. This concentration is lower than any level found with previously published methods.
The second new Frontage method is the first one available that enables simultaneous quantitation of ethinyl estradiol and norgestimate, which is a combination oral contraceptive, as well as a metabolite of norgestimate. The Bioanaltyical group overcame the challenging sensitivities, interferences and instability issues that had prevented previous analytical methods from simultaneously quantifying all three analytes.
Finally, Frontage developed a novel and ultrasensitive method for determining human plasma levels of fluticasone furoate, an enhanced-affinity glucocorticoid used to treat allergy symptoms. This technique employs liquid chromatography tandem mass spectrometry using atmospheric pressure photoionization with a novel mobile phase incorporated dopant to increase sensitivity and specificity. With a lower limit of quantitation of 0.2 picograms per milliliter, the ultrasensitive method fulfills a need specified by clinical bioequivalence trials.
