The 13th annual WRIB (Workshop on Recent Issues of Bioanalysis) was held in New Orleans, LA this week and is wrapping up today. The workshop was well represented by regulators and industry (both from Pharma and CROs), with numerous discussions and topics for the bioanalysis of small and large molecules. Presentations covered the full spectrum […]
Today, the FDA issued twenty-two new bioequivalence recommendations, some of which were for some fairly old products, including a couple of DESI drugs. There were no surprises in the newly issued listings; however, as we have gone on about previously, the FDA has also issued fifty-two – yes, fifty-two – revisions to previously issued guidances. […]
Linaclotide capsules are “minimally absorbed with negligible systemic availability following oral administration. Concentrations of linaclotide and its active metabolite in plasma are below the limit of quantitation after oral doses of 145 mcg or 290 mcg were administered. Therefore, standard pharmacokinetic parameters such as area under the curve (AUC), maximum concentration (Cmax), and half-life (t½) […]

While we are thankful for the FDA’s work on issuing bioequivalence guidance documents, we worry about the impact of the constant and sometimes significant revisions to previously issued draft or final bioequivalence guidance recommendations on the review and approval process. It seems that we are not alone! In remarks made at the November 27th FDA […]
While the FDA does appear to listen rather intently to comments on its bioequivalence (BE) draft guidances, and will occasionally reopen comment periods, it is still the exception rather than the rule. Today a Federal Register (FR) notice (here) announced another sixty-day comment period during which such comments will be entertained. The FR notice explains […]
