that the mean maximal QT prolongation occurred within 1 min of drug administration, at the same time as a significant increase in HR.
The maximal QTc prolongation occurred during or within 15 min of completion of the drug infusion with a return to baseline generally over 4 6 h.
In addition, after reaching the maximal yields, further prolongation of reaction time would result in the decreased product yields in all cases, which may be attributed to the occurrence of the side reaction enzymatic hydrolysis of the desirable product N-bromoacetyl-7-ACA.
Based on these, the mean maximal relative PT prolongation in the present study was expected to be 1.62, with a CV of 30%, and the aim was to achieve a maximal relative PT prolongation of ≤2-fold of the baseline value.
Study sensitivity was confirmed with moxifloxacin demonstrating a significant maximal time-matched QTcF prolongation of 13.90 10.588, 17.22) ms compared to placebo.
The kinetic characteristics [including AUC from time 0 to the last data point (AUC(0– tn )) and maximal effect (Emax)] of PT prolongation were analysed in an explorative manner.
Using CsA as a positive control, we observed a prolongation in time to 50% of maximal response, representing protection from mPTP opening.
In all three murine obesity models used in our study, both aging and obesity independently triggered an elongation in resting cell length, depression in peak shortening (PS) amplitude and maximal velocity of shortening/relengthening amplitude (± dL/dt), as well as prolongation in relengthening duration (TR90) but not duration of shortening (TPS).
The clotting time prolongation closely followed the apixaban concentration time profile, such that the maximal clotting time occurred near the apixaban tmax, and returned to baseline coincident with the apixaban elimination phase.
According to a strict QT/QTc evaluation study and clinical studies for type 2 diabetes conducted in Japan and other countries, no AEs related to QT prolongation were detected with 40 mg/day of teneligliptin, which is the maximal dosage used in clinical practice.
