Multicomponent Pharmacokinetic Analysis

The pharmacokinetic (PK) parameters of the total ezetimibe, free ezetimibe, rosuvastatin, telmisartan, and amlodipine were calculated via the noncompartmental method using WinNonlin 7.0 (Certara USA, Princeton, New Jersey). The primary PK parameters included the maximum plasma concentration at steady state (C max,ss ) and the area under the time-concentration curve within a dosing interval at steady state (AUC tau,ss ) of each component. The AUC tau,ss was calculated using the linear trapezoidal method for the ascending concentrations and the log trapezoidal method for the descending concentrations. The time to achieve C max (T max,ss ), t 1/2 at steady state (t 1/2,ss ), apparent clearance at steady state (CL ss /F), and apparent volume of distribution at steady state (V d,ss /F) were also evaluated.

Pharmacokinetics of Forsythin and Metabolites

The PK parameters were calculated with WinNonlin 7.0 (Certara, Princeton, NJ, USA) using noncompartmental analysis. As the PK parameters of the SAD study were previously reported, calculations of PK parameters for the MAD study and the food effect study were conducted in this report. In the MAD study, PK parameters of forsythin and its main metabolites M2 and M7, including Cmax, Tmax, AUC0–t, AUC0–∞, T1/2, CL/F, VZ/F, Cmin,ss, Cavg,ss, AUCss, drug fluctuation coefficient (DF) and accumulation ratio (Racc) were estimated. The Racc at steady-state after multiple doses was calculated as follows: (AUC0–8 or Cmax on day 5)/(AUC0–8 or Cmax on day 1). Steady-state status was determined by visual inspection of trough concentrations () on days 3, 4 and 5.

Pharmacokinetics of Antibody-Drug Conjugate

Serum samples to assess pharmacokinetics (PK) were required for the first six evaluable patients < 15 years. Samples were obtained before treatment; at the end of infusion; at 1, 2, 4, 8, and 24 hours post-infusion on day 1; and 4, 7, and 21 days postinfusion. GV was quantitated in total antibody (TA) and antibody-drug conjugate (ADC) using enzyme-linked immunosorbent assays (ELISA). Free MMAE was quantified using liquid chromatography/mass spectrometry. All assays were described previously by Ott et al. [10 (link)].
Noncompartmental analysis was performed with WinNonlin 7.0 (Certara USA, Inc.) using nominal dosing for ADC and TA (1.9 mg/kg), total MMAE per dose was based on molar coupling ratio in drug product, and respective molecular weights of GV (150 kD) and auristatin E (718 Da). Infusion models were used for TA and ADC and an extravascular model was used for free MMAE. Exposure (Cmax, AUC0–3w) was determined for ADC and TA by linear trapezoidal approximation. Terminal elimination half-life was determined by least squares fitting of experimental concentrations in the terminal phase for TA and ADC analytes, as well as for free MMAE.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
