Cell experiment: |
HUVECs are grown on calibrated glass coverslips to a confluency of 80%. Subsequently, cells are incubated with 200 µg/mL Ustekinumab AlexaFluor488 and Briakinumab AlexaFluor594 for 20 min at 37°C, pH 7.3, washed three times, and chased in fresh medium for an additional 20 min before fixation. Antibodies are directly labeled. FcRn binding is quality controlled by SPR analysis. Cells are then counterstained with anti-FcRn monoclonal antibody DVN22, followed by anti-mouse secondary antibodies conjugated to AlexaFluor647. Imaging is performed on a Leica SP8 confocal microscope[2]. |

Ustekinumab (Stelara, CNTO 1275) is an anti-IL-12/IL-23 IgG1κ human monoclonal antibody used to treat psoriasis. MW=145.6 kDa.
The addition of Ustekinumab (UST) significantly inhibits T follicular helper (TFH) cell differentiation in vitro.[1]
Ustekinumab is generated via recombinant human IL-12 immunization of human Ig (hu-Ig) transgenic mice. Ustekinumab binds to the p40 subunit common to IL-12 and IL-23 and prevents their interaction with the IL-12 receptor β1 subunit of the IL-12 and IL-23 receptor complexes.[2]

Development and Translational Application of a Minimal Physiologically Based Pharmacokinetic Model for a Monoclonal Antibody against Interleukin 23 (IL-23) in IL-23-Induced Psoriasis-Like Mice
J Pharmacol Exp Ther 2018 Apr;365(1):140-155.PMID:29420255DOI:10.1124/jpet.117.244855
The interleukin (IL)-23/Th17/IL-17 immune pathway has been identified to play an important role in the pathogenesis of psoriasis. Many therapeutic proteins targeting IL-23 or IL-17 are currently under development for the treatment of psoriasis. In the present study, a mechanistic pharmacokinetics (PK)/pharmacodynamics (PD) study was conducted to assess the target-binding and disposition kinetics of a monoclonal antibody (mAb), CNTO 3723, and its soluble target, mouse IL-23, in an IL-23-induced psoriasis-like mouse model. A minimal physiologically based pharmacokinetic model with target-mediated drug disposition features was developed to quantitatively assess the kinetics and interrelationship between CNTO 3723 and exogenously administered, recombinant mouse IL-23 in both serum and lesional skin site. Furthermore, translational applications of the developed model were evaluated with incorporation of human PK for Ustekinumab, an anti-human IL-23/IL-12 mAb developed for treatment of psoriasis, and human disease pathophysiology information in psoriatic patients. The results agreed well with the observed clinical data for Ustekinumab. Our work provides an example on how mechanism-based PK/PD modeling can be applied during early drug discovery and how preclinical data can be used for human efficacious dose projection and guide decision making during early clinical development of therapeutic proteins.
