    Description

    Ceritinib (LDK378) is a selective, orally bioavailable, and ATP-competitive ALK tyrosine kinase inhibitor with an IC50 of 200 pM. Ceritinib (LDK378) also inhibits IGF-1R, InsR, and STK22D with IC50 values of 8, 7, and 23 nM, respectively. Ceritinib (LDK378) shows great antitumor potency[1][2].

    IC50 & Target

    IC50: 0.2 nM (ALK), 7 nM (InsR), 8 nM (IGF-1R), 23 nM (STK22D), 60 nM (FLT3), 260 nM (FGFR2)[1]

    In Vitro

    Ceritinib (LDK378) also inhibits RET (IC50=400 nM), FGFR3 (IC50=430 nM), LCK (IC50=560 nM), JAK2 (IC50=610 nM), Aurora (IC50=660 nM), LYN (50=840 nM), EGFR (IC50=900 nM), and FGFR4 (IC50=950 nM)[1].
    Ceritinib (LDK378) retains high potency against the ALK enzymatic activity with an IC50 value of 200 pM and shows only strong inhibition against IGF-1R, InsR, and STK22D out of a panel of 46 kinases with a minimum selectivity of 70-fold. In Ba/F3 cells transfected with various kinases, Ceritinib inhibits ALK activity with an IC50 value of 40.7 nM and had IC50 values of >100 nM against all other kinases tested. Ceritinib (LDK378) shows potent antiproliferative activity with an IC50 value of 22.8 nM in Karpas 299 human non-Hodgkin’s Ki-positive large cell lymphoma carrying the NPM-ALK fusion gene and 26 nM in Ba/F3 cells transfected with the NPM-ALK fusion gene. Ceritinib also shows good selectivity over wild-type Ba/F3 cells (IC50>2 μM) and Ba/F3 cells transfected with Tel-InsR gene (IC50=320 nM)[2].

    In Vivo

    Ceritinib (LDK378) has an excellent pharmacokinetics profile in rodents and non-rodents with an oral bioavailability of >50%. Ceritinib demonstrates dose-dependent tumor growth inhibition and achieved partial tumor regression in the Karpas 299 rat xenograft model with daily administration but is capable of achieving complete tumor regression in the H2228 NSCLC rat xenograft model, which carries the EML4-ALK fusion gene. In both models, Ceritinib (LDK378) is well tolerated in animals. Ceritinib (LDK378) is further assessed for its ADME profile and is found to have a relatively good metabolic stability in liver microsomes, modest CYP3A4 inhibition, some hERG inhibition with an IC50 value of 46 μM in hERG patch clamp experiments, but no evidence of QTc prolongation in both dog and monkey telemetry studies[2].

    In Vivo:

    Select the appropriate dissolution method based on your experimental animal and administration route.

    For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
    To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
    The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

    • Protocol 1

      Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

      Solubility: ≥ 0.5 mg/mL (0.90 mM); Clear solution

      This protocol yields a clear solution of ≥ 0.5 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

      Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
    • Protocol 2

      Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

      Solubility: ≥ 0.5 mg/mL (0.90 mM); Clear solution

      This protocol yields a clear solution of ≥ 0.5 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

      Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

    Animal Administration
    [1]

    In vivo PK studies are conducted in mice, rats, dogs, and cynomolgus monkeys. Ceritinib (LDK378) (HCl salt) is administered to male Balb/c mice intravenously via tail vein at 5 mg/kg (n=3) and orally via gavage at 20 mg/kg (n=3). By use of the same formulation, Ceritinib (LDK378) (HCl salt) is dosed to Sprague-Dawley rats intravenously via the tail vein at 3 mg/kg (n=3) and orally via gavage at 10 mg/kg (n=3). Blood samples are collected serially at scheduled times over 24 h after dosing. Male beagle dogs receive a single intravenous (n=2) or oral (n=3) dose of Ceritinib (phosphate salt) as an intravenous solution at 5 mg/kg and an oral suspension at 20 mg/kg, respectively. Male cynomologus monkeys receive single intravenous (n=2) or oral (n=3) dose of Ceritinib (free base) as an intravenous solution at 5 mg/kg and an oral suspension at 60 mg/kg, respectively. Blood samples for plasma are collected at prescheduled times over 144 h after dosing[1].

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
