Preclinical Pharmacokinetics Evaluation of Anti-heparin-binding EGF-like Growth Factor (HB-EGF) Monoclonal Antibody Using Cynomolgus Monkeys via (89)Zr-immuno-PET Study and the Determination of Drug Concentrations in Serum and Cerebrospinal Fluid.
Article in Pharmaceutical research, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeHeparin-binding EGF-like growth factor (HB-EGF) is a member of the EGF family and is an important therapeutic target in some types of human cancers. KHK2866 is a humanized anti-HB-EGF monoclonal antibody IgG that neutralizes HB-EGF activity by inhibiting the binding of HB-EGF to its receptors. The phase I study of KHK2866 was discontinued because of neuropsychiatric toxicity. In this study, the pharmacokinetics of KHK2866 was evaluated by (89)Zr-immuno-PET study and the determination of drug concentrations in serum and cerebrospinal fluid using cynomolgus monkeys was performed in order to predict neurotoxicity in a reverse-translational manner.
methodsKHK2866 was radiolabeled with (89)Zr for preclinical evaluations in normal cynomolgus monkeys and its distribution was analyzed. Furthermore, as a separate study, KHK2866 concentrations in serum and cerebrospinal fluid were determined after administration of a single dose.
resultsPET studies with monkeys revealed (89)Zr-KHK2866 accumulation in the liver, spleen and joints of multiple parts, but not in brain. In addition, the pharmacokinetic analyses in serum and CSF demonstrated a low penetration of KHK2866 into the brain.
conclusionsThese studies indicate the difficulty of prediction for neuropsychiatric toxicity of monoclonal antibodies in human by means of pharmacokinetic evaluations using cynomolgus monkeys.
