Tanruprubart
Based on 5 publication(s) in Google Scholar
Tanruprubart (ANX005) is a C1q inhibitor and C1q depleter. Tanruprubart is a human antibody expressed in CHO cells, with huIgG1 heavy chains and huκ light chains, and its predicted molecular weight (MW) is 145 kDa. For the isotype control of Tanruprubart, refer to Human IgG4 kappa, Isotype Control (HY-P99003). The IC50 of Tanruprubart is 346 ng/mL for humans and 259 ng/mL for rats; its EC50 is 3.8 ng/mL for humans, 5.2 ng/mL for rats, and 9.9 ng/mL for mice. Tanruprubart is applicable to the research of Guillain-Barré syndrome and Alzheimer's disease.

Tanruprubart (ANX005) (Titered concentrations) binds with high, comparable affinity to serum-derived C1q from human, cynomolgus monkey, rhesus monkey, dog, and rat, has lower affinity for mouse C1q, and does not bind rabbit C1q[1].
Tanruprubart (Titered concentrations; 1 h) potently inhibits classical complement-mediated hemolysis in human, cynomolgus monkey, rhesus monkey, dog, and rat serum, with an average IC50 of ~350 ng/mL, and does not inhibit hemolysis in rabbit serum[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Tanruprubart (ANX005) (10-200 mg/kg; i.v.; single bolus dose; once weekly; 4 weeks) administered to cynomolgus monkeys (as single doses or weekly doses for 4 weeks) produces dose-dependent serum and CSF exposures, fully depletes free serum C1q and inhibits complement-mediated hemolysis at measurable reagent levels, fully occupies CSF C1q at higher doses, and shows no treatment-related toxicity at doses up to 200 mg/kg, resulting in a no observed adverse effect level (NOAEL) of 100 mg/kg[1].

Animal Model:Sprague Dawley rats (male and female, young adult, 8-9 weeks old)[1]
-
Dosage:10 mg/kg; 50 mg/kg; 100 mg/kg; 200 mg/kg
-
Administration:i.v.; once weekly; 4 weeks
-
Result:Depleted free C1q in rat serum at measurable reagent levels.\nShowed dose-proportional increases in serum Cmax; AUC increased greater than dose-proportionally between lower doses, and dose-proportionally between 100 and 200 mg/kg.\nIncreased mean CSF concentrations in a greater-than-dose-proportional manner, with CSF levels representing 0.1% to 0.2% of serum levels on days 38 and 50 of the GLP study.\nExhibited no treatment-related changes in clinical signs, body weight, food consumption, clinical pathology, gross pathology, organ weight, or histopathology at any dose tested.\nAchieved a no observed adverse effect level (NOAEL) of 200 mg/kg.

Result:Depleted free C1q in monkey serum at measurable reagent levels, with free C1q returning to baseline only when reagent levels dropped below detection.\nInhibited ex vivo complement-mediated hemolysis completely at measurable reagent serum levels, with hemolysis activity returning to baseline when reagent levels declined.\nShowed dose-dependent increases in serum concentrations, with trough levels accumulating over weekly doses in the 50, 100, and 200 mg/kg groups (excluding animals with anti-drug antibody responses).\nIncreased mean CSF concentrations with dose, with CSF levels representing 0.04% to 0.11% of serum levels in the non-GLP study, and 0.02% to 0.13% of serum levels in the GLP study on day 29; these CSF levels fully occupied C1q in the CSF at 100 and 200 mg/kg doses on day 29.\nExhibited no treatment-related changes in clinical signs, body weight, food consumption, clinical pathology, gross pathology, organ weight, histopathology, ophthalmic findings, neurologic exams, vital signs, or electrocardiograms at any dose tested.\nAchieved a no observed adverse effect level (NOAEL) of 200 mg/kg.
