MEDI-5884
MEDI-5884 (REG-101) is a humanized IgG4Pκ neutralizing monoclonal antibody targeting endothelial lipase (EL), with an IC50 of 1.3 nM and 1.7 nM against human and cynomolgus monkey EL, respectively; its Kd values for human and cynomolgus monkey EL are 4.1 nM and 1.6 nM, respectively. MEDI-5884 increases plasma levels of HDL-C, apolipoprotein A1 (ApoA1) and phospholipids, while causing a slight increase in LDL-C and apolipoprotein B (ApoB) levels. MEDI-5884 can be used in research related to cardiovascular diseases, coronary heart disease, coronary atherosclerosis and stable coronary artery disease.

Endothelial lipase
MEDI-5884 (0.5-30 mg/kg; s.c.; single dose) neutralizes endogenous endothelial lipase in cynomolgus monkeys, producing dose-dependent, sustained elevations in HDL-C, ApoA1, and phospholipids, with a twofold HDL-C increase maintained for 2 months at the 30 mg/kg dose[1].
MEDI-5884 (10 mg/kg; s.c.; two doses on day 28 and day 42) elevates HDL-C in cynomolgus monkeys pretreated with a PCSK9 inhibitor, while the associated LDL-C increase is mitigated[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:C57BL/6J (8-week-old male, adenoviral overexpression of human endothelial lipase to reduce endogenous HDL-C)[1]
-
Dosage:30 mg/kg
-
Administration:s.c.; single dose
-
Result:Prevented further reduction in HDL-C and restored HDL-C nearly to baseline concentrations (baseline ~100 mg/dl, day 4 after Ad-hEL ~50 mg/dl, day 5 after treatment ~75 mg/dl).
-
Animal Model:Macaca fascicularis (2 to 3 years old, male, 2.4 to 3.0 kg)[1]
-
Dosage:0.5 mg/kg; 6 mg/kg; 30 mg/kg
-
Administration:s.c.; single dose
-
Result:Increased plasma HDL-C, ApoA1, and phospholipids in a dose-dependent manner.
Achieved an approximate twofold increase in HDL-C within 2 weeks at 30 mg/kg, which persisted for 2 months.
Produced similar maximum HDL-C increase at 6 mg/kg, with HDL-C returning to baseline by study end.
Resulted in smaller HDL-C increase at 0.5 mg/kg, which returned to baseline within 3 weeks.
Caused smaller magnitude, dose-dependent increases in LDL-C and ApoB, with no clear effect on triglycerides.
-
Animal Model:Macaca fascicularis (2 to 3 years old, male, 2.4 to 3.0 kg, pretreated with PCSK9 inhibitor to lower LDL-C)[1]
-
Dosage:10 mg/kg
-
Administration:s.c.; two doses on day 28 and day 42
-
Result:Maintained ability to raise HDL-C to a similar degree as seen in monkeys without PCSK9 inhibitor pretreatment.
Blunted the magnitude of LDL-C increase relative to MEDI-5884 alone.
Changed ApoA1 and ApoB matching patterns of HDL-C and LDL-C, respectively.
