About
This is a first-in-human, open label, single dose, dose-escalation phase 1 study to evaluate the safety and pharmacokinetics of a combination of two highly neutralizing anti-SARS-CoV-2 mAbs targeting two distinct epitopes on the receptor protein binding domain (RBD) of the SARS-CoV-2 spike protein in healthy volunteers.
Full description
The study has a standard 3+3 phase 1 dose escalation design. Study participants will receive subcutaneous injections of C144-LS and C135-LS at 4ml (approximately 100mg of each antibody administered separately) or 8ml (approximately 200mg of each antibody administered separately), or sequential intravenous infusions of C144-LS and C135-LS, at one of three increasing dose levels (1.5 mg/kg, 5 mg/kg and 15 mg/kg of each antibody).
