To Evaluate the Safety, Tolerability and Pharmacokinetics of CT-P63 in Healthy Subjects

CT-P63 is a monoclonal antibody targeted against SARS-CoV-2 spike RBD as a treatment for SARS CoV 2 infection. CT-P63 is currently being developed by the Sponsor as a potential treatment for SARS-CoV-2 infection. In this study, safety, tolerability, and pharmacokinetics of CT-P63 will be evaluated in healthy subjects.

[Inclusion Criteria]

Each subject must meet all of the following criteria to be randomized in this study:

• Subject is a healthy male or female subject, aged between 18 to 60 years (both inclusive). Health is defined as no clinically relevant abnormalities identified by Investigator's decision based on a detailed medical history, full physical examination, including blood pressure, heart rate, respiratory rate, and body temperature measurements, 12-lead electrocardiogram (ECG) and clinical laboratory tests prior to the study drug administration.
• Subject with a body weight of ≥ 50 kg and a body mass index between 18.0 and 29.9 kg/m2 (both inclusive).
• Subject is able to understand and to comply with protocol requirements, instructions, and restrictions.

[Exclusion Criteria]

A Subject meeting any of the following criteria will be excluded from the study:

• Subject has a medical history or current presence of disease including one or more of the following(s):

• History of or current allergic reaction such as asthma, urticaria, angioedema, and eczematous dermatitis considered as clinically significant in the Investigator's opinion or hypersensitivity including known or suspected clinically relevant drug hypersensitivity to any monoclonal antibody or any component of study drug
• History of or current medical condition including gastrointestinal, renal, endocrine, neurologic, autoimmune, hepatic, hematological metabolic (including known diabetes mellitus), cardiovascular, or psychiatric condition classed as clinically significant by the Investigator

• History of an illness within 28 days prior to the study drug administration that is identified as clinically significant by the Investigator or requires hospitalization
• History of surgical intervention or an operation within 28 days prior to the study drug administration or plans to have a surgical procedure during the study period
• Subject had a history of or concurrent use of medications including any prior therapy of following(s):

• Any vaccination within 4 weeks prior to the study drug administration. For SARS-CoV-2 vaccine, subject who received any investigational or approved SARS-CoV-2 vaccine cannot be enrolled, regardless of the timing of administration
• Treatment with any monoclonal antibody, fusion protein, or blood transfusion within 6 months or 5 half lives (which is longer) prior to the study drug administration or current use of biologics
• Prescription medication (excluding hormonal birth control), over-the-counter drug, dietary supplements or herbal remedies within 7 days or 5 half-lives (whichever is longer) prior to the study drug administration
