COVID-19 Study Assessing the Safety and Tolerability of Co-Formulated Anti-Spike (S) SARS-CoV-2 Monoclonal Antibodies (Casirivimab+Imdevimab) in Adult Volunteers

• Status: Not yet recruiting
• Trial end date: 2022-05-19
• Target enrollment: 0
• Participant gender: All

Summary

The primary objective of the study is to assess the safety and tolerability of co-formulated subcutaneous (SC) and intravenous (IV) casirivimab+imdevimab

The secondary objectives of the study are to:

• Explore variability in the drug concentration profiles of casirivimab and imdevimab after co-formulated subcutaneous (SC) or intravenous (IV) administration

• Characterize the immunogenicity of casirivimab and imdevimab in serum over time

• Phase: Phase 1
• Accepts Healthy Volunteers?: Accepts Healthy Volunteers

3. Weighs between ≥60 kg and ≤100 kg at the time of screening

4. Has SARS-CoV-2-negative reverse-transcriptase polymerase chain reaction (RT-PCR) from a sample collected ≤72 hours prior to randomization, using local assay and sample collection and assay standards

3. Prior use of casirivimab+imdevimab at any time prior to randomization

4. Prior, current, or planned use during the study of any of the following treatments:

COVID-19 convalescent plasma, other monoclonal antibodies against SARS-CoV-2 (eg, bamlanivimab and etesevimab, sotrovimab), intravenous immunoglobulin (any indication), or any other investigational, authorized, or approved agent intended for COVID-19 treatment or prevention (with the exception of COVID-19 vaccines)

5. Treatment with another investigational drug in the last 30 days or within 5 half-lives of the investigational drug, whichever is longer, prior to screening

6. Body mass index (BMI) ≥28 kg/m2

7. Medically-attended acute illness, systemic antibiotics use, or hospitalization for any reason within 30 days prior to screening

9. Uncontrolled hypertension, in the opinion of the investigator

10. History of heart failure hospitalization, diagnosis of a myocardial infarction, stroke, transient ischemic attack, unstable angina, percutaneous or surgical revascularization procedure (coronary, carotid, or peripheral vascular), or intracardiac device placement (eg, pacemaker) within 12 months prior to screening

11. Cancer requiring treatment currently or in the past 5 years, except for non-melanoma skin cancer or cervical/anus in-situ

12. Is pregnant at screening
