Official title

A Phase 1 Study in Healthy Subjects to Evaluate the Safety and Pharmacokinetics of a Human Monoclonal Antibody (2217LS) Against Borrelia Burgdorferi (B. Burgdorferi) Outer Surface Protein A (OspA)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This is a research study of the investigational drug 2217LS in healthy volunteers. Investigational means 2217LS is a new drug that has not been approved for the treatment of any disease. 2217LS is human antibody designed to provide protection from Lyme disease. Lyme disease is a disease carried by infected ticks and can cause the infection to spread to the joints, heart and nervous system in humans. This is the first time 2217LS will be given to humans. This is not a study of how well 2217LS works against Lyme disease. The only purposes of this study are to: 1) Learn about the safety and tolerability of a subcutaneous (SC \[under the skin\]) injection of 2217LS when administered to healthy volunteers. 2) Find out how much 2217LS is in the blood of healthy volunteers after receiving 2217LS SC. In this study, groups of healthy volunteers will be given different doses of 2217LS by SC injection. Volunteers will stay in the study unit for a total of 4 overnights. The planned duration of participation is up to 14 months. Study personnel will monitor their safety using standard procedures like physical examinations, electrocardiograms, questions about possible side effects, blood and urine tests. The amount of 2217LS in their blood will also be measured.
