NameTypeDescription
VRDN-003DRUGVRDN-003 is an investigational, subcutaneously administered, humanized monoclonal antibody directed against the Insulin-like Growth Factor-1 receptor (IGF-1R).
AutoinjectorDEVICEThe autoinjector is a single-dose, disposable, ready-to-use delivery device
PlaceboDRUGAll participants will receive the same number of injections to maintain masking. Masking will be maintained by the use of placebo injections that appear identical to VRDN-003 injections.
