An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention.

Population: The analysis population included all participants who received ≥1 dose of MK-2060 and who complied with the protocol sufficiently to ensure that the data are likely to exhibit the effects of treatment according to the underlying scientific model.

The AUC0-168 was defined as the area under the concentration-time curve of MK-2060 in plasma from time zero to 168 hours after administration. The Week 1 value is the extrapolated value using data up to 48 hours postdose Day 1, with the "Partial area" option in WinNonlin software using a Start time of 0 hours and an End time of 168 hours. Week 2 value included data for Day 8: predose, and 1, 12, 24, 48, 96, and 168 hours postdose.
