The adverse reaction (all grades) occurring in more than 5% of participants was headache, which occurred in 6% and 4% of patients who received HOVILPRI and investigator’s choice, respectively.1

A lower rate of drug-related treatment-emergent adverse events (TEAEs) was reported in participants who were treated with HOVILPRI (22%) compared with participants who were treated with investigator's choice (54%). Discontinuations due to drug-related TEAEs occurred in 2% and 20% of participants, respectively.1
