Dose-Limiting Toxicities (DLT) were monitored/assessed from the time of first drug administration through 28 days after starting the trial treatment.

What was measured

DLT is defined as any one of the following adverse events, possibly attributable to study drugs, that occur within 28 days of the human papillomavirus (HPV) vaccine monotherapy or 28 days of starting the HPV vaccine + M7824 (MSB0011359C) combination therapy: any grade 3 or higher bleeding episode requiring blood transfusion(s); Any Grade 4 or \> adverse drug reactions (ADRs) as defined by the Common Terminology Criteria for Adverse Events (CTCAE) v5.0 and assessed as possibly related to any agent by the Investigator, except for laboratory values that are asymptomatic or resolve to Grade ≤ 1 or baseline grade within 7 days without medical intervention; discontinuation any Grade 3 ADRs possibly attributed to any agent except for any of the following: Grade 3 flu-like symptoms or fever, as well as associated symptoms of fatigue, headaches, nausea, emesis which can be controlled with conservative medical management. See Protocol for details.

Analysis population: DLTs evaluable for 3 participants enrolled in each dose level in Arm 1A and 6 participants in Arm 1B of phase I part of the study.
