Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Dose Escalation

Participants with essential thrombocythemia (ET) and myelofibrosis (MF) will receive VAC85135 target dose intramuscular (IM) injection in the safety lead-in cohort (Cohort 0). Participants in subsequent cohorts will receive VAC85135 target dose IM injection along with ipilimumab intravenous (IV) infusion. Ipilimumab dose may be escalated based on dose limiting toxicity (DLT) observations.

Group Type EXPERIMENTAL
