Study Details

The purpose of this study is to characterize safety and to determine the Recommended Phase 2 Dose (RP2D\[s\]) and optimal dosing schedule(s) of JNJ-88549968 in part 1 (Dose Escalation); to characterize the safety of JNJ- 88549968 at RP2D(s) in part 2 (Cohort Expansion). For U.S. sites: the purpose of this study is to characterize the safety and to determine the RP2D(s) and optimal dosing schedule(s) of JNJ-88549968 in Part 1 and part 1b (Dose Escalation), and to characterize the safety of JNJ-88549968 at the RP2D(s) in Part 2 and part 2b (Cohort Expansion), when given as monotherapy in essential thrombocythemia (ET) or myelofibrosis (MF), and with ruxolitinib or momelotinib in MF only.

Arms

  • Experimental: Dose Escalation (Part 1), Dose Expansion (Part 2) and Part 1b (US only), Part 2b (US only)
    In dose escalation (Part 1), participants will receive JNJ-88549968. For myelofibrosis (MF) participants only, the study will explore a Phase 1b cohort in which the janus kinase (JAK) inhibitor ruxolitinib or momelotinib is started in combination with JNJ-88549968. The dose will be escalated sequentially to determine the recommended phase 2 dose (RP2D) and optimal dosing schedule (s) based on safety, pharmacokinetic, pharmacodynamic, and preliminary assessment of efficacy across several dose regimens. In dose expansion (Part 2, Part 2b \[US only\]), participants will receive JNJ-88549968 at the RP2D regimen(s) determined in dose escalation (Part 1, Part 1b \[US only\]).

Primary Outcome Measure

Part 1, Part 1b (US Only): Number of Participants With Dose Limiting Toxicity (DLT) [ Time Frame: Approximately up to 35 days after first dose of study treatment ]
