Une étude du JNJ-88549968 pour le traitement des néoplasmes myéloprolifératifs mutés par la calréticuline (CALR)

2 novembre 2026 mis à jour par: Janssen Research & Development, LLC

Une première étude chez l'homme sur l'innocuité, la pharmacocinétique et la pharmacodynamique du JNJ-88549968, un anticorps bispécifique redirigeant les lymphocytes T pour les néoplasmes myéloprolifératifs mutés par CALR

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.

Armes et Interventions

Groupe de participants / Bras
Intervention / Traitement
Expérimental: 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. Additional Cohorts may be added to assess different formulation or delivery methods. 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]).

JNJ-88549968 will be administered.

For US sites: Ruxolitinib will be administered for participants with MF only.

For US sites: Momelotinib will be administered for participants with MF only.

Description de la mesure
Délai
Part 1, Part 1b (US Only): Number of Participants With Dose Limiting Toxicity (DLT)
Délai: Approximately up to 35 days after first dose of study treatment

Number of participants with DLT will be reported. The DLTs are specific adverse events and are defined as any of the following: high grade non-hematologic toxicity, or hematologic toxicity. For US only: A DLT is any adverse event attributed to study treatment that meets the criteria for severity and duration and that occurs during the evaluation periods unless it can be incontrovertibly attributed to disease or other extraneous cause such as an accident.

Approximately up to 35 days after first dose of study treatment
Part 1, 2, Part 1b (US Only), Part 2b (US Only): Number of Participants with Adverse Events (AEs)
Délai: Up to 2 years

An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study.

Up to 2 years
Part 1, 2, Part 1b (US Only), Part 2b (US Only): Number of Participants with Adverse Events (AEs) by Severity
Délai: Up to 2 years

An adverse event is any untoward medical occurrence in a clinical study participant that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study. Severity will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0. Severity scale ranges from grade 1 (mild) to grade 5 (death). Grade 1= mild, Grade 2= moderate, Grade 3= severe, Grade 4= life-threatening and Grade 5= death related to adverse event. Cytokine release syndrome (CRS) and associated neurologic toxicity events (immune effector cell-associated neurotoxicity syndrome events [ICANS]) will be graded according to the American Society for Transplantation and Cellular Therapy (ASTCT) guidelines.
