简要总结
This study is evaluating the safety, pharmacodynamics (PD), and efficacy of acalabrutinib and pembrolizumab in hematologic malignancies.
详细描述
This is a Phase 1b/2, open-label, nonrandomized study that will be conducted in 2 stages. In the first stage, Part 1 of the study will determine the safety and preliminary efficacy of acalabrutinib and pembrolizumab in a limited group of B-cell malignancies. In the second stage, Part 2 allows for possible expansion cohorts into a wider range of B-cell malignancies, and Part 3 will evaluate the combination in subjects with myelofibrosis (MF).

- •ANC ≥ 0.5 x 10^9/L or platelet count ≥ 50 x 10^9/L unless due to disease involvement in the bone marrow.
排除标准
- •A life-threatening illness, medical condition or organ system dysfunction which, in the investigator's opinion, could compromise the subject's safety, interfere with the absorption or metabolism of study drugs, or put the study outcomes at undue risk.
- •Central nervous system (CNS) involvement by lymphoma/leukemia

- •Total bilirubin > 1.5 x ULN; and aspartate aminotransferase (AST) or alanine aminotransferase (ALT) > 3.0 x ULN.
- •Estimated creatinine clearance of < 30 mL/min, calculated using the formula of Cockcroft and Gault (140-Age) • Mass (kg)/(72 • creatinine mg/dL); multiply by 0.85 if female.
研究组 & 干预措施
Acalabrutinib plus Pembrolizumab
A nonrandomized study that will be conducted in 2 stages. In the first stage, (Safety), subjects will receive Acalabrutinib Dose A orally administered (PO) twice daily (BID) in combination with Pembrolizumab Dose B administered every 3 weeks (Q3W).
The second stage was an expansion of Cohorts with the same dose regimen as the first stage. An additional expansion in subjects with Myelofibrosis was planned but not conducted.
干预措施: Pembrolizumab (Drug)

结局指标
主要结局
Number of Participants With Grade 3-4 Adverse Events
时间窗: 104 weeks
Severity of AEs was graded using the Common Terminology Criteria for Adverse Events (CTCAE), version 4.03
Number of Participants With Any Study-Drug Related AE
时间窗: 104 weeks
Study drug-related AEs were those assessed by investigator as related to study treatment.
Number of Participants With Grade 3-4 Study-Drug Related AE
时间窗: 104 weeks
The severity of the AEs was assessed by NCI CTCAE Version 4.03 or higher. Drug-related AEs were those assessed by investigator as related to study treatment.
Number of Participants With Grade 5 Study-Drug Related AE
时间窗: 104 weeks
Grade 5 (fatal) AEs assessed by investigator as related to study treatment.
Number of Participants With Any Grade 5 Study Drug-Related SAE

Grade 5 AEs were fatal events. Serious AEs were those that resulted in death, were life-threatening, required or prolonged in-patient hospitalization, resulted in persistent or significant disability/incapacity, resulted in a congenital anomaly/birth defect in a neonate/infant born to a mother exposed to the investigational product, or were considered a significant medical event by the investigator based on medical judgment. Drug-related AEs were those assessed by investigator as related to study treatment.
Number of Participants With Treatment Emergent Adverse Events (AEs)
时间窗: 104 weeks
Treatment-emergent AEs were defined as those events that occurred on or after the first dose of study drug, through the treatment phase, and within 30 days following the last dose of study drug.
