About
This study will be a 2-part, open-label, single-center relative bioavailability, PPI effect, food-effect and particle size effect randomized crossover study of acalabrutinib tablets in healthy subjects (males or females). The study will be divided in 2 study parts; following a review of the safety and Pharmacokinetics (PK) data from Part 1, the study is planned to be continued with Part 2.
Full description
The study will be divided in 2 study parts; Part 1 of this study will be an open-label, 3-treatment-period, 4-treatment, single-center relative bioavailability, PPI effect, and food-effect randomized crossover study of a new acalabrutinib tablet in healthy subjects (males or females).
The relative bioavailability part of Study Part 1 is designed to investigate the PK of the acalabrutinib tablet compared with the PK of acalabrutinib capsule, when administered as a single dose with water under the fasted condition (>10 hours). The PPI effect part of Study Part 1 is designed to compare the PK of acalabrutinib tablet with or without coadministration of the PPI rabeprazole. The food-effect part of Study Part 1 is designed to compare the PK of acalabrutinib tablet under fed and fasted conditions. For each subject, a SmartPill will be administered with 120 mL of still water followed immediately by a single oral dose of acalabrutinib tablet (Treatment B, C or D) or acalabrutinib capsule (Treatment A) administered with 120 mL of still water.
Study Part 1 will comprise:
- A screening period of maximum 28 days;
- Three treatment periods during which subjects will be resident from prior to the evening meal the night before dosing with Investigational medicinal product (IMP) (Day -1) until at least 48 hours after dosing; discharged on the morning of Day 3; and
- A Follow-up Visit within 7 to 10 days. There will be a minimum washout period of at least 7 days between each acalabrutinib administration.
A decision to continue with Study Part 2 will be made following a review of the preliminary data for relative bioavailability (acalabrutinib tablet versus acalabrutinib capsule), food effect, PPI effect, and safety observed in Part 1.
Part 2 of this study will be an open-label, 4-treatment-period, 4-treatment, single-center relative bioavailability, randomized crossover study to determine the effect of particle size on the PK of a single dose of acalabrutinib tablet in healthy subjects (males or females).
This relative bioavailability study is designed to investigate the PK of acalabrutinib tablets with various drug substance particle size distributions and the PK of acalabrutinib solution at a single oral dose of 100 mg under the fasted condition (>10 hours).
Study Part 2 will comprise:
- A screening period of maximum 28 days;
- Four treatment periods during which subjects will be resident prior to the evening meal the night before dosing with IMP (Day -1) until at least 48 hours after dosing; discharged on the morning of Day 3; and
- A Follow-up Visit within 7 to 10 days. There will be a minimum washout period of at least 3 days between each acalabrutinib administration.

Exclusion criteria
-
History of any clinically significant disease or disorder which, in the opinion of the Principal Investigator (PI), may either put the volunteer at risk because of participation in the study, or influence the results or the volunteer's ability to participate in the study.
-
History or presence of gastrointestinal (GI), hepatic or renal disease, or any other condition known to interfere with absorption, distribution, metabolism, or excretion of drugs.
-
Evidence of ongoing systemic bacterial, fungal, or viral infection (including upper respiratory tract infections).
-
Any clinically significant illness, medical/surgical procedure, or trauma within 30 days of the first administration of IMP.
-
Any clinically significant abnormalities in clinical chemistry, hematology, coagulation, or urinalysis results, at screening and first admission to the study unit (first treatment period) as judged by the PI, and defined as: (1) Serum Alanine aminotransferase (ALT), Aspartate aminotransferase (AST), alkaline phosphatase (ALP), and serum bilirubin (total and direct)
> Upper limit of normal (ULN). (2) Hemoglobin < ULN.
-
Any clinically significant abnormal findings in vital signs at screening and first admission to the study unit (first treatment period), as judged by the PI.
-
Any clinically significant abnormalities on 12-lead ECG at screening and first admission to the study unit (first treatment period), as judged by the PI.
-
Any positive result on screening for serum hepatitis B surface antigen, hepatitis B core antibody (anti-HBc), hepatitis C antibody, and HIV antibody.
-
Known or suspected history of drug abuse, as judged by the PI.
-
Has received another new chemical entity (defined as a compound which has not been approved for marketing) within 90 days of the first administration of IMP in this study.
The period of exclusion begins 90 days after the final dose or 30 days after the last visitwhichever is the longest.
-
Plasma donation within 30 days of screening or any blood donation/loss more than 500 mL during the 90 days prior to screening.
-
