Patients assigned to arm A, will receive acalabrutinib as one capsule of 100 mg orally twice daily on a continuos schedule until disease progression, unacceptable toxicity or early withdrawal.

Patients assigned to arm B, will receive standard of care for the management of early Binet stage A patients "clinical observation (watch & wait)" until disease progression or early withdrawal.

Study to Investigate the Use of Acalabrutinib in the Treatment of Patients With Chronic Lymphocytic Leukemia

Phase III Randomized Study to Investigate the Use of Acalabrutinib in the Treatment of Patients With Early Stage CLL With High Risk of Early Disease Progression

EFS is defined as the time between the date of randomization and time point of symptomatic disease progression with treatment indication according to the iwCLL-Guidelines, initiation of subsequent treatment for CLL or death by any cause, whichever occurs first.

Time between the date of randomization and progression of disease or death from any cause, whichever occurs first.

Time between the date of randomization and death from may cause.

Time from randomization until the date of initiation of subsequent treatment for CLL or death from any cause.

Is defined as the proportion of patients who achieve a CR (Complete Remission), CRi (CR with incomplete bone marrow recovery), nPR (nodular Partial Remission) or PR (Partial Response) over the course of the study. Patients who achieve a PR with lymphocytosis will be included in the ORR. The rate of MRD-negative disease (MRD: Minimal Residual Disease) will also be calculated. The IWCLL guidelines (Hallek, 2018) will be used to measure response in CLL.

Arm A (65 patients): Patients assigned to arm A, will receive acalabrutinib as one capsule of 100 mg orally twice daily on a continuos schedule until disease progression, unacceptable toxicity or early withdrawal.
Arm B (65 patients): Patients assigned to arm B, will remain on the w&w approach until disease progression or early withdrawal.

Acute Myeloid Leukemia

All PET/CT scans were performed using a hybrid PET/CT scanner (Gemini TF 64 with Astonish TF, Philips). F-18 FLT (2.96 MBq/kg) in 2-5 mL of normal saline was injected intravenously. One hour after FLT injection, CT began at the vertex and progressed to the upper thigh (120 kVp, 100 mA and 4 mm slice thickness). PET emission data were acquired immediately for 1 min at each bed position followed. The CT data were used for attenuation correction. Images were reconstructed using a standard ordered-subset expectation maximization algorithm with 3 iterations and 33 subsets.

Approximately 40 patients (adults and children) suffering from IBD will be enrolled.

15 ml peripheral blood will be obtained from all participants.
