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.

Determine if the immunogenicity of oral typhoid can be enhanced in children by introducing zinc supplementation: Our recent studies on the interactions of oral cholera vaccine with breast milk and zinc provide some basis for improving immunogenicity, but additional work is needed to improve many of the oral vaccines. In this study we also plan to evaluate if the immune response to Cholera and Vivotif can be enhanced by supplementation with zinc using methods described earlier. We would like to study children, 2-5 years of age for this purpose.

There is a high burden of enteric parasites in the gut of people living in densely populated areas of less developed countries. The effect of concurrent parasitic infestations on immune responses has not been studied widely, although it is an area of utmost importance for natural protection as well as vaccine immuno-prophylaxis. In this study we plan to determine the impact of pretreatment with antiparasitic agents (albendazole and secnidazole) on the immunogenicity of the oral cholera and typhoid vaccines in children, 2-5 years of age

In this study, we aim to evaluate if immunogenicity of the oral cholera vaccine is modified in children living in a high arsenic contaminated area in Bangladesh. The plan is to study children 2-5 year old living in Shahrasti thana near Matlab where the tubewell water is highly contaminated with arsenic and this study will not be randomized double-blind, and compare their responses with responses of age matched children living in arsenic free area, such as in Mirpur area of Dhaka city. We only plan to study the effect of Dukoral vaccinees since this vaccine has been widely studied in Bangladesh. If an impact of arsenic is seen on immune response to this vaccine, future studies could be done with other vaccines including Vivotif.
