Clinical Outcomes of Chronic Lymphocytic Leukemia (CCL) and Mantle Cell Lymphoma (MCL) Participants Treated With Ibrutinib: A Medical Chart Review From India

ORR is defined as achievement of complete response (CR) or partial response (PR) per International Workshop on Chronic Lymphocytic Leukemia (IWCLL) 2008 guidelines for Chronic Lymphocytic Leukemia (CLL) and Mantle-cell Lymphoma (MCL). CR is defined as resolution of enlarged lymph nodes, spleen and liver; normalization of blood counts (neutrophils, hemoglobin, platelets); no residual CLL/MCL detectable in the bone marrow. PR is defined as 50 percent (%) or more reduction in size of enlarged lymph nodes, liver or spleen; 50% or more improvement of blood counts; 50% or more reduction in the blood lymphocyte count.

Time to progression will be reported for the observed participants receiving ibrutinib. TTP is defined as the period from study entry until objective disease progression (time from the date of randomization until disease progression or death due to progression, whichever occur first).

Percentage of participants with CR will be reported. CR is defined as resolution of enlarged lymph nodes, spleen and liver; normalization of blood counts (neutrophils, hemoglobin, platelets); no residual CLL/MCL detectable in the bone marrow.

Percentage of participants with PR will be reported. PR is defined as 50 percent (%) or more reduction in size of enlarged lymph nodes, liver or spleen; 50% or more improvement of blood counts; 50% or more reduction in the blood lymphocyte count.

Percentage of participants with SD will be reported. Participants who have not achieved a CR or a PR, and who have not exhibited progressive disease will be considered to have stable disease.

Percentage of participants with PD will be reported. PD is defined as 50% or more increase in lymph nodes or the appearance of new enlarged lymph nodes; 50% or more increase in the size of the spleen or liver; 50% or more increase in blood lymphocyte count.

Median time to response with ibrutinib in CLL and MCL participants will be reported. Time to response is defined as the time from start of ibrutinib therapy until objective response (CR or PR assessed by the investigator, based on physical examinations, CT scans, laboratory results, and bone marrow examinations, according to the modified 2008 IWCLL response criteria).

Change from baseline in blood hemoglobin level will be reported.

Change from baseline in blood platelet counts will be reported.

Number of participants, who progresses on at least one prior line of therapy, with response to ibrutinib will be reported.

Number of participants with hematological and non-hematological ADR will be reported. An adverse drug reaction (ADR) is defined as a response to a medicinal (investigational or non-investigational) product that is noxious and unintended. The phrase "response to a medicinal product" means that a causal relationship between a medicinal product and an adverse event is possible, probable or very likely.
