Brief summary

The purpose of the study was to understand the effectiveness and safety of the study medicine called Inotuzumab ozogamicin (InO) in patients with B-cell ALL in whom the disease occurred again after the last treatment. This retrospective Study enroll adult patients who: * were CD22 positive (a molecule in the body that stops the over activity of the immune system) * Received only InO for the treatment of B-cell ALL that occurred again after the last treatment * were Philadelphia chromosome positive (which occurs because of changes in genes) * failed treatment with at least one Tyrosine Kinase Inhibitor (type of medicine that blocks the action of enzymes called tyrosine kinases which takes care of many cell functions, such as cell growth and division). The patient data except their personal details are collected from a hospital based electronic medical record in India. In this study the effectiveness and safety of InO will be studied after it was released to the market. To do that, the study aims to gather details of B-cell ALL patients from 7 -10 hospitals across India: * in whom the disease occurred again * or those who never showed any improvement to earlier treatments * now being treated with InO alone Around 55 patients who have taken InO are likely to be enrolled in the study. Then by using a statistical model and with all the information gathered, the safety and effectiveness of InO will be decided.

Survival Rate at 6 and 12 Months in Transplanted and Non-Transplanted Participants Who Achieved CR/CRi and MRD Negativity

Survival rate: percentage of participants in a study or treatment group who were still alive for a certain period of time after they were diagnosed with or started treatment for a disease. Negative MRD was defined as documented in medical records or (if unavailable in the records) as leukemic cells comprising \<1\*10\^-4 (\<0.01%) of bone marrow nucleated cells. MRD was assessed by multicolour flow cytometry. CR was defined as 5% bone marrow blasts, no evidence of disease in the bone marrow, and recovery of peripheral blood count (platelet count of \>100\*10\^9 cells/L and absolute neutrophil count of \>1\*10\^9 cells/L). CRi was defined as 5% bone marrow blasts and no evidence of disease in the bone marrow, but with incomplete recovery of peripheral blood count. In this outcome measure percentage of participants who had either CR or CRi with MRD negativity and survived at the end of 6 months and 12 months post initiation of InO treatment are reported on the basis of transplantation status.

Time frame: 6 and 12 months post initiation of InO treatment; data retrospectively collected from 08-Mar-2023 to 10-Jul-2023 (approximately 4 months of this study)

Population: Analysis population included all eligible participants whose data were retrieved and observed in this study. All participants reported under Number of Participants Analyzed contributed data to the table; however, may not have evaluable data for every row. Here, Number of Participants Analyzed signifies participants evaluable for this outcome measure and Number Analyzed signifies number of participants evaluable for specified rows.
