• Relapsed or refractory disease, defined as first or greater bone marrow relapse from CR or overall response, specifically: * Any bone marrow relapse after allogeneic HSCT: subjects must be at least 1 month from HSCT at the time of screening and off immunosuppressive medication for at least 2 weeks at time of initial treatment (with the exception of low-dose steroids =< 20 mg prednisone equivalent) and have no active graft versus (vs.) host disease (GVHD); * Philadelphia chromosome (Ph) negative B-ALL which has not achieved CR or CRi after at least 1 attempt at remission induction using standard intensive chemotherapy regimen(s); * Philadelphia chromosome (Ph) positive B-cell ALL intolerant to or ineligible for BCR-ABL tyrosine kinase inhibitor (TKI) therapy or with disease which has progressed after at least two lines of prior TKI therapy
• Participants of childbearing potential must agree to use adequate contraceptive methods (e.g., hormonal or barrier method of birth control; abstinence) prior to study entry. and for females, at least 8 months after the final dose of inotuzumab ozogamicin. Males with female partners of childbearing potential must agree to use adequate contraceptive prior to study entry and for at least 5 months after the final dose of inotuzumab ozogamicin. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately
• Participant must understand the investigational nature of this study and sign an Independent Ethics Committee/Institutional Review Board approved written informed consent form prior to receiving any study related procedure

Exclusion Criteria

• Receipt of chemotherapy, radiotherapy, or investigational drug therapy within 2 weeks prior to treatment on study or those who have not recovered from adverse events due to agents administered > 2 weeks earlier
• Participants on oral or injectable calcineurin inhibitors (e.g., cyclosporin, tacrolimus) within 4 weeks prior to study enrollment
• Active central nervous system involvement; patients who have a history of central nervous system (CNS) disease which has been effectively treated (as defined by at least one negative cerebrospinal sample prior to screening) are eligible
• Prior malignancy, unless treated with curative intent and with no evidence of active disease present for > 5 years before screening, with the following exceptions: * Subjects with stage I breast cancer that has been completely and successfully treated, requiring no therapy or only anti-hormonal therapy * Subjects with T1N0M0 or T2N0M0 colorectal cancer who have been completely and successfully resected and who are disease-free for > 2 years prior to screening * Subjects with indolent prostate cancer, defined as clinical stage T1 or T2a, Gleason score =< 6, and prostate-specific antigen (PSA) < 10 ng/mL, requiring no therapy or only anti-hormonal therapy * Subjects with a history of basal cell or squamous cell carcinoma of the skin, or carcinoma in situ of the cervix, fully resected, and with no evidence of active disease
• Uncontrolled intercurrent medical illness including, but not limited to, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that in the opinion of the investigator would limit compliance with study requirements
• Uncontrolled systemic fungal, bacterial, viral, or other infection defined as exhibiting ongoing signs and symptoms due to infection despite appropriate anti-infective therapy at time of screening
• Pregnant or nursing female participants
• Known active hepatitis B, known active hepatitis C, or any human immunodeficiency virus (HIV) infection at the time of screening
• Presence of grade II-IV acute or extensive chronic graft versus host disease (GVHD) at time of screening
• Unwilling or unable to follow protocol requirements
• Any condition which in the investigator’s opinion deems the participant an unsuitable candidate to receive study drug including, but not limited to, medical, psychological, familial, social, or geographical considerations
• The following special populations will be excluded from this study: * Cognitively impaired adults/adults with impaired decision-making capacity * Individuals who are not yet adults (infants, children, teenagers) * Pregnant women * Prisoners
