The FDA's decision to approve inotuzumab ozogamicin for patients with relapsed or refractory acute lymphoblastic leukemia could open up further uses for the drug. It is being tested as a first-line treatment in combination with chemotherapy. The decision could also stimulate research into other antibody-drug conjugates.

The past decade witnessed the rapid development of adult B-lineage acute lymphoblastic leukemia (ALL) treatment. Beyond the development of chemotherapy regimens, immunotherapy is starting a new era with unprecedented complete remission (CR) rate. Targeting B-lineage-specific surface markers such as CD19, CD20, CD22, or CD52, immunotherapy has been demonstrating promising clinical results. Among the immunotherapeutic methods, naked monoclonal antibodies (mAbs), antibody-drug conjugate (ADC), bispecific T cell engager (BiTE), and chimeric antigen receptor (CAR) T cells are the main types...

Intravenous inotuzumab ozogamicin (Besponsa(®); Pfizer) is an anti-CD22 monoclonal antibody-calicheamicin conjugate that binds to CD22-expressing tumour cells. Upon binding, the complex is internalised and the cytotoxic calicheamicin derivative is released inside the cell, inducing double-strand DNA breakage and subsequent cell death. In June 2017, the EMA granted inotuzumab ozogamicin approval as monotherapy for the treatment of adults with relapsed or refractory CD22-positive B-cell precursor acute lymphoblastic leukaemia (ALL)...

Treatment of adult acute lymphoblastic leukemia (ALL) has largely relied on cytotoxic chemotherapy agents borrowed from successful treatment regimens of pediatric ALL. However, the high cure rates seen in pediatric ALL have not been replicated in adults. In recent years, the development of monoclonal antibodies targeting cell surface antigens, such as CD19 and CD20, have significantly improved outcomes when used alone or in combination with cytotoxic chemotherapy. With these novel agents come challenges in managing adverse events, understanding mechanisms of resistance and determining their optimal place in therapy alongside conventional chemotherapy and allogeneic stem cell transplant...

BACKGROUND: The INO-VATE study demonstrated efficacy and safety of inotuzumab ozogamicin versus standard care in adults with relapsed or refractory B-cell acute lymphoblastic leukaemia. Here, we report the frequency of, and potential risk factors for, hepatotoxicity in patients in this trial and after treatment and subsequent haemopoietic stem-cell transplantation (HSCT). METHODS: In this open-label, phase 3, multicentre, international study, adults with relapsed or refractory, CD22-positive, Philadelphia chromosome (Ph)-positive or Ph-negative B-cell acute lymphoblastic leukaemia who were due to receive first or second salvage treatment were randomly assigned (1:1) via an interactive voice response system to receive inotuzumab ozogamicin (starting dose 1·8 mg/m(2) per cycle [0·8 mg/m(2) on day 1; 0·5 mg/m(2) on days 8 and 15 of a 21-28 day cycle for ≤6 cycles]) or standard care (either fludarabine plus cytarabine plus granulocyte colony-stimulating factor, mitoxantrone plus cytarabine, or high-dose cytarabine)...

Acute lymphoblastic leukemia (ALL) is an uncommon disease with poor outcomes in older patients. Although intensive chemotherapy can induce complete responses in older patients, the mortality rate is unacceptably high. The 5-year survival rate for patients achieving a remission ranges from 17% to 23%. ALL is usually more aggressive in older patients, and these patients' reduced functional capacity renders them less able to tolerate treatment. The need for less-intensive, more-efficient treatment modalities in this population of frail and high-risk patients is evident...

The therapy of lymphomas has undergone a major expansion during the last decade. Novel therapeutic targets have appeared beyond classical chemotherapeutic combinations. These novel drugs have very pronounced action across lymphoma types, and their toxicity profile is usually better tolerable compared to standard chemotherapies. These new therapies are enabling us to offer treatment to those patients who have refractory disease, and we had no option to treat them before these drugs. The author describes several new therapeutic options...

PURPOSE OF REVIEW: To review recent studies that address important questions regarding the treatment of Philadelphia chromosome-positive ALL. RECENT FINDINGS: Less intensive non-myelosuppressive induction approaches can produce comparable anti-leukemic responses with less toxicity. Second-generation tyrosine kinase inhibitors (TKIs) are not clearly associated with superior outcomes compared to imatinib. Ponatinib is associated with lower early relapse rates, but has additional vascular risks...

In recent years, the identification of minimal residual disease (MRD) that persists after chemotherapy has emerged as the most powerful tool in determining the prognosis of patients with ALL, often superseding historically relevant prognostic factors. Multiple methods to detect MRD exist, each with their own advantages and disadvantages. Multiparameter flow cytometry and quantitative polymerase chain reaction are the most commonly used methods of MRD detection in clinical practice, although there is promise in the use of more sensitive assays utilizing next-generation sequencing that may be able to further refine MRD-based risk stratification...

Despite an improved understanding of disease biology and the use of multi-agent chemotherapy, the long-term survival of adults with B-cell acute lymphoblastic leukemia (B-ALL) ranges from 35% to 50%. Management of patients with relapsed B-ALL, a group characterized by dismal outcomes, poses a clinical challenge. To address this unmet need, novel therapeutics are being investigated in the setting of relapsed B-ALL with encouraging results. CD22 is an important B-cell antigen expressed in 80-90% of B-ALL cases...

About one-half of all Burkitt lymphoma (BL) patients are younger than 40 years, and one-third belong to the adolescent and young adult (AYA) subset, defined by an age between 15 and 25-40 years, based on selection criteria used in different reports. BL is an aggressive B-cell neoplasm displaying highly characteristic clinico-diagnostic features, the biologic hallmark of which is a translocation involving immunoglobulin and c-MYC genes. It presents as sporadic, endemic, or epidemic disease. Endemicity is pathogenetically linked to an imbalance of the immune system which occurs in African children infected by malaria parasites and Epstein-Barr virus, while the epidemic form strictly follows the pattern of infection by HIV...

PURPOSE: Adverse reactions reported in patients treated with antibody-calicheamicin conjugates such as gemtuzumab ozogamicin (Mylotarg) and inotuzumab ozogamicin include thrombocytopenia and sinusoidal obstruction syndrome (SOS). The objective of this experimental work was to investigate the mechanism for thrombocytopenia, characterize the liver injury, and identify potential safety biomarkers. EXPERIMENTAL DESIGN: Cynomolgus monkeys were dosed intravenously at 6 mg/m(2)/dose once every 3 weeks with a nonbinding antibody-calicheamicin conjugate (PF-0259) containing the same linker-payload as gemtuzumab ozogamicin and inotuzumab ozogamicin...

Monoclonal antibodies represent a major advance in treatment of acute lymphoblastic leukemia (ALL). Targeted delivery of these agents based on leukemic cell-surface receptor recognition, improves efficacy and minimizes off-target toxicity. The antigens CD19, CD20, CD22 and CD52, are the most common antigens to which monoclonal antibodies in B-cell ALL have been directed. Rituximab, an anti-CD20 antibody, in combination with conventional chemotherapy has been shown to improve survival in newly diagnosed CD20 positive B-cell ALL...

PURPOSE: The aim of this investigation was to develop a quantitative method to optimize inotuzumab ozogamicin (InO) dosage regimen in patients with indolent non-Hodgkin lymphoma (NHL) by simultaneously balancing safety and efficacy. METHODS: Pharmacokinetics (PK), safety and efficacy data were obtained from a phase 2 trial of InO administered intravenously to patients (n = 81) with indolent NHL. The PK was described by a two-compartment model which was linked to: (1) an exponential tumor growth model to describe tumor size time course (efficacy determinant expressed as objective response rate) and (2) a precursor-dependent platelet inhibition model to describe platelet time course (safety determinant expressed as thrombocytopenia grade)...
