Acquired angioedema due to C1 inhibitor deficiency (C1INH-AAE) is a rare and potentially fatal syndrome of bradykinin-mediated angioedema characterized by episodes of angioedema without urticaria. It typically manifests with nonpitting edema of the skin and edema in the gastrointestinal (GI) tract mucosa or upper airway. Edema of the upper airway and tongue may lead to life-threatening asphyxiation. C1INH-AAE is typically under-diagnosed because of its rarity and its propensity to mimic more common abdominal conditions and allergic reactions...

Mesenchymal stromal cells support acute myeloid leukemia cell survival in the bone marrow microenvironment. Protein expression profiles of acute myeloid leukemia-derived mesenchymal stromal cells are unknown. Reverse phase protein array analysis was performed to compare expression of 151 proteins from acute myeloid leukemia mesenchymal stromal cells (n = 106) with mesenchymal stromal cells from healthy donors (n = 71). Protein expression differed significantly between the two groups with nineteen proteins overexpressed in leukemia stromal cells and nine overexpressed in normal stromal cells...

Recently clinical trials utilizing genetically engineered T cells expressing a chimeric antigen receptor (CAR) that is half monoclonal antibody and half T-cell receptor have demonstrated remarkable response in patients with advanced cancers like relapsed or refractory acute lymphoblastic leukemia (ALL) and lymphoma. Moreover, emerging chimeric genome editing tools such as zinc-finger nucleases (ZNFs), transcription activator-like effector nucleases (TALENs) and clustered regulatory interspaced short palindromic repeat (CRISPR)/Cas composed of sequence-specific DNA binding module(s) linked to a non-specific DNA cleavage domain have made possible to dramatically expand the ability to manipulate cells aim to treat and/or study a wide range of diseases including cancer...

The prognosis of adults with relapsed/refractory (R/R) acute lymphoblastic leukemia (ALL) remains dismal even at this day and age. With salvage chemotherapy, only 29% (range 18 to 44%) of the patients with R/R ALL can be induced into complete remission (CR), with a median overall survival (OS) of 4 months (range 2-6 months). Blinatumomab and inotuzumab ozogamycin (IO) are immunotherapeutic agents that increased CR to 80% and extended survival to 7.7 months in this high-risk population of patients. In the last few years, chimeric antigen receptor (CAR)--engineered T cells have led to major progress in cancer immunotherapy...

Approximately 30-40% of patients with acute myeloid leukemia (AML) experience induction failures. In these patients who do not achieve remission with two cycles of standard induction therapies, the probability of achieving remission with subsequent inductions is very limited. Hematopoietic stem cell transplantation (HSCT) is the only curative option for these patients, but high relapse rate and transplant-related mortality often preclude them to proceed to transplant. Thus, AML not in remission at time of HSCT remains a huge unmet need in current HSCT practice, particularly if the patient does not have an HLA-matched donor identified by the time of two induction failures...

In the Asia-Pacific region, treatment options are limited for patients with relapsed/refractory chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL). Rituximab is widely used in this setting when purine analog-based therapies are not appropriate. We evaluated the efficacy and safety of ibrutinib compared with rituximab in a randomized, open-label phase 3 study in predominantly Asian patients with relapsed/refractory CLL/SLL. Patients (N = 160) were randomly assigned 2:1 to receive 420 mg ibrutinib (n = 106) until disease progression (PD) or unacceptable toxicity or up to six cycles of rituximab (n = 54)...

Acute lymphoblastic leukemia (ALL) is the most common pediatric malignancy. Although the therapy of ALL has significantly improved, the heterogeneous genetic landscape of the disease often causes relapse, which is difficult to treat. Achieving a positive outcome for patients with relapsed or refractory ALL remains a challenging issue. The high prevalence of NOTCH-activating mutations in T-cell acute lymphoblastic leukemia (T-ALL) and the central role of NOTCH signaling in regulating cell survival and growth of ALL provide a rationale for the development of Notch signaling-targeted strategies in this disease...

Immunotherapy is now the fourth pillar of cancer therapy, with surgery, radiation, and traditional chemotherapy being the remaining pillars. Over the past decade, enthusiasm for immunotherapy has increased because of, in part, data showing that it consistently improves overall survival in select patients with historically refractory cancers. This issue covers various aspects of immunotherapy ranging from use of 1) chimeric antigen receptor (CAR) T cells to treat patients with B-cell acute lymphoblastic leukemia; 2) population pharmacokinetic/dynamic modeling to develop new immune checkpoint inhibitors; and 3) simulations of existing population pharmacokinetic models of immunotherapy to minimize waste without compromising exposure and efficacy...

Multi-kinase inhibitor sorafenib showed dramatic effects in acute myeloid leukemia (AML) cells harboring fms-related tyrosine kinase 3-internal tandem duplication(FLT3-ITD) mutation. However, little is known about its therapeutic effects and underlying mechanisms on AML without this mutation. In this report, sorafenib monotherapy was utilized as a salvage treatment in two relapse/refractory AML patients without FLT3-ITD mutation. A central nervous system(CNS) relapsed patient exhibited significant shrink of tumor volume, the other patient with refractory AML, arising from chronic myelomonocytic leukemia, achieved hematological improvements...

Inotuzumab ozogamicin is an antibody-drug conjugate comprised of a humanized anti-CD22 monoclonal antibody conjugated to calicheamicin, a cytotoxic antibiotic agent. Inotuzumab ozogamicin binds to CD22-expressing tumor cells, resulting in apoptotic cell death. Based on the results of the pivotal, phase III INO-VATE trial in acute lymphoblastic leukemia (ALL), approval of inotuzumab ozogamicin was recently granted for the treatment of patients with relapsed or refractory ALL, a group that otherwise has a poor prognosis with standard chemotherapy...

BACKGROUND: Inotuzumab ozogamicin (InO), an anti-CD22 antibody-calicheamicin conjugate, demonstrated superior clinical activity versus standard-of-care (SOC) chemotherapies for relapsed/refractory B-cell acute lymphoblastic leukemia in the phase 3 randomized controlled INO-VATE trial. The authors assessed patient-reported outcomes (PROs) from that study. METHODS: Patients were randomized to receive either InO (1.8 mg/m2 per cycle for ≤6 cycles) or SOC (fludarabine/cytarabine [ara-C]/granulocyte colony-stimulating factor, or ara-C plus mitoxantrone, or high-dose ara-C for ≤4 cycles) and completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire and the EuroQoL 5 Dimensions Questionnaires at baseline, on day 1 of each cycle, and at the end of treatment...

We evaluated the efficacy and toxicity of T-cell-replete haploidentical stem cell transplantation (TCR-haploSCT) using low-dose antithymocyte globulin (ATG) in children with refractory/relapsed (R/R) acute leukemia. From October 2009 to April 2016, 39 consecutive patients with R/R acute leukemia who underwent TCR-haploSCT were included. At the time of TCR-haploSCT, 17 patients were in complete remission (CR), but 22 had active disease. Thirty-three patients received a myeloablative regimen and six received a reduced-intensity conditioning regimen...

Patients with PDGFRA-rearranged hematopoietic neoplasms typically present with chronic eosinophilic leukemia and rarely with acute myeloid leukemia or T-lymphoblastic lymphoma. However, mature T-cell lymphoma has not been previously associated with PDGFRA aberrations. We report a patient who presented with simultaneous T-lymphoblastic lymphoma, focal myeloid proliferation, and cutaneous cytotoxic T-cell lymphoma refractory to chemotherapy. The presence of myeloid and lymphoid lineages prompted genetic and molecular studies...

Two autologous chimeric antigen receptor (CAR) T cell therapies (Kymriah™ and Yescarta™) were recently approved by the FDA. Kymriah™ for the treatment of pediatric patients and young adults with refractory or relapse (R/R) B cell precursor acute lymphoblastic leukemia and Yescarta™ for the treatment of adult patients with R/R large B cell lymphoma. In common, both drugs are CD19-specific CAR T cell therapies lysing CD19-positive targets. Their dramatic efficacy in the short term has been highlighted by many media reports...

In recent years, high-throughput sequencing techniques have been developed for cancerology and many clinical trials are currently structured around biomarkers that can guide specific treatment choices. This approach is characteristic of precision medicine, which is actually a concept initiated several decades ago with, for example, retinoic acid in promyelocytic leukemia. This paper will review the different types of molecular alterations and « -omics » biological analyses, bioinformatics tools, coupled drug/biomarkers already validated, the ethical issues of whole genomic sequencing of an individual as part of an inclusion in a clinical trial and finally the first results of precision medicine trials...

BACKGROUND: Anti-CD19 CAR T cell therapy has demonstrated high response rates in patients with relapsed or refractory (r/r) B cell malignancies but is associated with significant toxicity. Cytokine release syndrome (CRS) is the most significant complication associated with CAR T cell therapy, and it is critical to have a reproducible and easy method to grade CRS after CAR T cell infusions. DISCUSSION: The Common Terminology Criteria for Adverse Events scale is inadequate for grading CRS associated with cellular therapy...

Acute myeloid leukemia (AML) is a heterogeneous disease with cure rates of only 30-40% in patients <60 years old. Cytogenetic and molecular markers have improved our understanding of the different prognostic entities in AML. FLT3 mutations are present in 30-40% of AML cases, conferring a poor prognosis with reduced survival. AXL activates FLT3, impacting adversely on outcome. Both FLT3 and AXL constitute promising molecular targets. ASP2215 (gilteritinib) is a novel, dual FLT3/AXL inhibitor with promising early phase trial data (NCT02014558)...

Anti-CD22 moxetumomab pasudotox achieved 46% complete remissions (CRs) in previously reported phase I testing in relapsed/refractory hairy cell leukemia (HCL; n=28). The importance of minimal residual disease (MRD) after CR in HCL is unknown. A 21-patient extension cohort received 50 µg/kg every other day for 3 doses in 4-week cycles. These patients plus 12 previously reported at this upper dose level received 143 cycles without dose-limiting toxicity. The combined 33-patient cohort achieved 64% CR and 88% overall response rates, with median CR duration of 42...
