ReviewInotuzumab ozogamicin for the treatment of acute lymphoblastic leukemia.
Acute lymphoblastic leukemia (ALL) is an uncommon disorder that affects about 20% of adults with acute leukemia. Historically, those who relapse from this condition have a dismal prognosis. Recent developments in immunoconjugate usage has changed the landscape of lymphoid B-cell malignancy therapy. ⋯ The article further includes the published phase I, II and III studies in ALL and considers the safety and efficacy of this treatment. Expert opinion: Inotuzumab ozogamicin is likely to be used, primarily, as a potent agent for relapsed ALL, either as the first choice or for those who fail treatment with blinatumumab. Its potential in newly diagnosed patients is currently unknown, such that the overall impact is likely to be important, but limited.

ReviewImmunotherapy in managing metastatic melanoma: which treatment when?
Ten to fifteen percent of melanoma patients develop distant or unresectable metastasis requiring systemic treatment. Around 45% of the patients diagnosed with metastatic cutaneous melanoma harbor a BRAFV600 mutation and derive benefit from combined targeted therapy with MAPK pathway inhibitors. These offer a rapid response that translates into improvement of symptoms and increased quality of life. ⋯ However, there are still unanswered questions of the best therapy sequence, the clear superiority of combined immunotherapy versus monotherapy in all patients, and therapy duration. Since different promising treatments will become available, clinical trials comparing the diverse options in terms of safety, efficacy and cost- effectiveness are required to make the right decisions. Consequently, patients should be encouraged to participate in clinical trials, whenever possible.

Infliximab biosimilar CT-P13 therapy is effective and safe in maintaining remission in Crohn's disease and ulcerative colitis - experiences from a single center.
CT-P13, the first biosimilar monoclonal antibody to infliximab (IFX), has been confirmed to be efficacious in inducing remission in inflammatory bowel diseases (IBD). The aim of this study was to evaluate the long-term efficacy and safety of CT-P13 therapy in Crohn's disease (CD) and ulcerative colitis (UC), and to identify predictors of sustained clinical response during a 54-week CT-P13 treatment period. ⋯ This study confirmed the long-term efficacy and safety of CT-P13 therapy in IBD. Response rates at week 54 were similar in CD and UC.

Idarucizumab for the treatment of hemorrhage and dabigatran reversal in patients requiring urgent surgery or procedures.
Idarucizumab is a specific antagonist for dabigatran etexilate (DE). The recent market authorization of idarucizumab in Europe and the USA may reassure prescribers of DE, as it can increase the safety of the emergency management of patients taking this anticoagulant. However, idarucizumab use should be limited to specific indications to avoid unnecessary risks to patients and costs to healthcare systems. ⋯ Information regarding the clinical context in which patients on DE are admitted for emergency treatment, and accurate laboratory tests of dabigatran plasma level during reversal may inform selection and help with the follow-up of patients who may benefit from idarucizumab. Idarucizumab should be integrated into protocol for the emergency management of patients on DE. Furthermore, the benefit of idarucizumab in specific indications such as acute ischemic stroke should be investigated.

T-cell lymphoma is a relatively rare hematologic malignancy that accounts for 10-20% of non-Hodgkin lymphomas. Treatment strategies for T-cell lymphomas are different from that for B-cell lymphomas and have poor prognoses. Among various subtypes of T-cell lymphomas, adult T-cell leukemia-lymphoma (ATL) has the worst prognosis. ⋯ Expert opinion: Mogamulizumab has potent clinical efficacy against CCR4-positive T-cell lymphomas, especially against ATL. Among various toxicities associated with mogamulizumab, skin eruptions are the most significant. Although there are several effective competitors, mogamulizumab has a unique mechanism and is expected to be a key agent for treating CCR4-positive T-cell lymphomas, especially ATL.
