Multicenter StudyPhase II study of bendamustine combined with rituximab in relapsed/refractory mantle cell lymphoma: efficacy, tolerability, and safety findings.
In most cases of relapsed/refractory mantle cell lymphoma (MCL), patients respond to salvage therapy, though typically responses are partial and/or transient followed by disease progression, even with newer agents (e.g., ibrutinib). In this multicenter, open-label, single-arm, phase II study, patients with relapsed/refractory non-blastoid MCL received bendamustine 90 mg/m(2) (days 1 and 2) and rituximab 375 mg/m(2) (day 1) for 6 planned 28-day cycles. Functional imaging with 18-fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography (18F-FDG PET/CT) was conducted at baseline and after cycle 6. ⋯ Main non-hematologic adverse events were nausea (69 %), fatigue (56 %), decreased appetite (42 %), constipation (38 %), diarrhea (36 %), vomiting (36 %), and decreased weight (31 %). Grade 3/4 neutropenia and lymphopenia occurred in 44 and 89 % of patients, respectively. ORR and CR rate compared favorably with single-agent ibrutinib (ORR, 67 %; CR, 23 %); bendamustine-rituximab is an effective therapy with manageable toxicity in relapsed/refractory MCL.

Randomized Controlled TrialEfficacy and safety of the thrombopoietin receptor agonist romiplostim in patients aged ≥ 65 years with immune thrombocytopenia.
Thrombopoietin receptor agonists increase platelet counts and reduce bleeding risk in patients with immune thrombocytopenia (ITP). Studies have reported that these agents may represent a risk factor for thromboembolic events, especially in the elderly, who are at increased risk for such complications relative to younger patients. In this retrospective analysis, efficacy and safety data for romiplostim in patients with ITP aged ≥65 years versus those aged <65 years are described. ⋯ Duration-adjusted AE rates were similar for romiplostim versus placebo/SOC in older and younger patients. The risks for grade ≥ 3 bleeding (RR 1.92; 95% CI, 0.47-7.95) and thromboembolic events (RR 3.85; 95% CI, 0.53-27.96) were numerically but not significantly higher for romiplostim versus placebo/SOC in patients ≥ 65 years. Romiplostim is effective and, with the exception of nonsignificant trends showing increased risks of grade ≥ 3 bleeding and thromboembolic events (a trend observed in other studies), generally well tolerated in older patients with ITP.
