Introduction: Immediate postabortion intrauterine device (IUD) insertion is a safe, effective strategy to prevent subsequent unplanned pregnancy. Oregon is one of 5 US states where advanced practice clinicians perform aspiration abortions. This study compares outcomes of first-trimester aspiration abortion with immediate IUD insertion between advanced practice clinicians and physicians. Methods: We conducted a historical cohort study of first-trimester aspiration abortions with immediate IUD insertion performed at our center from 2009 to 2011. We extracted demographic and clinical data from patient charts. Immediate complications including excessive blood loss, perforation, and reaspirations were recorded at the time of procedure. We used descriptive statistics and multivariable logistic regression to test for differences in outcomes by clinician type. Results: Data were available on 669 of the 1134 combined procedures. Advanced practice clinicians performed 224 of these. There were no significant differences in immediate outcomes. The only immediate complications were reaspirations; 1.8% (4/224) in the advanced practice clinician group, and 2.0% (9/445) in the physician group (P = .83). Discussion: We found no differences in outcomes between provider type for immediate IUD insertion after first-trimester aspiration abortion. This study helps reinforce that advanced practice clinicians can provide immediate postaspiration abortion IUD insertions with similar outcomes to those of physicians. Many countries do not allow advanced practice clinicians to perform this service, but a change in policy could help address family planning provider shortages. © 2016 by the American College of Nurse-Midwives.

Obinutuzumabis aglycoengineered, type 2 anti-CD20humanizedantibodywith single-agent activity in relapsed chronic lymphocytic leukemia (CLL). With other CD20 antibodies, a dose-response relationship has been shown. We therefore performed a randomized phase 2 study in symptomatic, untreated CLL patients to evaluate if an obinutuzumab dose response exists. Obinutuzumab was given at a dose of 1000 mg (100 mg IV day 1, 900mgday 2, 1000mgday 8 and day 15 of cycle 1; 1000mgday 1 of cycles 2-8) or 2000mg (100mg IV day 1, 900 mg day 2, 1000mg day 3, 2000mg day 8 and day 15 of cycle 1; 2000mg day 1 of cycles 2-8). The primary end point was overall response rate (ORR). Eighty patients were enrolled with similardemographics: median age 67 years,41%high-risk Rai disease, and10%del(17p)(13.1).ORR(67% vs 49%,P5.08) and complete response (CR) or CR with incomplete cytopenia response (20% vs 5%) favored 2000 mg obinutuzumab. Overall, therapy was well tolerated, and infusion events were manageable. This study demonstrates significant efficacy of obinutuzumab monotherapy, for 1000mg as well as for 2000 mg, in untreated CLL patients with acceptable toxicity. Although exploratory, a dose-response relationshipmay exist, but its relevance to improving progression-free survival is uncertain and will require further follow-up. © 2016 by The American Society of Hematology.

BACKGROUND: The treatment of relapsed chronic lymphocytic leukemia (CLL) has resulted in few durable remissions. Bruton's tyrosine kinase (BTK), an essential component of B-cell-receptor signaling, mediates interactions with the tumor microenvironment and promotes the survival and proliferation of CLL cells. METHODS: We conducted a phase 1b-2 multicenter study to assess the safety, efficacy, pharmacokinetics, and pharmacodynamics of ibrutinib (PCI-32765), a first-in-class, oral covalent inhibitor of BTK designed for treatment of B-cell cancers, in patients with relapsed or refractory CLL or small lymphocytic lymphoma. A total of 85 patients, the majority of whom were considered to have high-risk disease, received ibrutinib orally once daily; 51 received 420 mg, and 34 received 840 mg. RESULTS: Toxic effects were predominantly grade 1 or 2 and included transient diarrhea, fatigue, and upper respiratory tract infection; thus, patients could receive extended treatment with minimal hematologic toxic effects. The overall response rate was the same in the group that received 420 mg and the group that received 840 mg (71%), and an additional 20% and 15% of patients in the respective groups had a partial response with lymphocytosis. The response was independent of clinical and genomic risk factors present before treatment, including advanced-stage disease, the number of previous therapies, and the 17p13.1 deletion. At 26 months, the estimated progression-free survival rate was 75% and the rate of overall survival was 83%. CONCLUSIONS: Ibrutinib was associated with a high frequency of durable remissions in patients with relapsed or refractory CLL and small lymphocytic lymphoma, including patients with high-risk genetic lesions.

Background: Available preclinical and phase 2 clinical data suggest that the addition of cetuximab, a monoclonal antibody directed against the epidermal growth factor receptor (EGFR), to chemotherapy might improve outcome in patients with advanced non-small-cell lung cancer (NSCLC). We aimed to assess whether the addition of cetuximab to chemotherapy improved progression-free survival in patients with recurrent or progressive NSCLC after platinum-based therapy. Methods: In this unmasked, open-label randomised phase 3 trial we enrolled patients with metastatic, unresectable, or locally advanced NSCLC from 121 sites in Canada and the USA. Eligible patients were those aged 18 years or older who had experienced progressive disease during or after one previous platinum-based regimen. Initially, patients were randomly assigned to receive either pemetrexed (500 mg/m2) or docetaxel (75 mg/m2) and then randomly assigned within each group to receive their chemotherapy with or without cetuximab (400 mg/m2 at first dose and 250 mg/m2 weekly thereafter) until disease progression or unacceptable toxicity. However, after a change in the standard of care, investigators chose whether to treat with pemetrexed or docetaxel on a patient-by-patient basis. The primary analysis was changed to compare progression-free survival with cetuximab plus pemetrexed versus pemetrexed, on an intention-to-treat basis. This study is registered with ClinicalTrials.gov, number NCT00095199. Findings: Between Jan 10, 2005, and Feb 10, 2010, we enrolled 939 patients; data for one patient was accidentally discarded. Of the remaining 938 patients, 605 received pemetrexed (301 patients with cetuximab and 304 alone) and 333 received docetaxel (167 in combination with cetuximab and 166 alone). Median progression-free survival with cetuximab plus pemetrexed was 2·9 months (95% CI 2·7-3·2) versus 2·8 months (2·5-3·3) with pemetrexed (HR 1·03, 95% CI 0·87-1·21; p=0·76). The most common grade 3-4 adverse events with cetuximab plus pemetrexed were fatigue (33 [11%] of 292 patients), acneiform rash (31 [11%]), dyspnoea (29 [10%]), and decreased neutrophil count (28 [10%]), and with pemetrexed alone were dyspnoea (35 [12%] of 289 patients), decreased neutrophil count (26 [9%]), and fatigue (23 [8%]). A significantly higher proportion of patients in the cetuximab plus pemetrexed group (119 [41%] of 292 patients) experienced at least one serious adverse event than those patients in the pemetrexed group (85 [29%] of 289 patients; p=0·0054). Nine (3%) of 292 treated patients in the cetuximab and pemetrexed group died of adverse events compared with five (2%) of 289 treated patients in the pemetrexed alone group. Interpretation: The use of cetuximab is not recommended in combination with chemotherapy in patients previously treated with platinum-based therapy.

Outcomes in older patients with Hodgkin lymphoma (HL) tend to be poor following conventional chemotherapy regimens. Treatment-related toxicity is significant and comorbidities often limit therapeutic options. This phase 2, open-label study evaluated the efficacy and safety of brentuximab vedotin, a CD30-directed antibody-drug conjugate, as frontline therapy in 27 HL patients aged ≥60 years. The objective response rate (ORR) was 92%, with 73% achieving complete remission. All patients achieved stable disease or better, and had decreased tumor volume following treatment. At the time of this analysis, themedian duration of objective response for efficacy-evaluable patients (N5 26) was 9.1 months (range, 2.8 to 20.91 months), median progression-free survival was 10.5 months (range, 2.61 to 22.31 months), and median overall survival had not been reached (range, 4.61 to 24.91 months). The observed adverse events (AEs) were generally consistent withthe known safety profile of brentuximab vedotin. Themost common AEs were peripheral sensory neuropathy (78%), fatigue (44%), and nausea (44%), and were ≤ grade 2 formost patients. The incidence of grade 3 peripheral neuropathy events was relatively high (30% overall), particularly among patients with the knownrisk factors of diabetes and/or hypothyroidism (46% vs 14% for those without). However, these risk factors were not associated with delayed time to resolution/improvement of peripheral neuropathy. Preliminary data showed no substantial age-related changes in brentuximab vedotin pharmacokinetics. Brentuximab vedotin monotherapy may provide a frontline treatment option for older patients who cannot tolerate conventional combination chemotherapy. © 2015 by The American Society of Hematology.
