Summary Background Patients with indolent non-Hodgkin lymphoma who fail to achieve adequate disease control with rituximab-based treatment have few treatment options and a poor prognosis. We aimed to ...assess a combination of obinutuzumab (GA101), a novel glyco-engineered type II anti-CD20 monoclonal antibody, and bendamustine in this patient population. Methods In this open-label, randomised, phase 3 study (GADOLIN), patients aged 18 years or older with histologically documented, CD20-positive indolent non-Hodgkin lymphoma refractory to rituximab were enrolled at 83 hospital and community sites in 14 countries in Europe, Asia, and North and Central America. Patients were randomly assigned (1:1) using a hierarchical dynamic randomisation scheme stratified by indolent non-Hodgkin lymphoma subtype, rituximab-refractory type, number of previous therapies, and geographical region, to receive induction treatment (six 28-day cycles) with obinutuzumab plus bendamustine or bendamustine monotherapy, both given intravenously. Obinutuzumab plus bendamustine dosing was obinutuzumab 1000 mg (days 1, 8, and 15, cycle 1; day 1, cycles 2–6) plus bendamustine 90 mg/m2 per day (days 1 and 2, cycles 1–6), and bendamustine monotherapy dosing was 120 mg/m2 per day (days 1 and 2, all cycles). Non-progressing patients in the obinutuzumab plus bendamustine group received obinutuzumab maintenance (1000 mg every 2 months) for up to 2 years. The primary endpoint was progression-free survival in all randomised patients, as assessed by an independent review committee. Safety was assessed in all patients who received any amount of obinutuzumab or bendamustine. This study is registered with ClinicalTrials.gov , number NCT01059630 , and has stopped recruiting patients. Findings Between April 15, 2010, and Sept 1, 2014, when the study was stopped after a pre-planned interim analysis, 396 patients were randomly assigned (194 to obinutuzumab plus bendamustine and 202 to bendamustine monotherapy). After a median follow-up time of 21·9 months (IQR 12·1–31·0) in the obinutuzumab plus bendamustine group and 20·3 months (9·5–29·7) in the bendamustine monotherapy group, progression-free survival was significantly longer with obinutuzumab plus bendamustine (median not reached 95% CI 22·5 months–not estimable) than with bendamustine monotherapy (14·9 months 12·8–16·6; hazard ratio 0·55 95% CI 0·40–0·74; p=0·0001). Grade 3–5 adverse events occurred in 132 (68%) of 194 patients in the obinutuzumab plus bendamustine group and in 123 (62%) of 198 patients in the bendamustine monotherapy group. The most frequent grade 3 or worse adverse events were neutropenia (64 33% in the obinutuzumab plus bendamustine group vs 52 26% in the bendamustine monotherapy group), thrombocytopenia (21 11% vs 32 16%), anaemia (15 8% vs 20 10%) and infusion-related reactions (21 11% vs 11 6%). Serious adverse events occurred in 74 patients (38%) in the obinutuzumab plus bendamustine group and in 65 patients (33%) in the bendamustine monotherapy group, and deaths due to adverse events occurred in 12 patients (6%) and 12 patients (6%), respectively. Three (25%) of 12 adverse event-related deaths in the obinutuzumab plus bendamustine group and five (42%) of 12 in the bendamustine monotherapy group were treatment related. Interpretation Obinutuzumab plus bendamustine followed by obinutuzumab maintenance has improved efficacy over bendamustine monotherapy in rituximab-refractory patients with indolent non-Hodgkin lymphoma, with manageable toxicity, and is a new treatment option for patients who have relapsed after or are no longer responding to rituximab-based therapy.

Summary Background Patients with relapsed or refractory B-cell non-Hodgkin lymphoma (NHL) have an unfavourable prognosis with few treatment options. Polatuzumab vedotin is an antibody–drug conjugate ...containing an anti-CD79B monoclonal antibody conjugated to the microtubule-disrupting agent monomethyl auristatin E. We aimed to assess the safety and clinical activity of polatuzumab vedotin in relapsed or refractory B-cell NHL and chronic lymphocytic leukaemia (CLL). Methods In this phase 1, multicentre, open-label study, we enrolled patients with documented NHL or CLL expected to express CD79B (confirmation of CD79B expression was not required) and for whom no suitable therapy of curative intent or higher priority existed from 13 centres. The primary endpoints of the study were to assess safety and tolerability, determine the maximum tolerated dose, and identify the recommended phase 2 dose of polatuzumab vedotin as a single agent and in combination with rituximab. A 3 + 3 dose-escalation design was used in which we treated patients with polatuzumab vedotin (0·1–2·4 mg/kg every 21 days) in separate dose-escalation cohorts for NHL and CLL. After determination of the recommended phase 2 dose, we enrolled patients with relapsed or refractory diffuse large B-cell lymphoma and relapsed or refractory indolent NHL into indication-specific cohorts. We also enrolled patients with relapsed or refractory NHL into an additional cohort to assess the feasibility of the combination of polatuzumab vedotin and rituximab 375 mg/m2 . Patients who received any dose of polatuzumab vedotin were available for safety analyses. This study is registered with ClinicalTrials.gov , number NCT01290549. Findings Between March 21, 2011, and Nov 30, 2012, we enrolled 95 patients (34 to the NHL dose-escalation cohort, 18 to the CLL dose-escalation cohort, 34 with NHL to the expansion cohort at the recommended phase 2 dose, and nine with NHL to the rituximab combination cohort; no expansion cohort of CLL was started due to lack of activity in the dose-escalation cohort). The recommended phase 2 dose in NHL was 2·4 mg/kg as a single agent and in combination with rituximab; the maximum tolerated dose in CLL was 1·0 mg/kg as a result of dose-limiting toxic effects reported in two of five patients given 1·8 mg/kg. Grade 3–4 adverse events were reported in 26 (58%) of 45 patients with NHL treated at the single-agent recommended phase 2 dose, and the most common grade 3–4 adverse events were neutropenia (18 40% of 45), anaemia (five 11%), and peripheral sensory neuropathy (four 9%). Serious adverse events were reported in 17 (38%) of 45 patients, and included diarrhoea (two patients), lung infection (two patients), disease progression (two patients), and lung disorder (two patients). Seven (77%) of nine patients in the rituximab combination cohort had a grade 3–4 adverse event, with neutropenia (five 56%), anaemia (two 22%), and febrile neutropenia (two 22%) reported in more than one patient. 11 (12%) of 95 patients died during the study: eight with relapsed or refractory diffuse large B-cell lymphoma (due to progressive disease in four patients, infections in three patients two treatment related, and treatment-related worsening ascites in one patient) and three with relapsed or refractory CLL (due to progressive disease, pulmonary infection, and pneumonia; none thought to be treatment-related). At the recommended phase 2 dose, objective responses were noted in 23 of 42 activity-evaluable patients with NHL given single-agent polatuzumab vedotin (14 of 25 with diffuse large B-cell lymphoma, seven of 15 with indolent NHL, and two with mantle-cell lymphoma) and seven of nine patients treated with polatuzumab vedotin combined with rituximab. No objective responses were observed in patients with CLL. Interpretation Polatuzumab vedotin has an acceptable safety and tolerability profile in patients with NHL but not in those with CLL. Its clinical activity should be further assessed in NHL. Funding Genentech.

The doctrine of the Incarnation lies at the heart of Christianity. But the idea that 'God was in Christ' has become a much-debated topic in modern theology. Oliver Crisp addresses six key issues in ...the Incarnation defending a robust version of the doctrine, in keeping with classical Christology. He explores perichoresis, or interpenetration, with reference to both the Incarnation and Trinity. Over two chapters Crisp deals with the human nature of Christ and then provides an argument against the view, common amongst some contemporary theologians, that Christ had a fallen human nature. He considers the notion of divine kenosis or self-emptying, and discusses non-Incarnational Christology, focusing on the work of John Hick. This view denies Christ is God Incarnate, regarding him as primarily a moral exemplar to be imitated. Crisp rejects this alternative account of the nature of Christology.
