This randomised multicentre trial was conducted to establish the optimal duration of palliative chemotherapy in advanced non-small-cell lung cancer (NSCLC). We compared a policy of three vs six courses of new-generation platinum-based combination chemotherapy with regard to effects on quality of life (QoL) and survival. Patients with stage IIIB or IV NSCLC and WHO performance status (PS) 0–2 were randomised to receive three (C3) or six (C6) courses of carboplatin (area under the curve (AUC) 4, Chatelut's formula, equivalent to Calvert's AUC 5) on day 1 and vinorelbine 25 mg m −2 on days 1 and 8 of a 3-week cycle. Key end points were QoL at 18 weeks, measured with EORTC Quality of Life Questionnaire (QLQ)-C30 and QLQ-LC13, and overall survival. Secondary end points were progression-free survival and need of palliative radiotherapy. Two hundred and ninety-seven patients were randomised (C3 150, C6 147). Their median age was 65 years, 30% had PS 2 and 76% stage IV disease. Seventy-eight and 54% of C3 and C6 patients, respectively, completed all scheduled chemotherapy courses. Compliance with QoL questionnaires was 88%. There were no significant group differences in global QoL, pain or fatigue up to 26 weeks. The dyspnoea palliation rate was lower in the C3 arm at 18 and 26 weeks ( P <0.05), but this finding was inconsistent across different methods of analysis. Median survival in the C3 group was 28 vs 32 weeks in the C6 group ( P =0.75, HR 1.04, 95% CI 0.82–1.31). One- and 2-year survival rates were 25 and 9% vs 25 and 5% in the C3 and C6 arm, respectively. Median progression-free survival was 16 and 21 weeks in the C3 and C6 groups, respectively ( P =0.21, HR 0.86, 95% CI 0.68–1.08). In conclusion, palliative chemotherapy with carboplatin and vinorelbine beyond three courses conveys no survival or consistent QoL benefits in advanced NSCLC.

The replacement of bleomycin with the immune drug conjugate brentuximab vedotin in the first-line chemotherapy regimen for advanced Hodgkin’s lymphoma prolonged both progression-free and overall survival.

Incorporating brentuximab vedotin into the treatment of advanced-stage classic Hodgkin's lymphoma improves outcomes in adult and pediatric patients. However, brentuximab vedotin increases the toxic effects of treatment in adults, more than half of pediatric patients who receive the drug undergo consolidative radiation, and relapse remains a challenge. Programmed death 1 blockade is effective in Hodgkin's lymphoma, including in preliminary studies involving previously untreated patients. We conducted a phase 3, multicenter, open-label, randomized trial involving patients at least 12 years of age with stage III or IV newly diagnosed Hodgkin's lymphoma. Patients were randomly assigned to receive brentuximab vedotin with doxorubicin, vinblastine, and dacarbazine (BV+AVD) or nivolumab with doxorubicin, vinblastine, and dacarbazine (N+AVD). Prespecified patients could receive radiation therapy directed to residual metabolically active lesions. The primary end point was progression-free survival, defined as the time from randomization to the first observation of progressive disease or death from any cause. Of 994 patients who underwent randomization, 970 were included in the intention-to-treat population for efficacy analyses. At the second planned interim analysis, with a median follow-up of 12.1 months, the threshold for efficacy was crossed, indicating that N+AVD significantly improved progression-free survival as compared with BV+AVD (hazard ratio for disease progression or death, 0.48; 99% confidence interval [CI], 0.27 to 0.87; two-sided P = 0.001). Owing to the short follow-up time, we repeated the analysis with longer follow-up; with a median follow-up of 2.1 years (range, 0 to 4.2 years), the 2-year progression-free survival was 92% (95% CI, 89 to 94) with N+AVD, as compared with 83% (95% CI, 79 to 86) with BV+AVD (hazard ratio for disease progression or death, 0.45; 95% CI, 0.30 to 0.65). Overall, 7 patients received radiation therapy. Immune-related adverse events were infrequent with nivolumab; brentuximab vedotin was associated with more treatment discontinuation. N+AVD resulted in longer progression-free survival than BV+AVD in adolescents and adults with stage III or IV advanced-stage classic Hodgkin's lymphoma and had a better side-effect profile.

Cisplatin-based adjuvant chemotherapy is the standard of care for patients with resected stage II–IIIA non-small-cell lung cancer (NSCLC). RADIANT and SELECT trial data suggest patients with EGFR-mutant stage IB–IIIA resected NSCLC could benefit from adjuvant EGFR tyrosine kinase inhibitor treatment. We aimed to compare the efficacy of adjuvant gefitinib versus vinorelbine plus cisplatin in patients with completely resected EGFR-mutant stage II–IIIA (N1–N2) NSCLC. We did a randomised, open-label, phase 3 trial at 27 centres in China. We enrolled patients aged 18–75 years with completely resected (R0), stage II–IIIA (N1–N2), EGFR-mutant (exon 19 deletion or exon 21 Leu858Arg) NSCLC. Patients were stratified by N stage and EGFR mutation status and randomised (1:1) by Pocock and Simon minimisation with a random element to either gefitinib (250 mg once daily) for 24 months or intravenous vinorelbine (25 mg/m2 on days 1 and 8) plus intravenous cisplatin (75 mg/m2 on day 1) every 3 weeks for four cycles. The primary endpoint was disease-free survival in the intention-to-treat population, which comprised all randomised patients; the safety population included all randomised patients who received at least one dose of study medication. Enrolment to the study is closed but survival follow-up is ongoing. The study is registered with ClinicalTrials.gov, number NCT01405079. Between Sept 19, 2011, and April 24, 2014, 483 patients were screened and 222 patients were randomised, 111 to gefitinib and 111 to vinorelbine plus cisplatin. Median follow-up was 36·5 months (IQR 23·8–44·8). Median disease-free survival was significantly longer with gefitinib (28·7 months [95% CI 24·9–32·5]) than with vinorelbine plus cisplatin (18·0 months [13·6–22·3]; hazard ratio [HR] 0·60, 95% CI 0·42–0·87; p=0·0054). In the safety population, the most commonly reported grade 3 or worse adverse events in the gefitinib group (n=106) were raised alanine aminotransferase and asparate aminotransferase (two [2%] patients with each event vs none with vinorelbine plus cisplatin). In the vinorelbine plus cisplatin group (n=87), the most frequently reported grade 3 or worse adverse events were neutropenia (30 [34%] patients vs none with gefitinib), leucopenia (14 [16%] vs none), and vomiting (eight [9%] vs none). Serious adverse events were reported for seven (7%) patients who received gefitinib and 20 (23%) patients who received vinorelbine plus cisplatin. No interstitial lung disease was noted with gefitinib. No deaths were treatment related. Adjuvant gefitinib led to significantly longer disease-free survival compared with that for vinorelbine plus cisplatin in patients with completely resected stage II–IIIA (N1–N2) EGFR-mutant NSCLC. Based on the superior disease-free survival, reduced toxicity, and improved quality of life, adjuvant gefitinib could be a potential treatment option compared with adjuvant chemotherapy in these patients. However, the duration of benefit with gefitinib after 24 months might be limited and overall survival data are not yet mature.

In a large randomized trial that compares regimens in which brentuximab vedotin replaced bleomycin, the group receiving the brentuximab had a 4.9 percentage-point improvement in modified progression-free survival, less pulmonary toxicity, and more myelotoxicity and neurotoxicity.

Combined-modality treatment consisting of chemotherapy and consolidation radiotherapy is standard of care for patients with early-stage unfavourable Hodgkin lymphoma. However, the use of radiotherapy can have long-term sequelae, which is of particular concern, as Hodgkin lymphoma is frequently diagnosed in young adults with a median age of approximately 30 years. In the German Hodgkin Study Group HD17 trial, we investigated whether radiotherapy can be omitted without loss of efficacy in patients who have a complete metabolic response after receiving two cycles of escalated doses of etoposide, cyclophosphamide, and doxorubicin, and regular doses of bleomycin, vincristine, procarbazine, and prednisone (eBEACOPP) plus two cycles of doxorubicin, bleomycin, vinblastine, dacarbazine (ABVD) chemotherapy (2 + 2). In this multicentre, open-label, randomised, phase 3 trial, patients (aged 18–60 years) with newly diagnosed early-stage unfavourable Hodgkin lymphoma (all histologies) and an Eastern Cooperative Oncology Group performance status of 2 or less were enrolled at 224 hospitals and private practices in Germany, Switzerland, Austria, and the Netherlands. Patients were randomly assigned (1:1) to receive either standard combined-modality treatment, consisting of the 2 + 2 regimen (eBEACOPP consisted of 1250 mg/m2 intravenous cyclophosphamide on day 1, 35 mg/m2 intravenous doxorubicin on day 1, 200 mg/m2 intravenous etoposide on days 1–3, 100 mg/m2 oral procarbazine on days 1–7, 40 mg/m2 oral prednisone on days 1–14, 1·4 mg/m2 intravenous vincristine on day 8 [maximum dose of 2 mg per cycle], and 10 mg/m2 intravenous bleomycin on day 8; ABVD consisted of 25 mg/m2 intravenous doxorubicin, 10 mg/m2 intravenous bleomycin, 6 mg/m2 intravenous vinblastine, and 375 mg/m2 intravenous dacarbazine, all given on days 1 and 15) followed by 30 Gy involved-field radiotherapy (standard combined-modality treatment group) or PET4-guided treatment, consisting of the 2 + 2 regimen followed by 30 Gy of involved-node radiotherapy only in patients with positive PET at the end of four cycles of chemotherapy (PET4; PET4-guided treatment group). Randomisation was done centrally and used the minimisation method and seven stratification factors (centre, age, sex, clinical symptoms, disease localisation, albumin concentration, and bulky disease), and patients and investigators were masked to treatment allocation until central review of the PET4 examination had been completed. With the final analysis presented here, the primary objective was to show non-inferiority of the PET4-guided strategy in a per-protocol analysis of the primary endpoint of progression-free survival. We defined non-inferiority as an absolute difference of 8% in the 5-year progression-free survival estimates between the two groups. Safety analyses were done in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, NCT01356680. Between Jan 13, 2012, and March 21, 2017, we enrolled and randomly assigned 1100 patients to the standard combined-modality treatment group (n=548) or to the PET4-guided treatment group (n=552); two patients in each group were found ineligible after randomisation. At a median follow-up of 46·2 months (IQR 32·7–61·2), 5-year progression-free survival was 97·3% (95% CI 94·5–98·7) in the standard combined-modality treatment group and 95·1% (92·0–97·0) in the PET4-guided treatment group (hazard ratio 0·523 [95% CI 0·226–1·211]). The between-group difference was 2·2% (95% CI −0·9 to 5·3) and excluded the non-inferiority margin of 8%. The most common grade 3 or 4 acute haematological adverse events were leucopenia (436 [83%] of 528 patients in the standard combined-modality treatment group vs 443 [84%] of 529 patients in the PET4-guided treatment group) and thrombocytopenia (139 [26%] vs 176 [33%]), and the most frequent acute non-haematological toxic effects were infection (32 [6%] vs 40 [8%]) and nausea or vomiting (38 [7%] vs 29 [6%]). The most common acute radiotherapy-associated adverse events were dysphagia (26 [6%] in the standard combined-modality treatment group vs three [2%] in the PET4-guided treatment group) and mucositis (nine [2%] vs none). 229 serious adverse events were reported by 161 (29%) of 546 patients in the combined-modality treatment group, and 235 serious adverse events were reported by 164 (30%) of 550 patients in the PET4-guided treatment group. One suspected unexpected serious adverse reaction (infection) leading to death was reported in the PET4-guided treatment group. PET4-negativity after treatment with 2 + 2 chemotherapy in patients with newly diagnosed early-stage unfavourable Hodgkin lymphoma allows omission of consolidation radiotherapy without a clinically relevant loss of efficacy. PET4-guided therapy could thereby reduce the proportion of patients at risk of the late effects of radiotherapy. Deutsche Krebshilfe.

Investigators examined whether the intensity of treatment can be reduced in patients with early-stage Hodgkin's lymphoma without compromising antitumor efficacy. In a comparison of two with four cycles of ABVD chemotherapy plus either 20 or 30 Gy of involved-field radiation therapy, no significant differences were noted in disease-free or overall survival between the most and the least intensive regimens. Radiation therapy was the original mainstay of treatment for patients who had early-stage Hodgkin's lymphoma with a favorable prognosis. With the use of such techniques as extended-field radiation therapy and total lymphoid irradiation, more than 80% of patients with localized disease became long-term survivors. However, the relapse rate with radiation therapy alone ranged from 20 to 40%, 1 – 3 and extended-field radiation therapy and total lymphoid irradiation were associated with the occurrence of secondary solid tumors. 4 – 8 The integration of a chemotherapy regimen consisting of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) 9 with radiation therapy resulted in greater efficacy and allowed the . . .

Platinum-based doublet chemotherapy is recommended to treat advanced non-small-cell lung cancer (NSCLC) in fit, non-elderly adults, but monotherapy is recommended for patients older than 70 years. We compared a carboplatin and paclitaxel doublet chemotherapy regimen with monotherapy in elderly patients with advanced NSCLC. In this multicentre, open-label, phase 3, randomised trial we recruited patients aged 70–89 years with locally advanced or metastatic NSCLC and WHO performance status scores of 0–2. Patients received either four cycles (3 weeks on treatment, 1 week off treatment) of carboplatin (on day 1) plus paclitaxel (on days 1, 8, and 15) or five cycles (2 weeks on treatment, 1 week off treatment) of vinorelbine or gemcitabine monotherapy. Randomisation was done centrally with the minimisation method. The primary endpoint was overall survival, and analysis was done by intention to treat. This trial is registered, number NCT00298415. 451 patients were enrolled. 226 were randomly assigned monotherapy and 225 doublet chemotherapy. Median age was 77 years and median follow-up was 30·3 months (range 8·6–45·2). Median overall survival was 10·3 months for doublet chemotherapy and 6·2 months for monotherapy (hazard ratio 0·64, 95% CI 0·52–0·78; p<0·0001); 1-year survival was 44·5% (95% CI 37·9–50·9) and 25·4% (19·9–31·3), respectively. Toxic effects were more frequent in the doublet chemotherapy group than in the monotherapy group (most frequent, decreased neutrophil count (108 [48·4%] vs 28 [12·4%]; asthenia 23 [10·3%] vs 13 [5·8%]). Despite increased toxic effects, platinum-based doublet chemotherapy was associated with survival benefits compared with vinorelbine or gemcitabine monotherapy in elderly patients with NSCLC. We feel that the current treatment paradigm for these patients should be reconsidered. Intergroupe Francophone de Cancérologie Thoracique, Institut National du Cancer.

Roughly 70–80% of patients with advanced stage Hodgkin's lymphoma are cured with various first-line and second-line treatments, including ABVD, BEACOPP, and stem-cell transplantation. Brentuximab vedotin has shown significant clinical activity, with a manageable safety profile, in patients with relapsed or refractory Hodgkin's lymphoma. We aimed to assess the safety and early clinical efficacy of this drug as first-line treatment in combination with standard or modified-standard treatment in patients with previously untreated Hodgkin's lymphoma. We did a phase 1, open-label, dose-escalation safety study comparing brentuximab vedotin in combination with standard (ABVD) or a modified-standard (AVD) treatment. Patients were enrolled into the groups sequentially. Main entry criteria were newly diagnosed, treatment-naive, CD30-positive patients with Hodgkin's lymphoma who had histologically confirmed stage IIA bulky disease or stage IIB–IV disease and an Eastern Cooperative Oncology Group performance status of two or less. Patients received doses of 0·6, 0·9, or 1·2 mg/kg brentuximab vedotin by intravenous infusion every 2 weeks with either ABVD (25 mg/m2 doxorubicin, 10 units/m2 bleomycin, 6 mg/m2 vinblastine, and 375 mg/m2 dacarbazine) or AVD (ABVD modified regimen without the inclusion of bleomycin) for up to six cycles. Our primary objectives were to assess the safety profile and establish the maximum tolerated dose (MTD) of brentuximab vedotin in combination with ABVD and AVD. The safety profile and MTD was assessed for the safety population. The study has completed and the final analysis is presented. This study was registered with ClinicalTrials.gov, number NCT01060904. Between Jan 29, 2010, and Sept 17, 2012, 51 patients were enrolled and received at least one dose of brentuximab vedotin. The maximum tolerated dose of brentuximab vedotin when combined with ABVD or AVD was not exceeded at 1·2 mg/kg. 21 (95%) of 22 patients given brentuximab vedotin and ABVD achieved complete remission, as did 24 (96%) of 25 patients given brentuximab vedotin and AVD. Adverse events were generally grade 1 or 2; however, an unacceptable number of patients in the brentuximab vedotin and ABVD groups had pulmonary toxic effects (11 [44%] of 25), which exceeded the historical incidence for ABVD alone. No patients experienced pulmonary toxic effects when treated with brentuximab vedotin plus AVD. The most common grade 3 or worse events were neutropenia (20 [80%] of 25 patients in the brentuximab vedotin and ABVD group vs 20 [77%] of 26 patients in the brentuximab vedotin and AVD group), anaemia (five [20%] vs three [12%]), febrile neutropenia (five [20%] vs two [8%]), pulmonary toxic effects (six [24%] vs 0), syncope (three [12%] vs two [8%]), dyspnoea (three [12%] vs one [4%]), pulmonary embolism (three [12%] vs 0), fatigue (one [4%] each), and leucopenia (one [4%] each). Serious events occured in 41% of all patients (14 [56%] in the brentuximab vedotin and ABVD group and seven [27%] in the brentuximab vedotin and AVD group). Serious events occurring in 10% of patients or more overall were febrile neutropenia (four [16%] in the brentuximab vedotin and ABVD group vs two [8%] in the brentuximab vedotin and AVD group), and, in the brentuximab vedotin and ABVD group only, pulmonary toxic effects (six [24%]). Brentuximab vedotin should not be given with bleomycin in general or specifically as first-line therapy for patients with treatment naive, advanced stage Hodgkin's lymphoma. 1·2 mg/kg brentuximab vedotin combined with AVD given every 2 weeks was generally well tolerated by patients. At present, a phase 3 trial comparing brentuximab vedotin plus AVD to ABVD alone is ongoing (ClinicalTrials.gov, number NCT01712490) and will formally assess whether brentuximab vedotin plus AVD might redefine therapy in treatment-naive patients with Hodgkin's lymphoma.

Trastuzumab resistance is a key therapeutic challenge in metastatic breast cancer. We postulated that broader inhibition of ErbB receptors with afatinib would improve clinical outcomes compared with HER2 inhibition alone in patients who had progressed on previous trastuzumab treatment. LUX-Breast 1 compared afatinib plus vinorelbine with trastuzumab plus vinorelbine for such patients with HER2-positive metastatic breast cancer. We did this open-label trial at 350 hospitals in 41 countries worldwide. We enrolled female patients with HER2-overexpressing metastatic breast cancer who had progressed on or following adjuvant trastuzumab or first-line treatment of metastatic disease with trastuzumab. Participants were randomly assigned (2:1) to receive oral afatinib (40 mg/day) plus intravenous vinorelbine (25 mg/m2 per week) or intravenous trastuzumab (2 mg/kg per week after 4 mg/kg loading dose) plus vinorelbine. Randomisation was done centrally and stratified by previous trastuzumab treatment (adjuvant vs first-line treatment), hormone receptor status (oestrogen receptor and progesterone receptor positive vs others), and region. The primary endpoint was progression-free survival, assessed in the intention-to-treat population. This trial is closed to enrolment and is registered with ClinicalTrials.gov, NCT01125566. Between Aug 26, 2010, and April 26, 2013, we enrolled 508 patients: 339 assigned to the afatinib group and 169 assigned to the trastuzumab group. Recruitment was stopped on April 26, 2013, after a benefit–risk assessment by the independent data monitoring committee was unfavourable for the afatinib group. Patients on afatinib plus vinorelbine had to switch to trastuzumab plus vinorelbine, afatinib monotherapy, vinorelbine monotherapy, or receive treatment outside of the trial. Median follow-up was 9·3 months (IQR 3·7–16·0). Median progression-free survival was 5·5 months (95% CI 5·4–5·6) in the afatinib group and 5·6 months (5·3–7·3) in the trastuzumab group (hazard ratio 1·10 95% CI 0·86–1·41; p=0·43). The most common drug-related adverse events of grade 3 or higher were neutropenia (190 [56%] of 337 patients in the afatinib group vs 102 [60%] of 169 patients in the trastuzumab group), leucopenia (64 [19%] vs 34 [20%]), and diarrhoea (60 [18%] vs none). Trastuzumab-based therapy remains the treatment of choice for patients with HER2-positive metastatic breast cancer who had progressed on trastuzumab. Boehringer Ingelheim.
