TL;DR: Ceritinib showed a significant improvement in median progression-free survival compared with chemotherapy and was compared with single-agent chemotherapy in patients with advanced ALK-rearranged non-small-cell lung cancer who had previously progressed following crizotinib and platinum-based doublet chemotherapy.
Abstract: Summary Background Ceritinib is a next-generation anaplastic lymphoma kinase (ALK) inhibitor, which has shown robust anti-tumour efficacy, along with intracranial activity, in patients with ALK -rearranged non-small-cell lung cancer. In phase 1 and 2 studies, ceritinib has been shown to be highly active in both ALK inhibitor-naive and ALK inhibitor-pretreated patients who had progressed after chemotherapy (mostly multiple lines). In this study, we compared the efficacy and safety of ceritinib versus single-agent chemotherapy in patients with advanced ALK -rearranged non-small-cell lung cancer who had previously progressed following crizotinib and platinum-based doublet chemotherapy. Methods In this randomised, controlled, open-label, phase 3 trial, we recruited patients aged at least 18 years with ALK -rearranged stage IIIB or IV non-small-cell lung cancer (with at least one measurable lesion) who had received previous chemotherapy (one or two lines, including a platinum doublet) and crizotinib and had subsequent disease progression, from 99 centres across 20 countries. Other inclusion criteria were a WHO performance status of 0–2, adequate organ function and laboratory test results, a life expectancy of at least 12 weeks, and having recovered from previous anticancer treatment-related toxicities. We randomly allocated patients (1:1; with blocking [block size of four]; stratified by WHO performance status [0 vs 1–2] and presence or absence of brain metastases) to oral ceritinib 750 mg per day fasted (in 21 day treatment cycles) or chemotherapy (intravenous pemetrexed 500 mg/m 2 or docetaxel 75 mg/m 2 [investigator choice], every 21 days). Patients who discontinued chemotherapy because of progressive disease could cross over to the ceritinib group. The primary endpoint was progression-free survival, assessed by a masked independent review committee using Response Evaluation Criteria in Solid Tumors 1.1 in the intention-to-treat population, assessed every 6 weeks until month 18 and every 9 weeks thereafter. This trial is registered with ClinicalTrials.gov, number NCT01828112, and is ongoing but no longer recruiting patients. Findings Between June 28, 2013, and Nov 2, 2015, we randomly allocated 231 patients; 115 (50%) to ceritinib and 116 (50%) to chemotherapy (40 [34%] to pemetrexed, 73 [63%] to docetaxel, and three [3%] discontinued before receiving treatment). Median follow-up was 16·5 months (IQR 11·5–21·4). Ceritinib showed a significant improvement in median progression-free survival compared with chemotherapy (5·4 months [95% CI 4·1–6·9] for ceritinib vs 1·6 months [1·4–2·8] for chemotherapy; hazard ratio 0·49 [0·36–0·67]; p vs 12 [11%] in the chemotherapy group). The most frequent grade 3–4 adverse events in the ceritinib group were increased alanine aminotransferase concentration (24 [21%] of 115 vs two [2%] of 113 in the chemotherapy group), increased γ glutamyltransferase concentration (24 [21%] vs one [1%]), and increased aspartate aminotransferase concentration (16 [14%] vs one [1%] in the chemotherapy group). Six (5%) of 115 patients in the ceritinib group discontinued because of adverse events compared with eight (7%) of 116 in the chemotherapy group. 15 (13%) of 115 patients in the ceritinib group and five (4%) of 113 in the chemotherapy group died during the treatment period (from the day of the first dose of study treatment to 30 days after the final dose). 13 (87%) of the 15 patients who died in the ceritinib group died because of disease progression and two (13%) died because of an adverse event (one [7%] cerebrovascular accident and one [7%] respiratory failure); neither of these deaths were considered by the investigator to be treatment related. The five (4%) deaths in the chemotherapy group were all due to disease progression. Interpretation These findings show that patients derive significant clinical benefit from a more potent ALK inhibitor after failure of crizotinib, and establish ceritinib as a more efficacious treatment option compared with chemotherapy in this patient population.

TL;DR: In this article, the authors investigated the role of IL-12Rbeta1-dependent signals in the development of human IL-17-producing T helper cells in vivo by quantifying the production and secretion of human interleukin (IL) 17 by fresh T cells ex vivo, and by T cell blasts expanded in vitro from patients with particular genetic traits affecting transforming growth factor (TGF) beta, IL-1, IL 6, or IL-23 responses.
Abstract: The cytokines controlling the development of human interleukin (IL) 17--producing T helper cells in vitro have been difficult to identify. We addressed the question of the development of human IL-17--producing T helper cells in vivo by quantifying the production and secretion of IL-17 by fresh T cells ex vivo, and by T cell blasts expanded in vitro from patients with particular genetic traits affecting transforming growth factor (TGF) beta, IL-1, IL-6, or IL-23 responses. Activating mutations in TGFB1, TGFBR1, and TGFBR2 (Camurati-Engelmann disease and Marfan-like syndromes) and loss-of-function mutations in IRAK4 and MYD88 (Mendelian predisposition to pyogenic bacterial infections) had no detectable impact. In contrast, dominant-negative mutations in STAT3 (autosomal-dominant hyperimmunoglobulin E syndrome) and, to a lesser extent, null mutations in IL12B and IL12RB1 (Mendelian susceptibility to mycobacterial diseases) impaired the development of IL-17--producing T cells. These data suggest that IL-12Rbeta1- and STAT-3--dependent signals play a key role in the differentiation and/or expansion of human IL-17-producing T cell populations in vivo.

TL;DR: An open-label study assessing the safety and efficacy of ledipasvir, sofosbuvir, and ribavirin in patients with HCV genotype 1 or 4 and advanced liver disease found high rates of sustained virological response 12 weeks after treatment.
Abstract: Summary Background Treatment options are limited for patients infected by hepatitis C virus (HCV) with advanced liver disease. We assessed the safety and efficacy of ledipasvir, sofosbuvir, and ribavirin in patients with HCV genotype 1 or 4 and advanced liver disease. Methods We did an open-label study at 34 sites in Europe, Canada, Australia, and New Zealand. Cohort A included patients with Child-Turcotte-Pugh class B (CTP-B) or CTP-C cirrhosis who had not undergone liver transplantation. Cohort B included post-transplantation patients who had either no cirrhosis; CTP-A, CTP-B, or CTP-C cirrhosis; or fibrosing cholestatic hepatitis. Patients in each group were randomly assigned (1:1) using a computer-generated randomisation sequence to receive 12 or 24 weeks of ledipasvir (90 mg) and sofosbuvir (400 mg) once daily (combination tablet), plus ribavirin (600–1200 mg daily). The primary endpoint was the proportion of patients achieving a sustained virological response 12 weeks after treatment (SVR12). All patients who received at least one dose of study drug were included in the safety analysis and all patients who received at least one dose of study drug and did not undergo liver transplantation during treatment were included in the efficacy analyses. Estimates of SVR12 and relapse rates and their two-sided 90% CI (Clopper-Pearson method) were provided. This exploratory phase 2 study was not powered for formal comparisons among treatment groups; no statistical hypothesis testing was planned or conducted. The trial is registered with EudraCT (number 2013-002802-30) and ClinicalTrials.gov (number NCT02010255). Findings Between Jan 14, 2014, and Aug 19, 2014, 398 patients were screened. Of 333 patients who received treatment, 296 had genotype 1 HCV and 37 had genotype 4 HCV. In cohort A, among patients with genotype 1 HCV, SVR12 was achieved by 20 (87%, 90% CI 70–96) of 23 CTP-B patients with 12 weeks of treatment; 22 (96%, 81–100) of 23 CTP-B patients with 24 weeks of treatment; 17 (85%, 66–96) of 20 CTP-C patients (12 weeks treatment); and 18 (78%, 60–91) of 23 CTP-C patients (24 weeks treatment). In cohort B, among patients with genotype 1 HCV, SVR12 was achieved by 42 (93%, 84–98) of 45 patients without cirrhosis (12 weeks treatment); 44 (100%, 93–100) of 44 patients without cirrhosis (24 weeks treatment); 30 (100%, 91–100) of 30 CTP-A patients (12 weeks treatment); 27 (96%, 84–100) of 28 CTP-A patients (24 weeks treatment); 19 (95%, 78–100) of 20 CTP-B patients (12 weeks treatment); 20 (100%, 86–100) of 20 CTP-B patients (24 weeks treatment); one (50%, 3–98) of two CTP-C patients (12 weeks treatment); and four (80%, 34–99) of five CTP-C patients (24 weeks treatment). All five patients with fibrosing cholestatic hepatitis achieved SVR12 (100%, 90% CI 55–100). Among all patients with genotype 4 HCV, SVR12 was achieved by 14 (78%, 56–92) of 18 patients (12 weeks treatment) and 16 (94%, 75–100) of 17 patients (24 weeks treatment). Seven patients (2%) discontinued ledipasvir–sofosbuvir prematurely due to adverse events. 17 patients died, mainly from complications of hepatic decompensation. Interpretation Ledipasvir–sofosbuvir and ribavirin provided high rates of SVR12 for patients with advanced liver disease, including those with decompensated cirrhosis before or after liver transplantation.

TL;DR: Administering higher doses on a 3-weekly schedule did not compromise the efficacy and safety of trastuzumab in women with HER2-positive MBC, and average exposure was similar to that observed with weekly therapy.
Abstract: Purpose This phase II study investigated the efficacy, safety, and pharmacokinetics of trastuzumab monotherapy given as first-line treatment once every 3 weeks (3-weekly) in women with human epidermal growth factor receptor 2 (HER2) -positive metastatic breast cancer (MBC). Patients and Methods Patients with previously untreated HER2-positive MBC received a loading dose of trastuzumab, 8 mg/kg intravenously (IV) and then 6 mg/kg IV at 3-week intervals until disease progression or patient withdrawal. Results In total, 105 patients received a median of five cycles of therapy (range, 1 to 35+). The overall response rate was 19% (23% in patients with measurable centrally confirmed immunohistochemistry [IHC] 3+ and/or fluorescence in situ hybridization [FISH] -positive disease) and clinical benefit rate (complete and partial responses plus stable disease for at least 6 months) was 33% (36% in patients with measurable centrally confirmed IHC 3+ and/or FISH-positive disease). Median time to progression was 3.4 m...

TL;DR: These results show a sustained benefit in event-free survival from trastuzumab-containing neoadjuvant therapy followed by adjuvant trastzumab in patients with locally advanced or inflammatory breast cancer, and provide new insight into the association between pathological complete remission and long-term outcomes in HER2-positive disease.
Abstract: Summary Background In our randomised, controlled, phase 3 trial NeOAdjuvant Herceptin (NOAH) trial in women with HER2-positive locally advanced or inflammatory breast cancer, neoadjuvant trastuzumab significantly improved pathological complete response rate and event-free survival. We report updated results from our primary analysis to establish the long-term benefit of trastuzumab-containing neoadjuvant therapy. Methods We did this multicentre, open-label, randomised trial in women with HER2-positive locally advanced or inflammatory breast cancer. Participants were randomly assigned (1:1), by computer program with a minimisation technique, to receive neoadjuvant chemotherapy alone or with 1 year of trastuzumab (concurrently with neoadjuvant chemotherapy and continued after surgery). A parallel group with HER2-negative disease was included and received neoadjuvant chemotherapy alone. Our primary endpoint was event-free survival. Analysis was by intention to treat. This study is registered at www.controlled-trials.com, ISRCTN86043495. Findings Between June 20, 2002, and Dec 12, 2005, we enrolled 235 patients with HER2-positive disease, of whom 118 received chemotherapy alone and 117 received chemotherapy plus trastuzumab. 99 additional patients with HER2-negative disease were included in the parallel cohort. After a median follow-up of 5·4 years (IQR 3·1–6·8) the event-free-survival benefit from the addition of trastuzumab to chemotherapy was maintained in patients with HER2-positive disease. 5 year event-free survival was 58% (95% CI 48–66) in patients in the trastuzumab group and 43% (34–52) in those in the chemotherapy group; the unadjusted hazard ratio (HR) for event-free survival between the two randomised HER2-positive treatment groups was 0·64 (95% CI 0·44–0·93; two-sided log-rank p=0·016). Event-free survival was strongly associated with pathological complete remission in patients given trastuzumab. Of the 68 patients with a pathological complete response (45 with trastuzumab and 23 with chemotherapy alone), the HR for event-free survival between those with and without trastuzumab was 0·29 (95% CI 0·11–0·78). During follow-up only four cardiovascular adverse events were regarded by the investigator to be drug-related (grade 2 lymphostasis and grade 2 lymphoedema, each in one patient in the trastuzumab group, and grade 2 thrombosis and grade 2 deep vein thrombosis, each in one patient in the chemotherapy-alone group). Interpretation These results show a sustained benefit in event-free survival from trastuzumab-containing neoadjuvant therapy followed by adjuvant trastuzumab in patients with locally advanced or inflammatory breast cancer, and provide new insight into the association between pathological complete remission and long-term outcomes in HER2-positive disease.
