This study will evaluate the efficacy and safety of atezolizumab compared with placebo as adjuvant therapy after definitive local therapy in patients with high-risk locally advanced squamous cell carcinoma of the head and neck (SCCHN)
The primary purpose of the study was to compare the efficacy and safety of canakinumab versus placebo as adjuvant therapy in adult subjects with stages II -IIIA according to the 8th edition of the American Joint Committee on Cancer (AJCC)/Union for International Cancer Control (UICC) and the subset of IIIB (T>5cm N2 disease) completely resected (R0) non-small cell lung cancer (NSCLC).
This randomized, double-blind, placebo-controlled, parallel group study will evaluate the efficacy and safety of gantenerumab versus placebo in participants with early (prodromal to mild) AD. All participants must show evidence of beta-amyloid pathology. Eligible participants will be randomized 1:1 to receive either subcutaneous (SC) injection of gantenerumab or placebo. The primary efficacy assessment will be performed at the end of the double blind period at week 116. Participants will then be offered to enter into an open-label extension (OLE). Participants not willing to go to the OLE will participate in a long term follow-up period for up to 50 weeks after the last gantenerumab dose.
This is a randomized, double-blind, placebo-controlled study comparing the safety and efficacy of 2 dosage regimens of palovarotene versus placebo in preventing disease progression in pediatric subjects with multiple osteochondromas (MO).
TNBC, defined by the lack of immunohistochemical staining for oestrogen receptors, progesterone receptors, and lack of overexpression or amplification of HER2/neu, has an aggressive biological behaviour, marked by increased risk of recurrence and poorer survival compared with hormone receptor-positive subtypes. The key points for the rationale of the present study are: 1. Despite different efforts for improving the outcome of TNBC patients, the median distant-disease free interval for relapsed triple-negative breast cancer is about 1-2 years, and the median survival for metastatic TNBC is approximately one year. 2. International guidelines currently recommend polychemotherapy instead of sequential single agents as first-line treatment in this subgroup of patients, but no data is available at the moment regarding the optimal duration of chemotherapy. 3. There is growing evidence to suggest that platinum-based therapy may have a role in both advanced and early-stage TNBC, though results are not definitive. Three randomized phase II neoadjuvant trials have been reported, two of which demonstrated an improvement in pathological complete response (pCR) rates when carboplatin is added to anthracycline and taxane-based chemotherapy, though this pCR improvement came at the cost of an increase in toxicity. Definitive results from phase III trials demonstrating improvement in long-term outcomes such as event-free and overall survival are not yet available, and it remains unclear how to optimally incorporate platinums into neoadjuvant therapy, as toxicity is enhanced when platinum is incorporated as an add-on to standard combination chemotherapy backbones. A randomized phase III trial comparing cisplatin plus gemcitabine to paclitaxel plus gemcitabine has been published recently. After a median follow-up of 16.3 months in the cisplatin plus gemcitabine group and 15.9 months in the paclitaxel plus gemcitabine group, the hazard ratio for progression-free survival was 0.692 (95% CI 0•523-0•915; pnon-inferiority<0•0001, superiority=0•009. Thus cisplatin plus gemcitabine was both non-inferior to and superior to paclitaxel plus gemcitabine. Median progression-free survival was 7.7 months (95% CI 6.2-9.3) in the cisplatin plus gemcitabine group and 6.5 months (5.8-7.2) in the paclitaxel plus gemcitabine group. 4. In both early and advanced disease settings, response rates appear to be influenced by germ line BRCA1 and BRCA2 mutation status, and BRCA1 and BRCA2 mutation status has emerged as an important potential biomarker for platinum therapy. Outside of the BRCA mutant setting, there is certainly good reason to believe that there are patients with sporadic TNBC who stand to benefit greatly from a platinum-based approach. Tumour-based assays that detect levels of genomic scarring caused by the accumulation of DNA damage over time secondary to underlying DNA repair defects, such as the Myriad HRD assay, have potential to identify non carriers of BRCA1 or BRCA2 mutations with "BRCA-like" breast cancer, who may respond to DNA repair- targeted treatment strategies, such as platinum agents. One of the most promising way to improve clinical outcome in poor-risk patients is represented by maintenance therapy with a non-cross resistant regimen after an induction treatment, until disease progression. Nevertheless, the main limit to such a strategy is the choice of chemotherapy agents, considering that patients could be treated for a long period of time The results of the VICTOR-1 study was recently published, the aim of this study was the determination of the maximum tolerated dose of oral metronomic schedule of vinorelbine (VNR) in combination with fixed doses of capecitabine (CAPE), as well as to confirm the safety profile of the combination in a cohort of HER2-negative metastatic breast cancer patients. The results demonstrated a lower incidence of hematological grade 3-4 adverse events (1.1%), in comparison to what published in other series, using the standard schedules of the two drugs. The present study is designed to select the best arm between oral metronomic schedule of vinorelbine (VNR) and combination of oral metronomic schedule VNR with fixed doses of capecitabine (CAPE) as maintenance therapy in advanced TNBC patients responders after an induction treatment.
This is a phase 2, multicenter, randomized, double-blind, placebo-controlled, dose-finding study to evaluate the efficacy and safety of IMU-838 for induction and maintenance therapy with an option for open-label treatment extension in moderate-to-severe ulcerative colitis (CALDOSE-1).
A Phase 1, open-label study of intravenous (IV) PRX004 as a single agent in subjects with hereditary amyloid transthyretin (hATTR) amyloidosis. The study will consist of 3 phases and will enroll up to a total of 36 subjects. A 3+3 dose escalation component to determine the safety, tolerability, PK, PD, and MTD. An expansion component in anticipated PRX004 RP2D cohorts selected from the Dose Escalation Phase. An extended dosing component for eligible subjects from the Dose Escalation or Expansion phases.
