Evaluating the effectiveness of interventions in real-world settings is complex and demands a rethinking of the traditional clinical trial approach as well as transformation of the clinical trial landscape. Novel strategies and refinement of existing approaches have been proposed to generate evidence that can guide health care stakeholders in their decision process. The purpose of this review is to discuss clinical trial design approaches in the era of comparative effectiveness research. We will focus on aspects relevant to the type of clinical trial, study population and recruitment, randomization process, outcome measures, and data collection.","PeriodicalId":19500,"journal":{"name":"Open Access Journal of Clinical Trials","volume":"6 1","pages":"101-110"},"PeriodicalIF":1.2,"publicationDate":"2014-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2147/OAJCT.S39758","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68414058","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Larsen","doi":"10.2147/OAJCT.S57955","DOIUrl":"https://doi.org/10.2147/OAJCT.S57955","url":null,"abstract":"Background: The most commonly used escalation methods in dose-finding studies have obvious weaknesses, and the Bayesian approach is difficult for clinicians to understand and to apply. The study aims were to introduce and assess the performance of clinically based response surface pathway (RSP) design for dose-finding studies, exemplified by one between-patient study, one within-patient study, and simulation studies. Methods: The between-patient study consisted of 15 women suffering from stage IV breast cancer, while the within-patient study consisted of seven female dogs with metastatic mammary cancer. The studies were conducted to determine the maximum tolerated dose (MTD) of a new anticancer agent named BP-C1 using three-level RSP designs. Adjustment of the dose from one design level to the next was based on a k -adjustment factor estimated to ensure coverage of the entire predefined dose window. Patient sequences with an equal number of patients as design levels were included in the between-patient design, whereas the same patients were included in all the design levels in the within-patient design. Results: Four of the five patient sequences in the between-patient study and all seven dogs in the within-patient study reached the upper limit of the dose windows without any increase in toxicity. The MTD of BP-C1 was thus found to be higher than the predefined cumulative dose window for both patient groups. In all three scenarios, the RSP design estimated MTDs better than the traditional 3 + 3 design; however, the toxicity rates were found to be higher when the target MTD was under the starting dose. Conclusion: The RSP designs do not need an assumed statistical model, and may be useful in estimating MTD, using a minimal sample size. The k -adjustment factor ensures complete dose window coverage and the design utilizes more information by allowing multinomial outcomes. Phase I studies are conducted sequentially, allocating dose levels to patients based on the observed toxicity effect from previous patients or treatment periods.","PeriodicalId":19500,"journal":{"name":"Open Access Journal of Clinical Trials","volume":"6 1","pages":"63-74"},"PeriodicalIF":1.2,"publicationDate":"2014-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2147/OAJCT.S57955","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68414935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Regulatory bodies and expert panels in the USA and Europe have recognized that both acute rejection and one-year graft function should be assessed when evaluating immunosuppressive regimens. TRANSFORM (Clinicaltrials.gov NCT01950819) is one of the first trials to adopt this approach and the first that applies a novel combined clinically meaningful endpoint to take the first step towards changing the paradigm for immunosuppression in kidney transplant patients. Everolimus with reduced-exposure calcineurin inhibitor (CNI) therapy is a strategy designed to reduce the risk of chronic nephrotoxicity and other dose-dependent complications associated with CNI therapy. In TRANSFORM, de novo kidney transplant patients are randomized to everolimus with reduced-exposure CNI, or mycophenolic acid with standard-exposure CNI, both with induction therapy and maintenance steroids. The primary endpoint is a composite of treated biopsy-proven acute rejection or estimated glomerular filtration rate ,50 mL/min/1.73 m 2 at month 12 post-transplant, which is expected to be sensitive both to the effects of acute and chronic allograft rejection and nephrotoxic side effects of immunosuppressive therapies. The construct of this endpoint allows the integration of a continuous outcome (graft function) with a logistic outcome (rejection). The trial uses a randomized, multicenter, open-label, two-arm design. After completion of a 2-year core study, patients enter a further 3-year prospective observational study. By capturing follow-up to 5 years, TRANSFORM will provide substantial data on the incidence of graft loss, graft dysfunction, cancer, cardiovascular events, and other patient-relevant outcomes. TRANSFORM will determine whether de novo CNI reduction with an everolimus-based regimen achieves short-term outcomes compared with standard CNI. As the largest clinical trial undertaken to date in kidney transplantation, recruiting more than 2,000 patients, and with extended follow-up to 5 years, TRANSFORM will provide critical data required to help maximize long-term outcomes.","PeriodicalId":19500,"journal":{"name":"Open Access Journal of Clinical Trials","volume":"6 1","pages":"45-54"},"PeriodicalIF":1.2,"publicationDate":"2014-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2147/OAJCT.S63058","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68414891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
