Abstract:
Background Bayesian statistics are an appealing alternative to the traditional frequentist approach to designing, analysing, and reporting of clinical trials, especially in rare diseases. Time-to-event endpoints are widely used in many medical fields. There are additional complexities to designing Bayesian survival trials which arise from the need to specify a model for the survival distribution. The objective of this article was to critically review the use and reporting of Bayesian methods in survival trials. Methods A systematic review of clinical trials using Bayesian survival analyses was

Abstract:
Before a first-in-man trial is conducted, preclinical studies are performed in animals to help characterise the safety profile of the new medicine. We propose a robust Bayesian hierarchical model to synthesise animal and human toxicity data, using scaling factors to translate doses administered to different animal species onto an equivalent human scale. After scaling doses, the parameters of dose-toxicity models intrinsic to different animal species can be interpreted on a common scale. A prior distribution is specified for each translation factor to capture uncertainty about differences betwe

Abstract:
TPS145 Background: Although most cancers are initially susceptible to existing anticancer therapies, over time cancer cells develop resistance. BOLD-100 is a first-in-class therapy that targets the GRP78 pathway, a major regulator of cellular stress and resistance. This therapy suppresses drug resistance, survival and proliferation by restraining stress-induced upregulation of GRP78 in tumor cells, leading to inhibition of the cell survival response. BOLD-100 successfully completed a Phase 1 monotherapy trial, with a manageable safety profile; it has demonstrated synergy in established preclin

Summary Objectives: The aim of this paper is to show that even in a highly regulated area such as clinical research and development in pharmaceutical industry, there are needs and ample opportunities for statisticians and other medical informatics professionals to further creatively develop and implement methods in order to support the collection, analysis and interpretation of clinical data.

Abstract:
Background: The outcome of patients with blast phase chronic myeloid leukaemia (CML) remains extremely poor despite the advent of tyrosine kinase inhibitors (TKIs), and the majority of blast phase patients have already failed the currently licensed TKIs during the chronic phase. Currently there is no standard therapy for patients with blast phase CML, but most will receive 2 or 3 courses of chemotherapy or a TKI, followed by stem cell transplantation (alloSCT). In the PACE clinical trial of ponatinib, 23% of patients with blast phase CML achieved major cytogenetic response, with overall surviv

Abstract:
Abstract Background: Omacetaxine mepesuccinate (OM) is a semi-synthetic form of Homoharringtonine (HH), a cephalotaxine alkaloid. OM induces cell apoptosis by inhibiting peptide bond formation during mRNA translation, with rapid loss of short-lived proteins, such as MCL-1, c-MYC, and Cyclin D1 (Lu, J Hematol Oncol. 2014, 7: 2). Notably, cytarabine synergizes with HH in causing apoptosis of leukemia cells in vitro. A phase III RCT in China of 620 patients with de novo AML demonstrated superior CR and 3-yr survival rates upon addition of HH to a standard 2-drug AML induction therapy ('7 + 3'; Ji

Abstract Background: The prognosis of patients with lower-risk MDS is heterogeneous; many have poor survival (Leukemia. 2008;22:538-543). Hypomethylating agents (HMA) improve the outcomes of patients with higher-risk MDS. Recent Phase I/II studies suggested that HMA doses below current standards of care retain activity in MDS, potentially with a better toxicity profile (JCO. 2009;27:1850-1856). We hypothesized that lower doses of HMA may be active and well tolerated in patients with lower-risk MDS.

Abstract:
Abstract Cancer tissue samples obtained via biopsy or surgery were examined for specific gene mutations by genetic testing to inform treatment. Precision medicine, which considers not only the cancer type and location, but also the genetic information, environment, and lifestyle of each patient, can be applied for disease prevention and treatment in individual patients. The number of patient-specific characteristics, including biomarkers, has been increasing with time; these characteristics are highly correlated with outcomes. The number of patients at the beginning of early-phase clinical tri
