Développement d'une méthode de recherche de dose modélisant un score de toxicité pour les essais cliniques de phase I en OncologieEzzalfani Gahlouzi, Monia 02 October 2013 (has links) (PDF)
Le but principal d'un essai de phase I en oncologie est d'identifier, parmi un nombre fini de doses, la dose à recommander d'un nouveau traitement pour les évaluations ultérieures, sur un petit nombre de patients.Le critère de jugement principal est classiquement la toxicité. Bien que la toxicité soit mesurée pour différents organes sur une échelle gradée, elle est généralement réduite à un indicateur binaire appelé "toxicité dose-limitante" (DLT). Cette simplification très réductrice est problématiqu, en particulier pour les thérapies, dites "thérapies ciblées", associées à peu de DLTs.Dans ce travail, nous proposons un score de toxicité qui résume l'ensemble des toxicités observées chez un patient. Ce score, appelé TTP pour Total Toxicity Profile, est défini par la norme euclidienne des poids associés aux différents types et grades de toxicités possibles. Les poids reflètent l'importance clinique des différentes toxicités.\\ Ensuite, nous proposons la méthode de recherche de dose, QLCRM pour Quasi-Likelihood Continual Reassessment Method, modélisant la relation entre la dose et le score de toxicité TTP à l'aide d'une régression logistique dans un cadre fréquentiste.A l'aide d'une étude de simulation, nous comparons la performance de cette méthode à celle de trois autres approches utilisant un score de toxicité : i) la méthode de Yuan et al. (QCRM) basée sur un modèle empirique pour estimer, dans un cadre bayésien, la relation entre la dose et le score, ii) la méthode d'Ivanova et Kim (UA) dérivée des méthodes algorithmiques et utilisant une régression isotonique pour estimer la dose à recommander en fin d'essai, iii) la méthode de Chen et al. (EID) basée sur une régression isotonique pour l'escalade de dose et l'identification de la dose à recommander. Nous comparons ensuite ces quatre méthodes utilisant le score de toxicité aux méthodes CRM basées sur le critère binaire DLT. Nous étudions également l'impact de l'erreur de classement des grades pour les différentes méthodes, guidées par le score de toxicité ou par la DLT.Enfin, nous illustrons le processus de construction du score de toxicité ainsi que l'application de la méthode QLCRM dans un essai réel de phase I. Dans cette application, nous avons utilisé une approche Delphi pour déterminer avec les cliniciens la matrice des poids et le score de toxicité jugé acceptable.Les méthodes QLCRM, QCRM, UA et EID présentent une bonne performance en termes de capacité à identifier correctement la dose à recommander et de contrôle du surdosage. Dans un essai incluant 36 patients, le pourcentage de sélection correcte de la dose à recommander obtenu avec les méthodes QLCRM et QCRM varie de 80 à 90% en fonction des situations. Les méthodes basées sur le score TTP sont plus performantes et plus robustes aux erreurs de classement des grades que les méthodes CRM basées sur le critère binaire DLT.Dans l'application rétrospective, le processus de construction du score apparaît faisable facilement. Cette étude nous a conduits à proposer des recommandations pour guider les investigateurs et faciliter l'utilisation de cette approche dans la pratique.En conclusion, la méthode QLCRM prenant en compte l'ensemble des toxicités s'avère séduisante pour les essais de phase I évaluant des médicaments associés à peu de DLTs a priori, mais avec des toxicités multiples modérées probables.

Previous issue date: 21 / Nenhuma / Competir deixou de ser somente a disputa pelo mercado para tornar-se fator de sobrevivência para a grande maioria das empresas. As organizações devem estabelecer e colocar
em prática estratégias, o mais rapidamente possível, para manter-se em seu mercado. A Tecnologia da Informação e Comunicação (TIC) é ferramenta essencial para o posicionamento estratégico, pois fornece um maior detalhamento das informações disponíveis, com maior
agilidade. Aliado a isso, a aplicação de uma estratégia de fidelização dos clientes rentáveis à empresa, também conhecida como estratégia de CRM (Customer Relationship Management) possibilita uma redução nos custos com captação de novos clientes, além do conhecimento mais
aprofundado das preferências e costumes dos atuais clientes. Porém, mesmo com a unificação da TIC, através dos sistemas de CRM com a busca pela fidelização dos clientes, diversas empresas estão tendo dificuldades em sua utilização. Os principais fatores que impossibilitam o sucesso no uso não se referem a fatore / Competition is no longer just the fight for market share. It became critical factor for the survival of most companies. Organizations must establish strategies and put them into practice as soon as possible to survive in their markets. The Technology of Information and Communication (TIC) is an essential tool for the strategic positioning because it provides more detail regarding information available, with more agility. In addition, the implementation of a strategy to increase the loyalty of profitable costumers, known as Customer Relationship Management (CRM), makes it possible cost reductions through the acquisition of new costumers and in-depth knowledge of current costumers’ preferences and habits. However, despite the integration of the TIC, through the systems of CRM with the goal of increased costumer loyalty, many companies are finding it difficult to use it. The main factors that prevent the success of the use of such tool are not technical, as, for instance, systems or equipments, but are related t

An examination of implementing customer relationship management by Chinese-owned SMEsLin, C. Y. January 2007 (has links)
In the last decade, the ever increasing pressure of competition faced by businesses has led to the development of Customer Relationship Management (CRM). In short, CRM is the practice of integrating all aspects of business functions for dealing with customers, with the assistance of technology, and with the intention of boosting company profitability. CRM has been widely promoted as a critical contributor to business survival. However, the high failure rate of CRM projects has also attracted research attention and many factors have been discussed as contributing to the success or failure of CRM implementation. This research argues that CRM is not simply a software package or a computer program. CRM, instead, should be perceived as a strategic issue in order to realize its potential. In addition, this study also argues that CRM implementation is affected by organizational, strategic and cultural factors. In particular, this study was conducted within the context of Chinese small and medium-size enterprises (SMEs), with company size and culture as two major focuses in this study. SMEs were chosen as this segment has been overlooked in CRM study, yet it represents a great potential for growth in CRM adoption. Chinese culture was chosen as most of CRM studies have been conducted within a western cultural background. The Chinese culture has distinctive characteristics different from western culture, and this has strong influences on business operations. A quantitative method was adopted for this study and a mailed survey was used to collect data to examine the relevance of these factors within this context. Research participants were recruited using a systematic sampling technique through a comprehensive Chinese business directory. Results suggest that there are positive associations between a company's CRM implementation and its practice of organizational, strategic, and cultural issues. In particular, four organizational issues – organizational integration, executive commitment, system readiness, and resource availability; three strategic issues – vision, planning, and customer-centric culture; and one cultural issue – networking, have an impact on a company's CRM implementation.

擔保房貸憑證(CMOs)評價---以BGM利率模型為例 / Pricing of the Collateralized Mortgage Obligations(CMOs)--Based on the Interest Rate Model of BGM張繼文, Chi-Wen Chang Unknown Date (has links)
擔保房貸憑證(CMOs)是衍生自不動產抵押證券(MBS)的證券化商品,透過分券的特殊設計,藉此降低MBS商品的提前清償風險,也增加市場投資人的選擇彈性。但特殊的設計同時也提高了評價上的困難度,由於此產品的提前清償狀況會依分券性質與標的抵押貸款借款人的償還情形而有所不同,為了準確掌握CMOs商品的現金流量,必須採用較為充分的貸款資料與提前清償模型來推估提前清償機率。本文採用競爭風險模型來做為提前清償模型,透過較多變數的選擇方式,模擬出較為精確的提前清償機率路徑。
此外,BGM利率模型是透過將利率間斷化,捕捉市場上可觀察到的利率,同時也可提供在不同時點下的即期利率,可藉此推算出不同時點下的分券價格,故採用BGM來做為本文的利率模型。
