Book Description
An ideal health care system relies on efficiently generating timely, accurate evidence to deliver on its promise of diminishing the divide between clinical practice and research. There are growing indications, however, that the current health care system and the clinical research that guides medical decisions in the United States falls far short of this vision. The process of generating medical evidence through clinical trials in the United States is expensive and lengthy, includes a number of regulatory hurdles, and is based on a limited infrastructure. The link between clinical research and medical progress is also frequently misunderstood or unsupported by both patients and providers. The focus of clinical research changes as diseases emerge and new treatments create cures for old conditions. As diseases evolve, the ultimate goal remains to speed new and improved medical treatments to patients throughout the world. To keep pace with rapidly changing health care demands, clinical research resources need to be organized and on hand to address the numerous health care questions that continually emerge. Improving the overall capacity of the clinical research enterprise will depend on ensuring that there is an adequate infrastructure in place to support the investigators who conduct research, the patients with real diseases who volunteer to participate in experimental research, and the institutions that organize and carry out the trials. To address these issues and better understand the current state of clinical research in the United States, the Institute of Medicine's (IOM) Forum on Drug Discovery, Development, and Translation held a 2-day workshop entitled Transforming Clinical Research in the United States. The workshop, summarized in this volume, laid the foundation for a broader initiative of the Forum addressing different aspects of clinical research. Future Forum plans include further examining regulatory, administrative, and structural barriers to the effective conduct of clinical research; developing a vision for a stable, continuously funded clinical research infrastructure in the United States; and considering strategies and collaborative activities to facilitate more robust public engagement in the clinical research enterprise.

Cancer Chemotherapy: Concepts, Clinical Investigations and Therapeutic Advances
Author: Franco M. Muggia
Publisher: Springer Science & Business Media
ISBN: 1461317479
Category : Medical
Languages : en
Pages : 235
Book Description
Experimental chemotherapy continues to be at the forefront of cancer thera peutics. Topics covered in the preceding volume on cancer chemotherapy in this series such as study of drugs by alkaline elution, the development of the antimetabolite tiazofurin, and the treatment of germ cell tumors have become informative references to current experimentalists and practitioners. In even earlier volumes, reviews of the platinum compounds, anthracyclines, and osteosarcoma represent topics associated with such rapid progress requiring a look back to provide the appropriate perspective. Similarly, we venture to predict that the topics in this volume will become useful landmarks for future drug development and disease strategies. In the area of drug development, what is being learned about old, estab lished antineoplastics is raising renewed expectations that it will be translated into improved applications and patient benefit. For example, we now have the ability to modulate the action of alkylating agents and fluorinated pyri midines to achieve greater sensitivity. A new compound for an old target, trimetrexate, an antifolate that does not polyglutaminate, will have a role not only in treatment of neoplastic diseases, but also protozoal infection.

The Prevention and Treatment of Missing Data in Clinical Trials
Author: National Research Council
Publisher: National Academies Press
ISBN: 030918651X
Category : Medical
Languages : en
Pages : 163
Book Description
Randomized clinical trials are the primary tool for evaluating new medical interventions. Randomization provides for a fair comparison between treatment and control groups, balancing out, on average, distributions of known and unknown factors among the participants. Unfortunately, these studies often lack a substantial percentage of data. This missing data reduces the benefit provided by the randomization and introduces potential biases in the comparison of the treatment groups. Missing data can arise for a variety of reasons, including the inability or unwillingness of participants to meet appointments for evaluation. And in some studies, some or all of data collection ceases when participants discontinue study treatment. Existing guidelines for the design and conduct of clinical trials, and the analysis of the resulting data, provide only limited advice on how to handle missing data. Thus, approaches to the analysis of data with an appreciable amount of missing values tend to be ad hoc and variable. The Prevention and Treatment of Missing Data in Clinical Trials concludes that a more principled approach to design and analysis in the presence of missing data is both needed and possible. Such an approach needs to focus on two critical elements: (1) careful design and conduct to limit the amount and impact of missing data and (2) analysis that makes full use of information on all randomized participants and is based on careful attention to the assumptions about the nature of the missing data underlying estimates of treatment effects. In addition to the highest priority recommendations, the book offers more detailed recommendations on the conduct of clinical trials and techniques for analysis of trial data.

Advances in Cancer Treatment
Author: Iago Dillion Lima Cavalcanti
Publisher: Springer Nature
ISBN: 3030683346
Category : Medical
Languages : en
Pages : 109
Book Description
This work covers the pathophysiology of cancer, exploring the difficulty of optimal treatment due to the complexity and diversity of cancer types. The search for distinctive molecular biology characteristics of tumor cells is especially relevant in the identification of overexpressed receptors and proteins that can be used as a target for cancer treatment. We highlight the main therapeutic modalities, particularly conventional systemic chemotherapy, addressing its mechanisms of action, therapeutic classes and even the toxic effects. We also describe the main tumor markers, their importance in the diagnosis and treatment of cancer, and the specificity of tumor cells. The first chapters serve as an introduction to the central topic of this book, targeted therapy. Key aspects of target therapy, such as classes of drugs, immunotherapy, monoclonal antibodies, checkpoint inhibitors, cancer vaccines and tyrosine kinase inhibitors are presented, and, for each one, the benefits, as well as the adverse effects are reported. Chapter 6 compares conventional systemic chemotherapy and targeted therapy, identifies the risks and benefits and also the eligibility criteria for patient care. The possibility of targeted therapy replacing conventional chemotherapy is discussed while reviewing studies that demonstrate the benefits of combining both types of treatment. Finally, the introduction of pharmaceutical nanotechnology to improve antineoplastic agents is addressed in the last chapter and sets the direction for future research in cancer treatment. This is a valuable resource for many health professionals including physicians, pharmacists, nurses, researchers and students interested in the field of oncology.

Small Clinical Trials
Author: Institute of Medicine
Publisher: National Academies Press
ISBN: 0309171148
Category : Medical
Languages : en
Pages : 221
Book Description
Clinical trials are used to elucidate the most appropriate preventive, diagnostic, or treatment options for individuals with a given medical condition. Perhaps the most essential feature of a clinical trial is that it aims to use results based on a limited sample of research participants to see if the intervention is safe and effective or if it is comparable to a comparison treatment. Sample size is a crucial component of any clinical trial. A trial with a small number of research participants is more prone to variability and carries a considerable risk of failing to demonstrate the effectiveness of a given intervention when one really is present. This may occur in phase I (safety and pharmacologic profiles), II (pilot efficacy evaluation), and III (extensive assessment of safety and efficacy) trials. Although phase I and II studies may have smaller sample sizes, they usually have adequate statistical power, which is the committee's definition of a "large" trial. Sometimes a trial with eight participants may have adequate statistical power, statistical power being the probability of rejecting the null hypothesis when the hypothesis is false. Small Clinical Trials assesses the current methodologies and the appropriate situations for the conduct of clinical trials with small sample sizes. This report assesses the published literature on various strategies such as (1) meta-analysis to combine disparate information from several studies including Bayesian techniques as in the confidence profile method and (2) other alternatives such as assessing therapeutic results in a single treated population (e.g., astronauts) by sequentially measuring whether the intervention is falling above or below a preestablished probability outcome range and meeting predesigned specifications as opposed to incremental improvement.
