- Description
- DESC: The National Cancer Institute, Division of Cancer Prevention, (DCP) Chemoprevention Agent Development Research Group (CADRG) is interested in conducting animal cancer model studies of biomarkers and intermediate endpoints that might be used in human clinical trials in order to examine in detail the biomarker modulating effects of selected chemopreventive compounds. In addition the studies will improve biomarker sensitivity, specificity, assay methodology, and sample handling. The emphasis will be on efficient studies aimed at providing more quantitative, and more validated intermediate endpoints for future human clinical trials. Intermediate endpoints or biomarkers that are directly associated with the evolution of neoplasia, and that develop with much higher frequency in abnormal cells of susceptible individuals than do the actual tumors, will make it possible in the future to carry out many studies on fewer subjects for shorter durations. If such biomarkers were found to be modified by a particular intervention regimen in preclinical studies, a rationale would be provided for carrying out clinical studies. The application of biological markers to clinical cancer prevention trials carries great promise in relation to ultimate cancer prevention. When neoplasia itself is used as an end point in studies of this type, a very large number of subjects tested for long durations are often required. The results of these in vivo experiments will be used to select promising intermediate endpoints for Phase II human studies whose objectives are to study the modulation of a selected biomarker in response to a chemopreventive agent. These relevant preclinical studies will be used to help achieve one of the major goals of the chemoprevention program which is the timely evaluation of chemopreventive agents in clinical trials. A number of chemical compounds and/or dietary components have been shown to inhibit carcinogenesis in animal models, in vitro systems, and to be associated with cancer reduction in epidemiological studies. Results from animal studies suggest that a number of compounds and/or dietary components may affect several stages of carcinogenesis. A variety of excellent biomarkers are now available. Examples include reversal of abnormal cytology, ornithine decarboxylase activity, prostaglandin synthetase inhibition, DNA ploidy alterations, changes in cellular proliferation (e.g., tritiated thymidine or BrdU labeling indices, decreases in PCNA or Ki-67 antigens, or histology), and oncogene suppression tests. The development and utilization of sensitive and accurate intermediate endpoints should enhance the ability to design effective human Phase II clinical trials. This RFP will involve nine (9) workstatements (Nos. 62-70). Certain study design characteristics apply to the specific Workstatements under this RFP. Most of the requirements for the Workstatement study design will be detailed in the specific workstatement. Each workstatement will have a specific period of performance. The workstatements are: Workstatement #62- Evaluation of Chemopreventive Agents by Whole Body Real Time Imaging Using Orthotopic Transplantation of "Phenotypically Normal" Tumor-Derived Human Cells; Workstatement #63 - Effects of Chemopreventive Agents and "Folate-deficient Western Diet" on Colon Cancer in Compound Mutant Mice; Workstatement #64 - Effects of Chemopreventive Agents and Folate Deficient Diet on Mouse Models of Acute Promyelocytic Leukemia: Intermediate Endpoints of Disease Progression; Workstatement #65 - Intermediate Biomarker Discovery from Altered Gene Expression in Animal Tumors: Modulation Of Gene Expression By Known Chemopreventive Agents; Workstatement #66 - Comparative Genomic Hybridization Analysis of Multiple Mouse Animals Models of Cancer and Determination of the Effects of Chemopreventive Agents; Workstatement #67 - Induction of Genes by Retinoids and Soy-Related Products: Effects of Various Agents, Dose-Response Relationships, and Expression of Genes in Multiple Tissues; Workstatement #68 - Examination of Potential Biomarkers of Chemopreventive Effects in Colon Lesions And Normal Mucosa and in Lung Lesions And Normal Parenchyma; Workstatement #69 - Examination Of Biomarker Modulation Following Treatment With Potential Chemopreventive Agents In A UV Induced Model Of Skin Tumorigenesis; Workstatement #70 - RNA Expression Profiles of COX-2 Inhibitors in the Colon of Mock-Treated and Carcinogen-Treated Mice.
