The experimental protocols in animals should parallel potential clinical chemoprevention protocols for breast cancer in humans, 2) identification of potential targets found both in hormonally non-responsive animal models of breast cancer and in ER negative breast cancer in humans and 3) determination of the efficacy of potential chemopreventive agents. Modulatable surrogate biomarkers are broadly defined and might include gene or protein expression, specific DNA mutations or chromosomal alterations or characteristics associated with imaging (e.g. breast density, nuclear morphometry, etc.) which can be quantitatively altered by an effective chemopreventive agent. Modulatable surrogate biomarkers could be examined in lesions (preinvasive lesions, invasive lesions), in at risk epithelium or in serum. One should be able to demonstrate a strong correlation between alteration of the biomarker and the effects of the chemopreventive agent on tumor incidence and multiplicity in the animal model. RESEARCH OBJECTIVES Background Preclinical studies using animal models have been critically important for identifying a number of chemical agents which are now being applied in the prevention of cancer (e.g., tamoxifen , raloxifene, retinoids, COX-2 inhibitors). Animal models aimed at developing new, specific and potentially potent agents for prevention of ER negative breast cancer as well as potentially offering modulatable biomarkers should accelerate and drive forward the clinical research on ER negative breast cancer. These developments should help to diminish the risk of ER negative breast cancer and, in conjunction with agents which are effective against ER positive breast cancer (tamoxifen, raloxifene, aromatase inhibitors) , offer the possibility of regimens which will profoundly decrease the overall risk of breast cancer. The American Cancer Society estimates that in this year 193,000 new cases of breast cancer will be diagnosed and that roughly 40,000 women will die of this disease. It is estimated that roughly 30% of breast cancers are ER negative and that they represent 12-15,000 of the breast cancer related deaths each year. Short term pilot (Phase II) clinical studies in women at risk of developing ER negative breast cancer represent an efficient way of demonstrating potential efficacy of preventive agents. These studies depend heavily on the development of potential agents and cancer-related surrogate endpoints employing animal models. Such endpoints might include: levels of expression of specific genes or proteins, incidence or levels of specific genetic alterations (LOH, microsatellite alterations, FISH, mutations in suppressor/oncogenes, base methylation in certain genes), and or parameters related to image analysis, (e.g., nuclear morphometry , breast density, etc.). Such endpoints could be determined in lesions, in epithelial cells at high risk of developing cancer or in serum. These surrogate markers can be validated in animal studies where experiments can be followed till the production of invasive tumors. Surrogate endpoints that have already undergone some studies in animal models for breast cancer include expression of various genes, proliferation, apoptosis, and nuclear imaging. The incorporation of newer imaging technology into small animal cancer prevention assays to validate their future use in clinical trials protocols is also encouraged. However it is clear that a larger effort is needed to validate surrogate endpoint biomarkers in preclinical models employing intermediate endpoints similar to those proposed clinically for women at high risk of ER negative tumors. Once validated in animal models with a cancer endpoint, these biomarkers could then be rapidly translated into the clinical trials effort. In developing these endpoint biomarkers, the use of classes of agents which appear to be promising for ER negative breast cancer (e.g. COX-2 inhibitors, EGFr inhibitors, RXR agonists , farnesyltransferase inhibitors, etc.) might be prime candidates. Biomarkers developed for these drugs could be immediately translated to clinical trials. In contrast markers developed for totally new agents will require significant toxicologic and pharmacologic testing of those new agents prior to their use in clinical trials. Further studies with several potential classes of agents warrant further evaluation in relevant preclinical animal models before they can be nominated for preventive interventions in the population of women at risk for ER negative disease. For example, members of the non-steroidal anti-inflammatory drug family (NSAIDs) have shown some efficacy in hormonally responsive models of breast cancer and their primary target COX-2 is expressed in ER negative tumors as well. Therefore, further investigations of this class of agents in ER negative models appears appropriate. Based on preclinical animal studies and limited human studies, other potential agents to consider, include inhibitors of Neu and EGFr, rexenoids, farnesyl transferase inhibitors , etc. While these are examples, additional agents based on specific targeting to ER negative tumors are encouraged for testing in these applications. One might hope that additional targets might be defined by examining genes or proteins whose expression is altered in ER negative breast cancer. Thus EGFr and Neu have been identified as potential targets. However, the continued cataloging of gene and protein expression changes by RNA or proteomic approaches is likely to result in many additional targets. Combination prevention trials targeting specific biochemical pathways may also have great potential for leading to more effective preventive strategies based on multiple mechanistic approaches. Thus the combination of an antiestrogen/estrogen plus a rexenoid appears to have synergistic effects in ER positive breast cancer models in animals. Objectives and Scope: The development of animal model protocols that can facilitate the discovery and development of agents to prevent or diminish the risk of ER negative breast cancer in women represents an extraordinary opportunity to reduce breast cancer incidence, morbidity, and mortality. The purpose of this initiative is to invite investigator-initiated grant applications developing and evaluating chemopreventive strategies preclinically which could be rapidly translated to clinical studies and are applicable to women at high risk for development of ER negative breast cancer. The range of activities supported by this RFA would include preclinical studies to: 1) develop modulatable endpoint biomarkers in animal models of hormonally non responsive breast cancer employing effective preventive agents. Such biomarkers might include: gene or protein expression, or specific molecular changes, DNA mutations, image analysis etc. in specific preclinical models in which relevant cancer incidence and multiplicity are decreased by known effective agents. Interventions and determinations of endpoints that parallel potential clinical protocols are of particular use. Thus clinical protocols are likely to examine preinvasive lesions, at risk epithelia or sera in addition to more advanced lesions for modulation of potential endpoints. However a portion of any protocol would be to carry animals to an invasive tumor endpoint to determine the correlation of marker modulation and the final tumor endpoint. 2) test and prioritize agents using preclinical animal models for ER negative breast cancer. It would be expected that >40% of the animals would develop hormonally non responsive mammary tumors in any model that is proposed. In addition the model should develop preinvasive and invasive lesions that are histologically similar to that observed in human breast cancer. The purpose of this RFA is not primarily to support development of totally new animal models for ER negative breast cancer. However, a grant which includes as a component limited alteration or optimization or prevention testing in a previously developed model is not precluded. If one employs a transgenic animal model one must determine whether a given chemopreventive agent affects expression of the promoter. 3) Further characterize by genomic, proteomic or imaging techniques changes associated with hormonally non responsive breast cancer in multiple animal models as well as correlating with those seen in lesions or serum of humans with ER negative breast cancer or individuals at high risk of developing, ER negative breast cancer. In order to facilitate these comparative studies NCI will supply grantees funded via this RFA with a limited number of animal tumors, normal tissue and serum samples from 3 different hormonally non responsive tumor models. The specific models may be from rats or mice and will depend on availability. NCI will not supply rodents for the primary chemopreventive studies. Applicants are especially encouraged to apply chemopreventive agents directed against certain of the recently identified molecular targets found in ER negative breast cancer in humans (e.g. Neu, EGFr, COX-2) . Although it is anticipated that any model would have been characterized for the presence of histopathologic lesions it would be useful to do some early characterization of any models for gene expression patterns and expression of targets that are similar to that observed in humans. Approaches comparing any animal results to known results in humans. For example, the published published results of Perou, et al (Nature 406, 747-752 or results from the CGAP web site ( etc., can be employed. Based on these initial characterizations the applicant should identify potential markers, e.g., genes or gene products which are over expressed or under expressed in hormonally non responsive mammary lesions in their model. The investigators funded under this RFA will be encouraged to collaborate with scientists involved in the Mouse Models for Human Cancer Consortia (MMHCC) and take advantage of animal models developed in the MMHCC. Transgenic animal models for mammary cancer are already under development and might be used with the application of drug development. Similarly newly developed imaging techniques that as are being evaluated as part of the MMHCC activities could be incorporated. The total project period for applications submitted in response to the present RFA may not exceed 5 years. Because the nature and scope of the research proposed in response to this RFA may vary, it is anticipated that the duration and sizes of awards will vary also. Therefore applications will be accepted for R01, R21/R33, and competitive supplements to existing awards in this area. MECHANISM OF SUPPORT This RFA will use the National Institutes of Health (NIH) research project grant (R01) award mechanism. As an applicant, you will be solely responsible for planning, directing, and executing the proposed project. This RFA is a one-time solicitation. Future unsolicited, competing-continuation applications based on this project will compete with all investigator- initiated applications and will be reviewed according to the customary peer review procedures. The anticipated award date is April 2003. This RFA uses just-in-time concepts. It also uses the modular and non-modular budgeting formats. (see Specifically, if you are submitting an application with direct costs in each year of $250,000 or less, use the modular format. Otherwise, follow the instructions for non- modular research grant applications. FUNDS AVAILABLE The NCI intends to commit approximately $3.0 million in FY 2003 to fund 7 to 10 new and/or competitive continuation grants in response to this RFA. An applicant may request a project period of up to 5 years and a budget for direct costs of up to $300,000 per year. Facility and Administrative costs on consortium arrangements are not included in direct cost requests greater than $250,000.
