Goal 2: Reduce Human Disease

Interactions between anticoagulant therapy and antiretroviral drugs

Cardiovascular pathology has become a major problem in the management of the HIV-infected patient during the ART era. A large number of HIV patients will receive anticoagulants drugs for secondary prevention of cardiovascular disease. It is therefore critical to understand the interactions between antiretroviral therapy and anticoagulant therapy to safely treat HIV patients.

Details on the impact of addressing this CQ or CC :

With over 50% of HIV-infected patients in the US anticipated to be > 50 years of age by 2015, the overall risk of CVD will be significantly higher and could become the main challenge for the management of chronic HIV infection. A large number of HIV-infected patients with CVD will therefore need treatment for primary and secondary prevention of atherothrombotic events. The secondary prevention of CVD almost invariably includes prescription of one or multiple anticoagulants drugs. It is therefore conceivable that anticoagulant therapies will be frequently associated with ART for the management of HIV patients, which already developed CVD. The interactions between these therapies are not well studied and are critical for the management of the HIV-infected patients.

Feasibility and challenges of addressing this CQ or CC :

Feasibility: 1) retrospective studies on a large number of HIV patients that had cardiovascular events and were treated with antiretroviral drugs; 2) prospective studies comparing different antiretroviral regimens associated with the most current anticoagulant therapy recommended for secondary prevention of CV disease; 3) use of animal models of AIDS for testing new anticoagulants and the interaction with the antiretroviral drugs.

Animal Models for COPD -- Core Facilities

COPD is a major health problem with more than 140,000 deaths per year and yet there is a relative paucity of treatments that might modify the course of this disease. In part, this is due to the poor efficiency of animal models that require months of exposure to cigarette smoke. Moreover, there are no well validated small animal models of chronic mucus hypersecretion. Funding of core facilities that could both provide ...more »

Goal 3: Advance Translational Research

Develop relevant large animal models for various disease conditions

What is the possibility of investing funds primarily in clinically-relevant models where the findings could be translated in to human diseases?

Details on the impact of addressing this CQ or CC :

Strong emphasis on the use of a clinically-relevant large animal model would hopefully be more productive in developing better therapeutic approaches and management of patients.

Feasibility and challenges of addressing this CQ or CC :

In view of the lack of facility at many institutions and the cost involved, and the rules and regulations by the USDA and other regularity bodies, special emphasis will be required to build the animal facility at an institution. Where will the funds come from? Similar to many other core facilities set up by the NIH at various institutions, what is the possibility of developing specialized centers for testing a new idea in a clinically-relevant large animal facility?

Goal 3: Advance Translational Research

Funding for synthesis and screening of potentially therapeutic molecules

Currently, there are limited, if none, funding resources to synthesize and screen potentially therapeutic molecules, based on supportive findings in cells, biopsy tissues from the patients with the disease in question, and the preliminary data to support the development of a series of compounds to screen them for their pharmacokinetics, pharmacodynamics, toxicity and use in clinically-relevant large animal models.

Is this idea a Compelling Question (CQ) or Critical Challenge (CC)? : Compelling Question (CQ)

Details on the impact of addressing this CQ or CC :

Although NHLBI-NIH and other institutes emphasize on mechanistic approach, to my knowledge, translation of the findings into the development of novel molecules is rarely pursued in a multi-disciplinary manner. this could have a significant impact on developing better therapeutic and/or management approaches of various diseases.

Feasibility and challenges of addressing this CQ or CC :

In the past, NIH has come up with many RFAs related to this issue. However, one of the major challenges has been the screening of the compounds in a model relevant to human disease. For example, in cardiovascular diseases, about 99% studies are done in mouse models. From genetic studies point of view, this is acceptable, even though now large animals are used for knock-in and knock out gene studies. However, from the screening point of view, an emphasis must be placed on clinically-relevant model, for example, swine, where most of the findings, if not all, could translated to human disease.

Goal 3: Advance Translational Research

Developing animal models of lung transplantation.

Lung transplantation as a cure for terminal lung disease has seen little improvement in outcomes for more than 20 years. The field remains highly challenging, in part, because of an absence of robust animal models which are technically- feasible and reproducible across centers. Further, models have limited relevance to clinical (chronic) airway remodeling, the leading problem in pulmonary allografts. In the absence of ...more »

Details on the impact of addressing this CQ or CC :

The critical challenge is to address the leading problems facing lung transplant patients through the creative application of multiple technological platforms employing all available pre-clinical models by multiple NIH investigators. With greater focus on the deeper development of existent models, the delineation of their strengths and limitations and importantly, cooperation between Academic Centers, efforts can be optimized to improve outcomes for a condition that has enjoyed little benefit from basic research.

Feasibility and challenges of addressing this CQ or CC :

The siloed nature of much clinical and experimental lung transplantation research limits progress and broader initiatives. With specific respect to developing animal models of lung transplantation, the general lack of consensus about the suitability of the techniques employed at different institutions stifles progress. A strategic vision, guided by leaders across the field, highlighting benefits and limitations of current animal models can be coupled with a consensus statement about the most pressing issues in lung transplantation worthy of increased investigation.

New analysis methods for research using animal models

The idea that 'animal models can faithfully predict the outcomes in human clinical trials of new medicines and treatments' is highly compelling. However, due to differences (biological and non-biological) between humans and animals this goal can likely not be achieved. Not only are animals genetically different from humans, everything else is different too. Even if living quarters are shared (e.g. house pet animals), ...more »

Details on the impact of addressing this CQ or CC :

Because of the differences between humans and animals, a different paradigm of expectations and analysis methodology needs to be developed. Animal models (natural and man-made) have been superbly informative for developing means to improving human health. The key to 'successful animal models' is the interpretation of the data - and the careful design of the animal studies to capture one of the essential molecular, environmental, behavioral problems that cause the human disease and to model the essential problem in the animals.

Feasibility and challenges of addressing this CQ or CC :

At the moment, the specific design of animal models and the interpretation of the data is in the hands of individual scientists. Specific guidelines could be developed for every aspect of animal experimentation and this would help to optimize the output with respect to understanding the next steps: e.g. is this data useful in basic science, in translational science, which questions need to be answered using the analysis of human individuals ? The availability of specific methods will allow us to better move between bedside to bench and back.
