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.

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.

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?

The Investigator's Catch-22: How Can NHLBI Help?

The Critical Challenge is to determine how NHLBI can continue to foster the translational research necessary to allow our researchers to further develop their NHLBI-funded basic science discoveries. Researchers can't readily get a "typical" grant to perform the preclinical and early clinical translational IND-enabling research, and also can't yet attract private sector support without having done the work to "de-risk"... more »

Details on the impact of addressing this CQ or CC

Ensuring that NHLBI-funded researchers have the means to further develop promising research discoveries will ensure that NHLBI continues to fulfill its Mission. Providing funding or resources to move basic science discoveries from the lab towards the clinic can expand the research environments, opportunities, and collaborations available to NHLBI investigators and lead to potential new therapies for heart, lung, and blood diseases.

Feasibility and challenges of addressing this CQ or CC

Just as research project itself can take years, if not decades, to accomplish, so too can a cultural shift in our extramural research community. While one may have a different understanding of what constitutes "translational" research depending upon his or her vantage point, in reality it is bi-directional (from bench to bedside and back to bench) and offers possibilities for a wide range of researchers. Engaging established basic scientists in translational research can open new opportunities to them, and younger researchers are likely more familiar and well-poised for new research paradigms and collaborative efforts such as those afforded by the translational development process.
Basic discovery science is appropriately the backbone of the NHLBI extramural research program. But, for any basic science discovery to have a meaningful impact on human health, it must be "translated from the bench to the bedside." These next steps in translation involve a tremendous amount of research that is not amenable to hypothesis-driven grant mechanisms like an R01 or P01. Without access to funding support for early-stage translational work, investigators can be stymied and NHLBI-funded basic science discoveries can languish.

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.

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

Enhancing Translational Returns With Better Animal Models and the Basic Science Needed to Support Such Efforts

Can we improve on the preclinical development of therapies through more informed choices on new animal models by linking basic science at the R01 level with national resource centers?

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

Details on the impact of addressing this CQ or CC

The development of effective therapies for heart, lung, and blood require the appropriate animal models for testing. Mouse models have been the mainstay and for the most part very effective. But for those diseases where mice fall short, humans have become the testing ground. With the massive push for translation at NIH, clinical trials often lack proof of efficacy in animal models or are wrongly based on biology in rodents that does not apply to humans. These clinical efforts that don’t effectively translate are exhausting resources to maintain a robust RO1 pipeline on basic research. Recognizing that we must push for translation and also keep basic research funded at a high level, NIH and NHBLI needs to get more creative in taping the best animal models for the disease.

Feasibility and challenges of addressing this CQ or CC

With new technologies rapidly expanding for transgenesis in embryos, picking the appropriate species for modeling a given disease is now becoming a reality. However, there are several barriers to growth in this area: 1) we often do not know organ physiology and stem cell biology well enough in non-rodent species, 2) the average researcher typically does not have the expertise to utilize non-rodent models in their research or to generate new genetic non-rodent models for study, 3) the costs of non-rodent disease models is high and must be strategically utilized. One potential solution is to maintain resource centers in particular key species that collaborate with basic scientists to both better understand non-rodent organ biology and work selectively to translate basic discovery into therapies. NHLBI recently had an RFA for this type of work that was discontinued. If a new RFA was designed that links funded research (and/or new research applications) through NHLBI to selected target mission diseases and the use of strategic resource centers with expertise in alternative non-rodent models, this might productively transition appropriate use of new models for the next generation of scientists. Such an RFA for example, could provide supplements to existing R01s for projects linked to resource centers and/or have specific R01 RFAs to enter into studies in new animal models or to create new models for a given purpose.
