Goal 3: Advance Translational Research

Genome Profiling

There is a need to facilitate the integration of genomic and epigenomic profiling into drug discovery efforts by using genomic methods to sequence and analyze blood disease subtypes.

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

Details on the impact of addressing this CQ or CC :

Despite the important information that has been generated from sequencing studies in various blood disorders, for many hematologic disease subtypes, the limited scope of sequencing and the insufficient number of cases sequenced has prevented researchers from gaining truly useful insights. Whole-genome sequencing of large numbers of samples, with an emphasis on poorly studied and rare entities, is required to fully define the landscape of genetic changes underlying the development of blood diseases. Further, genetic and epigenetic alterations that drive hematologic diseases and the extent to which normal cells are distinct from malignant cells needs to be more broadly elucidated since many blood diseases, including hematopoietic cancers, disturb epigenetic regulators. The knowledge gained from understanding these processes and integrating genomic and epigenomic profiles could provide additional precision medicine opportunities and guide drug discovery efforts.

RFA on EC-cardiomyocyte interactions in the mechanisms and treatments of cardiovascular diseases

Often under recognized, the cardiac endothelial cells are highly abundant in the heart, and may have important roles in modulating cardiac function, besides simply serving as structural component of blood vessels. Evidences of ours and others have indicated an emerging role of cardiac endothelial cells signaling to cardiomyocytes to mediate important pathophysiological responses. Nonetheless, detailed mechanisms of ...more »

Successfully addressing this question would no double reveal novel mechanisms and ways of monitoring treatment responses of cardiovascular disease, ultimately leading to novel drug targets, valuable biomarkers and extended new directions of basic research as well.

Feasibility and challenges of addressing this CQ or CC :

Tools of studying these cells are mostly available. Both adult cardiomyocytes and endothelial cells from the heart can be isolated and cultured, although cardiomyotyes need to used within 24 hrs and cannot be passaged. However successful preparation of these cells from WT and transgenic animals would permit co-culture experiments and mechanistic studies. These cells can also be studied using in-situ techniques either detecting molecular changes/events or dynamic interactions. Potential challenges would side in selective targeting of these cells, for example, either ECs or cardiomyocytes, once a potential therapeutic is in the testing. Nonetheless, PECAM-ab conjugated techniques have been employed to specifically deliver proteins to endothelial cells, so I am confident most of the challenges can be worked out, particularly within a RFA awardees group with frequent exchanges of ideas.

Genome Editing and Gene Therapy

There is a critical need for the establishment of strategies that will determine the efficacy, safety, and toxicity of genome editing techniques specifically in hematologic diseases.

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

Details on the impact of addressing this CQ or CC :

Inherited monogenic hematologic diseases such as hemophilia, beta-thalassemia and sickle cell disease are prime targets for future application of genome editing technology. However, studies are still needed to advance our understanding of the biology of genome editing as well as determine which other disorders are amenable to genome editing correction. Emphasis on preclinical research that focuses on determining the accuracy, safety and efficiency of this technology in order to help minimize off-target mutations and reduce toxicity, is essential for effective translation of this technology into the clinic. Once preclinical efficacy is established, support will be needed for clinical vector production, toxicity testing of the vectors/reagents used, and the performance of clinical trials. The gene correction strategies developed for inherited disorders will also be attractive for other hematologic diseases, and autoimmune disorders like lupus, rheumatoid arthritis, and type I diabetes). There is also a critical need for supporting preclinical validation studies, scale-up and GMP cell manufacturing, all of which could be shared infrastructures across multiple diseases in the NHLBI portfolio.

Goal 2: Reduce Human Disease

Non-Adherence of Patients with Chronic Respiratory Diseases

There are various reasons responsible for patients’ non-adherence. One of them is insufficient or lack of education about medications and equipment required for their treatment.

Submitted by (@vlady.rozenbaum)

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

Details on the impact of addressing this CQ or CC :

There is a critical need to develop uniform guidelines and handouts addressing the confusion over the proper use of medications (particularly inhalers) and equipment (i.e. oxygen). Improper use leads to diminished or no benefit, frustration, and, ultimately, even to a patient's decision to stop the treatment.

Feasibility and challenges of addressing this CQ or CC :

This is an issue that has been universally acknowledged for a number of years. With the help of patient focus groups, convened at the NHLBI, national pulmonological conferences, or at local venues around the country, appropriate materials can be created to benefit patients and reduce a huge burden on nation's economy due to decreased productivity and increase in hospital admissions.

Stem Cell Biology

There is a need to develop an artificial and functional hematopoietic stem cell (HSC) niche that allows for the expansion of repopulating HSCs.

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

Details on the impact of addressing this CQ or CC :

Methods to expand hematopoietic stem cells have continued to be examined extensively because stem cell numbers in the graft are important for clinical outcomes following transplantation. These numbers are particularly relevant in umbilical cord blood (UCB) transplantation, where low numbers of stem cells are directly related to delayed hematopoietic and immune reconstitution. Improved HSC expansion strategies may significantly impact transplantation outcome, enabling broader applications beyond UCB transplantation. Furthermore, these strategies are also needed to realize the full therapeutic potential of genome editing technologies to correct hematopoietic stem cells derived from patients with hematologic disorders. Since efforts to expand HSCs in cytokine-supported liquid cultures have been largely unsuccessful, efficient expansion will require an appropriate context that is provided by the hematopoietic stem cell niche. Future studies must also evaluate how niche signals regulate stem cell function to optimize cell expansion, and proper humanized mouse models must be developed to help predict stem cell function and regulation by the niche.

Stem Cell Biology

There is a need to develop “designer platelets” and “designer red cells,” as well as facilitate large-scale production of these products for therapeutic and diagnostic use.

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 reprogramming of adult stem cells has resulted in the generation of induced pluripotent stem cells (iPSCs) that can develop into any tissue of the body. These iPSCs ultimately may be used as a transplantable source of stem cells for a variety of hematologic diseases. Although this technology has enabled the generation of patient-specific or disease-specific stem cells that are also amenable to genetic manipulation, the major scientific hurdle has been the ability to create clinically meaningful functional blood products, including transplantable HSCs from differentiating iPSCs. The production of clinically functional blood products -- i.e. red blood cells derived from autologous iPSCs --could replace allogeneic products in highly immunized patients and the generation of megakaryocytes for patient-specific platelet production from iPSCs could drive significant progress in this area. Furthermore, disease-specific iPSCs could serve as targets for both drug development and drug screening in patients with rare hematologic disorders. In addition, support for scale-up and GMP processes, which are difficult to fund via the R01 mechanism will require specific grant opportunities tailored to infrastructure and process development.

Immunologic Treatment of Hematologic Malignancies

How can the use of CAR T-cell and checkpoint blockade strategies be optimized in order to cure hematologic diseases?

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

Details on the impact of addressing this CQ or CC :

As the body of evidence continues to grow on the potential applications for advanced immunotherapies, next-generation research must focus on addressing the possible curative effects that checkpoint blockades or adoptive CAR T-cell strategies can have for blood diseases including hematologic cancers. This will require specific research programs to fully understand the optimal role for these therapies within the continuum of care. To optimize these strategies for treatment of hematologic diseases, studies are needed to decipher specific hematologic diseases and circumstances under which these checkpoint blockers and CAR T-cell therapies may be employed as frontline approaches. Furthermore, while the optimal approach for these therapies is unclear, advanced studies are needed to elucidate the potential benefit in combining these promising approaches and whether patients can be better identified a priori for these therapies.
