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.

Epigenetics and Genomics

There is a need to investigate hemoglobin biosynthesis in order to develop novel approaches to treat sickle cell disease, thalassemia, and other anemias.

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

Details on the impact of addressing this CQ or CC :

Studies on epigenetic mechanisms have extraordinary promise for the development of transformative therapeutic approaches for non-malignant hematologic disorders, however, limited progress has been made in advancing therapies to counteract the often crippling complications of these conditions. In the case of sickle cell disease, an ensemble of proteins has been implicated in mediating the epigenetic repression of gamma-globin expression, raising the possibility that antagonizing the actions of these proteins to increase gamma-globin expression may be a useful treatment strategy. However, in certain cases, some of these proteins are deemed “undruggable,” based on their structural attributes. There is a critical need to identify druggable components of the multi-step epigenetic mechanisms as well as develop better models and assays that will more effectively identify modulators of “undruggable” proteins. Given the rich proteome and improved technologies available today, studies of proteomics, metabolomics, and regulatory RNAs are likely to reveal promising translational avenues. In addition, approaches to modifying the expression of the components of this pathway are underway using developing gene therapy strategies, such as viral vectors and/or gene editing can quickly advance therapy in sickle cell disease and β-thalassmia.

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.

Genome Profiling

What structural changes need to be implemented in the health-care community in order to support the use of genomic information in clinical trials and drug development for 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 :

In various blood disorders, including hematologic malignancies, there are both inherited and somatic genetic alterations that contribute to predisposition, transformation, disease progression, responsiveness to therapy, and treatment complications. The presence of such genetic alterations underscore the need for the identification of rare but traceable mutations as well as the integration of such genomic information into clinical trials. By implementing a few structural changes in the healthcare sector, a clinical trial infrastructure can be established that accounts for proper application of sequencing technology. Some examples include the creation of genome diagnostic networks that address accrual of sufficient patients, procurement of suitable tumor/non-tumor material for sequencing, as well as pharmacodynamic and correlative biology studies in hematologic diseases.

Venous Thromboembolism

There is a great need for the development and evaluation of biomarkers for the study of venous thromboembolism (VTE) pathophysiology and risk assessment.

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

Details on the impact of addressing this CQ or CC :

Recent efforts to evaluate biomarkers for VTE occurrence and recurrence have led to the identification of multiple potential candidates, including P-selectin, E-selectin, D-dimer, various microparticles, and various inflammatory cytokines. However, no specific biomarker has yet emerged for routine clinical use for individual VTE risk stratification and personal targeted therapeutics. The development of improved animal models will advance the study of VTE pathophysiology, allowing for more accurate evaluation of emerging biomarkers and initial assessments of potential advanced therapeutic interventions. Also, the identification and prioritization of novel VTE biomarkers will be needed to help improve our understanding of the molecular mechanisms underlying VTE, so as to shepherd the development of novel mechanisms of therapy beyond anticoagulation.

Predictors of Sickle Cell Disease Severity

Can better predictors of disease severity such as specific biomarkers and/or genetic polymorphisms be identified so as to help understand the course and progression of sickle cell disease in various patients?

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

Details on the impact of addressing this CQ or CC :

The high clinical variability in sickle cell disease (SCD) and the lack of sufficient data to help understand and or predict the course of an individual’s disease warrants the identification of better predictors of disease severity. The identification of predictors of disease severity, such as biomarkers, will be vital in the management and treatment of SCD, especially since more recently several plasma biomarkers and certain genetic polymorphisms have been proposed to influence specific clinical outcomes, including stroke, sickle cell nephropathy, and survival. Furthermore, studies of biomarkers or genetic markers in the context of clinical drug trials may be helpful in predicting response rates, thus allowing for more personalized therapeutic decisions.

Venous Thromboembolism

How can individual VTE risk-assessment scoring be combined with promising biomarker candidates in order to help predict risk in the general patient population and prevent unprovoked low-risk VTE cases?

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

Details on the impact of addressing this CQ or CC :

The VTE field is approaching a new era of therapy in which predictive measures at the primary care level will identify those patients most at risk for VTE. With the identification of predictive biomarkers for VTE occurrence, efforts will be necessary to develop point-of-care or in-home biomarker testing devices to improve risk-assessment scoring and identification, so that patients could then be treated before progression. It will also be critical to accelerate risk-scoring systems that are beginning to incorporate biomarker candidates into the algorithm for use in clinical trials. Studies that will focus on correlating risk-assessment scores and biomarker research findings will provide a more accurate risk prediction and diagnostic value.

Immunologic Treatment of Hematologic Malignancies

How can the effectiveness of existing curative therapies be improved for allogeneic hematopoietic stem cell transplantation?

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

Details on the impact of addressing this CQ or CC :

Much remains to be understood about immunotherapies in order to facilitate their broad use in the treatment of hematologic disorders. While studies to date have demonstrated significant potential applications, longer-term studies are necessary to further improve the profile of these therapies, including enhancing their overall efficacy while reducing associated toxicities. The efficacy of existing curative therapies can be enhanced by evaluating the mechanisms involved in producing cytokine release syndrome; a condition which has been observed in several patients receiving this therapy. Furthermore, a careful grading scheme to predict toxicity so as to guide the development of preventive and therapeutic strategies is also required. Target identification is another important issue to advance the field. While targeting CD19 appears to be promising, it results in loss of B-cell immunity and requires prolonged immunoglobulin replacement therapies and/or allo-transplantation and new immunologic targets need to be identified in both B cell and T cell malignancies as was as acute and chronic myeloid leukemias. Minimizing the off-tumor target-mediated toxicity of both CAR T-cell and checkpoint blockade therapies would help optimize their utility.

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.

How can proper infrastructure be designed to host sequencing data from hematologic diseases so as to enable its efficient interpretation and use in clinical care?

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

Details on the impact of addressing this CQ or CC :

Accurate and consistent analysis of genetic data is crucial for both basic research and clinical applications, however, the complexity of sequence mutations in several blood disorders as well as the immense amounts of raw data produced during the sequencing and analysis process, make accurate bioinformatics analysis a challenge. Furthermore, the lack of consistency in the analysis of the non-coding genome and variations in correlating this information with transcriptional and epigenetic data pose an additional challenge in obtaining a comprehensive portrait of various hematologic diseases. To overcome these challenges, content-rich portals that can offer cost-effective and regulated access to raw genomic data for interrogating and sharing sequencing results without compromising patient privacy must be designed. Also, the biologic and clinical relevance of genetic alterations found in these portals must be reliable and sufficiently comprehensive in order to foster proper interpretation.

Optimization of Existing Therapies for Sickle Cell Disease

How can the safety, dosing and benefits of existing therapies for sickle cell disease such as hydroxyurea, be optimized in order to increase its efficacy and improve patient adherence?

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

Details on the impact of addressing this CQ or CC :

Hydroxyurea is a widely available disease-modifying therapy for sickle cell disease (SCD), but its effectiveness is currently limited by inadequate utilization, and less than optimal response. Research is needed to improve adherence to this evidence-based therapy and emphasis needs to be placed on determining whether therapy with hydroxyurea can prevent or even reverse organ dysfunction. In addition, research identifying new adjunct therapies to blood transfusion and hydroxyurea, as well as disease-specific therapies for co-morbidities such as kidney disease, hypertension, obstructive lung disease, and pulmonary hypertension will be valuable in the management and treatment of SCD.
