Goal 2: Reduce Human Disease

DEVELOPMENT OF A PERSONALIZED APPROACH TO SLEEP AND CIRCADIAN DISORDERS

There is developing evidence of major individual differences in pathways to different common sleep disorders such as obstructive sleep apnea. Moreover, there is evidence of different clinical presentations of disease and different outcomes. For example, some subjects with obstructive sleep apnea who get excessive sleepiness while others do not. The latter are still at risk for other consequences of the disorder such... more »

Details on the impact of addressing this CQ or CC

There is a strong rationale for application of a personalized approach to sleep disorders. This requires approaching this question using multiple domains as in other areas of medicine—clinical features, physiological factors, application of the –omic approaches, genetics. The impact of this will be several:

a. A new way to classify sleep disorders.
b. Identification of subgroups of patients with apparently the same disorder who will have different outcomes of therapy.
c. Identification of subgroups of patients who will have different approaches to diagnosis.
d. Identification of subgroups of patients with apparently the same disorder who will have different therapeutic approaches.

Feasibility and challenges of addressing this CQ or CC

These sleep and circadian disorders are extremely common. There is a risk infrastructure for this type of research based on the large number of accredited sleep centers in the United States that could be used for subject recruitment and who can adopt similar techniques. There is also a rich set of data obtained from sleep studies that could be used to identify new patterns that reflect different subgroups of subjects. These studies need to be based on clinical populations of patients who present with the different disorders rather than on population-based cohorts.

Goal 2: Reduce Human Disease

The role of Extracorporeal Photopheresis (ECP) in the prophylaxis and treatment of acute & chronic Graft Versus Host Disease

In Acute Graft Versus Host Disease (aGVHD), we would like to examine whether early and intensified delivery of ECP as part of standard prophylaxis will decrease overall corticosteroid exposure while preserving expected relapse rates in patients undergoing unrelated donor hematopoietic stem cell transplantation (HSCT).
Chronic GVHD (cGVHD) is common after HSCT (30-50% recipients) and is a major contributor to late transplant-related... more »

Details on the impact of addressing this CQ or CC

Patients who develop aGVHD undergo toxic therapy with high-dose corticosteroids, often for long durations, resulting in high morbidity and treatment related mortality. Alternatively, T cell depletion of the donor graft to reduce GVHD is associated with high rates of infection and relapse of the disease that led to the HSCT. Targeting other pathways of GVHD pathogenesis may preserve the beneficial immune reconstitution and graft-versus-tumor (GVT) effects, while ameliorating the severity of GVHD. One such pathway involves regulatory T cells (T regs), which inhibit T cell alloreactivity, and are correlated with the incidence and severity of GVHD without loss of GVT. To date, there is no consensus on a standard second-line therapy for aGVHD, and current approaches focus mainly on intensification of immunosuppression. Addressing this compelling question will help to decrease overall corticosteroid exposure while preserving the expected relapse rates in patients undergoing unrelated donor HSCT.

Appropriate initial therapy for cGVHD involves high doses & prolonged use (yrs) of corticosteroids, while patients still develop irreversible sclerotic manifestations of disease. Early intervention prior to disease onset may help prevent cGVHD development or lessen its severity, requiring less corticosteroid exposure. Addressing the compelling question for cGVHD will help decrease exposure to drugs with associated morbidity, while preserving expected relapse rates in these patients.

Feasibility and challenges of addressing this CQ or CC

Feasibility:

  • GVHD has relatively high incidence after HSCT and at the same time there is a lack of consensus on standard second line therapy for the disease. Thus, there will be increased interest in developing and participation in those studies.

** ECP is generally well tolerated and complications are infrequent.

*** There is a great potential for multi-discipline collaboration approach in this patients’ population.

*** There is an opportunity to engage industry partners in the design and support for these studies.

**** There are numerous scientific opportunities for meritorious science as there have been limited systematic studies of ECP mechanisms of as well as standardization of apheresis protocols based on GVHD disease state.

 

 

Challenges:

  • Limited number of institutions providing ECP treatment.

** Cost of the procedures (although Centers for Medicare and Medicaid Services now covers ECP for cGVHD).

*** There is a very limited number of animal models available for apheresis research in general, and studies of the mechanism(s) of action of photopheresis have been very limited as well as difficult and expensive to perform. However understanding pathological mechanisms and its relationship to response to apheresis is critical for optimization and advancement of patient care.

****Lack of infra-structure for apheresis research.

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 Immunology

We now can create critical cell types like cardiomyocytes etc. from stem cells. Additionally, we are learning the rules of using these cells to rebuild tissues. A major gap in our knowledge relates to the immunobiology of these cells. Lessons from transplantation medicine are only partially applicable, because solid organs are more complex and likely more immunogenic than defined cell populations.

Details on the impact of addressing this CQ or CC

We now can generate large quantities of critical cell types whose deficiencies underlie many chronic diseases like heart failure. This breakthrough brings us to the next-level impediment: the immune system. While induced pluripotent stem cells have the potential to obviate rejection, in practical terms this is cost-prohibitive: It will cost huge amounts of money to produce and qualify a single patient's cell dose. Moreover, human cardiomyocytes are potent when given to infarcted hearts in the acute or sub-acute phase of infarction, but they have no benefit with chronic heart failure. The 6 months required to produce iPSC-cardiomyocytes precludes their autologous use for myocardial infarction.

We need an off the shelf cell therapy product for myocardial infarction that can be mass produced and qualified for large numbers of patients. This means an allogeneic product is necessary. Identifying the immune response to cardiomyocytes or other cell products will teach us how to precisely immunosuppress the patient, thereby minimizing complications, or alternatively, how to engineer the cells so as to avoid immunogenicity in the first place.

Lessons from the study of cardiomyocyte transplantation could extend to dopamine neurons, pancreatic beta-cells, retinal cells, myelinating cells and many other areas that cause common chronic disease.

Feasibility and challenges of addressing this CQ or CC

We know a great deal of transplant immunology from hematopoietic stem cell transplantation (graft versus host) and from solid organ transplantation (host versus graft). There are good mouse and large animal (including non-human primate) models of stem cell differentiation and organ transplantation. This offers low hanging fruit where, in perhaps 5 years, we could discern the critical similarities and differences between transplanting stem cell derivatives and organ or marrow transplantation. These studies will inform clinical trials of allogeneic human stem cell derivatives that will be underway by then.

Success in this area will require bringing together researchers interested in stem cell biology and transplant immunology. A properly resourced RFA from NIH could be just the thing needed to promote this interaction.

What is the optimal treatment goal for hypertension?

In adults without diastolic hypertension (DBP ≥ 90 mm Hg), what is the best way to determine at what systolic blood pressure should treatment be initiated?

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 failure to resolve the debate about what is the appropriate goal for treatment of systolic hypertension could adversely effect the progress we have made in reducing the level of systolic blood pressure among the one third of adults with hypertension. At the heart of this debate is what is the optimal balance between lowering systolic blood pressure versus causing adverse consequences in those who are being treated for hypertension.

Feasibility and challenges of addressing this CQ or CC

Because the existence of large clinical research networks with electronic medical records and use of generic drugs, all mean that a large pragmatic trial is definitely feasible.
Despite fifty years of clinical trial research and forty years of national guideline activity, important clinical questions remain under intense scientific debate. The importance of these questions is underlined by the scientific consensus that hypertension is the most important cardiovascular risk factor globally, in fact, more important than even tobacco use. Further hypertension research could be important because of the role of hypertension not only in CVD, but also in chronic kidney disease, stroke, and possibly in dementia and age related cognitive decline.

Influence of the Gut Microbiome on Pulmonary Immunity in HIV-Infected Individuals

It has become increasingly clear that gut microbiota have a tremendous impact on human health and disease. While it is well known that commensal gut bacteria are crucial in maintaining immune homeostasis in the intestine, there is also evidence of indirect effects on the lung. Multiple studies have shown that alterations in gut microbiota can lead to severe defects in pulmonary immune responses and reduced ability to... more »

Details on the impact of addressing this CQ or CC

HIV-infected individuals are at significant risk of developing and dying from infectious and non-infectious pulmonary complications. Alteration of gut microbiota have been shown to have dramatic effects on pulmonary immunity and severity of lung infections. For instance, multiple studies have indicated that probiotic treatment with certain Lactobacillus and Bifidobacterium strains results in reduced incidence and severity of upper respiratory tract infections in children. Similarly, a recent study showed that treatment with the minimally absorbed antibiotic neomycin was associated with alterations in gut microbiota composition and concomitant reduced pulmonary immunity and the inability to control Influenza infection in mice. It was recently described that HIV infection is associated with a dramatic alteration in gut microbiota and that these changes persist with antiretroviral therapy (ART). Thus, it is important to understand how these alterations may effect lung immunity, since the majority of HIV-infected individuals develop pulmonary infections. Furthermore, gut microbiota contribute to development of non-infectious complications such as atherosclerosis, metabolic disease, obesity and diabetes. It is thus highly plausible that the gut microbiota may also play a role in the development of non-infectious complications of the lung such as Chronic Obstructive Pulmonary Disease and Pulmonary Hypertension, the rates of which are elevated in HIV-infected individuals.

Feasibility and challenges of addressing this CQ or CC

A better understanding of how alterations in gut microbiota associated with HIV infection affects pulmonary infectious and noninfectious complication could lead to therapies to protect this “at risk” group. Furthermore, manipulation of the gut microbiota in HIV-infected individuals using pro- and/or pre-biotics, antibiotics or diet modification to a composition that is associated with increased pulmonary immunity, reduced infections and lung complications are all low risk therapeutic strategies that could substantially improve lung heath in these individuals.

Decisions on whether or not to place a patient with atrial fibrillation on chronic anticoagulation or on statin therapy are often based on guidelines and cardiovascular risk calculators.

Patients with a higher risk of stroke are more likely to receive anticoagulation and patients with a higher risk of a myocardial infarction are more likely to receive statin therapy.

However, these cardiovascular risk calculators do not really take into account the potential side effects and impact on the lifestyle of the patients.

Physicians will stop anticoagulation in a patient with atrial fibrillation if the patient has suffered a life-threatening bleed but there are no specific evidence-based guidelines as to how one should proceed if the bleeding is minor.

it is easy to compute the cardiovascular risk and overall mortality benefit of placing a patient on statins but how does one factor in the impact that statins have on the quality of life of an individual?

Developing novel evidence-based approaches to individualize therapies that factor in cardiovascular benefits as well as potential side effects and diminished quality of life could have a major impact on appropriately using treatments and reduce the arbitrariness of some medical decisions.

As detailed in the attached review (Kroncke et al. Biochemistry 2015, 54, 2551−2559) the successful practice of personalized medicine will in many cases require a molecular-level understanding of the nature of the defects that are caused by disease-predisposing genetic variations. As widespread personal genome sequencing becomes routine, numerous genetic variations (many millions) of uncertain significance will be discovered. Using both experimental and computational tools associated with the fields of biochemistry, biophysics, and structural biology it is in many cases possible to ascertain whether a newly-discovered gene variation adversely impacts a critical protein or RNA function and, if so, how. Among various clinical applications this information can be used (i) to project whether a patient not currently showing symptoms for a particular disease is likely to present with that disease in the future (sometimes enabling prophylactic therapy), (ii) to help establish the molecular etiology of a disease currently afflicting the patient, and (iii) to guide the therapeutic strategy pursued for that patient.

Feasibility and challenges of addressing this CQ or CC

My lab is already participating in a project (RO1 HL122010) with two other labs (those of Drs. Jens Meiler--Vanderbilt and Alfred George--Northwestern) to develop personalized biochemical and biophysical approaches for application to genetic variations impacting the KCNQ1 gene, potentially predisposing patients to long QT syndrome, a cardiac arrhythmia. However, our project deals with one gene and one disorder only. There clearly is a need for improved and expanded communication and collaboration between those practicing personalized/precision medicine and those who are well-equipped to provide medically actionable molecular insight using the approaches of personalized biochemistry, biophysics, and structural biology.
