DIRECTOR'S OVERVIEW

As the primary Federal agency for supporting medical research on diseases of the bones, joints, muscles, and skin, the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) touches the lives of nearly every American. Arthritis limits the activities of nearly 21 million adults in the United States each year; medical care and lost wages attributable to musculoskeletal conditions cost Americans an estimated $950 billion annually; and skin conditions such as eczema and psoriasis affect more than 12 percent of people worldwide¹. NIAMS is working to enhance health, lengthen life, and reduce illness and disability by supporting basic and translational research that will impact clinical practice, training the next generation of bone, joint, muscle, and skin scientists, and disseminating the findings and related health information from the studies it supports to all Americans. The activities described below are a subset of the Institute’s many efforts to advance public health.

Over the years, NIAMS-supported research teams have made significant progress in uncovering the causes of and improving the treatments for many disorders of the bones, joints, muscles, and skin. Basic discoveries that have recently been translated into clinical care include the Janus kinase protein (now the target of the new rheumatoid arthritis drug tofacitinib) and the relationship between neonatal-onset multisystem inflammatory disease (NOMID) and defects in the pathways targeted by the drug anakinra. (See Program Portrait: Translational Science in the Intramural Research Program, below.)

As researchers learn more about the cellular pathways that control development, growth, and repair, they are discovering many shared processes among the cells of the bones, joints, muscles, and skin. This knowledge is being leveraged to develop therapies that can repair or restore multiple tissues. For example, recent work has demonstrated that activation of a single protein in skin cells at the base of the fingernail is essential for nail regeneration, bone formation, and innervation of a new fingertip following amputation. While regrowth of complete human limbs is still not feasible, this finding provides an important piece of the tissue-regeneration puzzle and may one day lead to functional arms and legs for amputees.

Recent musculoskeletal research advances also have contributed to the recognition that bone, cartilage, connective tissue, and muscle communicate with one another through signaling molecules in health and disease. These complex interactions, which are still being explored, must be considered when developing and testing potential therapies for individual tissues or organ systems. Furthermore, as scientists learn how the circadian day/night cycle influences biologic activities, including muscle function, bone remodeling, and immune and inflammatory responses, they are recognizing that the timing of patients’ eating, sleeping, exercise, and medicine delivery may influence results of clinical studies.

Over the past decade, the genome-wide association approach to identify genetic regions related to disease risk has matured from an intriguing concept to a widely used scientific tool. Insights from numerous initial studies are being confirmed by replication of these studies in additional cohorts. For example, NIAMS-supported researchers recently identified 14 genes linked to juvenile idiopathic arthritis (JIA), the most common type of arthritis affecting children, bringing the number of confirmed JIA-linked genes to 17. This better understanding of JIA provides important clues toward improved treatments.

Many of the genetic variants identified in genome-wide association studies occur in segments of DNA that were previously considered to be of little importance because they do not code for functional proteins. These discoveries are leading investigators to decipher the roles these DNA regions play in key cellular functions such as regulating how and when genes are turned on or off. The NIH Encyclopedia of DNA Elements (ENCODE) Project Consortium provides valuable research tools for uncovering such information. In follow-up to a session at its FY 2013 scientific planning retreat, NIAMS is exploring the possibility of leveraging ENCODE resources to generate ENCODE-type data from cells and tissues that are directly relevant to rheumatic, skin, and musculoskeletal diseases. This and other related activities could accelerate the discovery of gene variants that contribute to the risk of diseases within the NIAMS mission, improve knowledge about disease development, and identify potential therapeutic targets.

The NIH recently launched the Accelerating Medicines Partnership (AMP), which is a collaboration between the NIH, the Foundation for the National Institutes of Health, 10 pharmaceutical companies, and several health advocacy organizations. AMP investigators will identify and validate promising biological pathways and targets in three disease areas, including Alzheimer’s disease, diabetes, and the autoimmune disorders, rheumatoid arthritis and lupus. AMP will begin pilot projects lasting 3 to 5 years with the ultimate goal to increase the number of diagnostics and therapies for patients and reduce the time and cost of developing them. As part of the NIH-wide AMP, NIAMS and the National Institute of Allergy and Infectious Diseases are in the early stages of planning a team science research program that will provide investigators with the resources needed to elucidate key molecular signaling networks in rheumatoid arthritis, lupus, and potentially other autoimmune disorders.

NIAMS also supports clinical studies that help patients and their healthcare providers make better-informed decisions. For the past decade, NIH-funded researchers have been monitoring the health of people who have lower-back pain due to intervertebral disk herniation, lumbar spinal stenosis, or degenerative spondylolisthesis. The investigators have developed a rich database of outcomes and a calculator showing possible patient results for physical activity, pain, and overall health after surgical or non-surgical treatment for lower-back pain. As a next step in translating the findings into clinical practice, they are refining the calculator by integrating individual patient characteristics, longer-term outcomes data, information about complications following surgery or the need to have a second procedure, as well as results from other studies.

NIAMS is committed to ensuring that a sufficient number of well-trained basic scientists and clinical researchers are prepared to conduct cutting-edge studies related to musculoskeletal, skin, and rheumatic diseases. The Institute awards a combination of institutional training grants and individual fellowships for this purpose. Recognizing that the transition from mentored research to full independence is a vulnerable period in clinician-scientists’ careers, NIAMS has begun meeting with grantees nearing the end of their clinical or patient-oriented research career development awards to identify challenges and ways to better support them and future career development awardees.

NIAMS is also supporting opportunities for interdisciplinary research to help inform and address Institute mission areas. To encourage established grantees to move beyond their individual disciplines and explore new organizational models for collaborative science, NIAMS reissued its Building Interdisciplinary Research Team (BIRT) awards program. The latest version of the initiative places an increased emphasis on new teams that will conduct highly innovative and potentially high impact basic or translational research. The Institute also provides support that allows clinical research groups to access additional resources from NIH or elsewhere. For example, NIAMS supported a team of scientists to plan a clinical trial in Duchenne muscular dystrophy. Because of the planning efforts, a pharmaceutical company assumed responsibility for funding the randomized, double-blinded, placebo-controlled, phase 3 clinical trial—the largest trial yet conducted in boys with this disease.

Overall Budget Policy: The FY 2015 President’s Budget request for NIAMS is $520.189 million, an increase of $0.851 million or 0.2 percent above the FY 2014 Enacted level.

Program Descriptions and Accomplishments

Arthritis and Rheumatic Diseases: This program advances high-quality basic, translational, and clinical biomedical and biopsychosocial research to treat, cure, and prevent arthritis and other rheumatic diseases. It supports the application of new insights in the fields of genetics, genomics, proteomics, immunology, and imaging to understand how the immune system interacts with various tissues in normal and pathological conditions, and to ensure a continuous supply of new targets on which therapies can be based. Investigators also are testing potential therapies in preclinical animal studies and clinical trials. For example, an international team of researchers recently found that the immunosuppressive drug, mycophenolate mofetil (MMF), often given to lupus patients who have kidney inflammation, reduced signs of cardiovascular disease in a mouse model of lupus. Another recent finding, which can be directly applied to clinical practice, comes from members of NIH’s international Immune Tolerance Network, some of whom also have NIAMS support. The researchers demonstrated that a once-weekly dose of the drug rituximab for one month is as effective as 18 months of a daily immunosuppressive therapy at preventing life-threatening organ damage in people who have severe vasculitis (i.e., granulomatosis with polyangiitis—formerly known as Wegener’s granulomatosis—and microscopic polyangiitis).

Budget Policy: The FY 2015 budget estimate for this program is $104.169 million, an increase of $0.320 million or 0.3 percent above the FY 2014 Enacted level. Program plans for FY 2015 include encouraging investigators to explore the signaling pathways within and between immune cells and their target tissues, with the goal of identifying potential drug targets or diagnostic strategies for autoimmune diseases. In addition, as lead of the Lupus Federal Working Group, NIAMS will continue to facilitate collaborations among the NIH Institutes and Centers, other Federal agencies, voluntary and professional organizations, and pharmaceutical companies with an interest in lupus.

Musculoskeletal Biology and Diseases: This program focuses on understanding the fundamental biology of tissues that constitute the musculoskeletal system, and on translating and applying this knowledge to a variety of diseases and conditions, including osteoarthritis (OA). It supports the development of technologies such as bone and joint imaging, tissue engineering, and regenerative medicine to improve the diagnosis and treatment of skeletal disorders, or to facilitate repair of damage caused by trauma to otherwise healthy tissue. The program oversees clinical research into the treatment and prevention of acute and chronic bone and joint injuries and orthopaedic conditions. For example, a decade-long study of boys and girls who have adolescent idiopathic scoliosis recently demonstrated that wearing a brace to stabilize the spine reduces the need for surgery, and that more hours of brace wear corresponds with higher success rates. Other ongoing, long-term studies are informing the advice surgeons provide to patients who are contemplating surgery to repair anterior cruciate knee ligaments or meniscal tears, or to alleviate lower-back pain.

Budget Policy: The FY 2015 budget estimate for this program is $126.402 million, an increase of $0.382 million or 0.3 percent above the FY 2014 Enacted level. Program plans for FY 2015 include continuing an effort, begun in FY 2013, to promote the use of data and images collected as part of the Osteoarthritis Initiative in studies of the epidemiology and natural history of OA and its risk factors. NIAMS also will continue to encourage identification of molecular and cellular mechanisms underlying progressive deterioration of joint structure and function in OA. The goal is to accelerate the development of strategies to predict who will experience OA, how OA can be prevented, and how it can be treated once joint degeneration has begun.

Bone Biology and Diseases: The Bone Biology and Diseases program covers a broad spectrum of research designed to better understand genetic and cellular mechanisms involved in the build-up and breakdown of bone. It studies regulation of bone remodeling; bone formation, bone resorption, and mineralization; and effects of hormones, growth factors, and other signaling molecules on bone cells. The program supports several large epidemiologic cohorts for characterization of the natural history of osteoporosis, and for identification of genetic and environmental risk factors that contribute to bone disease. Over the past decades, these studies have provided information that health care providers are using to assess people’s bone health. (See Program Portrait: Epidemiologic Studies Explain Osteoporosis, Suggest Fracture-Reduction Strategies, below.) NIAMS also supports a robust portfolio on rare bone diseases and skeletal manifestations of other rare conditions. NIAMS-funded researchers studying neurofibromatosis, for example, are examining how the genetic defect associated with the disease increases patients’ risk of fracture and impairs bone healing. Other studies supported through this program are addressing how the musculoskeletal system interacts with other organ systems, including the nervous system, and how these interactions contribute to diseases such as neurofibromatosis.

Budget Policy: The FY 2015 budget estimate for this program is $65.720 million, an increase of $0.202 million or 0.3 percent above the FY 2014 Enacted level. Program plans for FY 2015 include encouraging investigators to study the cell and mineral changes that lead to atypical femoral fractures—breaks in the upper part of the leg bone that are thought to be a rare side-effect of long-term bisphosphonate treatment for osteoporosis. NIAMS also will promote collaborations and the exchange of information at the agency level through the Federal Working Group on Bone Diseases—an interagency committee led by the Institute.

Muscle Biology and Diseases: This program supports a wide range of basic, translational, and clinical research projects in skeletal muscle biology and diseases. It focuses on the fundamental biology of muscle development, physiology, and muscle imaging. Its overarching objective is to advance the understanding of the role that muscle plays in musculoskeletal and whole body health and, ultimately, to treat or prevent skeletal muscle diseases and disorders (including the muscular dystrophies, inflammatory myopathies, muscle ion channel diseases, disuse atrophy, skeletal muscle injury, and loss of muscle mass associated with aging and diseases). The NIAMS-funded research community has become increasingly interested in the role of muscle stem cells in muscle growth and regeneration. In one recent discovery, researchers determined that muscle stem cells can develop into a type of fat cell, called brown fat, which burns energy instead of storing it. Scientists have been looking for ways to unlock the potential of brown fat to help people lose weight; such a finding could have implications in the treatment of obesity and the health risks associated with it, such as arthritis, type 2 diabetes, and insulin resistance. NIAMS’ translational research portfolio has allowed researchers leveraging the NIH Molecular Libraries Program to identify and test potential therapeutic compounds for myotonic dystrophy. While the molecules that the investigators discovered are not suitable for clinical trials, the findings point the way to molecular modifications that could lead to compounds that are more appropriate for human use.

Budget Policy: The FY 2015 budget estimate for this program is $70.735 million, an increase of $0.217 million or 0.3 percent above the FY 2014 Enacted level. Plans include continued participation in the Senator Paul D. Wellstone Muscular Dystrophy Cooperative Research Centers Program, collaborations with other NIH components and Federal agencies to advance research objectives in the new Action Plan for the Muscular Dystrophies, and efforts to encourage researchers to investigate the molecular processes by which skeletal muscle influences other organ systems.

Skin Biology and Diseases: This program’s support for basic, translational, and clinical research includes work on the developmental and molecular biology of skin, the study of skin as an immune organ, and the genetics of skin diseases. The Institute is pursuing opportunities in developing artificial skin, and imaging technologies for diagnosis and tracking progression of skin diseases. In early 2013, NIAMS-funded investigators published mouse and cell-culture data showing that altering a key protein involved in the development of vitiligo may protect against—or even reverse—the pigmentation loss associated with the skin disorder. As there are currently no long-term effective treatments for vitiligo, the researchers’ overall goal is to test the approach in clinical trials. In addition, NIAMS-supported scientists have published the results of preclinical testing of two different strategies for replacing type VII collagen—the protein that is defective in people who have recessive dystrophic epidermolysis bullosa, a rare blistering skin disease that affects internal tissues as well as the skin, and leaves people prone to infections, scarring, and fatal cancer. In mice, the intravenous treatment strategy appeared to be safe and effective; the topical formulation corrected defects in existing wounds, but could not penetrate intact skin to prevent formation of new blisters. Related experiments revealed that recombinant collagen VII might have general utility as a topical therapy to accelerate wound healing and reduce scarring in other skin diseases or injuries. If successfully translated into a safe and effective cream, ointment, or lotion, this work will be another example of how studying a very rare disease can benefit a large number of people affected by other conditions.

Budget Policy: The FY 2015 budget estimate for this program is $70.474 million, an increase of $0.217 million or 0.3 percent above the FY 2014 Enacted level. Building on the significant gains in understanding itch sensation in recent years, NIAMS will continue to encourage basic and translational research that will lead to more discoveries about the mechanisms of itch sensation and the development of interventions to modulate and control itch in disease. Other FY 2015 activities include efforts to help the scientific community continue to expand its knowledge about how skin communicates with the brain and responds to changes in other organ systems. Ongoing programs that NIAMS will continue to support include a clinical trial of an antibody against a key signaling pathway in moderate and severe atopic dermatitis (a type of eczema).

Intramural Research Program: The mission of the Intramural Research Program (IRP) is to conduct innovative basic, translational, and clinical research relevant to the health concerns of the Institute, and to provide training for investigators who are interested in related research careers. The program conducts basic scientific and clinical studies on the genetics, etiology, pathogenesis, and treatment of a variety of rheumatic, autoimmune, inflammatory, joint, skin, and muscle diseases. The NIAMS IRP consists of basic researchers and physician-scientists who have contributed many noteworthy discoveries. Recently, NIAMS intramural researchers collaborated with NIAMS-funded extramural scientists on a study confirming that use of methotrexate, a common therapy for rheumatoid arthritis (RA), reduced RA patients’ risk of death. Future studies may explore how methotrexate works to decrease mortality rates. NIAMS is also enhancing the IRP’s expertise in rheumatology. The Institute recently recruited new faculty to lead the NIAMS Rheumatology Fellowship and Training Branch and NIH Rheumatology Fellowship Training Program, as well as a new Systemic Autoimmunity Branch that will enhance the Institute’s focus on lupus, RA, and organ damage due to these diseases.

Budget Policy: The FY 2015 budget estimate for this program is $54.165 million, an increase of $0.536 million or 1.0 percent above the FY 2014 Enacted level. NIAMS plans for FY 2015 include maintaining a focus on translational research in order to facilitate patient-oriented studies in the areas of arthritis, musculoskeletal, and skin diseases, including their genetic, inflammatory, and immune underpinnings. NIAMS will also continue a long-standing commitment to multidisciplinary training of rheumatology research fellows to strengthen the pipeline of highly qualified physician-scientists in this field. Both efforts will continue to synergize with the NIAMS Community Health Center facility in Silver Spring, Maryland. NIAMS is also continuing participation in an NIH Funding Opportunity Announcement to promote collaborations between intramural and extramural investigators in order to leverage the unique research opportunities and resources available at the NIH Clinical Center.

Research Management and Support (RMS): NIAMS’ RMS budget supports the scientific, administrative management, and information technology activities associated with the Institute’s day-to-day operations. In FY 2013, the Institute managed more than 1,262 research grants and centers, as well as 38 research and development contracts and 291 individual and institutional full-time research training positions. NIAMS supported 502 clinical research studies, including 82 clinical trials. Recent RMS activities include convening a group of extramural investigators to examine NIAMS’ Centers Program and advise NIAMS’ leadership about how to adapt the Program to better facilitate research opportunities within the NIAMS’ mission. (See Program Portrait: Evaluation of NIAMS Centers Program, below.) In FY 2014, NIAMS will work with researchers, healthcare professionals, and health advocacy organizations to update the Institute’s Long-Range Plan. This revised document will provide a broad outline of scientific opportunities and challenges, and will guide the Institute's priority-setting for FY 2015-2019.

Budget Policy: The FY 2015 budget estimate for this program is $28.524 million, an increase of $0.282 million or 1.0 percent above the FY 2014 Enacted level. Plans for FY 2015 include working with national and community partners to develop and disseminate meaningful health information for racial and ethnic minority populations through its National Multicultural Outreach Initiative (NMOI). NIAMS also will continue to enhance its social media presence through outlets such as Facebook and Twitter, and expects to implement a content management system that will tailor the information displayed on the Institute’s website to the interests of different audiences.
