Progress in rheumatoid arthritis
Progress in Rheumatoid Arthritis

  • Early Disease Recognition

    • Anti-CCP Antibodies (Anti-citrullinated peptide antibodies, ACPA)1

      • Disease-specific serum markers for disease

      • Associated with worse prognosis

      • May appear earlier than other markers (e.g. rheumatoid factor)

    • American College of Rheumatology/European League against Rheumatism (ACR-EULAR) Definitions for RA and Early inflammatory arthritis

    • Increasing primary care provider awareness, education

  • Association of disease and damage with cigarette smoking2

  • Disease-related comorbidities

    • Cardiovascular disease, malignancy, infection, fatigue, anemia

  • Goals of Therapy

    • Decrease signs and symptoms

    • Improve physical function

    • Prevent damage

    • Limit disability


Progress in ra treatment
Progress in RA Treatment

  • Disease-modifying anti rheumatic drugs (DMARDS)

    • Preventing damage and progression

    • No longer “start low, go slow”

  • ACR and EULAR Guidelines for RA Treatment1,2

    • More aggressive treatment regimens

    • Methotrexate as cornerstone of therapy, alone and combinations

  • Target of Therapy: Low Disease Activity State or “Remission”

    • BeST3, TICORA4, others

    • ACR/EULAR/OMERACT Definitions of Low Disease Activity/Remission5,6

  • Approval of Biological DMARDS for RA

    • First agent approved 1999, currently 8 approved US, 9 approved EU

    • Inhibitors of TNF, IL-1, IL-6, T-Cell Costimulation, B Cells

  • Evaluating Strategies of Treatment

    • Treatment paradigms: BeST3, TEAR, induction, step up, step down

    • ACR/EULAR/OMERACT Clinical Trial Outcomes7


Progress in ra outcomes
Progress in RA Outcomes

  • Lower SES associated with worse outcomes1,2

  • Improvement in physical function and HR-QoL3

  • Improvement in work productivity

    • Attenuation of absenteeism, increase presenteeism4

  • Improvement in some comorbidities with treatment

    • Anemia5

    • Cardiovascular6

  • Increased infections

    • Bacterial and atypical/opportunistic (e.g. MTb, fungal, zoster)

    • Highlights need for more surveillance, screening, immunization


Recent progress in spondyloarthritis
Recent Progress in Spondyloarthritis

  • Disease recognition

    • Development and revision of Diagnostic and Classification Criteria for Psoriatic Arthritis1 and Ankylosing Spondylitis2

    • Active international consortia to study these diseases (e.g. GRAPPA, ASAS, CASPAR)

  • Disease-related comorbidities recognized: cardiovascular disease3

  • Approvals of several drugs for Psoriatic Arthritis

  • Approvals of several drugs for Ankylosing Spondylitis

  • Data-driven, Consensus-based Treatment Recommendations3,4

  • Improvement in Physical Function and QoL5

  • Disease modification demonstrated in PsAand under study in AS


Recent progress in juvenile arthritis
Recent Progress in Juvenile Arthritis

  • Research consortia and clinical networks (e.g. PRINTO, CARRA) to concentrate care and facilitate investigation

  • Approvals for drugs in JIA

    • Established Regulatory Pathway

    • Ethical Clinical Trial Designs (Withdrawal/Flare)

  • Improved clinical outcomes

  • Concerns re: longer term safety surveillance for adverse effects (malignancy, lymphoma, leukemia1, and infection)

  • Cryopyrin-Associated Periodic Syndromes2

    • NOMID, Muckle-Wells, Familial Cold Autoinflammatory Syndrome

    • IL-1 inhibitors approved for treatment (including orphan drug indication)

  • Critical shortage of Pediatric Rheumatologists3

    • Lobbying efforts for Arthritis Prevention and Cure Act US Congress


Recent progress in gout
Recent Progress in Gout

  • Revised Diagnostic and Treatment Guidelines1,2

  • Identification of genetic loci for hyperuricemia3

  • Recognition of effects of chronic gout:

    • Reduction in HR-QoL

    • Increase in health care utilization4

  • Better understanding of gout-related comorbidities

    • Metabolic syndrome5

    • Cardiovascular disease6

  • Approval of new drug for gout; additional agents under investigation


Potential impact of health care systems on outcomes
Potential Impact of Health Care Systems on Outcomes

  • Access to medical care

  • Access to specialist evaluation

  • Access to medications

    • Differing requirements for prescribing/continuation

    • Country-to-country variability

    • Insurer-to-insurer variability

  • Access to clinical trials

  • Health literacy

  • Local infection concerns (e.g. MTb)

  • Cost


Ongoing research agenda
Ongoing Research Agenda

  • Real World Risk/Benefit and Cost/Efficacy Analysis

  • Methods to Assess Effectiveness

    • Additional outcomes: employment, disability, joint failure, participation, comorbidities (e.g. CVD)

    • Patient-reported outcomes (e.g. PROMIS, WHO/ICF)

  • Common Data Capture for Registries for Safety and Efficacy

    • NDBRD, CORRONA, BSBR, RABBIT, BIOBADASER, QUEST-RA, TETRAD, etc,

  • Enhanced Post-marketing Surveillance to Capture Rare Adverse Events

    • patient-years of exposure vs. patient-years)

  • Ethical Considerations in Clinical Trials1

    • Whom to study in an era of effective therapy

    • Maintenance of clinical equipoise

  • Developing Outcome Measures for Novel Study Designs

    • Induction/withdrawal, tapering (e.g. “flare”)2

    • Treatment Strategy and Head-to-head Comparison studies

    • “Biosimilars” and Small molecules

  • Screening and prevention of risk (e.g. TB screening, immunization)
