A systemic disease in which immune system mistakenly attacks body tissues, causing chronic inflammation of the joints, tissue, and other organs1-3

Ongoing features include:1-3 Chronic destructive synovitis

Chronic joint destruction

Functional disability in untreated patients

Etiology of RA is unknown, although RA may be linked to genetic factors and environmental influences4

Affects 1.3 million adults in the United States1

Left untreated, 20% to 30% of RA patients become permanently unable to work within 3 years of diagnosis2

Life expectancy may be substantially reduced2

Early diagnosis and appropriate therapy can stave off joint damage and reduce comorbidities2

Most deaths in RA are caused by comorbidities1

Deaths could be attributed to disease process, or effects of pharmacotherapies1

58% of patients with RA have ≥ 1 comorbidity, and 25% have ≥ 2 comorbidities2

R-D

Refer to a rheumatologist if the patient shows these symptoms:

• ≥ 3 swollen joints

• Positive “squeeze” test

• Morning stiffness ≥ 30 minutes

Squeeze test indicates pain across second to fifth

metacarpals (MCP), metatarsals (MTP)

What should you ask the patient? • What hurts when you get out

of bed?

• How long does it take to feel

as limber as you are going to

feel for the day?

• When is your pain the worst

(morning or night)?

• Do you smoke?

• Do any members of your

family have RA?

• Can you perform daily

activities (turn faucet handles,

hold toothbrush, dress/bathe

independently)? • What are the things you

cannot do because of your

symptoms?

RA patients have an increased incidence of cardiovascular

disease1

Both traditional cardiovascular risk factors and manifestations of

RA contribute to cardiovascular disease in RA patients2

High grade systemic inflammation in RA may accelerate

atherogenesis3

RA is associated with an unfavorable atherogenic index, with low

HDL. This starts in a pre-RA disease phase4

Venous thromboembolism incidence rate (IR) in RA was 2.4x higher than in

non-RA patients 5

Incidence rates for DVT (RR 2.2) & PE (RR 2.7) higher in RA than in non-RA

patients 5

R-D

Strategies to prevent CVD and mortality must focus on

controlling both traditional CV factors and unique issues

related to RA1

Combination of anti-TNF*-α therapies and methotrexate is

associated with a reduction in the risk of acute myocardial

infarction2-5,8

In long-term outcome study of 19,580 patients with RA, anti-

TNF use associated with reduced risk of mortality (hazard

ratio 0.69), as was methotrexate (hazard ratio 0.84)2

Atherosclerosis in RA may be mediated through conventional

CV risk factors, disease activity, corticosteroid use, and

unfavorable body composition6,7

Conventional x-ray (XR), ultrasound (US), or MRI can be used to improve certainty of diagnosis

The presence of inflammation seen on US or MRI can predict RA progression and are superior to clinical examination

XR of the hands and feet should be obtained initially and should be repeated periodically; if negative US or MRI may be helpful

US and MRI may be used to predict response to treatment and may be useful in measuring disease activity

Patients followed prospectively for 1 year

Radiographic joint damage developed in 19% of patients

Damage correlated with US and MRI evidence of synovitis at

baseline

Conclusions

Clinical assessment of remission may not be sufficient to

identify patients at risk of disease progression

Should MRI and/or US be used to identify patients at low

risk of progression?

Early diagnosis

Newly established 2010 RA classification criteria

Measuring RA disease activity

Quantitatively establish and document a baseline

Compare quantitative RA measurements at progressive time points

Identify ultimate target of therapy—remission (T2T)

Remission or at least low disease activity is the goal

Goal can be reached with monotherapy or combination therapy but

latter is better

Treatment strategy to continuously strive to push disease toward

improvement

Advance therapy in stepwise fashion while continuously measuring

disease to achieve goal—or as close as is reasonably feasible

Can we withdraw biologic if remission obtained? *OPTIMA Trial

*Smolen J et al. Lancet, October 25, 2013

When preliminary diagnosis is made, treatment

begins1

Nonsteroidal anti-inflammatory drugs (NSAIDs) for

pain relief

Glucocorticoids to suppress inflammation

Monitor patient for adverse events

Advise patient on exercise, lifestyle

If there is any evidence of inflammatory

arthritis, refer to rheumatologist < 3 months

after initial diagnosis2

Three Main Classes of Pharmacologic Therapy for Treating RA

DMARDs

Nonbiologics (first line)

• Target immune cells, usually by an

unknown mechanism

• Examples include: methotrexate,

hydroxychloroquine, sulfasalazine,

leflunomide, gold

Biologics (second line)

• Target specific parts of inflammatory

cascade

• Examples include: infliximab,

etanercept, adalimumab, anakinra,

abatacept, rituximab, tocilimumab

NSAIDs Low-dose

Corticosteroids

Adjunctive

(PCP may

initiate)

• No agreement on:

– Efficacy, safety, and adverse effects of low-dose corticosteroids1-4

– Definition of low-dose corticosteroids5

• Low-dose corticosteroids (less than 7.5 mg per day*) may

provide initial relief to RA patients, but relief may mask

disease progression

• Corticosteroids slow radiographic progression (Sharp scores)

in early disease6

– However, not to the degree of traditional DMARDs and/or biologics

• Clinicians must weigh the benefits corticosteroids provide

versus the risk of treatment complications*

The nonbiologic DMARD methotrexate (MTX) is the cornerstone of RA treatment; start with 7.5 mg for better tolerance and increase to 20-25 mg (consider parenteral MTX)

Combination therapy of traditional DMARDs (triple therapy) is more effective than MTX monotherapy

Monotherapy with TNF-α inhibitors has similar efficacy compared with MTX monotherapy

Combination therapy with MTX and a TNF-α inhibitor appears to be more effective than either monotherapy alone, based on ACR criteria

Combination therapy also results in significantly less joint damage, as measured by Sharp scores

Early and aggressive treatment of inflammation reduces hazard ratios for early mortality

Should we use triple therapy initially and if response is not adequate then switch to a biologic?

Many rheumatologists uncomfortable with using triple RX and have adopted the anti-TNF agents in combination with MTX as the treatment of choice after MTX monotherapy

The biologic agents have significantly improved the lives of our patients and have proven surprisingly safe

Will cost-conscious governments and third party carriers dictate our options?

However, biologics are not the final answer as only about 70% of patients respond adequately

Infections

Screen and monitor for bacterial infections, fungal

infections, TB, herpes zoster infection, Hepatitis B and C

Avoid use of biologic agents at least 1 week before and

after surgery (data not evidence-based)

Malignancy

Are there any methods to monitor patients for the

occurrence of malignancy?

Is regular monitoring for malignancy appropriate?

Cardiovascular disease

Screen lipid panel and examine baseline cardiac function

There is a small increased risk of SIEs in large, observational

cohorts, but not in RCTs

This difference is explained by patient selection,

comorbidities, and concomitant drugs

Opportunistic infections rare in patients with RA on TNF

inhibitors, but have unusual presentations and high mortality

No clear malignancy signal, but total length of exposure is

still short

Uncertainty about safety in patients with prior cancer

remains as numbers are small

Ongoing concerns regarding TB, fungal infections, Hepatitis

B and C, pregnancy, congestive heart failure, and PML

Older biologic agents approaching expiration of

patents (monoclonal AB and soluble receptors)

ACA includes more rapid pathway for approval

of very similar but not identical products

Biosimilars in development for infliximab,

etanercept, adalimumab, and rituximab

Cost-savings, safety, and interchangeability all

very critical

Two biosimilars to infliximab approved in

Europe in 2013-none in US

Many therapeutic advances in the treatment of RA

Alternative dosing strategies

Novel therapeutics

Combination therapies

Remission has become a realistic goal for therapy

Despite advances

Many patients fail to achieve a substantial clinical response

(ACR50), even initially

Therapy must be ongoing—no cure or long-lasting response

Joint damage does not heal (ie, treatment delay results in

irreversible damage)

A need for novel strategies to treat RA still exists

Do not test for ANA sub-serologies without a positive ANA and suspicion of immune-mediated disease

Do not test for Lyme disease without history of exposure/physical exam findings

Do not prescribe biologics for RA before a trial of MTX

Do not monitor peripheral inflammatory arthritis with MRI on a regular basis

Do not repeat DEXA scans more often than every two years

Early, aggressive combination treatment affords RA patients the best chance of limiting joint damage, preventing further radiographic progression of disease, and improving quality of life

Recognizing warning signs of RA enables primary care physicians (PCPs) to diagnose the disease early and refer patients to rheumatologists

Close coordination between PCPs and rheumatologists in monitoring toxicities and comorbidities is essential to managing RA patients

There is a disconnect between controlling signs and symptoms and controlling radiographic progression; clinicians need to control both

Therapy decisions based on clinical measurements are superior to decisions based solely on clinician judgment and REMISSION now the goal

True remission should include not only the absence of clinical disease, but cessation of radiographic progression

Knowledge of the basic immunologic mechanisms involved in rheumatic diseases and pharmaco-genomics will permit the development of targeted and individualized therapies
