  • Psoriatic arthritis
  • Ankylosing spondylitis
  • Plaque psoriasis
  • Crohn’s disease
  • Non-radiographic axial spondyloarthritis (nr-axSpA)

    Clinical studies: How long for Cimzia to work?

    Rheumatoid arthritis

  • In studies, close to 60% of patients with moderate-to-severe rheumatoid arthritis and using Cimzia had reductions in joint pain, and swollen and tender joints in 24 weeks (compared to 14% of patients on placebo).
  • One-quarter and one-third of these patients on Cimzia saw results at 1 to 2 weeks (vs. 6% and 8% of placebo patients, respectively.)
  • At 6 months, patients also reported improvements in independent daily activities such as bathing, dressing, doing chores and errands, and walking.
  • At one year, 69% of patients using Cimzia 200 mg every other week had no further worsening of joint damage as seen on X-rays (compared to 52% of placebo patients).

    • Dosing: In rheumatoid arthritis, the Cimzia recommended dose is 400 mg initially and at Weeks 2 and 4, followed by 200 mg every other week. For maintenance dosing, 400 mg every 4 weeks can be considered.

    Psoriatic Arthritis

  • In studies, 58% of those on Cimzia experienced less joint pain, tenderness, and swelling by 12 weeks (vs 24% on placebo).
  • As early as 1 and 2 weeks, 22% and 33% of Cimzia patients saw an improvement (vs. 7% and 12% of placebo patients at week 1 and 2).
  • An improvement in skin appearance was seen in 62% of patients at 6 months (vs. 15% on placebo).
  • In addition, further joint damage was inhibited at 24 weeks in patients receiving 200 mg every other week of Cimzia, as shown by X-ray.

    • Dosing: In psoriatic arthritis, the Cimzia recommended dose is 400 mg initially and at Weeks 2 and 4, followed by 200 mg every other week. For maintenance dosing, 400 mg every 4 weeks can be considered.

    Ankylosing Spondylitis

  • About 57% of patients with ankylosing spondylitis receiving Cimzia had symptom relief, such as improvements in morning stiffness, tenderness, and back pain after 12 weeks, vs. 37% of those on a placebo
  • At 1 to 2 weeks, 40% and 49% of patients had relief compared to 16% and 28% of patients on a placebo.
  • In addition, improvements in daily activities like bending, gardening, and looking over the shoulder while driving occurred as fast as 12 weeks.

    • Dosing: For ankylosing spondylitis (AS), Cimzia is given as 400 mg initially and at weeks 2 and 4, followed by 200 mg every other week or 400 mg every 4 weeks.

    Plaque Psoriasis

  • In clinical studies of moderate-to-severe plaque psoriasis, 64% of people using Cimzia had clearer skin within 4 months (compared to 3% on placebo). Of this group, 16% saw clearer skin at 4 weeks (vs. 1% on placebo).
  • Within 4 months, 78% of people using Cimzia achieved 75% more clear skin compared to 10% of placebo patients.

    • Dosing: In plaque psoriasis, Cimzia is given as 400 mg every other week. For some patients (with body weight ≤ 90 kg), a dose of 400 mg initially and at Weeks 2 and 4, followed by 200 mg every other week may be considered.

    Crohn’s disease

  • In patients with moderate-to-severe Crohn’s disease, 64% saw results with Cimzia at 6 weeks. This positive effect was extended to 26 weeks in 63% of people, with 48% achieving remission (disease and symptoms no longer active), compared to 36% and 29% of placebo-treated patients, respectively.
  • At 6 months, the quality of life was also improved for 60% of patients (vs. 43% of the placebo group). Symptom relief was seen for bowel symptoms, fatigue, and emotional distress. Engagement in social activities was also improved.
  • Of 24% of patients who had previously received an anti-TNF therapy, 44% responded to Cimzia after 26 weeks (vs. 25% of the placebo group).

    • Dosing: In Crohn’s disease, Cimzia is given as 400 mg initially and at Weeks 2 and 4. If a clinical response occurs, follow with 400 mg every four weeks

    Non-radiographic axial spondyloarthritis (nr-axSpA)

  • In a study of patients with non-radiographic axial spondyloarthritis (nr-axSpA), patients were treated with a loading dose of Cimzia 400 mg initially, and then at 2 and 4 weeks, or placebo; followed by 200 mg of Cimzia every 2 weeks or placebo. Use of NSAIDs, DMARDs, corticosteroids, or opioids were permitted at any time.
  • In this study, 47% of patients had symptom improvement (in back pain, stiffness, and joint swelling) at 52 weeks (vs. 7% of placebo group). Some patients saw an effect at 2 weeks (vs. 1% placebo).
  • At 12 weeks, 33% of patients had less back pain than the placebo group and an improvement in their quality of life (like daily and social activities).
  • Twelve weeks after starting Cimzia, 41% of patients had a reduction in physical disability (such as bending, reaching, and climbing stairs), compared to 9% in the placebo group. At one year after treatment, this effect increased to 50% in the Cimzia group (vs. 13% of patients taking a placebo).

    • Dosing: For non-radiographic axial spondyloarthritis, a Cimzia dose of 400 mg is given initially, and at weeks 2 and 4, followed by 200 mg every other week or 400 mg every 4 weeks.
