Remicade therapy shown to increase productivity in psoriatic patients

Feb 3, 2007 - 6:52:29 AM , Reviewed by: Dr. Sanjukta Acharya
"These findings show a relationship between the significant improvements REMICADE-treated patients experienced in psoriasis and improvements in productivity," said Steven Feldman, M.D., Ph.D., professor of dermatology, pathology and public health sciences, Bowman Gray School of Medicine, Wake Forest University. "Such analyses offer further insight into the impact of this chronic inflammatory disease on patient productivity and the effect of intervening with an appropriate biologic treatment, like REMICADE. We look forward to further studies to identify the economic implications of such productivity analyses in a real-world setting."

Level of Evidence
1b - Individual Randomised Control Trial
Key Points of this article
Psoriasis is a chronic immune mediated disease affecting the skin and joints.
REMICADE has been shown to increase production in psoriatic patients.
 
About Remicade
REMICADE is the global market leader among anti-tumor necrosis factor alpha (TNF-alpha) therapies and is the only anti-TNF-alpha treatment approved in three different therapeutic areas: gastroenterology, rheumatology and dermatology. REMICADE has demonstrated broad clinical utility in Crohn's disease (CD), rheumatoid arthritis (RA), ankylosing spondylitis (AS), psoriatic arthritis (PsA), ulcerative colitis (UC), pediatric Crohn's disease (PCD) and psoriasis (PsO). In August 2006, REMICADE received the expanded indication for inhibiting the progression of structural damage and improving physical function in patients with psoriatic arthritis. In September 2006, REMICADE was approved for the treatment of adult patients with chronic severe plaque psoriasis. REMICADE is unique among available anti-TNF biologic therapies. REMICADE is the only anti-TNF biologic administered directly by caregivers in the clinic or office setting.
[RxPG] Investigators reported yesterday at the American Academy of Dermatology annual meeting that patients with moderate to severe plaque psoriasis receiving REMICADEĀ® (infliximab) induction and maintenance therapy experienced significant improvements in productivity at week 10, which were sustained through week 50. After 10 weeks, patients receiving REMICADE 3 mg/kg or 5 mg/kg achieved significant improvements in work and daily activities (2.9 and 3.1, respectively, from baseline) compared to little to no improvement (a mean decrease of 0.1) among placebo-treated patients (P < 0.001), as measured by the Productivity Visual Analogue Scale. Psoriasis is an inflammatory disorder characterized by raised, inflamed, red lesions, or plaques, which can cause physical pain and emotional distress. It is estimated that as many as 7.5 million people in the U.S. have psoriasis, which can present in various forms and can range from mild to severe and disabling.

"These findings show a relationship between the significant improvements REMICADE-treated patients experienced in psoriasis and improvements in productivity," said Steven Feldman, M.D., Ph.D., professor of dermatology, pathology and public health sciences, Bowman Gray School of Medicine, Wake Forest University. "Such analyses offer further insight into the impact of this chronic inflammatory disease on patient productivity and the effect of intervening with an appropriate biologic treatment, like REMICADE. We look forward to further studies to identify the economic implications of such productivity analyses in a real-world setting."

In the Evaluation of Infliximab for Psoriasis in a [REMICADE] Efficacy and Safety Study (EXPRESS II), REMICADE-treated patients demonstrated a statistically significant productivity increase of 2.9 and 3.1 in the 3 mg/kg and 5 mg/kg groups, respectively, from baseline compared with a mean decrease of 0.1 with placebo as measured by the Productivity Visual Analogue Scale (P < 0.001). The Productivity Visual Analogue Scale is a 10-cm scale with a score of zero indicating very impaired productivity and a score of 10 indicating no impairment. Baseline productivity scores among the REMICADE 3 mg/kg, REMICADE 5 mg/kg and placebo groups were comparable at 5.7, 5.6 and 5.6, respectively, indicating impaired productivity.

Increased productivity scores paralleled significant improvements in the role-physical domain (RP) and role-emotional domain (RE) scores of SF-36, an eight-domain questionnaire widely used to assess patient health-related quality of life. In EXPRESS II, at baseline, RP scores in the REMICADE 3 mg/kg, REMICADE 5 mg/kg and placebo groups were relatively low compared with the general population (47.5, 46.6 and 44.8, respectively). At week 10, significant mean increases of 4.1 and 5.1 were reported in the REMICADE 3 mg/kg and 5 mg/kg groups, respectively, compared with little increase (0.8) in the placebo group (P < 0.001). At baseline, RE scores were 47.4, 47.8, and 46.4, respectively. At week 10, significant mean increases of 4.8 and 4.4 were reported in the REMICADE 3 mg/kg and 5 mg/kg groups, respectively, compared with little increase (0.9) in the placebo group (P < 0.001).

At 14 weeks, patients in the REMICADE 3 mg/kg and 5 mg/kg induction groups were randomized to receive scheduled treatment every eight weeks or "as-needed" maintenance therapy with REMICADE. Improvement in productivity scores was better maintained in the scheduled dosing groups versus the as-needed dosing group. The greatest productivity improvement through week 50 was seen in the REMICADE 5 mg/kg every-eight-week maintenance group. Additionally, placebo patients who transitioned to REMICADE treatment at week 16 also achieved improvements in productivity through week 50.

Psoriasis is most commonly diagnosed between the ages of 20 and 30, striking in the prime of people's lives, and the extent of skin involvement varies from mild to severe and disabling. People with severe psoriasis may have large areas of their body covered by lesions, which may crack and bleed. The pain and embarrassment associated with such skin lesions may prevent people from participating in social and work-related activities, and the physical and mental effects of psoriasis have been compared to those of other chronic illnesses such as rheumatoid arthritis, hypertension, heart disease, diabetes and depression. Skin lesions associated with psoriasis often result in feelings of sadness, despair, guilt and anger, as well as in low self-esteem. A person's sense of self-worth can be affected, and in some cases, this emotional turmoil can lead to depression.

"This research further illustrates the correlation and impact of psoriasis on work productivity and demonstrates the substantial physical and emotional burdens faced by those living with this life-altering disease," says Gail Zimmerman, president and CEO, National Psoriasis Foundation. "We at the National Psoriasis Foundation encourage continued research and stress the importance of access to effective therapies, which may help manage a disease that often interferes with work and life activities."

In September 2006, REMICADE was approved in the U.S. for the treatment of adult patients with chronic severe (i.e. extensive and/or disabling) plaque psoriasis who are candidates for systemic therapy and when other systemic therapies are medically less appropriate. The recommended dose is an infusion of 5 mg/kg followed by additional doses at two and six weeks after the first infusion and then every eight weeks thereafter.
