British Association of Dermatologists’ Biologic Intervention Register (BADBIR)Update November 2007
Aim of the Register • To investigate the long-term outcome of psoriasis patients treated with biologic agents, with particular reference to safety • Primary endpoints of interest • anymalignancy • any infection requiring hospitalisation • serious adverse events • death
Subsidiary Aims • Long-term effectiveness data • Evaluate differences in effectiveness between agents • Assess whether sequential therapy with multiple biologic agents acts synergistically to increase the risk • Assess whether sequential therapy with conventional systemic anti-psoriatic therapy and biologic agents acts synergistically to increase the risk
Study Design • Prospective observational cohort study • 5 years active follow-up • Compare rates of events in 2 cohorts of psoriasis patients
Eligibility Criteria • Age ≥ 16years • Severe psoriasis(definition: PASI ≥10 and DLQI >10) • Informed consent • Under care of a UK dermatologist Recommendation from BAD and NICE All patients treated with biologic agents be registered with BADBIR
Observational study vs Biologic Cohort Conventional cohort (anti-psoriatic therapy) • Commencing biologic therapy in last 6 months • infliximab • etanercept • efalizumab • Starting or switching conventional anti-psoriatic therapy • PUVA • MTX • ciclosporin • acitretin • fumaric acid esters • Biologic naïve
Sample Size • Power to detect a 3-4 fold increase in skin cancer • Baseline risk in psoriasis • Non melanoma skin cancer = 100/100,000pyrs • Accounting for losses to follow-up and deaths, requires: Biologics: N = 4000 (per drug) N = 4000 Controls:
Pharmocovigilance (1) Scientific epidemiological study (2) Regulatory authority purposes (on behalf of the companies) • Reporting/monitoring SAE data at specified time points

Data Collection • Dermatology Team – web based transfer • Patient – paper based questionnaires • Website: www.badbir.org
Website(under construction) www.badbir.org
Funding • To help towards time spent collecting this data • The following payment plan is planned • Fully completed baseline form: £100 • Fully completed follow–up form: £50 • (total of 8 follow-up forms over five years)
Location of Pilot Centres • Seven centres • All have LREC approval • 5 have R & D approval • 25 patients have been registered in the pilot phase
Procedure for gaining ethical approvalsPrincipal Investigator – Consultant Dermatologist

In conclusion: BADBIR • Will help to answer important questions about long term safety of both biologic and systemic anti-psoriatic therapy • Enable us to provide more accurate, better quality information to patients commencing on both the biologic and the conventional treatments • Importance of Nurses involvement • Identified as key to the management of patients on biologic therapy
