BAD Biologic Interventions Register (BADBIR )
An updateNovember 2009
Presentation Overview• Project rationale • Brief history of BADBIR
• Aim and study design
• Data collection
• Conclusions
The advent of biologic agents
• Has been met with:–Considerable enthusiasm from both
clinicians and patients
–Concerns • relatively high cost• potential for serious side effects
– efalizumab (recently had marketing license withdrawn) – anti-TNF agents (serious infections e.g. tuberculosis,
certain malignancies e.g. lymphomas, demyelinating disorders, congestive heart failure)
How is Potential Harm of Biologic Therapy assessed?
Phase I/II– Phase III
• Spontaneous pharmacovigilance
• Observational cohortsNational registers
Short-term safety of biologics has been evaluated in clinical trials
Some long-term safety data on anti-TNF drugs available from use in other conditions e.g. inflammatory arthritis, Crohn’s disease
Rationale for BADBIR
Patients with severe psoriasis are likely to
• be obese
• smoke
• abuse alcohol
• have a high risk of cardio-vascular disease
• be exposed to different types of drugs, e.g. phototherapy
• Therefore, data on the safety of biologic use in other conditions cannot be directly extrapolated to psoriasis
Recommendation from BAD
All patients treated with biologic agents be registered with BADBIR

3 easy steps to getting involved !
Apply for R & D approvalStep 1
Step 2 Evaluate your dermatology centre infrastructureConsider how BADBIR will be integrated into standard care
The BADBIR Study Co-ordinator will visit to provide the user name and password and training on the on-line data collection process
Step 3
Contact BADBIR – we will prepare all documentation
You are now ready to register patients
www.badbir.org.uk
Consider preparing a business case for a specialist nursing service to assist in management of patients on biologic/systemic therapy
Post R & D Approval
It is essential that all relevant staff are present for this meeting

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 both the biologic and the conventional treatments
• The dermatology teams for their efforts in registering patients
• BAD was provided with restricted income financial support from Abbott, Wyeth and Schering Plough to set-up BADBIR
• BAD commissioned the University of Manchester to set-up BADBIR with this financial support
