BAD Biologic Interventions Register BADBIR Dr Kathy McElhone 27th June 2012
Presentation Overview BADBIR 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and patients • Concerns • relatively high cost • potential for serious side effects • efalizumab (marketing license withdrawn in 2009) • anti-TNF agents (serious infections e.g. tuberculosis, certain malignancies e.g. lymphomas, demyelinating disorders, congestive heart failure)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? • Short-term safety of biologics has been evaluated in clinical trials Phase I/II– Phase III • Spontaneous pharmacovigilance • Observational cohorts National registers 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 and NICE All patients treated with biologic agents be registered with BADBIR
Brief History of BADBIR MREC Approval achieved BADBIR Main study BADBIR 1st patient recruited BADBIR Pilot phase Completed n = 143 MREC submission BADBIR Pilot phase started Jul 2008 Aug 2008 Aug 2007 Dec 2006 Mar 2007 Apr 2007
Aim of BADBIR To investigate the long-term outcome of psoriasis patients treated with biologic agents, with particular reference to safety Primary endpoints of interest malignancy infection requiring hospitalisation serious adverse events death
BADBIR Study DesignObservational Cohort Study Inclusion Criteria (both cohorts) • Diagnosis of psoriasis • Aged 16 years or over • Willing to provide written informed consent • Under the care of a dermatologist
BADBIR Study DesignObservational Cohort Study Inclusion Criteria (both cohorts) • Diagnosis of psoriasis • Aged 16 years or over • Willing to provide written informed consent • Under the care of a dermatologist Biologic Cohort Starting / switching BIOLOGIC therapy in last 6 months • adalimumab • etanercept • infliximab • ustekinumab
BADBIR Study DesignObservational Cohort Study Inclusion Criteria (both cohorts) • Diagnosis of psoriasis • Aged 16 years or over • Willing to provide written informed consent • Under the care of a dermatologist Conventional cohort Biologic Cohort (anti-psoriatic therapy) Starting* / switching CONVENTIONAL therapy in last 6 months Starting / switching BIOLOGIC therapy in last 6 months vs. • acitretin • adalimumab • ciclosporin • etanercept • fumaric acid esters • infliximab • hydroxycarbamide • ustekinumab • methotrexate • PUVA • Conventional cohort additional criteria: • Must be biologic naive • * If starting therapy, PASI ≥10 and a DLQI >10
Study Design – Follow-up 6 Monthly Annually Dermatology Team questionnaire 5 YEARS Annually 6 Monthly Patient questionnaire & diary 5 YEARS Flagging for occurrence of malignancy and/or death LIFE LONG Year 0 Year 3 Year 5

Sample Size Calculation • 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: Biologic N = 4000 (per drug) Conventional N = 4000
BASELINE Data collected at baseline Eligible patient signs consent form Consent form faxed to BADBIR DERMATOLOGY TEAM PATIENT Disease Characteristics PASI Current/Previous therapies Co-morbidities Demographics Occupational Status Smoking History Patient reported outcome measures: (DLQI, EQ-5D, CAGE HAQ if co-existing IA) Patient Diary Clinician register patient onto BADBIR database
FOLLOW UP Data collected at each follow-up Patient attends follow—up visit DERMATOLOGY TEAM PATIENT Changes to therapy Adverse events Current disease activity Patient Reported Outcome Measures: (DLQI, EQ-5D, CAGE, HAQ if co-existing IA) Patient Diary (hospitalisations, referrals, new drugs)
130 Centres currently recruiting • 5 in application at R&D departments • 9 centres approved, set-up but • yet to recruit
In conclusion: BADBIR BADBIR established primarily to assess long term safety of biologic agents Other questions attrition rates of the biologic therapies effectiveness of second and subsequent treatments will be available may assist in the development of future guidelines of care. data on the relative safety and effectiveness in large numbers of patients treated with systemic agents such as methotrexate and ciclosporin. BADBIR for future studies e.g. pharmacogenetic, treatment concordance Answers to these questions will enable clinicians to provide more accurate, better quality information to patients commencing both the biologic and the conventional treatments
BADBIR an achievement of olympic proportions Pharma BAD CLRN/R&D Patients and Dermatology Teams UoM Acknowledgements • The dermatology teams for their efforts in registering patients • BAD was provided with restricted income financial support from Abbott, Pfizer, MSD and Janssen Cilag to set-up BADBIR • BAD commissioned the University of Manchester to set-up BADBIR with this financial support http://www.bad.org.uk/site/622/default.aspx http://www.cks.nhs.uk/psoriasis
