Biologics A substance that is made from a living organism or its products. Biological drugs include antibodies, interleukins, and vaccines. Complex mixtures whose structure are not easily identified or characterized. Biologics can be composed of sugars, proteins or complex combinations of these substances.

Biosimilars A biosimilar is a biological medicine highly similar to another already approved biological medicine (the 'reference medicine').

Drivers for use High costs of originators Biosimilars Huge part of NHS budget Biosimilars 20-40% less expensive Similar efficacy and safety Provoke revision of originator costs as well ?Allows wider access to these therapies

NHS England Policies NHS England Interim Guidance for RTX (2013) Allows off-licence use NICE Approved Belimumab (2016) Managed Access Scheme** Specialised Rheumatology Centres Register patients in BILAG Biologics Register
Interim Policy for Rituximab in SLE (2013) ‘Refractory disease’: SLE diagnosis Persistently Active Disease (BILAG A x 1 or 2 Bs OR SLEDAI >6) Failure to be controlled on 2 or more ‘standard’ agents inc MMF or Cyclophosphamide. Unacceptably high-dose of corticosteroids on a regular basis to control disease (> 10 mg prednisolone daily) This population should be: Offered clinical trials Registered on a national safety register (BILAG BR)
Belimumab Approval in UK (2016) An add-on treatment for active autoantibody-positive SLE in adults only if all of the following apply: Evidence for serological disease activity (defined as positive anti-double-stranded DNA and low complement) AND a SELENA-SLEDAI score ≥ 10 despite standard treatment; Treatment is continued beyond 24 weeks only if the SELENA-SLEDAI (SLEDAI –2K) score has improved by 4 points or more; Under the conditions for data collection, monitoring, patient consent, cost to the NHS, and review by NICE as laid out in sections 5 and 6 of the full guidance document (BILAG registry).

Belimumab Approval in UK (2016) Managed Access Agreement (MAA) between NICE, the University of Manchester (acting on behalf of BILAG), Lupus UK, NHS England and GSK. A real-world research study to collect additional data on belimumab as part of the NHS England ‘commissioning with evaluation’ process. Only Specialised Rheumatology Centres who are contributing to the BILAG Biologics Registry (BILAG-BR) can access funding for belimumab as part of the NICE guidance. Funding is limited to a maximum of 300 “responder” patients NICE reserves the right to withdraw approval for belimumab after this additional analysis is completed.
BILAG Biologics Register Aim To examine the safety and ‘real-world’ effectiveness of biological therapies in the management of lupus in the UK, compared to standard therapies
Observational Cohort Study Information from patients in Group 1 Group 1: Patients with lupus starting biologic therapy 0 months 6 months 12 months Annual questionnaires for at least 2 more years Information collected by the hospital team for at least 3 years COMPARE Group 2: Patients with lupus starting a new standard therapy Information from patients in Group 2
How are doing in with biologics in SLE (SSc and other CTDs)? Could do better!!

CTD management New treatments have been slow to develop Some have evidence to support their use Very difficult health funding environment Biosimilars are providing ‘competition’ in the market and drive down costs Observational Registers: Assesses ‘real world’ effectiveness and safety Helps support access to treatment Helps build the evidence base
CTD management Most treatments have ~40-50% response rate Significant overlap in the underlying mechanisms of these conditions We need to better understand subsets Within a particular condition Across related conditions (shared inflammatory drive)
