Immunosuppressant biologic treatment in rheumatology

Warning

Information for general practitioners

The aim of treatment is to suppress disease activity and preserve joint/organ function in the inflammatory arthropathies/SLE and vasculitides for those who have failed or are intolerant of methotrexate. Most are co-prescribed with methotrexate for increased efficacy.

At time of writing there are currently 5 licensed TNF inhibitors (TNFi) and 10 non-TNFi biologics accepted for use in NHS Scotland, not including biosimilars:

  • Adalimumab (Humira, Amgevita)
  • Certolizumab Pegol (Cimzia)
  • Etanercept (Enbrel and biosimilars Benepali and Erelzi)
  • Golimumab (Simponi)
  • Infliximab (Remicade and biosimilars, Remsima, Inflectra and Flixabi)
  • Abatacept (Orencia)
  • Rituximab (Mabthera and biosimilars Truxima, Rixathon and Tituxan)
  • Tocilizumab (RoActemra)
  • Sarilumab (Kevzara)
  • Secukinumab (Cosentyx)
  • Ixekizumab (Taltz)
  • Ustekinumab (Stelara)
  • Guselkumab (Tremfya)
  • Upadacitinib (Rinvoq)
  • Baricitinib (Olumiant)
  • Tofacitinib (Xeljanz)
  • Filgotinib (Jyseleca)
  • Anakinra (Kineret)
  • Belimumab (Benlysta)
  • Apremilast (Otezla) is immunomodulatory not immunosuppressant

Dosage

  • Varies according to individual drug
  • Most are self-administered subcutaneously, but some can be used IV or SC
  • Rituximab and Belimumab are IV
  • Infliximab IV or subcutaneous.
  • JAK inhibitors (jakinibs) are oral

 

Vaccination

  • Pneumococcal and annual flu vaccination is recommended prior to treatment
  • Passive immunization with VZIG is recommended if newly exposed to chicken pox
  • No live vaccines can be given, including Herpes Zoster vaccination

 

Monitoring procedure

  • If the patient is receiving standard DMARDs continue usual monitoring for that drug.
  • If on biologics alone - FBC, ESR, and LFTs monthly for 3 months, then 6 monthly unless advised differently by rheumatology, 
  • Exceptions are Tocilizumab and Sarilumab - require monthly FBC + lipids at 3 months

 

Stop treatment if:

  • Evidence of active infection or during antibiotic therapy (then restart unless the infection was serious/life threatening)
  • Significant open wounds
  • Planned or current Pregnancy, pruritis/rash or symptoms of significant allergy
  • Suspected demyelination
  • Tocilizumab and Sarilumab - stop if new abdominal symptoms (diverticulitis risk)
  • Rituximab/Belimumab - stop if new cognitive/psychiatric/neurological symptoms - exceptionally rarely PML
  • WCC -<3.5 - withhold and discuss with rheumatology
  • Neutrophils <1.5
  • Platelets <140
  • AST or ALT >3 times upper limit normal

 

Duration of treatment and time to response

  • Treatment is continued indefinitely as long as it remains effective and without side effects
  • Biologics vary in their time to response – but they are generally stopped after 3 months if no benefit
  • During this period there are likely to be continued symptoms or signs of disease activity
  • It is reasonable to use IM Depomedrone 80mg or Triamcinolone (Kenalog) 80mg

 

Flares

  • Unfortunately Biologic drugs will not prevent all flares
  • Manage fares with IM Depot steroid as outlined under 'duration of treatment and time to response'
  • If increasing frequency of flares, contact the rheumatologist

 

Contraindications

  • Pregnancy (though early data reassuring - especially for Certolizumab Pegol)
  • Breastfeeding (can breastfeed on Adalimumab and Certolizumab Pegol). Note: B_Live vaccines to infant contraindicated for 5 months in general after mother stops biologic agent (including Rotavirus vaccine)
  • Active infection
  • Open leg ulcers
  • previously infected prosthetic joint (unless completely removed)
  • Septic arthritis in the last year
  • HIV or Hepatitis B carriers (usually)
  • Previous malignancy within last 5 years (usually)
  • NYHA grade 3 heart failure
  • Demyelinating disease

 

Relative contraindications

  • Uncontrolled diabetes
  • Pulmonary fibrosis
  • Bronchiectasis
  • PUVA >1000 Joules
  • NYHA grade 1/2
  • previous TB or positive PPD test
