Single Patient Study to Treat Relapsing Polychondritis With Tocilizumab

In this N = 1 study a single known patient with relapsing polychondritis who has failed methotrexate, various anti TNF medications, anti IL1 medication and prolongued glucocorticosteroids will be recruited to receive Tocilizumab 8 mg /kg q 2 weeks iv. The objective is to assess efficacy of tociliuzmab in combination with stable ongoing therapy. Our patient received tocilizumab 8 mg/kg over 1 hour by intravenous infusion every 2 weeks throughout the course of the study. To assess tocilizumab efficacy, the primary objective is the change in physician global assessment on a 100-mm horizontal visual analogue scale (VAS) of disease activity. The secondary objectives were the change in parent global assessment of disease activity on a 100 mm VAS and the glucocorticoid dose in mg per day. Frequency of adverse events was also measured at baseline and after each biweekly tocilizumab infusion.
