Background: On 21st January 2020, the FDA approved Tepezza (teprotumumab-trbw) for the treatment of active Graves' orbitopathy (GO) in adults. This approval was based on positive results from two multinational randomised double-blind placebo-controlled clinical trials. Discussion: This article discusses the outcomes of those trials and the potential role of teprotumumab in altering current treatment paradigms in Graves' orbitopathy. Future challenges are explored, including the need to confirm its disease-modifying effect, to establish its optimal position in the treatment pathway, and to define the appropriate subset of patients who would benefit from its use. Conclusions: The results from these two large clinical trials have shown teprotumumab to have remarkable effects on multiple clinical outcomes in GO, particularly in its ability to reverse proptosis. It may herald a new era in the treatment of thyroid eye disease and could offer an alternative to surgery and its associated complications. Additional studies will continue to shape the treatment of GO and define the role of teprotumumab within the treatment paradigm. [ABSTRACT FROM AUTHOR]

Background: Blepharospasm and hemifacial spasm are debilitating conditions that significantly impact on patient quality of life. Cyclical treatment with botulinum toxin injections offers temporary relief, but the duration of treatment efficacy is variable. The standard model of patient care defines routine fixed-time based scheduled treatment cycles which may lead to unnecessarily frequent treatment for some patients and experience of distressing symptoms in others, if symptoms return before the scheduled follow-up period.Methods/design: A randomised controlled trial will compare a patient-initiated model of care, where patients determine botulinum toxin treatment timing, to the standard model of care in which care is scheduled by the clinical team. A sample of 266 patients with blepharospasm or hemifacial spasm will be recruited from Moorfields Eye Hospital (MEH), London. The trial will be accompanied by a mixed-methods evaluation of acceptability of the new service. Patients who meet eligibility criteria will be assessed at baseline and those in the intervention group will be provided with instructions on how to book their own treatment appointments. Patients in both groups will be followed up 3 and 9 months into the trial and all patients will be returned to usual care after 9 months to meet safety protocols. Primary outcome measures include disease severity (questionnaire), functional disability (questionnaire) and patient satisfaction with care (questionnaire). Secondary outcomes include disease-specific quality of life (questionnaire), mood (questionnaire), illness and treatment perceptions (questionnaire and semi-structured interviews), economic impact (questionnaire) and acceptability (questionnaire and semi-structured interviews).Discussion: This trial will assess the effectiveness and cost-effectiveness of a patient-led care model for botulinum toxin therapy. If the new model is shown to be effective in reducing distress and disability in these populations and is found to be acceptable to patients, whilst being cost-effective, this will have significant implications for service organisation across the NHS.Trial Registration: UK Clinical Research Network (UKCRN) Portfolio 18660.
