A Delphi consensus on integrating novel therapies into the management of generalized myasthenia gravis.

BACKGROUND

The treatment landscape for myasthenia gravis (MG) has evolved with the introduction of novel therapies. An international consensus on patient selection criteria and optimal time to initiate these therapies could improve clinical outcomes and reduce delays for likely beneficiaries.

OBJECTIVE

This Delphi consensus was undertaken by MG specialists from selected European countries to explore gaps in the application of national guidelines and elicit expert opinion in practice.

DESIGN

A mixed-method approach was used; qualitative and quantitative study phases were combined to explore key concepts and reach consensus.

METHODS

The qualitative first phase involved seven healthcare professionals (HCPs) and two patient advocacy group representatives who participated in idea generation. Findings from this phase supported the development of a Delphi survey, which was completed by 16 HCPs in two rounds. This constituted the quantitative second phase of the study. Consensus was defined as ⩾70% agreement or disagreement on a 6-point Likert scale.

RESULTS

In total, 65% of statements achieved consensus. Key findings include-HCPs highly regard international guidelines but find critical discrepancies between the "ideal" scenario and current clinical practices. Consensus was achieved on the importance of incorporating patient-related quality of life in decision-making, despite limited current methods. Consensus was obtained on steroid tapering and treatment-switch criteria based on steroid dose and duration. Consensus was also achieved on suitable patient profiles, including those with persistent symptoms, severe side effects, or needing rapid control.

CONCLUSION

This study recognized that guidelines offer valuable direction but do not replace individualized treatment decisions. This study identified the areas of alignment and opportunities to refine patient selection criteria and treatment-switch categories, particularly to integrate novel therapy use in MG management, highlighting a path to a more patient-centric approach.
