Refractory gMG in the GCC is a 200 to 300 patient market run by fewer than 15 named neurologists, not a clinical proof problem.

Efgartigimod (Vyvgart) was recently SFDA-registered, 2023-2024, and eculizumab (Soliris) carries an older SFDA registration for generalised myasthenia gravis, but both remain in an early market-development phase, accessed almost entirely through voluntary health insurance at private hospitals with some academic exceptional access; NPHC has no formal refractory-gMG novel-agent programme. GCC myasthenia gravis totals an estimated 800-1,200 patients, of which 200-300 are refractory, IST-inadequate, candidates for a novel agent, and fewer than 50 are currently on either biologic.

The addressable specialist community is extremely small: 10-15 neuromuscular neurologists across KFSH&RC, AUH, HMC, Cleveland Clinic Abu Dhabi, and King Fahd Medical City manage nearly all GCC refractory gMG. Misdiagnosis compounds the sizing challenge: an estimated 30-40% of gMG patients are initially misdiagnosed as thyroid myopathy, since autoimmune thyroid disease is common in Saudi women, and antibody testing is concentrated at KFSH&RC and a few reference labs. VHI approval rates for refractory-gMG novel agents run 60-70% with specialist endorsement; NPHC exceptional access for Saudi nationals without VHI reaches SAR 180,000-250,000 a year for the most severe disease class.

Fewer than 15 neurologists decide adoption here, not a broad sales model.

Five questions this report answers:

Q1 - What must a pre-launch refractory-gMG agent prove against efgartigimod's early GCC market development?

Q2 - How large is the GCC refractory gMG population given the thyroid-myopathy misdiagnosis overlap?

Q3 - What VHI and NPHC groundwork needs to start before launch?

Q4 - What determines whether a pre-launch refractory-gMG agent succeeds commercially in the GCC?

Q5 - What deliverables and sourcing standard back every AXLRx GCC gMG assessment?
