Making the days count with VYVGART

Results from a clinical study of VYVGART for IV infusion

Improved daily abilities.
Improved daily abilities.

Significantly improved daily abilitiesDaily abilities assessed included talking, chewing, swallowing, breathing, brushing teeth, combing hair, getting up when seated, and not having double vision or eyelid droop as often.*

68% of patients (44 of 65) had significantly improved daily abilities on VYVGART for IV infusion + current oral gMG treatment vs 30% of patients (19 of 64) on placebo + current oral gMG treatment.

Results were measured by the Myasthenia Gravis Activities of Daily LivingThe MG-ADL scale is an assessment tool that measures the severity of 8 common symptoms of gMG. Each item is scored on a 4-point scale—a score of 0 means “normal,” and a score of 3 means “loss of ability.” The total score can range from 0 to 24 points, with a lower score showing less severe gMG. (MG-ADL) scale in treatment cycleA treatment cycle consists of 4 treatments, 1 given each week. 1 (by week 8).

Reduced muscle weakness.

Significantly reduced muscle weaknessMuscle weakness was measured during actions like making facial expressions, gripping and holding things, holding up limbs, and making eye movements.†

63% of patients (41 of 65) had significantly reduced muscle weakness on VYVGART for IV infusion + current oral gMG treatment vs 14% of patients (9 of 64) on placebo + current oral gMG treatment.

Results were measured by the Quantitative Myasthenia GravisThe QMG scale assesses muscle weakness in gMG based on 13 items. Each item is assessed on a 4-point scale, where a score of 0 represents no muscle weakness and a score of 3 represents severe muscle weakness. Total scores range from 0 to 39, with a lower score meaning muscle weakness is less severe. (QMG) scale in treatment cycle 1 (by week 8).
