Results with RYSTIGGO

RYSTIGGO is FDA-approved to treat both anti-AChR and anti-MuSK antibody-positive gMG

RYSTIGGO was studied in a large clinical trial (200 participants) specifically for people with gMG

 

The RYSTIGGO clinical trial included adults with gMG who were anti-AChR or anti-MuSK antibody positive.

up to 95%

of people with gMG are anti-AChR or anti-MuSK antibody positive

up to 95%

of people with gMG are anti-AChR or anti-MuSK antibody positive

200 people were divided into 3 groups:

  • Those taking 7 mg/kg of RYSTIGGO (66 people)
  • Those taking 10 mg/kg of RYSTIGGO (67 people)
  • Those taking placebo (67 people)

People in the study:

  • Received 1 dose each week for 6 weeks, in addition to their current gMG treatment
  • Underwent a 6-week treatment period followed by an observation period of up to 8 weeks

UCB is grateful to all the doctors, nurses, and people living with gMG who participated in this trial.

Results of the RYSTIGGO clinical trial:

 

Significant improvement in the activities of daily living

 

RYSTIGGO significantly improved activities of daily living such as breathing, talking, swallowing, and being able to rise from a chair.*

*As determined by improvement in the Myasthenia Gravis Activities of Daily Living (MG-ADL) score from baseline on Day 43 of the study; -3.4 points in the RYSTIGGO-treated group (133 people) vs -0.8 in the placebo group (67 people).

Individual results may vary, and not all people taking RYSTIGGO will experience improvements.

These results were measured using the Myasthenia Gravis Activities of Daily Living scale (MG‑ADL)

Study participants scored themselves on 8 functional activities commonly
affected by gMG. A total MG-ADL score ranges from 0-24, with higher scores indicating more impairment.

 

Rapid improvement by the end of Week 6

 

RYSTIGGO was shown to significantly improve activities of daily living by the end of the 6-week treatment period. Improvements were seen in some participants as early as 1 week after the first dose.

35% (23 out of 66 people) of the 7 mg/kg group and 38% (25 out of 66) of the 10 mg/kg group, compared to 24% (16 out of 67) of the placebo group, as determined by improvement in MG-ADL score.

 

Up to 72% of people responded to treatment

 

Among clinical trial participants receiving RYSTIGGO, a majority experienced improvements in symptoms. Caution must be used when interpreting as conclusions cannot be drawn. Results may vary.

72% (46 out of 64 people) in the 7 mg/kg group and 69% (43 out of 62) in the 10 mg/kg group, compared to 31% (20 out of 64) in the placebo group, as determined by improvement in MG-ADL score from baseline on Day 43 of study. Response was defined as at least a 2-point improvement in MG-ADL score from baseline by Day 43.

 

The first treatment of its kind for anti-MuSK antibody-positive gMG

 

All 12 participants with anti-MuSK antibody-positive gMG who received RYSTIGGO showed improvement in activities of daily living.§ Caution must be used when interpreting as conclusions cannot be drawn. Results may vary.

§As determined by improvement in their MG-ADL score. The study did not compare improvements in anti-MuSK antibody-positive participants to those who were anti-AChR antibody positive and received RYSTIGGO (120 participants).
