March 2023:
Outcomes for those with SMA Type 2 or 3, aged 2 – 25 years
Patients enrolled via Part 1 of the trial
Patients involved in Part 1 continued to receive treatment at the dose selected from the 12-week dose-finding study.
- Risdiplam significantly improved motor function after 48 months of risdiplam treatment:
- MFM-32 (Motor function measure which assesses 32 items) total change from baseline was greater in patients receiving risdiplam compared with natural history data.
Patients enrolled via Part 2 of the trial
- Risdiplam significantly improved motor function after 36 months of treatment:
- The proportion of patients demonstrating a marked improvement (change ≥3 points) or stabilisation (change ≥0 points) in MFM-32 score were more likely in people who were on risdiplam than those in the untreated group.
February 2024:
Independent living and measuring what matters
Roche has developed the SMA Independence Scale-Upper Limb Module (SMAIS-ULM). This has been done in close partnership with CureSMA, SMAEurope, and the SMA Foundation. The aim is to measure the level of support needed to perform activities of daily living (ADL) and to better capture the patient and caregiver experience.
At the February 2024 SMA Europe congress, Roche presented a review of the SMAIS-ULM data in Part 2 of the SUNFISH trial.
Across all sub age groups the results showed that a larger proportion of those treated with risdiplam were likely to maintain or gain independence in their daily living activities than those on placebo:
| Patient ages 12 – 25 years | Maintained or Gained Independence in Activities of Daily Living | |
|---|---|---|
| Treated with Risdiplam | Placebo | |
| Patient-reported outcome | 69.8% | 39.1% |
| Caregiver-reported outcome | 66.4% | 38.3% |
