Abstract Details

Pooled Safety Data from the Risdiplam (RG7916) Clinical Trial Development Program
Child Neurology and Developmental Neurology
P8 - Poster Session 8 (8:00 AM-9:00 AM)
5-015

To describe the longer-term safety profile of risdiplam (RG7916) in individuals who have participated in the FIREFISH, SUNFISH, JEWELFISH and RAINBOWFISH studies.

Spinal muscular atrophy (SMA) is a severe, progressive neuromuscular disease caused by reduced levels of survival of motor neuron (SMN) protein due to deletions and/or mutations of the SMN1 gene. A second gene, SMN2, produces only low levels of functional SMN protein. Risdiplam is an orally administered, centrally and peripherally distributed SMN2 pre-mRNA splicing modifier that increases the levels of functional SMN protein.

The risdiplam clinical development program consists of four studies in a broad population of individuals with SMA:

  • FIREFISH (NCT02913482) aims to assess the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and efficacy of risdiplam in infants with Type 1 SMA aged 1–7 months
  • SUNFISH (NCT02908685) aims to evaluate the safety, tolerability, PK/PD and efficacy of risdiplam in patients with Type 2 or 3 SMA aged 2–25 years
  • JEWELFISH (NCT03032172) aims to assess the safety, tolerability and PK/PD of risdiplam in patients with SMA aged 6 months–60 years previously enrolled in Study BP29420 (MOONFISH) with the splicing modifier RG7800 (RO6885247) or who received previous treatment with nusinersen (SPINRAZA®), olesoxime or onasemnogene abeparvovec-xioi (ZOLGENSMA®)
  • RAINBOWFISH (NCT03779334) aims to investigate the efficacy, safety and PK/PD of risdiplam in newborns aged from birth to 6 weeks with genetically diagnosed and presymptomatic SMA.

Previous analyses from FIREFISH Part 1, SUNFISH Part 1 and JEWELFISH have shown no drug-related safety findings leading to withdrawal from treatment following risdiplam treatment for up to 32.3 months in 158 patients (data-cut: 28th June 2019 for FIREFISH, SUNFISH and JEWELFISH). We will present pooled safety analyses from FIREFISH Parts 1 and 2, SUNFISH Part 1 and JEWELFISH.

This analysis will add to the understanding of the longer-term safety profile of risdiplam.
