Roche (RHHBY) Announces Positive Long-Term Data on SMA Drug

Read MoreHide Full Article

Roche (RHHBY - Free Report) announced new long-term data for the spinal muscular atrophy drug (SMA), Evrysdi (risdiplam), from the open-label extension (n=50) of the pivotal FIREFISH study.

FIREFISH is a two-part study in babies aged 1-7 months at the time of enrolment.

The data reinforced the drug’s sustained efficacy and safety profile in children with type 1 SMA.

Most children enrolled in the study continued to show improvement in their ability to sit, stand and walk without support after four years of treatment with Evrysdi. Importantly, the children who were treated and were alive at the time of the primary analysis were still alive at month 48. Moreover, a majority of infants maintained their ability to feed by mouth and swallow up to month 48.

This was pivotal, as untreated children with type 1 SMA are not expected to survive past two years of age and are never able to sit without support.

Among the infants treated with Evrysdi, 37 infants treated with Evrysdi were able to sit without support for at least 5 seconds at month 48 compared with 35 at month 24; and 36 infants were able to sit without support for at least 30 seconds at month 48, up from 23 infants at month 24. Three infants gained the ability to stand alone and one infant gained the ability to walk alone between months 24 and 48.

Per Roche, Evrysdi’s oral route of administration allows the drug to be distributed throughout the body, systemically increasing SMN protein production, a lack of which is the underlying cause of SMA.

We note that Roche is evaluating Evrysdi as part of a collaboration with the SMA Foundation and PTC Therapeutics.

Apart from FIREFISH, the drug is currently being evaluated in four other trials in SMA patients.

These studies include SUNFISH, a two-part, double-blind, placebo-controlled pivotal study in people aged 2-25 years with Types 2 or 3 SMA; JEWELFISH, an open-label exploratory trial designed to assess the safety, tolerability, pharmacokinetics and pharmacodynamics in people with SMA aged 6 months to 60 years who received other investigational or approved SMA therapies for at least 90 days prior to receiving Evrysdi and  RAINBOWFISH, an open-label, single-arm, multicentre study investigating the efficacy, safety, pharmacokinetics and pharmacodynamics of Evrysdi in babies from birth to six weeks of age (at first dose) with genetically diagnosed SMA who are not yet presenting with symptoms.

Meanwhile, MANATEE is a global phase II/III study evaluating the safety and efficacy of GYM329, an anti-myostatin molecule targeting muscle growth, in combination with Evrysdi for the treatment of SMA in patients 2-10 years of age.

Roche’s stock has lost 2.1% in the year so far against the industry’s growth of 2.2%.

We note that Evrysdi is already a key contributor to Roche’s top line. Pharmaceuticals Division sales increased by 9% in the first quarter and Evrysdi was one of the top five contributors to this growth, apart from Vabysmo, Ocrevus (multiple sclerosis), Hemlibra (hemophilia) and Tecentriq (cancer immunotherapy).

Lower COVID-19 product sales continue to impact the top line. Sales are likely to be impacted further due to the expected sharp decline in sales of COVID-19 products of roughly CHF 5 billion in 2023. Competition from biosimilars for established cancer medicines like Avastin, MabThera/Rituxan and Herceptin also harmed sales.
