Spinal Muscular Atrophy: Forecast in Asia-Pacific Markets to 2028

Spinal muscular atrophy (SMA) is a rare genetic neurodegenerative disease that primarily affects children. It is characterized by loss of spinal motor neurons, which are specialized cells that control muscle movement.

In recent years the first approved therapy for SMA, Biogen’s Spinraza (nusinersen), has gained marketing authorization in four of the five growth markets (5GM) – Japan, Australia, South Korea and China.

Strong market growth is anticipated across the 5GM over the forecast period. This will largely be driven by increased uptake of Spinraza in the early-to-mid forecast period and the launch of pipeline products from 2020 onwards.

Key unmet environmental and clinical needs in SMA include limited SMA resources and specialists, lack of disease awareness among physicians, low diagnosis rates, limited treatment options and lack of access to disease-modifying therapy for late-onset SMA.

Key Questions Answered

How is SMA currently managed and does this vary by subtype?

To what extent will the launch of pipeline products over the forecast period fulfil the unmet needs in the market?

How will the launch of pipeline products impact Spinraza?

How will growth vary by market?

Key Highlights

In the past three years, Spinraza, the first disease-modifying therapy for SMA has been approved in four of the 5GM – Japan, Australia, South Korea and China.

However, the market remains characterized by significant unmet needs, both clinical (e.g. limited treatment options) and environmental (e.g. lack of disease awareness among physicians).

GlobalData anticipates that four pipeline drugs will launch over the forecast period in the Asia-Pacific (APAC) region. These pipeline drugs are expected to address significant unmet needs for SMA and significantly boost growth in the SMA market across the 5GM.

These pipeline products include Novartis’ Zolgensma (onasemnogene abeparvovec-xioi), a gene therapy administered as a one-time intravenous infusion, as well as risdiplam and branaplam, orally administered small molecules in development by Roche and Novartis, respectively, which have a similar mechanism of action to Spinraza.

Across the 5GM, the SMA market is projected to grow from $308.6M in 2018 to $2.5B in 2018 at a CAGR of 23.3%.
