Activating SMCHD1 to treat Facioscapulohumeral muscular dystrophy

Activating SMCHD1 to treat Facioscapulohumeral muscular dystrophy

The opportunity

  • There is currently no specific treatment available for Facioscapulohumeral muscular dystrophy (FSHD), a genetic muscle disorder caused by abnormal expression in adult cells of the transcription factor DUX4
  • SMCHD1 is an important repressor of DUX4 that possesses enzymatic (ATPase) activity; altered ATPase activity of SMCHD1 has been shown in disease
  • SMCHD1 activation is a potential FSHD therapy

FSHD is a genetic muscle disorder mostly affecting muscles of the face, shoulder blades and upper arms. It is estimated to affect about 1 in 7500-20,000 individuals worldwide. FSHD is caused by DUX4 expression, which is normally silenced in adult cells by SMCHD1 and other epigenetic repressors.

The technology

We have shown that SMCHD1 contains a GHKL-ATPase domain and confirmed that it possesses enzymatic activity. Decreased ATPase activity has been found in FSHD patients suggesting that activation of SMCHD1 activity could be a potential FSHD therapy.

Opportunities for partnership 

We are seeking a partner to co-develop SMCHD1 activators for FSHD therapy.

We have:

  • Foremost experts in SMCHD1, a world class structural biology program and an understanding of SMCHD1 structure  
  • High quality recombinant protein, validated screening assays and capability for structure-guided medicinal chemistry

We are seeking a partner:

  • To invest in our medicinal chemistry program to follow up identified hits from an ongoing fragment-based drug discovery campaign
  • With culture systems of human muscle cell systems to validate activator hits
