About Ataxia Telangiectasia
Ataxia Telangiectasia (AT) is a rare genetic disease caused by biallelic mutations in the ataxia telangiectasia mutated
(ATM) gene, for which no established therapy is currently available. ATM encodes a PI3Kinase protein shown to play a
pivotal role in response to DNA damage and cell cycle control. Homozygosity for ATM mutations result in a multi-systemic
disorder, involving mainly the nervous and immune systems. The major clinical feature of AT is severe progressive
neurodegeneration from early infancy. Specific features include progressive ataxia of the trunk and limbs, involuntary
movements, oculomotor apraxia, difficulties with speech and swallowing, and delayed peripheral neuropathy. Other
clinical features of patients with the classical phenotype include oculocutaneous telangiectasia, immunodeficiency with
recurrent respiratory tract infections, radiosensitivity and an increased incidence of cancer.

About EryDel
EryDel SpA is a biotechnology company specialized in the development of drugs delivered through red blood cells (RBCs)
by using a proprietary medical device technology. Its most advanced product, EryDex System (EDS) is under late stage
development for the treatment of Ataxia Telangiectasia, a rare autosomal recessive disorder for which no established
therapy is currently available. EryDex has received Orphan Drug designation for the treatment of AT both from the FDA
and the EMA. A completed pilot Phase II trial in AT patients demonstrated statistically significant efficacy of EDS on both
the primary and secondary efficacy measures. An international multi-center, Phase III pivotal study, ATTeST, is being
conducted. EryDel has a pipeline of preclinical programs that use its proprietary RBC’s delivery technology for the
treatment of other rare diseases.
The ATTeST project has received funding from the European Union’s Horizon 2020 research and innovation programme
