Repligen Reports Fourth Quarter ........ "RG2833 for Friedreich’s Ataxia"

9th of June 2011

RG2833 for Friedreich’s Ataxia
We are currently developing histone deacetylase class 1 inhibitors for the treatment of inherited neurodegenerative diseases such as Friedreich's ataxia. Friedreich's ataxia is caused by inadequate production of the protein frataxin which leads to degeneration of the nerves controlling muscle movements. Pending regulatory approval, we plan to initiate a Phase 1 study of RG2833 in Friedreich's ataxia patients in Europe by the end of the year. We are currently engaged in discussions with potential
pharmaceutical partners to evaluate whether partnering this program would increase the trajectory for global development and ultimately maximize the commercial potential of the asset.
