Do not know enough about KERX to truthfully answer that. In the long run if they get FDA approval could see 10 , after that depends on who or how they market thier drug. Heard about them months ago but was too caught up in what I already had. Only using KERX as a general guide to what may happen for CLSN currently and THLD later. Think KERX may go quite for awhile now , its had a good run. Staying with CLSN in both stock and call options for the DATA release.
