Details and patient eligibility

About

ASP2151 is an experimental treatment for herpes. Patients undergoing organ and tissue transplantation may be prescribed ciclosporin to suppress their immune system to give the transplant an increased chance of not being rejected. A patient with a compromised immune system is more susceptible to infections such as herpes, which will require treatment.
