Tesaro, Inc. has opened an expanded access program (EAP) in the United States to make niraparib, an investigational poly (ADP-ribose) polymerase (PARP) inhibitor, available to eligible women with recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer following a complete or partial response to platinum-based chemotherapy.1

EAPs allow patients with a serious or life-threatening disease or condition who are not otherwise eligible to participate in a clinical trial and have no other comparable or satisfactory therapeutic options to access investigational medicines.

US-based health care professionals seeking more information about the niraparib EAP can call Idis Managed Access at 1-877-768-4303 or email [email protected] for further details about niraparib accessibility for eligible patients.
