IP ALT-803 Followed by SQ ALT-803 for Ovarian Cancer

In this study all patients receive four 8 week cycles of ALT-803 consisting of 4 weekly doses followed by a 4 week rest (no treatment). As it is not known how intraperitoneal (IP) administration (a route of drug administration frequently used for gynecologic cancers) of ALT-803 compares to subcutaneous (SQ) administration, both routes of administration will be tested. The primary objective of this trial is to select one method of delivery for further testing.
