Abstract
The purpose of this phase II trial was to evaluate the toxicity and antitumor activity of EGEN-001 in platinum resistant recurrent ovarian cancer. Eligible patients had weekly IP infusion of EGEN-001 at a dose of 24mg/m2. Toxicity and antitumor activity were evaluated using CTCAE and RESIST criteria, respectively. Co-primary endpoints were tumor response and survival without progression (PFS) for at least 6months. Survival without progression before going onto a subsequent therapy (EFS) for at least six months was also considered. A total of 58 EGEN-001 cycles were administered to 20/22 enrolled patients (median 2cycles, range 1–9). The most frequently associated adverse events related specifically to EGEN-001 treatment were grade 1/2 fatigue, fever, chills, abdominal pain, nausea, vomiting, anemia, thrombocytopenia, and leukopenia. Three of 20 EGEN-001 treated patients evaluable for toxicity elected to withdraw from the study motivated in part by grade 1 treatment related toxicities. There were no patients with partial or complete response (0%; 90% CI 0–10.9%). Seven (35%) of 16 patients evaluable for response had stable disease, and 9 (45%) had progressive disease. Six (30%) patients had a PFS of greater than six months, although three had gone off study and onto other therapies before six months. The estimated six-month EFS was 15%. The median PFS and OS were 2.89 and 9.17months, respectively. EGEN-001 at the dose and schedule evaluated was associated with some but limited activity and was seemingly less tolerated in platinum resistant recurrent ovarian cancer patients. •Twenty eligible patients with recurrent ovarian cancer were treated with EGEN-001.•There were no tumor responses, and 3 patients were successful by 6-month EFS.•More frequent toxicities included nausea, vomiting, pain, fatigue, and anemia.
