Summary: Phase II, two arm prospective study of efficacy and safety of ELENAGEN in combination with gemcitabine in comparison with gemcitabine alone in patients with platinum-resistant ovarian cancer.

Detailed description: The purpose of this clinical study is to evaluate safety and efficacy of ELENAGEN, a novel anticancer therapeutics (plasmid DNA encoding p62/SQSTM1) protein, as an adjuvant to chemotherapy with Gemcitabin (GEM) in patients with advanced platinum-resistant ovarian cancer. This is a prospective randomized multi-center study with two arms. Gemcitabine 1000 mg/m2 days 1,8 every 3 weeks) is administered in both arms: In the Chemo arm (n = 20) Gemcitabine is the only treatment, and in the ELENAGEN arm (n = 20) GEM was supplemented with ELENAGEN (2.5 mg i.m. weekly). The primary endpoint is progression-free survival (PFS), and the secondary endpoint is safety.
