Ovarian Cancer, Platinum-resistant Ovarian Cancer
Conditions
Brief 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.

Polyallergy, bronchial asthma (including aspirin) in history. * Major surgery during the previous 4 weeks (complete wound healing). * Previous chemotherapeutic treatment of the patient according to the scheme GEMCITABINE * Radiotherapy with extended field radiation within the previous 4 weeks or radiotherapy with a limited field radiation within the previous 2 weeks.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Progression-free Survival (PFS) | 2 years since the start of treatment | Median duration of time from start of treatment to time of progression by RESIST 1.1 criterion or death. Progression is defined using RECIST v 1.0 as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Safety of Elenagen in Combination With Gemcitabine | 1 year after the start of treatment | Frequency of drug-related adverse events (AEs) and serious AEs (SAEs) according to NCI CTCAE version 5.0. |
