Additional Relevant Details As previously announced, this trial met its primary endpoint, which was defined as 25% progression-free survival at 6 months (PFS-6), in heavily-pretreated patients with late-stage disease. A dose-dependent response was seen, with 35% of patients reaching PFS-6 in the therapeutic dose cohort, versus 25% in a low-dose cohort. Given this positive clinical response, the Company continued to follow patients for overall survival (OS) data, which was not a primary endpoint. Although the trial included a small number of patients and was not powered to show OS differences, the new data show a dose-response and evidence of an overall survival benefit in the cohort of patients treated with multiple therapeutic doses of VB-111, compared to patients who received a single low dose of VB-111 (mOS 761 days versus 469 days; p=0.096).  Only one patient remained alive in the low-dose cohort, compared to a tail of about 50% in the high dose group.
