Detailed Description
PRIMARY OBJECTIVES:
I. To estimate the efficacy of recombinant EphB4-HSA fusion protein (sEphB4-HSA) in patients with metastatic castration resistant prostate cancer (mCRPC) as measured by confirmed prostate specific antigen (PSA) response rate.
SECONDARY OBJECTIVES:
I. The safety and tolerability of sEphB4-HSA in patients with mCRPC according to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version (v) 5.0.
II. To assess the time to PSA progression. III. To assess overall response rate in patients with measurable disease using Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 (soft tissue) and Prostate Cancer Working Group 3 (PCWG3) (bone) criteria.
IV. To assess radiological progression free survival (rPFS) using RECIST 1.1 (soft tissue) and PCWG3 (bone) criteria.
EXPLORATORY OBJECTIVES:
I. To explore molecular changes associated with EphB4 and ephrinB2 expression in tumor specimens (primary and/or metastatic tissue).
II. To explore association of response with molecular biomarkers including aberrations in the PI3K pathway, MYC and TP53.
III. To assess immune cell infiltration of tumors in biopsies. IV. To assess circulating immune changes associated with treatment.
OUTLINE:
Patients receive recombinant EphB4-HSA fusion protein intravenously (IV) over 60 minutes on day 1. Treatment repeats every 14 days for cycles 1-6 and then every 21 days for subsequent cycles. Patients may continue to receive sEphB4-HSA treatment until no longer clinically benefiting (PCWG3), unacceptable toxicity, treatment delay >= 4 weeks, or prohibitive illness/change in patient?s condition, or patient decides to withdraw from study.
After completion of study treatment, patients are followed up at 30 days and then every 6 months for up to 1 year.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Prostate Specific Antigen (PSA) Response Rate
Time Frame: Up to 1 year
|
Assessment of confirmed PSA response rate is the proportion of subjects who received at least 1 dose of the study drug achieving a post-treatment PSA partial response or complete response as defined by PSA response criteria. PSA response criteria: These definitions are intended to characterize the PSA changes on study for the purpose of reporting of results. Complete Response (CR): Undetectable PSA (<0.2 ng/ml) that is confirmed by another PSA level at no less than 4 weeks interval (+/- 3 days). Partial Response (PR): Decrease in PSA value by > 50% that is confirmed by another PSA level at no less than 4 weeks interval (+/- 3 days). Stabilization(SD): Patients who do not meet the criteria or PR or PD for at least90 days on the study will be considered stable Progression (PD): 25% increase over baseline or nadir whichever is lower and an increase in the absolute value of PSA level by2 ng/ml that is confirmed by another PSA level at no less than 4 weeks interval. |
