About
This study is about an experimental drug called sEphB4-HSA (recombinant albumin fusion protein sEphB4-HSA). This research study will be the first time sEphB4-HSA is given to people. sEphB4-HSA prevents tumor cells from multiplying and blocks several compounds that promote the growth of blood vessels that bring nutrients to the tumor. sEphB4-HSA has shrunk colon, lung, breast, glioma, melanoma, prostate and Kaposi's sarcoma tumors in mice
Full description
PRIMARY OBJECTIVES:
I. To establish the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) of sEphB4-HSA.
II. To describe the dose limiting toxicities and adverse event profile of sEphB4-HSA in patients with advanced solid tumors.
III. To describe the pharmacokinetics of sEphB4-HSA. IV. To describe the anti-tumor activity of sEphB4-HSA as manifested by responses to treatment.
V. To obtain preliminary evaluation of effect of sEphB4-HSA on absolute circulating tumor cell (CTC) numbers as compared with pre-treatment levels using pre- and during treatment CTC. Exploratory evaluation of effect of sEphB4-HSA on downstream protein mediators of the Ephrin pathway (pAKT, pSrc) and their transcriptional target genes (rgs5 and psenen) will be performed.
VI. To collect pilot information to identify a dose or doses with biologic activity. Biologic activity after treatment with sEphB4-HSA will be defined as evidence of drug-on-target effect as manifested by reduction in absolute CTC numbers. Other exploratory evaluations of drug-on-target effect such as increase in transcript levels of psenen or rgs5 may be considered in the assessment of biologic activity.
OUTLINE: This is a dose-escalation study. Patients will be assigned to receive recombinant EphB4-HSA fusion protein intravenously (IV) over 60 minutes in one of the following treatment schedules:
- Weekly treatment - administered on days 1, 8, 15, and 22. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
- Every 2 weeks treatment - administered on days 1 and 15. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
- Every 3 weeks treatment - administered on day 1. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.
