Safety Study of a Fluorescent Marker to Visualize Cancer Cells

April 20, 2015 updated by: Blaze Bioscience Australia Pty Ltd

A Phase 1 Dose Escalation/Expansion Study of BLZ-100 Administered by Intravenous Injection in Adult Subjects With Skin Cancer

Many types of cancer are primarily treated with surgery and patient survival is directly related to the extent to which the tumor is able to be removed. It is often difficult for surgeons to distinguish tumor tissue from normal tissue or to detect tumor cells that have spread from the original tumor site, resulting in incomplete removal of the tumor and reduced patient survival. In addition, in some sites, such as the brain, it is critical to avoid damage to normal tissue around the tumor to prevent adverse effects of surgery on function. We hypothesize that BLZ-100 will improve surgical outcomes by allowing surgeons to visualize the edges of the tumor and small groups of cancer cells that have spread to other sites in real-time, as they operate.

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
