Description:

Soft Tissue Sarcoma (STS) is a type of cancer that develops in soft tissues such as muscles, tendons, fat, blood vessels, and nerves. STSs generally express a protein called Platelet-Derived Growth Factor Receptor (PDGFR)α, which makes them a target for the development of STS therapies, such as olaratumab. Olaratumab has been identified as a promising candidate to which radioactive substances can be attached for imaging or therapeutic purposes. Thus, this first in human imaging trial aims to study olaratumab combined with a radioactive metal called zirconium-89 (89Zr-TLX300-CDx) as a potential new product that may be used for STS imaging and identification of patients that may benefit from future treatments targeting PDGFRα.
