PDGFR Alpha Positive Solid Tumours

Soft Tissue Sarcoma (STS) is a cancer of soft tissues that often expresses Platelet-Derived Growth Factor Receptor (PDGFR)α, a potential therapeutic target. PDGFRα is also found in other advanced solid tumours. Olaratumab, a PDGFRα-targeted antibody, may be used to deliver radioactive isotopes for imaging or therapy. This first-in-human study will evaluate zirconium-89-labelled olaratumab (⁸⁹Zr-TLX300-CDx) for imaging in patients with STS, selected PDGFRα-positive solid tumours and identification of patients that may benefit from future treatments.
