Phase phase 2
Targets VEGF, RAF, PDGF, mTOR, FLT-3, KIT, FKBP-12
Sponsor NewLink Genetics Corporation
Start date July 2014
End date July 2016
Trial size 115 participants
Trial identifier NCT02187302, CRLX101-208


This study to evaluate treatment in patients with metastatic renal cell carcinoma (RCC) which has progressed through 2 to 3 prior lines of therapy, with the investigational drug CRLX101 in combination with bevacizumab compared to treatment with a standard of care therapy. The study will compare which treatment resulted in longer time before progression of the RCC. Patients will be treated and followed for progression of their disease on average for up to 6 months.
