A randomized phase II trial of interleukin-2 and interferon-α plus bevacizumab versus interleukin-2 and interferon-α in metastatic renal-cell carcinoma (mRCC): results from the Danish Renal Cancer Group (DaRenCa) study-1
2018
AbstractBackground: Interleukin-2 (IL2)-based immunotherapy is curative for a small subset of patients with metastatic renal-cell carcinoma (mRCC). Preclinical data suggests that bevacizumab (BEV), a humanized anti-VEGF monoclonal antibody, has potential immunomodulatory effects by permitting efficient natural killer (NK) cell-mediated killing and by reverting immune suppression.Patient and methods: We performed a randomized phase II study comparing IL2/IFN (interferon)/BEV with IL2/IFN in favourable/intermediate-risk mRCC patients. One hundred and eighteen patients received IFN 3 MIU subcutaneously (sc) daily and IL2 2.4 MIU/m2 sc twice daily, 5 days per week for two consecutive weeks every 28-day-cycle, for 9 months; or supplemented with BEV 10 mg/kg, every 2 weeks intravenously (iv) until progression, unacceptable toxicity, or 1 year following no evidence of disease (NED). Primary end point was progression-free survival (PFS).Results: Baseline characteristics were well-balanced between the two arms; me...
