Cergutuzumab Amunaleukin in Combination with Atezolizumab in Patients with Carcinoembryonic Antigen-Positive Advanced/Metastatic Solid Tumors.

ABSTRACT:

Purpose

Cergutuzumab amunaleukin (CA) is an immunocytokine comprising a variant form of interleukin 2 (IL2) [constructed to avoid CD25 binding and regulatory T-cell (Treg) stimulation] fused to a carcinoembryonic antigen (CEA)-targeted antibody. This phase Ib open-label, multicenter dose-escalation and -expansion study (NCT02350673) evaluated the safety, activity, pharmacokinetics, and pharmacodynamics of CA plus atezolizumab in patients with advanced/metastatic CEA-positive solid tumors.

Patients and methods

Patients received escalating doses of CA (6-20/25 mg) with fixed dosages of atezolizumab (840 mg) every 2 weeks or escalating dosages of CA weekly (10-15/20 mg) with fixed dosages of atezolizumab (1,200 mg) every 3 weeks. Primary objectives include maximum tolerated dos
