A Study Evaluating Safety, Pharmacokinetics, and Therapeutic Activity of RO6874281 as a Single Agent (Part A) or in Combination With Trastuzumab or Cetuximab (Part B or C)

Official Title

An Open-Label, Multicentre, Dose-Escalation, Phase Ia/Ib Study to Evaluate Safety, Pharmacokinetics, and Therapeutic Activity of RO6874281, an Immunocytokine Consisting of Interleukin 2 Variant (IL-2v) Targeting Fibroblast Activation Protein-α (FAP), as a Single Agent (Part A) or in Combination With Trastuzumab or Cetuximab (Part B or C)

Summary:

This first-in-human, open-label, multicentre, Phase Ia/Ib, adaptive, multiple ascending-dose study will evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary anti-tumour activity of RO6874281 as a single agent (Part A) or in combination with trastuzumab or cetuximab (Part B or C).
