Study Evaluating the Safety, Pharmacokinetics (PK), Pharmacodynamics (PD), and Therapeutic Activity of RO7009789 With Vanucizumab or Bevacizumab in Participants With Metastatic Solid Tumours

Official Title

An Open-Label, Multicentre, Dose Escalation Phase Ib Study With Expansion Cohorts to Evaluate the Safety, Pharmacokinetics, Pharmacodynamics, and Therapeutic Activity of RO7009789 (CD40 Agonistic Monoclonal Antibody) in Combination With Vanucizumab (Anti-Ang2 and Anti-VEGF Bi-Specific Monoclonal Antibody, Part I) or Bevacizumab (Anti-VEGF Monoclonal Antibody, Part II) in Patients With Metastatic Solid Tumours

Summary:

This open-label, two-part study is designed to assess the safety, PK, PD, and therapeutic activity of RO7009789 in combination with vanucizumab or bevacizumab in participants with metastatic solid tumours not amenable to standard treatment. Part I (dose escalation) is designed to establish the maximum tolerated dose (MTD) of RO7009789 in this combination. Part II (expansion) is intended to characterize the safety and tolerability of RO7009789 in combination with bevacizumab among indication-specific cohorts and to confirm the recommended dose.
