Brief Summary

This first-in-human study consists of three parts. The primary purpose of Part 1 is to characterize the safety and tolerability of RO6874813 in participants with locally advanced and/or metastatic solid tumors whose disease has progressed despite standard therapy or for whom no standard therapy exists. In addition, the maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D) will be determined. In Part 2 the safety and tolerability of RO6874813 will continue to be characterized in participants with locally advanced and/or metastatic solid tumors known to be fibroblast activation protein-alpha positive (FAP+). In addition, treatment-induced efficacy of RO6874813 will be assessed by functional imaging and paired tumor biopsies. The primary purpose of Part 3 is to demonstrate anti-tumor activity of RO6874813 in participants with recurrent or metastatic FAP+ sarcomas.

Study Arms (3)

Part 1: Dose Escalation

EXPERIMENTAL

All participants will be given RO6874813 as a single low dose of 0.5 milligrams per kilogram (mg/kg) via intravenous (IV) infusion in a 7-day pharmacokinetic (PK) run-in period (Cycle 0). This is followed by dose escalation (Cycle 1) for which participants will receive escalating doses of RO6874813 (starting dose = 1 mg/kg) via IV infusion every week (qw) or every 2 weeks (Q2W) for 28 to 42 days to determine the maximum tolerated dose (MTD) and recommended Phase 2 dose (RP2D).

Biological: RO6874813

Part 2: Tumor Biopsy and Imaging

EXPERIMENTAL

The first 15 participants with fibroblast activation protein-alpha positive (FAP+) tumors will be treated at the RP2D and dosing schedule as determined in Part 1, and will undergo paired tumor biopsies for biomarker assessments. Up to 5 participants with FAP+ tumors will undergo baseline and on-treatment tumor biopsies for biomarker assessments at a dose below the RP2D. The dose for these participants can be escalated to RP2D after 4 weeks of treatment and upon completion of biomarker assessment.

Biological: RO6874813

Part 3: Preliminary Efficacy Assessment

EXPERIMENTAL

Participants with locally advanced or metastatic non-resectable FAP+ sarcoma will be treated with RO6874813 at the RP2D and as per schedule determined upon completion of Part 1. Participants continuing treatment with RO6874813 beyond 36 weeks will enter the extension phase of Part 3 and will be monitored for disease status and clinical safety per routine standard of care.

Biological: RO6874813

Interventions

RO6874813 BIOLOGICAL

RO6874813 will be administered at a single low dose of 0.5 mg/kg via IV infusion in a 7- day PK run-in period (Cycle 0). Dose level for RO6874813 will be escalated to determine MTD and RP2D for RO6874813.
