Dose Escalation Study of a PD1-LAG3 Bispecific Antibody in Patients With Advanced and/or Metastatic Solid Tumors

Phase 1
Active, not recruiting
Conditions
Metastatic Melanoma
Non-small Cell Lung Cancer
Solid Tumors
Esophageal Squamous Cell Carcinoma
Interventions
Registration Number
NCT04140500
Lead Sponsor
Hoffmann-La Roche
Brief Summary

This is a first-in-human, open-label, multicenter, Phase I multiple-ascending dose (MAD) study of RO7247669, an anti PD-1 (programmed death-1) and LAG-3 (Lymphocyte-activation gene 3) bispecific antibody, for participants with advanced and/or metastatic solid tumors. This study aims to establish the maximum tolerated dose (MTD) and/or define the recommended phase 2 dose (RP2D) based on the safety, tolerability, pharmacokinetic (PK) and/or pharmacodynamic (PD) profile of RO7247669, and to evaluate preliminary anti-tumor activity in participants with solid tumors. An expansion part of the study is planned to enroll tumor-specific cohorts to evaluate anti-tumor activity of the MTD and/or RP2D of RO7247669 and to confirm safety and tolerability in participants with selected tumor types.

Part B: Tumor Specific Expansion CohortsRO7247669Participants with selected solid tumor indications will receive RO7247669 at a dose derived from Part A until disease progression, unacceptable drug toxicity, or withdrawal of consent, for up to 24 months.
Part A: Single-Agent Dose EscalationRO7247669Participants will receive RO7247669 every 2 weeks (Q2W) or every 3 weeks (Q3W) up to the maximum tolerated dose (MTD) until disease progression, unacceptable drug toxicity, or withdrawal of consent, for up to 24 months.
