Eligibility Criteria
Inclusion Criteria
- •Unresectable and/or metastatic HLA-G-positive solid tumors, for which standard therapy does not exist, or has proven to be ineffective or intolerable
- •Confirmed HLA-G tumor expression.
- •Radiologically measurable disease according to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1
- •Life expectancy of at least 12 weeks
- •Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
- •Adequate hematological, liver, renal and pulmonary function
- •Willingness to abide by protocol defined contraceptive requirements for the duration of the study.
Exclusion Criteria
- •History or clinical evidence of Central Nervous System (CNS) metastases unless protocol specified criteria are met
- •Leptomeningeal metastases
- •Rapid disease progression including lesions that are a threat to vital organs or non-irradiated lesions 2cm or larger at critical sites where tumor swelling may pose a risk to critical anatomical structures
- •Participants with another invasive malignancy in the last 2 years unless protocol specified criteria are met
- •Uncontrolled hypertension
- •Active interstitial lung disease (ILD), pneumonitis or a history of ILD/pneumonitis requiring treatment with steroids, history of idiopathic pulmonary fibrosis, organizing pneumonia, drug-induced pneumonitis, or idiopathic pneumonitis, or evidence of active pneumonitis on screening chest Computed Tomography (CT) scan
- •Participants with central cavitation or tumor(s) shown to be invading or abutting major blood vessels by imaging or the Investigator determines the tumor(s) is likely to invade major blood vessels and cause fatal bleeding
- •Participants with pulmonary military metastatic pattern or pulmonary lymphangitic carcinomatosis
- •History of pulmonary embolism within 3 months prior to study entry
- •Significant cardiovascular disease
Arms & Interventions
Part I Single Participant Cohort RO7515629 Dose Escalation
Participants will receive a fixed dose of RO7515629 intravenously as a single agent on cycle 0 day -7 and 7 days later on cycle 1 day 1 followed by every three-week dosing frequency. Treatment may continue for up to 12 months maximum or until progression, loss of clinical benefit, intolerable toxicity, withdrawal from study treatment or death.
Intervention: RO7515629
Part I Single Participant Cohort RO7515629 Dose Escalation
Participants will receive a fixed dose of RO7515629 intravenously as a single agent on cycle 0 day -7 and 7 days later on cycle 1 day 1 followed by every three-week dosing frequency. Treatment may continue for up to 12 months maximum or until progression, loss of clinical benefit, intolerable toxicity, withdrawal from study treatment or death.
Intervention: tocilizumab
Part II Multiple Participant Cohort RO7515629 Dose Escalation
Participants will receive RO7515629 intravenously, as a single agent on cycle 0 day -7 and 7 days later on cycle 1 day 1 followed by every three-week dosing frequency. In case of toxicity, step up dosing (single or double) may be implemented. Treatment may continue for up to 12 months maximum or until progression, loss of clinical benefit, intolerable toxicity, withdrawal from study treatment or death.
Intervention: RO7515629
Part II Multiple Participant Cohort RO7515629 Dose Escalation
Participants will receive RO7515629 intravenously, as a single agent on cycle 0 day -7 and 7 days later on cycle 1 day 1 followed by every three-week dosing frequency. In case of toxicity, step up dosing (single or double) may be implemented. Treatment may continue for up to 12 months maximum or until progression, loss of clinical benefit, intolerable toxicity, withdrawal from study treatment or death.
Intervention: tocilizumab
Part III Multiple Participant Cohort RO7515629 Dose Expansion
Participants with selected solid tumors will receive a selected dose of RO7515629 intravenously as a single agent based on the recommended dose sequence for expansion (RDE) and dosing regimen selected from Part I and Part II. Treatment may continue for up to 12 months maximum or until progression, loss of clinical benefit, intolerable toxicity, withdrawal from study treatment or death.
Intervention: RO7515629
Part III Multiple Participant Cohort RO7515629 Dose Expansion
Participants with selected solid tumors will receive a selected dose of RO7515629 intravenously as a single agent based on the recommended dose sequence for expansion (RDE) and dosing regimen selected from Part I and Part II. Treatment may continue for up to 12 months maximum or until progression, loss of clinical benefit, intolerable toxicity, withdrawal from study treatment or death.
