- Brief Summary
This is a first-in-human, multi-center clinical study to determine the safety, Maximum Tolerated Dose (MTD) and/or Optimal Biological Dose (OBD) as well as the optimal schedule for intravenous (IV) and/or subcutaneous (SC) administrations of RO7293583 with or without obinutuzumab pretreatment, in participants with unresectable metastatic TYRP1-positive melanomas who have progressed on standard of care (SOC) treatment, are intolerant to SOC, or are non-amenable to SOC. This study will include an initial single participant dose-escalation part one followed by a multiple participant dose-escalation part two with the possibility of expansion.

Group Intervention Description Part I: Single Participant Cohorts (IV) RO7293583 Part I is a dose escalation in single participant cohorts. RO7293583 will be administered intravenously (IV) every three weeks (Q3W). The starting dose will be 0.045mg and the maximum dose explored will be 1.5mg. Part II: Multiple Participant Cohorts (IV/SC) RO7293583 Multiple ascending dose-escalation of RO7293583 in multiple participant cohorts: The starting-dose for the initiation of the IV dose-escalation will be determined by Part I and RO7293583 will be administered IV or SC every 3 weeks. Dose-escalation will be undertaken based on safety until determination of the MTD or the highest safe dose if MTD is not reached. Fractionated, step up or subcutaneous dosing may be implemented. The maximum dose explored will be 600mg IV and 160mg SC. Part I: Single Participant Cohorts (IV) Tocilizumab Part I is a dose escalation in single participant cohorts. RO7293583 will be administered intravenously (IV) every three weeks (Q3W). The starting dose will be 0.045mg and the maximum dose explored will be 1.5mg. Part II: Multiple Participant Cohorts (IV/SC) Tocilizumab Multiple ascending dose-escalation of RO7293583 in multiple participant cohorts: The starting-dose for the initiation of the IV dose-escalation will be determined by Part I and RO7293583 will be administered IV or SC every 3 weeks. Dose-escalation will be undertaken based on safety until determination of the MTD or the highest safe dose if MTD is not reached. Fractionated, step up or subcutaneous dosing may be implemented. The maximum dose explored will be 600mg IV and 160mg SC. Part II: Multiple Participant Cohorts (IV/SC) Obinutuzumab Multiple ascending dose-escalation of RO7293583 in multiple participant cohorts: The starting-dose for the initiation of the IV dose-escalation will be determined by Part I and RO7293583 will be administered IV or SC every 3 weeks.

- Primary Outcome Measures
Name Time Method Percentage of Participants With Dose-Limiting Toxicities (DLTs) From Day 1 of Cycle 1 up to Day 1 of Cycle 3 (each cycle is 21 days) Dose-Limiting Toxicities (DLTs) were reported according to the National Cancer Institute Common Terminology Criteria for Adverse Events, Version 5.0 (NCI CTCAE v5.0), except for Cytokine release syndrome (CRS), which will be graded based on the American Society for Transplantation and Cellular Therapy (ASTCT) criteria.
Percentage of Participants with Adverse Events (AEs) Baseline up to 60 days after last RO7293583 treatment (up to 14 months) An adverse event (AE) is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product.
- Secondary Outcome Measures
Name Time Method Clearance (CL) or Apparent Clearance (CL/F) of RO7293583 Up to 14 months Overall Survival (OS) Baseline up to 24 months. OS is defined as the time from Cycle 1, Day 1 to death from any cause.
Volume of Distribution at Steady State (Vss) of RO7293583 Up to 14 months Area Under the Curve (AUC) of RO7293583 Up to 14 months Percentage of Participants with Anti-Drug Antibodies (ADAs) to RO7293583 From baseline until 60 days after last RO7293583 dose (up to 14 months). Change from Baseline in RO7293583 ADA Titer From baseline until 60 days after last RO7293583 dose (up to 14 months). Objective Response Rate (ORR) Baseline up to 13 months ORR is defined as the percentage of participants with confirmed objective response (OR). Confirmed OR is defined as complete response (CR) or partial response (PR) on two consecutive occasions ≥ 4 weeks apart, as determined by the investigator according to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. CR is defined as disappearance of all target lesions. PR is defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum of diameters.
Maximum Concentration (Cmax) of RO7293583 Up to 14 months Time of Maximum Concentration (Tmax) of RO7293583 Up to 14 months Minimum Concentration (Cmin) of RO7293583 Up to 14 months SC Bioavailability (F) of RO7293583 Up to 14 months Disease Control Rate (DCR) Baseline up to 13 months DCR is defined as the percentage of participants with CR, PR, or stable disease (SD). Per RECIST v1.1, CR is defined as disappearance of all target lesions. PR is defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum of diameters. SD is defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for disease progression, taking as reference the smallest sum on study. Disease progression is defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study including baseline, or the appearance of one or more new lesions.
Duration of Response (DOR) Baseline up to 13 months DOR is defined as the time from the first occurrence of documented OR to disease progression, as determined by the investigator according to RECIST v1.1, or death from any cause, whichever occurs first. Disease progression is defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study including baseline; or the appearance of one or more new lesions.
Progression-Free Survival (PFS) Baseline up to 24 months. PFS is defined as the time from Cycle 1, Day 1 to the first occurrence of disease progression, as determined by the investigator according to RECIST v1.1, or death from any cause, whichever occurs first. Disease progression is defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study including baseline; or the appearance of one or more new lesions.
