Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Treatment: Drugs - RO7293583
Treatment: Drugs - Tocilizumab
Treatment: Drugs - Obinutuzumab
Treatment: Drugs - Adalimumab

Experimental: Part I: Single Participant Cohorts (IV) - 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.

Experimental: Part II: Multiple Participant Cohorts (IV/SC) - 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.


Treatment: Drugs: RO7293583
RO7293583 will be administered at a dose and per schedule as specified for the respective cohort.

Treatment: Drugs: Tocilizumab
Tocilizumab will be administered as required for the management of severe cytokine release syndrome (CRS).

Treatment: Drugs: Obinutuzumab
If implemented, it will be given either on D-7 or D-7 and D-6.

Treatment: Drugs: Adalimumab
If implemented, it will be given as a single dose approximately 6 days prior to the first dose of RO7293583.

Summary
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.
