Plain English summary of protocol
Background and study aims
This study will investigate the dose, safety, interaction with the body (pharmacokinetics), and anti-tumor activity of the novel drug RO6870810 in combination with a fixed dose of atezolizumab in patients with advanced ovarian cancer or triple negative breast cancer with no alternative treatment options, or refusal to undergo an alternative treatment.
Patients with advanced ovarian cancer or triple negative breast cancer have a significant need for new therapies to be developed. Encouraging results have been observed for the use of atezolizumab for solid tumours. Additionally, previous studies for RO6870810 and atezolizumab suggest that atezolizumab may be effective in advanced TNBC and OC and that RO6870810 may enhance the clinical effectiveness of atezolizumab therapy.
Who can participate?
Adults and senior patients with advanced ovarian cancer or triple negative breast cancer.
What does the study involve?
The participants in the study will be divided into four groups. Group 1 will be the Dose-Escalation (DE) group and Group 2 will be the Sequential Dose Group (which will involve an initial treatment period of RO6870810 alone, followed by RO6870810 in combination with atezolizumab). For Groups 1 and 2 RO6870810 will be injected below the skin (subcutaneous) once daily for the first 14 days of a 21-day cycle. For all groups Atezolizumab will be given via the vein (intravenously) at a fixed dose on the first day of each cycle, every 3 weeks. Treatment with the study drug may occur for up to 22 months.
Participants in Group 3 and Group 4 (Expansion group) will recieve the recommended dose of RO6870810, which will have been established in Group 1, administered in combination with atezolizumab.
For each participant, mandatory (archival tissue or fresh) tumor biopsies will be collected during the study.
What are the possible benefits and risks of participating?
Previous studies for RO6870810 and atezolizumab have shown potential for positive effects on patient outcomes in advanced ovarian cancer or triple negative breast cancer . Both RO6870810 and atezolizumab have been well-tolerated as treatment when not in combination.
The most common adverse events reported with RO6870810 include tiredness, decreased appetite, digestive disorders (nausea, vomiting, diarrhea, and constipation), blood toxicities (anemia, thrombocytopenia). The most commonly reported adverse events with single-agent atezolizumab include tiredness, decreased appetite, digestive disorders (nausea, diarrhea, and constipation), and cough. Based on previous experiences with RO6870810 and atezolizumab and their respective safety profiles, there is potential for some overlapping effects. Those include fatigue, decreased appetite, and gastrointestinal toxicities.
Taking into account both the anticipated activity of the combination and the effective measures in place to manage toxicities, it is believed that the overall risk-benefit assessment for this combination is favorable and justifies its exploration in patients for whom standard treatment options are limited.
