Investigating the Effects of Atezolizumab in People Whose Tumour DNA or RNA Indicates Possible Sensitivity
Canada200 participantsStarted 2020-06-17
Plain-language summary
This study will investigate the effects of atezolizumab on select cancer types in people whose analysis of tumour DNA and RNA indicates they may be sensitive to atezolizumab. This study aims to determine if the information from the cancer genome analysis corresponds with the effects of atezolizumab on individuals and their cancer.
This is a Phase 2 study, which is undertaken after preliminary safety testing on a drug is completed, and will involve approximately 200 participants. Participants are assigned to one of 8 cohorts based on their primary tumour type: breast, lung, gastrointestinal (GI), primary unknown, genitourinary (GU), sarcoma, gynecological, and 'other' cancer types. Participants in all cohorts will receive the same dose of atezolizumab (1200 mg every 3 weeks). In the first stage for each cohort, 8 participants will be enrolled and if no participants respond to treatment, enrollment to that cohort will be closed. If 1 or more participants respond to treatment, up to 16 additional participants will be enrolled to that cohort. Participants continue on treatment until they no longer may benefit from the treatment or they decide to stop treatment.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
. Platelet count ≥ 100,000/µL without transfusion (without transfusion within 2 weeks of laboratory test used to determine eligibility).
. Hemoglobin ≥ 9.0 g/dL, participants may be transfused or receive erythropoietic treatment to meet this criterion.
. International normalized ratio (INR) or activated partial thromboplastin time (aPTT) ≤ 1.5 × Upper Limit of Normal (ULN). This applies only to participants who are not receiving therapeutic anticoagulation; participants receiving therapeutic anticoagulation must have an INR or aPTT within therapeutic limits for at least 1 week prior to enrolment.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Overall response rate (ORR) in each tumour-defined cohort, as defined by RECIST 1.1
Timeframe: From the date of the screening scan (within 28 days of first dose) until the date of confirmed progression, withdrawal, or date of death, whichever comes first, assessed up to 54 months.
. Aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) ≤ 2.5 × ULN with the following exceptions: i) Participants with documented liver metastases: AST and/or ALT ≤ 5 × ULN. ii) Participants with documented liver or bone metastases: ALP ≤ 5 × ULN.
. Participants with a history of autoimmune-related hypothyroidism on a stable dose of thyroid-replacement hormone may be eligible for this study.
. Participants with controlled Type I diabetes mellitus on a stable dose of insulin regimen are eligible for this study.
. Rash must cover less than 10% (ten percent) of body surface area (BSA).
. Disease is well controlled at baseline and only requiring low potency topical steroids.
. No acute exacerbations of underlying condition within the last 12 months requiring treatment with either psoralen plus ultraviolet radiation (PUVA), methotrexate, retinoids, biologic agents, oral calcineurin inhibitors or high potency or oral steroids.
. Positive hepatitis B surface antigen (HBsAg) test at screening; or
. Negative or positive hepatitis B surface antibody (HBsAb) test at screening accompanied by a positive total hepatitis B core antibody (HBcAb) test followed by a positive (per local laboratory definition) HBV DNA test.
