Phase 2 Trial.
No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
This record has not been graded across any dimension yet. Treat the label above as provisional and read the source.
What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT04273061). This is a study registration, not published results. Lead sponsor: British Columbia Cancer Agency. Recruitment status: RECRUITING. Phase: PHASE2. Study type: INTERVENTIONAL. Enrollment: 50 participants (ESTIMATED). Conditions: Breast Cancer, Lung Cancer, Gastrointestinal Cancer, Genitourinary Cancer, Gynecologic Cancer, Sarcoma, Unknown Primary Tumors, Head and Neck Cancer, Skin Cancer. Interventions: DRUG: Atezolizumab. Primary outcome measures: Overall response rate (ORR) for the study cohort, as defined by RECIST 1.1 , 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.. Brief 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 50 participants. Participants are assigned to one of 3 cohorts based on their primary tumour type: gastrointestinal (GI), sarcoma, and 'other' cancer types. Participants in all cohorts will receive the same dose of atezolizumab (1200 mg every 3 weeks). Participants continue on treatment until they no longer may benefit from the treatment or they decide to stop treatment.
