An Extension Study in Participants Previously Enrolled in a Genentech and/or F. Hoffmann-La Roche Ltd Sponsored Atezolizumab Study (IMbrella C)

July 2, 2026 updated by: Hoffmann-La Roche

An Open-Label, Multicenter Extension Study in Participants Previously Enrolled in a Genentech and/or F. Hoffmann-La Roche Ltd Sponsored Atezolizumab Study (IMbrella C)

This is an open-label, multicenter, non-randomized extension study. Participants receiving atezolizumab monotherapy or atezolizumab combined with other agent(s) or comparator agent(s) in a Genentech or Roche-sponsored study (the parent study), who are eligible to continue treatment and do not have access to the study treatment locally, continue to receive study treatment in this extension study.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

  • Eligible for continuing the comparator agent(s) in a Genentech- or Roche-sponsored study as per the parent study protocol, with no access to commercially available comparator agent
  • First dose of study treatment in this extension study will be received within 7 days of the treatment interruption window allowed by the parent study
  • Continue to benefit from atezolizumab-based study treatment or from the comparator at the time of rollover from the parent study as assessed by the investigator
