About

This study is being done to look at how effective the drug, atezolizumab, with or without the drug bevacizumab, is for people with inoperable liver cancer or non-small lung cancer that has spread to the liver. This will be done by looking at the duration of time from starting the study drug(s) until the cancer worsens in study participants. This study will collect blood and tumor tissue samples from participants to look at changes to their tumor(s) before and after receiving atezolizumab and/or bevacizumab.

Full description

Participants with liver cancer will be assigned to Arm A and receive atezolizumab and bevacizumab. Participants with non-small cell lung cancer will be randomized into one of the following arms: Arm B: Atezolizumab and bevacizumab Arm C: Atezolizumab alone Participants randomized to Arm C whose disease worsens may be able to cross over to Arm B and receive atezolizumab and bevacizumab together.

Inclusion criteria

  • Be willing and able to provide written informed consent.
  • Be ≥ 18 years of age on day of signing informed consent.
  • Have histologically or cytologically confirmed diagnosis of inoperable hepatocellular carcinoma (HCC) or non-squamous non-small cell lung cancer (NSCLC) with liver metastases with at least one measurable lesion.
  • NSCLC patients who were previously treated with chemotherapy or treatment naïve patients with a programmed death ligand-1 (PD-L1) tumor proportion score ≥50% or tumor cell score 3/immune cell score 3 are included.

  • Be willing to provide tumor tissue from a core biopsy of a tumor lesion (archival not acceptable). The subject must have a site of disease amenable to biopsy, and be a candidate for tumor biopsy. In addition, the subject must be willing to give blood for correlative studies, and have no contraindications to this.
  • Have a performance status of 0 or 1 on the Eastern Cooperative Oncology Group (ECOG) Performance Scale.
  • Have recovered (to ≤ grade 1) from prior toxicities related to previous treatments at the time of study enrollment, with the exception of alopecia or skin depigmentation.
  • Be tested for Hepatitis B-virus surface antigen (HBsAg) status. Patients may be included in the study if they have adequately controlled hepatitis B
  • Patients must be tested for hepatitis C virus (HCV) status. Subjects with chronic infection by HCV who are untreated are allowed on study. In addition, subjects with successful HCV treatment are allowed as long as 4 weeks have passed between completion of HCV therapy and start of study treatment.

  • Agrees to use use highly effective contraceptive methods, not donate egg or sperm, during study participation, and for at least 6 months after the last dose of study medications.
  • Life expectancy expected to be 3 months or greater.

Exclusion criteria

  • Has received stereotactic radiotherapy within 4 weeks of trial commencement. For chemotherapy, tyrosine kinase inhibitors and palliative-dose radiotherapy, a 2 week washout is required.

  • Inadequately controlled hypertension (defined as systolic blood pressure [BP] > 150 mmHg and/or diastolic blood pressure > 100 mmHg), based on an average of ≥ 3 BP readings on ≥ 2 sessions. Anti-hypertensive therapy to achieve these parameters is allowed.

  • Significant vascular disease (eg. aortic aneurysm requiring surgical repair or recent peripheral arterial thrombosis) within 6 months prior to randomization
  • History of Grade ≥ 4 venous thromboembolism.
  • History of Grade ≥ 2 hemoptysis (defined as ≥ 2.5 mL of bright red blood per episode) within 1 month prior to screening for HCC and within 3 months for NSCLC.
  • History or evidence of bleeding diathesis or significant coagulopathy at risk of bleeding (ie. In the absence of therapeutic anticoagulation)
  • Surgical procedure (including open biopsy, surgical resection, wound revision, or any other major surgery involving entry into a body cavity) or significant traumatic injury within 28 days prior to initiation of study treatment and wounds are fully healed, or anticipation of need for major surgical procedure during the course of the study.
  • Serious, non-healing or dehiscing wound, active ulcer, or untreated bone fracture.
  • Evidence of tumor invading or abutting major blood vessels.
  • History of abdominal fistula, gastrointestinal (GI) perforation, intra-abdominal abscess, or active GI bleeding within 6 months prior to randomization.
  • Serious, non-healing wound, active ulcer, or untreated bone fracture
  • Current or recent (< 10 days prior to initiation of study treatment) use of aspirin (> 325 mg/day) or treatment with dipyramidole, ticlopidine, clopidogrel (> 75 mg/day) and cilostazol.
  • Current or recent (< 10 days prior to initiation of study treatment) use of full-dose oral or parenteral anticoagulants or thrombolytic agents for therapeutic purpose
