Brief Summary:

This study is evaluating the safety and tolerability of neoadjuvant stereotactic body radiation therapy (SBRT) with atezolizumab and bevacizumab for treating resectable hepatocellular carcinoma.

This study involves the following study interventions:

  • Atezolizumab
  • Bevacizumab
  • Stereotactic Beam Radiation Therapy (SBRT)
  • Surgery

Condition or disease Intervention/treatment Phase
Hepatocellular Carcinoma Resectable Hepatocellular Carcinoma Drug: Atezolizumab Drug: Bevacizumab Radiation: Stereotactic Beam Radiation Therapy (SBRT) Early Phase 1

Detailed Description:

This is a single-center, open-label, single-arm pilot study designed to evaluate the safety and tolerability of neoadjuvant radiation therapy plus atezolizumab and bevacizumab in patients with treatment-naïve resectable hepatocellular carcinoma.

This research study is a Pilot Study, which is the first-time investigators are examining this intervention of neoadjuvant radiation therapy plus atezolizumab and bevacizumab.

The U.S. Food and Drug Administration (FDA) has not approved atezolizumab, bevacizumab, stereotactic body radiation therapy (SBRT) for resectable hepatocellular carcinoma but they have been approved for other uses. Surgery is an accepted and standard treatment option for resectable hepatocellular carcinoma

The study interventions (atezolizumab bevacizumab, and SBRT) are thought to increase the immune system's (the system in the body that fights against disease) response to cancer cells. These interventions may increase the immune system's response by helping the T cells (an immune cell that identifies and attacks infected cells) recognize and find cancer cells in the body. By increasing the system's response, it is believed the chances of recurrence of resectable hepatocellular carcinoma will be less than when only standard of care surgery is used.

The research study procedures include screening for eligibility and study treatment, including evaluations and follow up visits.

Participants will receive study treatment for as long as they and their doctor believe they are benefitting from the study interventions and will be followed for 5 years or until participants withdraw their consent to be contacted.

It is expected that about 20 people will take part in this research study

Patients with eczema, psoriasis,lichen simplex chronicus, or vitiligo with dermatologic manifestations (e.g. patients with psoriatic arthritis are exluded) are eligible for the study provided that all of the following conditions are met:

    • Rash must cover <10% of body surface area
    • Disease is well-controlled at baseline and requires only low-potency topical corticosteroids.
    • No occurrence or acute exacerbations of the underlying condition requiring psoralen plus ultraviolet A radiation, methotrexate, retinoids, biologic agents, oral calcineurin inhibitors, or high-potency or oral corticosteroids within the previous 12 months.
  • History of idiopathic pulmonary fibrosis, organizing pneumonia (e.g. bronchiolitis obliterans), drug-induced pneumonitis, or idiopathic pneumonitis, or evidence of active pneumonitis on screen chest computed tomography (CT) scan.
  • Active tuberculosis (TB) as documented by a positive purified protein derivative (PPD) skin test or TB blood test and confirmed by a positive chest radiograph within 3 months prior to initiation of study treatment. Patients with a positive PPD skin test or TB blood test followed by a negative chest radiograph may be eligible for the study.
  • Significant cardiovascular disease (such as New York Heart Association Class II or greater cardiac disease, myocardial infarction, or cerebrovascular accident) within 3 months prior to initiation of study treatment, unstable arrhythmia, or unstable angina.
  • Major surgical procedure, other than for diagnosis, within 4 weeks prior to initiation of study treatment, or anticipation of need for a major surgical procedure during the study.
  • History of malignancy other than HCC within 5 years prior to screening, with the exception of malignancies with a negligible risk of metastasis or death (e.g., 5-year OS rate >90%), such as adequately treated carcinoma in situ of the cervix, non-melanoma skin carcinoma, localized prostate cancer, ductal carcinoma in situ, or Stage I uterine cancer.
  • Severe infection within 4 weeks prior to initiation of study treatment, including, but not limited to, hospitalization for complications of infection, bacteremia, or severe pneumonia. Treatment with therapeutic oral or IV antibiotics within 2 weeks prior to initiation of study treatment. Patients receiving prophylactic antibiotics (e.g., to prevent a urinary tract infection or chronic obstructive pulmonary disease exacerbation) are eligible for the study.
  • Any other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding that contraindicates the use of an investigational drug, may affect the interpretation of the results, or may render the patient at high risk from treatment complications.
  • Prior allogeneic stem cell or solid organ transplantation or on the wait list for liver transplantation.
  • Pregnancy or breastfeeding, or intending to become pregnant during the study. Women of childbearing potential must have a negative serum pregnancy test result within 14 days prior to initiation of study treatment. The rationale for this exclusion is the unknown toxicities of immune checkpoint inhibitors on developing fetuses and the known placental risk conferred by treatment with vascular endothelial growth factor inhibitors (such as bevacizumab).
  • Treatment with a live, attenuated vaccine within 4 weeks prior to initiation of study treatment, or anticipation of need for such a vaccine during atezolizumab treatment or within 5 months after the final dose of atezolizumab.
  • History of severe allergic anaphylactic reactions to chimeric or humanized antibodies or fusion proteins.
  • Known hypersensitivity to Chinese hamster ovary cell products or recombinant human antibodies.
  • Known allergy or hypersensitivity to any of the study drugs or any of their excipients.
  • Treatment with systemic immunostimulatory agents (including, but not limited to, interferon and interleukin 2 [IL-2]) within 4 weeks or 5 drug-elimination half-lives (whichever is longer) prior to initiation of study treatment.
  • Treatment with systemic immunosuppressive medication (including, but not limited to, corticosteroids, cyclophosphamide, azathioprine, methotrexate, thalidomide, and anti-TNF-alpha agents) within 2 weeks prior to initiation of study treatment, or anticipation of need for systemic immunosuppressive medication during study treatment, with the following exceptions:

    • Patients who received acute, low-dose systemic immunosuppressant medication or a one-time pulse dose of systemic immunosuppressant medication (e.g., 48 hours of corticosteroids for a contrast allergy) are eligible for the study after Medical Monitor confirmation has been obtained.
    • Patients who received mineralocorticoids (e.g., fludrocortisone), corticosteroids for chronic obstructive pulmonary disease (COPD) or asthma, or low-dose corticosteroids for orthostatic hypotension or adrenal insufficiency are eligible for the study.
  • Since this study aims to enroll only resectable (with curative intent) hepatocellular carcinoma subjects, patients with brain (or other sites of distant) metastases are excluded.
  • Participants with uncontrolled intercurrent illness.
  • Participants with psychiatric illness/social situations that would limit compliance with study requirements.
