Males able to father a child must be willing to abstain from heterosexual vaginal intercourse or to use an effective method(s) of contraception from initiation of treatment, during the study and for up to 11 months after the last dose of study drug(s).
  • Ability of the participant to understand and comply with study procedures for the entire length of the study, as determined by the enrolling physician or protocol designee.

You cannot join if

  • Participant is pregnant or planning to become pregnant or nursing (lactating) during the trial period.
  • Participant is enrolled in another investigational trial and/or is taking investigational medication or treated with an investigational device ≤30-days prior to planned histotripsy procedure date.
  • In the Investigator's opinion, the subject has co-morbid disease(s) or condition(s) that would cause undue risk and preclude safe histotripsy treatment, including but not limited to interstitial lung disease, including history of interstitial lung disease or non-infectious pneumonitis.
  • Active autoimmune disease that has required systemic treatment in the past 2 years (i.e., with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment. .
  • Participant has major surgical procedure or significant traumatic injury ≤2 weeks prior to the planned treatment or not fully recovered (CTCAE grade 1 or better) from side effects/complications of such procedure or trauma.
  • Participant has not recovered to Common Terminology Criteria for Adverse Events (CTCAE) grade 1 or better from any adverse effects (exceptions for alopecia, grade 2 neuropathy, grade 2 hypothyroidism, grade 2 hypoadrenalism) related to previous anti-cancer therapy. Please refer to inclusion criteria for lab-based enrollment parameters.
  • Participant has a history of bleeding disorders (e.g. von Willebrand disease) or subject is suspected to have a bleeding disorder.
  • Participant has uncorrectable coagulopathy.
  • In the opinion of the Investigator, histotripsy is not a treatment option for the subject.
  • Participant has a concurrent condition that, in the investigator's opinion, could jeopardize the safety of the subject or compliance with the protocol.
  • Participants' tumor(s) is not targetable per discretion of radiologist.
  • Participant has a known sensitivity to contrast media and cannot be adequately pre-medicated.
  • Participants' Target Tumor(s) has/have had prior locoregional therapy (e.g. ablation, embolization, radiation).
  • History of solid organ or allogeneic bone marrow transplantation.
  • Patients with a prior or concurrent malignancy whose natural history or treatment has the potential to interfere with the safety or efficacy assessment of the investigational regimen are not eligible for this trial.
  • Significant dementia or other mental condition that precludes the participant's ability to consent to the study.
  • Untreated central nervous system (CNS) metastasis. Screening of asymptomatic patients for CNS metastasis is not required for enrollment.
  • Live vaccine administration within 28 days of planned initial dose of durvalumab.

The treatment

How it is intended to work

This is how the treatment is meant to work. Whether it helps, and how safe it is, is what this trial is testing.

durvalumab. A monoclonal antibody directed against B7H1 (B7 homolog 1; programmed cell death ligand 1) with potential immunostimulating activity. Upon intravenous administration, durvalumab binds to the cell surface antigen B7H1, thereby blocking B7H1 signaling. This may activate the immune system to exert a cytotoxic T-lymphocyte (CTL) response against B7H1-expressing tumor cells. B7H1, a member of the B7 protein superfamily and a negative regulator of cytokine synthesis, is overexpressed on certain tumor cell types. NCI Drug Dictionary

Treatments listed in the registry

  • Histotripsy (Device): Histotripsy will be performed using the Edison® System (HistoSonics, Inc.), which is FDA cleared for destruction of liver tissue using non thermal focused ultrasound. Performed on Cycle 1 Day 8 (C1D8) to treat the Target Tumor.
  • Durvalumab (Drug): Durvalumab is an immunotherapy drug and will be administered on day 1 of each 28-day cycle as per local standards. Dosing of maintenance durvalumab is 1500mg IV per FDA labeling with administration performed over 60 minutes as per standard clinical practice.
  • Biopsy (Procedure): Two research biopsies are planned for cycle 1 day 3 and cycle 1 day 22, before and after histotripsy.

The study

Treatment groups

Na · Single Group · masking: None

Participants with advanced iCCA (Experimental)

3 research specific visits; pre-histotripsy treatment (C1D3), 14-day post histotripsy follow-up with biopsy (C1D22), and 30-day post histotripsy treatment adverse events assessment. The remaining visits, including the histotripsy treatment and durvalumab infusions, are a part of the study protocol but are part of the patient's ongoing medical care. Participants followed until progression up to 5 years.

What it involves

Procedures

  • blood samples: Part of the study plan

Goals

What the study measures

Main goals

  • Number of Participants with Increase in Adaptive Immune System Response following histotripsy (data collected cycle 1 day 3 (C1D3) and cycle 1 day 22 (C1D22) (up to about 30 days with allowable procedural windows))
  • Percent of Participants Experiencing Immune-mediated Adverse Events within 30 days of histotrispy (data collected up to day 38 (30 days post-histotripsy))

Other goals

  • Overall Survival (OS)
  • Treatment Efficacy
  • Hepatic toxicity profile of immunotherapy checkpoint with histotripsy reported as Incidence of Dose Limiting Toxicities per Protocol
