研究概览
简要总结
The purpose of this research is to evaluate whether adding histotripsy to maintenance durvalumab increases immune response and to assess the safety of this combination for participants with advanced intrahepatic cholangiocarcinoma (iCCA). Histotripsy is a non-invasive, non-thermal treatment that uses focused ultrasound energy to destroy tumor tissue. 12 people will be enrolled in this study.
详细描述
The primary objective of this pilot phase II study is to evaluate preliminary efficacy of increased immune system activation and safety of combined histotripsy and maintenance durvalumab therapy.
The secondary objectives are to evaluate additional efficacy signal and safety of the addition of histotripsy along with continued maintenance durvalumab therapy.
Exploratory objectives include evaluation for off-target effects on iCCA tumors not targeted for histotripsy treatment and evaluation of peripheral blood samples for assessment of circulating immune biomarkers and circulating tumor DNA (ctDNA).

- •Participant meets the following functional criteria, ≤7 days prior to the planned histotripsy procedure date
- •Liver function: Alanine transaminase (ALT) and Aspartate transaminase (AST) <2.5x upper limit of normal (ULN) and/or bilirubin <2.5 ULN.
- •Renal function: serum creatinine <2x ULN.
- •Hematologic function: Absolute neutrophil count >1,000/uL and platelet >50,000/uL, hemoglobin >8.0 g/dL.
- •Participant has an International Normalized Ratio (INR) score of <3.0, ≤7 days prior to the planned histotripsy procedure date.
- •Persons of childbearing potential must have a negative pregnancy test (serum or urine) within 7 days prior to registration.
- •Females of childbearing potential who are sexually active with a male able to father a child must be willing to abstain from heterosexual vaginal intercourse or use an effective method(s) of contraception from the time of informed consent, during the study and for up to 14 months after the last dose of study drug(s). 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.
排除标准
- •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.
研究组 & 干预措施
Participants with advanced iCCA
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.

Number of Participants with Increase in Adaptive Immune System Response following histotripsy
时间窗: data collected cycle 1 day 3 (C1D3) and cycle 1 day 22 (C1D22) (up to about 30 days with allowable procedural windows)
Increased adaptive immune system response following histotripsy in addition to ongoing maintenance durvalumab therapy will be interpreted as T cell infiltration, downregulation of myelosuppressive cell types, and upregulation of IFN-γ. This will be completed on the biopsy tissue (pre histotripsy in comparison to post histotripsy).
