Study Details
Study Description
Brief Summary
To find out if adding pembrolizumab to standard of care chemotherapy drugs (cisplatin and gemcitabine) will improve long-term response of intrahepatic cholangiocarcinoma after surgery, compared to treatment with surgery and standard chemotherapy alone.

Detailed Description
Primary Objectives and Endpoints:
-
To evaluate RFS. RFS will be defined as time from curative-intent surgery to disease recurrence. Median, 9-month, and 12-month RFS rates will be measured.
-
To evaluate the rate of major pathologic response. Pathologic response will be assessed both by determining the percentage of the bulk tumor made up of viable cancer cells, with < 10% signifying a major pathologic response, and by evaluating indicators of immune-mediated pathologic response which incorporate elements of tumor necrosis and fibroinflammatory stroma.
Primary Endpoints: RFS rate, major pathologic response rate
Secondary Objectives and Endpoints:
Objectives: To assess safety and other markers of efficacy, including objective response rate (ORR) and overall survival (OS).
Secondary Endpoints:
-
To evaluate the safety and efficacy of pembrolizumab in combination with gemcitabine and cisplatin
-
Safety profile per CTCAE v5.0, including term, incidence, severity, and duration of AEs
-
Objective response rate (ORR) by RECIST 1.1 criteria
-
12- and 24-month overall survival (OS) by RECIST 1.1 criteria
-
Median progression free survival (PFS) and median overall survival (OS) according to RECIST v1.1
Exploratory Objectives and Endpoints:
-
Correlative studies will be performed to assess the immunologic response to neoadjuvant pembrolizumab with gemcitabine and cisplatin including but not limited to blood and tissue-based biomarkers, gene alterations, immunologic markers and pharmacodynamic markers from study treatment.
-
To assess and correlate gut microbiome diversity, composition, structure, and functional characteristics pre- and post-NAT.
-
To assess the biliary microbiome diversity, composition and functional characteristics (if bile is able to be collected at the time of surgery), and to compare the biliary microbiome to pre- and post-NAT gut microbiome, as well as to clinicopathologic outcomes.
-
To evaluate the effects of pembrolizumab on pharmacodynamic markers: ctDNA, tissue biopsies, and/or blood to assess biomarkers. include, but are not limited to, circulating tumor DNA and exosome analyses, gene expression studies, reverse phase protein arrays (RPPA, and Nanostring and/or RNA-exome to assess mRNA expression.

Note: Participants with hyperbilirubinemia due to non-hepatic cause (e.g., hemolysis, hematoma) may be enrolled following discussion and agreement with the principle investigator

-
For patients with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated.
-
Patients with a history of hepatitis C virus (HCV) infection must have been treated and cured. For patients with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load.
-
Willing and able to participate in the trial and comply with all trial requirements.
-
Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational agent may be included after consultation with the medical monitor.
-
The effects of pembrolizumab in combination with gemcitabine and cisplatin on the developing human fetus are unknown. For this reason and because gemcitabine and cisplatin used in this trial are known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. (Refer to Pregnancy Assessment Policy MD Anderson Institutional Policy
CLN1114). This includes all female patients, between the onset of menses (as early
as 8 years of age) and 55 years unless the patient presents with an applicable exclusionary factor which may be one of the following:
-
Postmenopausal (no menses in greater than or equal to 12 consecutive months).
-
History of hysterectomy or bilateral salpingo-oophorectomy.
-
Ovarian failure (Follicle Stimulating Hormone and Estradiol in menopausal range, who have received Whole Pelvic Radiation Therapy).
-
History of bilateral tubal ligation or another surgical sterilization procedure.
-
Approved methods of birth control are as follows: Hormonal contraception (i.e. birth control pills, injection, implant, transdermal patch, vaginal ring), Intrauterine device (IUD), Tubal Ligation or hysterectomy, Subject/Partner post vasectomy, Implantable or injectable contraceptives, and condoms plus spermicide. Not engaging in sexual activity for the total duration of the trial and the drug washout period is an acceptable practice; however periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of birth control. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately.
-
Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study for the duration of study participation, and 4 months after completion of treatment administration.
-
Ability to understand and the willingness to sign a written informed consent document.
-
English and non-English-speaking patients.
-
Patients with HIV on effective anti-retroviral therapy with undetectable viral load and CD4 count > 100 cells/µL within 6 months are eligible for this trial.
