A Study to Evaluate the Effectiveness of M7824 Monotherapy in Locally Advanced or Metastatic Biliary Tract Cancer (Cholangiocarcinoma and Gallbladder Cancer)

Overview

About this study

The purpose of this study is to evaluate M7824 monotherapy in participants with advanced or metastatic biliary tract cancer (BTC) who failed or were intolerant to first-line (1L) chemotherapy.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria: 

  • Are ≥ 18 years of age at the time of signing the informed consent. In Japan, if a participant is at least 18 but < 20 years of age, written informed consent from his/her parent or guardian will be required in addition to the participant’s written consent.
  • Are participants with histologically or cytologically confirmed locally advanced or metastatic biliary tract cancer (BTC). 
  • Availability of tumor (primary or metastatic) archival material or fresh biopsies is mandatory. Fine needle aspirates, transductal aspirates, or cell blocks are not acceptable.  Endoscopic retrograde cholangiography or intraductal ultrasounds assisted biopsy is acceptable, needle or excisional biopsies, or resected tissue, are preferable. Tumor biopsies and tumor archival material must be suitable for biomarker assessment as described in the Laboratory Manual.
  • Participants with BTC must have failed or be intolerant to 1L systemic platinum-based chemotherapy administered for locally advanced or metastatic disease. Only one prior treatment line is allowed. Participants who received adjuvant platinum-based chemotherapy and had evidence of disease recurrence within 6 months of completion of the adjuvant treatment are also eligible. If recurrence occurs during or within 6 months after the adjuvant chemotherapy, adjuvant platinum-based chemotherapy is counted as 1L chemotherapy.
  • Disease must be measurable with at least 1 unidimensionally measurable lesion by RECIST 1.1 and verified independently by IRC..
  • Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) of 0 to 1 at study entry and Day 1 of treatment with M7824.
  • Life expectancy ≥ 12 weeks as judged by the Investigator.
  • Adequate hematological function defined by white blood cell (WBC) count ≥ 3 × 10^9/L with absolute neutrophil count ≥ 1.5 × 10^9/L, lymphocyte count ≥ 0.5 × 10^9/L, platelet count ≥ 75 × 10^9/L, and hemoglobin (Hgb) ≥ 9 g/dL.
  • Adequate hepatic function defined by a total bilirubin level ≤ 1.5 × upper limit of normal (ULN), an aspartate aminotransferase (AST) level ≤ 2.5 × ULN, and an alanine aminotransferase (ALT) level ≤ 2.5 × ULN. For participants with liver  involvement in their tumor, AST ≤ 5.0 × ULN and ALT ≤ 5.0 × ULN is acceptable:
    • Participants with biliary obstruction should have an adequate biliary drainage with no evidence of ongoing infection. Biliary duct obstruction should be relieved by internal endoscopic drainage/stenting at least 2 weeks prior to  dosing or by palliative bypass surgery or percutaneous drainage prior to study entry, and the participant should have no active or suspected infection. Participants fitted with a biliary stent should be clinically stable and free of signs of infection for ≥ 2 weeks prior to dosing;
    • Adequate coagulation function defined as prothrombin time (PT) or international normalized ratio (INR) ≤ 1.5 × ULN unless the participant is receiving anticoagulant therapy.
  • Albumin ≥ 3.0 g/dL.
  • Hepatitis B virus (HBV) deoxyribonucleic acid (DNA) positive participants must be treated and on a stable dose of antivirals (e.g., entecavir, tenofovir, or lamivudine; adefovir or interferon are not allowed) at study entry and with planned monitoring and management including baseline HBV DNA quantity according to appropriate labeling guidance.  Participants receiving active hepatitis C virus (HCV) therapy must be on a stable dose at study entry and with planned monitoring and management according to appropriate labeling guidance of an approved antiviral.
  • Adequate renal function defined by either creatinine ≤1.5 × ULN or an estimated creatinine clearance (CCr) > 40 mL/min according to the Cockcroft-Gault formula or by measure of CCr from 24-hour urine collection.
    • CCr (mL/min) = (140-age) × weight (kg)/(72 × serum Cr jaffe);
    • If female, × 0.85;
    • If Cr is measured by enzymatic method, add 0.2 and use as Crjaffe = 0.2 + Crenzyme.
  • Male participants are eligible to participate if they agree to the following during the intervention period and for at least 4 months after the last dose of study intervention:
    • Refrain from donating sperm PLUS; either
    • Abstain from intercourse with a female; OR
    • Use a male condom:
      • When having sexual intercourse with a woman of childbearing potential (WOCBP), who is not currently pregnant, and advise her to use a highly effective contraceptive method with a failure rate of < 1% per year, as described in Appendix 3, since a condom may break or leak;
      • When engaging in any activity that allows for exposure to ejaculate.
  • A female is eligible if she is not pregnant or breastfeeding, and at least one of the following conditions applies:
    • Not a WOCBP; OR
    • If a WOCBP, use a highly effective contraceptive method (i.e., with a failure rate of < 1% per year), preferably with low user dependency, as described in Appendix 3 for the following time periods:
      • Before the first dose of the study intervention(s), if using hormonal contraception:
        • Has completed at least one 4-week cycle of an oral contraception pill and either had or has begun her menses; OR
        • Has used a depot contraceptive or extended-cycle oral contraceptive for least 28 days and has a documented negative pregnancy test using a highly sensitive assay.
      • During the intervention period
      • After the study intervention period (i.e., after the last dose of study intervention is administered) for at least 2 months after the last dose of study intervention.
      • The Investigator evaluates the effectiveness of the contraceptive method in relationship to the first dose of study intervention.
    • Have a negative serum or highly sensitive urine pregnancy test, as required by local regulations, within 24 hours before the first dose of study intervention. If a urine test cannot be confirmed as negative (e.g., an ambiguous result), a serum pregnancy test is required.
  • Additional requirements for pregnancy testing during and after study intervention are in Safety Assessments and Procedures.
  • The Investigator reviews the medical history, menstrual history, and recent sexual activity to decrease the risk for inclusion of a female with an early undetected pregnancy.
  • Can give signed informed consent, as indicated in Study Governance, which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and this protocol.

Exclusion Criteria:

  • Ampullary cancer is excluded.
  • Rapid clinical deterioration other than malignancy which, in the opinion of the Investigator, may predispose to inability to tolerate treatment or study procedures.
  • Participants with active central nervous system (CNS) metastases causing clinical symptoms or metastases that require therapeutic intervention are excluded. Participants with a history of treated CNS metastases (by surgery or radiation therapy) are not eligible unless they have fully recovered from treatment, demonstrated no progression for at least 2 months, and do not require continued steroid therapy.

If an Investigator has a strong suspicion of HIV infection without known history for a participant in Screening, and the participant refuses testing, discuss with the Medical Monitor to assess eligibility.
      • Note: HIV testing is not mandated for study inclusion; however, if it is performed at any point in Screening or while on study, a site must consent the participant for HIV testing as per local standard guidance).
    • Active tuberculosis infection (clinical symptoms, physical or radiographic, and laboratory findings;
    • Active bacterial or fungal infection requiring intravenous systemic therapy (except as indicated, discuss alternative scenarios with the Medical Monitor).
  • Active autoimmune disease that might deteriorate when receiving an immunostimulatory agent:
    • Participants with diabetes type 1, vitiligo, alopecia, psoriasis, hypo- or hyperthyroid disease not requiring immunosuppressive treatment are eligible;

  • Clinically relevant diseases (e.g., inflammatory bowel disease) and/or uncontrolled medical conditions, which, in the opinion of the Investigator, might impair the participant’s tolerance or ability to participate in the study. Participants with history of bleeding diathesis or recent major bleeding events considered by the Investigator as high risk for study intervention are also excluded.
  • Any psychiatric condition that would prohibit the understanding or rendering of informed consent.
  • Participants who are not eligible for or have not been treated with 1L systemic chemotherapy will be excluded.
