Study of Gemcitabine, Cisplatin, AB680 and AB122 During First Line Treatment of Advanced Biliary Tract Cancers (QUIC)

Running, not enrolling · Phase 2

Conditions studied: Biliary Tract Carcinoma, Cholangiocarcinoma, Bile Duct Cancer

In brief

This is a phase 2 study of gemcitabine, cisplatin, zimberelimab (AB122) and quemliclustat (AB680) in subjects with untreated advanced biliary tract cancers (BTC). The study will include a safety run-in involving 6 study participants. The goal of the safety run-in is to screen for early safety signals of the proposed drug combination. Trial enrollment can continue while full safety assessment is being completed for the first 6 subjects. Participants will receive 4 cycles of combination therapy as described. After 4 cycles (\~6 months), cisplatin will be discontinued, while gemcitabine, zimberelimab (AB122), and quemliclustat (AB680) will be continued. Subjects will be treated until disease progression or development of intolerable toxicities. In total, there will be up to 39 participants on the study.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Patients with cytologically or histologically confirmed BTC by AJCC version 8.
• Patients must have late stage (locally advanced, recurrent or metastatic) BTC. Patients must not have received systemic treatment for advanced disease. Prior adjuvant therapy is allowed as long as recurrences occurred 6 months or later from all treatment completion.
• Written informed consent and HIPAA authorization for release of personal health information. NOTE: HIPAA authorization may be included in the informed consent or obtained separately.
• Age ≥ 18 years at the time of consent.
• ECOG Performance Status of 0-2 within 28 days prior to registration.
• Presence of measurable or evaluable disease, as defined by RECIST v1.1.
• Adequate organ function as detailed in the protocol.
• Females of childbearing potential who are sexually active with a male able to father a child must have a negative pregnancy test (serum or urine) within 14 days prior to registration. NOTE: Biliary cancer may secrete hormones to produce a false-positive pregnancy test. Female subjects of childbearing potential with a positive pregnancy test should have a thorough history and additional work up as determined by the treating physician to rule out pregnancy (e.g. serial βHCG measurements, ultrasound). Once pregnancy has been ruled out, the subject may proceed with screening and enrollment.
• 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). See the protocol for specific timeframes for each drug.
• Ability of the subject to understand and comply with study procedures for the entire length of the study, as determined by the enrolling physician or protocol designee.

You may not qualify if…

• Prior therapy with gemcitabine, cisplatin, or any immune checkpoint inhibitors for the treatment of BTC.
• Known hypersensitivity to recombinant proteins, or any excipient contained in treatment medication formulations.
• 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.
• NOTE: participants with asthma who require intermittent use of bronchodilators, inhaled corticosteroids, or local corticosteroid injections will not be excluded from this study.
• History of solid organ or allogeneic bone marrow transplantation.
• Pregnant or breastfeeding. NOTE: breast milk cannot be stored for future use while the mother is being treated on study.
• 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.
• Untreated central nervous system (CNS) metastasis. Screening of asymptomatic patients for CNS metastasis is not required for enrollment.
• Underlying medical conditions that, in the Investigator's or Sponsor's opinion, will make the administration of IP(s) hazardous, including but not limited to
• Interstitial lung disease, including history of interstitial lung disease or non-infectious pneumonitis.
• Active viral, bacterial, or fungal infections requiring parenteral treatment within 14 days of the initiation of the study treatments.
• History of trauma or major surgery within 28 days prior to the first dose of IP. (Note that placement of central venous access catheter (e.g., port or similar) is not considered a major surgical procedure.
• Treatment with palliative radiation therapy within 14 days of study treatment initiation.
• Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.
• Significant dementia or other mental condition that precludes the participant's ability to consent to the study.
• Use of any live vaccines against infectious diseases within 4 weeks (28 days) of initiation of investigational products.
