Clinical Trial Summary

This is an open label phase II trial to examine efficacy and safety of a novel combination of pembrolizumab plus induction GM-CSF in patients with advanced biliary cancers treated at University of California, San Francisco (UCSF).

This phase II study will examine the efficacy and safety of the novel combination of pembrolizumab plus induction GM-CSF in advanced biliary cancer patients with the hypotheses that the combination may increase proportion of patients with overall response compared to contemporary historical controls, with acceptable safety.

• Has untreated active Hepatitis B (e.g., HBsAg reactive).

• Has an active infection requiring systemic antibiotic therapy at time of enrollment.

• Treatment with antibiotic prophylaxis for indwelling biliary stent(s) or peri-procedural antibiotics for uncomplicated biliary stent exchanges is allowed and not an exclusion

• Hypersensitivity to pembrolizumab or any of its excipients.

• Has received treatment with an anti-cancer monoclonal antibody (mAb) within 4 weeks prior to study Day 1 or who has not recovered (i.e., = Grade 1 or at baseline) from adverse events due to agents administered more than 4 weeks earlier.

• Has received treatment with chemotherapy, targeted small molecule therapy, or radiation therapy to non-liver sites within 2 weeks prior to study Day 1 or who has not recovered (i.e., = Grade 1 or at baseline) from adverse events due to a previously administered agent administered more than 2 weeks earlier.

• Has had prior chemoembolization, bland embolization, radioembolization, local ablative therapies, radiation to liver tumors, or major surgery such as liver resection within 4 weeks prior to study enrollment or who has not recovered (i.e., = Grade 1 or at baseline) from adverse events due to intervention more than 4 weeks earlier.

• Has a known additional malignancy that is progressing or requires active treatment. Exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the skin that has undergone potentially curative therapy or in situ cervical cancer.

• Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Subjects with previously treated brain metastases may participate provided they are stable (without evidence of progression by imaging for at least four weeks prior to the first dose of trial treatment and any neurologic symptoms have returned to baseline), have no evidence of new or enlarging brain metastases, and are not using steroids for at least 7 days prior to trial treatment.

• Has 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.

• Has known history of or any evidence of active, non-infectious pneumonitis.

• Has had prior liver or other organ transplantation.

• Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator.

• Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.

• Is pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the trial, starting with the pre-screening or screening visit through 120 days after the last dose of trial treatment.

• Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti-PD-L2 agent.

• Has received a live vaccine within 30 days of planned start of study therapy.
