Study Overview
Early phase 1 study evaluating the safety of autologous dendritic cells (immune cells generated from patients' own white blood cells, grown in a special lab, and trained to stimulate the immune system against the tumor) and a vaccine (Prevnar) in treating patients with liver cancer that cannot be removed by surgery after undergoing radiotherapy.

Study Purpose

  • Evaluate the safety of autologous dendritic cells and a vaccine (Prevnar) in treating patients with liver cancer that cannot be removed by surgery after undergoing radiotherapy.

  • Identify and characterize responses of the immune system in patients with liver cancer treated with radiotherapy followed by autologous dendritic cells and a vaccine (Prevnar).

Inclusion Criteria

  • Age ≥18 years

  • Histologic confirmation of intrahepatic cholangiocarcinoma

  • Unresectable intrahepatic cholangiocarcinoma

  • Measurable or evaluable disease

  • All lesions should be treatable by radiotherapy while meeting normal tissue constraints.

  • Tumor lesions should be accessible using an ultrasound-guided approach for dendritic cell injection into the tumor

  • No evidence of tumor outside of the liver (excluding tumor clots) by computed tomography (CT) or magnetic resonance imaging (MRI) scan

  • Patients who are not candidates for surgical treatment or for ablation with curative intent Adequate organ functions

  • ECOG Performance Status (PS) 0 or 1

Exclusion Criteria

  • Co-morbid systemic illnesses or other severe concurrent disease

  • Immunocompromised patients and patients known to be HIV positive and currently receiving antiretroviral therapy.

  • Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.

  • Other active malignancy ≤3years prior to registration. EXCEPTIONS: Non-melanotic skin cancer or carcinoma-in-situ of the cervix.

  • Active autoimmune disease such as autoimmune hepatitis, Crohn’s disease, rheumatoid arthritis, Sjögrens’ disease, systemic lupus erythematosus, or similar conditions.

  • Child Pugh class B or C cirrhosis of the liver

  • Barcelona Clinic Liver Cancer (BCLC) stage D disease

  • Previously received immune modulating therapies

  • Corticosteroids ≤2 weeks prior to registration, including oral, IV, subcutaneous, or inhaled routes of administration. NOTE: Patients on chronic corticosteroids may enroll if they receive less than 10 mg/day of prednisone (or equivalent)

  • Prior liver radiation, including radioembolization

Required Tests Prior to Study

  • Computed tomography (CT) or magnetic resonance imaging (MRI) scan

  • Bloodwork to determine baseline organ functions, tumor markers, and immune cells

  • Apheresis (isolation) of immature white blood from a patient’s own blood

Potential Side Effects

  • Inflammatory symptoms such as fever, chills, nausea, vomiting, diarrhea, rash, can occur

  • Pain at injection site
