Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients with CCA have poor outcomes, as a consequence of the very aggressive nature of the disease, and the limited treatment options. Thus there is a significant unmet medical need for additional treatment options for use in this patient population. As in most other tumor entities however, only a fraction of patients respond to immunotherapy alone. Evidence suggests that those patients might preferentially have tumors that have favorable mutational landscapes, express the PD-L1 and/ or contain preexisting tumor-infiltrating CD8+ T cells that are inhibited locally, e.g., by PD-1 engagement. In order to increase the proportion of patients who could ultimately benefit from immunotherapies, it is important to develop strategies that can be employed for converting tumor microenvironments lacking T cell infiltration to ones displaying antitumor T-cell immunity and therefore to sensitize tumors to checkpoint inhibition therapy. Therefore, the aim of this study is to determine the combination of durvalumab and tremelimumab in addition with gemcitabine or in addition with gemcitabine and cisplatin in treatment-naïve patients with advanced, unresectable and/or metastatic cholangio- and gallbladder carcinoma.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

4. Performance status (PS) ≤ 1(ECOG scale).
5. At least one measurable site of disease as defined by RECISTv1.1 criteria.
6. Adequate bone marrow and renal function including the following: Hemoglobin

≥ 9.0 g/dL; absolute neutrophil count ≥ 1.5 x 10\^9/L; platelets ≥ 100 x 10\^9 /L; Creatinine ≤ 1.5 x upper normal limit.
7. Calculated creatinine clearance ≥40 mL/min as determined by the Cockcroft- Gault equation (using actual body weight)
8. Adequate hepatic function (with stenting for any obstruction, if required) including the following: Total bilirubin ≤ 2x upper normal limit; AST (SGOT), ALT (SGPT) ≤ 5 x upper normal limit; prothrombin time ≥ 60%; albumin ≥ 30 g/L.
9. Female patients with reproductive potential must have a negative urine or serum pregnancy test within 7 days prior to start of trial.
10. Evidence of post-menopausal status or negative urinary or serum pregnancy test for female pre-menopausal patients. Women will be considered postmenopausal if they have been amenorrheic for 12 months without an alternative medical cause. The following age-specific requirements apply:

* Women \<50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatments and if they have luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution or underwent surgical sterilization (bilateral oophorectomy or hysterectomy).
* Women ≥50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatments, had radiation-induced menopause with last menses \>1 year ago, had chemotherapy-induced menopause with last menses \>1 year ago, or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy or hysterectomy).
11. The patient is willing and able to comply with the protocol for the duration of the study, including hospital visits for treatment and scheduled follow-up visits and examinations.

* Patients with Grade ≥2 neuropathy will be evaluated on a case-by-case basis after consultation with the Study Physician.
* Patients with irreversible toxicity not reasonably expected to be exacerbated by treatment with durvalumab or tremelimumab may be included only after consultation with the Study Physician.
6. Any concurrent chemotherapy, IMP, biologic, or hormonal therapy for cancer treatment. Concurrent use of hormonal therapy for non-cancer-related conditions (eg, hormone replacement therapy) is acceptable. Note: Local treatment of isolated lesions for palliative intent is acceptable (eg, local radiotherapy).
7. Radiotherapy treatment to more than 30% of the bone marrow or with a wide field of radiation within 4 weeks of the first dose of study drugs.
8. Major surgery (as defined by the Investigator) within 4 weeks prior to the first dose of the investigational product (IMP) of starting the study and patients must have recovered from effects of major surgery. Note: Local non-major surgery for palliative intent (eg, surgery of isolated lesions, per-cutaneous biliary drainage or biliary stenting) is acceptable.
9. History of allogenic organ transplantation.

11. Uncontrolled intercurrent illness, including but not limited to, ongoing or active infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, interstitial lung disease, serious chronic gastrointestinal conditions associated with diarrhea, or psychiatric illness/social situations that would limit compliance with study requirement, substantially increase risk of incurring AEs or compromise the ability of the patient to give written informed consent
12. History of another primary malignancy except for:

* Malignancy treated with curative intent and with no known active disease ≥5 years before the first dose of IMP and of low potential risk for recurrence
* Adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease
* Adequately treated carcinoma in situ without evidence of disease
13. History of leptomeningeal carcinomatosis
14. Brain metastases or spinal cord compression. Patients with suspected brain metastases at screening should have a CT/ MRI of the brain prior to study entry.
15. History of active primary immunodeficiency
16. Active infection including tuberculosis (clinical evaluation that includes clinical history, physical examination and radiographic findings, and TB testing in line with local practice), hepatitis B (known positive HBV surface antigen \[HBsAg) result\], hepatitis C, or human immunodeficiency virus (positive HIV 1/2 antibodies). Patients with a past or resolved HBV infection (defined as the presence of hepatitis B core antibody \[anti-HBc\] and absence of HBsAg) are eligible. Patients positive for hepatitis C (HCV) antibody are eligible only if polymerase chain reaction is negative for HCV RNA.
