Brief Summary

This is an interventional, prospective multicenter, open-label, phase II study in patients after curative surgery for BTC in a classic adjuvant situation, consisting of a two arm feasibility pilot part with a randomized pick-the-winner design and an option to proceed into a randomized phase 2/3 trial in order to compare the winner with the current SOC (capecitabine).

Detailed Description

The primary objective is to assess the anti-tumor activity of the combination of durvalumab and tremelimumab with or without capecitabine by the recurrence-free survival rate after 12 months (RFS@12).

Secondary objectives are to assess the efficacy by recurrence-free surviaval (RFS) and overall survival (OS); to assess safety of the combination treatments (AEs, impact on liver function, use of subsequent therapies); to assess quality of life (QoL).

Exploratory objective is to perform correlation analysis between selected molecular parameters and clinical data to identify molecular biomarkers predictive for RFS and OS.

Patients will be stratified according to the tumor site (ICC vs. ECC vs. gallbladder) and resection status (R0 vs. R1).

In this pilot trial phase, a pick the winner design is applied to determine wether treatment with durvalumab and tremelimumab in combination with or without capecitabine is more promising.

In the initial pilot phase, 40 patients with histologically proven and curatively resected biliary tract cancer (intrahepatic, hilar or distal CCA as well gallbladder carcinoma) without metastatic disease, will be enrolled in a 1:1 randomized design (i.e. 20 patients per Arm).

Patients will be recruited from up to 15 sites and patients withdrawn from the trial will not be replaced.

• AST (SGOT) and ALT (SGPT) ≤ 2.5 x UNL
• Serum creatinine ≤ 1.5 x UNL or creatinine clearance (measured by 24h urine) ≥ 40 mL / min (i.e., if the serum creatinine level is > 1.5 x UNL, then a 24-h urine test must be performed to check the creatinine clearance to be determined).

7. Adequate coagulability, as determined by the International Normalized Ratio (INR) ≤ 1.5 and partial thromboplastin time (PTT) ≤ 5 seconds above the UNL (unless anti-coagulation therapy has been given).

8. Patients of reproductive age must be prepared to use a suitable contraceptive method during the study and up to 3 months after the end of treatment. A suitable method of contraception is defined as surgical sterilization (e.g., bilateral fallopian tube ligation, vasectomy), hormonal contraception (implantable, patch, oral), and double barrier methods (each two-fold combination of intrauterine pessary, condom for men, or women with spermicidal gel, Diaphragm, contraceptive sponge, cervical cap). Women of child-bearing potential must have a negative serum pregnancy test within the last 7 days prior to the start of study therapy.

Men who are sexually active with WOCBP must use any contraceptive method with a failure rate of less than 1% per year. Men receiving IMP and who are sexually active with WOCBP will be instructed to adhere to contraception for a period of 7 months after the last dose of investigational products (durvalumab and tremelimumab).

Women who are not of childbearing potential (i.e., who are postmenopausal or surgically sterile) as well as azoospermic men do not require contraception).
