For patients with non-resectable cholangiocarcinoma, gemcitabine with cisplatin is considered as the reference treatment in first line chemotherapy. However, the outcomes of these patients remain limited and therefore more effective drugs are warranted. The context of the disease and current data on sunitinib suggest that sunitinib may have activity in patients with advanced non resectable cholangiocarcinoma.

Thereby, it is proposed to conduct an open label single arm trial aiming evidencing activity of sunitinib in such a patient population.

The primary objective is to evaluate the overall survival of patients with advanced and unresectable cholangiocarcinoma treated continuously by sunitinib as second line at the dose of 37.5 mg per day, after one line of chemotherapy and to determine whether sunitinib deserves further studies in this indication.

The secondary objectives are

• To evaluate the criteria of efficacy
• To evaluate the effects of sunitinib on tumor angiogenesis
• To characterize the safety profile of sunitinib
• To identify markers associated with response to sunitinib

All female patients with reproductive potential must have a negative pregnancy test (serum or urine) within 7 days prior to starting study drug. Male patients must be surgically sterile or must agree to use effective contraception during the period of therapy. The definition of effective contraception will be based on the judgment of the investigator or a designated associate

18. Absence of any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before registration in the trial

19. Willingness and ability to comply with scheduled visits, treatment plans, laboratory tests and other study procedures

20. Registration in a national health care system (CMU included).

Exclusion Criteria:

1. Hilar cholangiocarcinomas, cholangiocarcinomas located in the gall bladder, hepatic capsule effraction, extrahepatic primary cholangiocarcinoma, carcinoma of the Water ampullum.
2. Prior treatment with other chemotherapy than gemcitabine and/or platinum.
3. Concomitant treatment with any chemotherapy, chemoembolization therapy, immunotherapy, antitumoral hormonotherapy or investigational anticancer agents..
4. Prior treatment with any tyrosine kinase inhibitors or anti-VEGF angiogenic inhibitors.
5. Diagnosis of any second malignancy within the last 5 years, except for adequately treated basal cell or squamous cell skin cancer, or in situ carcinoma of the cervix uteri.
