BIBW 2992 as add-on to Gem/Cis in Advanced Biliary Tract Cancer

Open-label, Uncontrolled, Multicenter Phase I/Ib Trial to Investigate Safety and Efficacy of BIBW 2992 and Standard Gemcitabine/Cisplatin in Chemo-naïve Patients With Advanced Biliary Tract Adenocarcinoma

An open-label, uncontrolled, multicenter phase I/Ib trial to investigate safety and efficacy of BIBW 2992 added to the standard therapy of Gemcitabine/Cisplatin in chemo-naïve patients with advanced and/or metastatic adenocarcinoma of the biliary tract

The primary objective is safety and toxicity, including maximum tolerated dose, of BIBW 2992 when given as add-on therapy to Gem/Cis.

Inclusion Criteria:

• Male and female patients aged ≥ 18 years

• Signed and dated written informed consent,

• Histologically confirmed adenocarcinoma of the gallbladder or intrahepatic bile ducts or extrahepatic bile ducts (metastasized) or histologically proven hepatic metastases of an earlier resected and histologically proven biliary tract cancer or a Klatskin tumour (hilar cholangiocarcinoma)

  • with pain and biliary obstruction controlled
  • adequate biliary drainage, no uncontrolled infection
  • ECOG Performance Status of 0-1
  • LFTs: bilirubin (total) ≤ 1.5 x ULN, ALT/ AST/ alkaline phosphatase ≤ 3 2.5 x ULN (≤ 5 x ULN if liver metastases are present)
  • No prior systemic treatment i) previous adjuvant chemotherapy is allowed (completed ≥ 6 months if containing Gemcitabine or platinum salts); ii) previous irradiation (external radiotherapy, brachytherapy, chemoembolization) and PDT are allowed, provided that there is still at least one unidimensionally measurable target lesion in an untreated area

• Resolution of all side effects of prior surgical procedures to CTCAE grade ≤ 1 (except for the laboratory values specified below)

• At least 4 weeks from any major surgery (at first dose of study drug)

  • Total bilirubin ≤ 1.5 times the upper limit of normal
  • ALT and AST ≤ 2.5 x institutional upper limit of normal (in case of liver metastases: ALT and AST ≤ 5 x institutional upper limit of normal)
  • Prothrombin rate > 60% or INR < 1.5

Main exclusion criteria

• Large surgery (except diagnostic biopsy) or smaller surgical procedures, external radiotherapy, brachytherapy, or PDT within 30 days prior to start of treatment.
• Other tumor type than adenocarcinoma (e.g. leiomyosarcoma, lymphoma) or a second cancer except in patients with squamous or basal cell carcinoma of the skin or carcinoma in situ of the cervix which has been effectively treated.
• History of acute cardiac disease: congestive heart failure > NYHA class 2; active CAD (MI more than 6 months prior to study entry is allowed);
