Phase 1

Terminated

• Conditions: Metastatic Disease
• Interventions: Drug: BIBW 2992

• Registration Number: NCT01679405
• Lead Sponsor: Johannes Gutenberg University Mainz

Brief Summary

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

Detailed Description

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

  • 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

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

• Life expectancy of at least 12 weeks.

• Cardiac left ventricular function with resting ejection fraction (LVEF) ≥ 50%

• Adequate bone marrow, liver and renal function as assessed by the following laboratory requirements to be conducted within 7 days prior to start of therapy:

Arm && Interventions

Group	Intervention	Description
Dose level 1 (Part A)	BIBW 2992	30 mg BIBW 2992, Gemcitabin (1.000 mg/m² BSA i.v.)/Cisplatin (25 mg/m² BSA i.v.)
Dose level -1 (Part A)	BIBW 2992	30 mg BIBW 2992, Gemcitabin (800 mg/m² BSA i.v.)/Cisplatin (20 mg/m² BSA i.v.)

Primary Outcome Measures

Name	Time	Method
Number of Adverse Events	Treatment period: up to eight cycles (maximum 8 months). 12 months follow-up period.	In part A the maximum tolerated dose (MTD) of BIBW 2992 administered continuously to the standard therapy of Gemcitabine / Cisplatin (Gem/Cis) (administered together on day 1 and 8 of a three-week cycle) will be evaluated in a 2 step dose escalation.; Safety and toxicity will be evaluated as described and considered primary for part B of the study.

Secondary Outcome Measures

Name	Time	Method
Objective Response Rate	Treatment period: up to eight cycles (maximum 8 months).	Response was assessed by means of RECIST 1.1 criteria for target lesions, non-target lesions and the appearance of new lesions. Objective response was defined as the CR, PR or SD at end of treatment
Time to Progress (TTP)	Treatment period: up to eight cycles (maximum 8 months). 12 months follow-up period.	Median time to progress (according to RECIST 1.1 criteria) including the 95% confidence intervals were determined using Kaplan-Meier estimates. Time from start of treatment to first documentation of objective tumour progression. Deaths were censored at the time of death.
Overall Survival (OS)	Time from start of treatment to death due to any cause. Time to last observation will be used if a patient has not died and OS for the patient will be considered censored. Estimated time period: up to 76 weeks	Median overall survival time including the 95% confidence interval were determined using Kaplan-Meier estimates.
Tumor Control Rate	Treatment period: up to eight cycles (maximum 8 months).	Tumor control rate is defined as the best tumour response (confirmed partial or complete response, stable disease) that is achieved until end of treatment according to Recist 1.1.
