Trial of BIBW 2992 (Afatinib) + Cetuximab in Non-Small Cell Lung Cancer

Phase 1
Completed
Conditions
Carcinoma, Non-Small-Cell Lung
Interventions
Registration Number
NCT01090011
Lead Sponsor
Boehringer Ingelheim
Brief Summary

The primary objective of this trial is to determine the maximum tolerated dose (MTD) and recommended Phase II doses for the combination of BIBW 2992 and cetuximab in patients with non-small cell lung cancer and acquired resistance to erlotinib or gefitinib.

Overall safety, pharmacokinetics and anti-tumor activity for the combination of BIBW 2992 and cetuximab in patients with non-small cell lung cancer and acquired resistance to erlotinib, gefitinib or BIBW 2992 will be evaluated as secondary objectives.

Initially a standard, 3+3 dose escalation will be performed to determine the MTD of BIBW 2992 when administered together with cetuximab in patients with advanced non small cell lung cancer and acquired resistance to erlotinib or gefitinib.

Subsequently, the preliminary efficacy and safety of the identified MTD of cetuximab administered with BIBW 2992 will be explored in a combo arm via a further expansion of MTD cohort up to a total of 140 EGFR mutation positive NSCLC with acquired resistance to erlotinib/gefitinib.

Furthermore, the safety and preliminary anti-tumor activity of the combination therapy in EGFR mutant NSCLC patients who developed acquired resistance (AR) to BIBW 2992, will be assessed in a sequential arm. The sequential arm will use a two-stage design with an early stopping rule after 12 patients with acquired resistance to BIBW 2992 have received up to 5 courses of BIBW 2992 plus cetuximab. If no responses are seen in 12 patients during 5 courses of combination therapy, accrual in the sequential arm will stop. If 1 or more responses are observed, the sequential arm will expand up to about 40 patients.

Primary Outcome Measures
NameTimeMethod
The Primary Endpoint is the Occurrence of Dose Limiting Toxicity (DLT).from day 1 treatment until progression or undue toxicity, up to 28 days

A DLT was defined as an AE or laboratory abnormality that a) related to the study regimen; b) or met any of the following criteria:

* CTCAE Grade 2 or higher decrease in cardiac left ventricular function

* CTCAE Grade 2 diarrhea lasting for 7 or more days, despite appropriate use of standard anti-diarrheal therapy

* CTCAE Grade ≥3 diarrhea despite appropriate use of standard anti-diarrheal therapy for at least 2 days

* CTCAE Grade ≥3 nausea and/or vomiting despite appropriate use of standard anti-emetics for at least 3 days

* CTCAE Grade ≥3 rash despite standard medical management

* CTCAE Grade ≥3 fatigue lasting for more than 7 days

* CTCAE Grade 4 hypomagnesaemia or Grade 3 hypomagnesaemia with clinical significant sequelae

* All other toxicities of CTCAE Grade ≥3 (except alopecia, and allergic reaction) leading to an interruption of afatinib and/or cetuximab for more than 14 days until recovery to baseline or Grade 1, whichever was higher.
