Clinical Trial Summary

The investigators are doing this research program to find out if the investigational drug, afatinib which is a medication known to block the function of the ErbB2 protein might help standard chemotherapy, in particular paclitaxel, work better.

Afatinib (GILOTRIF) is a highly potent, irreversible inhibitor of the EGFR and HER2. On July 12, 2013 the United States Food and Drug Administration (US FDA) approved afatinib for the first-line treatment of patients with metastatic non-small cell lung cancer whose tumors had specific EGFR gene mutations (exon 19 deletions or exon 21 i.e. L858R substitution mutations) as detected by an FDA approved test.

Paclitaxel is a standard, anti-cancer medicine that has been approved by the US Food and Drug Administration (FDA) for the treatment of lung cancer.

The combination of Afatinib and Paclitaxel are considered investigational when used in this research program. An investigational drug is a drug that is not approved by the FDA for its indication.

Description:

Standard Procedures:

Subjects are offered second line chemotherapy with paclitaxel 80 mg/m2 intravenous infusion over 60 minutes on days 1, 8, and 15 of a 28-day cycle until disease progression or intolerable toxicity.

Experimental Procedures:

In addition to the standard chemotherapy, afatinib 40 mg orally once daily will be administered starting on the first day of paclitaxel. Translational studies to assess circulating tumor cells at the start of therapy and then at several later time points, including at the time of progression. These studies will assess the correlation of circulating tumor cell numbers with radiographic response and pilot studies will also be conducted to assess HER2 expression, HER2 genomic amplification, HER2 pathway activation and secondary genetic changes in the HER2 coding sequence as well as other pathway components.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change of tumor burden (in centimeters) for participants during protocol therapy		Change from Baseline Tumor burden, measured every 8 weeks, up to approximately 4 years
Secondary	Number of participants with adverse events.	Safety of BIBW 2992 will be evaluated as indicated by intensity and incidence of adverse events, graded according to US National Cancer Institute (NCI) Common Terminology for Adverse Events (CTCAE) Version 4.0. Safety endpoints include: events leading to dose reduction; events leading to permanent treatment discontinuation; the overall incidence and CTC criteria grade of adverse events, as well as relatedness of adverse events to treatment; causes of death	up to approximately 36 months
Secondary	Total number of circulating tumor cell (CTC) numbers.	CTC number changes from cycle 1, day 1 to cycle 2/3, day 1 will be correlated with response rate, progression-free survival as well as skin toxicity.	up to approximately 36 months
Secondary	Clinical benefit in progression free survival.		every 3 months up to approximately 4 years
Secondary	Clinical benefit in overall survival.		every 3 months up to approximately 4 years
Secondary	ErbB2 levels benefit during therapy.	Diagnostic tumor specimens will be retrieved for all subjects participating in the protocol. These specimens will be used for confirmation of ErbB2 status as well as correlative analyses of clinical response.	up to approximately 4 years
