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

Completed · Phase 1

Conditions studied: Carcinoma, Non-Small-Cell Lung

In brief

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.

You may qualify if…

Pathologically or cytologically confirmed Stage IIIB/IV non-small cell lung cancer or recurrent disease following locoregional treatment
Either or both of the following:
A tumor which harbors an Epidermal Growth Factor Receptor (EGFR) -mutation known to be associated with drug sensitivity (i.e., G719X, exon 19 deletion, L858R, L861Q) from previous tumor biopsy or surgery. A tumor which harbors exon 20 insertion or de novo T790M mutation is eligible for the treatment in the sequential arm 2) Objective clinical benefit from treatment with an Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor (EGFR TKI) as defined by either
Documented partial or complete response (Response Evaluation Criteria in Solid Tumors, RECIST), or
Stable disease >=6 months as defined by RECIST in absence of radiographic progression after initiation of gefitinib or erlotinib; or stable disease/PR/CR >=12 weeks as defined by RECIST after initiation of BIBW 2992 3. Systemic progression of disease (RECIST v1.1) while on continuous treatment with erlotinib or gefitinib or BIBW 2992 within the last 30 days. Patients whose disease progresses only in the central nervous system (CNS) are not eligible 4. No intervening systemic therapy between cessation of gefitinib or erlotinib or BIBW 2992 and initiation of the treatment in the study 5. Adequate tumor-derived material such as fresh or archived tumor tissue or pleural fluid from malignant pleural effusion after disease progression on erlotinib/gefitinib/BIBW 2992 prior to the study entry must be made available for EGFR mutation analyses 6. Patients aged 18 years or older 7. Life expectancy of at least three (3) months 8. Eastern Cooperative Oncology Group (ECOG) performance score 0-2 9. Written informed consent that is consistent with ICH-GCP guidelines

You may not qualify if…

Prior treatment with EGFR targeting antibodies; prior severe infusion reaction to a monoclonal antibody
Adverse events due to major surgery (at least 28 days after) or minor surgery not recovered to CTC grade 1 or less. Surgical wounds must be healing without clinical evidence of infection prior to study treatment to be eligible.
Radiotherapy less than two weeks prior to the start of the study treatment
Systemic chemotherapy, hormonal therapy, immunotherapy, or experimental or approved proteins/antibodies (except erlotinib/gefitinib/BIBW 2992) <=30 days before study treatment
Less than three days from prior treatment with gefitinib or erlotinib. Patients with adverse events related to gefitinib or erlotinib must recover to CTC AE grade 1 or less to be eligible. No need to stop BIBW 2992 before start of the study treatment for patient who progressed on BIBW 2992 from a separate clinical trial/treatment setting
Brain metastases, which are symptomatic. Patients with treated, asymptomatic brain metastases are eligible if there has been no change in brain disease status for at least four (4) weeks, no history of cerebral oedema or bleeding in the past four (4) weeks. Anticonvulsant therapy will be allowed if patient is stable on anticonvulsant treatment.
Other malignancies diagnosed within the past five (5) years (other than non melanomatous skin cancer, ductal carcinoma in situ and in situ cervical cancer)
Known pre-existing interstitial lung disease
Significant or recent acute gastrointestinal disorders with diarrhea as a major symptom e.g., Crohns disease, malabsorption, or Common Toxicity Criteria for Adverse Events (CTCAE) grade >2 diarrhea of any etiology
Women of childbearing potential (WOCBP), or men who are able to father a child, unwilling to use a medically acceptable method of contraception during the trial; pregnancy or breast-feeding
