• Status: Active, not recruiting
• Trial end date: 2024-12-31
• Target enrollment: 0
• Participant gender: All

Summary

This is a multinational, multicenter, randomized, open-label, Phase 3 study comparing the efficacy and safety of treatment with dacomitinib (PF-00299804) to treatment with gefitinib in patients with locally advanced or metastatic non-small cell lung cancer, with epidermal growth factor receptor EGFR-activating mutation (s). Analyses of primary objective (Progression Free Survival) will be done as defined in the protocol.

• Collaborator: Pfizer
• Treatments: Gefitinib

Criteria

Inclusion Criteria:

• Evidence of histo or cytopathology confirmed, advanced NSCLC (with known histology) with the presence of EGFR-activating mutation (exon 19 deletion or the L858R mutation in exon 21).

• It is acceptable for subjects with the presence of the exon 20 T790M mutation together with either EGFR-activating mutation (exon 19 deletion or the L858R mutation in exon 21) to be included in this study

• No prior treatment with systemic therapy for locally advanced or metastatic NSCLC. Minimum of 12 months disease free interval between completion of neoadjuvant/adjuvant systemic therapy and recurrence of NSCLC

• Adequate tissue sample must be available for central analyses.

• Adequate renal, hematologic, liver function.

• ECOG PS of 0-1.

• Radiologically measurable disease.

Exclusion Criteria:

• Any evidence of mixed histology that includes elements of small cell or carcinoid lung cancer.

• Any other mutation other than exon 19 deletion or L858R in exon 21, with or without the presence of the exon 20 T790M mutation.

• Any history of brain metastases or leptomeningeal metastases.

• Any previous anti-cancer systemic treatment of early, locally advanced, or metastatic NSCLC.

• Any surgery(not including minor procedures such as lymph node biopsy), palliative radiotherapy or pleurodesis within 2 weeks of baseline assessments

• Any clinically significant gastrointestinal abnormalities that may impair intake, transit or absorption of the study drug.

• Current enrollment in another therapeutic clinical study.

• History of, or currently suspected, diffuse non-infectious pneumonitis or interstitial lung disease

• Uncontrolled medical disorders.

• Prior malignancy and concurrent malignancy except for non melanoma skin cancer or in-situ cervical cancer with no evidence of active disease.

• Use of narrow therapeutic index drugs that are CYP2D6 substrates from screening to randomization.
