Pembrolizumab and Afatinib in Patients With Non-small Cell Lung Cancer With Resistance to Erlotinib
Study Details
Study Description
Brief Summary
This phase I/Ib trial studies the side effects and best dose of pembrolizumab when given together with afatinib dimaleate in treating patients with non-small cell lung cancer that has spread to other places in the body and usually cannot be cured or controlled with treatment, or has come back and does not respond to erlotinib hydrochloride. Monoclonal antibodies, such as pembrolizumab, may interfere with the ability of tumor cells to grow and spread. Afatinib dimaleate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving pembrolizumab and afatinib dimaleate together may be an effective treatment for non-small cell lung cancer.

Phase 1 |
Detailed Description
PRIMARY OBJECTIVES:
- To evaluate the safety and tolerability of MK-3475 (pembrolizumab) when given in combination with afatinib (afatinib dimaleate) in patients with advanced or metastatic non-small cell lung cancer with epidermal growth factor receptor (EGFR) activating mutations who have progressive disease on erlotinib (erlotinib hydrochloride).
SECONDARY OBJECTIVES:
- To assess in a preliminary manner the efficacy of this combination (response rate, disease control rate and progression free survival).
OUTLINE: This is a dose de-escalation study of pembrolizumab. Patients assigned to 1 of 2 treatment arms.
ARM I (DOSE DE-ESCALATION COHORT): Patients receive afatinib dimaleate orally (PO) once daily (QD) on days 1-21 and pembrolizumab intravenously (IV) over 30 minutes on day 1.
ARM II (EXPANSION COHORT): Patients receive pembrolizumab IV over 30 minutes on day 1 for 2 courses. Beginning course 3, patients receive afatinib dimaleate PO and pembrolizumab IV as in Arm I.
In both Arms, courses repeat every 21 days (for up to 2 years for pembrolizumab) in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days and then every 12 weeks thereafter.

Outcome Measures
Primary Outcome Measures
- Maximum tolerated dose (MTD) recommended dose of pembrolizumab in combination with lead in pembrolizumab and afatinib dimaleate [Day 21]
Descriptive summaries will be provided for number and proportion with specific type and grade of toxicities.
- Recommended phase II dose [Day 21]
Will be determined by the overall assessment of the MTD and toxicities observed in the dose de-escalation portion of this study.
Secondary Outcome Measures
- Overall response rate per RECIST 1.1 [Up to 3 years]
Descriptive summaries will be provided for numbers and proportion of patients responding.
- Progression free survival [Time from start of treatment to time of progression or death, whichever occurs first, assessed up to 3 years]
Kaplan-Meier plot and life-table summary will be used.
Other Outcome Measures
- Changes in plasma EGFR-mutant DNA levels [Baseline to up to 3 years]
Standard descriptive methods will be used to summarize the baseline levels and changes in baseline levels will allow to examine whether observed patterns are consistent with hypothesized patterns.
- Changes in PDL1 expression by immunohistochemistry [Baseline to up to 3 years]
Descriptive associations with response rate and PFS will be performed. Standard descriptive methods will be used to summarize the baseline levels and changes in baseline levels will allow to examine whether observed patterns are consistent with hypothesized patterns.
