Description of intervention(s) / exposure

Afatinib (BIBW 2992) 40 mg per day, oral.
The appropriate number of afatinib tablets for 3 - 6 weeks of treatment will be provided to patients to be self administered at home. Patients will be asked to bring remaining trial medication at the end of each dosing period to the investigator site for a compliance check.
Patients remain on afatinib until progression, toxicity, patient wishes or clinician judgement mandate removal from study.
This is not primarily an efficacy study. It is a pilot translational study examining the effect of afatinib on the anti-tumour immune response in patients with advanced NSCLC.

Outcomes

Primary outcome [1]

The Primary Outcome Measure is the numbers and phenotype of the constituents of the immune cell population.
Whole blood is assayed for change in proliferating CD8+ T cells as a proportion of total CD8+ T cells following treatment. Specifically, the primary endpoint will be changes from baseline to week 3 and 6 in the proportion of Ki67+ and ICOS+ CD8+ T cells as a function of total CD8+ T cells.

Timepoint [1]

Baseline, Days 21, 42 & Day 28 after last dose of Afatinib

Secondary outcome [1]

To correlate immune responses with antitumour response in patients with NSCLC.

Antitumour response is assessed by radiological response using Response Evaluation Criteria in Solid Tumours (RECIST 1.1 assessed on CT).

Timepoint [1]

A CT scan will be performed at Baseline, Days 42, 84, then every 12 weeks thereafter until progression, and Day 28 after last dose of Afatinib.

Secondary outcome [2]

To correlate immune response with survival outcomes in patients with NSCLC.

Timepoint [2]

Baseline to time of death. This information will be sourced from the hospital database.

Non-randomised trial

Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)

Patients are registered to the study following eligibility check. Screening investigations are then performed prior to study treament. There is no treatment allocation procedure as the study is not randomised and all subjects receive study drug.

Statistical methods / analysis

All statistical analyses will be performed on the group as a whole, with secondary exploratory analyses with participants stratified by EGFR mutation status (known sensitive mutation; unknown mutation or mutation with unknown sensitivity; no mutation or known insensitive mutation).
Objective radiological responses will be reported as proportions of participants and as per RECIST 1.1.
Toxicity will be reported using the CTCAE version 3.0. Median survival and time to progression will be calculated from on-study time using the Kaplan-Meier method.
Translational data will be analysed longitudinally using a linear mixed model, and relationships with survival and toxicity analysed using multivariable analysis.
Change in proliferating CD8+ T cells as a proportion of total CD8+ T cells following treatment is the primary outcome. The standard deviation of change in this variable from day 0 to day 90 in a group of 10 healthy controls has been used for this calculation (SD=1.1). Data from patients undergoing chemotherapy showed a 50% increase in the proportion of proliferating CD8+ T cells 21 days after the start of treatment (from 4% to 6%) (McCoy et al. 2012).
A sample size of 20 patients will be adequate to detect a change in proliferating CD8+ T cells from 4% to 5.5 % with SD=1.1, a =0.05 and beta =0.8 using a linear mixed model.

Summary

Brief summary

This study is evaluating the effect of Afatinib on the anti-tumour immune response in patients with advanced non-small cell lung cancer.

Who is it for?
You may be eligible to join this study if you are aged 18 years or above and have been diagnosed with advanced non-small cell lung cancer (IIIb/IV). You also need to be willing to undergo study blood tests at Sir Charles Gairdner Hospital in Nedlands, Western Australia.

Study details
All participants in this study will undergo treatment with Afatinib. Afatinib is an oral drug which is known to be effective in treating some types of lung cancer, particularly those with a mutation in EGFR. The purpose of this research study is to determine how Afatinib affects the cells of the immune system during treatment for lung cancer. There is now evidence to suggest that some cancer treatment drugs may help the immune system to attack cancer cells. If this is the case, it might be possible to develop better cancer treatments by combining them with drugs that stimulate the immune system further. However, it is important to understand exactly how different drugs affect the immune system before deciding which combinations might work well together.

Treatment with Afatinib is a once daily tablet, divided into 6 week courses. Treatment will continue while it is of benefit to the patient, and will be stopped for safety reasons or if consent is withdrawn. Research blood samples will be taken at baseline, after 3 weeks and 6 weeks on treatment, and a final one 28 days after last dose of Afatinib. The research bloods will be used to characterise and measure the numbers of different immune cells in the blood, and how well they are reacting against the cancer. Routine blood tests will be required every 6 weeks while on Afatinib to monitor the safety of treatment as is standard for all patients having cancer treatment. Research bloods can be taken with routine bloods at the appropriate time points. A CT scan will be performed at baseline, at 6 weeks and 12 weeks after starting treatment and thereafter at 12-week intervals. A clinic visit is required at baseline, 3 weeks after starting treatment, and then on the first day of each course. Approximately 20 people at Sir Charles Gairdner Hospital only will participate in this study.

Public notes

This is not primarily an efficacy study. It is a pilot translational study examining the effect of afatinib on the anti-tumour immune response in patients with advanced NSCLC. However, the immune response will be correlated with treatment efficacy, as defined by radiological response (RECIST 1.1 assessed on CT), time to progression and overall survival.
