- Brief summaryBackground of the study:
Substantial evidence has accumulated that estrogen receptors are expressed in NSCLC. In particular, the Estrogen Receptor B (ERb) has shown to be expressed in over 50% of resected NSCLC of both men and women and is associated with adverse outcome. Lung cancer cells respond to estrogens with proliferation and it is thought that this effect is mainly mediated through the ERb pathway as it is this type of ER that is expressed abundantly in both normal and malignant lung tissue. Subsequent studies have shown that treatment of NSCLC cells in vitro with oestradiol results in downregulation of EGFR, whereas treatment with the antioestrogen fulvestrant increased EGFR expression. Modulation of the EGFR pathway effects ERb expression: treatment with epidermal growth factor reduced ERb expression whereas gefitinib, an EGFR TKI, increased it. These data suggest that the two pathways can substitute for one another when either is inhibited, whereas stimulation of one pathway shuts down the other. This reciprocal effect provides the rationale for simultaneous targeting of both pathways in lung cancer. Indeed, in vitro studies have shown that NSCLC cells treated by fulvestrant and gefitinib in combination were more likely to undergo apoptosis and the combination had significantly more antiproliferative effects as compared to treatment with either agent alone. In addition, there seems to exist a second type of ER-EGFR interaction in the nucleus that is independent of estrogen. Although estrogen may be produced locally in the lung, the former provides the rationale to test the combination of an anti-estrogen and EGFR TKI in both men and women independent of menopausal status.
Here, we propose to perform a phase II study of the combination of fulvestrant and gefitinib in patients with relapsed EGFR mutated NSCLC. Recently the standard dose for fulvestrant in metastatic breast cancer, where the product has itís only registration, changed from 250 mg monthly to 500 mg monthly plus a loading dose of 500 mg at day 14. This higher dose gives a better efficacy of the drug without adding additional toxicity.

Objective of the study:
Primary objective:
To assess the rate of no progression (NPR) at 8 weeks following treatment with the combination of gefitinib and fulvestrant in EGFR mutated patients who failed previous treatment with reversible EGFR TKIís (gefitinib or erlotinib).
Secondary objective:
1. Quantitative and qualitative toxicities of this regimen;
2. Duration of response for responding patients;
3. Time to progression or death;
4. Progression free survival;
5. Overall survival.
Additional exploratory study objectives:
Correlation of RNA from trombocytes with time to progression and/or overall survival.

Study design:
This will be a single-centre, open-label Phase II study.

Statistical design:
Simonís optimal two-stage design to test if the drug combination is effective.

Study drugs/ intervention:
The doses and schedule of gefitinib will be 250 mg/day per os. For fulvestrant the dose and schedule will be 500 mg injection intramuscular on day 1, 14, 28 and every 28 days thereafter. Fulvestrant will be provided free of charge as part of the grant for this Investigator Sponsored Study by AstraZeneca.

Duration of treatment: Gefitinib and fulvestrant will be continued until unacceptable toxicity or tumour progression. In case of documented tumour progression, patient will discontinue the trial and will receive further treatment as per investigator decision. In responding patients tumour assessments will be performed after 8 weeks of therapy. In case of documented tumour progression, patient will discontinue the trial and will receive further treatment as per investigator decision. Recruitment is expected to be completed within 2 years of the registration of the first patient. Patients will remain on treatment until disease progression, withdrawal due to toxicity or withdrawal due to patients wish. The study will be terminated after every patient had a follow up of at least 6 months. For patients with complete remission (CR), partial response (PR) and stable disease (SD), treatment will continue until progression and/or unacceptable toxicity and/or patient withdrawal.

Study population:
Patients with pathologically documented NSCLC with an EGFR mutation, who failed previous treatment with reversible EGFR TKIís (gefitinib or erlotinib).
