About this study
Official title: A Randomized Open-label Phase II Study of Letrozole Plus Afatinib Versus Letrozole Alone in First-line Treatment of Advanced ER+, HER2- Postmenopausal Breast Cancer With Low ER Expression
The purpose of the study is to compare the efficacy of treatment with afatinib plus letrozole to treatment with letrozole alone in women diagnosed with a specific type of breast cancer.
Read the detailed description
This is an open-label, multicenter, international, randomized, Phase II clinical trial that will assess the efficacy and safety of letrozole in combination with afatinib(oral epidermal growth factor receptor (EGFR ) inhibitor) versus letrozole monotherapy for the first-line treatment of postmenopausal women with ER+, Human Epidermal Growth Factor Receptor 2 (HER2) negative advanced breast cancer with low ER expression.
In order to assess the level of estrogen receptor (ER) expression we will use a semi-quantitative scoring system (McClelland, 1990) defined as :
H-score = (% of cells stained at intensity category 1x1) + (% of cells stained at intensity category 2x2) + (% of cells stained at intensity category 3x3).
This formula results in an H-score in the range of 0-300 where 300 equals 100% of tumor cells stained strongly (i.e., 3+). Low ER expression will be defined as tumor sample with H-score below 160 (Finn, 2009).
All subjects who consented for the study must submit a tumor sample to the designated central laboratory for central confirmation of ER / Progesterone receptor (PR) and HER2 statuses and determination of the H-score. This will be assessed prior to randomization.
Subjects with HER2 negative, ER+ advanced breast cancer with low ER expression defined as H-score between 1 and 159 will enter screening phase and perform the required screening assessments.
Eligible subjects will be randomly assigned in a 1:1 ratio and stratified according to sites of disease (bone only disease vs. other) and prior administration of hormonal therapy in neo/adjuvant setting (Yes vs. No) to either:
Arm A : Continuous regimen of oral letrozole 2.5 mg until progression of disease or any other study treatment discontinuation criteria.
or Arm B : Continuous regimen of oral letrozole 2.5 mg daily plus oral afatinib 30 mg daily until progression of disease or any other study treatment discontinuation criteria.
IN ADDITION the following applies whichever comes first:
- If the patients treated with the combination of afatinib and letrozole (arm B) discontinue the trial treatment (whatever the reason) before 30 November 2018, the patients from the other arm (arm A, letrozole alone) still on treatment will also be discontinued from the trial at the same time. They may continue receiving letrozole using commercial drug as standard of care according to their treating physician discretion.
- If the patients treated with afatinib and letrozole (arm B) have not discontinued the trial treatment by 30 November 2018, all patients currently on treatment in the trial (including the ones only treated by letrozole alone (arm A)) will be discontinued from the trial at that time. They may continue receiving their treatment if in alignment with their treating physician judgment as follows:
- Patients in arm A: may continue receiving letrozole using commercial drug as standard of care according to their treating physician discretion.
- Patients in arm B: may continue receiving afatinib in the context of alternative drug supply outside the clinical trial as appropriate according to local legislation. Additionally, they may continue receiving letrozole using commercial drug as standard of care according to their treating physician discretion.
Once the patient is discontinued from trial treatment and has undergone the End of Treatment Visit, she will be permanently discontinued from the trial and treated as per local clinical practice.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
LetrozoleDrug
AfatinibDrug
| Study group | Role | What they receive |
|---|---|---|
| Arm A | Active comparator | Continuous regimen of oral Letrozole 2.5 mg daily Receives: Drug: Letrozole |
| Arm B | Experimental | Continuous regimen of oral Letrozole 2.5 mg daily plus oral Afatinib 30 mg daily Receives: Drug: Letrozole; Drug: Afatinib |
What is being measured
The primary outcome is the main question the study is designed to answer.
Progression Free Survival (PFS)
Progression Free Survival (PFS) is defined as the time from randomization until date of progression (assessed by Response Evaluation Criteria in Solid Tumors - RECIST) or death due to any cause, whichever occurs first. For evaluation of PFS, the randomization date for each patient was the "start date". If the status at the last assessment date was "Non-complete response/ Non-progressive disease" or "Complete response", then the patient was considered "censored". If the status at the last assessment for any tumor was "Progressive disease", then the patient was considered as having an event.
Progressive disease is defined using RECIST v1 .1 as a ≥ 20% increase in the sum of the longest diameter of target lesions compared with the smallest-sum longest diameter recorded or the appearance of one or more target or non-target new lesions and/or unequivocal progression of existing non-target lesions.
Measured: Tumor assessments were every 12 weeks up to 9 months (average) for subjects in Arm A or up to 14 months (average) for subjects in Arm B.
Secondary outcomes (4)
Overall Survival (OS)
Overall Survival is defined as the time from randomization until death to any cause.
For subjects in which treatment is discontinued for reasons different than Progression Disease: after treatment and up to documentation of disease progression: Overall Survival is assessed every 12 weeks
Measured: Under treatment: every 4 wks up to 9 months (average) for subject in the Arm A or up to 14 months (average) for subjects in Arm B. After documentation of disease progression up to the end of the study: every 6 months up to 42 months
Objective Response Rate (ORR)
Objective response rate (ORR) is defined as the proportion of randomized subjects achieving a best overall response of complete response (CR) or partial response (PR) as per Response Evaluation Criteria In Solid Tumors (RECIST). As per RECIST (version 1.1):
CR is defined as disappearance of all target and non target lesions - lymph node (LN) <10mm.
PR is defined as at least a 30% decrease in the Sum of Diameters, taking as reference the Baseline Sum of Diameters
Measured: Tumor assessment: every 12 weeks up to 9 months (average) for subjects in Arm A or up to 14 months (average) for subjects in Arm B.
Time to Tumor Progression (TTP)
As per Response Evaluation Criteria In Solid Tumors (RECIST). Time to progression (TTP) is defined as the time interval from date of randomization to date of the first documented objective tumor progression.
Measured: Tumor assessments: every 12 weeks up to 9 months (average) for subjects in Arm A or up to 14 months (average) for subjects in Arm B.
Number of Participants With Adverse Events
Participants who experienced at least one Treatment Emergent Adverse Event (TEAE) are presented. Participants with at least one serious TEAE, those who had at least one TEAE related to letrozole or afatinib (serious/non-serious), including participants who experienced a grade 3/4 TEAE, or who discontinued/died as a result of their TEAE are listed by treatment arm. Adverse events were tabulated by system organ class, preferred term and toxicity grade by treatment arm. For subjects in which treatment was discontinued for reasons different than progression of disease, the assessment was conducted every 12 weeks following treatment, and up to documentation of disease progression.
** Enrollment was closed prematurely due to low recruitment (only 44 participants enrolled) compared to what was initially planned (150 participants), therefore no statistical evaluations were completed. Adverse event data collected are described per arm but no statistical comparison was made.
Measured: Under treatment: every 4 wks up to 9 months (average) for subjects in Arm A or up to 14 months (average) for subjects in Arm B. After documentation of disease progression up to the end of the study: every 6 months up to 42 months

A Phase 2 study testing Letrozole and Afatinib in people with Breast Neoplasms, run by Translational Research in Oncology at 26 sites in 4 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 11 inclusion and 18 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 26 Dec 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 26 sites in United States, Spain, Romania, Bosnia and Herzegovina. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 26 Dec 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Progression Free Survival (PFS) (time frame: Tumor assessments were every 12 weeks up to 9 months (average) for subjects in Arm A or up to 14 months (average) for subjects in Arm B.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Dec 2019.
