Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 18 years and older
- Women only
- No healthy volunteers
- Adult, Older adult
Who may be able to join
- Signed informed consent.
- Female ≥18 years. Women of childbearing potential must have a negative serum pregnancy test at screening and must use an approved contraceptive method, if appropriate (for example, intrauterine device [IUD], birth control pills, or barrier device) beginning 2 weeks before the first dose of investigational product and for 28 days after the final dose of investigational product.
- Metastatic breast cancer, histologically/cytologically confirmed. If the disease is restricted to a solitary lesion, its neoplastic nature must be confirmed by cytology or histology.
- Subjects must have stage IV breast cancer whereby their disease has progressed in either the adjuvant or metastatic setting. Prior therapies must include, but are not limited to:
- Taxane-containing regimen for at least 4 cycles, or 2 cycles provided disease progression occurred while on taxane.
- Anthracycline-containing regimen for at least 4 cycles, or 2 cycles provided disease progression occurred while on anthracycline.

- Subjects must have documented progression following at least ONE trastuzumab plus cytotoxic chemotherapy or anti-hormonal regimen in the metastatic setting.
- Note: The most recent treatment must have contained trastuzumab, either alone or in combination with other therapy in the metastatic setting, and subjects must have progressed while on this regimen. Progression is defined as either new lesions or a ≥20% increase in the sum of longest diameter (LD) on the progression radiologic scan.
- Subjects must have archived tumor tissue available for testing.
- Documented amplification of the ErbB2 gene by fluorescence in situ hybridization (FISH) or documented overexpression of the ErbB2 protein by IHC in primary or metastatic tumor tissue. The IHC or FISH amplification may be documented by a local or central laboratory for randomization into the study. Subjects may be randomized on the basis of ErbB2 positivity by IHC 3+ overexpression or FISH amplification.
- Lesion eligibility is as follows:
- at least one measurable lesion(s) according to Response Evaluation Criteria in Solid Tumors [RECIST; Therasse, 2000], or
- bone-only disease.
- Note: Tumor lesions which are situated in a previously irradiated field, and have well-defined margins which are located in soft tissue will be defined as measurable disease.
- Subjects with stable CNS metastases defined as asymptomatic and off systemic steroids and anticonvulsants for at least 1 month. Treatment with prophylactic anticonvulsants is permitted, unless listed within the Prohibited Medications (Section 8.2).
- Radiotherapy if received within 2 weeks prior to initiation of investigational product to a limited area (e.g., palliative treatment for painful disease) other than the sole site of measurable disease is allowed; however, subject must have completed treatment and recovered from all treatment-related toxicities prior to administration of the first dose of investigational product.
- With the single exception of prior trastuzumab treatment, all prior chemotherapy, immunotherapy, biologic therapy, or surgery (except for minor surgical procedures) must be discontinued at least 3 weeks prior to the first dose of investigational product. Subjects must have recovered or stabilized sufficiently from treatment-related toxicities prior to administration of the first dose of investigational product.
- Bisphosphonate therapy for bone metastases is allowed; however, treatment must be initiated prior to the first dose of investigational product. Prophylactic use of bisphosphonates is permitted only for the treatment of osteoporosis.
- ECOG Performance Status of 0 to 2.
- Able to swallow and retain oral medication.
- Cardiac ejection fraction within institutional range of normal as measured by echocardiogram. MUGA scans will be accepted in cases where an echocardiogram cannot be performed or is inconclusive. Same modality used at baseline must be used for repeat assessments throughout study.
- Subject must have adequate organ function as defined in Table 1 :

oral lapatinib once daily
TrastuzumabBiological
Also called Herceptin
IV trastuzumab 2mg/kg weekly after 4mg/kg loading dose
| Study group | Role | What they receive |
|---|---|---|
| Arm 1: Lapatinib plus Trastuzumab | Experimental | Lapatinib 1000mg once daily in combination with trastuzumab 4mg/kg loading dose followed by 2mg/kg weekly Receives: Drug: Lapatinib; Biological: Trastuzumab |
| Arm 2: Lapatinib | Experimental | Lapatinib 1500mg once daily Receives: Drug: Lapatinib |
What is being measured
The primary outcome is the main question the study is designed to answer.
Progression-Free Survival (PFS)
PFS was defined as the time from randomization until the first documented sign of disease progression or death due to any cause.
Measured: Baseline to disease progression or death due to any cause or 30 days after last dose (up to 216 weeks)
Secondary outcomes (7)
Overall Survival (OS)
OS was defined as the time from randomization until death due to any cause. For participants who did not die, OS was censored at the time of last contact.
Measured: Baseline to death or 30 days after last dose for the last participant (up to 216 weeks)
Overall Tumor Response (OR)
OR was defined as the percentage of participants experiencing either a confirmed complete response (CR) or a confirmed partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST) criteria 1.0. CR was defined as the disappearance of all lesions (target and/or non-target). PR was defined as at least a 30% decrease in the sum of the longest dimensions (LD) of target lesions taking as a reference the baseline sum LD, with non-target lesions not increased or absent.
Measured: Baseline to disease progression or death or discontinuation from study or 30 days after last dose (up to 216 weeks)
Clinical Benefit Response (CBR)
CBR: percentage of participants with confirmed CR or PR or stable disease (SD) for at least 24 weeks according to RECIST criteria. CR: disappearance of all lesions (target and/or non-target). PR: at least a 30% decrease in the sum of the LD of target lesions taking as reference baseline sum LD, with non-target lesions not increased or absent. SD: neither had sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD) in target lesions, taking as reference the smallest sum LD since treatment started; persistence of 1 or more non-target lesions.
Measured: Baseline to disease progression or death or discontinuation from study or 30 days after last dose (up to 216 weeks)
Time to Response (TTR)
TTR was defined as the time from randomization until the first documented evidence of CR or PR (whichever status was recorded first). TTR could not be analyzed because too few participants experienced a confirmed CR or PR.
Measured: Baseline until first documented evidence of CR or PR or 30 days after last dose (up to 216 weeks)
Duration of Response (DR)
DR was defined for the subset of participants who showed a confirmed CR or PR, as the time from the first documented evidence of CR or PR until the first documented sign of disease progression or death. Because of the low number of participants experiencing a confirmed response in both treatment arms, analysis for this outcome measure was not performed.
Measured: Time from first documented evidence of CR or PR until the first documented sign of disease progression or death or 30 days after last dose (up to 216 weeks)
Time to Progression (TTP)
TTP was defined as the interval between the date of randomization and the earlier of the date of disease progression or death due to breast cancer. Because this outcome measure was confounded by death due to other causes and was similar to PFS, it was not analyzed.
Measured: Baseline to disease progression or death or 30 days after last dose (up to 216 weeks)
Change From Baseline in Functional Assessment of Cancer Therapy-Breast (FACT-B) Scores at Week 4, Week 12, Week 16, Week 24, and Conclusion or Withdrawal From Study
Quality of Life (QOL) was assessed using the FACT-B questionnaire, which was a 37-item (27 general and 10 breast cancer-specific questions) self-reporting instrument consisting of 5 dimensions: physical-, social/family-, emotional-, functional-well being, and a breast cancer subscale. Higher scores on the FACT-B scales indicate a higher QOL; each ranging from 0 (not at all) to 4 (very much). The score is transformed for FACT-B and results in a total score ranging from 0 to 144.
Measured: Baseline, Week 4, Week 12, Week 16, Week 24, and conclusion or withdrawal from study (up to Week 108)

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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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 30 Nov 2011). 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: Baseline to disease progression or death due to any cause or 30 days after last dose (up to 216 weeks)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00320385, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
