  • Subjects must not have received more than 1 prior chemotherapeutic regimen in the metastatic setting.
  • All prior chemotherapy, immunotherapy, biologic therapy, or surgery (except for minor surgical procedures) must be discontinued at least 4 weeks prior to first dose of investigational product. Hormonal therapy must be discontinued at least 1 week prior to first dose.
  • Prior diagnosis of cancer is allowed as long as the subject is free of disease and has been off treatment for prior malignancies for 5 years. Subjects with completely resected basal or squamous cell skin cancer or successfully treated cervical carcinoma in situ will be allowed if it has been 1 year or longer since definitive surgery.
  • Subjects must have measurable disease, according to Response Evaluation Criteria in Solid Tumors (RECIST) guidelines.
  • Females aged ≥18 years with any menopausal status:
  • Non-child-bearing potential (i.e., women with functioning ovaries who have a current documented tubal ligation or hysterectomy, or women who are postmenopausal)
  • Child-bearing potential (i.e., women with functioning ovaries and no documented impairment of oviductal or uterine function that would cause sterility): This category includes women with oligomenorrhea (severe), women who are perimenopausal, and young women who have begun to menstruate. These subjects must have a negative serum pregnancy test at screening and agree to one of the following:
  • Complete abstinence from intercourse from 2 weeks prior to administration of the first dose of study medication until 28 days after the final dose of study medication; or
  • Consistent and correct use of one of the following acceptable methods of birth control: male partner who is sterile prior to the female subject's entry into the study and is the sole sexual partner for that female subject; any intrauterine device with a documented failure rate of less than 1% per year; oral contraceptives (either combined or progestogen only) where not contraindicated for this subject population or per local practice.; or barrier methods, including diaphragm or condom with a spermicide.

About this study

Official title: A Phase II, Single-Arm, Multi-Center Study Evaluating the Combination of Vinorelbine and Lapatinib in Women With ErbB2 Overexpressing Metastatic Breast Cancer

This is an open-label, single-arm, multi-center, Phase II study to determine the activity of vinorelbine plus lapatinib in either first- or second-line setting in women with ErbB2 overexpressing metastatic breast cancer (MBC). Sixty subjects will be enrolled in the study. Subjects will receive vinorelbine intravenously once weekly for 3 weeks, followed by a rest week in a 4-week cycle) plus lapatinib daily. Subjects will receive treatment until disease progression or withdrawal from the study. The primary objective of this study is to evaluate overall tumor response rate of lapatinib in combination with vinorelbine. Secondary objectives include progression-free survival, overall survival, duration of response, time to response and time to progression and safety. Safety and efficacy assessments will be performed at 4, 8 and 12 week intervals, and at the end of treatment.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Lapatinib, VinorelbineDrug

    Also called Lapatinib, Vinorelbine

    Vinorelbine intravenously once weekly for 3 weeks, followed by a rest week in a 4-week cycle) plus lapatinib daily

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With Overall Response (OR), as Assessed by the Investigator

    OR is defined as the number of participants achieving either a confirmed complete response (CR: the disappearance of all target lesions [TLs]) or partial response (PR: a >=30% decrease in the sum of the longest diameter [LD] of the TLs, taking as a reference the baseline sum LD) as assessed by the investigator as the best OR. The best OR is the best response recorded from the start of treatment until disease progression (PD: a >=20% increase in the sum of the LD of TLs, taking as a reference the smallest sum LD recorded since treatment started or the appearance of >=1 new lesions)/recurrence.

    Measured: From the start of study medication until disease progression, assessed every 8 weeks for up to 2 years

Secondary outcomes (6)

  1. Progression-Free Survival (PFS), as Assessed by the Investigator

    PFS is defined as the time from the start of treatment until the earliest date of disease progression (PD) or death due to any cause, if sooner. PD is defined as at least a 20% increase in the sum of the LD of target lesions, taking as a reference the smallest sum LD recorded since the treatment started or the appearance of 1 or more new lesions.

    Measured: From the start of study medication until disease progression, assessed every 8 weeks for up to 2 years

  2. Duration of Response, as Assessed by the Investigator

    Duration of response, for the subset of participants who had a confirmed CR (the disappearance of all TLs) or PR (a >=30% decrease in the sum of the LD of the TLs, taking as a reference the baseline sum LD), is defined as the time from the first documented evidence of CR or PR until the first documented sign of disease progression (a >=20% increase in the sum of the LD of TLs, taking as a reference the smallest LD recorded since treatment started or the appearance of >=1 new lesions) or death due to any cause, if sooner.

    Measured: From the start of study medication until disease progression, assessed every 8 weeks for up to 2 years

  3. Time to Response, as Assessed by the Investigator

    Time to response, for the subset of participants who had a confirmed CR (the disappearance of all TLs) or PR (a >=30% decrease in the sum of the LD of the TLs, taking as a reference the baseline sum LD), is defined as the time from the start of treatment until the first documented evidence of CR or PR (whichever status was recorded first). When tumor response was confirmed at a repeat assessment, the time to response was taken to be the first time that the response was observed.

    Measured: From the start of study medication until disease progression, assessed every 8 weeks for up to 2 years

  4. Time to Progression (TTP), as Assessed by the Investigator

    TTP is defined as the time from the start of treatment until the earliest date of disease progression (a >=20% increase in the sum of the LD of TLs, taking as a reference the smallest LD recorded since treatment started or the appearance of >=1 new lesions) or death due to breast cancer, if sooner.

    Measured: From the start of study medication until disease progression, assessed every 8 weeks for up to 2 years

  5. Number of Participants With the Indicated Adverse Events Occurring in at Least 5 Participants and Related to the Combination of Lapatinib and Vinorelbine

    Qualitative and quantitative toxicities associated with the combination of lapatinib and vinorelbine during the study are those adverse events (AEs) that are judged to be related to the study treatment by the investigator. Those AEs occuring in more than 5 participants in the ITT Population are listed here.

    Measured: From the start of study medication until disease progression, assessed every 4 weeks for up to 2 years

  6. Overall Survival

    OS is defined as the time from the start of study treatment to the date of death. In the absence of confirmation of death, survival time was to be censored at the last date the participant was known to be alive. Overall survival was not assessed because the study was terminated due to low screening and a low enrollment rate after 3 years. There were no-survival follow-up visits required.

    Measured: From the start of study treatment to the date of death, assessed for up to 3 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Lapatinib, Vinorelbine in people with Neoplasms, Breast, run by GlaxoSmithKline at 22 sites in United States.

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 30 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 14 Jul 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 22 sites in United States. 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 18 Jan 2013). 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?

Number of Participants With Overall Response (OR), as Assessed by the Investigator (time frame: From the start of study medication until disease progression, assessed every 8 weeks for up to 2 years). 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 NCT00709618.

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 14 Jul 2014.
