About this study

Official title: Phase Ib Study of Preoperative Chemotherapy With Paclitaxel, Gemcitabine, and Lapatinib (Tykerb®) (PGT) in Patients With HER2 Positive Operable Breast Cancer

Primary objectives :

  1. To evaluate the recommended dose of the combination of paclitaxel, gemcitabine, and lapatinib (Tykerb®) (PGT) as preoperative chemotherapy in patients with HER2 positive operable breast cancer

Secondary objectives :

  1. To evaluate the maximum tolerated dose (MTD) and dose-limiting toxicity (DLT) of PGT
  2. To determine the safety profile
  3. To assess pCR in primary tumor and axillary LN
  4. To evaluate clinical response rate, disease free survival (DFS), and overall survival (OS)
  5. To assess breast conserving rate after preoperative PGT
Read the detailed description

Unlike adjuvant chemotherapy, primary (preoperative) chemotherapy will shrink tumor and allow some patients to become candidates for conservative surgery and avoid mastectomy. It also is an in vivo chemosensitivity test and the result is a predictive marker for clinical outcomes. Paclitaxel is a highly active antitumor agent that promotes microtubule assembly by binding to tubulin and inhibiting depolymerization. Paclitaxel has been shown to be an effective agent in the treatment of breast cancer. Gemcitabine is a cytosine arabinoside prodrug analog and shows response rates of 15% to 46% as a single agent with very low toxicity. The combination of gemcitabine and paclitaxel is valuable because of the different mechanisms of action of each drug and their non-overlapping toxicities. Phase II studies of paclitaxel plus gemcitabine in anthracycline-pretreated metastatic breast cancer showed good tolerance and encouraging response rates (40%-55%). Paclitaxel plus gemcitabine combination showed overall survival benefit compared to paclitaxel alone in patients with metastatic breast cancer in an interim overall survival report. A phase II study with preoperative paclitaxel and gemcitabine in stage II/III showed 18 % pCR rate at NCC (ASCO 2007 abstract #11080) In HER2 positive breast cancer, HER2 targeted therapies with trastuzumab and lapatinib have shown much improved clinical response in palliative setting. It also showed that adding trastuzumab to sequential paclitaxel and FEC chemotherapy significantly increased pCR (25% vs 66.7%) in preoperative setting for HER2 positive disease. Recently, paclitaxel, gemcitabine, and trastuzumab combination (PGH) for 6 cycles in patients with HER2 positive and node positive operable breast cancer observed a strikingly high pCR rate in both tumor and LN in an interim analysis of multicenter phase II preoperative study in Korea (28 of 47 (61%)). Lapatinib (Tykerb®), a dual tyrosine kinase inhibitor of ErbB1 and HER2 signaling pathways and it has shown to inhibit the growth of HER2 overexpressing breast cancer cells that do not respond to trastuzumab after long-term conditioning. We will examine the hypothesis that paclitaxel, gemcitabine, and lapatinib (Tykerb®) (PGT) combination could improve the pathological complete response rate of HER2 positive breast cancer when applied as a preoperative chemotherapy.

What participants receive

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

  • paclitaxel, gemcitabine, lapatinibDrug

    Also called Paclitaxel, Gemzar, Tykerb

    Patients receive paclitaxel and gemcitabine intravenously (iv) on day 1 and 8, and oral lapatinib once daily. Lapatinib with fixed dose will be given once a day p.o. from day 1 without resting during each cycle. The starting doses of paclitaxel 80mg/m2 and gemcitabine 1000mg/m2 iv, on day 1 and 8, and lapatinib 1000mg p.o., daily (dose level 1) will be administered every 21 days.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing paclitaxel, gemcitabine, lapatinib in people with Breast Cancer, run by Jungsil Ro at 1 site in South Korea.

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 17 inclusion and 7 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: finished, as of the sponsor's last update on 4 Jan 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

To evaluate the recommended dose of the combination of paclitaxel, gemcitabine, and lapatinib (Tykerb®) (PGT) as preoperative chemotherapy in patients with HER2 positive operable breast cancer (time frame: two years). 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 4 Jan 2012.
