United States34 participantsStarted 2011-08-01

Plain-language summary

The drug being studied is Trastuzumab, a medicine that is used to slow or stop the growth of cancerous tumors that are HER-2 positive. Patients are being asked to participate in this study because they have been diagnosed with having tumor cells in their spinal fluid. This study will investigate the safety and effects of this drug when given directly into the spinal fluid. Phase I/II Dose Escalation Trial to Assess Safety of Intrathecal Trastuzumab for the Treatment of Leptomeningeal Metastases in HER2 Positive Breast Cancer The purpose of this research study is to determine a safe dose of the drug Trastuzumab and then determine how effective this treatment is.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: ELIGIBILITY CRITERIA * HER2 positive (IHC 3+ and/or FISH positive) breast cancer patients with leptomeningeal metastases by MRI or CSF (if MRI is negative). o Review will be performed for cases not reviewed at Northwestern for confirmation, but will not preclude patients from entering the trial (pathology report is sufficient for registration). * Patients can have concomitant brain metastases as long as they do not require active treatment or have been treated. * Patients with leptomeningeal disease from ependymomas, gliomas, and medulloblastoma will be eligible for phase I * Life expectancy \> 8 weeks * Normal renal (creatinine \< 1.5 ULN), liver (bilirubin \< 1.5 x ULN, transaminases \< 3.0 x ULN, except in known hepatic metastasis, wherein may be \< 5 x ULN) and blood counts (WBC \> 3.0, Neutrophils \> 1500, platelets \>100 000, Hemoglobin \> 10). * LVEF \> 50% * KPS \> 50 * Age \> 18 years * Cannot be on systemic agents (chemotherapy) that have CNS penetration unless they develop leptomeningeal metastases while on these agent(s) and have controlled systemic disease. May continue on IV trastuzumab, lapatinib or hormonal agents if controlling systemic disease and developed LM while on therapy. Patients requiring systemic chemotherapy are eligible but will not be able to start treatment until after the first assessment by imaging and cytology. * Patients may need a CSF flow study at the discretion of the treating principal investigator.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

Number of Dose Limiting Toxicities (DLT) of IT Trastuzumab in Sequential Cohorts of Escalating Doses for Patients With Leptomeningeal Metastases in HER2+ Breast Cancer.

Timeframe: From treatment initiation through the first 4 weeks of treatment.

Best Response to IT Trastuzumab: Radiological, Cytological and Clinical in Treatment With Intrathecal Trastuzumab for Patients With Leptomeningeal Metastases in HER2+ Breast Cancer.

Timeframe: Baseline then at 4 weeks, 8 weeks and then every 8 weeks +/- 3 days, until disease progression or toxicity,range of cycles completed 1-22 cycles where 1 cycle = 28 days.
