Study Summary

This trial is testing a new cancer treatment that involves delivering genetically-modified T cells into the brain. The goal is to find the best dose and to assess side effects.

Eligible Conditions
  • HER2-positive Breast Cancer
  • Cancer
  • Breast Cancer

Eligibility Criteria

Age 18 - 75 · All Participants · 10 Total Inclusion Criteria

Mark “Yes” if the following statements are true for you:
Participants who have had brain and/or leptomeningeal metastases that have not recurred are eligible to enroll in the study, but they cannot start treatment with HER2-CAR T cells until there is evidence of tumor progression/recurrence.
for the diagnosis of leptomeningeal metastasis Individuals who have been diagnosed with leptomeningeal metastasis may also have brain metastases, but this is not always the case
A person is eligible to have leukapheresis if at least 2 weeks have passed since their last dose of targeted agents, chemotherapy, or radiation
The participant has a cancer that is classified as HER2+ based on the results of an IHC test or a FISH test.
Participants must be able to understand and sign a written informed consent.
You are eligible to proceed with leukapheresis if you do not require more than 6 mg/day of dexamethasone (or the equivalent dose of another corticosteroid) on the day of leukapheresis.
The subject has either recurrent leptomeningeal metastases after intrathecal chemotherapy or untreated brain or leptomeningeal metastases and refuses to undergo radiation and/or intrathecal chemotherapy.
Screening for this study will require a Karnofsky performance status of at least 70.
The participant must have a life expectancy of at least eight weeks in order to participate.
