Brief Summary

Leptomeningeal metastases (LM) develop when tumor cells reach the cerebrospinal fluid (CSF) and infiltrate the leptomeninges. The median survival of patient with breast cancer and LM is 4-6 months with up to 25% long-term survivors. Many potentially highly efficacious intravenous chemotherapies are currently not effective to treat LM because they do not adequately cross the blood-CSF barrier. Doxorubicin, the anthracycline chemotherapeutic agent, has a well-established antineoplastic activity in breast cancer. To optimally enhance the delivery of liposomal doxorubicin to the brain, to-BBB technologies B.V. has designed a glutathione (GSH) pegylated liposomal doxorubicin hydrochloride formulation (2B3-101). Coating of liposomes with PEG ensures the prolonged circulation time in plasma, whilst conjugation of GSH to the tips of the PEG molecules targets the liposomes towards the active GSH transporters on the BBB to enhance the delivery of doxorubicin to the brain. This is a a clinical and pharmacological study that aims to determine preliminary efficacy of treatment with 2B3-101 in patients with leptomeningeal metastases of breast cancer using the LM response score.

Outcome Measures

Primary Outcomes (1)

  • - safety and preliminary response using the "LM response score" during the 2B3-101 treatment in patients with LM from breast cancer.

    All adverse events will be collected during the safety visits and summarized during the analysis using descriptive statistics. The data reported every 2 cycles by de radiologist (MRI reports), pathologist (CSF cytology) and neurologist (clinical response) will be compared using specially designed "LM response score" for this study.

    one year

Secondary Outcomes (6)

  • - CNS progression free survival in patients with LM from breast cancer treated with 2B3-101.

    one year

  • - collecting clinical and radiological findings (MRI) and CSF cytology and comparing them with doxorubicin levels in CSF and in plasma during the treatment of patients with LM from breast cancer with 2B3-101.

    one year

  • - systemic progression free survival in patients with LM from breast cancer treated with 2B3-101.

    one year

  • overall survival in patients with LM from breast cancer treated with 2B3-101.

    one year

  • - the change in number of CTCs in CSF and blood and its correlation with the LM response score.

    one year

  • +1 more secondary outcomes

Study Arms (1)

2B3-101

EXPERIMENTAL

A single dose of 2B3-101 (a glutathione (GSH) pegylated liposomal doxorubicin hydrochloride formulation) will be administrated intravenously once per cycle. To minimize the risk of infusion reactions, 5% of the total dose of 2B3-101 (in mg) will be administrated over the first 30 minutes. If tolerated, the infusion may then be completed over the next hour for a total infusion time of 90 minutes

Drug: 2B3-101

Interventions

50 mg/m2 2B3-101 intravenous 3-weekly administration

Also known as: glutathione pegylated liposomal doxorubicin
2B3-101
