---|---|
Experimental: 2B3-101 Single Agent Dose Escalation
Patients in single agent dose escalation arm will receive a single IV dose of 2B3-101 on day 1 of each cycle. In order to minimize the risk of infusion reactions 5% of the total dose of 2B3-101 (in mg) should be infused slowly 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
IV every 21 days
Other Name: Glutathione pegylated liposomal doxorubicin hydrochloride |
Experimental: 2B3-101 in combination with trastuzumab
HER2+ breast cancer patients with brain metastases will receive a single IV dose of 2B3-101 on day 1 of each cycle. In order to minimize the risk of infusion reactions 5% of the total dose of 2B3-101 (in mg) should be infused slowly over the first 30 minutes. As long as 2B3-101 is well tolerated, the remaining 95% of the infusion could thereafter be administered over the next 60 min, resulting in a total infusion time of 90 minutes. The infusion of trastuzumab will then follow 30 minutes after the completion of the 2B3-101 infusion.
