Phase I Hu3F8-BsAb is given IV over ~1-3 hours on Days 1 and 8 for each cycle. In cycle 1, blood is drawn for PK studies.Phase II Hu3F8-BsAb is given IV over ~1-3 hours on Days 1 and 8 for each cycle.
Biological: Humanized 3F8 Bispecific Antibody
Phase I Hu3F8-BsAb is given IV over ~1-3 hours on Days 1 and 8 for each cycle.Phase II Hu3F8-BsAb is given IV over ~1-3 hours on Days 1 and 8 for each cycle.
Other Name: Humanized 3F8 Bispecific Antibody (Hu3F8-BsAb)
Other: Blood draw
In cycle 1, blood is drawn for PK studies.
- maximum tolerated dosage (MTD) Phase I [ Time Frame: Days 1 through 28 ]The MTD will be defined as the dose whose toxicity rate does not exceed an acceptable threshold of toxicity of 15%.Toxicity will be monitored using CTCAE version 4.0. DLT only during cycle 1, i.e. Days 1 through 28. Allowance will be made for the expected toxicities of hu3F8 from which hu3F8-BsAb was derived.
