Safety Study of MGA271 in Refractory Cancer
The purpose of this study is to evaluate the safety of MGA271 when given by intravenous (IV) infusion to patients with refractory cancer. The study will also evaluate how long MGA271 stays in the blood and how long it takes for it to leave the body, what is the highest dose that can safely be given, and whether it may have an effect on tumors.

Fc-optimized, humanized monoclonal antibody
Up to 9 dose escalation cohorts will be enrolled to determine the maximum tolerated dose of MGA271. Patients with evidence of clinical benefit will be allowed to continue therapy at the same dose once per week for 3 weeks out of every 4-week cycle until documented progression.
An open-label, multi-dose, single-arm, multi-center, Phase 1, dose-escalation study will be conducted to define the toxicity profile, maximum tolerated dose (MTD), pharmacokinetics (PK), immunogenicity, and potential antitumor activity of MGA271 in patients with refractory cancer that expresses B7-H3.
Patients will be monitored for a minimum of four weeks after administration of the final dose of MGA271. Study assessments will include adverse event (AE) monitoring, electrocardiogram (ECG) monitoring, PK analysis of serum MGA271, determination of the serum concentration of soluble MGA271 and tumor markers, and an assessment of potential anti-MGA271 antibody [human anti-human antibody (HAHA)] response.
Tumor response assessments using Study Day 43 CT scans or MRI will be performed approximately six weeks after the first MGA271 dose for each patient. Patients with evidence of clinical benefit (partial or complete response or stable disease by RECIST or RANO Response criteria) will be allowed to continue therapy at the same dose, or at a reduced dose if warranted by dose limiting toxicity (DLT) or significant AE in Cycle 1. Subsequent cycles which will begin on Study Day 50 will consist of MGA271 administration on Study Days 1, 8, and 15 of each 28-day cycle, with tumor evaluation every other cycle. Responding patients may receive continued antibody therapy until evidence of progression of disease is documented or the patient experiences DLT.
