Phase I Study to Evaluate Safety and Anti-tumor Activity of PB101, an Anti-angiogenic Immunomodulating Agent

"Cohorts of 3-6 patients receive PB101 until the MTD is determined. The dose (2 mg/kg-15 mg/kg) assigned to the cohort will be administered weekly for two 28-day cycles or until progressive disease (PD), unacceptable toxicity, withdrawal of subject consent, and/or the investigator's decision to discontinue the study treatment occurs.~Administration may be continued for subjects in whom PB101 provides clinical benefits at the discretion of the investigator."
