Phase I/II Study of hLL1-DOX in Relapsed NHL and CLL

• Status: Terminated
• Trial end date: 2017-10-01
• Target enrollment: 0
• Participant gender: All

Summary

The primary objectives are to evaluate the safety and tolerability of hLL1-DOX, and to determine the maximum tolerated dose (MTD) regimen (in terms of a dose and its associated dosing schedule). The secondary objectives are to obtain information on efficacy, pharmacodynamics, pharmacokinetics, and immunogenicity, and to determine the optimal dose for subsequent studies.

• Phase: Phase 1/Phase 2
• Accepts Healthy Volunteers?: No

• Lead Sponsor: Gilead Sciences; Immunomedics, Inc.
