Efficacy Study of Pharmacokinetic(PK)/Pharmacodynamic(PD) Relationship of Monotherapy MORAb-004 in Metastatic Melanoma


Metastatic Melanoma

Trial Phase

Phase 2

Trial Purpose and Description

Trial Purpose

This is a global, Phase 2, open label, dose selection, proof-of-concept study to assess progression free survival in subjects with metastatic melanoma.

80+ subjects at 29 sites in the U.S., U.K., Germany and Australia will be randomized into one of two dose groups: 2 mg/kg, 4 mg/kg. Weekly treatment will continue until disease progression.

Subjects must have measurable disease by CT Scan or MRI and must have completed at least one prior round of chemotherapy.

Subjects will be assessed for Efficacy, PK/PD, Overall survival, and Safety (Adverse Events/Adverse Events of Interest, Electrocardiograms (ECG's), clinical labs, physical exams/vital signs, tolerability).

Trial Description

MORAb-004 is a monoclonal antibody directed against endosialin, a cell surface glycoprotein, which is expressed on cells involved in tumor vasculature. Studies have found endosialin to play a key role in tumor growth and neovessel formation in numerous cancer types including melanoma. Preclinical pharmacological studies have shown that MORAb-004 is a potentially useful anti-cancer agent. This clinical trial is being performed to determine the efficacy of MORAb-004 at two dose levels in subjects with metastatic melanoma, as well as to establish serum pharmacokinetics and pharmacodynamics of the antibody.
