Study Evaluating CMD-193 in Advanced Malignant Solid Tumors

A Phase 1 Dose Escalation Study of CMD-193 in Subjects With Advanced Malignant Tumors.

The purpose of this study is to determine the safety, tolerability and maximum tolerated dose of CMD-193. Preliminary information about how a person's body processes CMD-193 and how CMD-193 affects tumors will also be collected.

Inclusion Criteria:

• Histologically confirmed malignant solid tumor that has progressed following standard therapy, or for which no standard effective treatment is available
• Tumor expression of Lewis Y antigen ( > or = 20% tumor cells positive for Lewis Y by immunohistochemistry assay)
• Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1

Exclusion Criteria:

• Chemotherapy, radiation therapy, other cancer therapy, or investigational agents within 21 days of the first dose of CMD-193 (42 days if the previous chemotherapy included nitrosoureas or mitomycin C)
• Symptomatic or clinically active CNS metastases. Subjects who have had prior treatment with radiotherapy or surgical resection for CNS metastases will be permitted if CNS metastases have remained stable and have not required any treatment for at least 3 months prior to the first dose of CMD-193.
• Significant prior allergic reaction to recombinant human or murine proteins
