Clinical Trial Summary

This is a Phase I/II, open-label, multi-center study conducted in patients with recurrent or refractory multiple myeloma who have failed at least two prior standard systemic treatments.

Description:

All patients receive hLL1 administered intravenously twice weekly for 4 consecutive weeks. Cohorts of 3-6 patients will receive escalating doses of hLL1 in order to determine the maximum tolerated dose (MTD) for this administration schedule. Up to approximately 30 additional patients will be entered at one or more dose levels at or below the MTD in order to determine the optimal dose for subsequent studies.

• Adequate renal function: serum creatinine < 1.5 x the upper limit of normal (ULN);
• Adequate hepatic function AST or ALT < 2.5 x the ULN; Total bilirubin < 1.5 x the ULN

Exclusion Criteria:

• Pregnant or lactating women.
• Women of childbearing potential and fertile men who are not practicing or who are unwilling to practice birth control while enrolled in the study until at least 12 weeks after the last hLL1 infusion;
• Prior chemotherapy, immunotherapy, radiotherapy, plasmapheresis, kyphoplasty, or major surgery within 4 weeks; prior stem cell transplant within 12 weeks; prior treatment with rituximab within 6 months. Must have recovered from all toxicity from prior treatments;
• Prior therapy with other murine, chimeric, human or humanized monoclonal antibodies, unless HAHA tested and negative;
• Prior treatment with any investigational agents within 3 months, unless completed follow-up, off study, and agreed by Sponsor;
• Prior malignancy within 5 years, excluding multiple myeloma, non-melanoma skins cancers and cervical carcinoma in situ;
• Known to be HIV positive, or hepatitis B or C positive;
• Known autoimmune disease or presence of autoimmune phenomena;
• Systemic infection or requiring anti-infectives within 7 days before first dose of study drug;
• Substance abuse or other concurrent medical conditions that, in the investigator's opinion, could confound study interpretation or affect the patient's ability to tolerate or complete the study.
