Safety [ Time Frame: Safety is measured during the treatment period and for a minimum of 12 weeks after the treatment period for a maximum of 2 years. ]
Safety evaluations include monitoring for infusion reactions or other acute adverse events, cardiac assessments (EKG, troponin T, BNP, MUGA scan or 2D-ECHO), vital signs, physical examination, routine safety laboratories (hematology, serum chemistries, urinalysis), serum immunoglobulins, and B- and T-cell levels, with immunogenicity analyzed by the Sponsor from human anti-milatuzumab antibody serum titers (HAHA). Antibody pharmacokinetics will be evaluated by hLL1-DOX serum levels analyzed by the Sponsor.

A Study of hLL1-DOX (Milatuzumab-Doxorubicin Antibody-Drug Conjugate) in Patients With Multiple Myeloma
A Phase I/II Study of hLL1-DOX (Milatuzumab-Doxorubicin Antibody-Drug Conjugate) in Patients With Multiple Myeloma
This study is a Ph I trial to test the safety of the study drug, hLL1-DOX at different dose levels in patients with recurrent multiple myeloma. HLL1 is also known as milatuzumab and is attached to doxorubicin in this clinical trial.
In this clinical research trial, hLL1-DOX will be administered on days 1, 4, 8 and 11. This treatment cycle will be repeated every 3 weeks as long as patients continue to tolerate it, for a maximum of 8 treatment cycles (approximately 6 months).
Phase 1
Phase 2
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Multiple Myeloma
Drug: hLL1-DOX (the doxorubicin conjugate of milatuzumab)
hLL1-DOX will be administered intravenously (through a vein) on days 1, 4, 8 & 11 every 21 days for up to 8 treatment cycles. 4 different dose levels of hLL1-DOX will be studied for safety and tolerability.
Other Names:
  • hLL1-DOX
  • Milatuzumab-DOX
  • CD74-DOX
Experimental: hLL1-DOX
4 Different dose levels of hLL1-DOX will be studied in groups of 3-6 patients. Once an optimal dose has been found, up to additional 30 patients will be studied at that dose level.
Intervention: Drug: hLL1-DOX (the doxorubicin conjugate of milatuzumab)
