(Nasdaq: KBIO) today announced preliminary results of an ongoing multi-center Phase 1 study of KB004, an anti-EphA3 monoclonal antibody (mAb), which the company is developing as a treatment for hematologic malignancies. Forty-four patients with refractory disease or who were unfit for chemotherapy have been enrolled in the dose escalation portion of the study. The experimental patient-targeted therapeutic has been well tolerated, with initial evidence of clinical activity.
Preliminary results of the study were presented yesterday by lead investigator, Jeffrey E. Lancet, M.D. of the H. Lee Moffitt Cancer Center & Research Institute, Tampa, Florida at the 55th American Society of Hematology Annual Meeting and Exhibition (ASH), held this week in New Orleans, Louisiana.
"We are encouraged by the results seen with KB004 to date, which has been well-tolerated at doses up to 190 mg, with mild to moderate transient infusion reactions the most common toxicity," said Dr. Lancet. "There are some signs of activity as well, including a patient with relapsed acute myeloid leukemia (AML) who had sustained remission for over 1 year."
Escalating doses of KB004 were administered as a 1 or 2 hour infusion on days 1, 8, and 15 of a 21 day cycle at incremental doses of 20, 40, 70, 100, 140, 190 and 250 mg and will thereafter increase at 33% increments up to a planned maximum of 700 mg. The primary study objective is to determine a maximum tolerated dose, which has not yet been reached. Secondary objectives included evaluation of pharmacokinetics, imm
