BAFF Antibody

Tabalumab, LY2127399

BAFF Antibody Derived from Dal Porto; Kurosaki; Mackay and Schneider.1-3

Target

B-cell activating factor (BAFF) is a member of the TNF family and has been shown to be an important survival factor for peripheral B cells. BAFF has been implicated in conferring a survival advantage to B-cell malignancies, such as multiple myeloma.4

Molecule

Tabalumab (LY2127399) is a fully human monoclonal antibody that was designed to have neutralizing activity against both membrane-bound and soluble BAFF.5

Clinical Development

Tabalumab is being investigated in clinical trials for the treatment of multiple myeloma.

BAFF Antibody

A Multicenter, Randomized, Double-Blind, Placebo-Controlled Phase 2 Study of Tabalumab in Combination With Bortezomib and Dexamethasone in Patients With Previously Treated Multiple Myeloma

Key Inclusion Criteria

  • Have symptomatic and/or progressive multiple myeloma that was previously treated with at least 1 and no more than 3 prior lines of therapy
  • Prior therapy with bortezomib is allowed if it resulted in at least a minimal response and there was no relapse or progression of multiple myeloma within 60 days of the last dose of bortezomib
  • Treatment with prior autologous transplant is permitted. If a transplant is used as consolidation following chemotherapy, without intervening disease progression, it will be considered 1 line of treatment with the preceding chemotherapy

Key Exclusion Criteria

  • Have had less than a minimal response or have had progressive disease within 60 days of most recent therapy with a proteasome inhibitor
  • Plan to proceed to autologous transplant for consolidation after treatment on Study JDCG
  • Have positive test results for human immunodeficiency virus (HIV), evidence of hepatitis B (positive for hepatitis B surface antigen, or positive for hepatitis B core antibody and negative for hepatitis B surface antibody) or positive test results of hepatits C virus (HCV; positive for anti-hepatitis C antibody)
