This is an open-label, dose escalation study designed to characterize the safety, tolerability, efficacy, and pharmacokinetics of GNKG168 in patients with B-CLL that has relapsed or is refractory to all prior standard therapy, or for which no standard therapy exists.
As secondary objectives, baseline TLR-9 intracellular staining of B-CLL cells, and in vitro assays to assess the potential of B-CLL cells to undergo apoptosis in conjunction with GNKG168 therapy will be examined. Baseline characteristics of B-CLL will be examined including interphase genetics, FISH CLL, IgVH mutational status, expression of ZAP70, β2-microglobulin and the expression of the prognostic marker CD38 in peripheral blood cells (at baseline and during treatment) and baseline immune SNPs (FcγRIIIa, FcγRIIa, TNF-α, IFN-γ, CD40 and others). As pharmacodynamics parameters, the expression of B-cell and T-cell activation markers (including IL-21 receptor upregulation), NK cell markers, and cytokines will be investigated.
This clinical trial will also assess the ability of B CLL patients treated with GNKG168 to elicit anti pneumococcal antibodies in response to adjuvant vaccination with the Prevnar™ vaccine.
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||18 participants|
|Intervention Model:||Single Group Assignment|
|Masking:||None (Open Label)|
|Official Title:||A Phase I Study of GNKG168 Administered by Intravenous Infusion in Patients With Relapsed or Refractory B-Cell Chronic Lymphocytic Leukemia (B-CLL)|
|Study Start Date :||September 2009|
|Primary Completion Date :||November 2013|
|Study Completion Date :||November 2013|
The starting dose will be 0.25 mg/kg. If the dose is tolerable, subsequent cohorts will be enrolled and treated with 0.5, 0.75, 1.0 and 1.5 mg/kg. If 0.25 mg/kg proves to be intolerable, the dose will be reduced to 0.15 mg/kg.
GNKG168 will be administered as a 60 minute IV infusion once daily for 5 days followed by a 9 day rest period.
