Information provided by (Responsible Party):
This study was an early-phase trial arranged into two phases. The Phase I portion was a dose-escalation study designed to assess the safety, tolerability and to identify the maximum tolerated dose of SB-743921 in patients with Non-Hodgkin Lymphoma and Hodgkin Lymphoma. Phase II was intended to assess the activity, safety and tolerability of SB-743921 in patients with Indolent and Aggressive Non-Hodgkin's Lymphomas exclusively. The Phase II portion of the study was not initiated.

Condition Intervention Phase
Non-Hodgkin's Lymphoma Hodgkin's Disease Drug: SB-743921 Phase 1 Phase 2

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase I-II Study to Determine the Safety, Pharmacokinetics and Potential Efficacy of Intravenous Administration of SB-743921 on Days 1 and 15 of a 28-Day Dosing Schedule in Patients With Non-Hodgkin Lymphoma and Hodgkin Lymphoma

Further study details as provided by Cytokinetics:

Primary Outcome Measures:
  • Phase 1: Determination of Maximum Tolerated Dose (MTD) First Without and Then With Administration of Prophylactic G-CSF. [ Time Frame: 28 days ]
    Maximum Tolerated Dose (MTD) was determined by testing increasing doses in cohorts with at least 3 patients each. MTD reflects the highest dose of drug that did not cause dose limiting toxicity (DLT).

Secondary Outcome Measures:
  • Phase 1: Pharmacokinetics of SB-743921 Administered on a Days 1 and 15 of a 28 Day Cycle. [ Time Frame: 28 days ]

Enrollment: 68
Study Start Date: April 2006
Study Completion Date: July 2010
Primary Completion Date: July 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Phase 1 Dose Escalation
Phase 1 dose escalation without and with GCSF support
Drug: SB-743921
Phase 1: I.V. dose on Days 1 and 15 of a 28 day cycle starting at 2mg/m2 and increasing by 1 mg/m2 with possible prophylactic granulopoietic support until unacceptable toxicity develops.
Experimental: Phase 2 Fixed Dose
Phase 2 fixed dose based on Phase I findings stratified by NHL type
Drug: SB-743921
Phase 2: I.V. dose and regimen will be determined based on Phase 1 findings.

Inclusion Criteria: Phase 1: Patients with evaluable or measurable (by MRI or CT) Hodgkin's Disease or Non-Hodgkin's Lymphoma. Phase 2: Patients with Measurable Non-Hodgkin's Lymphomas (Indolent or Aggressive) only. - Patients with Indolent NHL must be relapsed or refractory to at least one prior line of therapy (CHOP, CVP, chlorambucil or fludaribine). Prior treatment with Rituximab is required. - Patients with Aggressive NHL refractory to (or relapsed from) at least one CHOP-based therapy who have had prior treatment with Rituximab and who are not candidates for high-dose chemotherapy or autologous stem cell transplantation. - ECOG performance status 0-2 - Autologous stem cell transplant recipients are eligible if 100 days have elapsed since procedure. Exclusion Criteria: Phase 1: History of prior radioimmunotherapy (Bexxar, Zevalin); These patients ARE permitted in the Phase 2 trial. - Current active malignancy besides NHL, except excised non-melanoma skin cancer, in-situ cervical or bladder cancer or early stage prostate cancer. - Patients with leptomeningeal of CNS lymphoma - Known allergy to and/or receipt of treatments contraindicated by administration of G-CSF - Patients with active Hepatitis B or C, or patients with HIV infection. - Pregnant or breast-feeding females. - Previous treatment with a KSP inhibitor
