Cytokinetics' CY 2121 Study is an early-phase trial arranged into two phases. The objectives of the first phase of the study are to assess the safety, tolerability and to identify the maximum tolerated dose of the drug SB-743921 in patients with Hodgkin's Disease and Non-Hodgkin's Lymphomas. The second phase of the study is designed to assess the activity, safety and tolerability of SB-743921 in patients with Indolent and Aggressive Non-Hodgkin's Lymphomas exclusively.

Further study details as provided by Cytokinetics:

Primary Outcome Measures:
  • Phase 1: Determination of Dose-Limiting Toxicity (DLT) and Maximum Tolerated Dose (MTD) first without and then with administration of prophylactic G-CSF. [ Time Frame: 28 days ] [ Designated as safety issue: Yes ]
  • Phase 2: Frequency of Disease Response according to IWRC Criteria (Cheson,1999) [ Time Frame: 28 days ] [ Designated as safety issue: No ]

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 ] [ Designated as safety issue: No ]
  • Phase 2: Overall survival, progression-free survival. Time to and duration of response in patients who respond (CR, CRu, PR) to treatment. Frequency of disease response by (18-FDG PET), effects of SB-743921 on biomarkers [ Time Frame: >=28 days ] [ Designated as safety issue: No ]

Estimated Enrollment: 100
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: 1
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: 2
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.


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
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
