Drug: CYT997
Phase 2

Study Type: Interventional

Masking: Open Label
Primary Purpose: Treatment
Official Title: A Prospective, Single-arm, Two-stage, Open-label Phase II Trial of CYT997 in Relapsed and Refractory Multiple Myeloma

Further study details as provided by Gilead Sciences:

Primary Outcome Measures:
  • Overall response rate to CYT997 when used to treat patients with relapsed or refractory multiple myeloma [ Time Frame: Baseline to study completion ]
    The overall response rate to CYT997 when used to treat patients with relapsed or refractory multiple myeloma once every 3 week cycle

Secondary Outcome Measures:
  • Number of cycles required to achieve maximum response [ Time Frame: Baseline to study completion ]
  • Overall survival [ Time Frame: Baseline to study completion ]
  • Safety and tolerability [ Time Frame: Baseline to study completion ]
  • Time to disease progression [ Time Frame: Baseline to study completion ]

Study Start Date: January 2008
Study Completion Date: February 2011
Primary Completion Date: February 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: I
Drug: CYT997
Intravenous infusion (24h); 202mg/m2 on days 1 and 8 of a 21 day cycle


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

  • Have failed to respond to the most recently administered anti-myeloma therapy
  • Have a life expectancy of at least 3 months
  • Eastern Cooperative Oncology Group (ECOG) performance status < 3
  • At registration absolute neutrophil count > 1x10^9/L and platelet count > 50 x 10^9/L unsupported
  • At registration bilirubin less than 1.5 x upper limit of normal and transaminases less than 2 x upper limit of normal and serum creatinine less than 0.19 mmol/L
  • Written informed consent
  • Must agree to adequate contraceptive measure if indicated

Exclusion Criteria:

  • Patients with monoclonal gammopathy of undetermined significance
  • Known or suspected hypersensitivity to CYT997
  • Patient with uncontrolled intercurrent illness
  • Active infections or other illnesses that precludes chemotherapy administration or patient compliance.
  • Pregnant or lactating women.
  • Patients who have received any other investigational agents in the last 3 weeks prior to the start of treatment.
  • Patients with the following conditions will be excluded:

    • myocardial infarction or stroke within 6 months
    • unstable angina pectoris or acute ischemic changes on ECG
    • history of diabetic retinopathy
    • symptomatic peripheral arterial disease
    • major surgery in the last 30 days
  • Patients with uncontrolled diarrhea despite optimal medication and those with any history of acute gastrointestinal bleeding
  • Patients with a baseline prolongation of the QTc interval of Common Terminology Criteria (CTC) Grade 1 (QTc > 0.45-0.47 sec) or greater
  • Patients with impaired cardiac function or clinically significant cardiac diseases, including any one of the following:

    • left ventricular ejection fraction (LVEF) < 45% as determined by multigated acquisition (MUGA) scan or echocardiogram;
    • complete left bundle branch block;
    • obligate use of a cardiac pacemaker;
    • congenital long QT syndrome;
    • history or presence of ventricular tachyarrhythmia;
    • presence of unstable atrial fibrillation (ventricular response > 100 bpm). -Patients with stable atrial fibrillation are eligible, provided they do not meet any of the other cardiac exclusion criteria;
    • clinically significant resting bradycardia (< 50 bpm);
    • right bundle branch block + left anterior hemiblock (bifascicular block);
    • angina pectoris ≤ 3 months prior to starting study drug;
    • acute myocardial infarction (MI) ≤ 3 months prior to starting study drug; or
    • other clinically significant heart disease (e.g., congestive heart failure (CHF), uncontrolled hypertension, history of labile hypertension, or history of poor compliance with an antihypertensive regimen).
  • Patients currently receiving treatment with medications known to prolong the QTc interval and/or to induce Torsades de Pointes arrhythmia.
