Brief Summary:
This study was a randomized, single dose crossover comparison of the investigational product with a Reference Product (vinorelbine tartrate injection, NAVELBINE®). The primary objective was to demonstrate the equivalence of ANX-530 and the Reference Product, NAVELBINE.

Condition or disease Intervention/treatment Phase
Breast Cancer Non-small Cell Lung Cancer Non-Hodgkins Lymphoma Drug: Vinorelbine Tartrate Phase 1

Detailed Description:
ANX-530 (vinorelbine tartrate injectable emulsion), an investigational drug, is an oil-in-water emulsion of vinorelbine tartrate composed of an oil phase and emulsifier dispersed in an aqueous solution. ADVENTRX Pharmaceuticals, Inc. of San Diego, California, developed ANX-530 as a vinorelbine tartrate formulation to be used in clinical settings where Vinorelbine Tartrate Injection (NAVELBINE) is indicated. Nonclinical toxicology studies suggest either equivalent or less toxicity of ANX-530 compared to Reference Product. In particular, ANX-530 caused less vein toxicity in a rabbit vein irritation model, suggesting ANX-530 could potentially cause less venous irritation than NAVELBINE in a clinical setting. ADVENTRX is investigating whether ANX-530 could substitute for NAVELBINE in these settings.

Actual Enrollment : 31 participants
Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Bioequivalence Study of Vinorelbine Tartrate Injectable Emulsion (ANX-530) in Patients With Advanced Cancer.
Study Start Date : February 2007
Actual Primary Completion Date : November 2007
Actual Study Completion Date : December 2007

Intervention Details:
  • Drug: Vinorelbine Tartrate
    Subjects received one dose each of ANX-530 and NAVELBINE, each providing 30 mg/m2 vinorelbine. Study drugs will be infused into an arm vein over ten minutes.
    Other Names:
    • Exelbine (proposed)
    • ANX-530

Primary Outcome Measures :
  1. Time to Reach Maximum Observed Plasma Concentration (Tmax) [ Time Frame: 0-144 hours post dose ]
  2. Maximum Observed Plasma Concentration (Cmax) [ Time Frame: 0-144 hours post-dose ]
  3. Area Under the Plasma Concentratio-Time Curve From Time 0 to the Time of the Last Measurable Concentration (AUClast) [ Time Frame: 0-144 hours post-dose ]
    Determined Using the Linear Trapezoidal Rule

  4. Area Under the Concentration-Time Curve From Time 0 to Infinity (AUCinf) [ Time Frame: 0-144 hours post-dose ]
    AUCinf = AUClast + (Clast/lamda z)

  5. Percentage of AUCinf Based on Extrapolation (AUCextrap) [ Time Frame: 0-144 hours post-dose ]
  6. Observed Elimination Rate Constant Associated With the Terminal Portion of the Curve (λ z) [ Time Frame: 0-144 hours post-dose ]
    Estimated via linear regression of the time versus log concentration

  7. Observed Terminal Elimination Half-Life (t1/2) [ Time Frame: 0-144 hours post-dose ]
    t1/2 = [ln(2)/λ z]

  8. Time of Last Measurable Concentration (Tlast) [ Time Frame: 0-144 hours post-dose ]
  9. Last Quantifiable Drug Concentration (Clast) [ Time Frame: 0-144 hours post-dose ]
  10. Mean Residence Time (MRTinf) [ Time Frame: 0-144 hours post-dose ]
    MRT = (AUMCinf)/(AUCinf)
