Brief summary

The primary objective of this trial is to compare the survival of patients with advanced non-small cell lung cancer (NSCLC) treated with weekly Taxoprexin in combination with carboplatin to those treated with paclitaxel plus carboplatin in a prospectively randomized trial. In addition, the response rate to each regimen, response duration, time to progression and time to treatment failure will be measured. Toxicity will be evaluated and compared between the two groups.

Detailed description

This is a randomized, multicenter, Phase III open-label study of weekly Taxoprexin® in combination with every three (3) week carboplatin compared to paclitaxel plus carboplatin every three (3) weeks, in patients with advanced non-small cell lung cancer (NSCLC) who have not received cytotoxic agents for advanced disease. Patients may have been previously treated with immunological agents. Patients will be randomized to receive Taxoprexin® at a dose of 400 mg/m2 intravenously by one (1)-hour weekly infusion, 5/6 weeks followed immediately by carboplatin AUC = 4 on weeks one (1) and four (4) as a 30 minute intravenous infusion or paclitaxel 225mg/m2 as a three (3) hour intravenous infusion followed immediately by carboplatin AUC = 6 as a 30 minute intravenous infusion, every three (3) weeks. Patients will receive Taxoprexin® and carboplatin infusions or paclitaxel and carboplatin infusions until progression of disease, intolerable toxicity, completion of six (6) treatment cycles of paclitaxel plus carboplatin or three (3) treatment cycles of Taxoprexin® plus carboplatin, refusal of continued treatment by the patient, or Investigator decision.

Interventions

Administered by intravenous infusion over 1 hour infusion

DRUGCarboplatin

Administered by intravenous infusion over 30 minutes. Dosing was based on the Calvert formula: carboplatin dose (mg) = (Target AUC) x (glomerular filtration rate (GFR) + 25).

DRUGPaclitaxel

Administered by intravenous infusion over 3 hour infusion

MeasureTime frameDescription
Overall SurvivalUp to 12 monthsOverall survival was defined as the time from the day of randomization and ends at death of the participant. Participants were followed every 2 months, whether on or off study, for survival information. Participants alive at the time of termination of the study were considered censored.

Secondary

MeasureTime frameDescription
Percentage of Participants Who Achieved an Objective Complete Response or Partial ResponseAssessed every 6 weeks, up to 12 monthsAntitumor response was defined as the percentage of participants who achieved an objective response (Complete Response or Partial Response), confirmed by repeat assessments performed no less than 4 weeks after the criteria for response were first met. Response was based on the blinded radiological review using Response Evaluation Criteria in Solid Tumors (RECIST) response guidelines, Version 1.0. A complete response was defined as a disappearance of all target lesions determined by 2 consecutive observations not less than 4 weeks apart. Partial response was defined as a 30% decrease in the sum of the longest diameters (LD) of target lesions, taking as reference the baseline sum of LD determined by 2 consecutive observations not less than 4 weeks apart.
Duration of ResponseAssessed every 6 weeks, up to 12 monthsDuration of overall response was a measurement from the time measure criteria was met for confirmed complete response or partial response (whichever was first recorded) until the first date that recurrent of progressive disease was objectively documented (taking as reference for progressive disease the smallest measurement recorded since treatment started).
Time to Progression (TTP)Up to 12 monthsTTP was defined as the time from randomization to documented disease progression. Progressive disease was defined as at least a 20% increase in the sum of longest diameter (LD) of target lesions, taking as references the smallest sum LD recorded since treatment start or the appearance of 1 or more lesions.
Time to Treatment Failure (TTF)Baseline to stopping treatment, up to 12 monthsTTF is defined as the time from randomization to the discontinuation of protocol treatment for any reason
