PR104 in Treating Patients With Previously Untreated or Relapsed Small Cell Lung Cancer

Phase 2
Terminated
Conditions
Lung Cancer
Interventions
Other: F-18-fluoromisonidazole
Registration Number
NCT00544674
Lead Sponsor
Proacta, Incorporated
Brief Summary

RATIONALE: Drugs used in chemotherapy, such as PR-104, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing.

PURPOSE: This phase II trial is studying how well PR-104 works in treating patients with previously untreated or relapsed small cell lung cancer (SCLC).

Detailed Description

OBJECTIVES:

Primary

* Estimate the response rate of PR-104 in patients with treatment-naive or sensitive-relapse small cell lung cancer.

* Evaluate safety of this drug in these patients. Secondary

* Evaluate survival of these patients.

* Evaluate progression-free survival of these patients.

* Evaluate time to progression in these patients.

* Assess the pharmacokinetics (PK) of PR-104 and its alcohol metabolite.

* Estimate the rate of hypoxia using 18F-fluoromisonidazole (FMISO) positron emission topography (PET) imaging.

* Collect plasma samples for assessment of potential biomarkers of tumor hypoxia.

OUTLINE: This is a multicenter study. Patients are stratified according to disease type (treatment-naive vs sensitive-relapse).

Patients receive PR-104 intravenously (IV) over 1 hour on day 1. Treatment repeats every 21 days for up to 4 courses (for treatment-naive patients) or in the absence of disease progression or unacceptable toxicity (for sensitive-relapse patients).

PK studies are performed during course 1 and after course 3. Blood is collected at baseline, during course 1, and at study completion for biomarker studies of tumor hypoxia (plasma proteins). Patients also undergo FMISO PET and fludeoxyglucose F18 (FDG) PET scans at baseline and after the second course of study therapy.

Primary Outcome Measures
NameTimeMethod
Response Rate (Complete or Partial)From registration until disease progression/recurrence
Safety and Tolerability: the Number of Subjects Experiencing a Serious Adverse Events30 days following the last administration of study treatment

The number of participants with at least one Serious Adverse Event was measured.

Secondary Outcome Measures
NameTimeMethod
SurvivalEvery 3 months for 2 years after discontinuation
Progression-free SurvivalTumor measurements and assessments based on Response Evaluation Criteria In Solid Tumors (RECIST) criteria were performed 6 weeks after first dose and as dictated by subject's malignancy

Progression free survival (PFS) is the time (days) from date of registration to date of first observed disease progression (radiological or clinical, whichever was earlier) or death due to any cause, if death occurred before progression was documented.

Time to ProgressionFrom registration of the first subject until radiological progression or recurrence whichever came first

Time to progression (TTP) was defined as the time from date of registration to radiological progression / recurrence. Subjects without progression at the time of analysis were censored at their last date of tumor evaluation.
