Trial Outcomes & Findings for Vorinostat and Bortezomib in Treating Patients With Progressive, Recurrent Glioblastoma Multiforme (NCT NCT00641706)

NCT ID: NCT00641706

Last Updated: 2014-05-14

Results Overview

Estimated using the Binomial point estimator (number of successes divided by the total number of evaluable patients). A patient is classified as a success if alive and progression-free at 6 months. For patients with bidimensionally measurable disease (measurable disease), progression is defined as \> 25% increase in product of perpendicular diameters of contrast enhancement or mass or appearance of new lesions. For patients without bidimensionally measurable disease (evaluable disease), progression is defined as unequivocal increase in size of contrast enhancement or increase in mass effect as agreed upon independently by primary physician and quality control physicians or appearance of new lesions.

Participant milestones
Measure
Arm A (Not Undergoing Surgery)
Patients receive oral vorinostat (SAHA) once daily on days 1-14 and bortezomib IV on days 1, 4, 8, and 11. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity. bortezomib : Given IV vorinostat : Given orally
Arm B (Undergoing Surgery)
Patients receive oral SAHA once daily for 2 days prior to surgery and then on the day of surgery. Patients also receive bortezomib IV on the day of surgery. After receiving the 3rd dose of SAHA, patients undergo surgery to remove the tumor. Beginning at least 7 days after surgery, patients receive SAHA and bortezomib as in stratum 1. surgery : Patient undergoes therapeutic conventional surgery bortezomib : Given IV vorinostat : Given orally

PRIMARY outcome

Timeframe: At 6 months

Population: Patients that started treatment.

Estimated using the Binomial point estimator (number of successes divided by the total number of evaluable patients). A patient is classified as a success if alive and progression-free at 6 months. For patients with bidimensionally measurable disease (measurable disease), progression is defined as \> 25% increase in product of perpendicular diameters of contrast enhancement or mass or appearance of new lesions. For patients without bidimensionally measurable disease (evaluable disease), progression is defined as unequivocal increase in size of contrast enhancement or increase in mass effect as agreed upon independently by primary physician and quality control physicians or appearance of new lesions.

SECONDARY outcome

Timeframe: From study registration to date of progression (up to 5 years)

Population: Patients that started treatment.

Estimated using Kaplan-Meier survival curve. Patients who died were considered to have disease progression at the time of death unless there was documented evidence that no progression occurred before death. For patients with bidimensionally measurable disease (measurable disease), progression is defined as \> 25% increase in product of perpendicular diameters of contrast enhancement or mass or appearance of new lesions. For patients without bidimensionally measurable disease (evaluable disease), progression is defined as unequivocal increase in size of contrast enhancement or increase in mass effect as agreed upon independently by primary physician and quality control physicians or appearance of new lesions.

Interval 0.6 to 9.3

SECONDARY outcome

Timeframe: Assessed up to 5 years

Population: Arm A patients that started treatment. Arm B patients were not analyzed for this outcome because they received surgery and hence response was not measured.

Confidence intervals for the true proportion will be calculated using the exact binomial method. Measurable patients must achieve at least a 50% reduction in the product of perpendicular diameters of contrast enhancement or mass with no new lesions with the patient being on stable or decreased steroid dose. Evaluable patients must achieve unequivocal reduction in size of contrast-enhancement or decrease in mass effect as agreed upon independently by primary physician and quality control physicians; no new lesions. Patient should be on stable or decreased steroid dose.
