Trial Outcomes & Findings for Panitumumab and Irinotecan for Malignant Gliomas (NCT NCT01017653)

NCT ID: NCT01017653

Last Updated: 2013-09-04

Results Overview

Percentage of participants surviving six months from the start of study treatment without progression of disease. PFS was defined as the time from the date of study treatment initiation to the date of the first documented progression according to the Macdonald criteria, or to death due to any cause. Macdonald criteria are standard criteria in neuro-oncology. Tumor assessment was made according to the adapted MacDonald criteria based on the combined evaluation of: 1) assessment of the MRI scan for measurable, evaluable, and new lesions (made by the independent external expert too), 2) overall assessment of neurological performance (made by the investigator), and 3) concomitant steroid use (as reported by the investigator).

Measure
Panitumumab and Irinotecan
Panitumumab in Combination with Irinotecan : Panitumumab, 6mg/kg, as an intravenous infusion every other week in combination with Irinotecan (dose dependent upon whether the patient is taking an enzyme-inducing anti-epileptic drug \[EIAED\]). On an enzyme-inducing anti-epileptic drug (EIAED), irinotecan will be dosed at 340 mg/m2 every other week. Not on an EIAED, irinotecan will be dosed at 125 mg/m2. Treatment will continue until tumor progression or unacceptable toxicity.

SECONDARY outcome

Timeframe: 16 months

Population: 2 patients' response was unknown due to withdrawal from the study before an MRI was performed.

Number of participants with an objective response (complete response or partial response) based on modified Macdonald criteria. A complete response is defined as the disappearance of all enhancing rumor and mass effect, off all corticosteroids, accompanied by a stable or improving neurologic examination, and maintained for at least 4 weeks. A partial response is defined as greater than or equal to 50% reduction in tumor size on MR (magnetic resonance) / CT(computed tomography) by bi-dimensional measurement on a stable or decreasing dose of corticosteroids, accompanied by a stable or improving neurologic examination, and maintained for at least 4 weeks.
