Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Median Overall Survival Time | From randomization to last follow-up. Maximum follow-up at time of analysis was 4.4 years. | Overall survival time is defined as time from registration/randomization to the date of death from any cause. Overall survival rates are estimated by the Kaplan-Meier method. Patients last known to be alive are censored at the date of last contact. Analysis occurred after 647 deaths were reported. |
| Secondary | Median Progression-free Survival (PFS) Time | From randomization to last follow-up. Maximum follow-up at time of analysis was 4.4 years. | Progression is defined as greater than 25% increase in tumor area (two diameters) provided that the patient has not had his/her dose of steroids decreased since the last evaluation period. Progression-free survival time is defined as time from registration to the date of first progression, death, or last known follow-up (censored). Progression-free survival rates are estimated using the Kaplan-Meier method. A concomitant decrease in steroid dose will rule out a progression designation during the first 2 months after completion of radiation therapy. Analysis occurred after 647 deaths were reported. |
| Secondary | Median Overall Survival Time by MGMT Status | From randomization to last follow-up. Maximum follow-up at time of analysis was 4.4 years. | Overall survival time is defined as time from randomization to the date of death from any cause. Overall survival rates are estimated by the Kaplan-Meier method. Patients last known to be alive are censored at the date of last contact. Tumor tissue submitted at baseline was analyzed to determine MGMT (O\[6\]-methylguanine-DNA methyltransferase) promoter methylation status (methylated / unmethylated). Analysis occurred after 647 deaths were reported. |
| Secondary | Median Progression-free Survival Time by MGMT Status | From randomization to last follow-up. Maximum follow-up at time of analysis was 4.4 years. | Progression is defined as greater than 25% increase in tumor area (two diameters) provided that the patient has not had his/her dose of steroids decreased since the last evaluation period. Progression-free survival time is defined as time from registration to the date of first progression, death, or last known follow-up (censored). Progression-free survival rates are estimated using the Kaplan-Meier method. A concomitant decrease in steroid dose will rule out a progression designation during the first 2 months after completion of radiation therapy. Tumor tissue submitted at baseline was analyzed to determine MGMT (O\[6\]-methylguanine-DNA methyltransferase) promoter methylation status (methylated / unmethylated). Analysis occurred after 647 deaths were reported. |
| Secondary | Best Treatment Response by MGMT Status | From randomization to last follow-up. Maximum follow-up at time of analysis was 4.4 years. | Response assessed using Response Evaluation Criteria in Solid Tumors (RECIST v1.0): Complete Response (CR), imaging no longer shows enhancing tumor, confirmed by a second scan ≥ 4 weeks later; Partial Response (PR), \>=50% decrease in tumor area (two diameters) with patient off all steroids, or on adrenal maintenance only; Minor Response (MR), \< 50% decrease in tumor area with patient off all steroids, or on adrenal maintenance only; Stable Disease (SD): scan shows no change with patient receiving stable/decreasing doses of steroids; Progression (P): \> 25% increase in tumor area with no decrease in steroid dose since last evaluation. Tumor tissue submitted at baseline was analyzed to determine MGMT (O\[6\]-methylguanine-DNA methyltransferase) promoter methylation status (methylated / unmethylated). Analysis occurred after 647 deaths were reported. |
| Secondary | Distribution of Highest Grade AE Reported as Possibly/Probably/Definitely Related to Protocol Treatment | From randomization to last follow-up. Maximum follow-up at time of analysis was 4.4 years. | Highest grade adverse event (AE) per subject was counted. Adverse events were graded using the Common Terminology Criteria for Adverse Events (CTCAE) v3.0. Grade refers to the severity of the AE. The CTCAE v3.0 assigns Grades 1 through 5 with unique clinical descriptions of severity for each AE based on this general guideline: Grade 1 Mild, Grade 2 Moderate, Grade 3 Severe, Grade 4 Life-threatening or disabling, Grade 5 Death related to AE. Analysis occurred after 647 deaths were reported. |
| Secondary | Overall Survival Status by Progression Status at 6 Months | From randomization to last follow-up. Maximum follow-up at time of analysis was 4.4 years. | Overall survival time is defined as time from registration to the date of death from any cause or last known follow-up (censored). Overall survival rates are estimated by the Kaplan-Meier method. Progression is defined as greater than 25% increase in tumor area (two diameters) provided that the patient has not had his/her dose of steroids decreased since the last evaluation period. |
| Secondary | Mean MD Anderson Symptom Inventory Brain Tumor (MDASI-BT) Symptom Severity Score at Cycle 10 for Participants Without Progression After 6 Months of Adjuvant Therapy | Baseline and cycle 10 (approximately 46 weeks) | The MDASI-BT is a 28-item patient-reported outcome measure assessing symptom severity and resulting interference with daily living in brain cancer patients. All items range from 0 (not present) to 10 (as bad as you can imagine). The symptom severity score is the average of the symptom severity items, given a specified minimum numbers were completed. |
| Secondary | Mean Neurocognitive Function (NCF) Composite Score at Cycle 10 for Participants Without Progression After 6 Months of Adjuvant Therapy | Baseline and cycle 10 (approximately 46 weeks) | The NCF Composite score is the arithmetic mean of the Hopkins Verbal Learning Test - Revised (HVLT-R) (Free Recall, Delayed Recall, Delayed Recognition), Trail Making Test Part A (TMTA), Trail Making Test Part B (TMTB), and Controlled Oral Word Association (COWA) test scores, all of which are standardized, adjusting for age, education, and gender as necessary, such that mean is 0 and standard deviation is 1. A participant must have at least 5 of the 6 scores. A higher composite score indicates better neurocognitive function. |
| Secondary | Mean EORTC QLQ-C30 Global Health Status Score at Cycle 10 for Participants Without Progression After 6 Months of Adjuvant Therapy | Baseline and cycle 10 (approximately 46 weeks) | Global Health Status is calculated from two questions on the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire \[EORTC QLQ\]-C30. The question responses range from 1 "very poor" to 7 "excellent" such that a higher response indicates better quality of life (QOL). The mean of these responses is linearly transformed to a range of 0 (worst) to 100 (best). |
