Avastin/Temozolomide/Irinotecan for Unresectable/Multifocal Glioblastoma Multiforme

Phase 2

Completed

Conditions: Glioblastoma Multiforme
Gliosarcoma

Interventions: Drug: Avastin
Drug: Temozolomide
Drug: Irinotecan

Registration Number: NCT00979017

Lead Sponsor: Katy Peters

Brief Summary: The primary objective of the study is to determine the efficacy of Avastin in combination with temozolomide and irinotecan in terms of response rate. The secondary objectives are to describe the overall and progression-free survivals of unresectable patients treated with upfront Avastin, temozolomide and irinotecan and to assess the safety of Avastin, temozolomide and irinotecan in unresectable glioblastoma patients.

This is a phase II study with the combination of Avastin, temozolomide and irinotecan for unresectable or multifocal World Health Organization (WHO) grade IV malignant glioma patients. Patients will receive up to four cycles of Avastin, temozolomide and irinotecan. Approximately 41 subjects will take part in this study at Duke.

History of abdominal fistula, gastrointestinal perforation, or intra-abdominal abscess within 6 months prior to study enrollment
Serious, non-healing wound, ulcer, or bone fracture
Proteinuria at screening as demonstrated by either urine protein:creatinine (UPC) ratio > or = to 1.0 at screening OR urine dipstick for proteinuria ≥ 2+ (patients discovered to have ≥2+ proteinuria on dipstick urinalysis at baseline should undergo a 24-hour urine collection and must demonstrate ≤ 1g of protein in 24 hours to be eligible).
Known hypersensitivity to any component of Avastin
Pregnant (positive pregnancy test) or lactating. Use of effective means of contraception (men and women) in subjects of child-bearing potential

Arm && Interventions

Group	Intervention	Description
Avastin in combination with temozolomide and irinotecan	Avastin	Avastin 10 mg/kg every 14 days. Temozolomide 200 mg/m2 daily x 5 days in a 28-day cycle. Irinotecan dose depends on whether the patient is on an enzyme-inducing antiepileptic drug (EIAED). EIAED 340 mg/m2 every other week and no EIAED 125 mg/m2 every other week. Irinotecan dose also depends on if the patient has the UGT 1A1 polymorphism (7/7). If so, they do not metabolize the irinotecan normally, so these patients will start out at a two dose level reduction. EIAED starting dose will be 275 mg/m2 and no EIAED starting dose will be 75 mg/ m2.

Primary Outcome Measures

Name	Time	Method
Response Rate	4 months	The percentage of participants with a complete or partial response as determined by a modification of the Response Assessment in Neuro-Oncology (RANO) criteria. Complete Response (CR) was defined as complete disappearance on MR/CT of all enhancing tumor and mass effect, off all corticosteroids (or receiving only adrenal replacement doses) and accompanied by a stable or improving neurologic examination. Partial Response (PR) was defined as greater than or equal to 50% reduction in tumor size on MR/CT by bi-dimensional measurement, on a stable or decreasing dose of corticosteroids and accompanied by a stable or improving neurologic examination. Per the criteria, confirmation of response was required. Response rate = CR+PR.

Secondary Outcome Measures

Name	Time	Method
Incidence and Severity of Central Nervous System (CNS) Hemorrhage and Systemic Hemorrhage	4 months	Incidence and severity of CNS hemorrhage and systemic hemorrhage- The adverse events for this study were collected using Common Terminology Criteria for Adverse Events (CTCAE) version 3.0, and have been converted to CTCAE version 4.0 for entry into ClinicalTrials.gov.
Incidence of Grade ≥ 4 Hematologic and ≥ Grade 3 Non-hematologic Toxicities	4 months	Incidence of treatment-related, grade ≥ 4 hematologic and ≥ grade 3 non-hematologic toxicities- The adverse events for this study were collected using Common Terminology Criteria for Adverse Events (CTCAE) version 3.0, and have been converted to CTCAE version 4.0 for entry into ClinicalTrials.gov.
Median Progression-free Survival (PFS)	36 months	Time in months from the start of study treatment to the date of first progression according to RANO criteria, or to death due to any cause. Per RANO, progression is a ≥ 25% increase in the sum of the products of perpendicular diameters of enhancing lesions, worsening T2/FLAIR, any new lesion, or clinical deterioration. Patients alive who had not progressed as of the last follow-up had PFS censored at the last follow-up date. Median PFS was estimated using a Kaplan-Meier curve.
Median Overall Survival (OS)	36 months	Time in months from the start of study treatment to the date of death due to any cause. Patients alive as of the last follow-up had OS censored at the last follow-up date. Median OS was estimated using a Kaplan-Meier curve.
