Trial Outcomes & Findings for Irinotecan and Temozolomide in Treating Patients With Breast Cancer Who Have Received Previous Treatment for Brain Metastases (NCT NCT00617539)
NCT ID: NCT00617539
Last Updated: 2018-04-20
Results Overview
Imaging was performed at 8-week intervals to assess response to treatment. Patients with known or suspected leptomeningeal disease were deemed to have a complete response if CSF cytology converted to negative (if positive at baseline) and all meningeal enhancement or nodularity of brain and/or spine MRI resolved. A modified RECIST 1.0 criteria was used to assess CNS response for patients with new or progressing brain metastases. In this modified RECIST criteria, CNS lesions \<1cm were not considered measurable, but were considered evaluable for response and progression. Progressive disease for patients with lesions \<1 cm was defined as follows: growth of a lesion from less than or equal to 5 mm to greater than or equal to 10mm; or, growth of a 6-9 mm lesion by at least 5 mm in the case of non-target parenchymal brain metastases.

PRIMARY outcome

Irinotecan and Temozolomide
n=30 Participants
irinotecan hydrochloride administered intravenously (IV) at a starting dose of 125 mg/m2 on days 1 and 15 of a 28 day cycle
temozolomide orally for seven days at a starting dose of 100 mg/m2 on days 1-7 and days 15-21 of a 28 day cycle

Number of Patients With Objective Treatment Response (Complete or Partial) in the CNS
|
2 Participants
|
PRIMARY outcome
Timeframe: From 1 day 1 (first day of treatment) every 8 weeks until scan shows disease progression or up to 2 yearsThe number of patients experiencing a clinical benefit is the sum of patients with an objective response plus patients with stable disease at ≥ 16 weeks from cycle 1 day 1 (first day of treatment). If a patient did not come back for a follow up scan after clinical deterioration, then they were only considered stable up to the time of the last scan they had per protocol.

SECONDARY outcome
Timeframe: Baseline scan prior to study entry was performed within 14 days of cycle 1 day 1, then every 8 weeks from then until disease progression or up to 2 yearsImaging at 8-week intervals to assess response to treatment. A modified RECIST 1.0 criteria was used to assess response and time to progression in the CNS for patients with progressing brain metastases. In this modified RECIST criteria, CNS lesions \<1cm were not considered measurable, but were considered evaluable for response and progression. Progressive disease for patients with lesions \<1 cm was defined as follows: growth of a lesion from less than or equal to 5 mm to greater than or equal to 10mm; or, growth of a 6-9 mm lesion by at least 5 mm in the case of non-target parenchymal brain metastases. If patient did not come back for a follow up scan after clinical deterioration, patient was only considered stable up to the time of the last scan per protocol and time to progression would be from cycle 1 day 1 to the last scan they completed that was stable.
