Temozolomide Phase II Clinical Study in Patients With Newly Diagnosed Glioblastoma Multiforme (Study P04661)(COMPLETED) - Full Text View

Sponsor:	Schering-Plough
Information provided by:	Schering-Plough
ClinicalTrials.gov Identifier:	NCT00684567

Purpose

The purpose of this study is to evaluate the safety of combination therapy of radiotherapy and temozolomide ("concomitant radiotherapy phase"), and then temozolomide monotherapy ("monotherapy phase"), in patients with newly diagnosed glioblastoma multiforme. Progression free survival and response rate will also be calculated.

Primary Outcome Measures:

Adverse Events With an Incidence of Greater Than or Equal to 20% [ Time Frame: until 30 days after the completion of administration of monotherapy ] [ Designated as safety issue: Yes ]
Adverse Drug Reactions With an Incidence of Greater Than or Equal to 20% [ Time Frame: until 30 days after the completion of administration of monotherapy ] [ Designated as safety issue: Yes ]
Abnormal Changes in Laboratory Test Values With an Incidence of Greater Than or Equal to 20% [ Time Frame: until 30 days after the completion of administration of monotherapy ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:

Number of Participants With Progression Free Survival (PFS) for 1 Year [ Time Frame: 1 year after the start of admininstration in the concomitant radiotherapy phase ] [ Designated as safety issue: No ]
Number of Participants With a Response (Complete Response [CR] + Partial Response [PR]) in Terms of Overall Tumor Response [ Time Frame: 1 year after the start of administration in the concomitant radiotherapy phase ] [ Designated as safety issue: No ]

Enrollment:	30

Arms	Assigned Interventions
Experimental: Single arm It is the only arm of the study. Subjects receive a combination of radiotherapy and temozolomide, and then temozolomide monotherapy.	Radiation: Radiotherapy Radiotherapy will be administered in combination with temozolomide during the concomitant radiotherapy phase. Radiotherapy will consist of a conventionally fractioned regimen, delivering a total dose of 60 Gy in 6 weeks, in a once daily schedule of 2 Gy per fraction, for a total of 30 fractions. Radiation will be provided by a linear accelerator of x ray energy of 4 MV or higher. Other Name: Irradiation, radiation therapy Drug: Temozolomide During the concomitant radiotherapy phase (6 weeks), temozolomide will be administered in combination with radiotherapy, once daily at 75 mg/m2/day. Then, during the monotherapy phase, subjects will receive 6 cycles of temozolomide alone. Each cycle will last 28 days, and temozolomide will be administered once daily from Day 1 to Day 5 of each cycle. The dose of temozolomide in the first cycle will be 150 mg/m2/day, and may be increased to 200 mg/m2/day for Cycle 2 and subsequent cycles depending on nonhematologic toxicity observed and neutrophil and platelet count values. Capsules containing 5 mg, 20 mg, or 100 mg of temozolomide will be combined to achieve each subject's calculated dose. Other Name: Temodal, Temodar, SCH 052365

Arms

Assigned Interventions

Experimental: Single arm

It is the only arm of the study. Subjects receive a combination of radiotherapy and temozolomide, and then temozolomide monotherapy.

Radiation: Radiotherapy

Radiotherapy will be administered in combination with temozolomide during the concomitant radiotherapy phase. Radiotherapy will consist of a conventionally fractioned regimen, delivering a total dose of 60 Gy in 6 weeks, in a once daily schedule of 2 Gy per fraction, for a total of 30 fractions. Radiation will be provided by a linear accelerator of x ray energy of 4 MV or higher.

Other Name: Irradiation, radiation therapy

Drug: Temozolomide

During the concomitant radiotherapy phase (6 weeks), temozolomide will be administered in combination with radiotherapy, once daily at 75 mg/m2/day. Then, during the monotherapy phase, subjects will receive 6 cycles of temozolomide alone. Each cycle will last 28 days, and temozolomide will be administered once daily from Day 1 to Day 5 of each cycle. The dose of temozolomide in the first cycle will be 150 mg/m2/day, and may be increased to 200 mg/m2/day for Cycle 2 and subsequent cycles depending on nonhematologic toxicity observed and neutrophil and platelet count values. Capsules containing 5 mg, 20 mg, or 100 mg of temozolomide will be combined to achieve each subject's calculated dose.
