Overview
Brief Summary
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.

Outcomes
Primary Outcomes
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
Safety was assessed from the start of administration during the concomitant radiotherapy phase until 30 days after the completion of administration of monotherapy.
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
Safety was assessed from the start of administration during the concomitant radiotherapy phase until 30 days after the completion of administration of monotherapy.
Adverse Events With an Incidence of Greater Than or Equal to 20%
Time Frame: until 30 days after the completion of administration of monotherapy
Safety was assessed from the start of administration during the concomitant radiotherapy phase until 30 days after the completion of administration of monotherapy. Adverse events were classified under the system organ class using MedDRA-J Version 11.0.
Secondary Outcomes
- Number of Participants With Progression Free Survival (PFS) for 1 Year(1 year after the start of admininstration in the concomitant radiotherapy phase)
- Number of Participants With a Response (Complete Response [CR] + Partial Response [PR]) in Terms of Overall Tumor Response(1 year after the start of administration in the concomitant radiotherapy phase)
