  • 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 ]
    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.
  • 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 ]
    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 ] [ Designated as safety issue: Yes ]
    Safety was assessed from the start of administration during the concomitant radiotherapy phase until 30 days after the completion of administration of monotherapy.
  • Safety from the start of administration during the monotherapy phase until 30 days after the completion of administration of monotherapy. [ Time Frame: From the start of administration during the monotherapy phase until 30 days after the completion of administration of monotherapy. ] [ Designated as safety issue: Yes ]
  • Safety from the start of administration during the monotherapy phase until the end of six cycles of monotherapy. [ Time Frame: From the start of administration during the monotherapy phase until the end of six cycles of monotherapy. ] [ Designated as safety issue: Yes ]
  • Safety from the start of administration during the concomitant radiotherapy phase until 30 days after the completion of administration of monotherapy. [ Time Frame: From the start of administration during the concomitant radiotherapy phase until 30 days after the completion of administration of monotherapy. ] [ Designated as safety issue: Yes ]
  • Safety from the start of administration during the concomitant radiotherapy phase until 4 weeks after the completion of radiotherapy. [ Time Frame: From the start of administration during the concomitant radiotherapy phase until 4 weeks after the completion of radiotherapy. ] [ Designated as safety issue: Yes ]
  • Safety from the start of administration during the concomitant radiotherapy phase until the end of six cycles of monotherapy.

  • 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 ]
    Administration of SCH 52365 was continued until progression was observed (progression was judged by the investigator based on MRI and clinical symptoms).
  • 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 ]

    CR = measurable lesion disappeared.

    PR = total sum of lesions measurable in bidimension decreased by 50% or more on whole and no secondary progression attributable to tumor was noted. No onset of new lesion.

Temozolomide Phase II Clinical Study in Patients With Newly Diagnosed Glioblastoma Multiforme (Study P04661)(COMPLETED)
SCH 52365 Phase II Clinical Study in Patients With Newly Diagnosed Glioblastoma Multiforme

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 Purpose: Treatment
Glioblastoma
  • 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
Experimental: Single arm
It is the only arm of the study. Subjects receive a combination of radiotherapy and temozolomide, and then temozolomide monotherapy.
