|LOGO |  | CLINICAL TRIAL
PROTOCOL CONCEPT  Proposed Phase II Study of
GDC-0084 in Glioblastoma Multiforme



|I. | STUDY OBJECTIVE
|-- | ---------------

This study is intended to demonstrate safety and efficacy of
GDC-0084 in the treatment of glioblastoma multiforme (GBM) in the adjuvant setting, following surgical resection and radiotherapy.

The study is designed to maximise the potential for accelerated approval of the product following completion.



|II. | STUDY POPULATION
|--- | ----------------

All subjects will have a histologically-confirmed diagnosis of GBM (WHO Grade IV), and an
unmethylated MGMT status, as confirmed by PCR or alternative genomic analysis. Prior to study entry, subjects will have had optimal surgical resection and subsequent treatment with radiotherapy and temozolomide, in accordance with the Stupp
regimen. Subjects who have had disease progression or recurrence subsequent to radiotherapy treatment will not be eligible.

Other
eligibility criteria will be as commonly deployed for oncology studies. Both male and female subjects will be recruited.



|III. | STUDY DESIGN
|---- | ------------

The study is a multicentre, two-arm, randomised,
double-blind clinical trial, using temozolomide as an active comparator.

Following completion of radiotherapy treatment according to the
Stupp regimen, subjects will be assigned to one of two treatment groups, in a 1:1 ratio. The first group will receive temozolomide, in accordance with the labelled dose and schedule. The second group will receive GDC-0084 at a dose of 45mg, once daily.

Sample Size

It is expected that approximately 160 subjects will be recruited to the study (80 subjects in each of two arms). Subjects may be stratified according to the
Karnofsky Performance Status (KPS) and age.
