Is GIST the Exception or the Rule?

• Drug with spectacular benefit

• Enrichment design

• Pent-up demand

• Prior therapy irrelevant

• Performance status irrelevant

GET SMART

SMART: Sarcoma Maintenance Assessed Randomized Trial

A randomized, prospective, double-blind, placebo-controlled

Phase III trial

Oral Tablet AP23573 Clinical Trial – Objectives

• Primary– Determine safety, tolerability and MTD of multiple dose schedules of

oral AP23573 studied in parallel

• Secondary

– Compare blood levels to those in the intravenous program showing anti-tumor activity

– Confirm mTOR inhibition by PD assays

– Describe anti-tumor activity

– Characterize PK parameters

Oral AP23573 Trial Status• 7 dose schedules studied in parallel

– MTD identified• Over 125 patients treated• Majority of patients with a diagnosis of sarcoma• Evidence of mTOR inhibition using pharmacodynamic assay• Many patients with prolonged stable disease

– On study 4-15+ months• Side effect profile consistent with i.v.

– Mouth sores main DLT• Final dose schedule being optimized for highest cumulative

dose and frequency of dosing together with tolerability to allow long-term use
