Fight disease progression with GLIVEC 800 mg/day1-4

  • Dose escalation following progression is the recommended next step in advanced GIST1-3*
  • Dose escalation to GLIVEC 800 mg/day is recommended for patients experiencing progression on 400-mg therapy1-3*
  • Dose escalation prior to switching therapies retains future therapeutic options1,2
Progressive KIT+ GIST: recommended sequence of treatment options1,2
  • At initial progression, a switch from imatinib to sunitinib should be considered only if imatinib causes life-threatening side effects that cannot be managed by maximum supportive treatment1
  • Surgical resection of progressing lesions should be considered, if appropriate1,2

About 1 in 3 patients with metastatic KIT+ GIST benefited from dose escalation with GLIVEC5

Many patients with progression achieve disease control with GLIVEC 800 mg/day.5†

  • 31% of patients in a Phase 3 unresectable and/or metastatic study who dose-escalated to 800 mg/day after progression at 400 mg/day achieved stable disease or partial response6
    Median progression-free survival after crossover to 800 mg/day was 5 months (95% CI, 2-10 months)6
    Patients who tolerated the 400-mg dose prior to dose escalation were less likely to require dose reductions at the 800-mg level than patients initiated at the higher dose5

GLIVEC has demonstrated efficacy in advanced KIT+ GIST, regardless of mutational status7

  • Approximately 95% of GISTs are KIT+, and the vast majority have activating mutations in the KIT or PDGFRA genes8
    Relative frequencies of GISTs with KIT exon 11 and exon 9 mutations are 68% and 10%, respectively9
    95% of tumours with KIT exon 9 mutations are in the small bowel8
  • KIT exon 11 and 9 mutations are responsive to GLIVEC therapy7
    93% of assessable patients with KIT exon 11 mutations achieved disease control, with 72% showing objective response in a large Phase 3 study7†
    89% of assessable patients with KIT exon 9 mutations achieved disease control, with 44% showing objective response in the same study7†
  • In advanced KIT+ GIST, ESMO guidelines recommend GLIVEC 800 mg/day upon confirmation of exon 9 mutation2
    In a meta-analysis of two large Phase 3 dosing studies for GLIVEC, patients with KIT exon 9 mutations treated with GLIVEC 800 mg/day (n=49) had a 42% reduction (P=0.017) in the estimated risk of progression vs similar patients treated with 400 mg/day (n=42)10
