Cervical Cancer: Avastin Efficacy Data

Persistent, recurrent, or metastatic cervical cancer (CC)
Avastin, in combination with paclitaxel and cisplatin or paclitaxel and topotecan, is indicated for the treatment of patients with persistent, recurrent, or metastatic cervical cancer.

Avastin plus chemotherapy demonstrated statistically significant overall survival (OS) vs chemotherapy alone in CC in the GOG-0240 study[1]

GOG-0240 study: OS results in CC patients

  • 3.9-month increase in median OS: 16.8 months with Avastin plus chemotherapy vs 12.9 months with chemotherapy alone[1]
    • Hazard ratio (HR)=0.74 (95% confidence interval [CI], 0.58–0.94); P=0.0132

Chemotherapy included either cisplatin/paclitaxel or topotecan/paclitaxel.
GOG=Gynecologic Oncology Group.

Select Important Safety Information

The Warnings and Precautions for Avastin include gastrointestinal perforation and fistulae, surgery and wound healing complications, hemorrhage, arterial thromboembolic events, venous thromboembolic events, hypertension, posterior reversible encephalopathy syndrome, renal injury and proteinuria, infusion-related reactions, embryo-fetal toxicity, ovarian failure, and congestive heart failure.

GOG-0240 study: Efficacy data overview[1]

Endpoint   Avastin + chemotherapy Chemotherapy alone HR (95% CI) P value
  Number of patients 227 225    
Primary OS (median) 16.8 months 12.9 months 0.74 (0.58–0.94) 0.0132
Secondary ORR 45% (95% CI, 39%–52%) 34% (95% CI, 28%–40%)    

Chemotherapy included either cisplatin/paclitaxel or topotecan/paclitaxel.
ORR=overall response rate.

Avastin plus chemotherapy demonstrated increases in OS and ORR[1]

  • A 30% increase in median OS vs chemotherapy alone (16.8 vs 12.9 months)
  • A 26% reduction in the risk of death vs chemotherapy alone

OS results by chemotherapy regimen (platinum doublet vs nonplatinum doublet) were also evaluated in the GOG-0240 study, regardless of combination with Avastin[1]

Chemotherapy analysis of the GOG-0240 study: platinum doublet vs nonplatinum doublet

  Topotecan/paclitaxel ± Avastin
Cisplatin/paclitaxel ± Avastin
Median OS (months) 13.3 15.5
HR 1.15 (95% CI, 0.91–1.46)
  • HR for OS with Avastin plus cisplatin/paclitaxel vs cisplatin/paclitaxel alone was 0.72 (95% CI, 0.51–1.02)
  • HR for OS with Avastin plus topotecan/paclitaxel vs topotecan/paclitaxel alone was 0.76 (95% CI, 0.55–1.06)

The GOG-0240 study evaluated Avastin plus chemotherapy vs chemotherapy alone for CC[1,16]

  • The GOG-0240 study was a randomized, active-controlled, multicenter study conducted in the US and Spain through GOG and the Spanish Research Group for Ovarian Cancer, and was sponsored by the National Cancer Institute
  • The primary endpoint of the GOG-0240 study was OS, and the secondary endpoint was ORR

The GOG-0240 study included a diverse population of women with CC[1]
