Newly Diagnosed Advanced Ovarian Cancer
Ovarian Carcinoma: Incidence and Mortality
• Incidence in US women
– 21,880 cases in 2010
– Eighth most common cancer
– Second most common gynecologic cancer
– 1.5% lifetime risk of getting ovarian cancer
• Mortality in US women
– 14,850 deaths in 2010
– Fifth most common cause of cancer death
– Most common cause of death due to gynecologic
cancer
– 1.0% lifetime risk of dying of ovarian cancer

Annals Of Oncology 16 (Supplement 8) Viii7–viii12, 2005
Basis for Current Standard:
Systemic Therapy
• Studies showing paclitaxel/cisplatin superior to
cyclophosphamide/cisplatin
– GOG Protocol 111[1]
– EORTC-NCIC OV 10[2]
• Studies showing paclitaxel/carboplatin at least
equivalent to paclitaxel/cisplatin in efficacy
– AGO Trial[3]
– GOG Protocol 158[4]

Summary and Conclusions
• Advanced ovarian cancer is very lethal despite
many active medicines
• IV carboplatin and paclitaxel standard adjuvant
front-line therapy
• Little survival benefit in recurrent setting
• No approved targeted agent
• No agent approved since 2006

Olaparib:
Another PARP Inhibitor Abandoned in
Ovarian Cancer
Press Release - Dec 20, 2011
• The previously reported progression free survival benefit
is unlikely to translate into an overall survival benefit, the
definitive measure of patient benefit in ovarian cancer
• Attempts to identify a suitable tablet dose for use in
Phase III studies have not been successful.
