Impact of targeted therapyin ovarian cancer

Georges Chahine, M.D.Professor of Hematology – OncologySaint-Joseph University, Beirut

IntroductionOvarian cancer is the leading cause of death from GU cancer is the US

In 2015, 21290 newly diagnosed cases and 14180 deathfrom ovarian carcinoma were reported in USA

70% of patients present with advanced disease and lessthan 40% of them are cured

Nearly 70% of advanced stage cancer relapse

For many years, ovarian cancer has been managed using …

Management of previously treatedovarian cancer

Tumour resection and subsequent chemotherapy should be considered for all women with previously treated, platinum-sensitive ovarian cancer

– complete reresection significantly improves overall survival

The improvement in survival in patients with advanced stage ovarian cancer has been obtained by better management of recurrent disease and increased drug options, but we seem to have reached a plateau with chemotherapy

Harter, et al. Ann Surg Oncol 2006

Other strategies are needed…..Antiangiogenesis in ovarian cancer

Angiogenesis (VEGF) in ovarian cancer

Preclinical data• VEGF inhibitors inhibit tumour growth, abrogate ascites formation and normalise

vessels

Human data• VEGF overexpressed and associated with worse outcome• Associated with ascites and carcinomatosis• VEGF inhibition is synergistic with chemotherapy

Burger, et al. NEJM 2011

GOG-0218: conclusions

GOG-0218 met its primary objective of increasing PFS in front-line treatment of advanced ovarian cancer

PFS with CP + bevacizumab continued single-agent bevacizumab at 15mg/kg for 15 months (Arm III) was statistically superior to CP + placebo placebo (Arm I) in all analyses (13.1 vs 18.2 months)

Side effects were generally manageable, with a safety profile similar to that in bevacizumab studies in other tumour types

OCEANS: conclusions

Bevacizumab + carboplatin + gemcitabine followed by bevacizumab until progression provides a clinically meaningful benefit over chemotherapy alone in recurrent OC– improved PFS: HR 0.484 (p<0.0001);

median 8.4 → 12.4 months– improved ORR and duration of response– OS data not yet mature

Safety data consistent with bevacizumab profile– no GI perforations and no new safety signals

This regimen should be considered a new option for recurrent platinum-sensitive OC

Further optimisation of bevacizumab use Ongoing trials have been designed to address the

following in relation to bevacizumab– duration (AGO-OVAR 17)– combination with weekly paclitaxel (GOG-0262, OCTAVIA,

GOG-0252)– combination with intraperitoneal therapy (GOG-0252)– neoadjuvant setting (GOG-0262, ANTHALYA and NOVA)– use following progression after front-line bevacizumab

(MITO-16/MaNGO OV-2)

Conclusions

Conventional approaches to treating ovarian cancer have provided significant improvements in outcomes

The ability of such approaches to continue to improve outcomes has reached a plateau

Further progress appears likely based on the optimisation of bevacizumab use, other anti-angiogenic agents and other targeted therapies
