New Cancer Targets

• Cancer Cell Resistance to treatment – Platinum sensitive versus Platinum Resistance

• Cellular immunity pathways• Checkpoint Inhibitors

• Stromal Interaction with cancer Stromal Interaction with cancer

• Enhance Anti-Cancer Immune Systems

• Vaccines –– FANG individualized vaccine against the original ovarian

cancer cells.

• Monoclonal Antibodies

• Testing drugs that have been approved for other types of cancer (melanoma, breast)

Ovarian Cancer:Why the Anti-Angiogenesis ?

• Tumor angiogenesis is associated with malignantbehavior in ovarian cancer 1,2

• BEV as single-agent showed promising activity inrecurrent ovarian cancer in phase II studies3,4

• BEV combined with chemotherapy showed• BEV combined with chemotherapy showedpositive results in phase III randomized clinicaltrials in both platinum sensitive (OCEANS)5 aswell as platinum resistant ovarian cancer(AURELIA)6

Bevacizumab, in combination with carboplatin and paclitaxel is indicated for the front-line treatment of advanced (FIGO stages III B, III C and IV) epithelial ovarian, fallopian tube, or primary peritoneal cancer

Bevacizumab is administered in addition to carboplatin Bevacizumab is administered in addition to carboplatin and paclitaxel for up to 6 cycles of treatment followed by continued use of Bevacizumab as single agent until disease progression or for a maximum of 15 months or until unacceptable toxicity, whichever occurs earlier

The recommended dose of Bevacizumab is 15 mg/kg of body weight given once every 3 weeks as an intravenous infusion

Cediranib

• Angiogenesis Inhibitor

– a potent inhibitor of vascular endothelial growth factor receptor tyrosine kinases

• Oral• Oral

• Similar Side Effects of Olaparib

– Fatigue, Nausea, diarrhea, hypertension

Ursula A. Matulonis et al. JCO 2009;27:5601-5606

Combination of Olaparib and Cediranib

Based on Phase II Study

• Combined treatment vs monotherapy

– Tumors shrank more dramatically

– Greater delayed progression (compared to standard chemotherapy)chemotherapy)

– More complete remission with combination • (5 women in combination group and 2 women in monotherapy group)
