Median OS: 16.6 months (BEV + CT) vs 13.3 months (CT)

Interpretation of OS is complicated by bevacizumab crossover (40%) and the lack of information on post-progression therapy

Exploratory subgroup analyses suggested:

Generally consistent effects on OS

More pronounced OS treatment effect in the weekly paclitaxel subgroup

Conclusions

After blockade of the VEGF pathway, there is a compensatory upregulation of FGF and PDGF

Trebananib (AMG 386) – Peptibody That Binds and Neutralizes Ang1 and Ang2

• Trebananib is an investigational recombinant peptide-Fc fusion protein (peptibody)

• In clinical studies trebananib has shown:

• Single-agent activity in relapsed ovarian cancer in a phase 1 study1

• Prolongation of PFS in a randomized phase 2 study in combination with paclitaxel in recurrent ovarian cancer2

Bottom Line… Anti-angiogenesis agents in ovarian cancer

– PFS appears to be enhanced by biological targeting

– The menu of available agents is expanding

– Toxicity and impact of therapy is needed to adjudicate use

Intervention is extending post treatment life expectancy

Better and selected therapy is needed for OS

recurrence Overall Survival (ITT) (2013 April Update)

Neither FAR dose met the study’s primary PFS endpoint in the ITT population

Most commonly reported adverse events across arms were those known to be associated with the study chemotherapy agents

Higher dose and exposure of FAR seems to be correlated with PFS improvement

Hypotheses: CA125 may inhibit the potential ADCC effect of FAR Hence, FAR in adequate dosing may have a potential effect in lower

CA125 populations

Novel Drug Development: Ovarian Many new agents being explored based on molecular

profiling Challenges:

– How can we improve OS?» Post-progression survivorship is long and increasing» Are there better measures of treatment effect?

– What is the best strategy to meet individualization of care?– How do we identify, prevent, avoid, and overcome drug-

resistance?– How can therapy be optimized while reducing off/on-target

toxicity?
