1 Miles DW et al. SABCS 2009;Abstract 41.
Final Overall Survival (OS) Results from the Randomised, Double-Blind, Placebo-Controlled, Phase III AVADO Study of Bevacizumab (BV) Plus Docetaxel (D) Compared with Placebo (PL) Plus D for the First-Line Treatment of Locally Recurrent (LR) or Metastatic Breast Cancer (mBC) Miles DW et al. SABCS 2009;Abstract 41. Unless it is a matter of spacing, the title should always match what the authors have written exactly. The 2nd line in the citation should not be italicized. Only if journal portion of reference line should be italicized.

2 Introduction Three Phase III trials (AVADO1, ECOG-21002, and RIBBON-13) have reported positive results with bevacizumab (BV) in the first-line mBC setting (1ASCO 2008;LBA1011, 2NEJM 2007;357:2666, 3ASCO 2009;1005). AVADO demonstrated significantly improved progression-free survival (PFS) with BV plus docetaxel (D) at 10 months follow-up. Median PFS: 8.7 mos (7.5 mg/kg BV + D), 8.8 mos (15 mg/kg BV + D), and 8.0 mos (D + placebo). Final overall survival (OS) and updated results of other study endpoints at 25 months follow-up are presented in the current analysis from the AVADO study. Not sure 1st bullet is needed. I would think most people are familiar with what bevacizumab is? Format for internal citations-(Journal abbrev. Year;vol:first page) 2nd bullet-is there any specific numbers that we can quote and list as sub-bullets? 3rd bullet-what are the numbers for PFS? This can be included as a sub-bullet of this point. Study objectives-include that final results are from AVADO trial Source: Miles DW et al. SABCS 2009;Abstract 41.

3 R AVADO Study Design Accrual: 736 (closed) Eligibility
Docetaxel 100 mg/m2 + Placebo q3w x 9 * Eligibility 1st-line locally recurrent or mBC HER2-negative No prior chemotherapy for locally recurrent or mBC, unless relapse is >6 months since last dose (>12 months if taxane-based) Docetaxel 100 mg/m2 + bevacizumab 7.5 mg/kg q3w x 9 * R I think it should be q3w x 9 instead of q3w[arrow]* You can still denote with asterisk that bev or placebo administered until PD Where did you get information under eligibility? I don’t see info for no prior therapy unless relapse > 6 mos since last dose. Docetaxel 100 mg/m2 + bevacizumab 15 mg/kg q3w x 9 * *Bevacizumab or placebo administered until disease progression Sources: Miles DW et al. SABCS 2009;Abstract 41; Miles DW et al.

Patients with measurable disease at baseline BV, 7.5 mg/kg + docetaxel (n = 201) BV, 15 mg/kg + docetaxel (n = 206) Placebo + docetaxel (n = 207) Overall response rate (ORR) p-value (vs control)† 55.2% 0.0739 64.1% 0.0003 46.4% Intent to treat population (n = 248) (n = 247) (n = 241) 1-year survival rate 81% 0.198 84% 0.02 76% Patients still at risk (n) 195 201 178 Changed the structure of the table. You can compare with your original version. More consistent with our style of tables for 5MJC. † p values are of exploratory nature. Source: Miles DW et al. SABCS 2009;Abstract 41.

8 Select Adverse Events > Grade 3
Bev, 7.5 mg/kg + docetaxel (n = 252) Bev, 15 mg/kg + docetaxel (n = 247) Placebo + docetaxel (n = 231) Febrile neutropenia (%) 15.1 16.6 11.7 Hypertension (%) 0.8 4.5 1.3 Bleeding (%) 1.2 0.9 Wound-healing complications (%) 0.4 Venous thromboembolic events (%) 1.6 3.5 GI perforation (%) Remove (%) from title and place % next to each numerical value listed in table. I think GI perforations are a serious AE assoc. w/ bev-can fit in those values in last row that I inserted. Source: Miles DW et al. SABCS 2009;Abstract 41.

9 Conclusions First-line BV (15 mg/kg) plus docetaxel significantly improves PFS and overall response rate compared to docetaxel alone in patients with HER2- mBC. PFS: 10.0 mos vs 8.1 mos ORR: 64.1% vs 46.4% Addition of increasing doses of BV to docetaxel therapy has a limited impact on the existing docetaxel safety profile. No difference in OS was observed between the study arms. Exploratory analysis in patients receiving post-progression treatment suggests that the use of 2nd-line BV with chemotherapy may influence OS (data not shown).

11 A 75-year-old with node+ trip neg BC presents with symptomatic metastases after completion of AC  T 2 years ago. What would you likely recommend if patient is not eligible for a clinical trial? (Check all that apply) Capecitabine/bevacizumab 31% Capecitabine 26% Platinum (alone or doublet)/ bevacizumab 12% Platinum (alone or doublet) 7% Ixabepilone/bevacizumab 5% Ixabepilone 4% Other 15% 0% 10% 20% 30% 40% If the patient were eligible for a Phase III trial randomizing to gem/carbo alone or with a PARP inhibitor (BSI-201) 86% would recommend enrollment.
