Different gold standard diagnostics
with common ancillary tests
Neovascular AMD DME
Early detection of neovascular AMD is DME is diagnosed stereoscopically as
possible with an retinal thickening in the macula using
Amsler grid1 fundus contact lens biomicroscopy3
FA is essential to confirm diagnosis of
neovascular AMD, and to identify the
location and composition of the CNV1
Ancillary tests:3
Ancillary tests:2
FA – identification and evaluation of
ICGA – delineation of choroidal vessel fluid leakage from lesions
morphology
OCT – measurement of retinal thickness
OCT – measurement of retinal thickness

19. Conclusions MARINA study
• The results from MARINA demonstrate that intravitreal
Ranibizumab is associated with clinically and statistically
significant benefits with respect to VA in patients with minimally
classic or occult lesions with no classic CNV associated with
neovascular AMD over a
2-year period
• In patients treated with Ranibizumab, efficacy was maintained
throughout the 2-year period whereas patients in the sham
group continued to experience a decline in vision
Rosenfeld et al. N Engl J Med 2006; 355: 1419-1431
20. Conclusions (2)
• Ranibizumab was well tolerated over a 2-year period
• Efficacy outcomes were achieved with a low rate of serious ocular
AEs and no clear difference from the sham-treated group in the
rate of non-ocular AEs
• Subsequent to the results of the ANCHOR and MARINA trials,
Ranibizumab was licensed for the treatment of neovascular AMD
by the US Food and Drug Administration in 2006 and in the
European Union in 2007

27. Conclusions ANCHOR study
• Ranibizumab demonstrated efficacy in patients with
subfoveal, predominantly classic CNV associated with
neovascular AMD over a 2-year period
– treatment with monthly intravitreal Ranibizumab prevented central
vision loss and improved mean VA
– VA benefit from Ranibizumab was both rapid (within one month) and
sustained (over the 2-year study period)
– Ranibizumab was superior to treatment with verteporfin PDT for
patients losing <15 letters from baseline and mean change in VA over
time
Brown et al. Ophthalmology 2009; 116: 57-65
28. Conclusions
• Improvements in VA from baseline seen (2-year) are greater in
ANCHOR than MARINA
– ANCHOR patients had predominantly classic CNV lesions; MARINA patients had
minimally classic or occult with no classic CNV lesions
– average CNV lesion size was smaller in ANCHOR; however, predominantly classic
lesions are typically more aggressive and lead to more rapid loss of VA than
minimally classic lesions, therefore the potential for improvement is greater
– predominantly classic lesions are typically diagnosed early and therefore treated
earlier than occult lesions which may account for the greater improved VA
outcomes observed
• recent VA loss associated with rapidly progressing predominantly classic CNV may be partially
reversible whereas earlier VA loss due to slowly progressing occult CNV may be irreversible, providing
little opportunity for VA improvement with treatment

37. Study objective and endpoints
• Primary objective: to evaluate the safety and
tolerability of intravitreal Ranibizumab in
neovascular AMD
• Primary endpoint: incidence of ocular and
non-ocular serious adverse events (SAEs)
• Key secondary endpoints
– incidence of ocular and non-ocular AEs
– change from baseline in visual acuity

41. Safety conclusions
• Similar rates of APTC events overall, or individually for myocardial
infarction and vascular deaths between doses
• A trend was seen toward higher stroke and non-vascular death in
the 0.5 mg arm; this was not statistically significant and the number
of events was small (cohort 1)
• Prior stroke was the most significant risk factor identified for stroke
in cohort 1, independent of treatment
– the number of patients with a history of stroke was small; however, in this
subgroup there was a non-significant trend toward higher stroke rate in the
0.5 mg group than in the 0.3 mg group
• Ocular safety was consistent between doses and with prior
Ranibizumab studies

P value from the two-sided stratified Cochran-Mantel-Haenszel testThe primary objective was met with statistically significant superiority of ranibizumab monotherapy vs. sham, with least square means treatment differences of 7.9 letters (pooled doses, p<0.0001) or 9.4 and 6.7 letters for 6 mg/mL (p<0.0001) and 10 mg/mL (p=0.0004) ranibizumab, respectively.The primary efficacy variable is the mean average BCVA change from Month 1 through Month 12 compared to baseline for each of the patients in the trial. For each single Patient (P), the average change in BCVA is calculated as follows (Δ BCVAMx = change in BCVA from baseline at Month x): average Δ BCVAP1= (Δ BCVAM1 + Δ BCVAM2 + Δ BCVAM3 + ...+ Δ BCVAM12)/12average Δ BCVAP2= (Δ BCVAM1 + Δ BCVAM2 + Δ BCVAM3 + ...+ Δ BCVAM12)/12average Δ BCVAP3= (Δ BCVAM1 + Δ BCVAM2 + Δ BCVAM3 + ...+ Δ BCVAM12)/12 :average Δ BCVAPn= (Δ BCVAM1 + Δ BCVAM2 + Δ BCVAM3... ...+ Δ BCVAM12)/12The mean average BCVA change from Month 1 through Month 12 compared to Baseline is calculated as follows:(average Δ BCVAP1 + average Δ BCVAP2 +.....+ average Δ BCVAPn)/n where n = the number of patients in the trial
