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

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

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
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

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


                                                    Boyer et al. Ophthalmology 2009;116(9):1731-9

  • 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 Brown et al.

  • 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 Boyer et al.

  4. 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&lt;0.0001) or 9.4 and 6.7 letters for 6 mg/mL (p&lt;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
