Ipilimumab  Overview  •  Therapeu5c  Class  

–  Recombinant,  human  monoclonal  anBbody  that  binds  to  cytotoxic  T-­‐lymphocyte-­‐associated  anBgen  4  (CTLA-­‐4)  

•  Indica5on  –  Treatment  of  unresectable  or  metastaBc  melanoma  

•  Mechanism  of  Ac5on  –  Blocks  interacBon  of  CTLA-­‐4  with  ligands,  thereby  upregulaBng  immune  acBvity    

•  Dosing/Administra5on  –  3  mg/kg,  administered  intravenously  over  90  minutes  every  3  weeks  for  a  total  of  4  doses  

Page 5: Milovac P&T Competition Presentation

Disease  Background  •  Melanoma  

–  One  of  the  10  most  prevalent  cancers  in  the  United  States  –  Commonly  found  on  the  head,  neck,  legs,  shoulders,  hips  

•  Risk  Factors  –  Environmental    –  GeneBc    

•  Diagnosis  –  Physical  examinaBon    –  Skin  biopsy    – MRI,  PET,  CT  scan    

Page 6: Milovac P&T Competition Presentation

Burden  of  Disease  •  Prevalence  

–  In  2011,  the  prevalence  of  melanoma  in  the  United  States  was  esBmated  to  be  960,231    

–  Incidence  in  2014  is  esBmated  to  exceed  76,000  –  Per  100,000  individuals,  the  approximated  annual  number  of  new  cases  was  27,  with  nearly  15  of  these  individuals  expected  to  be  75  or  older  

•  Humanis5c  and  Economic  Burden  –  PaBents  with  metastaBc  melanoma  have  a  median  survival  Bme  of  9  months  and  3-­‐year  survival  rates  below  15%  

–  Average  healthcare  costs  in  the  year  following  diagnosis  esBmated  to  be  $48,921

Real  World  ComparaBve  EffecBveness  •  Evidence  from  RCT’s  for  increased  survival  is  convincing  

–  LimitaBons  •  Large  sample  sizes  difficult  to  construct  •  Inclusion/exclusion  criteria  somewhat  inconsistent  •  Prior  therapies  differ  vastly  in  those  previously  treated  

•  Few  studies  directly  compare  ipilimumab  to  other  agents  as  monotherapy  –  Available  data  trend  toward  superior  efficacy  with  more  extensive  adverse  event  profile  for  ipilimumab  

•  Ongoing  trials:  high-­‐dose  interferon  alfa-­‐2b  monotherapy  in  high-­‐risk  paBents;  sargramosBm  combinaBon  therapy
