FOR  IMMEDIATE  RELEASE     Silence  Therapeutics  provides  corporate  and  development  update         London,   UK,  November  8,   2011  –Silence   Therapeutics   plc   (AIM:   SLN)   (“Silence”   or   the   “Company”),   a   leading   RNA   interference   (RNAi)   therapeutics   company,   today  provides   an   update  on  recent  business  and  clinical  developments.       Expansion  of  business  development  team   Silence   today   announces   the   appointment   of   Dr   Georg   Buchner   as   VP   Busines s   Development.  Georg   will  work   with   Tony   Sedgwick   who   was   appointed   as   Silence’s   Chief   Business  Officer  in  September  as  part  of  the  Company’s  strategy  to  continue  to  broaden  its   collaborations   with   global  pharmaceutical  and  biotechnology  companies.  Georg   was   formerly   VP   of   Corporate   &   Business   Development   at   Novacta   Biosystems   Ltd.   Prior   to   joining   Novacta,   Georg   was   Business   Development  Director  at   Haptogen   Ltd   and   was   instrumental  in  the  sale  of  the  business  to  Wyeth  (now  part  of  Pfizer)  in  2007.  Georg  gained   a  PhD  in  Molecular  Genetics  from  King’s  College  London  and  an  MBA  from  The  University  of   Cambridge’s  Judge  Institute  of  Management.     Atu027  trial  update   Results   from   the   ongoing   Phase   I   trial   of   Atu027,   Silence’s   lead   siRNA   development   programme for   the   treatment   of   advanced   solid   cancer,  now   confirm   that   10   out   of   27   (37%)  patients  treated  to  date  have  shown  stable  disease  after  the  treatment  phase  of  the   trial.  Dosing  of  the  first  patient  in  cohort  10  of  the  11  cohort  trial  has  now  commenced  and   the   trial   is   on   track   to   complete   recruitment   in   early   2012   with   results   reported   by   mid-­‐ 2012.     Atu027   incorporates  AtuPLEX™,   Silence’s   proprietary   delivery   technology   that   transports  RNAi  molecules  to  the  target  site  with  high  specificity.     Atu134  development  update   Following  further  encouraging  data  generated  from  the  ongoing  Phase  I  trial  of  Atu027  and   additional  data  from  preclinical  models  of  Atu134,  Silence  has  concluded  that  the  potential   clinical   profiles   of   Atu027   and   Atu134   are   too  similar   to   warrant   further   development   of   both  programmes.  The  Company  has  therefore  decided  to  divert  the  research  resources  for   Atu134   to   more   promising   areas   of   its   RNAi   delivery   technologies.  Consequently  Silence   is   evaluating  a   number   of   other  development   opportunities   for   potential   targets   in   the   liver   that  could  be  inhibited  by  using  Silence’s  novel  liver-­‐focused  DBTC  RNAi  delivery  system  in   order  to  identify  the  most  suitable  replacement  candidate  for  progression.     Thomas  Christély,  Chief  Executive  Officer  of  Silence  Therapeutics,  said:  “We  are  pleased  to   welcome  Dr   Georg   Buchner   to   Silence.     Georg   has   a   strong   track   record   in   business   development  and  his  experience  will  strengthen  our  growing  business  development  team  as   we  seek  to  expand  our  increasing  list  of  corporate  partnerships.  The  results  from  the  ongoing   Atu027  trial  continue   to   validate  Silence’s  development   capabilities   and   the   safety   of   our   innovative  AtuPLEX™   RNAi   delivery   system.  We   also   look   forward   to   exploring  the   full   capabilities   of   our   novel   DBTC  l i v e r   delivery   system   for   which   Silence   is   experiencing   increasing  interest  from  the  pharma  and  biotech  industry.”       -­‐-­‐Ends-­‐-­‐                 For  further  information,  please  contact:         Silence  Therapeutics   Thomas  Christély/Max  Herrmann   +49  30  9489

 (www.silence-­‐therapeutics.com)   Silence  Therapeutics  plc  (AIM:  SLN)  is  a  leading  biotechnology  company  dedicated  to  the  discovery,   development   and   delivery   of   targeted,   systemic   RNA   interference   (RNAi)   therapeutics   for   the   treatment  of  serious  diseases.  Silence  offers  one  of  the  most  comprehensive  short  interfering  RN A   (siRNA)  therapeutic  platforms  available  today  based  on  a  strong  intellectual  property  portfolio  and   large  clinical  safety  database.  Silence’s  clinical  siRNA  product  pipeline  is  one  of  the  broadest  in  the   industry.     The   Company   possesses   multiple   propriet ary   siRNA   delivery   technology   platforms   including   AtuPLEX™,   DACC   and   DBTC.   AtuPLEX   enables   the   broad   functional   delivery   of   siRNA   molecules   to   targeted  diseased  tissues  and  cells,  while  increasing  their  bioavailability  and  intracellular  uptake.  The   DACC   delivery   system   allows   functional   delivery   of   siRNA   molecules   selectively   to   the   lung   endo-­‐ thelium   with   a   long   duration   of   target   mRNA   and   protein   knock-­‐down.   The   DBTC   delivery   system   enables  functional  delivery  of  siRNA  molecules  selectively  to  liver  cells  including  hepatocytes.     Additionally,   the   Company   has   a   platform   of   novel   siRNA   molecules   based   around   its   AtuRNAi   chemical  modification  technology,  which  provides  a  number  of  advantages  over  conventional  siRNA   molecules.   Silence’s   unique   RNAi   assets   also  include   structural   features   for   RNAi   molecules   and   specific  design  rules  for  increased  potency  and  reduced  off-­‐target  effects  of  siRNA  sequences.       The   Company’s   lead   internal   drug   candidate   is   Atu027,   a   liposomal   formulation   in   clinical   development   for   systemic   cancer   indications   and   one   of   the   most   clinically   advanced   RNAi   therapeutic   candidates   in   the   area   of   oncology.   Atu027   incorporates   two   of   the   Company’s   technologies,   AtuRNAi   and   AtuPLEX™.   Silence   is   currently   conducting   an   open-­‐label,   single-­‐centre,   dose-­‐escalation  Phase  I  study  with  Atu027  in  patients  with  advanced  solid  tumors  involving  single,  as   well  as  repeated,  intravenous  administration.  Encouraging  interim  safety  and  pharmacokinetic  data   were  presented  at  the  American  Society  of  Clinical  Oncology  Annual  Meeting  in  June  2011.  The  study   is  expected  to  be  completed  in  the  first  half  of  2012.     The  Company’s  RNAi  therapeutic  platform  has  received  key  validation  through  multiple  partnerships   with   pharmaceutical   companies   including   AstraZeneca,   Dainippon   Sumitomo,   Pfizer/Quark,   and   Novartis/Quark.   Silence   is   actively   pursuing   the   establishment   of   additional   partnerships.   Silence   Therapeutics  has  operations  in  both  Berlin  and  London.     Forward-­‐Looking  Statements   This   press   release   includes
