linoleic	
   (LA)	
   and	
   gamma-­-linolenic	
   acid	
   (GLA)	
   are	
   reducing	
   eye	
   inflammation,	
   and	
  
n-­-6	
   pathway	
   eicosanoids	
   are	
   considered	
   as	
   promoting	
   inflammation	
   (32,	
   33).	
  
Omega-­-3	
   and	
   omega-­-6	
   EFAs	
   are	
   used	
   for	
   dry	
   eye	
   treatment	
   due	
   to	
   their	
   anti-­-
inflammatory	
   effects	
   such	
   as	
   the	
   drug	
   Nutrilarm®	
   of	
   the	
   French	
   company	
   Théa	
  
Laboratoires,	
   which	
   is	
   already	
   commercialized	
   in	
   Europe.	
   This	
   medicine	
   uses	
   a	
  
supplementation	
   of	
   omega-­-3	
   and	
   omega-­-6	
   fatty	
   acids,	
   which	
   according	
   to	
   the	
  
company	
   reduce	
   expression	
   of	
   the	
   conjunctival	
   inflammatory	
   marker	
   human	
  
leucocyte	
   antigen-­-DR	
   (HLA-­-DR)	
   and	
   may	
   help	
   improving	
   DED	
   symptoms.	
   The	
  
compound	
   past	
   in	
   2006	
   from	
   Phase	
   II	
   clinical	
   trials	
   in	
   US	
   (ClinicalTrials.gov	
  
Identifier:	
   NCT00357201)	
   but	
   the	
   company	
   decided	
   to	
   continue	
   the	
   pre-­-clinical	
  
development	
  to	
  resolve	
  efficacy	
  and	
  doses	
  issues	
  (34-­-36).	
  

ORAL	
  OMEGA-­-3-­-ACID	
  ETHYLESTERS	
  

        Pennsylvania	
   State	
   University	
   and	
   the	
   American	
   Society	
   of	
   Cataract	
   and	
  
Refractive	
   Surgery	
   Foundation	
   (ClinicalTrials.gov	
   Identifier:	
   NCT01107964)	
  
started	
   in	
   April	
   2010	
   a	
   clinical	
   study,	
   based	
   on	
   the	
   hypothesis	
   that	
   oral	
   omega-­-3-­-
acid	
   ethyl	
   esters	
   (Lovaza,	
   GlaxoSmithKline)	
   will	
   decrease	
   the	
   dry-­-eye	
   related	
  
symptoms	
   as	
   well	
   as	
   clinical	
   markers	
   associated	
   to	
   dry	
   eye	
   disease.	
   The	
  
preliminary	
  results	
  of	
  the	
  study	
  are	
  positive	
  but	
  more	
  research	
  is	
  needed	
  to	
  define	
  
the	
  composition	
  and	
  dosing	
  of	
  the	
  treatment.	
  From	
  the	
  results	
  it	
  was	
  confirmed	
  the	
  
relationship	
   between	
   EFA	
   supplementation	
   and	
   improvement	
   in	
   dry	
   eye	
  
symptoms	
   in	
   patients	
   (37).	
   Nevertheless	
   before	
   any	
   anti-­-inflammatory	
   therapy	
   is	
  
necessary	
  a	
  detailed	
  examination	
  of	
  a	
  patient	
  due	
  to	
  the	
  complexity	
  of	
  the	
  disease	
  
and	
  to	
  provide	
  individual	
  and	
  successful	
  treatment	
  (38).	
  	
  

SECUKINUMAB	
  AND	
  CANAKINUMAB	
  

        Novartis	
   Pharmaceuticals	
   Inc.	
   presented	
   two	
   novel	
   antibodies,	
  
Secukinumab	
   (AIN457)	
   and	
   Canakinumab	
   (ACZ885).	
   Secukinumab	
   is	
   a	
   fully	
  
human	
  monoclonal	
  antibody	
  designed	
  to	
  bind	
  selectively,	
  inhibiting	
  the	
  member	
  A	
  
of	
   interleukin	
   17cytokine	
   family,	
   a	
   key	
   driver	
   of	
   immune-­-mediated	
   diseases.	
  
Canakinumab	
   is	
   a	
   fully	
   human	
   monoclonal	
   antibody,	
   inhibiting	
   solely	
   interleukin	
  
1ß	
   (IL-­-1ß),	
   the	
   form	
   of	
   the	
   interleukin-­-1	
   protein	
   that	
   is	
   the	
   main	
   cause	
   of	
   various	
  
inflammatory	
   diseases	
   (39).	
   Currently	
   both	
   antibodies	
   are	
   under	
   development	
   as	
  
treatments	
   of	
   a	
   wide	
   range	
   of	
   auto	
   inflammatory	
   diseases.	
   In	
   November	
   2010	
  
Novartis	
  started	
  a	
  Phase	
  II	
  study	
  on	
  effects	
  of	
  a	
  single	
  intravenous	
  administration	
  
of	
   Secukinumab	
   10	
   mg/kg	
   or	
   Canakinumab	
   10	
   mg/kg	
   on	
   72	
   dry	
   eye	
   patients
