         or a pharmaceutically acceptable salt thereof. 
       
     
     
         28 . A pharmaceutically acceptable salt of the antisense oligomer conjugate of  claim 27 . 
     
     
         29 . The antisense oligomer conjugate of  claim 27 , wherein the antisense oligomer is of Formula (IIIA): 
       
         
           
           
               
               
           
         
         
           
           
               
               
           
         
         
           
           
               
               
           
         
         
           
           
               
               
           
         
       
     
     
         30 . The antisense oligomer conjugate of  claim 27 , wherein the antisense oligomer is of Formula (IV): 
       
         
           
           
               
               
           
         
         
           
           
               
               
           
         
         
           
           
               
               
           
         
         
           
           
               
               
           
         
         or a pharmaceutically acceptable salt thereof. 
       
     
     
         31 . A pharmaceutically acceptable salt of the antisense oligomer conjugate of  claim 30 . 
     
     
         32 . The antisense oligomer conjugate of  claim 30 , wherein the antisense oligomer is of Formula (IVA):
