Performance with sql query

Hi Experts,

Can you please help in reducing the runtime for the below query. This sql is never ending.

Attached all the statistics required.

SELECT invs.invoice_id,wi.item_key,           
wi.root_activity, wi.root_activity_version,           
wi.owner_role, wi.parent_item_type,           
wi.parent_item_key,wi.parent_context,           
wi.begin_date, wi.end_date,           wi.user_key,           
wi.ha_migration_flag, wi.security_group_id    FROM ( SELECT /*+ qb_name(iview) */ 3371328 invoice_id FROM dual ) 
invs, wf_items wi,  wf_item_attribute_values wiav    
WHERE wi.item_type = 'APINVAPR'    AND   wi.end_date is null    AND   
wi.item_type = wiav.item_type    AND   wi.item_key = wiav.item_key    
AND   wiav.name = 'INVOICE_ID'    AND   wiav.number_value = 
invs.invoice_id    AND  NOT EXISTS (SELECT 1 FROM wf_item_attribute_values  wiav2  WHERE wiav2.item_type = 
'APINVAPR'             AND   wiav2.item_key  = wi.item_key
