IC 265 is being developed for the treatment of dry eye

Dry eye disease (DED) is a chronic inflammatory condition affecting 334 million people worldwide.

IC 265 is being developed with the ability to significantly improve both the safety and efficacy of existing DED therapies.

In a Phase 2 conjunctival allergy challenge study, IC 265 demonstrated the following:

Fast to act

Takes 1 to 4 hours to reduce physiological responses

Well tolerated

Had no adverse effects reported relating to discomfort

Reduced redness

Was effective in reducing redness when dosed 8 hours prior to administration of allergy challenge

Reduced inflammation

Was effective in reducing inflammation demonstrated by confocal microscopy

IACTA’s R&D in action

IC 265 uses our SYK kinase inhibitor that is able to block multiple downstream signaling pathways leading to different ophthalmic ailments, including dry eye.

IC 265: Development strategy

Scientific and clinical validation

  • Completed Phase 2 in Conjunctival Allergen Challenge (CAC) model as proof of concept (POC) for ocular surface inflammation

  • Positive POC for ocular surface activity in reducing redness and demonstrated anti-inflammatory effect

  • IC 265 concentrations were found well tolerated in the Phase 2 study


  • Manufacturing clinical supplies for Good Manufacturing Practice (GMP)

Clinical Development

  • Open Investigational New Drug (IND) application with US FDA

  • Planned Phase 2 parallel-group study in dry eye patients
