The development pipeline

Merging global experience and technology to offer patients a brighter future

To promote our network-based drug discovery and global R&D efforts, Santen is placing significant emphasis on strengthening our relationships with universities, research organisations and other pharmaceutical firms to conceive new treatments for patients around the world. We hope such relationships will lead to the discovery and launch of novel therapies for severe dry eye disease, glaucoma, diabetic macular oedema and uveitis, a condition with limited treatment options.
