About Us
Qlaris Bio is a clinical stage biotechnology company founded on a relentless commitment to develop innovative first-in-class therapies that can make a truly impactful change for patients suffering from serious and debilitating ophthalmic diseases.
Our Approach
We are exploring novel mechanisms of action to address the largest unmet needs in ophthalmology.
Our Science
Our lead asset, QLS-111, has a unique vasodilatory mechanism of action and is designed to lower intraocular pressure (IOP) by reducing episcleral venous pressure (EVP) and distal outflow resistance beyond the trabecular meshwork. By reducing EVP, and distal outflow resistance, QLS-111 has the potential to enable the achievement of lower IOP targets than available therapies currently allow.
QLS-111 is currently in development for the treatment of Normal Tension Glaucoma, Primary Open-Angle Glaucoma, Ocular Hypertension, and elevated IOP associated with rare diseases such as Sturge-Weber Syndrome.
