The drug, Eskata, would be the first FDA-approved non-invasive treatment for the condition, Aclaris said.
Seborrheic keratoses are non-cancerous skin growths that affect more than 83 million American adults, according to Aclaris.

Eskata is expected to be commercially available in the spring of 2018.
Shares of Malvern, Pennsylvania-based Aclaris rose 9.2% to $24.72 in premarket trading.
