Overview

Aptamer Sciences is a South Korean biotech listed on KOSDAQ that develops cancer treatments and diagnostic tools built around aptamers, short, lab-engineered molecules that bind tightly to specific biological targets, similar in concept to antibodies.

Its lead drug-development platform, called ApDC®, links aptamers to cancer-killing agents to create targeted therapies for solid and blood cancers, which the company aims to license out to larger pharmaceutical partners after establishing clinical proof of concept. Alongside drug development, it provides analytical testing services for biopharmaceuticals, including antibody drugs and peptides, to pharma companies and biotech ventures, and holds a diagnostic product designed to assess lung-cancer risk from blood protein markers.
