Its pafolacianine, sold as Cytalux, was approved by the FDA in 2021 for ovarian cancer and in 2022 for lung lesions, the first targeted fluorescent imaging agents for intraoperative use, and the company is developing further folate receptor and other targeted optical agents. OnCo links it to ovarian and non-small-cell lung cancer, fluorescence-guided surgery and optical imaging, and to the pafolacianine record. Whether finding more deposits during surgery improves outcomes, not just completeness of resection, is the open question. Pafolacianine has its own page.","asOf":"2026-09-10","links":[{"label":"Official website","url":"https://ontargetlabs.com"}],"tags":[],"related":[],"cancers":["ovarian","nsclc"],"sections":["imaging","surgery"],"technologies":["fluorescence-guided-surgery","optical-imaging"],"targets":[],"drugs":["pafolacianine"],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"hq":"West Lafayette, IN","country":"US","companyType":"imaging","website":"https://ontargetlabs.com","founded":2010,"stage":"startup","investors":["jjdc"],"funding":[]},"route":"/companies/on-target-laboratories/","neighbours":{"cancer":[{"id":"nsclc","kind":"cancer","name":"Non-small-cell lung cancer","route":"/cancers/nsclc/"},{"id":"ovarian","kind":"cancer","name":"Ovarian cancer","route":"/cancers/ovarian/"}],"section":[{"id":"imaging","kind":"section","name":"Imaging","route":"/fronts/imaging/"},{"id":"surgery","kind":"section","name":"Surgery & Interventional","route":"/fronts/surgery/"}],"technology":[{"id":"fluorescence-guided-surgery","kind":"technology","name":"Fluorescence-guided surgery","route":"/technologies/fluorescence-guided-surgery/"},{"id":"intraoperative-fluorescence-imaging-systems","kind":"technology","name":"Intraoperative fluorescence and Cerenkov imaging systems (SPY, Firefly, LumiSystem, LightPath)","route":"/technologies/intraoperative-fluorescence-imaging-systems/"},{"id":"optical-imaging","kind":"technology","name":"Optical & fluorescence imaging","route":"/technologies/optical-imaging/"}],"drug":[{"id":"pafolacianine","kind":"drug","name":"Pafolacianine","route":"/drugs/pafolacianine/"}],"company":[{"id":"jjdc","kind":"company","name":"Johnson & Johnson Innovation - JJDC","route":"/companies/jjdc/"}],"trial":[{"id":"nct04241315","kind":"trial","name":"ELUCIDATE: Enabling Lung Cancer Identification Using Folate Receptor Targeting","route":"/trials/nct04241315/"}]}}
