EC1456 (Folate-Tubulysin) Cancer*
Designed to deliver a highly potent chemotherapy drug to folate-receptor-positive cancers
EC1456 is an investigational, proprietary, injectable SMDC consisting of folate (vitamin B9) linked to a potent cytotoxic agent, tubulysin B hydrazide (TubBH). EC1456 is wholly owned by Endocyte. TubBH is a member of the tubulysin class of anti-neoplastic agents that inhibits the polymerization of tubulin into microtubules, a critical component during cell division. EC1456 is the first SMDC with TubBH to enter clinical trials.
EC1456 is being co-developed with etarfolatide as its companion imaging agent.
EC1456 is currently being evaluated in a phase 1 study in patients with advanced solid tumors.
