Endocyte to Present Data on EC1456 and Etarfolatide at American Society of Clinical Oncology (ASCO) Annual Meeting 2014

(May 19, 2014)

WEST LAFAYETTE, Ind., May 19, 2014 (GLOBE NEWSWIRE) -- Endocyte, Inc. (Nasdaq:ECYT) a biopharmaceutical company and leader in developing targeted small molecule drug conjugates (SMDCs) and companion imaging agents for personalized therapy in cancer and other serious diseases, today announced that two poster presentations featuring Endocyte's SMDC EC1456 and companion imaging agent etarfolatide will be presented at the 50th Annual Meeting of the American Society of Clinical Oncology (ASCO) being held May 30 - June 3, 2014, in Chicago.



The EC1456 poster shows the design and dosing schedule of the Phase 1 dose-escalation study of Endocyte's wholly-owned folate receptor (FR)-targeting folate-tubulysin conjugate, EC1456, in adult patients with advanced solid tumors.



The second poster presentation entitled "Real-time Identification of Tumor Lesions Likely to Respond to Vintafolide Treatment" shows the capability of etarfolatide to correctly identify in real-time nearly all tumor lesions that responded to folate-targeted therapy, whereas lesions that do not demonstrate etarfolatide uptake did not demonstrate major shrinkage following vintafolide treatment. The researchers evaluated 209 baseline lesions from patients in a Phase 2 open-label, multicenter study of the investigational agent vintafolide in advanced ovarian cancer (ClinicalTrials.gov Identifier: NCT00507741).
























































Presentations are as follows:

About Vintafolide, Etarfolatide and IV Folic Acid




Vintafolide is an investigational conjugate of folic acid (vitamin B9) linked to an anti-cancer agent, the potent vinca alkaloid desacetylvinblastine hydrazide (DAVLBH). Since cancer cells generally consume higher levels of folate than normal cells to fuel their growth, some cancer cell types - including ovarian and NSCLC - have high concentrations of the folate receptor on their surface. Vintafolide is designed to selectively target the folate receptor to deliver the anti-cancer agent to the cancerous tissue. Tumors that have high concentrations of the folate receptor are identified by etarfolatide, a non-invasive imaging diagnostic agent. Intravenous folic acid is used with 99mTc-etarfolatidefor the enhancement of image quality.



Vintafolide, etarfolatide and IV folic acid have been granted orphan drug status by the EMA. The U.S. Food and Drug Administration has also granted orphan drug status to vintafolide and etarfolatide.



About EC1456



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 inhibit the polymerization of tubulin into microtubules, a critical component during cell division. The targeting ligand folate, essential for cell division, has been investigated with vintafolide. EC1456 is currently being evaluated in a Phase 1 study in patients with advanced solid tumors (ClinicalTrials.gov Identifier: NCT01999738).



About Endocyte



Endocyte is a biopharmaceutical company and leader in developing targeted small molecule drug conjugates (SMDCs) and companion imaging agents for personalized therapy in cancer and other serious diseases. Endocyte uses its proprietary technology to create novel SMDCs and companion imaging agents for personalized targeted therapies. The company's SMDCs actively target receptors that are expressed or over-expressed on diseased cells, relative to healthy cells. This targeted approach is designed to enable the treatment of patients with highly potent drugs into these cells. The companion imaging agents are designed to identify patients whose disease expresses the molecular target of the therapy and who therefore may be more likely to benefit from treatment.
