WEST LAFAYETTE, IN, USA I March 21, 2014 I Endocyte, Inc. (ECYT) today announced results from the Phase 2b TARGET trial, which showed that the study met the primary endpoint for the combination of vintafolide (EC145/MK-8109) and docetaxel in folate receptor (FR)-positive recurrent non-small cell lung cancer (NSCLC) patients. As a randomized Phase 2b study, the pre-defined statistical threshold for significance was a p-value of
The TARGET Phase 2b trial was conducted in 199 patients, randomized to one of three arms: vintafolide alone, vintafolide/docetaxel combination, or docetaxel alone. Secondary endpoints, including overall response rate and OS, also showed trends in favor of the combination arm. Median OS has been reached for the vintafolide and docetaxel single-agent arms but has not yet been reached in the combination arm. In addition, the investigational combination regimen showed better activity in patients with adenocarcinoma, a subset analysis pre-specified in the trial design.
The safety profile of the combination arm was consistent with those observed with docetaxel alone and vintafolide alone, though a higher rate of hematologic and peripheral neuropathy adverse events were observed in the combination arm. There were no drug-related deaths in the combination arm. Single-agent vintafolide at the schedule evaluated in this study demonstrated less activity than single-agent docetaxel.
“We are pleased with the results of this study, as the vintafolide/docetaxel combination showed meaningful activity in patients with recurrent NSCLC, meeting the primary endpoint of the trial,” said Binh Nguyen, M.D., Ph.D., vice president of medical affairs at Endocyte. “This is our second randomized study in a very challenging indication, where vintafolide has met the primary endpoint when used in patients selected with the companion imaging agent etarfolatide. These results provide further validation of our targeted approach to treatment using companion imaging and our SMDC technology. We were especially pleased with the results in the adenocarcinoma population and early OS trends, and we have learned important information about the dosing schedule. We look forward to reviewing additional analysis of this study when the OS data has matured later this year to help inform potential further development of the vintafolide/docetaxel combination in NSCLC.”
“We are encouraged by the results from the TARGET trial which show activity with vintafolide in these difficult-to-treat patients, and look forward to reviewing still maturing data from TARGET later this year,” said Dr. Eric Rubin, vice president, clinical development for oncology, Merck Research Laboratories.

About the TARGET trial
TARGET is an international, multicenter, open-label Phase 2b study designed to evaluate vintafolide in patients with stage IIIb or IV NSCLC with all lesions positive for the folate receptor (FR 100%) as determined by the investigational companion imaging agent etarfolatide (EC20) and who have failed one prior chemotherapy (ClinicalTrials.gov Identifier: NCT01577654). Secondary endpoints include the comparison of overall response rate, disease control rate, duration of response, duration of disease control, overall survival of the participants between treatment arms, and the incidence of adverse and serious adverse events. TARGET included three investigational arms, vintafolide monotherapy and vintafolide in combination with docetaxel, each of which was compared to a standard-of-care control arm, docetaxel monotherapy.
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-etarfolatideetarfolatide for 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. Further evaluation is ongoing in the global PROCEED Phase 3 clinical trial in folate receptor-positive (FR 100%) platinum-resistant ovarian cancer (ClinicalTrials.gov Identifier: NCT01170650). The randomized TARGET Phase 2b study of vintafolide in non-small cell lung cancer has completed enrollment (ClinicalTrials.gov Identifier: NCT01577654), and a Phase 2 study in triple-negative breast cancer is expected to be initiated in Q2 (ClinicalTrials.gov Identifier: NCT01953536).
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.
