VYNFINIT® (Vintafolide) Cancer*

Designed to target the folate receptor to deliver potent chemotherapy

Vynfinit® (Vintafolide) delivers a potent vinca alkaloid chemotherapy directly to cancer cells by targeting the folate receptor expressed on cancer cells, but not on most normal cells. Approximately 80–90% of ovarian and lung cancers express the receptor, as do many other types of cancer. Folate receptor status is determined by a Folcepri® (99mTc-etarfolatide) scan.

Development Stage

Platinum-resistant ovarian cancer:

  • Vynfinit® is being evaluated in a global Phase 3 study named PROCEED for women with platinum-resistant ovarian cancer.
  • Vynfinit®has also been evaluated in the PRECEDENT study, a randomized Phase 2 trial comparing Vynfinit® + PLD (DOXIL) versus PLD (DOXIL) alone in women with platinum-resistant ovarian cancer.  This study has been completed and published.

Non-small cell lung cancer:

  • Vynfinit®is also being investigated in a Phase 2b study named TARGET in patients with non-small cell lung cancer (NSCLC). Results are pending.

Future clinical trials:

  • Vynfinit® will be evaluated in women with triple-negative breast cancer in a Phase 2b study scheduled to begin in 2014.

Merck Partnership

Endocyte and Merck entered into a $1 billion partnership for Vynfinit® in April 2012. Under this partnership, we granted Merck an exclusive license to develop, manufacture, and commercialize Vynfinit®. Endocyte will co-promote Vynfinit® in the United States upon approval by the United States Food and Drug Administration. We are responsible for conducting the PROCEED Phase 3 clinical study in women with platinum resistant ovarian cancer and the Phase 2b second line NSCLC study. Merck is responsible for further clinical studies in additional potential indications
