Ipsen announces preliminary results of phase I trial in metastatic breast cancer with BN83495

The compound is currently in further clinical development for advanced endometrial cancer (phase II) as well as in Phase I clinical evaluation for castrate resistant prostate cancer in North America.

Professor R. Charles Coombes, Imperial College, Clinical Professor, Division of Surgery, Oncology, Reproductive Biology and Anaesthetics London, UK, lead author of the poster said: "To date, four of the patients who received BN83495 had tumours that remained stable for at least 6 months. One of these had cutaneous metastases that improved after one month of treatment. This is very encouraging, as these women are patients who are reaching the end of their hormonal treatment options. Importantly, BN83495 was well tolerated at the selected dose.” He added: “I am confident that BN83495 will become a new hormonal option in the treatment of post-menopausal women with ER-positive metastatic breast cancer".

Stéphane Thiroloix, Executive Vice-President, Corporate Development commented: “Metastatic breast cancer clearly deserves R&D effort to identify new hormonal agents that can delay disease progression and prolong overall survival. Following this important clinical milestone, we look forward to progressing the global development of BN83495 in this indication and in other selected hormone-dependent cancer indications. ”
