"NKTR-102 is emerging as a promising anti-cancer investigational treatment with the potential to become the first topoisomerase I-inhibitor to be used in the fight against breast cancer," said Prof. Ahmad Awada, Head of the Medical Oncology Clinic at the Institut Jules Bordet in Brussels, Belgium. "The drug's high confirmed objective response rate and clinical benefit is very interesting, particularly when one observes that this response rate was maintained in patients pre-treated with anthracyclines, taxanes with or without capecitabine, and also maintained in poor prognosis subsets within the study, such as triple-negative breast cancer and patients with visceral disease."
The confirmed ORR in patients previously treated with anthracycline/taxane/capecitabine was 31% (5/16); confirmed ORR in patients with metastatic triple-negative breast cancer was 39% (7/18); and confirmed ORR in patients with visceral disease was 30% (17/57).
"The every three week dose schedule appears well-tolerated overall and demonstrates encouraging PFS and OS of 5.3 months and 13.1 months, respectively," continued Dr. Awada. "We are in need of effective new therapeutic options whose mechanism of action is different from those already available for women with metastatic breast cancer and we look forward to NKTR-102 entering Phase 3 development."
Patients treated in the single-agent NKTR-102 study had a median of two lines of prior cytotoxic treatments for metastatic disease. Seventy-four percent (52/70) of the patients received neoadjuvant and/or adjuvant therapy and 86% (60/70) had visceral disease.
"The clinical benefit we've observed in multiple tumor settings with NKTR-102, where a highly active topoisomerase 1 inhibitor could be extremely useful, makes us very excited a
