Description:
This is a multicentre, multinational Phase Ib study in female HR+ MBC patients not receiving
Her2-targeted therapy. Treatment consists of a chemo-immunotherapy phase followed by a
maintenance phase. The chemo-immunotherapy phase consists of 6 cycles of 4 weeks each. During
each cycle the subject will receive 80 mg/m2 paclitaxel intravenously on Day 1, 8 and 15 and
30 mg efti subcutaneously on Day 1 and 15 in a 28-day (4-week) cycle. Efti will always be
given after paclitaxel. The maintenance phase comprises 6 visits with 4 weekly intervals;
during each such visit 30 mg efti is given subcutaneously as monotherapy. A total of 24
subjects will be enrolled into the study. The primary goal of the study is safety and
tolerability profile of efti in combination with weekly paclitaxel both given the same day in
contrast to subsequent days as in the AIPAC trial.
