Fig. 3From: A phase Ib study of pictilisib (GDC-0941) in combination with paclitaxel, with and without bevacizumab or trastuzumab, and with letrozole in advanced breast cancerWaterfall plot of maximum percentage changes from baseline in SLD for target lesions. Maximum percentage changes are shown in (a) part 1 (pictilisib + paclitaxel ± bevacizumab), (b) parts 2A and B (2A: pictilisib + paclitaxel; 2B: pictilisib + paclitaxel + bevacizumab), (c) part 2C (pictilisib + paclitaxel + trastuzumab), and (d) part 3 (pictilisib + letrozole). PTEN categories were defined as PTEN loss (PTEN H-score ≥ 0 but ≤ 100) or nonloss (PTEN H-score > 100).
