Ganitumab and Metformin plus Standard Neoadjuvant Therapy in Stage 2/3 Breast Cancer: Results from the I-SPY2 Adaptively Randomized Platform Trial

Project description:Ganitumab and Metformin was one of the experimental regiments evaluated in I-SPY 2, a neoadjuvant platform trial for high risk, early stage breast cancer. Based on the hypotheses that pre-treatment IGF-1R axis signaling at the expression level may predict response to Ganitumab and Metformin, in pre-defined analyses we assessed 11 genes involved in IGF1R pathway signaling, the IGFBP5/IGFBP4 ratio, and two IGFR expression signatures to test their association with pCR (complete pathologic response).

Neoadjuvant T-DM1/pertuzumab and paclitaxel/trastuzumab/pertuzumab for HER2-positive breast cancer in the adaptively randomized I-SPY2 trial.

Project description:Ado-trastuzumab emtansine plus pertuzumab (T-DM1/P) and paclitaxel plus trastuzumab and pertuzumab (THP) are two of the experimental regiments evaluated in I-SPY 2, a neoadjuvant platform trial for high risk, early stage breast cancer. In pre-defined analyses we assessed 10 biomarkers at the pre-treatment timepoint in the HER2, ER/PR, and proliferation pathways to test their association with pCR (complete pathologic response).

I-SPY2-990 mRNA/RPPA Data Resource: RPPA component

Project description:The RPPA component of the I-SPY2-990 mRNA/RPPA Data Resource contains protein/phosphoprotein data from pre-treatment laser capture microdissected (LCM) tumor biopsies for 139 key signaling proteins/phosphoproteins in cancer for 736 patients from 8 arms of the neoadjuvant I-SPY2 TRIAL (NCT01042379) for aggressive early stage breast cancer [194 Control (Ctr); 63 veliparib/carboplatin (VC); 105 neratinib (N); 87 MK2206; 128 trebananib; 49 TDM1/pertuzumab(P); 43 H/P; and 67 pembrolizumab (pembro)]. This record also contains clinical data for these patients, including HR, HER2 and MP status, response (pCR or no pCR), and treatment arm. RPPA endpoints assayed are from hormone receptor (n=4), HER family (n=14), cell cycle/proliferation (n=20), immune (n=18), DNA repair deficiency (DDR; n=15), AKT/mTOR/PI3K (n=7), apoptosis/autophagy (n=10), IGF1R (n=6), TIE/ANG (n=4), growth/survival/metabolism (n=22) and RTK (n=19) pathways. For gene expresson data for all 736 patients with RPPA data, plus an additional 150 patients for a total 987 patients from 10 arms of I-SPY2 (mRNA component of the I-SPY2-990 Data Resource), see the companion GEO record/subseries GSE194040.

I-SPY2-990 mRNA/RPPA Data Resource: mRNA component

Project description:The I-SPY2-990 mRNA/RPPA Data Resource contains gene expression and clinical data for 987 patients from 10 arms of the neoadjuvant I-SPY2 TRIAL for aggressive early stage breast cancer [210 Control (Ctr); 71 veliparib/carboplatin (VC); 114 neratinib (N); 93 MK2206; 106 ganitumab; 93 ganetespib; 134 trebananib; 52 TDM1/pertuzumab(P); 44 H/P; 69 pembrolizumab (pembro)]. All 987 patients have pretreatment full transcriptome expression data on over ~19,000 genes assayed on Agilent 44K. Clinical data includes HR, HER2 and MP status, response (pCR or no pCR), and treatment arm. The ISPY2-990 mRNA/RPPA Data Resource also includes normalized pre-treatment LCM-RPPA data for 139 key signaling proteins/phosphoproteins in cancer for 736 patients (see companion GEO record GSE196093 for data and details).

Durvalumab with olaparib and paclitaxel for high-risk HER2-negative stage II/III breast cancer: Results from the adaptively randomized I-SPY2 platform trial

Project description:Durvalumab with olaparib was one of the experimental regimens evaluated in I-SPY 2, a neoadjuvant platform trial for high risk, early stage breast cancer, and graduated in the HER2- and HR+HER2- signatures. We hypothesized that (pre-treatment) expression-based immune signatures may predict response to the immune checkpoint inhibitor durvalumab and signatures related to DNA repair deficiency (DRD) may associate with response to olaparib. In this analysis, we assessed 13 expression based signatures related to immune, DRD, proliferation and estrogen signaling as specific predictor of pathologic complete response (pCR) to durvalumab/olaparib.
