Artificial intelligence and radiomics biomarkers for treatment response prediction in advanced HER2-negative breast cancer
Article
Author: Schwartz, Lawrence H ; Schmitt, Julia ; Zhao, Binsheng ; Dercle, Laurent ; Amend, Mario ; McGale, Jeremy ; Peltzer, Alexander
STUDY AIM:
Despite the development of novel therapies, breast cancer mortality remains high. Improved treatment response assessment tools are needed. We aimed to test the transferability of externally validated AI/radiomics biomarkers for predicting treatment response in advanced, hormone receptor-positive (HR+), HER2-breast cancer treated with xentuzumab, exemestane, and everolimus.
METHODS:
Patient data from a phase Ib/II trial (May 2014-October 2016) were analyzed retrospectively. Eight imaging biomarkers (liver and overall tumor volume, two radiomics features representing tumor heterogeneity at both baseline and week 8) were validated for predicting clinical benefit using AUC analysis. An ancillary AI analysis developed a signature for predicting best overall response using 40 variables (3 clinical and 37 imaging) in the same cohort.
RESULTS:
Of 106 patients with data available for analysis, 28 had no clinical benefit from treatment (Group A) vs. 78 with clinical benefit (Group B). Seven of eight imaging biomarkers demonstrated significant predictive value. Participants in Group B exhibited significantly lower baseline and follow-up measures of liver and overall tumor volume, alongside marked changes in tumor heterogeneity by week 8. In our ancillary AI/radiomics model, the dominant drivers of prediction were changes in both liver tumor and overall tumor volume during treatment and the number of osteoblastic lesions on baseline bone scans.
CONCLUSION:
This cross-cancer proof-of-concept testing study supports the feasibility of applying multimodal AI/radiomics biomarkers to predict treatment response in advanced HR+, HER2- breast cancer, laying the foundation for broader pancancer and pantreatment applications pending further validation.

Phase Ib study of xentuzumab and abemaciclib in patients with advanced solid tumors and in combination with endocrine therapy in patients with advanced breast cancer
Article
Author: Yee, D. ; Oliveira, M. ; Puig, M. ; Gonçalves, A. ; Sablin, M.P. ; Vidal, M. ; Lorence, R.M. ; Fukuyama, Y. ; LoRusso, P. ; Forman, N. ; Hardebeck, M.C. ; Stradella, A. ; Iwata, H.
BACKGROUND:
This phase Ib trial assessed the insulin-like growth factor 1/2 neutralizing antibody, xentuzumab, plus abemaciclib ± endocrine therapy (ET) in patients with advanced/metastatic solid tumors, including hormone receptor (HR)-positive breast cancer.
PATIENTS AND METHODS:
In part 1, patients with advanced solid tumors received escalating doses of xentuzumab + abemaciclib (cohort A). In part 2, dose-finding cohorts B-D had advanced/metastatic HR-positive, human epidermal growth factor receptor 2-negative breast cancer and received xentuzumab + abemaciclib plus letrozole, anastrozole, or fulvestrant. Part 3 included expansion cohorts assessing xentuzumab + abemaciclib plus fulvestrant in patients with HR-positive, human epidermal growth factor receptor 2-negative breast cancer with visceral (cohort D1) or non-visceral disease (cohort D2) who had progressed following ET, or non-visceral disease who had progressed following ET and a cyclin-dependent kinase inhibitor (cohort F). Primary endpoints were maximum tolerated dose (cohorts A-D), 18-month progression-free survival (cohort D1/D2) and disease control (cohort F). Comprehensive biomarker analyses were undertaken.
RESULTS:
A total of 133 patients were treated. The maximum tolerated dose was xentuzumab 1000 mg once weekly plus abemaciclib 150 mg twice daily (cohorts A-D). The most common grade ≥3 adverse event was decreased neutrophil count. Cohorts B-D demonstrated response rates of ≥25%. The 18-month progression-free survival rate in cohorts D1/D2 was 41.4%/78.5%. The disease control rate in cohort F was 40.0%. Biomarker analysis indicated target engagement. Prognostic biomarkers included total serum insulin-like growth factor 1 concentrations, expression of CCND1, and MCL-1 mutations.
CONCLUSIONS:
Xentuzumab + abemaciclib + ETs demonstrated manageable tolerability and promising efficacy, especially in patients with breast cancer and non-visceral metastases.

Abstract:
Management of hepatoblastoma (HB), the most frequent pediatric liver cancer, is based on surgical resection and perioperative chemotherapy regimens. In this study, we aimed to identify actionable targets in HB and assess the efficacy of molecular therapies in preclinical models of HB. Paired tumor and adjacent tissues from 31 HBs and a validation set of 50 HBs were analyzed using RNA-seq, SNP, and methylation arrays. IGF2 overexpression was identified as the top targetable HB driver, present in 71% of HBs (22/31). IGF2high tumors displayed progenitor cell features and shorter recurrence-free survival. IGF2 overexpression was associated in 91% of cases with fetal promoter hypomethylation, ICR1 deregulation, 11p15.5 loss of heterozygosity or miR483-5p overexpression. The antitumor effect of xentuzumab (a monoclonal antibody targeting IGF1/2) alone or in combination with the conventional therapeutic agent cisplatin was assessed in HB cell lines, in PDX-derived HB organoids and in a xenograft HB murine model. The combination of xentuzumab with cisplatin showed strong synergistic antitumor effects in organoids and in IGF2high cell lines. In mice (n = 55), the combination induced a significant decrease in tumor volume and improved survival compared with cisplatin alone. These results suggest that IGF2 is an HB actionable driver and that, in preclinical models of HB, the combination of IGF1/2 inhibition with cisplatin induces superior antitumor effects than cisplatin monotherapy. Overall, our study provides a rationale for testing IGF2 inhibitors in combination with cisplatin in HB patients with IGF2 overexpression.
