PARP inhibitors like olaparib have revealed clinical benefit in TNBC harboring BRCA germline mutations, but were ineffective when tested as monotherapy for BRCA WT metastatic breast cancer. While combining a PARP inhibitor with chemotherapy may be beneficial, such therapy is limited by bone marrow toxicity. Methods: In the phase 2 PETREMAC trial (NCT02624973), we assessed the efficacy of primary olaparib monotherapy for 10 weeks, followed by chemotherapy, in TNBC (T > 2 cm). Tumor biopsies and blood leucocytes for targeted DNA sequencing of 360 cancer-related genes were collected prior to therapy and after 10 weeks on olaparib. Results: 31 patients with TNBC were included (mean tumor size 59 mm; range 33-97). Olaparib monotherapy was well tolerated, yielding a clinical CR in 5 and a PR in 15 patients (all-over objective response rate; ORR 64%). Olaparib had no major impact on subsequent chemotherapy toxicity. The average pretreatment mutation rate was 3.3 indels/point mutations per tumor with no differences in mutation burden recorded between responders and non-responders or BRCA carriers vs. non-carriers. Among five patients harboring pathogenic BRCA1/2 mutations (4 germline, 1 somatic) all responded to olaparib, and n ¼ 3/5 obtained pathological complete response. Interestingly, mutations in genes associated with DNA damage repair (ATRX, BRCA1/ 2, EMSY, MSH6, PARP10, PPM1D) occurred in n ¼ 9/20 olaparib responders, but in none of the 11 non-responders (p ¼ 0.011). Non-responders were characterized by mutations in oncogenic pathways (PIK3CA, AKT1, KRAS, IGF2R, NF2 and TGFBR2) in 7 out of 11 tumors (P ¼ 0.00013). No significant association was observed between TP53 mutations (recorded in 23/31 tumors) and response to olaparib. Targeted DNA sequencing is ongoing for biopsies taken after 10 weeks of olaparib monotherapy; the results will be presented. Conclusions: Olaparib yielded a high response rate when administered to treatmentnaı¨ve, large TNBC, indicating a potential role in sequential neoadjuvant therapy, for patients both with and without BRCA1/2 germline mutations.

Immunological differences between immune-rich estrogen receptorpositive and -negative breast cancers
T. O’Meara1, M. Marczyk1, K. Blenman1, V. Yaghoobi2, V. Pelenkanou3, D. Rimm2, L. Pusztai4 1 Medical Oncology, Yale University School of Medicine, New Haven, CT, USA, 2 Pathology, Yale University School of Medicine, New Haven, CT, USA, 3Pathology, Sanofi, Cambridge, AL, USA, 4Medical Oncology, Yale University School of Medicine, New Haven, CT, USA Background: A subset of estrogen receptor-positive (ERþ) breast cancers have significant tumor infiltrating lymphocytes (TILs), similar to triple-negative breast cancer (TNBC). We examined differences in the immune microenvironment of immune-rich ERþ and immune-rich TNBC to find out if similar or different immunotherapy strategies are appropriate for these distinct disease types. Methods: ERþ/HER2-negative and TNBC cases were obtained from The Cancer Genome Atlas (TCGA) (n ¼ 818 RNA Seq) and METABRIC (n ¼ 1465 microarray). An immune gene expression score, as surrogate for TILs, was calculated for each case (Danaher et al). Signature scores were correlated with histologic TILs (R ¼ 0.44, p < 0.001) for available cases. All cases in the top 25% of signature scores were considered immune-rich. We compared 22 immune cell populations between immune-rich TNBC (n ¼ 86) and ER þ (n¼119) using CIBERSORT (Student’s t-test, FDR adjusted). We examined differential expression of 770 immune-related genes and 137 immunooncology (IO) drug targets. Macrophage abundance was measured by quantitative immunofluorescence (QIF) using pan-macrophage marker CD68 in 169 TNBC and 87 ERþ FFPE tissues. Results: In TCGA and METABRIC, CIBERSORT showed more M0 (p ¼ 0.015, p ¼ 0.0043) and M1 macrophages (p ¼ 9.4e-08, p ¼ 6.24e-11) in immune-rich TNBC compared to ERþ. Mast cells (p ¼ 0.0093, p ¼ 4.09e-15) and M2 macrophages (p ¼ 4.4e-05, p ¼ 0.053) were more abundant in immune-rich ERþ. QIF confirmed higher macrophage content in TNBC (p ¼ 0.0001). In both datasets, 36 IO targets were higher expressed in TNBC and 15 in ERþ cases (Table). Notably, coordinated high expression of TGFb pathway members TGFb3, TGFb-R2, and LRRC32 was seen in ERþ cancers and correlated positively with M2 and negatively with M1 macrophage content across all cases. Conclusions: IO drugs targeting TGFb, M2 macrophages and mast cells are attractive therapeutic candidates in immune-rich ERþ breast cancer based on the expression characteristics of these targets.
