Biomarkers Associating with PARP Inhibitor Benefit in Prostate Cancer in the TOPARP-B Trial.
Carreira, S; Porta, N; Arce-Gallego, S; Seed, G; Llop-Guevara, A; et al. (AMER ASSOC CANCER RESEARCH, 2021-11-01)PARP inhibitors are approved for treating advanced prostate cancers (APC) with various defective DNA repair genes; however, further studies to clinically qualify predictive biomarkers are warranted. Herein we analyzed ... -
CD38 in Advanced Prostate Cancers.
Guo, C; Crespo, M; Gurel, B; Dolling, D; Rekowski, J; et al. (ELSEVIER, 2021-02-01)BACKGROUND: CD38, a druggable ectoenzyme, is involved in the generation of adenosine, which is implicated in tumour immune evasion. Its expression and role in prostate tumour-infiltrating immune cells (TIICs) have not been ... -
Characterizing CDK12-Mutated Prostate Cancers.
Rescigno, P; Gurel, B; Pereira, R; Crespo, M; Rekowski, J; et al. (AMER ASSOC CANCER RESEARCH, 2020-09-28)PURPOSE: Cyclin-dependent kinase 12 (CDK12) aberrations have been reported as a biomarker of response to immunotherapy for metastatic castration-resistant prostate cancer (mCRPC). Herein, we characterize CDK12-mutated ... -
Clinical Utility of Circulating Tumour Cell Androgen Receptor Splice Variant-7 Status in Metastatic Castration-resistant Prostate Cancer.
Sharp, A; Welti, JC; Lambros, MBK; Dolling, D; Rodrigues, DN; et al. (ELSEVIER, 2019-11-01)BACKGROUND: Detection of androgen receptor splice variant-7 (AR-V7) mRNA in circulating tumour cells (CTCs) is associated with worse outcome in metastatic castration-resistant prostate cancer (mCRPC). However, studies ... -
HER3 Is an Actionable Target in Advanced Prostate Cancer.
Gil, V; Miranda, S; Riisnaes, R; Gurel, B; D'Ambrosio, M; et al. (AMER ASSOC CANCER RESEARCH, 2021-12-15)It has been recognized for decades that ERBB signaling is important in prostate cancer, but targeting ERBB receptors as a therapeutic strategy for prostate cancer has been ineffective clinically. However, we show here that ... -
JMJD6 Is a Druggable Oxygenase That Regulates AR-V7 Expression in Prostate Cancer.
Paschalis, A; Welti, J; Neeb, AJ; Yuan, W; Figueiredo, I; et al. (AMER ASSOC CANCER RESEARCH, 2021-02-15)Endocrine resistance (EnR) in advanced prostate cancer is fatal. EnR can be mediated by androgen receptor (AR) splice variants, with AR splice variant 7 (AR-V7) arguably the most clinically important variant. In this study, ... -
Molecular and immunological features of a prolonged exceptional responder with malignant pleural mesothelioma treated initially and rechallenged with pembrolizumab.
Minchom, A; Yuan, W; Crespo, M; Gurel, B; Figueiredo, I; et al. (BMJ PUBLISHING GROUP, 2020-03-01)BACKGROUND: This case represents an exceptional response to pembrolizumab in a patient with epithelioid mesothelioma with a further response on rechallenge. CASE PRESENTATION: A 77-year-old woman with advanced epithelioid ... -
Olaparib in patients with metastatic castration-resistant prostate cancer with DNA repair gene aberrations (TOPARP-B): a multicentre, open-label, randomised, phase 2 trial.
Mateo, J; Porta, N; Bianchini, D; McGovern, U; Elliott, T; et al. (ELSEVIER SCIENCE INC, 2020-01-01)BACKGROUND: Metastatic castration-resistant prostate cancer is enriched in DNA damage response (DDR) gene aberrations. The TOPARP-B trial aims to prospectively validate the association between DDR gene aberrations and ... -
Phase 1, dose-escalation study of guadecitabine (SGI-110) in combination with pembrolizumab in patients with solid tumors.
Papadatos-Pastos, D; Yuan, W; Pal, A; Crespo, M; Ferreira, A; et al. (BMJ PUBLISHING GROUP, 2022-06-01)BACKGROUND: Data suggest that immunomodulation induced by DNA hypomethylating agents can sensitize tumors to immune checkpoint inhibitors. We conducted a phase 1 dose-escalation trial (NCT02998567) of guadecitabine and ... -
Single-Cell Analyses of Prostate Cancer Liquid Biopsies Acquired by Apheresis.
Lambros, MB; Seed, G; Sumanasuriya, S; Gil, V; Crespo, M; et al. (AMER ASSOC CANCER RESEARCH, 2018-11-15)Purpose: Circulating tumor cells (CTCs) have clinical relevance, but their study has been limited by their low frequency.Experimental Design: We evaluated liquid biopsies by apheresis to increase CTC yield from patients ... -
Targeting the p300/CBP Axis in Lethal Prostate Cancer.
Welti, J; Sharp, A; Brooks, N; Yuan, W; McNair, C; et al. (AMER ASSOC CANCER RESEARCH, 2021-05-01)Resistance to androgen receptor (AR) blockade in castration-resistant prostate cancer (CRPC) is associated with sustained AR signaling, including through alternative splicing of AR (AR-SV). Inhibitors of transcriptional ... -
