A decade of clinical development of PARP inhibitors in perspective.
Mateo, J; Lord, CJ; Serra, V; Tutt, A; Balmaña, J; et al. (ELSEVIER, 2019-09-01)Genomic instability is a hallmark of cancer, and often is the result of altered DNA repair capacities in tumour cells. DNA damage repair defects are common in different cancer types; these alterations can also induce ... -
A Wolf in Sheep's Clothing: Systemic Immune Activation Post Immunotherapy.
Tiu, C; Shinde, R; Pal, A; Biondo, A; Lee, A; et al. (Innovative Healthcare Institute, 2021-11-01)INTRODUCTION: Immune checkpoint inhibitors (ICIs) are increasingly a standard of care for many cancers; these agents can result in immune-related adverse events (irAEs) including fever, which is common but can rarely be ... -
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 ... -
Circulating Cell-Free DNA to Guide Prostate Cancer Treatment with PARP Inhibition.
Goodall, J; Mateo, J; Yuan, W; Mossop, H; Porta, N; et al. (AMER ASSOC CANCER RESEARCH, 2017-09-01)Biomarkers for more precise patient care are needed in metastatic prostate cancer. We have reported a phase II trial (TOPARP-A) of the PARP inhibitor olaparib in metastatic prostate cancer, demonstrating antitumor activity ... -
DNA-Repair Defects and Olaparib in Metastatic Prostate Cancer.
Mateo, J; Carreira, S; Sandhu, S; Miranda, S; Mossop, H; et al. (MASSACHUSETTS MEDICAL SOC, 2015-10-29)BACKGROUND: Prostate cancer is a heterogeneous disease, but current treatments are not based on molecular stratification. We hypothesized that metastatic, castration-resistant prostate cancers with DNA-repair defects would ... -
A HUWE1 defect causes PARP inhibitor resistance by modulating the BRCA1-∆11q splice variant.
Pettitt, SJ; Shao, N; Zatreanu, D; Frankum, J; Bajrami, I; et al. (SPRINGERNATURE, 2023-09-01)Although PARP inhibitors (PARPi) now form part of the standard-of-care for the treatment of homologous recombination defective cancers, de novo and acquired resistance limits their overall effectiveness. Previously, ... -
Patient-derived organoids model treatment response of metastatic gastrointestinal cancers.
Vlachogiannis, G; Hedayat, S; Vatsiou, A; Jamin, Y; Fernández-Mateos, J; et al. (AMER ASSOC ADVANCEMENT SCIENCE, 2018-02-23)Patient-derived organoids (PDOs) have recently emerged as robust preclinical models; however, their potential to predict clinical outcomes in patients has remained unclear. We report on a living biobank of PDOs from ... -
Phase I Trial of First-in-Class ATR Inhibitor M6620 (VX-970) as Monotherapy or in Combination With Carboplatin in Patients With Advanced Solid Tumors.
Yap, TA; O'Carrigan, B; Penney, MS; Lim, JS; Brown, JS; et al. (AMER SOC CLINICAL ONCOLOGY, 2020-06-22)PURPOSE: Preclinical studies demonstrated that ATR inhibition can exploit synthetic lethality (eg, in cancer cells with impaired compensatory DNA damage responses through ATM loss) as monotherapy and combined with DNA-damaging ... -
Phase I Trial of the PARP Inhibitor Olaparib and AKT Inhibitor Capivasertib in Patients with BRCA1/2- and Non-BRCA1/2-Mutant Cancers.
Yap, TA; Kristeleit, R; Michalarea, V; Pettitt, SJ; Lim, JSJ; et al. (AMER ASSOC CANCER RESEARCH, 2020-10-01)Preclinical studies have demonstrated synergy between PARP and PI3K/AKT pathway inhibitors in BRCA1 and BRCA2 (BRCA1/2)-deficient and BRCA1/2-proficient tumors. We conducted an investigator-initiated phase I trial utilizing ... -
RNAi screen reveals synthetic lethality between cyclin G-associated kinase and FBXW7 by inducing aberrant mitoses.
Dolly, SO; Gurden, MD; Drosopoulos, K; Clarke, P; de Bono, J; et al. (NATURE PUBLISHING GROUP, 2017-09-26)BACKGROUND: F-box and WD40 repeat domain-containing 7 (FBXW7) is an E3 ubiquitin ligase involved in the ubiquitination and degradation of multiple oncogenic substrates. The tumour suppressor function is frequently lost in ... -
Second-Generation HSP90 Inhibitor Onalespib Blocks mRNA Splicing of Androgen Receptor Variant 7 in Prostate Cancer Cells.
Ferraldeschi, R; Welti, J; Powers, MV; Yuan, W; Smyth, T; et al. (AMER ASSOC CANCER RESEARCH, 2016-05-01)Resistance to available hormone therapies in prostate cancer has been associated with alternative splicing of androgen receptor (AR) and specifically, the expression of truncated and constitutively active AR variant 7 ... -
