ALK2 inhibitors display beneficial effects in preclinical models of ACVR1 mutant diffuse intrinsic pontine glioma.
Carvalho, D; Taylor, KR; Olaciregui, NG; Molinari, V; Clarke, M; et al. (NATURE PUBLISHING GROUP, 2019-05-09)Diffuse intrinsic pontine glioma (DIPG) is a lethal childhood brainstem tumour, with a quarter of patients harbouring somatic mutations in ACVR1, encoding the serine/threonine kinase ALK2. Despite being an amenable drug ... -
Combined MYC and P53 defects emerge at medulloblastoma relapse and define rapidly progressive, therapeutically targetable disease.
Hill, RM; Kuijper, S; Lindsey, JC; Petrie, K; Schwalbe, EC; et al. (CELL PRESS, 2015-01-12)We undertook a comprehensive clinical and biological investigation of serial medulloblastoma biopsies obtained at diagnosis and relapse. Combined MYC family amplifications and P53 pathway defects commonly emerged at relapse, ... -
Dual blockade of the PI3K/AKT/mTOR (AZD8055) and RAS/MEK/ERK (AZD6244) pathways synergistically inhibits rhabdomyosarcoma cell growth in vitro and in vivo.
Renshaw, J; Taylor, KR; Bishop, R; Valenti, M; De Haven Brandon, A; et al. (AMER ASSOC CANCER RESEARCH, 2013-08-05)PURPOSE: To provide rationale for using phosphoinositide 3-kinase (PI3K) and/or mitogen-activated protein kinase (MAPK) pathway inhibitors to treat rhabdomyosarcomas, a major cause of pediatric and adolescent cancer deaths. ... -
p53 Loss in MYC-Driven Neuroblastoma Leads to Metabolic Adaptations Supporting Radioresistance.
Yogev, O; Barker, K; Sikka, A; Almeida, GS; Hallsworth, A; et al. (AMER ASSOC CANCER RESEARCH, 2016-09-29)Neuroblastoma is the most common childhood extracranial solid tumor. In high-risk cases, many of which are characterized by amplification of MYCN, outcome remains poor. Mutations in the p53 (TP53) tumor suppressor are rare ... -
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 ... -
Repurposing Vandetanib plus Everolimus for the Treatment of ACVR1-Mutant Diffuse Intrinsic Pontine Glioma.
Carvalho, DM; Richardson, PJ; Olaciregui, N; Stankunaite, R; Lavarino, C; et al. (AMER ASSOC CANCER RESEARCH, 2022-02-01)Somatic mutations in ACVR1 are found in a quarter of children with diffuse intrinsic pontine glioma (DIPG), but there are no ACVR1 inhibitors licensed for the disease. Using an artificial intelligence-based platform to ... -
Triplet Therapy with Palbociclib, Taselisib, and Fulvestrant in PIK3CA-Mutant Breast Cancer and Doublet Palbociclib and Taselisib in Pathway-Mutant Solid Cancers.
Pascual, J; Lim, JSJ; Macpherson, IR; Armstrong, AC; Ring, A; et al. (AMER ASSOC CANCER RESEARCH, 2021-01-01)Cyclin-dependent kinase 4/6 (CDK4/6) and PI3K inhibitors synergize in PIK3CA-mutant ER-positive HER2-negative breast cancer models. We conducted a phase Ib trial investigating the safety and efficacy of doublet CDK4/6 ...
