BMG Genomics: An ancestry informative marker panel design for individual ancestry estimation of Hispanic population using whole exome sequencing data

December 30, 2019

Li-Ju Wang, Catherine W. Zhang, Sophia C. Su, Hung-I H. Chen, Yu-Chiao Chiu, Zhao Lai, Hakim Bouamar, Amelie G. Ramirez, Francisco G. Cigarroa, Lu-Zhe Sun & Yidong Chen Abstract Background Europeans and American Indians were the major genetic ancestry of Hispanics in the U.S. These ancestral groups have markedly different incidence rates and outcomes in many types of cancers. Therefore, the genetic admixture may cause a […]

Frontiers in Oncology: Nanoformulation of Talazoparib Increases Maximum Tolerated Doses in Combination With Temozolomide for Treatment of Ewing Sarcoma

December 17, 2019

The Pediatric Preclinical Testing Program previously identified the PARP inhibitor talazoparib (TLZ) as a means to potentiate temozolomide (TMZ) activity for the treatment of Ewing sarcoma. However, the combination of TLZ and TMZ has been toxic in both preclinical and clinical testing, necessitating TMZ dose reduction to ~15% of the single-agent maximum tolerated dose. We […]

Briefings in Bioinformatics: Deep learning of pharmacogenomics resources: moving towards precision oncology

December 8, 2019

Yu-Chiao Chiu, Hung-I Harry Chen, Aparna Gorthi, Milad Mostavi, Siyuan Zheng, Yufei Huang, Yidong Chen Abstract The recent accumulation of cancer genomic data provides an opportunity to understand how a tumor’s genomic characteristics can affect its responses to drugs. This field, called pharmacogenomics, is a key area in the development of precision oncology. Deep learning (DL) methodology has emerged as a […]

Pediatric Blood & Cancer: Phase 1/2 trial of talazoparib in combination with temozolomide in children and adolescents with refractory/recurrent solid tumors including Ewing sarcoma: A Children’s Oncology Group Phase 1 Consortium study (ADVL1411)

November 14, 2019

Abstract Purpose We conducted a phase 1/2 trial of the poly(ADP‐ribose) polymerase 1/2 inhibitor talazoparib in combination with low‐dose temozolomide (TMZ) to determine the dose‐limiting toxicities (DLTs), recommended phase 2 dose (RP2D), and pharmacokinetics of this combination in children with recurrent/refractory solid tumors; and to explore clinical activity in Ewing sarcoma (EWS) (NCT02116777). Methods Talazoparib […]
