Official title

A Phase II Study Evaluating Safety and Efficacy of Niraparib in Patients With Previously Treated Homologous Recombination (HR) Defective or Loss of Heterozygosity (LOH) High Metastatic Esophageal/Gastroesophageal Junction/Proximal Gastric Adenocarcinoma

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Patients can be prescreened for the study at the time of diagnosis of locally advanced or metastatic disease by determining presence of LOH high status and/or deleterious alterations in HR pathway genes in the most recent available tumor tissue sample or in blood if they are found to have germline mutations. Patients with either somatic or germline mutations will be allowed. At the time of disease progression, patients with high LOH or deleterious alterations in HR pathway genes and satisfying all other inclusion criteria will be enrolled on the study. Patients will be treated with niraparib (flat dose) orally every day for 28 days until disease progression, unacceptable side effects, withdrawal of consent, or death. CT of the chest/abdomen/pelvis will be performed every 2 months and response will be assessed by RECIST 1.1.
