Study of Durvalumab+Olaparib or Durvalumab After Treatment With Durvalumab and Chemotherapy in Patients With Lung Cancer (ORION) — ORION  

Non-small Cell Lung Cancer NSCLC Clinical Trial

Official title: A Phase II Randomized, Multi-Center, Double-Blind, Global Study to Determine the Efficacy and Safety of Durvalumab Plus Olaparib Combination Therapy Compared With Durvalumab Monotherapy as Maintenance Therapy in Patients Whose Disease Has Not Progressed Following Standard of Care Platinum-Based Chemotherapy With Durvalumab in First Line Stage IV Non Small Cell Lung Cancer (ORION)

Status Active, not recruiting

Clinical Trial Summary

This is a randomized, double-blind, multi-center, global Phase II study to determine the efficacy and safety of Durvalumab plus Olaparib combination therapy compared with Durvalumab monotherapy as maintenance therapy in patients whose disease has not progressed following Standard of Care (SoC) platinum-based chemotherapy with Durvalumab as first-line treatment in patients with Stage IV non small-cell lung cancer (NSCLC) with tumors that lack activating epidermal growth factor receptor (EGFR) mutations and anaplastic lymphoma kinase (ALK) fusions.

Clinical Trial Description

Adult patients with a histologically or cytologically documented advanced NSCLC not amenable to curative surgery or radiation with tumors that lack activation EGFR mutations and ALK fusions are eligible for enrollment. During the initial therapy phase, patients will receive treatment with Durvalumab along with the Investigator's choice of platinum-based doublet therapy for squamous NSCLC (nab-paclitaxel plus carboplatin or gemcitabine plus carboplatin/cisplatin) and non-squamous NSCLC (nab-paclitaxel plus carboplatin or pemetrexed plus carboplatin/cisplatin) for 4 cycles. Patients who have completed 4 cycles and not progressed throughout the initial therapy phase will be randomized in a 1:1 ratio into the maintenance phase of the study to receive either Durvalumab plus placebo or Durvalumab plus Olaparib maintenance therapy. Patients will receive maintenance treatment until specific discontinuation criteria are met, including clinical disease progression (as assessed by the Investigator) or RECIST 1.1-defined radiological Progressive Disease (PD), unacceptable toxicity, and withdrawal of consent. Tumor evaluation scans will be performed until objective disease progression as efficacy assessments. All patients will be followed for survival until the end of the study. ;
