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.

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.

Eligibility

Inclusion Criteria:

• Histologically or cytologically documented Stage IV NSCLC not amenable to curative surgery or radiation.

Patients must have tumors that lack activating EGFR mutations and ALK fusions.

• (WHO)/(ECOG) performance status of 0 or 1

• No prior chemotherapy or any other systemic therapy for Stage IV NSCLC

• Adequate organ and marrow function without blood transfusions in the past 28 days,

• At least 1 tumor lesion, not previously irradiated, that can be accurately measured as per RECIST 1.1.

Key Inclusion criteria for randomization to maintenance treatment:

• Documented radiographic evidence of CR, PR, or Stable Disease (SD) as per Investigator-assessed RECIST 1.1 following 4 cycles of platinum-based chemotherapy.

• Creatinine Clearance (CrCl) =51 mL/min calculated by the investigator or designee using the Cockcroft-Gault equation or measured by 24-hour urine collection.

• Ability to swallow whole oral medications.

• All patients must provide a formalin-fixed, paraffin embedded tumor sample for tissue-based immunohistochemistry staining and DNA sequencing to determine PD-L1 expression, HRRm status, and other correlatives: either newly acquired or archival tumor samples (<3 years old) are acceptable. If available, a newly acquired tumor biopsy, collected as part of routine clinical practice, is preferred. If not available, an archival sample taken <3 years prior to screening is acceptable. If both an archival sample and a fresh tumor biopsy sample are available, both samples should be submitted for analysis and must be submitted as different samples using different accession numbers. Slides from different blocks cannot be mixed and submitted with the same kit.

Secondary	Change From Baseline in European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ)-Lung Cancer (LC)13	Disease-related symptoms assessed by change from baseline (for maintenance phase) in EORTC QLQ-LC13. Average adjusted mean over first 11 cycles is presented.; The EORTC QLQ-LC13 was scored according to the published scoring manual. An outcome variable consisting of a score from 0 to 100 was derived for each of the symptom scales in the EORTC QLQ-LC13. Higher scores on symptom scales represent greater symptom severity.	From randomization until date of objective radiological disease progression or death, or last evaluable assessment in the absence of progression, up to 18 months
Secondary	Time to Deterioration in European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ)-Lung Cancer (LC)13	Disease-related symptoms assessed by time to deterioration (for maintenance phase) in European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ)-Lung Cancer (LC)13.; Symptom deterioration is defined as an increase in the score from baseline of less than or equal to 10) that is confirmed at a subsequent assessment, or death (by any cause) in the absence of a clinically meaningful symptom deterioration.; NA is "not applicable". The upper confidence limit was not calculable because of an insufficient number of participants with events.	From randomization until date of objective radiological disease progression or death, or last evaluable assessment in the absence of progression, up to 18 months
Secondary	Change From Baseline in EORTC Quality of Life Questionnaire (QLQ) QLQ-C30	Disease-related symptoms and health-related quality of life (HRQoL) assessed by change from baseline (for maintenance phase) in EORTC QLQ-C30. Average adjusted mean over first 11 cycles is presented.; The EORTC QLQ-C30 was scored according to the published scoring manual. An outcome variable consisting of a score from 0 to 100 was derived for each of the symptom scales, each of the function scales, and the global health status/QoL scale in the EORTC QLQ-C30. Higher scores on the global health status and function scales indicate better health status/function.; A high scale score represents a higher response level. Thus a high score for a functional scale represents a high / healthy level of functioning, a high score for the global health status / quality of life (QoL) represents a high QoL, but a high score for a symptom scale / item represents a high level of symptomatology / problems.	Includes all assessments occurring within the first 12 months of randomization or until disease progression, up to 18 months.
Secondary	Time to Deterioration in EORTC Quality of Life Questionnaire (QLQ) QLQ-C30	Disease-related symptoms and health-related quality of life (HRQoL) assessed by time to deterioration (for maintenance phase) in EORTC QLQ-C30.; NA is "not applicable". The upper confidence limit was not calculable because of an insufficient number of participants with events.	From randomization until date of first symptom deterioration that is confirmed, up to 18 months.
Secondary	Presence of Anti-drug Antibodies (ADAs) for Durvalumab	Presence of anti-drug antibodies (ADAs) for durvalumab, as assessed at 3, 6, 12, 16 and 20 weeks after start of treatment and every 12 weeks thereafter until 3 and 6 months after last dose of durvalumab	Assessed from start of initial therapy up to 2 years.
Secondary	Number of Participants With Treatment-Related Adverse Events	Number of Participants with Treatment-Related Adverse Events as Assessed by Common Terminology Criteria for Adverse Events (CTCAE)	From randomization until date of objective radiological disease progression or death, or last evaluable assessment in the absence of progression, up to 18 months
