A Real-world Study of Durvalumab for Lung Cancer in China

A Real-world Study of Consolidation Durvalumab for Stage III Unresectable Non-small Cell Lung Cancer in China and Safety Data on Durvalumab in Chinese Patients With Lung Cancer（PACIFIC-PUMCH-R）

PACIFIC-PUMCH-R is an ambispective cohort study that will enroll approximately 100 patients with lung cancer who have received at least one dose of durvalumab between July 2020 and July 2021. Patient selection and data collection will be from Peking Union Medical College Hospital.

Cohort 1 will include patients with unresectable stage III non-small cell lung cancer (according to the Staging Manual in Thoracic Oncology, version 7, of the International Association for the Study of Lung Cancer) who did not have disease progression after concurrent chemoradiotherapy. The primary objective of Cohort 1 is to assess the effectiveness of durvalumab in a real-life setting by evaluating PFS and OS in Chinese patients.

Cohort 2 will enroll patients with histologically or cytologically confirmed NSCLC or SCLC who have received chemotherapy/radiotherapy at the physician's discretion. And this Cohort aimed to assess the safety of durvalumab for the treatment of lung cancer in clinical practice.

Description

Inclusion Criteria:

15. Current or prior use of immunosuppressive medication within 14 days before the first dose of durvalumab or tremelimumab. The following are exceptions to this criterion:

    • Intranasal, inhaled, topical steroids or local steroid injections (eg, intra articular injection).
    • Systemic corticosteroids at physiologic doses not to exceed 10 mg/day of prednisone or its equivalent.
    • Steroids as premedication for hypersensitivity reactions (eg, CT scan premedication). Premedication with steroids for chemotherapy is acceptable. Systemic steroid administration required to manage toxicities arising from radiation therapy delivered as part of the chemoradiation therapy for locally advanced NSCLC is allowed
16. Participation in another clinical study with an IP during the last 4 weeks
17. Previous enrolment or randomisation in the present study
18. Concurrent enrollment in another clinical study, unless it is an observational (non-interventional) clinical study or during the follow-up period of an interventional study

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Progression-free Survival (Cohort 1)	PFS is defined as time from the index date (date of the first dose of durvalumab) to the date of the first documentation of progressive disease (PD) or death from any cause, whichever occurs first. Per RECIST 1.1 modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ, PD is defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. Note: The appearance of one or more new lesions is also considered PD.	Tumor scans performed at baseline then every ~8 weeks up to 48 weeks, then every ~12 weeks thereafter until confirmed disease progression. Assessed up to a maximum of approximately 3 years
Overall Survival (Cohort 1)	OS is defined as the time from randomization to the time of death from any cause.	From baseline until death due to any cause. Assessed up to a maximum of approximately 4 years.
Number of Participants With one or more Adverse Events (Cohort 2)	Adverse events (AE) are graded using the Common Terminology Criteria for Adverse Events (CTCAE) v4.0. Grade refers to the severity of the AE. The CTCAE v4.0 assigns Grades 1 through 5 with unique clinical descriptions of severity for each AE based on this general guideline: Grade 1 Mild AE, Grade 2 Moderate AE, Grade 3 Severe AE, Grade 4 Life-threatening or disabling AE, Grade 5 Death related to AE.	Baseline until up to 90 days after end of treatment.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Objective response rate (Cohort 1)	Objective response is defined as best overall response (CR or PR) across all assessment timepoints during the period from enrolment to termination of trial treatment.	Tumor scans performed at baseline then every ~8 weeks up to 48 weeks, then every ~12 weeks thereafter until confirmed disease progression. Assessed up to a maximum of approximately 4 years.
Duration of Response (Cohort 1)	For participants who demonstrated CR or PR, DOR is defined as the time from the first documented evidence of CR or PR until PD or death from any cause, whichever occurs first. Per RECIST 1.1 modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ, or death from any cause, PD is defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm.	Tumor scans performed at baseline then every ~8 weeks up to 48 weeks, then every ~12 weeks thereafter until confirmed disease progression. Assessed up to a maximum of approximately 4 years.
Time to death or distant metastasis (Cohort 1)	TTDM will be defined as the time from the index date (date of the first dose of durvalumab) to the first date of distant metastasis or death in the absence of distant metastasis.	Tumor scans performed at baseline then every ~8 weeks up to 48 weeks, then every ~12 weeks thereafter until confirmed disease progression. Assessed up to a maximum of approximately 4 years.
Time from the index date to second progression (Cohort 1)	PFS2 will be defined as the time from the index date to the earliest of the progression event subsequent to that used for the PFS endpoint or death.	Following confirmed progression, patients were assessed every ~12 weeks until second disease progression. Assessed up to a maximum of approximately 4 years.
Number of Participants With one or more Adverse Events (Cohort 1)	Adverse events (AE) are graded using the Common Terminology Criteria for Adverse Events (CTCAE) v4.0. Grade refers to the severity of the AE.	Baseline until up to 90 days after end of treatment.
Change from Baseline in European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30 (QLQ-C30) Global Health Status/Quality of Life	The EORTC QLQ-C30 is a questionnaire to assess the overall quality of life of cancer patients. The EORTC Quality of Life Questionnaire and Lung Cancer Module 13 (QLQ-LC13) is a supplemental lung cancer-specific module used in combination with QLQ-C30. An increase in combined score indicates improvement in quality of life.	At baseline, every 4 weeks for first 8 weeks, then every ~8 weeks until 48 weeks, then every ~12 weeks thereafter until confirmed disease progression. Assessed up to a maximum of approximately 4 years.
Progression-free Survival (Cohort 2)	PFS is defined as time from the index date (date of the first dose of durvalumab) to the date of the first documentation of progressive disease (PD) or death from any cause, whichever occurs first. Per RECIST 1.1 modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ, PD is defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. Note: The appearance of one or more new lesions is also considered PD.	Tumor scans performed at baseline then every ~8 weeks up to 48 weeks, then every ~12 weeks thereafter until confirmed disease progression. Assessed up to a maximum of approximately 3 years.
Overall Survival (Cohort 2)	OS is defined as the time from randomization to the time of death from any cause.	From baseline until death due to any cause. Assessed up to a maximum of approximately 4 years.
Objective response rate (Cohort 2)	Objective response is defined as best overall response (CR or PR) across all assessment timepoints during the period from enrolment to termination of trial treatment.	Tumor scans performed at baseline then every ~8 weeks up to 48 weeks, then every ~12 weeks thereafter until confirmed disease progression. Assessed up to a maximum of approximately 4 years.
