Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This is a retrospective international, multi-center, non-interventional cohort study based on use of data derived from established medical records and secondary analysis of archival tumor samples. The study will collect data on patient and tumor characteristics, PD-L1 status, patterns of treatment, and clinical outcomes, in up to 600 adult patients with recurrent/metastatic SCCHN. SCCHN of interest for this study are defined as the diseases falling into specific ICD-10 or International Classification of Diseases, Ninth Revision (ICD-9) codes (Table 1), depending on anatomical sub-site of the primary tumor.
For patient selection, the date of diagnosis of recurrent/metastatic disease will be used as the index date. The patient selection period extends from the 1st March 2011 to the 30th June 2015. This allows for the inclusion of patients with tumor samples of approximately ≤ 5 years age, and ensures approximately 10 months follow-up for living patients recruited at last day of the enrollment window. All patients with a diagnosis of recurrent/metastatic SCC of the oral cavity (tongue, gum, floor of mouth, and other/unspecified part of the mouth), oropharynx, hypopharynx, or larynx during that period will be considered for inclusion in the study (Figure 1). Patients will be identified and followed up through their medical records until death or end of data collection in approximately 20 centers in the US, Asia and Europe.
Patients' demographic, clinical characteristics, and medical history will be described. Clinical outcomes including PFS, best response, duration of response, and ORR will be described for the first line and second line of therapy (if any), and OS will be collected A mandatory archived tumor samples will be used to determine PD-L1 status. If a patient has more than one suitable tissue sample, the most recent sample will be used as the mandatory tissue sample. Where available, additional tumor samples obtained at any other time points of the disease will be also collected (optional).
The enrolment target is up to 600 patients. Statistical analyses will be performed for the whole cohort, per PD-L1 status and for predefined subgroups.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Background/Rationale:
Programmed cell death protein 1 (PD-1) is an immune inhibitory receptor that interacts with two ligands, programmed death ligand 1 (PD-L1) and ligand 2 (PD-L2). PD-1 pathway is a major immune checkpoint which has been implicated in adaptive immune resistance of squamous cell carcinoma of the head and neck (SCCHN) tumors, particularly in those associated with human papillomavirus (HPV) infection. Based on an internal analysis performed by AstraZeneca (AZ), it is reported that approximately 25% of cases of SCCHN express PD-L1. Tumoral PD-L1 expression status correlates closely with response to anti-PD-1/anti PD-L1 antibodies Durvalumab (MEDI4736) is an immunoglobulin G1 kappa monoclonal antibody with high affinity and selectivity for PD-L1 and no binding to PD-L2, which is in development for the treatment of patients with recurrent or metastatic SCCHN.
This non-interventional study (NIS) aims to generate and provide data on the prognostic value of PD-L1 status in patients with recurrent/metastatic SCCHN.
Objectives and Hypotheses:
Primary objective:
To determine the prognostic value of PD-L1 status in terms of overall survival (OS) in patients with recurrent/metastatic SCCHN. Overall survival after diagnosis of recurrent/metastatic SCCHN will be assessed in PD-L1 positive and PD-L1 negative patients and in predefined sub-groups (e.g., HPV status, HIV status, smoking history, heavy alcohol use, anatomical sub-site of primary tumor, and prior exposure to radiation therapy).
Secondary objectives:
Secondary objectives are to perform the following in a) all patients meeting the eligibility criteria, b) all patients per availability of tumor sample (not available, available at any setting), and c) all patients with available tumor sample at any time, at the time of first line therapy, or at the second line therapy per PD-L1 status (positive, negative, unknown/not done):
1. To describe the relevant demographic and clinical characteristics of patients, stratified by PD-L1 status
2. To describe first line treatment choices, and where available, subsequent treatment choices
3. To describe investigator-assessed tumor response for first line and second line of therapy (if any), including: best response, duration of response where applicable, and objective response rate (ORR)
4. To describe investigator-assessed progression-free survival (PFS) for first line and second line of therapy (if any).
Exploratory objectives:
1. To perform additional biomarker research on tumor samples (depending on tissue availability and volume).
2. If feasible, to assess agreement of PD-L1 status in samples obtained at different time points (e.g., before and after chemotherapy or radiation therapy).
Methods:
Study design:
This is a retrospective international, multi-center, non-interventional cohort study based on use of data derived from established medical records and secondary analysis of archival tumor samples. The study will collect data on patient and tumor characteristics, PD-L1 status, patterns of treatment, and clinical outcomes, in up to 600 adult patients with recurrent/metastatic SCCHN.
For patient selection, the date of diagnosis of recurrent/metastatic disease will be used as the index date. The patient selection period extends from the 1st March 2011 to the 30th June 2015. This allows the inclusion of patients with tumor samples of approximately ≤ 5 years age, and ensures approximately 10 months follow-up for living patients recruited at last day of the enrolment window. All patients with a diagnosis of recurrent/metastatic squamous cell carcinoma (SCC) of oral cavity (tongue, gum, floor of mouth, and other/unspecified part of the mouth), oropharynx, hypopharynx, or larynx during that period will be considered for inclusion in the study. Patients will be identified and followed up through their medical records until death or end of data collection (approximately Q4 2016).
Patients' demographic and clinical characteristics, and medical history will be described. Clinical outcomes including PFS, best response, duration of response, and ORR will be described for the first and second lines of therapy(if any), and OS will be collected. A mandatory archived tumor sample will be used to determine PD-L1 status. If a patient has more than one suitable tissue sample, the most recent sample will be used as the mandatory tissue sample. Where available, additional tumor samples obtained at any other time points of the disease will be also collected (optional).
Statistical analyses will be performed for the whole cohort, per PD-L1 status and for predefined subgroups.
Data Source(s):
The study will be implemented in a total of approximately 20 sites in the US, Asia and Europe. Data will be abstracted from patient's hospital medical records until death, or end of data collection. Archival tumor samples will be retrieved and tested by immunohistochemistry to assess the PD-L1 status of the tumor. Where there is sufficient tissue quantity, the expression of other biomarkers will also be evaluated.
Study Population:
Unselected patient population representative of patients who may receive MEDI4736 in the real life setting.
Exposure(s): The primary variable is the PD-L1 status (positive or negative) in the overall patient population. Archived tissue samples, including samples from the primary site, lymph nodes or distant metastatic sites, will be used to determine PD-L1 status. PD-L1 status will be determined by immunohistochemistry (IHC) using a validated assay.
Outcome(s):
Overall survival will be assessed. Additionally, the following clinical outcomes will be described for first line and second line treatments for recurrent and/or metastatic disease: investigator-assessed best tumor response, duration of response where applicable, and investigator-assessed PFS. ORR (sum of complete and partial responses) will be derived from investigator-assessed best responses and described for first line and second line therapies (if any).
Patient characteristics, disease characteristics, and patterns of treatment will be captured and described.
Sample Size Estimation:
The primary objective of this study is to estimate the prognostic value of PD-L1 status in terms of OS in patients with recurrent/metastatic SCCHN. The available sample size is not known a priori and will be driven by the number of patients at selected sites with available tissue. However, assuming that PD-L1 status distribution is approximately 25% positive and 75% negative status, that the median OS in these patients is 10 months, that the study will accrue uniformly over 52 months with 10 months follow-up from the last patient entering and that survival times are exponentially distributed, the illustrations of hazard ratios it would be possible to detect with 80% power (2-sided alpha 0.05) over various sample sizes are given in the table below.
HR to detect Number of deaths Number of patients (Total) 0.3 30 40 0.4 51 68 0.5 74 112 0.6 136 196 0.7 278 396 HR: Hazard ratio These illustrations do not take account of the fact that the binary prognostic factor of interest (PD-L1 status) may be correlated with other covariates and hence could over-estimate the power of the various sample sizes (Bernardo et al, 2000). The sample size (number of events) required when no correlation is assumed should be multiplied by 1/(1-R2) to account for an R2 \> 0 (Hsieh and Lavori, 2000). The correlation is not currently known. Additionally, a proportion of patients will not have PD-L1 status available. Given these uncertainties, a sample size of up to 600 patients is felt to be adequate.
Statistical Analysis:
Descriptive analyses on patient characteristics, treatment choices and treatment outcomes will be conducted.
Time to event data (OS, PFS) including rates of affected patients will be assessed described using the Kaplan-Meier method. Two-sided 95% CIs will be provided for the main statistical estimators.
OS and PD-L1 status will be described in subgroups, including but not limited to the following:
* Per anatomical sub-site of primary tumor
* Per HPV status
* Per HIV status
* Per smoking history
* Per alcohol consumption history
* Per prior exposure to radiation therapy
* Per types of treatment regimens
* By performance status at diagnosis of recurrent/metastatic disease. The prognostic value of PD-L1 status will be investigated using a Cox proportional hazards model. Additional covariates to be included in the model will be described in the statistical analysis plan.
