A Global Study to Assess the Effects of MEDI4736 Following Concurrent Chemoradiation in Patients With Stage III Unresectable Non-Small Cell Lung Cancer

Proportion of Patients Alive and Progression Free at 12 Months From (APF12) Based on BICR Assessments According to RECIST 1.1

APF12 was defined as the percentage of patients who were alive and progression free per RECIST 1.1 at 12 months after randomization per Kaplan-Meier estimate of PFS at 12 months.

Time frame: Tumor scans performed at baseline then every ~8 weeks up to 48 weeks, then every ~ 12 weeks thereafter until confirmed disease progression. Assessed until 13 Feb 2017 DCO; up to a maximum of approximately 3 years.

Proportion of Patients Alive and Progression Free at 18 Months From (APF18) Based on BICR Assessments According to RECIST 1.1

APF18 was defined as the percentage of patients who were alive and progression free per RECIST 1.1 at 18 months after randomization per the Kaplan-Meier estimate of PFS at 18 months.

Time frame: Tumor scans performed at baseline then every ~8 weeks up to 48 weeks, then every ~ 12 weeks thereafter until confirmed disease progression. Assessed until 13 Feb 2017 DCO; up to a maximum of approximately 3 years.

Time to Death or Distant Metastasis (TTDM) Based on BICR Assessments According to RECIST 1.1

TTDM was defined as the time from the date of randomization until the first date of distant metastasis or death in the absence of distant metastasis. Distant metastasis was defined as any new lesion that was outside of the radiation field according to RECIST 1.1 or proven by biopsy. TTDM was calculated using the Kaplan-Meier technique.

Time frame: Tumor scans performed at baseline then every ~8 weeks up to 48 weeks, then every ~ 12 weeks thereafter until confirmed disease progression. Assessed until 22 Mar 2018 DCO; up to a maximum of approximately 4 years.

Percentage of Patients Alive at 24 Months (OS24)

OS24 was defined as the percentage of patients who were alive at 24 months after randomization per the Kaplan-Meier estimate of OS at 24 months.

Time frame: From baseline until death due to any cause. Assessed until 22 Mar 2018 DCO; up to a maximum of approximately 4 years.

Time to Second Progression or Death (PFS2)

PFS2 was defined as the time from randomization to the time of the second progression or death. The date of second progression was recorded by the investigator and defined according to local standard clinical practice, and could have involved any of the following: objective radiological, symptomatic progression, or death. RECIST assessments were not collected for assessment of PFS2. PFS2 was calculated using the Kaplan-Meier technique.

Time frame: Following confirmed progression, patients were assessed every ~12 weeks until second disease progression. Assessed until 22 Mar 2018 DCO; up to a maximum of approximately 4 years.

Time to Deterioration of Global Health Status / Health-Related Quality of Life (HRQoL), Assessed Using European Organization for Research and Treatment of Cancer 30-Item Core Quality of Life Questionnaire (EORTC QLQ-C30)

Global health status/HRQoL was assessed using the EORTC QLQ-C30 global QoL scale which includes 2 items from the QLQ-C30: "How would you rate your overall health during the past week?" (Item 29) and "How would you rate your overall QoL during the past week?" (Item 30). Scores from 0 to 100 were derived for each item with higher scores indicating a better health status. Time to deterioration for global health status/HRQoL was defined as time from randomization until the date of first clinically meaningful deterioration (a decrease in global health status/HRQoL from baseline of ≥10) or death (by any cause) in the absence of a clinically meaningful deterioration. Time to deterioration was calculated using the Kaplan-Meier technique.

Time frame: 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 until 22 Mar 2018 DCO; up to a maximum of approximately 4 years.

Time to Deterioration of Primary Patient-Reported Outcome (PRO) Symptoms, Assessed Using European Organization for Research and Treatment of Cancer QoL Lung Cancer Module (EORTC QLQ-LC13)

The EORTC QLQ-LC13 is a lung cancer specific module from the EORTC comprising 13 questions to assess lung cancer symptoms (cough, hemoptysis, dyspnea, chest pain, arm/shoulder pain, and other pain), treatment related side-effects (sore mouth, dysphagia, peripheral neuropathy and alopecia) and pain medication. Scores from 0 to 100 were derived for each symptom item with higher scores representing greater symptom severity. Time to symptom deterioration was defined as time from randomization until the date of first clinically meaningful symptom deterioration (an increase in the score from baseline of ≥10) or death (by any cause) in the absence of a clinically meaningful symptom deterioration. Results are presented for time to deterioration in the following PRO endpoints identified as primary for EORTC QLQ-LC13: dyspnea, cough, hemoptysis and chest pain. Time to deterioration was calculated using the Kaplan-Meier technique.

Time frame: 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 until 22 Mar 2018 DCO; up to a maximum of approximately 4 years.

Pharmacokinetics (PK) of Durvalumab; Peak and Trough Serum Concentrations

To evaluate PK, blood samples were collected pre-dose and post-dose and trough and peak serum concentrations of durvalumab, respectively, were determined. Pre-dose samples were taken within 60 minutes before infusion and post-dose samples were taken within 10 minutes after the end of infusion.

Time frame: Samples were collected pre-dose on Day 1 (Week 0), Week 8, Week 24 and Week 48, and post-dose on Day 1 (Week 0) and Week 24. Analysis performed at 22 Mar 2018 DCO.

Number of Patients With Anti-Drug Antibody (ADA) Response to Durvalumab

ADA positive post-baseline only was also referred to as treatment-induced ADA positive. Treatment-boosted ADA was defined as baseline positive ADA titer that was boosted by ≥4-fold following drug administration. Persistently positive was defined as positive at ≥2 post-baseline assessments (with ≥16 weeks between first and last positive) or positive at last post-baseline assessment. Transiently positive was defined as having at least 1 post-baseline ADA positive assessment and not fulfilling the conditions of persistently positive. Confirmed ADA positive samples were subsequently tested in a neutralizing antibody assay.

Time frame: Samples were collected pre-dose on Day 1 (Week 0), Week 8, Week 24 and Week 48. Analysis performed at 22 Mar 2018 DCO.
