An AE was occurrence of an undesirable medical condition or the deterioration of a pre-existing medical condition following or during exposure to a pharmaceutical product or device, whether or not considered causally related to the product or device medical occurrence in a participant. The TEAEs of pneumonitis were defined as any pneumonitis event that occurred or worsened at any time after the start of administration of the first dose of durvalumab and through 30 days after the last dose of durvalumab. Severity (intensity of any event) was assessed using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse events (CTCAE) v5. The AEs were assigned to a Grade from 1 through 5 as follows: Grade 1: Mild; Grade 2: Moderate; Grade 3: Severe or medically significant but not immediately life-threatening requiring hospitalization; Grade 4: Life-threatening consequences; Grade 5: Death due to any AE.

The SAF included all enrolled participants who took at least 1 dose of durvalumab.

Pulmonary TEAEs were defined as any pulmonary AEs that occurred or worsened at any time after the start of administration of the first dose of durvalumab and through 30 days after the last dose of durvalumab. Number of participants with permanent discontinuation of durvalumab due to pulmonary TEAEs including pneumonitis are reported.

The SAF included all enrolled participants who took at least 1 dose of durvalumab.

The overall duration of durvalumab treatment, while participants were a part of this wearable study, was calculated as end date of durvalumab treatment minus first dose of durvalumab (Day 1) plus 1.

The SAF included all enrolled participants who took at least 1 dose of durvalumab.

Number of participants who discontinued durvalumab early due to any reason are reported.

The SAF included all enrolled participants who took at least 1 dose of durvalumab.

Treatment interruptions were defined as at least 1 temporary withholding of durvalumab treatment. Treatment withheld was defined as temporarily withheld of durvalumab recorded in case report form. Short interruptions defined as the durvalumab infusion interruption during the administration recorded in CRF in a single visit were excluded from the analysis. Due to data issue, the reason for treatment withheld was not captured in the database.

The SAF included all enrolled participants who took at least 1 dose of durvalumab.

The overall duration of durvalumab treatment interruption was calculated as the sum of the duration of each treatment withheld/resumed. The duration of interruption included only treatment withheld. Short interruption which resumed during the same visit was not included in the calculation for duration of interruption.

The SAF included all enrolled participants who took at least 1 dose of durvalumab.

Pulmonary TEAEs were defined as any pulmonary AEs that occurred or worsened at any time after the start of administration of the first dose of durvalumab and through 30 days after the last dose of durvalumab.

The SAF included all enrolled participants who took at least 1 dose of durvalumab.

Pulmonary TEAEs were defined as any pulmonary AEs that occurred or worsened at any time after the start of administration of the first dose of durvalumab and through 30 days after the last dose of durvalumab. Duration of pulmonary TEAEs was calculated as end date of pulmonary TEAE minus onset date of pulmonary TEAE plus 1. For AEs that were missing an end date, the data cut-off date was used as the AE end date for calculation of AE duration.

The SAF included all enrolled participants who took at least 1 dose of durvalumab. Only those participants with pulmonary TEAEs excluding pneumonitis were included in this analysis.

Pneumonitis TEAEs were defined as any pneumonitis AEs that occurred or worsened at any time after the start of administration of the first dose of durvalumab and through 30 days after the last dose of durvalumab.

The SAF included all enrolled participants who took at least 1 dose of durvalumab. Only those participants with pneumonitis TEAEs were analyzed.

Pneumonitis TEAEs were defined as any pneumonitis AEs that occurred or worsened at any time after the start of administration of the first dose of durvalumab and through 30 days after the last dose of durvalumab.

The SAF included all enrolled participants who took at least 1 dose of durvalumab. Only those participants with pneumonitis TEAEs were analyzed.

Duration of development of Grade 3 to 5 pneumonitis AEs is defined as the period from Day 1 to earliest of each grade of pneumonitis AE (grade 3, grade 4, and grade 5). Severity (intensity of an event) was assessed using the NCI-CTCAE v5. AEs were assigned to a Grade from 1 through 5 as follows: Grade 1: Mild; Grade 2: Moderate; Grade 3: Severe or medically significant but not immediately life-threatening requiring hospitalization; Grade 4: Life-threatening consequences; Grade 5: Death due to any AE.

Data was not collected due to early termination of the trial.

The EORTC QLQ-C30 consisted of 30 questions and included functional scales (FS) (items 1-7 and items 20-27), symptom scales (items 8-19 and item 28) and global measure of health status (GHS) (items 29-30). The scale ranged from 1-4 for most outcome measures of systems, with 1 rated as "not at all" and 4 rated as "very much". Scores were averaged and transformed to 0 to 100, a high score for functional scales/GHS represented better functioning ability/QoL, whereas a high score for symptom scales represented stronger symptoms/worse QoL. Participants with pneumonitis TEAEs with causal relationship with durvalumab are presented. Time point 1: prior to occurrence of initial pneumonitis AE; Time point 2: at same time point as initial pneumonitis AE; Time point 3: when highest CTCAE grade of pneumonitis AE occurred. Baseline was defined as the date of informed consent for this parameter.

The SAF included all enrolled participants who took at least 1 dose of durvalumab. For each symptom scale, only those participants with data available were included in the analysis.

The EORTC QLQ-LC13 was a disease-specific 13-item questionnaire for lung cancer used in conjunction with the EORTC QLQ-C30. It comprised both multi-item and single-item measures of lung cancer associated symptoms (LCAS) (items 31-35 and items 40-42), treatment related side effects (TREF) (items 36-39) and pain medication (item 43). The scale ranged from 1-4 for most outcome measures of systems, 1 rated as "not at all" and 4 rated as "very much". Scores were averaged and transformed to 0 to 100, higher scores for LCAS and TREF: greater level of symptoms/worse QoL and higher scores for pain medication: better pain relief from medication. Participants with pneumonitis TEAEs with causal relationship with durvalumab are presented. Time point 1: prior to occurrence of initial pneumonitis AE; Time point 2: at same time point as initial pneumonitis AE; Time point 3: when highest CTCAE grade of pneumonitis AE occurred. Baseline was defined as the date of informed consent for this parameter.

The SAF included all enrolled participants who took at least 1 dose of durvalumab. For each symptom scale, only those participants with data available were included in the analysis.
