A DLT was defined as \>= Grade 3 toxicity or adverse events (AE) occurred during DLT evaluation period which included any Grade 4 immune-mediated (immune nature) AE, anemia, thrombocytopenia (present \> 4 days), or neutropenia (present \> 4 days); \>= Grade 3 colitis or pneumonitis or interstitial lung disease (ILD); \>= Grade 3 nausea, vomiting, or diarrhea (not resolved to \<= Grade 2 in 3 days); Grade 2 pneumonitis or ILD (not resolved to \<= Grade 1 in 3 days); Grade 3 thrombocytopenia with bleeding, any grade febrile neutropenia; convulsions, seizures, or stroke; protocol defined elevations of isolated liver transaminase, isolated total bilirubin (TBL), or Hy's Law; confirmed QT interval corrected for heart rate by Fridericia's formula prolongation (\>= 501 msec) on triplicate electrocardiograms within a short period of time; or any other toxicity greater than that at baseline, was clinically significant and/or unacceptable, and was judged to be a DLT by the Dose Escalation Committee.

An AE is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. A serious adverse event (SAE) is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. The TEAEs are defined as events present at baseline that worsened in intensity after administration of study drug or events absent at baseline that emerged after administration of study drug.

Participants with abnormal laboratory parameters reported as TEAEs are reported. Laboratory analysis included hematology, clinical chemistry, thyroid function tests, and urinalysis.

Participants with abnormal vital signs (heart rate, blood pressure, temperature, and respiratory rate) and physical examination reported as TEAEs are reported.

Notable QTc intervals included single beat changes from baseline (Day 1) values (\> 30, \> 60, and \> 90 milliseconds). Participants who had notable QTc interval are reported.

The OR is defined as confirmed complete response (CR) or confirmed partial response (PR) based on RECIST v1.1 guidelines. The CR is defined as disappearance of all target and non-target lesions, no new lesions, and normalization of tumor marker level. The PR is defined as \>= 30% decrease in the sum of the diameters of target lesions compared to baseline, and non-progressive disease and not evaluable or no non-target lesion. A confirmed CR or PR is defined as 2 CRs or 2 PRs that were separated by at least 4 weeks with no evidence of progression in-between.

The DoR is defined as duration from the first documentation of OR (confirmed CR or PR) to the first documented disease progression based on RECIST v1.1 guidelines or death due to any cause, whichever occurs first. A CR is defined as disappearance of all target and non-target lesions, no new lesions, and normalization of tumor marker level. A PR is defined as \>= 30% decrease in the sum of the diameters of target lesions compared to baseline, and non-progressive disease and not evaluable or no non-target lesion. A confirmed CR or PR is defined as 2 CRs or 2 PRs that were separated by at least 4 weeks with no evidence of progression in-between. The progressive disease is defined at least a 20% increase in sum of the longest diameter of target lesions, taking as reference the smallest sum longest diameter recorded since treatment started, the appearance of one or more new lesions, or unequivocal progression of existing non-target lesions. The DoR was analyzed using Kaplan-Meier method.

The DC is defined as percentage of participants with CR, PR, or stable disease (SD, which was maintained by \>= 8 week) based on RECIST v1.1 guidelines. A CR is defined as disappearance of all target and non-target lesions, no new lesions, and normalization of tumor marker level. A PR is defined as \>= 30% decrease in the sum of the diameters of target lesions compared to baseline, and non-progressive disease and not evaluable or no non-target lesion. The SD is defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for disease progression, taking as reference the smallest sum longest diameter since the study treatment started, and non-progressive disease and not evaluable or no non-target lesion.

The PFS is defined as the time from the start of study treatment until the documentation of disease progression based on RECIST version 1.1 or death due to any cause, whichever occurs first, regardless of whether the participant received subsequent anticancer treatment prior to progression. The progressive disease is defined at least a 20% increase in the sum of the longest diameter of target lesions, taking as reference the smallest sum longest diameter recorded since the treatment started, the appearance of one or more new lesions, or unequivocal progression of existing non-target lesions. Participants who were alive and progression-free at the time of data cut-off for analysis had PFS censored at the last tumor assessment date. The PFS was estimated using Kaplan-Meier method.

The OS is defined as the time from the start of study treatment until death due to any cause. Participants who are alive at the time of data cut-off had OS censored at the last known to be alive date. The OS was estimated using Kaplan-Meier method.

The T790M status was determined by plasma testing in a central laboratory at Baseline (Days -28 to -1). The OR is defined as confirmed CR or confirmed PR based on RECIST v1.1 guidelines. The CR is defined as disappearance of all target and non-target lesions, no new lesions, and normalization of tumor marker level. The PR is defined as \>= 30% decrease in the sum of the diameters of target lesions compared to baseline, and non-progressive disease and not evaluable or no non-target lesion. A confirmed CR or PR is defined as 2 CRs or 2 PRs that were separated by at least 4 weeks with no evidence of progression in-between. Cell-free circulating tumor deoxyribonucleic acid (ctDNA) from liquid biopsy was used as a surrogate marker for T790M status in tumor tissue.

The T790M status was determined by plasma testing in a central laboratory at Baseline (Days -28 to -1). The DC is defined as percentage of participants with CR, PR, or SD (maintained by \>= 8 week) based on RECIST v1.1 guidelines. A CR is defined as disappearance of all target and non-target lesions, no new lesions, and normalization of tumor marker level. A PR is defined as \>= 30% decrease in the sum of longest diameters of target lesions compared to baseline, and non-progressive disease and not evaluable or no non-target lesion.

As-treated population included all participants who received any study drug and were analyzed according to the treatment they actually received.

Arm B (Oleclumab + AZD4635 groups) did not proceed to the dose expansion phase due to lack of response to treatment and a change in the formulation of AZD4635. The OR and DC by T790M status for 'Oleclumab + AZD4635' groups were not conducted due to the small sample size.
