Exclusion criteria 20

1. Participants with any of the following are excluded: (a) Sensitising EGFR mutations or ALK fusions (documented test result is mandatory for participants with non-squamous histology). For participants with squamous histology mutation/fusion, testing is mandatory only if participant is a never smoker or in the presence of a mixed histology. (b) Documented test result for any other known genomic alteration for which a targeted therapy is approved in first line per local standard of care (eg, ROS1, NTRK fusions, BRAF V600E mutation, etc).(c) Presence of small cell and neuroendocrine histology components.
2. Symptomatic brain metastases. Note: participants potentially are eligible with known asymptomatic CNS lesions that do not require local treatment according to principal investigator, or asymptomatic, adequately treated with stereotactic radiation therapy, craniotomy, gamma knife therapy, or whole brain radiotherapy, with no subsequent evidence of CNS progression. Participants must not require steroids or anticonvulsants for at least 4 weeks prior to start of study . A minimum of 2 weeks must have elapsed between the end of brain radiotherapy and enrolment. Participants must have recovered from the acute toxic effect of radiotherapy
3. Palliative radiotherapy with a limited field of radiation within 2 weeks or with a wide field of radiation or to more than 30% of the bone marrow within 4 weeks, prior to the first dose of study intervention. Note: Local treatment of isolated lesions for palliative intent is acceptable. Note: Participants must have recovered from all radiation-related toxicities and not require corticosteroids. A minimum of one week is permitted for palliative radiation (≤ 2 weeks of radiotherapy) to non-CNS disease.
4. Major surgical procedure (excluding placement of vascular access) or significant traumatic injury within 4 weeks of the first dose of study intervention or an anticipated need for major surgery during the study. Note: Local surgery of isolated lesions for palliative intent is acceptable.
5. Receipt of live attenuated vaccine within 30 days prior to the first dose of study intervention. Note: Participants should not receive live vaccine while receiving study intervention and up to 30 days after the last dose of study intervention. COVID-19 vaccination should not be given for 72 hours prior to administration of the first dose of study intervention.
6. Participation in another clinical study with a study intervention administered in the last 12 months or the combination/comparator agent (unless the safety profile is known prior to enrolment).
7. Judgement by the investigator that the individual should not participate in the study.
8. Concurrent enrolment into another interventional clinical trial, unless it is an observational (non-interventional) clinical study or during the follow-up period of an interventional study.
9. Involvement in the planning and/or conduct of the study (applies to both AstraZeneca staff and/or staff at the study site).
10. Judgement by the investigator that the participant should not participate in the study if the participant is unlikely to comply with study procedures, restrictions, and requirements.
11. As judged by the investigator, any severe or uncontrolled systemic diseases, including, but not limited to, uncontrolled hypertension, and active bleeding diseases, ongoing or active known infection; interstitial lung disease/pneumonitis (of any grade); unstable and/or symptomatic venous thromboembolism, serious chronic gastrointestinal conditions associated with diarrhoea active non-infectious skin disease, psychiatric illness/social situations, substance abuse, or significant conditions which, in the investigator’s opinion, makes it undesirable for the participant to participate in the study or that would jeopardise compliance with the protocol
12. Previous enrolment in the present study.
13. For females only - currently pregnant (confirmed with positive pregnancy test) or breast-feeding or planning to become pregnant.
14. Has had a prior stem cell, bone marrow, allogenic tissue, or solid organ transplant.
15. History of another primary malignancy except for malignancy treated with curative intent with no known active disease ≥ 2 years before the first dose of study intervention and of low potential risk for recurrence. Exceptions include adequately resected non-melanoma skin cancer, localised non-invasive primary disease under surveillance and curatively treated in situ disease.

Replacement therapy (eg, thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency) is not considered a form of systemic treatment and is allowed
18. Spinal cord compression.
19. Persistent toxicities (CTCAE ≥ Grade 2 caused by previous anti-cancer therapy excluding alopecia.

(ii)Non-cytotoxic drugs: 21 days or 5 half-lives (whichever is shorter). (iii)Biological products including immuno-oncology agents: 28 days. (b)Any investigational agents or study interventions from a previous clinical study: 28 days or 5 half-lives (whichever is shorter). (c)Immunosuppressive medication: except (i)Intranasal, inhaled, topical steroids, or local steroid injections (eg, intraarticular injection). (ii)Systemic corticosteroids at physiological doses not to exceed 10 mg/day of prednisone or equivalent. (iii)Steroids as premedication for hypersensitivity reactions

2. Part B: Dose expansion Safety and tolerability will be evaluated in terms of AEs/SAEs, imAEs, AEs leading to discontinuation, laboratory findings, ECGs, vital signs, and physical examinations.The estimates of interest are:Incidence of AEs/SAEs, imAEs, and AEs leading to discontinuation.Mean changes from baseline in laboratory parameters, vital signs, ECGs, and physical examination.
3. Part B: Dose expansion :Objective response is defined as BOR of confirmed CR or confirmed PR, as determined by the investigator at local site per RECIST1.1. The estimate of interest is • OR The analysis will include participants in the Response Evaluable Analysis Set. Participants will be analyzed according to their planned treatment and indication
