Inclusion criteria

Inclusion criteria: 1. Has pathologically (histologically or cytologically) confirmed diagnosis of NSCLC. 2. Has Stage IIIA, IIIB, or IIIC NSCLC by American Joint Committee on Cancer Version 8. 3. Is unable to undergo surgery with curative intent for Stage III NSCLC as documented by a multidisciplinary tumor board or by the treating physician in consultation with a thoracic surgeon. 4.

Participants for whom DLCO measurements are not available will be deemed to have adequate oxygen transfer if pulse oximetry (O2 saturation) is determined to be =90% on room air. 11. Has adequate organ function; all screening laboratory tests should be performed within 10 days prior to initiation of study intervention. 12. Participants are at least 18 years of age on the day of providing informed consent. 13.Male participants are eligible to participate if they agree to the following during the intervention period and for at least the time needed to eliminate each study intervention after the last dose of study intervention. The length of time required to continue contraception for each study intervention is as follows: -Olaparib and platinum doublet: 90 days Refrain from donating sperm PLUS either: -Be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis) and agree to remain abstinent OR -Must agree to use contraception as detailed below: Agree to use a male condom plus partner use of an additional contraceptive method when having penile-vaginal intercourse with a WOCBP who is not currently pregnant. 14. A female participant is eligible to participate if she is not pregnant or breastfeeding, and at least one of the following conditions applies: -is not a WOCBP OR •Is a WOCBP and: •Uses a contraceptive method that is highly effective (with a failure rate of <1% per year), with low user dependency, or be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long-term and persistent basis), during the intervention period and for at least the time needed to eliminate each study intervention after the last dose of study intervention and agrees not to donate eggs (ova, oocytes) to others or freeze/store for her own use for the purpose of reproduction during this period. The length of time required to continue contraception for each study intervention is as follows: •Pemb

Is currently receiving either strong or moderate inducers of CYP3A4 that cannot be discontinued for the duration of the study. The required washout period prior to starting olaparib is 5 weeks for pentobarbital and 3 weeks for other agents. 13.

The required washout period prior to starting olaparib is 2 weeks. 14. Pemetrexed-specific: Is unable to interrupt aspirin or other NSAIDs, other than an aspirin dose =1.3 grams per day, for at least 2 days (5 days for long-acting agents [for example, piroxicam]) before, during, and for at least 2 days after administration of pemetrexed. 15. Pemetrexed-specific: Is unable/unwilling to take folic acid, vitamin B12, and dexamethasone. 16.Has received an investigational agent or has used an investigational device within 4 weeks prior to study intervention administration. 17.

Has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior the first dose of study medication. 19. Has a known additional malignancy that is progressing or has required active treatment within the past 5 years. 20. Has severe hypersensitivity (= Grade 3) to study intervention and/or any of its excipients 21. Has an active autoimmune disease that has required systemic treatment in past 2 years (ie, with use of disease modifying agents, corticosteroids or immunosuppressive drugs).

Has a history of (noninfectious) pneumonitis/interstitial lung disease that required steroids or has current pneumonitis/interstitial lung disease.
