* The effects of the study drug on the developing human fetus are unknown. For this reason female of child-bearing potential (FCBP) must have a negative serum or urine pregnancy test prior to starting therapy
* FCBP and men must agree to use adequate contraception (at least one highly effective method and one additional method of birth control at the same time or complete abstinence) prior to study entry, for the duration of study participation and for at least 4 months following study drug discontinuation.

A female of childbearing potential (FCBP) is a sexually mature woman who: 1) has not undergone a hysterectomy or bilateral oophorectomy; or 2) has not been naturally postmenopausal for at least 12 consecutive months (if age \> 55 years); if the female subject is \< 55 years and she has been naturally postmenopausal for \> 1 year her reproductive status has to be verified by additional lab tests (\< 20 estradiol OR estradiol \< 40 with follicle stimulating hormone \[FSH\] \> 40 in women not on estrogen replacement therapy)
* Patient is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow up

Exclusion Criteria:

* Participation in another clinical study with an investigational product during the last 4 weeks
* ECOG PS 3 or higher
* Prior systemic therapy for the treatment of advanced or metastatic NSCLC
* Concurrent enrollment in another clinical study, unless it is an observational (non-interventional) clinical study or during the follow-up period of an interventional study
* Completed palliative radiotherapy within 7 days of the first dose of trial treatment
* Has a known sensitivity to any component of carboplatin, pemetrexed, paclitaxel, or durvalumab

* Any unresolved toxicity National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) grade \>= 2 from previous anticancer therapy with the exception of vitiligo, and the laboratory values defined in the inclusion criteria
* Patients with grade \>= 2 neuropathy will be evaluated on a case-by-case basis after consultation with the study physician
* Patients with irreversible toxicity not reasonably expected to be exacerbated by treatment with durvalumab may be included only after consultation with the study physician
* Any concurrent chemotherapy, investigational product (IP), biologic, or hormonal therapy for cancer treatment. Concurrent use of hormonal therapy for non-cancer-related conditions (e.g., hormone replacement therapy) is acceptable

The following are exceptions to this criterion:

  * Patients with vitiligo
  * Patients with hypothyroidism (e.g., following Hashimoto syndrome) stable on hormone replacement
  * Any chronic skin condition that does not require systemic therapy

Patients with a past or resolved HBV infection (defined as the presence of hepatitis B core antibody \[anti-HBc\] and absence of HBsAg) are eligible. Patients positive for 20. Active infection including tuberculosis (clinical evaluation that includes clinical history, physical examination and radiographic findings, and TB testing in line with local practice), hepatitis B (known positive HBV surface antigen (HBsAg) result), hepatitis C, or human immunodeficiency virus (positive HIV 1/2 antibodies).
