This study is for patients with advanced/metastatic non-small cells lung cancer (NSCLC) who have not received any treatment through the vein for the advanced disease.

This is a multicenter open-label phase 2 trial that aim to assess the safety, tolerability, and efficacy of EIK1001 in combination with standard of care in participants with both confirmed stage 4 squamous and non-squamous NSCLC who have not received prior systemic therapy for the advanced disease. The study includes dose finding and evaluates adverse events and efficacy.

Inclusion Criteria:

1. be ≥ 18 years of age on the day of signing of informed consent.
2. confirmed Stage 4 NSCLC (squamous or non-squamous) and be considered for standard of care.
3. have confirmation that mutation-directed therapy is not indicated (documentation of absence of tumor activating mutations/fusions that are approved for first line therapy).
4. have at least 1 lesion with measurable disease at Baseline according to RECIST 1.1 as determined by the local site Investigator/radiology assessment.
5. have not received prior systemic treatment for advanced/metastatic NSCLC.
6. have an ECOG Performance Status of 0 to 1.
7. have adequate organ function.

Exclusion Criteria:

1. does not have predominantly squamous cell or non-squamous cell histology NSCLC. Mixed tumors will be categorized by the predominant cell type; if small cell elements are present, the participant is ineligible.
2. is currently participating in or has participated in a study of an investigational agent and received investigational therapy within 4 weeks or 5 half-lives (whichever is shorter) of administration of EIK1001.
3. prior to the first dose of EIK1001, has received prior systemic therapy for metastatic disease, or had major surgery (< 3 weeks prior to the first dose).
4. has completed palliative radiotherapy within 7 days of the first dose of study drug administration.
5. has a known history of prior malignancy, except if the participant has undergone potentially curative therapy with no evidence of that disease recurrence for 5 years.
6. has an active infection requiring therapy.
