A Phase 3 interventional study of Rilvegostomig and Pembrolizumab in Non-squamous Non-small Cell Lung Cancer, sponsored by AstraZeneca. Recruiting at 301 sites in 25 countries. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-10-28.
Sponsored by AstraZeneca · Phase 3, Interventional, and Treatment
The purpose of ARTEMIDE-Lung03 is to evaluate the efficacy and safety of rilvegostomig compared to pembrolizumab, both in combination with platinum-based doublet chemotherapy, as a first-line treatment of patients with locally advanced or metastatic non-squamous NSCLC whose tumors express PD-L1.
This is a Phase III, two-arm, randomized, double-blind, global, multicenter study assessing the efficacy and safety of rilvegostomig compared to pembrolizumab, both in combination with platinum-based doublet chemotherapy, as a 1L treatment for patients with locally advanced or metastatic non-squamous NSCLC whose tumors express PD-L1 (TC ≥ 1%).

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).
Your pathology report is the document that shows this.
PD-1, PD-L1 and CTLA-4 are proteins that act as brakes on the immune system. Checkpoint inhibitors, such as pembrolizumab or nivolumab, block them so the immune system can attack a cancer.
PD-L1 can also be measured in a tumour sample. Some scores count stained tumour cells only (TPS); others also count certain immune cells (CPS). The study names the score and the minimum it uses.
The standard rules for measuring tumours on CT or MRI scans, to tell whether a cancer is shrinking, stable or growing during treatment.
“Measurable disease per RECIST 1.1” usually means at least one tumour 10 mm or more at its longest on a CT scan, or a lymph node 15 mm or more across its short axis.
Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).
Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumour. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.
Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Started Nov 2024 (actual). Primary completion is estimated for Nov 2030, 71 months after the start.
Of 314 industry-sponsored phase 3 interventional studies under Carcinoma, Non-Small-Cell Lung, half reached primary completion within 39 months of starting (the median), counting those still running; a quarter within 27 and three quarters within 57. This study's planned 71 months is above that.
Counting every sponsor, half of 423 studies reached it within 45 months; a quarter within 30 and three quarters within 69.
