About this trial
ARCH is a randomised, stratified, multicentre, phase III trial. Protocol treatment consists of cemiplimab, 350 mg i.v., every 3 weeks, for 4 cycles, followed by 700 mg i.v., every 6 weeks for 6 cycles or until relapse or unacceptable toxicities, whichever occurs first. The primary objective of the study is to determine the efficacy of adjuvant cemiplimab, as measured by disease-free survival, in patients without prior adjuvant platinum-based chemotherapy, compared to observation without adjuvant treatment. The primary objective will be assessed in patients with tumours with centrally confirmed PD-L1 expression of ≥1%.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Pathological stage II-IIIA (UICC/ AJCC staging 9th edition) NSCLC Brain imaging should have been performed to complete staging, either preoperatively or postoperatively. If brain imaging has not been performed, a contrast-enhanced CT or MRI of the brain must be performed at screening prior randomisation.
Complete resection with negative surgical margins (R0).
Lobectomy, sleeve lobectomy, bilobectomy, or pneumectomy.
Segmentectomy for tumours ≤2 cm is permitted in patients with poor pulmonary reserve or another major comorbidity that contraindicates lobectomy.
Disqualifiers
EGFR-mutant or ALK-rearranged NSCLC.
Any small cell component
Prior neoadjuvant and/or adjuvant systemic treatment for NSCLC.
Treatment with an approved systemic therapy is completed >4 weeks before randomisation or

Trial outcomes
Primary outcomes
Disease-free survival (DFS)
Disease free survival (in patients with tumours with centrally confirmed PD-L1 expression of ≥1%).
Secondary outcomes
Overall survival (OS)
OS is defined as the time from the date of randomisation until death from any cause. Censoring (for patients who are not reported as having died) will occur at the date last known to be alive. Patients without post-randomisation information will be censored at the date of randomisation (plus 1 day).
Incidence, nature and severity of adverse events according to CTCAE v5.
All safety parameters will be summarised in tables to evaluate the toxicity/safety profile of the protocol treatment.
