Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Pharmacokinetic, Efficacy, Safety, Pharmacodynamic

To demonstrate the efficacy of rilvegostomig plus chemotherapy relative to pembrolizumab plus chemotherapy by assessment of OS and PFS

Secondary objectives 6

1. To characterize the efficacy of rilvegostomig plus chemotherapy relative to pembrolizumab plus chemotherapy by assessment of OS, PFS, and DoR
2. To compare the efficacy of rilvegostomig plus chemotherapy relative to pembrolizumab plus chemotherapy by assessment of PFS2
3. To characterize and compare the efficacy of rilvegostomig plus chemotherapy relative to pembrolizumab plus chemotherapy by assessment of ORR
4. To assess the PK of rilvegostomig, patient-reported physical functioning, patient-reported GHS/QoL, patient-reported lung cancer symptoms of NSCLC, and the the safety and tolerability of rilvegostomig plus chemotherapy compared to pembrolizumab plus chemotherapy
5. To investigate the immunogenicity of rilvegostomig
6. To assess the safety and tolerability of rilvegostomig plus chemotherapy compared to pembrolizumab plus chemotherapy

Plan to share IPD

Yes

IPD plan description

Qualified researchers can request access to anonymized individual patient-level data from AstraZeneca group of companies sponsored clinical trials via the request portal Vivli.org. All requests will be evaluated as per the AZ disclosure commitment: https://astrazenecagrouptrials.pharmacm.com/ST/Submission/Disclosure. Yes, indicates that AZ are accepting requests for IPD, but this does not mean all requests will be shared. AstraZeneca will meet or exceed data availability as per the commitments made to the EFPIA PhRMA Data Sharing Principles. When a request has been approved AstraZeneca will provide access to the anonymized individual patient-level data via secure research environment https://vivli.org/. Signed Data Usage Agreement (non-negotiable contract for data accessors) must be in place before accessing requested information.

Eligibility criteria

Principal inclusion / exclusion criteria as submitted by sponsor

Inclusion criteria 6

1. Histologically or cytologically documented squamous NSCLC.
2. Stage IV mNSCLC (based on the American Joint Committee on Cancer Edition 8) not amenable to curative treatment.
3. Absence of documented tumor genomic mutation results from tests conducted as part of standard local practice in any actionable driver oncogenes for which there are locally approved targeted 1L therapies.
4. Provision of acceptable tumor sample to confirm tumor PD-L1 expression TC ≥ 1%
5. At least one lesion not previously irradiated that qualifies as a RECIST 1.1 TL at baseline and can be accurately measured at baseline as ≥ 10 mm in the longest diameter (except lymph nodes, which must have short axis ≥ 15 mm) with CT or MRI and is suitable for accurate repeated measurements.
6. Adequate organ and bone marrow function

Exclusion criteria 9

1. Presence of small cell and neuroendocrine histology components.
2. Brain metastases unless asymptomatic, stable, and not requiring steroids or anticonvulsants for at least 7 days prior to randomization. A minimum of 2 weeks must have elapsed between the end of local therapy (brain radiotherapy or surgery) and randomization. Participants must have recovered from the acute toxic effect of radiotherapy (eg, dizziness and signs of increased intracranial pressure) or surgery prior to randomization.
3. Any prior systemic therapy received for advanced or mNSCLC.
4. Prior treatment with an anti-PD-1 or anti-PD-L1 agent.
5. Any prior exposure to an anti-TIGIT therapy or any other anticancer therapy targeting immune-regulatory receptors or mechanisms.
6. History of another primary malignancy except for malignancy treated with curative intent with no known active disease ≥ 2 years before the first dose of study intervention and of low potential risk for recurrence.
7. Active or prior documented autoimmune or inflammatory disorders requiring chronic treatment with steroids or other immunosuppressive treatment.
8. Active primary immunodeficiency/active infectious disease(s)
9. Active tuberculosis infection

6. Concentration of rilvegostomig in serum.
7. Presence of antidrug antibody (ADAs), titer and neutralizing antibodies for rilvegostomig.
8. Proportion of participants with maintained or improved physical functioning.
9. Time to deterioration (TTD) of global health status (GHS)/quality of life (QoL) and in pulmonary symptoms.
10. Adverse events (AEs) (graded by CTCAE version 5.0), clinical laboratory assessments, vital signs, and Eastern Cooperative Oncology Group (ECOG) performance status.
