A Platform Study in Non-Small Cell Lung Cancer (NSCLC)

A Phase Ib/II Open-Label, Multicentre Platform Study Evaluating Novel Combinations in Participants With Advanced or Metastatic Non-Small Cell Lung Cancer

The purpose of this study is to assess the safety and efficacy of multiple study interventions including novel-novel combinations or novel agents in combination with standard therapy for the treatment of metastatic NSCLC.

This is a multicentre, open-label study to evaluate the safety and efficacy of various combinations of study interventions in participants with advanced or metastatic NSCLC (mNSCLC).

The study will include a sub-study (sub-study 2) focused on a specific treatment that may include 2 parts -

1. Part A consisting of one of more safety run-in cohorts to evaluate 2 or more dose levels to identify the recommended Phase 2 dose (RP2D) unless RP2D has been established then Part A will not be required; and
2. Part B consisting of one or more expansion cohorts.

The originally planned Sub-study 1 was withdrawn (cancelled) and will not be conducted.

Sub-study 2 will evaluate the safety, tolerability, and anti-tumour activity of rilvegostomig plus standard of care (SoC) platinum-based chemotherapy, with or without ramucirumab.

Inclusion Criteria:

• Participants with confirmed squamous or non-squamous NSCLC with a current Stage IV mNSCLC.
• Provision of acceptable archival tumour tissue (or fresh tumour tissue biopsy if archival tumour tissue is not available and if clinically feasible) is mandatory at screening.

• Adequate coagulation and urinalysis.
• Minimum body weight of 30 kg.

Exclusion Criteria:

• Participants with epidermal growth factor receptor mutations, anaplastic lymphoma receptor fusions or any other known genomic alteration for which targeted therapy is approved in the first line per local standard of care.
• Presence of small cell and neuroendocrine histology components.
• Any severe or uncontrolled systemic diseases, including uncontrolled hypertension, and active bleeding diseases, ongoing or active known infection; interstitial lung disease/pneumonitis (of any grade); unstable and/or symptomatic venous thromboembolism, serious chronic gastrointestinal conditions associated with diarrhoea, active non-infectious skin disease or substance abuse.
• Has had a prior stem cell, bone marrow, allogenic tissue, or solid organ transplant.
• Has an active autoimmune disease that has required systemic treatment in the past 5 years.
• History of clinically significant arrhythmia, cardiomyopathy of any aetiology or symptomatic congestive heart failure.
• 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 or presence of small cell and neuroendocrine histology components.
• Persistent toxicities (common terminology criteria for adverse events [CTCAE] ≥ Grade 2) caused by previous anti-cancer therapy, excluding alopecia.
• Spinal cord compression or symptomatic brain metastases.
• Treatment with any other anti-cancer agents or immunosuppressive medication.
• Palliative radiotherapy with a limited field of radiation within 2 weeks or with a wide field of radiation or to more than 30% of the bone marrow within 4 weeks, prior to the first dose of study intervention.

Exclusion Criteria for Sub Study 2:

• Known active hepatitis A.
• Acute hepatitis B infection (anti-hepatitis B core antibody [HBc] immunoglobulin M [IgM] positive) or chronic hepatitis B infection with HBV DNA ≥ 2000 IU/mL.
• Active hepatitis C infection (anti-HCV positive with HCV RNA detectable) or anti- HCV positive with HCV RNA undetectable for less than 12 weeks following treatment for HCV.
• Known human immunodeficiency virus (HIV) infection that is not well controlled.
• Evidence of Grade ≥ 1 central nervous system (CNS) haemorrhage.
• Uncontrolled arterial hypertension ≥ 150 mm Hg (systolic) and/or ≥ 100 mm Hg (diastolic).

• Has experienced any arterial thrombotic event, a Grade ≥ 3 bleeding event or has gross haemoptysis.
• Has significant bleeding disorders, serious or nonhealing wound, ulcer or clinically relevant congestive heart failure.
• Has a bowel obstruction, history or presence of inflammatory enteropathy or extensive intestinal resection.
• Has cirrhosis at a level of Child-Pugh B (or worse), or cirrhosis (any degree) and a history of hepatic encephalopathy or clinically meaningful ascites resulting from cirrhosis.
• Prior systemic therapy received for advanced or mNSCLC.
• Prior exposure to an anti-T-cell immunoreceptor with Ig and Immunoreceptor Tyrosine-based Inhibition Motif domains (TIGIT) therapy or immune-oncology agent such as anti-programmed cell death protein 1 (PD-1), anti-PD-L1, or anti-cytotoxic T-lymphocyte associated antigen 4 (CTLA-4), or any other anti-cancer therapy targeting immune-regulatory receptors or mechanisms.
• Chronic therapy with antiplatelet agents.
• Prior exposure to anti-vascular endothelial growth factor (VEGF) therapy.
• Medical contraindication to protocol-specified platinum doublet regimens or ramucirumab.
• Known allergy or hypersensitivity to rilvegostomig or any of the excipients of rilvegostomig, cisplatin, carboplatin, paclitaxel or nab-paclitaxel or pemetrexed or ramucirumab.
