Trial overview
Official title: A Phase II, Randomized, Open-label Platform Trial Utilizing a Master Protocol to Study Novel Regimens Versus Standard of Care Treatment in NSCLC Participants
Trial description: This study will compare the clinical activity of novel regimens (in combination or as single agents) to SoC in participants with relapsed/refractory advanced NSCLC. The study will be conducted in two parts. Part 1 is an open-label, optional, non-randomized part based on safety and pharmacokinetics/pharmacodynamics (PK/PD) evaluation intended to generate additional data to qualify novel regimens for the randomized study. Part 2 is a randomized, Phase II open-label part comparing the efficacy and safety of these novel regimens with SoC. Drug name mentioned as GSK4428859A (belrestotug) and EOS884448 are interchangeable for the same compound and will be referred to as GSK4428859A/EOS884448/belrestotug.

Inclusion and exclusion criteria
Inclusion criteria:
- Participants capable of giving signed informed consent/assent.
- Male or female, aged 18 years or older at the time consent is obtained. Participants in Korea must be age 19 years or older at the time consent is obtained.
- Participants with histologically or cytologically confirmed diagnosis of NSCLC (squamous or non-squamous) and a) Documented disease progression based on radiographic imaging, during or after a maximum of 2 lines of systemic treatment for locally/regionally advanced recurrent, Stage IIIb/Stage IIIc/Stage IV or metastatic disease. Two components of treatment must have been received in the same line or as separate lines of therapy: i) No more than or less than 1 line of platinum-containing chemotherapy regimen, and ii) No more than or less than 1 line of Programmed cell death ligand 1 (PD[L]1) monoclonal antibody (mAb) containing regimen. b) Participants with known BRAF molecular alterations must have had disease progression after receiving the locally available SoC treatment for the molecular alteration. c) Participants who received prior anti-PD(L)1 therapy must fulfill the following requirements: i) Have achieved a CR, PR or SD and subsequently had disease progression (per RECIST 1.1 criteria) either on or after completing PD(L)1 therapy ii) Have not progressed or recurred within the first 12 weeks of PD(L)1 therapy, either clinically or per RECIST 1.1 criteria
