1. Market Overview

1.1 Global Oncology Market Context

The global oncology drug market was valued at approximately $175 billion in 2022 and is projected to expand at a CAGR of 8.4% from 2023 to 2030. Immune checkpoint inhibitors (ICIs), including PD-1/PD-L1 inhibitors, dominate this landscape, representing roughly 50% of total oncology therapeutic sales.

1.2 GOMEKLI’s Therapeutic Niche

GOMEKLI targets advanced NSCLC with high PD-L1 expression, representing a segment worth approximately $12 billion globally in 2022. Existing therapies like Pembrolizumab and Nivolumab capture the majority share but face pricing pressures and competitive innovation.
