Global Clinical Landscape & Future Outlook

The race for RSK2/RSK3 therapeutics is intensifying, with major players shifting focus from traditional broad kinase inhibitors to highly selective covalent inhibitors and allosteric modulators. As first-generation therapies reach the clinic, the next wave of R&D is targeting bypass resistance in MAPK-driven tumors, particularly in triple-negative breast cancer (TNBC) and non-small cell lung cancer (NSCLC).

Competitive Modality & Indication Snapshot

Modality Representative Players Key Indications Critical Assay Need (Why TarMart?)
