      Background

      Immune checkpoint inhibitor (ICI)-containing regimens have significantly improved survival outcomes in first- and second-line non-small cell lung cancer (NSCLC). However, few patients have-durable responses to anti-programmed cell death‑1/programmed cell death-ligand 1 (anti-PD-[L]1)-containing therapy (primary resistance) or other patients progress during anti-PD-(L)1-containing therapy (acquired resistance). HUDSON addresses the urgent need to identify new treatments and understand ICI resistance for patients who progressed after receiving anti-PD-(L)1-containing therapy.

      Method

      HUDSON is a multi-centre, international, multi-arm, platform study (NCT03334617), which will 1) evaluate therapies to reverse ICI resistance and 2) define mechanisms of ICI resistance in patients with NSCLC who have progressed following standard-of-care platinum- and ICI-based therapies. HUDSON consists of biomarker matched and non-matched groups (Figure). Allocation is guided by tumour molecular profile, using a pre-specified algorithm. Pre-existing local next generation sequence (NGS) data enables rapid patient allocation to biomarker-matched groups. Central molecular profiling comprises NGS and immunohistochemistry data. New groups will be added as new translational hypotheses emerge. Translational research will employ serial peripheral blood samples (including ctDNA) and tumour biopsies.

      Result

      Enrolment is ongoing; as of 01 April 2019, patients have been dosed in each of the drug combinations currently open for recruitment. Analyses of tissue and blood samples collected for exploratory research are ongoing, including genomic, transcriptomic and chemistry biomarkers such as tumour mutation burden, human leukocyte antigen status, T-cell receptor repertoire, and peripheral immune activation signatures.

      Conclusion

      Specific differences between patients on individual HUDSON arms that inform anti-PD(L)1 resistance mechanisms, plus learnings from the implementation of this innovative and complex platform study will be presented.
