      Background

      Immune checkpoint inhibitor (ICI)-containing regimens have significantly improved survival outcomes in first- and second-line NSCLC. However, the majority of patients do not respond or have non-durable responses to anti-programmed cell death-1/programmed cell death-ligand 1 (anti-PD-1/PD-L1) containing therapy (primary resistance) or progress during anti-PD-1/PD-L1 containing therapy (acquired resistance). HUDSON addresses the urgent need to identify treatments and understand ICI resistance for this emerging ICI-resistant population.

      HUDSON is a multi-centre, international multi-arm umbrella study that will 1) evaluate therapies to reverse ICI resistance and 2) define mechanisms of ICI resistance in NSCLC patients who have progressed following standard-of-care platinum and ICI-based therapies. HUDSON is a platform study that consists of two groups; a biomarker matched and a biomarker non-matched group. Within the biomarker matched group, different cohorts will test 1) homologous recombination repair (HRR) defects and 2) LKB1 aberration for response to durvalumab and olaparib (PARP inhibitor), 3) ATM deficiency for response to durvalumab and AZD6738 (ATR inhibitor) and 4) RICTOR amplification for response to durvalumab and vistusertib (mTORC1/2 inhibitor). In the biomarker non-matched group, cohorts will test durvalumab in combination with either i) olaparib, ii) AZD9150 (STAT3 inhibitor) or iii) AZD6738, in patients with primary and acquired resistance to a prior ICI. Allocation to a cohort is informed by the tumour molecular profile according to a pre-specified assignment algorithm. New cohorts will be added as new translational hypotheses are established. Translational research will be performed on serial peripheral blood samples (including ctDNA) and tumour biopsies. HUDSON enrols ICI-resistant patients in a signal searching manner. Biomarker matched and non-matched groups will be opened simultaneously, and all eligible patients can be allocated a treatment option irrespective of their tumour profile. Enrolment is ongoing, clinical trial information: NCT03334617.
