    • We have recently completed the largest GWAS on lung cancer including 29,266 cases and 56,450 controls of European descent. The goal of our study has been to integrate the complete GWAS results with a large‐scale expression quantitative trait loci (eQTL) mapping study in human lung tissues (n = 1,038) to identify candidate causal genes for lung cancer. We performed transcriptome‐wide association study (TWAS) for lung cancer overall, by histology (adenocarcinoma, squamous cell carcinoma and small cell lung cancer) and smoking subgroups (never‐ and ever‐smokers). We performed replication analysis using lung data from the Genotype‐Tissue Expression (GTEx) project. DNA damage assays were performed in human lung fibroblasts for selected TWAS genes. As expected, the main TWAS signal for all histological subtypes and ever‐smokers was on chromosome 15q25. The gene most strongly associated with lung cancer at this locus using the TWAS approach was IREB2 (pTWAS = 1.09E−99), where lower predicted expression increased lung cancer risk. A new lung adenocarcinoma susceptibility locus was revealed on 9p13.3 and associated with higher predicted expression of AQP3 (pTWAS = 3.72E−6). Among the 45 previously described lung cancer GWAS loci, we mapped candidate target gene for 17 of them. The association AQP3‐adenocarcinoma on 9p13.3 was replicated using GTEx (pTWAS = 6.55E−5). Consistent with the effect of risk alleles on gene expression levels, IREB2 knockdown and AQP3 overproduction promote endogenous DNA damage. These findings indicate genes whose expression in lung tissue directly influences lung cancer risk.

  • BIIB059, A HUMANIZED MONOCLONAL ANTIBODY TARGETING BDCA2 ON PLASMACYTOID DENDRITIC CELLS (PDC), SHOWS DOSE-RELATED EFFICACY IN THE PHASE 2 LILAC STUDY IN PATIENTS (PTS) WITH ACTIVE CUTANEOUS LUPUS ERYTHEMATOSUS (CLE)

    • CLE represents an unmet medical need with no approved therapy. BIIB059, a humanized monoclonal antibody, binds to BDCA2 and inhibits pro-inflammatory mediators production, including type I interferons. BIIB059 was evaluated in Phase 1 studiesNCT02106897andNCT03224793. LILAC is a 2-part Phase 2 study: Part A enrolled SLE pts; Part B enrolled pts with active CLE (NCT02847598).Objectives:Evaluate efficacy and safety of BIIB059 in pts enrolled in Part B at Week 16, end of treatment (EOT) period.Methods:Pts with active CLE, SCLE and/or CCLE and adjudicated Cutaneous Lupus Disease Area and Severity Index – Activity (CLASI-A) ≥8 were enrolled and randomized to receive either BIIB059 (50, 150 or 450 mg) or placebo (PBO) s.c. Q4W. Primary endpoint was dose response defined by % change in CLASI-A score from baseline (BL) to Week 16. Secondary endpoints included CLASI-50 response rate and ≥ 7-point reduction in CLASI-A score from baseline to EOT. Adverse events and serious adverse events were recorded throughout the study.Results:132 pts with active CLE were randomized. The study met its primary endpoint, demonstrating a dose response (p= 0.0005) and a statistically significant difference in % change from BL in CLASI-A score in BIIB059-treated pts vs PBO. Table 1 and Table 2 summarize efficacy and safety results, respectively.Table 1.Efficacy EndpointsBIIB059PBO50 mg150 mg450 mgLS Mean (SE)LS Mean (SE)LSMD*from PBO (95% CI)P val.LS Mean(SE)LSMD*from PBO (95% CI)P val.LS Mean(SE)LSMD*from PBO (95% CI)P val.Primary EndpointCLASI-A % change from BL-14.5 (6.4)-40.8 (7.5)-26.3 (-45.7; -7.0)0.008-47.9 (7.4)-33.5 (-52.7; -14.3)0.001-43.5 (5.5)-28.0 (-44.5; -11.5)0.001Secondary Endpointsn(%)n(%)LSMD*from PBO (95% CI)P val.n(%)LSMD*from PBO (95% CI)P val.n(%)LSMD*from PBO (95% CI)P val.Prop. of participants achieving CLASI 507/32 (21.9%)10/26 (38.5%)15.8% (-7; 39)0.13311/25 (44.0%)21 (-2.8; 45)0.05920/43 (46.5%)23 (3; 44)0.024Prop. of participants achieving a ≥7-point CLASI-A reduction from BL7/32 (21.9%)9/26 (34.6%)12.3 (-11.3; 35.8)0.22812/25 (48.0%)22.2 (-2.0; 46.3)0.05518/43 (41.8%)16.8 (-6.7; 40.4)0.048*LSMD=LS Mean DifferencePBOBIIB059OVERALLN=3350 mgN=26150 mgN=25450 mgN=48PooledN=99N=132Any Event, n(%)18 (54.5)17 (65.4)12 (48)33 (68.8)62 (62.6)80 (60.6)SeverityMild11 (33.3)11 (42.3)8 (32.0)19 (39.6)38 (38.4)49 (37.1)Moderate4 (12.1)6 (23.1)3 (12.0)12 (25.0)21 (21.2)25 (18.9)Severe3 (9.1)01 (4.0)2 (4.2)3 (3.0)6 (4.5)Related events6 (18.2)9 (34.6)4 (16.0)16 (33.3)29 (29.3)35 (26.5)Serious events2 (6.1)03 (12.0)2 (4.2)5 (5.1)7 (5.3)Related serious events1 (3.0)01 (4.0)1 (2.1)2 (2.0)3 (2.3)Events leading to drug withdrawal01 (3.8)1 (4.0)1 (2.1)3 (3.0)3 (2.3)Events leading to study withdrawal0001 (2.1)1 (1.0)1 (0.8)Fatal events000000Conclusion:BIIB059 administration to pts with active CLE resulted in statistically significant dose-related improvement in disease activity vs PBO with no untoward safety signals.
