- 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. Further development of BIIB059 in CLE is warranted.Disclosure of Interests:Victoria Werth Grant/research support from: Biogen, Celgene, Gilead, Janssen, Viela, Consultant of: Biogen, Gilead, Janssen, Abbvie, GSK, Resolve, AstraZeneca, Amgen, Eli Lilly, EMD Serono, BMS, Viela, Kyowa Kirin, Richard Furie Grant/research support from: AstraZeneca, Biogen, Consultant of: AstraZeneca, Biogen, Juanita Romero-Diaz Consultant of: Biogen, Sandra Navarra Speakers bureau: Astellas, Novartis, Pfizer, Johnson & Johnson, Abbvie, Kenneth Kalunian Grant/research support from: Pfizer, Lupus Research Alliance, Sanford Consortium, Consultant of: Genentech, Nektar, BMS, Janssen, AstraZeneca, Biogen, Vielabio, Equillium, Eli Lilly, ILTOO, Abbvie, Amgen, Roche, Gilead, Ronald van Vollenhoven Grant/research support from: AbbVie, Arthrogen, Bristol-Myers Squibb, GlaxoSmithKline, Lilly, Pfizer, and UCB, Consultant of: AbbVie, AstraZeneca, Biotest, Bristol-Myers Squibb, Celgene, GSK, Janssen, Lilly, Medac, Merck, Novartis, Pfizer, Roche, and UCB, Filippa Nyberg Consultant of: Biogen, Benjamin Kaffenberger Grant/research support from: Amgen, Biogen, InflaRx, Veloce Biopharmaceuticals, Dermatology Foundation, Saira Sheikh: None declared, Goran Radunovic: None declared, XIAOBI HUANG Shareholder of: Biogen, Employee of: Biogen, HUA CARROLL Shareholder of: Biogen, Employee of: Biogen, Francois Gaudreault Shareholder of: Biogen, Employee of: Biogen, Adam Meyers Shareholder of: Biogen, Employee of: Biogen, Catherine Barbey Shareholder of: Biogen, Employee of: Biogen, Cristina Musselli Shareholder of: Biogen, Employee of: Biogen, NATHALIE FRANCHIMONT Shareholder of: Biogen, Employee of: Biogen
