Objective The objective of this study was to review the links between ethnicity, serology and clinical expression in systemic lupus erythematosus (SLE) in a single cohort that was followed over a 36-year period. Patients and methods Patients with SLE treated at the University College London Hospitals (UCLHs) between January 1978 and December 2013 formed the cohort. We assessed the demographic, clinical and serological data. Standard methods were used for laboratory testing. The Student t test and Mann–Whitney U test were used for the continuous variables; the Fisher’s exact test was used for the categorical variables. Results We studied 624 SLE patients: There were 571 women (91.5%), with a mean age at diagnosis of 29.0 ± 6.5 years; and 53 men (8.5%), with a mean age at diagnosis of 29.4 ± 15.3 years. Ethnically, 369 of the patients were European, 100 were Afro-Caribbean, 77 were East Asian, 56 were South Asian and 21 were of mixed ethnicity. The East Asian patients developed the disease at a younger age than the other ethnic groups ( p < 0.0001). The Afro-Caribbean patients were less frequently associated with the presence of rash and photosensitivity, and the non-European patients were more likely to have alopecia and renal involvement. The South Asian patients were significantly associated with musculoskeletal and neurological involvement, serositis, Sicca syndrome and hematological features. The Afro-Caribbean patients had the highest prevalence of anti-Smith, anti-RNP, anti-Ro and anti-La antibodies. Anti-IgG anticardiolipin (aCL) antibodies were significantly associated with the non-East Asian groups; and hypocomplementemia was common in the East Asians. Rash, alopecia, mouth ulcers, serositis, neurological, joint and renal involvement were significantly associated with the presence of anti-Smith and anti-RNP antibodies in the Afro-Caribbean group. We also observed an association of joint involvement and the presence of anti-Ro and anti-La antibodies in this group. Conclusions The East Asian patients developed their SLE disease at a younger age than the other ethnic groups. Cutaneous involvement was more frequent in those who were not Afro-Caribbean. Serositis, joint and neurological involvement were more frequently diagnosed in the South Asian patients. Anti-ENA antibodies were frequently associated with the Afro-Caribbean patients.

Abstract While it is well known that Glioblastoma (GBM) shows profound inter- and intra-tumoral heterogeneity, disparities in molecular features across ancestry groups have been largely overlooked. We collected a large cohort of GBM samples from East Asian patients (EAS-GBM) and performed genomic and transcriptomic analyses of these samples (EAS-GBM, n=443). Further characterization and comparative analysis of the EAS-GBM with the predominantly European-ancestry TCGA GBM dataset (EUR-GBM, n=383) revealed differential genomic and genetic landscape and immunological profile of EAS-GBM from EUR-GBM. EAS-GBM showed an enrichment for NF1, H3F3A, TP53 and ATRX mutations compared to EUR-GBM. Transcriptomic clustering revealed distinct EAS-GBM specific subtypes, namely Proliferative (PL), Neuron-Synaptic (NS), Metabolic (MB) and Immunomodulatory (IM). Notably, the classic subtype of EUR-GBMs with EGFR as its main marker gene was absent in EAS-GBMs, Moreover, the IM subgroup in EAS-GBM with an expression profile that has been previously associated with response to immunotherapy in cancers. Together, our comprehensive characterization revealed the unique genomic and genetic features of EAS-GBMs, providing mechanistic rationale in patient stratification for molecular targeted therapy and drug development in the era of personalized medicine.

e20015 Background: The Phase 3 IKEMA study (NCT03275285) demonstrated that isatuximab (Isa) plus carfilzomib and dexamethasone (Kd) significantly improved progression-free survival (PFS) compared with Kd in patients (pts) with relapsed multiple myeloma (RMM) (hazard ratio [HR] 0.53; 99% confidence interval [CI] 0.32–0.89; P= 0.0007). We evaluated the efficacy and safety of Isa-Kd in the East Asian patients (19 Japanese, 27 Korean). Methods: RMM pts who received 1-3 prior lines of therapy were stratified to receive Isa-Kd or Kd. Isa-Kd arm received Isa (10 mg/kg intravenously) weekly for 4 weeks, then every 2 weeks. Both arms received K (20 mg/m2 days 1-2, 56 mg/m2 thereafter) twice-weekly for 3 of 4 weeks, and d (20 mg) twice-weekly. Treatment continued until disease progression or unacceptable adverse events (AE). The primary endpoint was prolongation of PFS. Key secondary endpoints included; very good partial response or better (≥VGPR), complete response (CR) rate and minimal residual disease negativity (MRD–) rate. Results: East Asian pts (25 Isa-Kd, 21 Kd) were randomized. Pt characteristics were similar in the East Asian subgroup compared with the intent to treat (ITT) population (N = 302). Median age (Isa-Kd 64.0 [range 45–83] years vs Kd 60.0 [range 33–73] years); median prior lines Isa-Kd 2.0 (range 1–3) vs Kd 1.0 (range 1–3); refractory to lenalidomide 16.0% Isa-Kd vs 47.6% Kd; refractory to PI 20.0% Isa-Kd vs 33.3% Kd; high-risk cytogenetics 48.0% Isa-Kd vs 42.9% Kd. After a median follow-up of 20.7 months, the addition of Isa to Kd improved ≥VGPR, CR and MRD– rates (Table). The HR 0.64 (95%CI: 0.231-1.764) for disease progression or death favored Isa-Kd. Grade ≥3 AEs were observed in 79.2% Isa-Kd vs 55.0% Kd pts, serious TEAEs in 45.8% Isa-Kd vs 50.0% Kd; TEAEs leading to treatment discontinuation were lower in the Isa-Kd group (4.2% Isa-Kd vs 10.0% Kd). Overall, 64.0% Isa-Kd vs 42.9% Kd pts were still receiving treatment. Conclusions: Efficacy and safety results of Isa-Kd in East Asian pts are consistent with the results of the overall IKEMA population, in which significantly better efficacy (PFS, CR, ≥VGPR and MRD– rate) was reported in favor of Isa-Kd without an increase in the number of patients with serious TEAEs or discontinuations. Isa-Kd is a potential treatment option for East Asian pts with RMM. Clinical trial information: NCT03275285. [Table: see text]
