Clinical trials for solid tumors with IDH1 and IDH2 (IDH1/2) mutations are ongoing. Reports of IDH1/2-mutated non-small cell lung cancers (NSCLCs), however, are limited. METHODS We evaluated IDH1/2 mutations in 1,924 NSCLC specimens (92% adenocarcinoma) using a next-generation sequencing assay. RESULTS Retrospective quality assessments identified false detection of IDH1 c.395G>A (p.R132H) resulting from cytosine deamination (CG→TA) artifact in one specimen. IDH1/2 mutations were detected in 9 (0.5%) adenocarcinomas taken by fine-needle aspiration (n = 3), thoracentesis (n = 2) or core biopsy (n = 4). All nine adenocarcinomas showed high-grade features. Extensive clear cell change, however, was not observed. High expression (50% or greater) of PD-L1 was observed in two of five specimens examined. IDH1/2 mutations were associated with old age, smoking history, and coexisting KRAS mutation. Lower than expected variant allele frequency of IDH1/2 mutants and coexistence of IDH1/2 mutations with known trunk drivers in the BRAF, EGFR, and KRAS genes suggest they could be branching drivers leading to subclonal evolution in lung adenocarcinomas. Multiregional analysis of an adenocarcinoma harboring two IDH2 mutations revealed parallel evolution originating from a KRAS-mutated lineage, further supporting subclonal evolution promoted by IDH1/2 mutations. CONCLUSIONS IDH1/2 mutations in NSCLCs are uncommon. They occur in adenocarcinomas with high-grade features and may be branching drivers leading to subclonal evolution. Accumulation of more IDH1/2-mutated NSCLCs is needed to clarify their clinicopathological characteristics and implications for targeted therapy. © 2020 The Authors.

Studies have found evidence that circRNAs regulate programmed cell death, invasion, and metastasis and serve as biomarkers in renal diseases. Recently, circRNAs were identified in exosomes secreted by the kidneys. Nevertheless, the function of circRNA in renal diseases remains ambiguous. Given that circRNAs are regulators of gene expression, they may be involved in the pathology of multiple renal diseases. Additionally, emerging evidence is showing that circulating circRNAs may serve as novel biomarkers for renal disease. In this review, we have summarized the identification, biogenesis, degradation, and functions of circRNA and have evaluated the roles of circRNA in renal diseases. © 2020 The Authors.

This study was designed primarily to compare the immunogenicity of MSB11455 and Neulasta® . As secondary objectives, the safety and tolerability of MSB11455 and Neulasta® were also compared. Healthy adult subjects were randomized to either MSB11455 or Neulasta® , stratified by antipolyethylene glycol (PEG) antibody status at screening and study site. Subjects received a single subcutaneous dose of MSB11455 or Neulasta® (both 6 mg/0.6 mL) on day 1 of each of two study periods (same product in both periods), separated by a washout of 28-35 days. Immunogenicity samples were taken predose and up to day 84 post-first dose. Noninferiority was confirmed if the upper limit of the exact one-sided adjusted 95% confidence interval (CI) for the difference in antidrug antibody (ADA)-positive rates was  less then  10%. Safety was assessed throughout the study. Overall, 336 subjects were randomized and treated (N = 168 in each group). Noninferiority of MSB11455 over Neulasta® was demonstrated for immunogenicity; the difference in confirmed treatment-induced ADA-positive rate between MSB11455 and Neulasta® was -0.6% (upper limit of the exact one-sided adjusted 95% CI 6.25%). ADAs were mostly directed against the PEG moiety of pegfilgrastim. No filgrastim-specific neutralizing antibodies were detected in either treatment group. Safety and tolerability were as expected for pegfilgrastim, and comparable between treatments. This study supports and strengthens the available evidence for the biosimilarity of MSB11455 to Neulasta® . © 2020 The Authors.

Here, in a group of patients with mesial temporal lobe epilepsy (mTLE), we seek to confirm these EEG features, and using simultaneous functional magnetic resonance imaging, we investigate whether brain networks related to the alpha rhythm differ between patients and healthy controls. Additionally, we investigate whether alpha abnormalities are found as an inherited endophenotype in asymptomatic relatives. METHODS We acquired scalp EEG and simultaneous EEG and functional magnetic resonance imaging in 24 unrelated patients with unilateral mTLE, 23 asymptomatic first-degree relatives of patients with mTLE, and 32 healthy controls. We compared peak alpha power and frequency from electroencephalographic data in patients and relatives to healthy controls. We identified brain networks associated with alpha oscillations and compared these networks in patients and relatives to healthy controls.
