Lenvatinib Compared with Sorafenib as a First-Line Treatment for Radioactive Iodine-Refractory, Progressive, Differentiated Thyroid Carcinoma: Real-World Outcomes in a Multicenter Retrospective Cohort Study.

Background: Sorafenib and lenvatinib have been widely adopted to treat radioactive iodine (RAI)-refractory differentiated thyroid carcinoma (DTC). However, limited data exist regarding a direct comparison of these tyrosine kinase inhibitors (TKIs). We aimed to evaluate the clinical efficacy and safety of two TKIs as first-line therapy in patients with distant metastatic or locally advanced, progressive, RAI-refractory DTC in real-world practice. Methods: In this multicenter, retrospective cohort study, we evaluated 136 patients with progressive distant metastatic or locally advanced, progressive, RAI-refractory DTC or poorly differentiated thyroid carcinoma (PDTC) who received first-line sorafenib or lenvatinib treatment. The primary outcome was progression-free survival (PFS). We also evaluated the objective response rate, disease-control rate, clinical benefit rate, and safety. Results: The median age of the patients was 68 years, and 35% (47/136) were male. Eighty and fifty-six patients were included in the sorafenib and lenvatinib groups, respectively. The median PFS was 13.3 months [95% confidence interval, CI, 9.9-18.1 months] in the sorafenib group and 35.3 months [CI, 18.2 months to upper limit not reported as the median was not reached] in the lenvatinib group (p = 0.001). A significantly prolonged PFS was observed in the lenvatinib group (compared with the sorafenib group) after adjusting for age, sex, pathology, disease-related symptom, lung-only metastasis, cumulative RAI dose, time from diagnosis, treatment duration, and longest diameter of the target lesion (hazard ratio = 0.34, CI, 0.19-0.60, p < 0.001). The partial response rate was 24% and 59% in the sorafenib and lenvatinib groups, respectively (p < 0.001). More common grade 3-4 adverse events were hypertension (16%, 9/56 vs. 1%, 1/80, p = 0.002) and proteinuria (32%, 18/56 vs. 0%, p < 0.001) in the lenvatinib group, and hand-foot skin reaction (24%, 19/80 vs. 4%, 2/56, p = 0.001) in the sorafenib group. Conclusion: In our study of Asian patients, first-line lenvatinib treatment of metastatic or locally advanced, progressive, RAI-refractory DTC or PDTC was associated with a longer PFS compared with sorafenib. However, severe hypertension and proteinuria were observed more frequently after lenvatinib treatment than after sorafenib treatment.

Efficacy and Safety of Omega-3 Fatty Acids in Patients Treated with Statins for Residual Hypertriglyceridemia: A Randomized, Double-Blind, Placebo-Controlled Clinical Trial.

BACKGROUND: Cardiovascular risk remains increased despite optimal low density lipoprotein cholesterol (LDL-C) level induced by intensive statin therapy. Therefore, recent guidelines recommend non-high density lipoprotein cholesterol (non-HDL-C) as a secondary target for preventing cardiovascular events. The aim of this study was to assess the efficacy and tolerability of omega-3 fatty acids (OM3-FAs) in combination with atorvastatin compared to atorvastatin alone in patients with mixed dyslipidemia. METHODS: This randomized, double-blind, placebo-controlled, parallel-group, and phase III multicenter study included adults with fasting triglyceride (TG) levels ≥200 and <500 mg/dL and LDL-C levels <110 mg/dL. Eligible subjects were randomized to ATOMEGA (OM3-FAs 4,000 mg plus atorvastatin calcium 20 mg) or atorvastatin 20 mg plus placebo groups. The primary efficacy endpoints were the percent changes in TG and non-HDL-C levels from baseline at the end of treatment. RESULTS: After 8 weeks of treatment, the percent changes from baseline in TG (-29.8% vs. 3.6%, P<0.001) and non-HDL-C (-10.1% vs. 4.9%, P<0.001) levels were significantly greater in the ATOMEGA group (n=97) than in the atorvastatin group (n=103). Moreover, the proportion of total subjects reaching TG target of <200 mg/dL in the ATOMEGA group was significantly higher than that in the atorvastatin group (62.9% vs. 22.3%, P<0.001). The incidence of adverse events did not differ between the two groups. CONCLUSION: The addition of OM3-FAs to atorvastatin improved TG and non-HDL-C levels to a significant extent compared to atorvastatin alone in subjects with residual hypertriglyceridemia.

Quetiapine regulates the stress-induced increase in corticotropin-releasing factor mRNA expression in the rat hypothalamus.

Corticotropin-releasing factor (CRF) is a key regulator of the stress response. We investigated the effects of the atypical antipsychotic drug quetiapine on CRF mRNA expression in the rat hypothalamus following immobilization stress. Pretreatment with 10 mg/kg quetiapine significantly reduced the immobilization stress-induced increase in CRF mRNA expression in the paraventricular nucleus of the hypothalamus. These results suggest that quetiapine may modulate the stress response via regulation of CRF mRNA expression.
