Aim: We investigated the impact of proteinuria on the therapeutic effect before lenvatinib administration as second-line treatment after atezolizumab-bevacizumab.
Methods: We examined 64 patients who were administered lenvatinib as second-line treatment after discontinuation of atezolizumab and bevacizumab. Proteinuria assessed before lenvatinib administration was considered severe if the qualitative value test (QV) was 3+ or the urine protein/creatinine ratio (UPCR) was ≥ 2.0 (group A, = 13) and non-severe if the UPCR was < 2.0 or the QV was ≤ 2+ (group B, = 51).
Results: In the entire cohort, the modified albumin-bilirubin grades were grades 1, 2a, 2b, and 3 in 12, 21, 26, and 5 patients, respectively. Regarding the Barcelona Clinic of Liver Cancer stage, 2, 22, and 40 patients had stages A, B, and C, respectively. The objective response rate (ORR) was 14.0% and the disease control rate (DCR) was 59.3%. The median survival time and progression free survival after administration of lenvatinib was 14.8 (95% confidence interval [CI], 11.3-18.4) and 5.5 (95% CI, 3.6-7.5) months, respectively. The ORR and DCR were 0% and 38.4% for group A ( = 13) and 17.6% and 64.7% for group B ( = 51), respectively. The median time to treatment failure was 2.2 months in group A and 4.2 months in group B ( = 0.120).
Conclusions: Severe proteinuria before lenvatinib as a second-line therapy after atezolizumab-bevacizumab treatment may affect the duration of lenvatinib administration and treatment efficacy.

Pharmacokinetic exposure and treatment outcomes of lenvatinib in patients with renal cell carcinoma and differentiated thyroid carcinoma.

Purpose: After initial approval of lenvatinib for radioiodine-refractory differentiated thyroid cancer (DTC), it has also shown promising outcomes in among others metastatic renal cell carcinoma (mRCC). Given that trial populations typically do not represent routine clinical care populations, questions arise about how applicable trial outcomes are in clinical practice. This study aims to compare the pharmacokinetics (PK), toxicity patterns, and survival data of lenvatinib in a real-world cohort with DTC and mRCC to those observed in pivotal clinical trials.

Background: Lenvatinib is an oral tyrosine kinase inhibitor that selectively inhib-its receptors involved in tumor angiogenesis and tumor growth. It is an emerging first-line treatment agent for hepatocellular carcinoma (HCC). However, there is no intravenous ad-ministration of Lenvatinib.

Article Synopsis
- TACE is the standard treatment for patients with unresectable, non-metastatic hepatocellular carcinoma, and this study evaluates the effectiveness of adding lenvatinib and pembrolizumab to TACE compared to a placebo.
- The multicenter, randomised, double-blind phase 3 study (LEAP-012) involved participants from 137 sites across 33 countries who were randomly assigned to receive either TACE with the new drugs or TACE with a placebo.
- The primary endpoints were progression-free survival and overall survival, and the results reported are from the first interim analysis, which serves as the final analysis for progression-free survival.
Drug classes associated with the development of fulminant type 1 diabetes: a retrospective analysis using the FDA adverse event reporting system database.

Department of Endocrinology, Guang'anmen Hospital of China Academy of Chinese Medical Sciences, Beijing, China.
Background: Fulminant type 1 diabetes mellitus (FT1DM) is a severe subtype of type 1 diabetes characterized by rapid onset, metabolic disturbances, and irreversible insulin secretion failure. Recent studies have suggested associations between FT1DM and certain medications, warranting further investigation.
Objectives: This study aims to identify drugs associated with an increased risk of FT1DM using the FDA Adverse Event Reporting System (FAERS) database, evaluate reporting patterns, and provide actionable insights to reduce FT1DM occurrence and improve medication safety.
