Background: The recommended starting dose of cabazitaxel for castration-resistant prostate cancer (CRPC) is 25 mg/m in Japan and Europe. Although lower doses are established alternatives based on randomized controlled trials, the safety and efficacy of 25 and 20 mg/m in real-world settings are not well established. Therefore, we investigated the safety and efficacy of cabazitaxel at the recommended starting dose or a lower dose (20 mg/m) in real-world clinical practice.

Objectives: Data on the safety and efficacy of cabazitaxel in patients aged ≥80 years with castration-resistant prostate cancer (CRPC) are limited. We report the safety (adverse drug reactions [ADRs]) and efficacy (overall survival [OS], time to treatment failure [TTF], and prostate-specific antigen [PSA] response rates) in patients aged <80 or ≥80 years treated with cabazitaxel for CRPC in clinical practice.

Materials And Methods: We performed post-hoc subgroup analyses of a Japanese post-marketing surveillance study involving 662 patients with CRPC treated with cabazitaxel between September 2014 and June 2016.

Article Synopsis
  • The study aimed to assess the real-world safety and efficacy of cabazitaxel in Japanese patients with metastatic castration-resistant prostate cancer who had previously been treated with a docetaxel regimen.
  • A total of 660 patients were enrolled, with common adverse reactions including neutropenia, febrile neutropenia, and anemia; the majority of these occurred in the first treatment cycle.
  • The results showed that cabazitaxel had a safety profile similar to previous studies and demonstrated effectiveness through PSA response rates, overall survival, and time to treatment failure.

Aims And Introduction: We aimed to explore concomitant orally administered antidiabetic agent (OAD) regimens used in basal supported oral therapy (BOT) with insulin glargine in a real-life setting, and to assess the efficacy and safety of each regimen using data from the Add-on Lantus to Oral Hypoglycemic Agents 2 study, a 24-week observational study in Japanese type 2 diabetes patients.

Materials And Methods: Among 1629 insulin-naïve patients who had a glycosylated hemoglobin (HbA1c) value of ≥6.5 % during the previous 4 weeks and were treated with BOT during the observational period, 1227 patients who retained the same concomitant OAD regimens throughout the period were included in the analysis.

Objectives: We aimed to identify diabetes-related factors associated with achieving HbA1c <7.0 % after the initiation of basal supported oral therapy (BOT) in insulin-naïve type 2 diabetes patients with an HbA1c value of ≥6.5 % during the previous 4 weeks, using data from Add-on Lantus to Oral Hypoglycemic Agents 2 (ALOHA2) study, a 24-week observational study on Japanese type 2 diabetes patients.

Introduction: This study aimed to assess treatment satisfaction and self-reported health status in insulin-naïve patients with type 2 diabetes mellitus (T2DM) who started insulin glargine basal-supported oral therapy (BOT) with glycated hemoglobin (HbA1c) value of ≥6.5%, using data from Add-on Lantus(®) to Oral Hypoglycemic Agents 2 (ALOHA2) study, a 24-week single-arm, observational study of Japanese patients with T2DM, conducted as drug use surveillance in Japan.

Methods: Treatment satisfaction was measured using the Diabetes Treatment Satisfaction Questionnaire status version (DTSQs) and change version (DTSQc) and self-reported health status using EuroQol 5 Dimension (EQ-5D).

An on-chip electrochemical flow immunoassay system for the detection of hemoglobin A1c (HbA1c) was developed using anti-human hemoglobin (Hb) IgG labeled with ferrocene monocarboxylic acid (Fc-COOH) and boronate-affinity chromatography. An on-chip column packed with boronate-activated agarose beads was used for the separation of HbA1c from both non-glycated Hb and free antibody. Anti-human Hb IgG conjugated to Fc-COOH (Fc-IgG) was used for the electrochemical detection of HbA1c.
