Background:The Therapeutic Angiogenesis by Cell Transplantation (TACT) trial demonstrated the efficacy and safety of autologous bone marrow-derived mononuclear cells (BM-MNCs) in patients with critical limb ischemia (CLI). The present study aimed to assess the long-term clinical outcomes of therapeutic angiogenesis using autologous BM-MNC implantation under advanced medical treatment in Japan. Methods and Results:The study was retrospective, observational, and non-controlled. We assessed no-option CLI patients who had BM-MNC implantation performed in 10 institutes. Overall survival (OS), major amputation-free (MAF), and amputation-free survival (AFS) rates were primary endpoints of this study. The median follow-up duration was 31.7 months. The 10-year OS rate was 46.6% in patients with arteriosclerosis obliterans (ASO) (n=168), 90.5% in patients with thromboangiitis obliterans (TAO) (n=108), and 67.6% in patients with collagen disease-associated vasculitis (CDV) (n=69). The 10-year MAF rate was 70.1%, 87.9%, and 90.9%, respectively. The 10-year AFS rate was 37.8%, 80.9%, and 61.2%, respectively. Major adverse cardiovascular events occurred in 6.0% of patients with ASO, 1.9% of patients with TAO, and no patients with CDV.Conclusions: Therapeutic angiogenesis using autologous BM-MNC implantation may be feasible and safe in patients with no-option CLI, particularly those with CLI caused by TAO or CDV.Key Words: Bone marrow-derived mononuclear cells; Critical limb ischemia; Therapeutic angiogenesis ORIGINAL ARTICLE Peripheral Vascular DiseaseAdvance Publication by-J-STAGE KONDO K et al.previous (5 years) or current history of neoplasms, diabetes with untreated retinopathy, age >80 years, the possibility of pregnancy, or the lack of informed consent. 6 We obtained written informed consent from all patients, and the ethics committees of the participating hospitals approved the protocol. Data CollectionWe developed a web-based database using FileMaker Pro (FileMaker, Inc., Santa Clara, CA, USA) and an electronic clinical record form (eCRF) to collect information about patient characteristics, previous medical history, adverse events, and outcomes on the last day on which the physician confirmed the patient's status. All patient data were stored and analyzed independently at the Center for Advanced Medicine and Clinical Research, Nagoya University Hospital, Nagoya, Japan. In 2015, 14 Japanese hospitals participated in this part of the TACT trial. Data were collected with the permission of the Ministry of Health, Labour, and Welfare.This study was retrospective, observational, and noncontrolled. The primary endpoints were the rates of overall survival (OS), major amputation-free (MAF), and amputation-free survival (AFS). AFS in this study included OS and major amputation. The safety of the therapy was assessed in the context of major adverse cardiovascular events (MACE; death, non-fatal myocardial infarctions, decompensated heart failure, and stroke) and all-cause adverse events during the 6-month follow-up period after ...

IntroductionProgestin therapy is the only fertility-sparing treatment option for patients with atypical endometrial hyperplasia (AEH) and endometrial cancer (EC). However, the results of three meta-analyses revealed a high remission rate, as well as an association with a high rate of relapse. We previously conducted a phase II of medroxyprogesterone acetate (MPA) plus metformin as a fertility-sparing treatment for AEH and EC patients, and reported that metformin inhibited disease relapse after remission.Methods and analysisA randomised, open, blinded-endpoint design phase IIb dose response trial was planned to commence in July 2019. The trial aims to identify the appropriate dose of metformin to be combined with MPA therapy for fertility-sparing treatment of patients with AEH and EC. The primary endpoint of the trial is the 3-year relapse-free survival (RFS) rate. The secondary endpoints are RFS rate, the overall rate of response to MPA therapy, the conception rate after treatment, the outcome of pregnancy, toxicity evaluation and changes in insulin resistance and body mass index. A total of 120 patients will be enrolled from 15 Japanese institutions within a 2.5-year period and followed up for at least 3 years.Ethics and disseminationThe protocol was approved by the institutional review board at Chiba University Hospital and boards at 14 other institutions. The trial will be conducted according to the principles of the World Medical Association’s Declaration of Helsinki and in accordance with Good Clinical Practice (GCP) standards. The trial findings will be published in a peer-reviewed journal.Trial registration numberJapan Registry of Clinical Trials (jRCT2031190065).

Patients with epidermal growth factor receptor (EGFR)-mutated non-small cell lung cancer (NSCLC) harboring BIM deletion polymorphism (BIM deletion) have poor responses to EGFR TKI. Mechanistically, the BIM deletion induces preferential splicing of the non-functional exon 3-containing isoform over the functional exon 4-containing isoform, impairing TKI-induced, BIM-dependent apoptosis. Histone deacetylase inhibitor, vorinostat, resensitizes BIM deletion-containing NSCLC cells to EGFR-TKI.In the present study, we determined the safety of vorinostat-gefitinib combination and evaluated pharmacodynamic biomarkers of vorinostat activity.
