Purpose:To evaluate the effectiveness of laser-assisted angioplasty for patients with critical limb ischemia (CLI) who were poor candidates surgical revascularization. Methods:A prospective registry at 14 sites in US and Germany enrolled 145 155 critically ischemic limbs; bypass surgery owing to inadequate target vessel or saphenous vein, prohibitive cardiac disease, significant comorbidities (ASA class 4). Additional comorbid risk factors included diabetes 66%, hypertension 83%, previous...
<p>Dose of hRS7 ATAC 1 and 2 with indicated dose α-amanitin used in BxPC-3 Capan-1 dose-response efficacy studies.</p>
<p>MS spectra of DAR determination. Western blotting TROP2 expression on PDAC cell lines. Internalization antibody in In vitro cytotoxicity ADCs MTD and efficacy studies. Spiderplot animals treated with ADCs.</p>
<p>Internalization of hRS7-LALA-DC antibody in PDAC cell lines. Flow cytometry gating was performed according to the PANC-1 cells that do not express TROP2.</p>
<p><i>In </i><i>vivo</i> antitumor efficacy of individual animals treated with Trodelvy compared to hRS7 ATAC 1 in TNBC xenograft mouse model. Female NMRI nude mice bearing HCC70 subcutaneous tumors were either PBS or the indicated doses (cleavable linker) Trodelvy. Efficacy was monitored for 76 days and evaluated by average tumor volume ±SEM, n = 10.</p>
<p>Western blotting of TROP2 expression on PANC-1, BxPC-3, Capan-1 and Capan-2 cells. hRS7-LALA-DC was used as primary antibody rabbit anti-human-IgG-HRP (Abcam) secondary antibody. Chemiluminescence signal detected by WB imager (Azure C400 imaging). The different apparent size TROP-2 in BxPC3 Capan 2 cells is most likely due to differential glycosylation [44] and/or from proteolytic cleavage [45]. In not detected, proteolytical resulting an isoform that cannot be the hRS7 [45], [46].</p>
<p>Deconvoluted MS spectra for hRS7 ATAC 1 (A) and (B) conjugates. The drug-to-antibody (DAR) ratio was measured using intact LC-MS analysis.</p>
<p>a. In vitro cytotoxicity of hRS7 ATAC 1 in tumor cells with medium (A; NCI-N87 cells) and low TROP-2 expression (B; MCF-7 b. PDAC upon transient acidosis or acid adaptation. BxPC-3 (TROP2+++) Capan-1 (TROP2++) were incubated at normal pH 6.6 for 24 hours, 7 days month then treated 96 hours 1. c. Trodelvy TNBC d. <i>In vitro</i> compared to cells.</p>
<p>MTD of hRS7 ATAC 1 and 2. The tolerability was assessed in 7-week-old tumor free female NMRI nude mice by single dose intravenous administration ATACs. At a 10 mg/kg 1, one three animals found dead within 48 h after treatment thus 8 considered to be MTD. ATAC2 tested up maximum 80 – no higher doses were tested. Therefore, the MTD ≥ mg/kg.</p>
<div>Abstract<p>Trophoblast cell surface antigen 2 (TROP2) exhibits aberrant expression in pancreatic cancer, correlating with metastasis, advanced tumor stage, and poor prognosis patients ductal adenocarcinoma. TROP2 has been recognized as a promising therapeutic target for antibody–drug conjugates (ADC), evidenced by the approval of anti-TROP2 ADC Trodelvy treatment triple-negative breast cancer (TNBC). In this study, we report generation novel second-generation amanitin-based...
Abstract Background: About half of the currently FDA-approved antibody drug conjugates (ADCs) are based on microtubule inhibitors, making them effective only against actively dividing cells. Non-dividing tumor stem cells in contrast cannot be eradicated and may cause resistance relapse. Hence, there is a high demand for novel payloads with unique modes action to overcome current limitations. Inhibition NAMPT, rate-limiting enzyme salvage biosynthetic pathway NAD+ starting from nicotinamide,...

Abstract Objective. Breast-conserving therapy with external beam radiotherapy (EBRT) is currently the standard of care for women early breast cancer. Our aim was to determine if early-stage cancers treated lumpectomy and primary intraoperative (IORT) have comparable local recurrence rates. This first study examining Canadian experience IORT. Methods. Patients who underwent breast-conserving pre-pathology IORT between 2007- 2017 were retrospectively identified. The outcome measure ipsilateral...
