036), a positive tumor lymph node metastasis (p=0.014), a poor differentiation status (p=0.003) and a poor prognosis (p=0.001). Combination of CA242 and CXCL5 expression (p less then 0.0001) served as a better prognostic factor than CA242 alone (p=0.006). In addition, PDAC patients with high CXCL5 expression had more intratumoral M2 polarized macrophages (p=0.0248), neutrophils (p=0.0068) and IgG+ plasma cells (p=0.0133) than patients with low CXCL5 expression. Conclusions The expression of CXCL5 is elevated in pancreatic cancer cells. High CXCL5 expression is positively correlated with poor survival and the increased infiltration of several types of immune suppressive cells. Thus, CXCL5 could be a promising therapeutic target for PDAC immunotherapy. © The author(s).Background Bevacizumab (BEV), a monoclonal antibody against vascular endothelial growth factor-A (VEGF-A), is a standard component of medical therapy of metastatic colorectal cancer (mCRC). Activation of alternative angiogenesis pathways has been implicated in resistance to BEV. This phase II study examines the activity of combined vertical blockade of VEGF signaling with sorafenib and BEV as salvage therapy in patients with progressive disease (PD) on all standard therapy in mCRC. Methods mCRC patients with documented PD on standard therapy, received sorafenib (200 mg orally twice daily, days 1-5 and 8-12) and BEV (5 mg/kg intravenously, day 1) every 2 weeks. Primary endpoint was 3-month progression-free survival (PFS) rate and secondary endpoints were overall survival (OS), response rate (RR), safety, and feasibility. Triapine Results Of the 83 patients enrolled, 79 were evaluable. Of these, 42 (53%) were progression-free at 3 months. Median PFS was 3.5 months and median OS was 8.3 months. One patient had a partial response and 50 patients (63.3%) had at least one stable tumor assessment. Of 79 evaluable patients, 54 (68%) experienced grade 3/4 adverse events (AEs) at least possibly related to treatment. Most frequent grade 3/4 AEs were fatigue (24.1%), hypertension (16.5%), elevated lipase (8.9%), hand-foot skin reaction (8.9%), diarrhea (7.6%), and proteinuria (7.6%). Reasons for treatment discontinuation were PD (72%), AEs (18%), patient refusal (8%), physician decision (1%), and death (1%). Conclusions The combination of BEV and sorafenib as salvage therapy in heavily pretreated mCRC patients is tolerable and manageable, with evidence of promising activity.

Methods A 15-week, phase II, double-blind, placebo-controlled clinical trial was conducted to assess the efficacy and safety of flexible-dose PF-06649751 in subjects with early stage Parkinson's disease (ClinicalTrials.gov identifier NCT02847650). Results Enrollment was terminated early for reasons unrelated to the trial. Overall, 57 subjects received study medication (PF-06649751 = 29; placebo = 28) and 47 completed the study (PF-06649751 = 25; placebo = 22). Despite early termination, the study met its primary endpoint with the PF-06649751 group showing statistically significant improvement from baseline in the Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part III score at week 15 compared with placebo. Mean (SE) change in MDS-UPDRS Part III score was -9.0 (1.54) for PF-06649751 and -4.3 (1.65) for placebo. This corresponds to an improvement versus placebo of 4.8 for the PF-06649751 group (two-sided p = 0.0407; 90% CI = 1.0, 8.6). Statistically significant improvement in MDS-UPDRS-III score was also observed at all assessment time points prior to week 15. The safety profile of PF-06649751 was similar to that observed in prior studies, with the majority of adverse events (AEs) reported as mild or moderate. The most common AEs in the PF-06649751 group were nausea, headache, dry mouth, somnolence, and tremor. Conclusions Once-daily dosing of oral PF-06649751 resulted in significant improvement of motor symptoms and was generally well tolerated in subjects with early stage Parkinson's disease. © The Author(s), 2020.Background The goal of the present cohort study was to review outcomes of patients exposed to interferon beta-1b during pregnancy. Methods Pregnancy cases with exposure to interferon beta-1b reported to Bayer's pharmacovigilance (PV) database from worldwide sources from January 1995 through February 2018 were retrieved for evaluation. Only cases where pregnancy outcomes were unknown at the time of reporting (i.e. prospective cases) were included in the analysis of this retrospective cohort study. Results As of February 2018, 2581 prospective pregnancies exposed to interferon beta-1b were retrieved from the database; 1348 pregnancies had documented outcomes. The majority of outcomes [1106 cases (82.0%)] were live births. Health status was known for 981 live births (no known health status for 125). Most of the prospective pregnancies with known outcomes corresponded to live births with no congenital anomalies [896 cases (91.3%)]. Spontaneous abortion occurred in 160 cases (11.9%). Congenital birth defects were observed in 14/981 live births with known health status [1.4%, 95% confidence interval (CI) 0.78-2.38]. No consistent pattern in the type of birth defect was identified. Rates of both spontaneous abortion and birth defects were not higher than the general population. Conclusions These PV data, the largest sample of interferon beta-1b-exposed patients reported to date, suggest no increase in risk of spontaneous abortion or congenital anomalies in women exposed during pregnancy. © The Author(s), 2020.Coronaviruses (CoVs) infect many species causing a variety of diseases with a range of severities. Their members include zoonotic viruses with pandemic potential where therapeutic options are currently limited. Despite this diversity CoVs share some common features including the production, in infected cells, of elaborate membrane structures. Membranes represent both an obstacle and aid to CoV replication - and in consequence - virus-encoded structural and nonstructural proteins have membrane-binding properties. The structural proteins encounter cellular membranes at both entry and exit of the virus while the nonstructural proteins reorganize cellular membranes to benefit virus replication. Here, the role of each protein in membrane binding is described to provide a comprehensive picture of their role in the CoV replication cycle. © 2019 Ian M Jones.
