Preclinical quality, safety, and efficacy of a human embryonic stem cell-derived product for the treatment of Parkinson’s disease, STEM-PD

Cell replacement therapies for Parkinson’s disease (PD) based on transplantation of pluripotent stem cell-derived dopaminergic neurons are now entering clinical trials. Here, we present quality, safety, and efficacy data supporting the first-in-human STEM-PD phase I/IIa clinical trial along with the trial design. The STEM-PD product was manufactured under GMP and quality tested in vitro and in vivo to meet regulatory requirements. Importantly, no adverse effects were observed upon testing of the product in a 39-week rat GLP safety study for toxicity, tumorigenicity, and biodistribution, and a non-GLP efficacy study confirmed that the transplanted cells mediated full functional recovery in a pre-clinical rat model of PD. We further observed highly comparable efficacy results between two different GMP batches, verifying that the product can be serially manufactured. A fully in vivo-tested batch of STEM-PD is now being used in a clinical trial of 8 patients with moderate PD, initiated in 2022

Safety and tolerability of bazedoxifene in postmenopausal women with osteoporosis: results of a 5-year, randomized, placebo-controlled phase 3 trial

Summary: Findings from this 5-year phase 3 study of postmenopausal women with osteoporosis showed that bazedoxifene was associated with an overall favorable safety and tolerability profile, with no evidence of endometrial or breast stimulation. Overall, the results at 5 years were consistent with those seen at 3 years. Introduction: We report safety and tolerability findings from a 5-year randomized, double-blind, phase 3 study of bazedoxifene in postmenopausal women with osteoporosis. Methods: In the core study, healthy postmenopausal women with osteoporosis (N=7,492; mean age, 66.4 years) were randomized to daily doses of bazedoxifene 20 or 40 mg, raloxifene 60 mg, or placebo for 3 years. During the 2-year study extension, the raloxifene 60-mg treatment arm was discontinued after the 3-year database was finalized, and subjects receiving bazedoxifene 40 mg were transitioned in a blinded manner to bazedoxifene 20 mg (bazedoxifene 40-/20-mg group) after 4 years. Safety and tolerability data are reported for subjects in the bazedoxifene 20- and 40-/20-mg and placebo groups; efficacy findings are reported elsewhere. Results: A total of 3,146 subjects in the bazedoxifene 20- and 40-mg and placebo groups were enrolled in the extension study (years 4 and 5). Overall, the 5-year incidence of adverse events (AEs), serious AEs, and discontinuations due to AEs were similar among groups. The incidence of hot flushes and leg cramps was higher with bazedoxifene compared with placebo. Venous thromboembolic events, primarily deep vein thrombosis, were more frequently reported in the bazedoxifene groups compared with the placebo group. Reports of cardiac disorders and cerebrovascular events were few and evenly distributed among groups. Bazedoxifene showed a neutral effect on the breast and endometrium. Conclusion: Bazedoxifene was associated with an overall favorable safety and tolerability profile in postmenopausal women with osteoporosis over 5 years of therapy, consistent with findings at 3 years. © 2010 International Osteoporosis Foundation and National Osteoporosis Foundation

Elevated levels of interleukin-12/23p40 may serve as a potential indicator of dysfunctional heart rate variability in type 2 diabetes

Abstract Background Systemic inflammatory processes plausibly contribute to the development of cardiovascular complications, causing increased morbidity and mortality in type 2 diabetes. Circulating inflammatory markers, i.e., interleukin (IL)-6 and tumour necrosis factor-α, are associated with neurocardiac measures. We examined a broad panel of various inflammatory and inflammation-related serum markers to obtain more detailed insight into the possible neuro-immune interaction between cardiovascular regulation and systemic level of inflammation. Methods Serum samples from 100 participants with type 2 diabetes were analysed. Heart rate variability, cardiovascular autonomic reflex tests, and cardiac vagal tone tests were performed based on electrocardiographic readings. Data regarding covariates (demographic-, diabetes-, and cardiovascular risk factors) were registered. Results Increased serum levels of IL-12/IL-23p40 (
