Evidence of insufficient quality of reporting in patent landscapes in the life sciences

Despite the importance of patent landscape analyses in the commercialization process for life science and healthcare technologies, the quality of reporting for patent landscapes published in academic journals is inadequate

Adipose-derived stem cells in aesthetic surgery: a mixed methods evaluation of the current clinical trial, intellectual property, and regulatory landscape

Background: Adipose tissue, which can be readily harvested via a number of liposuction techniques, offers an easily accessible and abundant source of adipose-derived stem cells (ASCs). Consequently, ASCs have become an increasingly popular reconstructive option and a novel means of aesthetic soft tissue augmentation. Objectives: This paper examines recent advances in the aesthetic surgery field, extending beyond traditional review formats to incorporate a comprehensive analysis of current clinical trials, adoption status, and the commercialization pathway. Methods: Keyword searches were carried out on clinical trial databases to search for trials using ASCs for aesthetic indications. An intellectual property landscape was created using commercial software (Thomson Reuters Thomson Innovation, New York, NY). Analysis of who is claiming what in respect of ASC use in aesthetic surgery for commercial purposes was analyzed by reviewing the patent landscape in relation to these techniques. Key international regulatory guidelines were also summarized. Results: Completed clinical trials lacked robust controls, employed small sample sizes, and lacked long-term follow-up data. Ongoing clinical trials still do not address such issues. In recent years, claims to intellectual property ownership have increased in the “aesthetic stem cell” domain, reflecting commercial interest in the area. However, significant translational barriers remain including regulatory challenges and ethical considerations. Conclusions: Further rigorous randomized controlled trials are required to delineate long-term clinical efficacy and safety. Providers should consider the introduction of patient reported outcome metrics to facilitate clinical adoption. Robust regulatory and ethical policies concerning stem cells and aesthetic surgery should be devised to discourage further growth of “stem cell tourism.

An assessment of the factors affecting the commercialization of cell-based therapeutics: a systematic review protocol

Background Cellular-based therapies represent a platform technology within the rapidly expanding field of regenerative medicine and are distinct from conventional therapeutics—offering a unique approach to managing what were once considered untreatable diseases. Despite a significant increase in basic science activity within the cell therapy arena, alongside a growing portfolio of cell therapy trials and promising investment, the translation of cellular-based therapeutics from “bench to bedside” remains challenging, and the number of industry products available for widespread clinical use remains comparatively low. This systematic review identifies unique intrinsic and extrinsic barriers in the cell-based therapy domain. Methods/design Eight electronic databases will be searched, specifically Medline, EMBASE (OvidSP), BIOSIS and Web of Science, Cochrane Library and HEED, EconLit (ProQuest), WHOLIS WHO Library Database, PAIS International (ProQuest), and Scopus. Addition to this gray literature was searched by manually reviewing relevant work. All identified articles will be subjected for review by two authors who will decide whether or not each article passes our inclusion/exclusion criteria. Eligible papers will subsequently be reviewed, and key data extracted into a pre-designed data extraction scorecard. An assessment of the perceived impact of broad commercial barriers to the adoption of cell-based therapies will be conducted. These broad categories will include manufacturing, regulation and intellectual property, reimbursement, clinical trials, clinical adoption, ethics, and business models. This will inform further discussion in the review. There is no PROSPERO registration number. Discussion Through a systematic search and appraisal of available literature, this review will identify key challenges in the commercialization pathway of cellular-based therapeutics and highlights significant barriers impeding successful clinical adoption. This will aid in creating an adaptable, acceptable, and harmonized approach supported by apposite regulatory frameworks and pertinent expertise throughout the respective stages of the adoption cycle to facilitate the adoption of new products and technologies in the industry

Tools for the Diagnosis of Herpes Simplex Virus 1/2: Systematic Review of Studies Published Between 2012 and 2018 (Preprint)

BACKGROUND Herpes simplex virus (HSV)-1 and HSV-2 are common infections affecting the global population, with HSV-1 estimated to affect 67% of the global population. HSV can have rare but severe manifestations, such as encephalitis and neonatal herpes, necessitating the use of reliable and accurate diagnostic tools for the detection of the viruses. Currently used HSV diagnostic tools require highly specialized skills and availability of a laboratory setting but may lack sensitivity. The numerous recently developed HSV diagnostic tools need to be identified and compared in a systematic way to make the best decision about which diagnostic tool to use. The diagnosis of HSV is essential for prompt treatment with antivirals. To select the best test for a patient, knowledge of the performance and limitations of each test is critical. OBJECTIVE This systematic review has summarized recent studies evaluating HSV-1 and HSV-2 diagnostic tools. METHODS Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, selection criteria, data extraction, and data analysis were determined before the commencement of the study. Studies assessing the specificity/sensitivity of HSV-1 or HSV-2 diagnostic tools published between 2012 and 2018 were included. Quality assessment of included studies was performed using the quality assessment of diagnostic accuracy studies (QUADAS-2) tool. RESULTS Searches of the PubMed database yielded 264 studies; 11 studies included 11 molecular assays, and 8 studies included 19 different serological assays for the detection of HSV-1, HSV-2, or both. A greater proportion of molecular assay–based tools are being developed by commercial entities. Studies that tested molecular assays mostly focused on cutaneous and mucosal HSV infections (n=13); 2 studies focused on ocular disease, whereas only 1 study focused on the central nervous system manifestations. The Simplexa HSV 1 &amp; 2 Direct is currently the only Food and Drug Administration–approved device for use on cerebrospinal fluid. No tools focused on prenatal screening. We also present performance metrics of tests for benchmarking of future technology. Most of the included studies had a high risk of bias rating in half of the QUADAS-2 tool risk of bias domains. CONCLUSIONS The use of serologic tests to diagnose genital lesions is inappropriate because positive results may be due to chronic infection, whereas negative results may overlook recent infection. The incidence of acute infections is rising. As these infections present the greatest risk to fetuses, work needs to be done to prevent vertical transfer. Prenatal screening for primary infection and subsequent medical intervention will assist in lowering the rate of neonatal herpes. In conclusion, HSV diagnosis is moving away from culture-based methods to serology-based or polymerase chain reaction–based methods. Sensitive, rapid, and efficient HSV diagnostic tools should be adopted for the prevention of acute infections and neonatal herpes. </sec
