OBJECTIVE: To describe and then compare an investigational carbapenem antibiotic, meropenem, with the only currently available antibiotic in this class, imipenem/cilastatin. DATA IDENTIFICATION: An English language search using MEDLINE (1988–1993); Abstracts of the 31st Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC), 1991; and Abstracts of the 32nd ICAAC, 1992. STUDY SELECTION: All current scientific publications were reviewed for study design and quality. Emphasis was placed on susceptibility and pharmacokinetic analysis. Phase 3 clinical trials are now being completed and have only been published in abstract form. Hence, conclusions derived regarding efficacy were tempered. RESULTS: Meropenem is active against a broad spectrum of gram-positive and -negative pathogens including beta-lactamase producers. Meropenem appears to be two- to fourfold less active than imipenem against gram-positive organisms. Meropenem is two- to fivefold more active against enterobacteriaceae. The two compounds appear to be equally active against Pseudomonas aeruginosa. Pharmacokinetic disposition is also similar for imipenem and meropenem. Meropenem may exhibit greater tissue penetration. Meropenem is not labile to renal hydrolysis and can be administered without a competitive antagonist of dihydropeptidase, such as cilastatin. In clinical trials, meropenem appears to be as safe and effective as imipenem/cilastatin or ceftazidime in the treatment of infections involving soft tissue, urinary tract, upper respiratory tract, abdominal processes, and febrile neutropenic episodes. CONCLUSIONS: Meropenem is comparable to imipenem in terms of in vitro susceptibility pattern and pharmacokinetic disposition. Overall, meropenem seems to offer promise as the second of the carbapenem class of antibiotics. Clinical data are preliminary, and further data are needed.

Abstract Pluripotent stem cells (PSCs) hold great potential for novel therapeutic approaches to regenerate or replace functionally impaired tissues. Since the introduction of the induced pluripotent stem cell technology in 2006, the number of scientific publications on this topic has constantly been increasing. However, so far no therapy based on PSCs has found its way into routine clinical use. In this study, we examined research trends related to clinical trials involving PSCs based on data obtained from ClinicalTrials.gov, the ICTRP database from the World Health Organization, as well as from a search of all individual databases that are included in the ICTRP using a multistep search algorithm. Following a stringent inclusion/exclusion procedure 131 studies remained that could be classified as clinical trials involving PSCs. The magnitude of these studies (77.1%) was observational, which implies that no cells were transplanted into patients, and only a minority of studies (22.9%) were of an interventional study type. The number of clinical trials involving induced pluripotent stem cells (iPSCs, 74.8%) was substantially higher than the one involving embryonic stem cells (ESCs, 25.2%). However, the picture changes completely when focusing on interventional studies, where in the majority (73.3%) of cases ESCs were used. Interestingly, also the study duration was significantly shorter for interventional versus observational trials (p = 0.002). When focusing on the geographical study regions, it became obvious that the greatest part of all observational trials was performed in the USA (41.6%) and in France (16.8%), while the magnitude of interventional studies was performed in Asian countries (China 36.7%, Japan 13.3%, South Korea 10.0%) and in the field of ophthalmology. In summary, these results indicate that only a limited number of trials were focusing on the actual transplantation of PSCs into patients in a rather narrow field of diagnoses. The future will tell us, if the iPSC technology will ultimately overcome the current challenges and will finally make its way into routine clinical use.

The Clinical Drug Experience Knowledgebase (CDEK) is a database and web platform of active pharmaceutical ingredients with evidence of clinical testing as well as the organizations involved in their research and development. CDEK was curated by disambiguating intervention and organization names from ClinicalTrials.gov and cross-referencing these entries with other prominent drug databases. Approximately 43% of active pharmaceutical ingredients in the CDEK database were sourced from ClinicalTrials.gov and cannot be found in any other prominent compound-oriented database. The contents of CDEK are structured around three pillars: active pharmaceutical ingredients (n = 22,292), clinical trials (n = 127,223), and organizations (n = 24,728). The envisioned use of the CDEK is to support the investigation of many aspects of drug development, including discovery, repurposing opportunities, chemo- and bio-informatics, clinical and translational research, and regulatory sciences.

BACKGROUND The Coronavirus Disease 2019 (COVID-19) pandemic presents a great public health challenge around the world, especially given the urgency to identify effective drugs and develop a vaccine in a short period of time. Globally, there are several drug and vaccine candidates currently in clinical trials, yet it is not yet clear which will prove successful. OBJECTIVE This study addresses this gap by mapping the treatments and vaccine candidates currently in clinical trials and assessing the opinions on these candidates of virus-related researchers from all over the world. METHODS Clinical trial data were obtained from ClinicalTrials.gov and the survey’s respondents were authors of recent scientific publications related to viruses, SARS virus, coronavirus, and COVID-19 indexed in the Web of Science Core Collection. RESULTS The results show that remdesivir, immunoglobulin from cured patients and plasma are considered the most promising treatments, and ChAdOx1 and mRNA-1273 the most promising vaccine candidates. They also indicate that a vaccine could be available within eighteen months. CONCLUSIONS Changes in the clinical trial process are currently being implemented worldwide in an attempt to accelerate the discovery of an entirely new vaccine to prevent COVID-19 8. These changes may be why the respondents felt it would take such a short time to develop a vaccine. Despite the relatively high percentage of unknown answers, which may be linked to the short-term perspective of this survey and the current uncertainties surrounding the subject at hand, the results of this survey suggest that the efforts made so far to accelerate the discovery of a new vaccine are in line with its purpose. If these expectations are confirmed, perhaps the discovery that will bring an end to the COVID-19 pandemic is not so very far away

e18112 Background: A plethora of targeted agents are currently being evaluated in patients with NSCLC. The number of targeted agents exceeds the number of targets leading to many targeted agents being evaluated against similar targets. The identification of new targets are likely to increase exponentially in the near future given the numerous currently ongoing molecular profiling efforts. The objective of this analysis is to estimate the target-specific patient resource utilization and its impact on routine clinical care. Methods: A comprehensive search for molecularly targeted agents in clinical testing that have accrued or are accruing NSCLC patients were performed by using publically available search engines and databases. Agents were grouped according to the primary target and the phase of development. We computed the number of patients allocated to completed and ongoing phase III NSCLC trials for advanced NSCLC alone. Results: There are more than 30 categories of molecular targets accruing NSCLC patients in clinical trials. By conservative estimates, approximately 215 agents are currently undergoing clinical testing. The median number of agents per target is 7 (range 2 (HIF-1α and PDGFRα) – 24 (EGFR)). There are 7 EGFR inhibitors and 10 VEGFR inhibitors that were evaluated in phase III trials; with 36,093 and 20,313 stage IV NSCLC patients enrolled or to be enrolled in these trials, respectively. No more than 2 agents per target have been FDA approved for NSCLC to date. Further details of the analyses will be more comprehensively presented at the meeting. Conclusions: Patient resource utilization is unevenly distributed across targets. The optimal number of targeted agents to be evaluated per target remains to be defined. More emphasis on identifying new targets and targeting these with limited number of optimal agents may accelerate the advancement of the field and the impact on patient care.
