The modern age of clinical trials, born with the British Medical Research Council’s study of streptomycin treatment of tuberculosis in 1948, has provided the substrate for evidence-based medicine. Clinical trials have been credited with “three of the seven years of increased life expectancy over that time and an average of five additional years of partial or complete relief from the poor quality of life associated with chronic disease”. The enormous expansion of clinical trials has paralleled the event of latest therapies. With the massive number of medicine in development and therefore the requirement for controlled clinical trials for approval, the expanding number of clinical trials isn't expected. Despite the obvious benefits of bringing scientific methods to the evaluation of therapies, the need for clinical trials has recently been challenged. Proponents of epidemiological studies as substitutes for clinical trials have suggested that conclusions from observational studies, including meta-analyses, often give similar answers as clinical trials. Although empirical data may provide useful information regarding established therapies, it should be obvious that they play a very different role from clinical trials.","PeriodicalId":15375,"journal":{"name":"Journal of clinical trials","volume":"1 1","pages":"1-1"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78533245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Only in Argentina, 50,000 deaths have been confirmed so far. There haven’t been so far any clear diagnostic pattern for this exceptional entity except unilateral skin involvement, early onset of symptoms, positive ANA and negative tests for Borrelia burgdorferi. Hence, we report a new case of a young Moroccan man. No treatment tested worldwide has shown unquestionable efficacy in the fight against COVID-19, according to W.H.O, NIH and NICE reports and accumulated data. Our proposal consists of the combination of drugs, based on the pathophysiology of the virus. We have designed a treatment called I.D.E.A., based on four affordable drugs already available on the pharmacopoeia in Argentina, on the following rationale: -Ivermectin (IVM) solution to lower the viral load in all stages of COVID-19. -Dexamethasone 4 mg injection, as anti-inflammatory drug to treat hyperinflammatory reaction to COVID-infection. -Enoxaparin injection as anticoagulant to treat hypercoagulation in severe cases. -Aspirin 250 mg tablets to prevent hypercoagulation in mild and moderate cases. Except for Ivermection oral solution, which was used in a higher dose than approved for parasitosis, all other drugs were used in the already approved dose and indication. Regarding Ivermectin safety, several oral studies have shown it to be safe even when used at daily doses much higher than those approved already. A clinical study has been conducted on COVID-19 patients at Eurnekian Hospital in the Province of Buenos Aires, Argentina. The study protocol and its final outcomes are described in this article. Results were compared with published data and data from patients admitted to the hospital receiving other treatments. None of the patient presenting mild symptoms needed to be hospitalized. Only one patient died (0.59% of all included patients vs. 2.1% overall mortality for the disease in Argentina today, 3.1% of hospitalized patients vs. 26.8% mortality in published data). I.D.E.A. protocol has proved to be a very effective alternative to prevent disease progression of COVID-19 when applied to mild cases, and to decrease mortality in patients at all stages of the disease with a favorable risk-benefit ratio.","PeriodicalId":15375,"journal":{"name":"Journal of clinical trials","volume":"20 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89357869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, PD is reported to have beneficial effects on autonomic disturbance in patients. Objective: The objective of the study is to investigate the effects of PD on autonomic nervous system of healthy adult subjects using spectral analysis of heart rate and blood pressure variability during Head-Up Tilt Test (HUTT). Here, we investigated the effects of PD on autonomic nervous system of healthy adults using spectral analysis of heart rate and blood pressure variability during Head-Up Tilt Test (HUTT). Methods: Twenty healthy subjects were divided into young and middle-aged groups, and examined twice with HUTT, before and 5 minutes after taking 5 g of PD. Spectral analysis of RR interval and Systolic Blood Pressure (SBP) variability was then used to measure the changes in autonomic functions. Results: As for all study participants, low frequency power of the SBP (SBP-LF) was increased, and high frequency power of RR interval (RR-HF) was decreased by tilt. However, PD did not show any effect on SBP-LF or RR-HF both at supine and tilt positions. Tilting did not change the ratio of low and high frequency power of RR interval (RRLF/ HF) before taking PD, which was increased after taking it. When analyzed separately by age, RR-HF was decreased in middle-aged group compared to the young counterpart in all conditions. Interestingly, PD increased RR-HF in middle-aged group at supine position, and a significant reduction of the value appeared at tilt similar like young group. After taking PD, tilt increased RR-LF/HF in both young and middle-aged groups. Conclusion: Our study finds that PD has a function to stimulate sympathetic nerve, and simultaneously restores the decreased parasympathetic functions in both young and elderly groups. Such findings suggest that PD might have a combined effect to protect the whole autonomic nervous system.","PeriodicalId":15375,"journal":{"name":"Journal of clinical trials","volume":"82 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77466501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to Hay et al. [1] the probability of drugs in phase III to get approved across different indications was only 50%. This is noteworthy in light of the fact that most drugs that make it into phase III have successfully completed phase II, this implies that they met the primary efficacy endpoint and had an acceptable safety profile. There are several possible reasons for this discrepancy between phase II and III success, sometimes drug company sponsors have such a strong financial and strategic interest to advance projects into phase III that they are willing to accept or even overlook obvious issues and risks. Alternatively, the phase II results may have simply been false positive as phase II studies are not always powered for significance, or the power may have been too low. In some rare cases, phase II may have been skipped altogether, this happens especially in indications where patients are enrolled in phase I, such as oncology. For clinical phases I and II the likelihood of approval is much lower (10.4%, 16.2%). These issues are exacerbated by the common practice to use adjusted historical success probabilities for go/no go decisions, although such historical averages can at best give a sense of direction. If agency issues and historical data not reflecting the candidates real profile come together, one gets a dangerous mixture leading to risky clinical trials. The effect of a failed phase III can be disastrous for smaller biotech companies (and their investors) but also larger companies are sometimes seriously affected and pushed into merger situations as a consequence of high profile phase III failures. But it is most disappointing for those patients who saw the participation in a clinical study as a real chance of improving their condition.","PeriodicalId":15375,"journal":{"name":"Journal of clinical trials","volume":"13 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75214093","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The author previously described the relationship between APRI (aspartate aminotransferase to platelet ratio index) and endothelial function assessed by Flow-Mediated Vasodilation (FMD), thereby suggesting that APRI may reflect systemic atherosclerosis condition in elderly patients without hepatic-related causes. Some reports of the relationship between NAFLD/NASH and atherosclerosis status and between chronic Hepatitis C Virus (HCV) infection and atherosclerotic state have been described. As both chronic liver disease and atherosclerosis involve severe inflammatory processes, at least common pathway may be present for the development and treatment of these inflammatory diseases. The current knowledge of the relationship between chronic liver diseases (NAFLD/NASH and HCV infection) and atherosclerosis and a novel therapeutic strategy is reviewed. Based on the several evidences, the author suggests that an association between chronic liver disease and systemic atherosclerosis may be present due to the presence of the inflammation as a common pathway. It is plausible that direct acting antivirus therapy is a potential strategy for not only liver disease but also endothelial dysfunction and atherosclerosis in patient with HCV infection. It has been suggested that momelotinib as a novel treatment may play a potential therapeutic benefit to a high-risk patients with NAFLD/NASH.","PeriodicalId":15375,"journal":{"name":"Journal of clinical trials","volume":"28 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74799108","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it is vital that pharmaceutical companies who sponsor clinical trials ensure that their data is accurate and timely. Numerous challenges for clinical trials exist and include recruitment and enrollment of appropriate research subject. Potential candidates for these studies are recruited and incentivized to participate in trials. While a great number of people participate in clinical trials solely for altruistic reasons, compensation for time and travel does motivate many potential research subjects. For others without adequate health insurance, the impetus is the evaluation and treatment with investigational products at no charge for their own potential health conditions. For both safety reasons and purposes of data integrity, it has long been held that research subjects should not volunteer in more than one study at a time. Also, there is typically a minimum 30-day waiting period or “washout period” between studies. These criteria are difficult to verify and thus we explored the development of a global regulatory compliant database that collects information on the exact research subject’s study history to detect multiple potential pitfalls and protocol violations that would be of immeasurable benefit to strengthen clinical trial data. Our study shows that subjects are neither always compliant nor forthcoming. There are attempts to screen more than once; there are age violations, washout period violations, and other violations that might cause poor quality data in a trial. Verified Clinical Trials (VCT) is the world’s largest and most comprehensive research subject database. By utilizing VCT, a sponsor can ensure that their subjects are verified and are not either enrolled in another clinical trial, still in their washout period, or in violation of any other protocol criterion.","PeriodicalId":15375,"journal":{"name":"Journal of clinical trials","volume":"82 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83931516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While a significant number of resources is used to improve treatment for high grade gliomas, there are few advancements in technology development towards an accurate non-invasive assessment of response to these therapeutic modalities. The advent of new treatment modalities and especially the increasing number of immunotherapy clinical trials for high grade gliomas necessitate the development of new approaches for accurate and timely assessment of treatment response in brain tumors. Conventional MRI assessment of response to immunotherapy is inadequate to guide treatment leading to a high number of surgical procedures for definitive assessment. In this review, we are outlining the evolution of imaging criteria as well as the advancements in imaging technology and computational analysis to address the challenges of disease monitoring in the setting of immunotherapy for high grade gliomas. We give particular emphasis on radiomics, a new field on image analysis that algorithmically assesses a large number of imaging features for an accurate diagnosis.","PeriodicalId":15375,"journal":{"name":"Journal of clinical trials","volume":"62 1","pages":"1-14"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88758500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
