Clinical trials provide a foundation for new drug development processes, as well as for product license extensions for existing therapies. The reduction in the amount of time and cost to conduct a clinical trial becomes important, as competition to bring a new drug to the market is increasing, and so is the search for new markets. Kenya, Nigeria, Tanzania, Uganda, and Zambia offer a diverse patient population, as well as a comparatively research-friendly and ambitious government to develop these countries as pharmaceutical and health sectors of excellence. All these countries have their own guidelines to conduct clinical trials that feature some similarities and some subtle differences. Over the last decade, the guidelines have been evolving to provide a good ground to foreign sponsors, which carry out clinical trials while keeping the interest of patients as a priority. In the advent of these evolving guidelines, it becomes important for a foreign sponsor to understand and be aware of these guidelines before carrying out clinical trials. The present paper attempts to collect and compile all information available regarding the guidelines on the conduct of trials by a foreign sponsor in these five countries, which are available at government websites and search engines. The information gathered was organized into simplified flowcharts for easy understanding and usage. A clear understanding of the guidelines can effectively reduce the challenges faced for conducting clinical trials in these countries.
The coronavirus disease 2019 (COVID-19) has spread worldwide. It is still a pandemic and poses major health problem across the globe. In our review, clinical characteristics and laboratory parameters of COVID-19 patients were compiled systematically, with special reference to pregnant women in order to understand the disease course. An extensive literature search on various scientific databases for relevant manuscripts was conducted, which yielded 7 manuscripts for final analysis. The most common symptoms were fever (85%), cough (70.63%), chest tightness (37.36%), expectoration (33.27%), fatigue (32%), dyspnea (31.95%), and shortness of breath (31.19%), while hemoptysis (1.0%) was the least common. The associated comorbidities were hypertension (21.6%) and diabetes (10.0%). In terms of hematological parameters, lower total leukocyte counts were observed in 65% of cases and biochemical parameters, patients demonstrated elevated levels of albumin (53.72%), lactate dehydrogenase (45.71%), and natriuretic peptide (34.84%); however, total bilirubin was elevated in only 8% of cases. In the acute inflammatory cytokine profile, C-reactive protein (59.0%), tumor necrosis factor (58.0%), erythrocyte sedimentation rate (57.0%), interleukin-2 (IL-2, 54.0%), and IL-6 (52.0%) levels were increased, while prolactin levels (6.5%) were minimally elevated. The recovery rate was approximately 41%, and mortality was about 6.5%. The study also concluded that the clinical symptoms of COVID-19 were similar among pregnant and non-pregnant women. There was no evidence of vertical transmission of COVID-19 infection. This review critically analyzed COVID-19 as a public health hazard in order to help policy makers, health care givers, and primary physicians to promote early diagnosis and prevention.
Conduct of clinical trials has undergone substantial changes over the last two decades. Newer markets, evolving guidelines and documentation and high cost involved in conducting the trials have led pharmaceutical companies to prepare a risk mitigation plan. Extensive monitoring of potential risks is an essential element of clinical trials which helps to ensure quality and integrity of a clinical investigation. Every clinical trial has pre (before the trial), conduct and post phase. This article which has been developed as a result of extensive research at ground level by a reputed pharmaceutical company to identify the potential stages of risks that could affect the overall quality and safety of a trial and its outcome during the pre-phase of trial (the stage of the trial where the study design is being planned before initiation of the clinical trial). It includes risks associated with basic study concept, protocol design, Confidential Disclosure Agreement (CDA) and Clinical Trial Authorization (CTA) application signing, vendors of central drug laboratory, site and investigator selection, Clinical Research Coordinator (CRC) meet, Informed Consent Form (ICF), Case Report Form (CRF)/ Status Report Form (SRF) preparation, Ethics Committee (EC) submission, etc. have been highlighted. The risk based mitigation strategy (to develop an effective risk monitoring plan before staring a clinical trial) has also been suggested by authors. A well-tailored and integrated plan, recognition of potential risks and their mitigation strategy can result in the pre exclusion or end to end solution of all the risks associated with pre- phase of clinical trials.
As the number of clinical trials conducted are rising in the emerging markets, there is a need to understand and implement a robust PV system, where electronically globalized, evidence based, public health oriented and regulatory compliant PV system is established. This would also improve transparency in system and ensure enhancement in safety data reporting ensuring premature and trouble-free detection of ADRs. It might result in implementing various PV boosting activities, which could yield robust patient safety data from India and emerging markets.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
