Impact of the COVID pandemic on functioning of the institutional ethics committee: A comparison study.

Purpose and Aim: In COVID 19 pandemic, it was essential to document the functioning of the institutional ethics committee (IEC), how the organization adapted and faced challenges posed, thus forming the rationale behind this particular audit. The objectives were to assess the impact of the pandemic on the structure, review process, outcomes, and administration of IEC and to compare the same during its functioning in the prepandemic stage. Subject and Methods: The study was conducted as a retrospective audit. After exemption from ethics review, the data were collected from the IEC office situated in KEM Hospital and were segregated into four domains: structure, review process, outcomes, and administration. The data were analyzed using descriptive statistics. Mann-Whitney U-test was used to compare the turnover time for approval of projects between the two study periods at 5% level of significance. SPSS software version 22 was used to analyze the data. Results: Constitution changed , more protocols pertaining to COVID 19 studies were reviewed, meetings frequency doubled, and Standard Operating Procedures was amended to incorporate the changes faced during pandemic. Significant decrease in turnover time was noticed with respect to submission to query letter and study completion. There were more protocol deviations. Financial burden and expenditure decreased due to less paperwork and meetings being held online. Conclusion: The ethics committee infrastructure and functioning had to undergo a paradigm shift to adapt to the various changes and overcome the various hurdles occurring during the COVID-19 pandemic.

Evaluation of clinical trials done for orphan drugs versus nonorphan drugs in infectious diseasesan eleven year analysis [2010-2020].

Background: The 1983 US Orphan Drug Act provided impetus for the development of new therapies for rare diseases. Several studies focused on the number of orphan designations over time. However, very few focused on clinical trials that lead to their approval, particularly for infectious diseases. Materials and Methods: All new drug approvals (orphan and non-orphan) by the US Food and Drug Administration (FDA) from January 2010 to December 31, 2020, were identified and details of approvals were taken from the US-FDA labels and summary reports for each drug. The pivotal trials for each were characterized based on their design. We tested the association of the type of drug approval with respect to the characteristics of trial using Chi-square test and generated crude odds ratios with 95% confidence intervals. Results: From the total 1122 drugs approved, 84 were for infectious diseases, of which 18 were orphan drugs and 66 were nonorphan. A total of 35 pivotal trials supported 18 orphan drug approvals, while 115 pivotal trials supported 66 nonorphan drugs. The median number of participants enrolled/trial for orphan drugs was 89, while for nonorphan drugs, it was 452 (P < 0.0001). Blinding was done for 13/35 (37%) orphan drugs versus 69/115 (60%) nonorphan drugs (P = 0.029); randomization was done for 15/35 (42%) orphan drugs versus 100/115 (87%) nonorphan drugs (P < 0.0001) and 20/35 (57%) of the orphan drugs got approval in phase II versus 8/115 (6%) of nonorphan drugs (P < 0.00001). Conclusion: A significant number of orphan drugs get approval based on early phase, nonrandomized, and unblinded with a smaller sample size as compared to nonorphan drugs.

An audit of institutional ethics committee queries raised after initial project submission by a single research department at a tertiary referral center in India.

Introduction: The institutional ethics committees (IECs) raise queries following protocol reviews. The quality of these queries would be a useful metric to assess how well the IEC executes its fundamental role of protecting participants. Methods: Queries received after the initial review and replies sent by a single research department were evaluated. A content analysis was done to identify the domains and categories of queries. We categorized these queries as administrative, ethics related, and scientific. The impact of each query in improving the science or safeguarding the rights and safety of research participants (ethics) was evaluated by two authors of this manuscript: one affiliated and the other nonaffiliated to the institute. Kappa statistics were used to evaluate for agreement between the two. Results: A total of 13 studies (investigator-initiated studies [IISs]: 7 and pharmaceutical industry-sponsored studies [PSSs]: 6) formed the final sample size for analysis. The total number of queries was 364 (IIS: 106 and PSS: 258; P < 0.001). With regard to the categories, we found n = 42 (11.54%) to be irrelevant at that stage of the review process; n = 51 (14.01%) were about information already available which the IEC had missed; n = 67 (18.41%) queries where the IEC needed paraphrasing; n = 50 (13.74%) were entirely relevant with the need for further clarification; and n = 154 (42.31%) had been missed by the investigator during the initial submission. The overall agreement between the affiliated and unaffiliated investigators was just 12.9% (P < 0.001). Conclusions: We found that approximately 25% of the queries raised by the IEC were redundant. It is our opinion that this redundancy could have been channeled into greater focus on scientific and ethical aspects of the protocol. Ongoing dialog between investigators and ethics committees may help address this. Perspectives between the affiliated and the unaffiliated investigators with regard to the relevance of queries were grossly different.

Evaluation of genetic polymorphism of CYP3A5 in normal healthy participants from western India - A cross-sectional study.

BACKGROUND: CYP3A5 enzymes belong to the phase I Group of drug-metabolizing enzymes, which are involved in the metabolism of 50% of the drugs. Participants with CYP3A5 genotype: CYP3A5 *1/*1 are fast metabolizers of drugs and hence will require higher dosing. Whereas those with CYP3A5 * 3/*3 are poor metabolizers of drugs and will require a lower dose to achieve target drug concentration in the blood and those with CYP3A5 * 1/*3 have intermediate drug metabolizing activity. Pharmacogenetic evaluation may improve disease outcomes by maximizing the efficacy and minimizing the toxicity of drugs in patients. MATERIALS AND METHODS: This is a single-center cross-sectional study conducted in the year 2018-2019 to study the population prevalence of genetic polymorphisms of CYP3A5 in healthy participants from western India. Eligible participants willing to give written, informed consent were enrolled in the study. Subsequently, 2 ml venous blood was collected the deoxyribonucleic acid was extracted and then stored at ‒20°C. Genotyping was done by a polymerase chain reaction and restriction fragment length polymorphism. RESULTS: A total of 400 participants with a median age of 22 years (range: 18-58 years) were included. Among them, the genotype prevalence for CYP3A5 * 1/*1 was 17% (n = 67/400); CYP3A5 * 1/*3 was 37% (n = 149/400) and that of CYP3A5 * 3/*3 was 46% (184/400). Out of the total 400 healthy participants analyzed, the allele frequency for CYP3A5 * 1 was 35% (142/400) and that of CYP3A5*3 was 65% (259/400). CONCLUSION: The genotype prevalence for CYP3A5 * 3*3 (46%) and the allele frequency for CYP3A5 * 3 (65%) respectively were the highest among the western Indian population.

Determination of reference intervals from a laboratory database of an academic clinical research unit in a tertiary care teaching hospital and an audit of out of range values.

BACKGROUND: Abnormal laboratory values are a common reason for the exclusion of participants in clinical studies, increasing the recruitment time and cost during conduct. The use of sample-specific reference intervals (RIs) may help to address this issue. Hence, the present study derived site-specific RIs using the department laboratory database and compare the proportion of "out of range" (OOR) values between the new and the old RIs used by the trial site. METHODS: Institutional ethics committee approval was obtained. Data for hematology and biochemistry parameters were analyzed. Normality was assessed and RIs computed using nonparametric method. Data were partitioned for gender and descriptive statistics applied for demographics. The OOR values based on new RIs were compared with old RIs using Chi-squared tests. Between gender OOR proportions compared using Chi-squared test (significance at P< 0.05). Post hoc analysis was performed with Beasley's technique. RESULTS: Data of 601 participants were analyzed. The median (Inter Quartile Range) age was 22 (47) years and 64.72% were male. New RIs for key parameters were: Haemoglobin (9.3-16.5 g/dl), alanine aminotransferase (11.4-47.74 U/I), aspartate aminotransferase (8.8-58 U/I), total bilirubin (0.27-1.4 mg/dl), and creatinine (0.59-1.36 mg/dl). Post partitioning, the RI for hemoglobin (g/dl) was lower (8.72-15.72) in females. The proportion of OOR values were lower with new RIs relative to old laboratory RIs (P < 0.0001). CONCLUSION: A reduction in the proportion of OORs and a change in the upper and lower bound laboratory intervals with new RIs emphasize the need for sample-specific ranges to prevent unnecessary exclusions of volunteers from trials.

Compliance of Mumbai-based clinical trial sites with the Quality Council of India guidelines and evaluation of the challenges faced by the investigators.

PURPOSE: A committee chaired by Dr. Ranjit Roy Chaudhary suggested accreditation of investigators, sites and ethics committees to improve the quality of trial conduct in the country. Prior to accreditation, understanding the challenges faced at the sites by investigators could help define the extent of the problem and identify potential solutions. Hence, we conducted the present study. METHODS: Institutional Ethics Committee approval and written informed consent was obtained prior to enrolment. A checklist and a questionnaire was used to assess compliance to Quality Council of India (QCI) standards and the challenges faced by the sites and investigators respectively. Mumbai based investigators listed in the Clinical Trial Registry of India (CTRI) were enrolled. The responses obtained were analysed descriptively. The responses to each question in the checklist were calculated as a proportion and response to each item in the questionnaire was calculated in frequency and percent frequency. All the analysis was done using Microsoft Excel version 2013. RESULTS: A total of 30 investigators from 69 clinical trial sites agreed to participate. We found that over 80% of the sites complied with standards recommended by the QCI guideline. The most frequently reported issues at the site were lack of space for archival (25%), no System to evaluate adequacy of training (31.81%) and lack of understanding of the technical language of the informed consent form (39.02%). CONCLUSION: There is a need of coordinated effort between all the stakeholders to improve the clinical trial conduct at the site.

A survey of knowledge and variables influencing perceptions about clinical research: A cross-sectional study from Mumbai.

PURPOSE: Clinical research in India has been besieged by controversies. While studies have addressed other stakeholders, few have addressed the patient. The present study was conducted to assess the extent of awareness and understanding about the nature and conduct of CR among people of Mumbai. METHODS: Institutional Ethics Committee approval was taken (EC/OA-12/15) and written informed consent was obtained. Adults who were residents of Mumbai were enrolled. A prevalidated and published 48-item questionnaire based on six themes, namely awareness and participation, voluntariness and autonomy, compensation, confidentiality, safety, and involvement in CR were administered. Perception based on themes and association of variables such as age, gender, socioeconomic class, and education on this perception was assessed. Descriptive statistics along with Chi-square test/Chi-square test for trend and crude odds ratio (cOR) were assessed. RESULTS: Of the 453 participants approached, 400 (age 32 [18-96]) consented. Only 210/400 (52.5%) were aware of CR and 194/400 (48.5%) said they needed permission for participation. Only 226/400 (56.5%) were aware of their rights and 111/400 (27.75%) felt that clinical trial participants received compensation. The socioeconomic class influenced awareness of CR (P < 0.00001; r 2= 0.495) as did the age (P < 0.0001; r 2= 0.82). Men were less likely to need permission to participate relative to women (cOR [95% confidence interval (CI)] 2.47 [1.6, 3.6] [P < 0.00001]). Those who had heard of CR were twice more willing to participate (cOR [95% CI] 1.72 (1.2, 2.6); P = 0.008). CONCLUSIONS: There is a greater need to improve awareness, especially about safety, compensation, and confidentiality in CR.

Association of Bacillus Calmette Guerin Vaccine Strains with COVID-19 Morbidity and Mortality - Evaluation of Global Data.

BACKGROUND: Literature suggests that the presence of the current Bacillus Calmette Guerin (BCG) policy appears to mitigate COVID-19 disease burden but no information exists on the nature of the BCG strain and disease burden. OBJECTIVES: To study the association between type of BCG strain, BCG coverage (%), and COVID-19 disease burden. METHODOLOGY: An audit of global data on strains and disease burden was done. Country-specific data for COVID-19 cases and deaths, BCG-related data, and income level were obtained from the online databases, and the association was analyzed using linear regression. RESULTS: Data of 139 countries were studied and 117 (84%) had a current BCG policy. Data on BCG strains were available for 51 countries and 18/51 (35%) used the Danish strain. While the choice of strain did not impact COVID-19-related disease burden, the presence of a current BCG policy was significantly associated with lower COVID-19 mortality. CONCLUSION: The presence of current BCG policy is associated with decreased COVID-19-related disease burden, but the type of strain used by a country in its vaccination program does not impact disease burden.

The global initiative for asthma guidelines (2019): change in the recommendation for the management of mild asthma based on the SYGMA-2 trial - A critical appraisal.

The Global Initiative for Asthma (GINA) recently released their updated Global Strategy for Asthma Management and Prevention Guide (2019). The pocket guide for practicing clinicians states that "the 2019 GINA strategy report represents the most important change in asthma management in 30 years." An important recommendation is the change in treatment strategy for the management of mild asthma where the guideline recommends that" all adults and adolescents with asthma should receive either symptom driven (in mild asthma) or daily low dose inhaled corticosteroid (ICS) containing controller treatment to reduce the risk of serious exacerbations." Our study critically appraises the SYGMA-2 trial, a key trial that largely formed the basis of this recommendation and discusses the potential consequences of using only long-acting beta-2-agonist + ICS as needed as against regular, daily low-dose ICS with as-needed short-acting beta-2-agonist. Our critique covers airway inflammation, disease heterogeneity, understanding the noninferiority margin and its consequences, the Hawthorne effect, and conflict of interest. It is our view that statement of this magnitude will have far-reaching implications for clinical practice which will be in the interests of some patients but also against the interests of others.

A Multicentric, Prospective, Observational Antibacterial Utilization Study in Indian Tertiary Referral Centers.

RATIONALE: Antibacterials are largely prescribed to the intensive care unit (ICU) patients due to high prevalence of infections. However, appropriate use of antibacterials is imperative; since the misuse of antibacterials increases antibacterial resistance and ultimately, it has negative impact on health care and economic system. Hence, continuous antibacterials prescription assessments are very important to judge and improve prescription patterns. The present work was carried out at public and private hospitals to assess the differences in antibacterial prescribing pattern. METHODS: The present study was conducted at three public and two private hospitals over the period of 14 months. Demographic and drug use details were captured daily from patients admitted to medical ICUs to assess the World Health Organization indicators. RESULTS: A total of 700 patients were enrolled across the five centers (140 per center), among them 424 were male and 276 were female. Average number of drugs and antibacterials prescribed at public hospitals are significantly higher than the private hospital. However, percentage of antibacterial agents prescribed at public hospitals was significantly lower than the private hospitals (P = 0.0381). Private hospitals had significantly lower percentage of antibacterial agents prescribed by generic name (P < 0.0001). Differences in change of antibacterial agents required were not statistically significantly different (P = 0.1888); however, significant difference was observed in percentage of patients who received antibacterial treatment as per sensitivity pattern (P = 0.0385) between public and private hospitals. Significantly higher mortality was observed in public hospitals compared to private hospitals (<0.0001). CONCLUSIONS: More generic prescriptions and more number of prescriptions as per the sensitivity pattern are required at each public and private hospital.

An analysis of completeness and quality of adverse drug reaction reports at an adverse drug reaction monitoring centre in Western India.

PURPOSE/AIM: The Adverse Drug Reaction [ADR] form is the source document for the Pharmacovigilance Programme of India [PvPI] and captures information first hand from the patient. The raw data from it then gets converted into an individual case safety report [ICSR] after entry into Vigiflow. The National Coordinating Centre [NCC] uses an instrument to assess quality of these ICSRs. We carried out the present study to assess whether the same instrument with minor modifications could be used to check the quality of ADR forms at our centre. MATERIALS AND METHODS: ADR reports of three months from three consecutive years were selected randomly. The ADR form [18 fields] was matched with the NCC instrument [14 fields] as the latter is made from the former. A perfect ICSR would score 1. Three fields in the NCC instrument - case narrative, compliance with standard operating procedures [SOPs] and free text [5 components] were modified, while the rest were retained. Zero was given to the first two fields. In the third field, we retained only 3/5 components and changed the last two components [sender and reporter comments] to dechallenge and rechallenge while keeping the total score the same. RESULTS: A total of 1008 ADR reports were analyzed. We found an overall completeness score of approximately 80% with the lowest completeness score being for the year 2015. The mandatory fields had close to 100% scores. CONCLUSION: The NCC instrument was found well suited to evaluate quality and completeness of ADR forms.

Evaluation of factors that motivate participants to consent for non-therapeutic trials in India.

BACKGROUND AND RATIONALE: Several factors that motivate individuals to participate in non-therapeutic studies have been identified. This study was conducted as limited data is available regarding these motivations from developing countries. METHODS: This was a single-centre study conducted over 4 months in which a questionnaire was administered to 102 healthy participants and 16 patient participants who had earlier taken part in non-therapeutic studies at our centre. Descriptive statistics and univariate analysis were used to analyse data. RESULTS: The most common motivation among healthy participants was financial reward (65%) followed by altruism, free medical check up, curiosity and personal health benefit. Patient participants, however, most commonly said they consented to take part in the trial as they were 'invited to participate by the treating physician' (88%). In comparison with the patient participants, healthy participants were more likely to be satisfied with the financial reward (p=0.02), and recommend participation in studies to friends or relatives (p=0.0013). CONCLUSIONS: The most common motivating factor to participate in non-therapeutic studies appears to be different for healthy participants (financial reward) and patient participants (invitation to participate by the physician). Participants also felt that adequate information and care was given to them during the trial, and that they would participate in future clinical studies, and would also recommend such studies to their friends.
