Chapter I INTRODUCTION Background of the Study Clinical research has undergone a long and fascinating journey of development with clinical trials having faced ethical, legal, and scientific difficulties throughout history. The earliest known study of legumes was conducted in biblical times, while the first randomized controlled trial of streptomycin took place in 1946. (1) Clinical trials are research studies conducted to evaluate the safety and efficacy of medical treatments, interventions, or procedures on human subjects. The first notable work in terms of clinical trials dates back to the First Controlled Trial by James Lind (1747), wherein sailors afflicted with scurvy were divided into different groups and systematically tested with various treatments to determine the most effective remedy. (3) In the 1800s, the emergence of placebo created another milestone in the history of modern clinical trials. Hooper's Medical Dictionary of 1811 defined it as “an epithet given to any medicine more to please than benefit the patient.” Nevertheless, it wasn't until 1863 that American physician Austin Flint organized the first clinical study comparing a placebo to an active treatment. (4) In the 20th century, the field of controlled trials has become more sophisticated and ethical with the introduction of the Nuremberg Code, the Declaration of Helsinki, the Belmont Report, and the 1996 International Conference on Harmonization's establishment of Good Clinical Practice guidelines. These standards were set to ensure 1 safety and efficacy of medical interventions and proceedings protecting the rights of both research participants and researchers. (1) The ancient Hippocratic Oath, which stated that a doctor's primary responsibility is to prevent harming their patients, is where the ethical foundation for human subject protection first emerged. Nevertheless, there was little regard for this pledge in the field of human experimentation, and the majority of advancements in safeguarding human subjects have been made in response to abuses committed by people. The Nuremberg Code, the first international guidelines on the ethics of medical research involving human participants, was developed in 1947. While informed consent for research participation was first described in 1900, the Nuremberg Code emphasized the need for this consent to be voluntary. The 1948 Universal Declaration of Human Rights, which was ratified by the UN General Assembly, addressed the issue of human rights being violated by involuntary maltreatment. The tragedy surrounding the use of thalidomide by pregnant women played a role in the United States' passage of the 1962 Kefauver-Harris amendments, which enhanced federal control over drug testing and mandated informed consent. More stringent regulatory procedures were put in place, and double-blind research was adopted as routine procedure. Phase I clinical trials were early safety assessments, while Phase III large-scale efficacy studies were the evolution of clinical trials with the addition of placebo controls and discrete stages. (10) Continuous modernization and advancements in the late 20th century until present has allowed more precise and efficient trials. The globalization of clinical research, adaptive trial designs, and a growing emphasis on patient-centric approaches have further shaped the landscape of clinical trials in the 21st century, reflecting an 2 ongoing commitment to improving the scientific rigor and ethical standards of medical research. Patient participation in clinical trials has been a more crucial component of its successes in recent years. The key objectives of clinical trials are to provide safe, effective medicines to patients and to answer research questions more quickly for all those involved, including patients, regulators, sponsors, and academics. (2) Several clinical trials have been listed in the WHO International Clinical Trials Registry Platform (ICTRP) for the last two decades. Clinical research in a country is influenced by various factors, including the size of the population, the level of healthcare infrastructure, and research funding. The Philippines has been an active participant in conducting clinical trials, but in contrast to larger countries like the United States of America, China and Japan, the numbers are significantly smaller in comparison. Specifically, in the Philippines, 2,245 clinical trials have been registered to the ICTRP from 1999 to 2022. (12) Geographic disparities in the Philippines manifest as a concentration of academic institutions and clinical trials in Luzon, particularly Manila, leading to uneven healthcare (18) access and research opportunities across regions. This centralization is driven by factors such as the well-developed infrastructure, economic concentration, and superior accessibility in Luzon compared to other areas. Consequently, individuals outside Luzon face challenges in accessing advanced medical treatments and participating in clinical trials, perpetuating healthcare inequalities. Additionally, the absence of comprehensive clinical trial registries hinders a nationwide understanding of clinical trials, limits the identification of potential trial participants, and impedes effective treatment monitoring. Sociocultural considerations 3 further complicate matters, influencing how communities perceive and engage with clinical trials. Addressing these challenges requires a holistic approach involving infrastructure development, the establishment of comprehensive registries, community engagement initiatives, and policy changes to promote the equitable distribution of healthcare resources and research opportunities throughout the Philippines. Understanding the awareness and willingness of the public to participate in clinical trials is significant for shaping effective healthcare policies and advancing medical research. While the importance of clinical trials is widely acknowledged, specific insights into public perceptions and readiness to engage in such trials remain understudied, particularly in the context of residents of Tacloban City. This study aims to fill this gap by investigating public awareness, perceived attitude, and willingness to participate in clinical trials and research studies. The study also aims to contribute valuable insights to guide future healthcare initiatives. The findings are expected to benefit the general public, medical practitioners, public health agencies, and clinical researchers by informing decision-making, improving program implementation, and enhancing the design of future clinical research in the local community. 4 Research Objectives General Objective: The study aims to determine the perceived awareness, attitude, and willingness to participate in clinical trials and research studies among adult residents of Barangay 99 Diit, Tacloban City, Leyte.

H4 ; There is a significant relationship between the participants’ perceived awareness and their attitude towards clinical trials and research studies. 7 Conceptual Framework In this section, the conceptual framework, Perceived Awareness, Attitude, and Willingness to Participate in Clinical Trials and Research Studies are the three central variables. Awareness is influenced by information sources, knowledge level, demographic and clinico-demographic factors whereas, attitude refers to a way that a behavior is interpreted or understood. Willingness to participate, on the other hand, is influenced by perceived awareness and attitude. This study will describe and analyze the perceived level of awareness, attitude, and willingness to participate in clinical trials and research, emphasizing the relationship between the three variables and the various factors that may contribute to or hinder participant engagement. 8  The ultimate outcome is to determine whether the perceived awareness and attitude of the residents being potential participants in clinical trials influences the level of willingness to participate in clinical trials and research studies. The study will focus on recognizing factors that can influence the perceived awareness, attitude, and willingness among adult residents of Barangay 99 Diit, Tacloban City, Leyte. Limitations include the potential for self-reporting bias and the inability to account for all contextual variables influencing participant decisions. Significance of the Study The researchers believe that the findings of this study will directly or indirectly benefit the following: Adult Residents. Individuals, Families, and Communities will have a baseline of their awareness, perceived attitude, and willingness towards participating in clinical trials. This would lead to better decision making when it comes to their own health. They would also gain knowledge of the benefits both health related and financial that they may receive, the risks that they may encounter during and after participating in clinical trials, and laws that protect them from these risks. Clinicians and Other Medical Practitioners. Both government and nongovernment organizations will benefit from the study by gaining an outlook of the general public toward new and upcoming interventions. Thus, improving the implementation of current and future health programs pertaining to health promotion and disease prevention. 9 GOs, NGOs, and other Private Institutions. It will serve as a paramount for private health agencies as this will help develop patient-centered strategies, improve engagement, and foster trust. Comprehending the public will help enable tailored educational programs, ethical considerations, and develop targeted recruitment and retention approaches. Thus, private agencies can stand out in the crowded healthcare market by matching their procedures to the interests and worries of prospective participants. This will build their credibility and preserve the general integrity of clinical research and make a significant contribution to medical progress while preserving the well-being of the public. Researchers. The study would provide a baseline for researchers towards the level of awareness, perceived attitude, and willingness of individuals that may participate in current and upcoming clinical trials. This would also include barriers that may interfere with implantation of clinical trials and integrate adjustments for future studies. Scope and Limitation The study will focus on the perceived awareness, attitude, and willingness of a specific community to participate in clinical trials and research studies. Since the research relies on self-reported data from participants, the findings may be influenced by biases or misinformation, affecting the precision of the data obtained and the accuracy of the results. The study will target adult residents of Barangay 99 Diit, Tacloban City, aiming to understand their perspectives on participating in clinical trials and research studies. Given the diverse health conditions within the community, this 10 study seeks to provide meaningful contributions that can guide future healthcare strategies and foster the development of community-centered clinical research projects. Definition of Terms The following terms are defined within the context of how they apply to the research: Clinical Trials - It refers to the type of research that studies new tests and treatments and evaluates their effects on human health outcomes. People volunteer to take part in clinical trials to test medical interventions including drugs, cells and other biological products, surgical procedures, radiological procedures, devices, behavioral treatments and preventive care. (12) Awareness - having prior knowledge about an item, event, or phenomena. Awareness in the context of this research refers to the level of knowledge and understanding that individuals possess regarding the existence, purpose, and nature of clinical trials. It encompasses the extent to which potential participants are informed about clinical research, including its goals, processes, and potential benefits and risks. (9) Willingness - Willingness to learn is defined as an impulse, desire, or readiness to acquire new and developing knowledge.(6) Within the scope of this study, willingness pertains to the individual's readiness and openness to engage in clinical trials. It encompasses the psychological inclination and readiness of participants to actively consider and potentially participate in clinical trials. Age - It refers to the length of time a person has lived or existed. Sex - This refers to the biological and physiological characteristics that define humans as female or male. 11 Religion - refers to a set of organized beliefs, practices, and systems that most often relate to the belief and worship of a controlling force, such as a personal god or another supernatural being. Highest educational attainment - refers to the level of formal education completed by an individual, ranging from primary education to advanced degrees, providing an indication of their educational achievements. Employment Status - refers to the current state of an individual's engagement in paid work or occupation, indicating whether they are employed, unemployed, or not in the labor force. Marital Status - refers to the social standing of an individual in relation to marriage or non-marriage, encompassing categories such as single, married, divorced, widowed, or separated. Comorbidities - refers to a person's simultaneous presence of one or more extra illnesses or disorders in addition to the main illness that is being studied (15). Within the scope of the study, Comorbidities is defined as the pertinent health issues or pre-existing medical conditions among adult residents of Tacloban City. Comorbidities can affect a person's health status and general thoughts about participating in medical research, which can have an impact on their perceived awareness, attitude, and willingness to participate in clinical trials and research studies. Attitude - refers to subjective opinions or perspectives regarding research studies and clinical trials. It includes their general beliefs, sentiments, and tendency to take part in these kinds of medical research studies.(16) Attitude in this study may be influenced by 12 factors such as perceived benefits, risks, trust in the research process, and the impact of clinical trials on personal health and well-being. 13  CHAPTER II REVIEW OF RELATED LITERATURE This section outlines the literature utilized in the research. The studies outlined herein played a crucial role in providing the researchers with a comprehensive perspective, shaping the significance of the study and guiding the formulation of research objectives. Within this literature review, the researchers will find evidence, perceptions, and findings essential for the discourse on study variables. The central focus of this chapter revolves around clinical trial variables, namely: Awareness in clinical trials, Perceived attitude towards clinical trials, and Perceived willingness to participate in clinical trials. Related Literature Clinical trials have played a crucial role in paving the way for remarkable advancements in the field of medicine over the last few decades. Despite these achievements, numerous diseases lack effective treatments, and some existing ones are either inadequate or come with undesirable side effects. Therefore, there is a pressing need to enhance these treatment options. Clinical trials hold significance as they provide essential evidence for doctors and patients to determine the most effective treatments tailored to specific patient types. Without such evidence, there is a potential risk of administering treatments that offer no benefits or could even pose harm. (1) 16  It is essential for the participants to possess comprehensive knowledge about the trial and feel at ease seeking information. Sufficient knowledge and awareness can aid participants in fruitful discussions. The decision to participate in a clinical trial is highly personal, considering this, the participants should gather sufficient information and make decisions based on their own judgment as this enables them to volunteer which may directly contribute to enhancing our understanding of diseases and their treatment. (2) Understanding clinical trials is essential, empowering individuals to make well-informed choices about their health. This awareness guarantees a grasp of the possible advantages, risks, and contributions to medical progress linked to participation in clinical trials. Moreover, being well-informed cultivates trust in the research process, promoting increased engagement and cooperation in advancing scientific understanding and enhancing healthcare results.(1) Furthermore, the recruitment of suitable participants for the right trials, ultimately contributing to the advancement of medical research and healthcare. The role of health care providers in raising awareness is emphasized, with patients reporting that their participation in trials was often influenced by their providers. The clarity and guidance provided by healthcare professionals in explaining trials, presenting pros and cons, and assisting in finding suitable trials contribute significantly to patients' decision-making processes. (10) Various factors influence recruitment levels in clinical trials, with a significant feature being the first involvement of potential participants to encourage their consideration for trial participation. For clinical trials to achieve their goals, effective participant recruiting is essential. Inadequate recruiting within an appropriate time 17 frame puts the trial's capacity to address its main research issue in jeopardy in addition to increasing expenses and logistical challenges. In addition, inadequate recruitment impedes the timely provision of trial results, which in turn affects how clinical practices are shaped.(3) Misconceptions and inadequate communication were found to be major obstacles to clinical trial participation during a recent meeting hosted by cancer organizations. The wide range of participants—which included representatives from many industries, healthcare experts, and patient advocates—came to the conclusion that the general public is not well-informed about clinical trials and their potential advantages. A major cause of potential misunderstandings was brought to light by the summit: a general lack of coordination in the communications, resources, and assistance pertaining to the clinical trials process.(5) Thus, utilizing the use of social media and the internet becomes essential to raising awareness and increasing participation in clinical trials. These platforms provide a widely available and convenient way to connect with potential participants, facilitating the sharing of trial details, qualifying requirements, and advantages. Similarly, when it comes to general information about COVID-19 in Egypt, the internet and social media emerge as the predominant sources, aligning with findings from a comparable survey in Jordan. The popularity of online platforms for health-related information underscores their accessibility and immediacy. However, it is crucial to acknowledge the potential downside, as both the internet and social media can also be conduits for misinformation. Therefore, there is a pressing need to educate the public on discerning reliable sources when seeking information about clinical trials. (4) 18  There is a wide range of factors that influence the public’s perception towards clinical trials. It is important to keep in mind that people can have a wide range of attitudes due to the differences in their knowledge, experiences and backgrounds. Nonetheless, it has been reported that the difficulties stem from mistrust, lack of awareness and misinformation to the public. However, the study showed that among the participants that cited ‘fear’ and ‘mistrust’ as a reason for declining to participate belonged to a higher social class(6). In developing countries, people with lack of awareness and having misinformation from mainstream media might get the idea of clinical trials as somewhat negative and the participants were treated as “experimental rodents” and would perceive clinical trials as cruel to people being experimented on(7). Leaving an impression to the public that Clinical Trials are science fiction horror-esque made by “evil corporations” that would cause potential harm or cause them pain as people would be undergoing unfavorable and potentially life-threatening situations(8). Moreover, these concerns raised can be resolved through increased public to clinical researcher engagement(6). Nevertheless there is a major rise in spreading awareness in this age of information about the benefits of clinical trials in the betterment of research and development and would clear the bad publicity of Clinical Trials in the General Public, there are ways in means of educational and infographical mediums that would address the misconception and reduce the negative perception towards clinical trials(8). There are also subjects who previously participated or undergone Clinical Trials would perceive it in a positive manner and would emphasize its importance for 19 the improvement and advancement of science, much more than those who never participated nor had common knowledge about Clinical trials(7). Age is one of the determining factor to participate in clinical trials as some people wants to improve their own health status as some of those shown to be willing to participate has terminal illnesses caused by age related diseases and these people are hoping to receive new treatment that could potentially extend their life.(8) As people tend older as they are more likely to experience several conditions at the same time, they create a sense of urgency to prolong their lives and/or protect themselves and their families from different diseases that might cause harm in the future.(4) Younger adults would perceive the significance of clinical trials as less of a priority especially since they are much healthier than older adults would tend to be uninterested in participating in clinical trials, also the availability of younger adults is scarce especially since most of them are working full time jobs and would not consider participating. (20) There is a study done in which religious leaders of different religions experimental medicine and treatment that are currently used in clinical trials(16). They emphasized that the patient or participants should have basic knowledge and proper information of the origin of the medicine or treatment used, especially if it is animal derived, as some religions (Hindus, Sikhs and Muslims) consider animals as their deities and would not be willing to partake or participate further in the clinical trials. (17) As in the case of human derived products, some religions would approve of participating as long there is informed consent given. However, in case of extreme 20 urgency and there were no available alternative options, all of the participants would approve undergoing these treatment methods regardless of its origin. (16) Related Studies The primary barrier to subjects' participation in biomedical research is a lack of public awareness concerning the inclusions and the attributed effects associated with them. This hesitancy is strengthened by a lack of public understanding about biomedical research, which discourages people from taking part and becoming clinical trial subjects. As a result, there is an urgent need to prop public awareness of biomedical research to boost people's willingness to engage in such studies. (21) Numerous studies have explored patient perceptions of Clinical Trials in different countries, including the US, Denmark, Australia, and Japan (26). However, the applicability of these findings to regions with diverse sociocultural backgrounds emphasizes the importance of considering social, cultural, and economic perspectives when designing studies.(10) Limited empirical research in developing countries, including the Middle East, underscores the need for further investigations into knowledge, attitudes, and perceptions regarding CT participation.(11) Participants, often referred to as Trial Participants (TPs), are fundamental to the success of clinical trials, contributing to the understanding of diseases, the improvement of treatment therapies, assessment of treatment safety and efficacy, and the exploration of innovative ways to prevent, detect, or treat diseases.(12) However, amidst the promising landscape of the pharmaceutical industry, concerns have been raised regarding the unethical conduct of certain clinical trials. 21 Instances of drugs being tested on individuals without proper consent or prior toxicology studies on animals have been reported, raising ethical concerns and emphasizing the need for greater scrutiny in the conduct of clinical trials.(12) Various studies advocate for the positive impact of creating public awareness, citing changes in attitudes toward clinical trials, increased enrollment, and heightened recognition of the benefits of participation. The global recognition of the need for transparency, accountability, and accessibility in clinical trials underscores the importance of re-establishing public trust in these endeavors.(13) Some, including the Harris Interactive Survey (14) demonstrate that awareness significantly influences attitudes toward clinical trials and enrollment. A large percentage of patients were unaware of clinical trial options at the time of diagnosis. However, when provided with information, a substantial portion expressed willingness to enroll. Focus groups revealed that negative attitudes toward participation changed positively after participants gained familiarity with clinical trials, emphasizing the transformative power of awareness.(15) There are several factors that would affect an individual’s perceptions and attitudes towards clinical trials. These factors would include the demographic background, beliefs, and experiences unique to every individual. One factor that would prove to be a barrier was the lack of trust towards pharmaceutical companies. This may stem from the lack of trust that pharmaceutical companies would keep the participants' personal information private. Other determinants would include educational attainment and profession. Those individuals working in the health sector had a higher correlation of knowledge-attitude and knowledge-perception. 22 However, with these same individuals, the correlation of attitude-perception was lower as compared to non-healthcare workers. Furthermore, knowledge about clinical trials was gained mainly through social media acting as a medium through which the general public can access information on clinical trials, its benefits and risks, and its effects on themselves and the world. Hence, increasing engagement with the general public on clinical trials through social media may lead to a more positive perception and attitude. (18) Effective enlisting and involvement of human subjects determine the success and progress of biomedical research. However, in various forms of biomedical studies, human engagement is lacking, posing a significant issue for researchers in the field.(22) The willingness of participants to grant consent and engage in biomedical research, specifically in clinical trials, is highly influenced by socio demographic factors, including but not limited to education, income, and religion.(23) The inherent complexity of clinical trials makes enrollment challenging as individuals' willingness to participate might also be influenced by factors including standard of living, geographic location, disease load, fear of clinical trial procedures, adverse effects, poor knowledge, limited time, and mistrust of investigational items. (24) A study in Nepal found that age, education level, family structure, counsel from family and friends, and medical supervision all had a substantial impact on patients' desire to participate in vaccine clinical trials. The study also discovered that fear of blood samples was not a significant influence, contrary to clinical researchers' opinions. The primary concerns of potential participants were vaccine safety, injection frequency, and vaccine cost. (24) 23  Moreover, a study conducted in Korea found people who were aware of CTs were substantially more likely to participate than those who were not. This observation is consistent with past reports. Furthermore, the study found that respondents with a greater comprehension of CTs had a more positive willingness to participate than those with insufficient understanding. These findings emphasize the importance of understanding CTs in effectively recruiting and maintaining participants for the study. According to the survey, most respondents had a fundamental awareness of CTs via mass media sources such as TV or radio.(25) As a result, mass media campaigns could be a useful strategy for raising CT awareness, as previous research has suggested. (26) In addition, a study revealed a strong link between positive perception, notably in terms of safety and good feelings, and individuals' willingness to participate in CTs. Participants who believed CTs were highly safe were approximately 11 times more likely to engage than those who were less assured of their safety. These data suggest that one of the major hurdles to participating in CTs is the worry of potential side effects from drugs or treatments.(27) Previous research has also identified pharmacological side effects as the major cause of refusal to participate in CTs, as well as recruiting issues for people concerned about being given a less effective treatment option.(28) Mistrust in the informed consent procedure, as well as building a trusting connection with doctors, can also be barriers to CT participation.(29) For example, the Tuskegee Study, which purposefully misled participants and caused harm, has reduced African Americans' desire to participate in medical research studies.(30) As a 24 result, excellent communication between researchers and participants is critical to establishing confidence and facilitating CT engagement. Researchers must devote significant time to providing balanced information on the rewards and dangers of involvement, as well as explaining the predicted unpleasant reactions or drawbacks and the appropriate responses in such instances. Above all, adherence to research ethics, which establish guidelines for protecting human rights and maximizing research benefits while avoiding risks and ensuring distributive justice for CT participants during trials, is the most important factor in CT success.(31) A study conducted on the public attitudes and support for medical research, wherein a random digit dial telephone survey was conducted with 489 individuals in southwestern Pennsylvania.(19) The study revealed that 46% of respondents expressed a willingness to participate in a medical research study focused on a new treatment for a disease of personal concern, while 25% stated they would not be willing, and 29% remained undecided. Notably, specific circumstances, such as having cancer, influenced over half of the initially undecided respondents to express willingness to participate. There were several determinants that influenced participants' willingness to engage in medical research. Which included having a relative or friend with an illness, being middle-aged (35-64 years old), prior experience with research participation, having a favorable attitude toward using human subjects in medical research, and the belief that a diverse range of individuals participate in clinical trials. In addition, respondents who were undecided about participating in a clinical trial exhibited different characteristics compared to those not willing. Determinants of 25 being undecided, as opposed to being unwilling, included having at least a college degree, a favorable or neutral attitude toward the use of humans in medical research, and the belief that researchers prioritize the well-being of participants. Findings of the study carries both public policy and practical implications. From a policy perspective, an evidence-based approach to decision-making in medical research necessitates a sufficient number of willing participants. On a practical level, the study suggests opportunities to increase participation by tailoring recruitment efforts not only to those willing but also to those who are undecided. This approach involves customizing communication content to address the specific characteristics and concerns of each group, thereby fostering greater public engagement in medical research studies.(19) Synthesis This study presents the transformational impact of awareness, attitude and willing willingness of the participants in relation to the difficulties of clinical trials. A better informed and involved public can be achieved through health education, clearing up misconceptions, and promoting positive attitudes using a variety of channels, such as social media and focused communication techniques. The understanding that each person's choice to take part in a clinical study is extremely personal highlights the necessity of using individualized and considerate methods when sharing information. Although social media and the internet have made knowledge more accessible than ever before, there is a chance that false information may be spread. Establishing confidence and promoting participation requires striking 26 the correct balance between providing accurate, trustworthy information and allowing trial specifics to be widely disseminated. In addition, Age, religious views, and socioeconomic background are just a few of the many that shape public attitudes, underscoring the necessity of customized strategies in educational initiatives. Understanding that people with diverse backgrounds could have different goals and concerns calls for a nuanced and culturally aware strategy to meet these differing viewpoints. Furthermore, it is impossible to overestimate the importance of healthcare professionals as reliable information sources. Participation rates are highly influenced by their capacity to instruct patients through the decision-making process, explain the benefits and drawbacks of clinical trials, and communicate clearly. It makes one think about how important it is for people and medical experts to intersect in order to shape the narrative surrounding clinical trials. The related studies highlight how crucial it is to address moral issues, promote openness, and increase public confidence. It emphasizes the need for researchers and medical personnel to maintain the highest standards in order to protect participants' well-being and the delicate ethical balance that exists in clinical research. In conclusion, this chapter highlights the complex interactions among variables that affect clinical trial participation and the necessity of a comprehensive strategy. It serves as a catalyst for a call to action for ongoing initiatives to raise public awareness, resolve issues, and guarantee moral behavior in clinical research. A future where clinical trials significantly contribute to improved healthcare outcomes will be 27 shaped by our collective dedication to transparency, education, and empathy as we navigate the always shifting field of medical discoveries. 28
