Clinical Trial Awareness, Perceptions, and Participation Among Cancer Patients in Saudi Arabia

Background: Clinical trials are essential tools for advancing cancer treatment, improving survival rates, and introducing innovative therapies. However, patient participation in clinical trials remains low in the Middle East, including Saudi Arabia. This study explores Saudi cancer patients' awareness, perceptions, and willingness to participate in clinical trials while identifying key barriers to enrollment. Methods: A cross-sectional survey was conducted using a self-administered questionnaire distributed via email and social media. Saudi cancer patients aged 14 and older, fluent in Arabic or English, and with a confirmed cancer diagnosis were eligible. Ethical approval was obtained, and participation was voluntary with ensured data confidentiality. The survey assessed awareness of clinical trials, perceived benefits, willingness to enroll, and barriers to participation. Data were analyzed using SPSS version 23, with chi-square tests used to examine associations. Results: A total of 201 participants completed the survey. Most were female (69.2%), with a mean age of 39.5 years. Awareness of clinical trials was moderate (51.2%), with social media and healthcare providers being primary information sources. While 57.2% recognized the benefits of clinical trials, 44.8% expressed concerns about risks. Trust in healthcare providers influenced willingness to participate, with 49.8% confident in their physician's recommendations. The most common barriers were fear of side effects (82.6%) and lack of information (42.8%). Only 5.5% had prior experience with clinical trials, but 35.3% expressed willingness to enroll if recommended by a healthcare provider. Gender and income were significantly associated with perceptions and willingness to participate. Conclusions: Findings highlight the need for targeted educational initiatives to improve awareness and trust in clinical trials among Saudi cancer patients. Addressing key barriers, particularly concerns about side effects and limited information, could enhance participation, ultimately advancing cancer research and treatment in the region.
