Recruiting the right patients for clinical trials is always a challenge, especially when those patients are under the radar, underdiagnosed or difficult to engage due to cultural barriers. This is especially true in therapeutic areas like women’s health and mental health, where patients may not even be aware of their diagnosis or recognize symptoms as treatable conditions.
In this webinar, the featured speakers will explore how tailored messaging, strategic platform selection and dedicated patient support can turn invisible populations into active participants across borders, protocols and patient profiles. Drawing on recent real-world evidence studies from three countries, this session will examine how cultural context, ad format and human connection influence recruitment success at scale.
Register for this webinar to learn patient recruitment strategies that blend data, design and digital outreach to reach underrepresented populations.
