What Are Externally-Led Patient-Focused Drug Development (EL-PFDD) Meetings?

Externally-Led Patient-Focused Drug Development (EL-PFDD) meetings are special gatherings created to bring the real-world experiences and voices of patients and caregivers directly to the center of decision-making about new treatments and research.

Established by the U.S. Food and Drug Administration (FDA), the Patient-Focused Drug Development (PFDD) initiative aims to ensure the concerns, needs, and priorities of people living with serious medical conditions—Maternal Alloimmunization and HDFN—are understood by FDA, product developers, clinicians, and academic researchers and used to guide the development and evaluation of new therapies.

Why Attend?

The EL-PFDD meeting is all about patient voices

This meeting is for families who have experienced maternal alloimmunization or hemolytic disease of the fetus and newborn (HDFN), including patients, parents, caregivers, and loved ones. By attending, you will hear first-hand stories from other families and have the opportunity to share your own experience.

These patient perspectives will be heard by the people shaping future research and care.

Who Should Participate?

This meeting is designed for anyone with lived experience of maternal alloimmunization or HDFN.

Participants may include:

Patients currently navigating maternal alloimmunization
Parents of babies affected by HDFN
Families who have experienced fetal loss or complications
Caregivers and loved ones who supported someone through this diagnosis

Every story helps create a clearer picture of what families experience.

Who Will Be Listening?

The experiences shared during the meeting will help inform leaders working to improve care and develop future therapies.

Stakeholders may include:

The U.S. Food and Drug Administration (FDA)
Researchers studying maternal alloimmunization and HDFN
Clinicians who care for high-risk pregnancies and newborns
Pharmaceutical and biotechnology companies
Patient advocacy organizations

Why Your Voice Matters

Maternal alloimmunization and HDFN are rare and often misunderstood conditions.

By sharing your experience, you can help:

Highlight challenges families face during pregnancy and after birth
Identify gaps in current care and treatment options
Guide future research priorities
Improve awareness among clinicians and researchers

Patient experiences are essential to shaping better care and future therapies.

Topic 1: Health Effects and Daily Impacts of Maternal
Alloimmunization and HDFN

  1. Of all the symptoms, experiences, and challenges related to maternal
    alloimmunization and HDFN, which 1–3 had the most significant impact on your
    life, pregnancy, or family?
  2. Are there specific activities or parts of pregnancy, birth, or early parenthood that
    you could not experience as fully as you would have liked because of
    alloimmunization or HDFN?
  3. As it relates to your experience with alloimmunization and HDFN, what did a good
    day look like? What did a difficult day look like?
  4. How have your condition, care experience, and its impact changed over time, during
    one pregnancy or across multiple pregnancies?
  5. What worried you most during your pregnancy and your baby’s care journey?

Topic 2: Current Approaches to Treatment and Care

  1. What types of monitoring, treatments, or interventions did you receive during
    pregnancy and after birth to help manage alloimmunization and HDFN?
  2. How did your treatment regimen or care plan change over time, and why?
  1. How well did your monitoring and treatments address the most significant
    challenges you faced or improve your pregnancy and your baby’s outcomes?
  2. What were the most significant downsides or burdens associated with your care and
    treatments?
  3. Short of a complete cure, what would an ideal treatment or approach to managing
    alloimmunization and HDFN look like?
