Plain English summary of protocol

Background and study aims
Hemolytic disease of the newborn and fetus (HDFN) is a rare and potentially life-threatening blood disorder in newborn babies and fetuses that occurs when the blood types of the pregnant individual and fetus/baby are incompatible, thus resulting in fast breakdown of red blood cells (RBCs) of the fetus/baby. This may lead to anemia (low hemoglobin levels), jaundice (yellow discoloration of the skin because of the high levels of the chemical, bilirubin in blood) and other related complications.

Currently, severe HDFN is most commonly treated by injecting donor red blood cells into the fetus, a procedure called intrauterine transfusion. Nipocalimab, the study drug in this trial, is a protein that targets and binds to a specific molecule called FcRn (neonatal fragment crystallizable receptor). These receptors are found throughout the body and also in the placenta.
In pregnant individuals at risk for severe HDFN, nipocalimab aims to decrease the level of IgG (immunoglobulin G) antibodies* targeting fetal RBCs by binding to the FcRn receptor thereby decreasing IgG levels in the pregnant individual pregnant individuals IgG antibodies to the fetus across the placenta. Nipocalimab may be a less invasive option for managing severe HDFN.
*one type of protein that protects the body from infections caused by bacteria, viruses, and other foreign substances in the blood.

The purpose of the study is to assess the safety and effectiveness of nipocalimab compared to placebo (a drug like substance that has no therapeutic effect) in the treatment of pregnant individuals at risk of developing severe HDFN.

Not everyone in the study will receive nipocalimab. For every two participants who receive nipocalimab, one participant receives placebo. This is a double-blind study, which means that the participant and the study doctor/team will not know whether if you are receiving nipocalimab or placebo.

Who can participate?
This study will include pregnant individuals from 18 to 45 years old, with a gestational age of (GA) Week 13 to 18 weeks at the start of study treatment, and who have a history of severe hemolytic disease of the fetus and newborn (HDFN) in a prior pregnancy.

What does the study involve?
The study consists of 4 periods:
- Screening period (up to 11 weeks): Pregnant individuals will be evaluated from gestational age (GA) Week 8 through GA Week 18 to confirm they can take part in the study. During this period, a test will be done to determine if the fetus is reactive to the pregnant individual’s antibodies.
- Treatment period: Participants will be randomly (like a flip of coin) assigned to receive either nipocalimab or placebo in 2:1 ratio, which means for every 2 participants who receive nipocalimab, 1 participant receives placebo. Participants will be dosed intravenously on a weekly basis for up to 23 weeks, after which they will continue to have weekly visits until delivery (up to 3 weeks)
- Safety follow-up period up to 6 months for pregnant individual after delivery and up to 2years for the neonate/infant after birth.
Participants will undergo study assessments and tests, such as blood tests, vaginal tests, ultrasound (imaging test that uses sound waves to produce images within the body), questionnaires and other assessments for fetal monitoring. Newborns may receive light-therapy or may be transfused with donor blood to manage high bilirubin level. Blood samples will be taken at multiple timepoints throughout the study. The possible side effects of the study drug will be documented and monitored during the study.
The overall duration of the study will be up to 2 years and 6 months.

What are the possible benefits and risks of participating?
There is no established benefit to participants of this study. Based on scientific theory, taking nipocalimab may reduce the risk and severity of HDFN. However, this cannot be guaranteed because nipocalimab is still under investigation as a treatment.
If participants are assigned to the placebo group, they will not receive nipocalimab during this study.

Currently, severe HDFN is most commonly treated by injecting donor red blood cells into the fetus, a procedure called intrauterine transfusion. The study doctor will determine the need for an intrauterine transfusion, no matter if you are receiving nipocalimab or placebo.

Participants may experience some benefit from participation in the study that is not due to the study drug. However, they may benefit from regular medical visits and assessments which will monitor overall health of participants.

Participants may have side effects and risks related to nipocalimab or procedures used in this study. Some of them may be serious and may require treatment and/or additional testing. Problems that are not expected may arise and they may be life-threatening.

Based on the limited experience in healthy individuals and patients and our current understanding of how nipocalimab might work in the body, there are several types of side effects that might occur in people receiving nipocalimab. Potential risks in participants include infection, reduced effectiveness of routine vaccines, and activation of latent virus due to decreased serum IgG (a type of blood protein that protects the body from infections such as bacteria and viruses, and allergens) concentrations. Additionally, there are potential risks of lowering of albumin in blood, infusion reactions, interactions with other therapeutic drugs, increase in cholesterol levels and placental infarction (disruption of blood supply to a part of the placenta). There is a potential risk for low IgG in neonates/infants born to mothers who received nipocalimab during pregnancy.

The participant information sheet and informed consent form, which will be signed by each participant who agrees to join the study, includes a detailed section outlining the known risks of participating in the study.

Not all possible side effects and risks related to nipocalimab are known at this moment. During the study, the sponsor may learn new information about nipocalimab. The study doctor will tell participants as soon as possible about any new information that might make them change their mind about being in the study, such as new risks.

To minimize the risk associated with taking part in the study, participants are frequently asked about any side effects and other medical events they experience. Participants are instructed to report any such events to the study doctor who will provide appropriate medical care. Any serious side effects that are reported to the sponsor are thoroughly reviewed by a specialist drug safety team.

There are no costs to participants to be in the study. The sponsor will pay for the study drug, tests and procedures that are part of the study. The participant will receive reasonable reimbursement for study-related costs (e.g., travel/parking costs).

Where is the study run from?
Janssen-Cilag International NV is the sponsor for this study. The study will be run at multiple healthcare locations both within the UK and around the world.

When is the study starting and how long is it expected to run for?

34. Bayley Scales of Infant Development and Toddler Development. The Bayley Scales of infant development is considered the standard assessment of early child development and includes cognition, language, motor skills, social emotional, and adaptive behaviour will be reported. The Bayley Scales (3rd edition) are reference standards that measure infant and toddler development in five areas: cognition, language, motor skills, social-emotional and adaptive behaviour. The cognition, language and motor skills scales are directly administered to the infant, while social-emotional, and adaptive behaviour scales are caregiver questionnaires. The scores are standardized using norm reference samples with representative demographics and age adjusted for prematurity. Higher scores in the Bayley Scales indicate better outcomes.
35. Change From Baseline in Generalized Anxiety Disorder 7-Item (GAD7) Over time During Pregnancy and Postpartum. The GAD-7 scale is a self-administered questionnaire designed to measure anxiety. The recall period for all items is the past 2 weeks. Responses to all items are rated on a 4-point Likert scale ranging from 0 “not at all” to 3 “nearly every day”. The total score ranges from 0 to 21, with higher scores indicating higher severity of anxiety symptoms.
36. Change From Baseline in Short Form 36 Version 2 (SF-36v2) Acute Form Domain Score. The SF-36 version 2 acute is a self-administered, 36-item questionnaire measuring health-related quality of life and includes 8 domains that measure physical functioning, role limitations due to physical health problems, bodily pain, general health, vitality social functioning, role limitations due to emotional problems, and mental health. The 8 domains can be aggregated into 2 summary scales that reflect physical and mental health: a physical component summary and a mental component summary. Responses to all items are rated on a 3, 5, or 6-point Likert scale, with higher scores indicating better health status.
37. Change From Baseline in EuroQol Five-dimension Questionnaire (EQ-5D-5L) Visual Analogue Scale (VAS) Score. The EQ-5D descriptive system is comprised of 5 items across the following 5 dimensions: mobility, self-care, usual activities, pain or discomfort and anxiety or depression. The EQ-5D-5L uses a 5-point Likert response scale ranging from “no problems” to “extreme problems”, with higher scores indicating better quality of life. EQ-5D-5L consists of the EQ-5D descriptive system and the EQ visual analogue scale (EQ-VAS). EQ-VAS score ranges from 0 to 100, where 0 = worst imaginable health state and 100 = best imaginable health state. Higher score indicates good health state.
38. Change From Baseline in EuroQol 5-Dimension Descriptive (EQ-5D) Index Score. The EQ-5D descriptive system is comprised of 5 items across the following 5 dimensions: mobility, self-care, usual activities, pain or discomfort and anxiety or depression. The EQ 5D-5L descriptive system uses a 5-point Likert response scale ranging from “no problems” to “extreme problems”, with higher scores indicating better quality of life.
39. Infant Health-Related Quality of Life Instrument (IQI) Score for Neonate or Infant Overtime. The IQI consists of 7 health attributes including sleeping, feeding, breathing, stooling or poo, mood, skin, and interaction. Responses to all items are rated on a 4-point Likert scale, with higher scores indicating better quality of life.
