Brief Summary:
This is a Phase 4 observational study designed to assess the impact of Palynziq ® (pegvaliase) treatment in pregnant women with PKU and on their offspring who were exposed to pegvaliase at any time during pregnancy and breastfeeding.

Condition or disease Intervention/treatment
Phenylketonuria, Maternal Drug: Pegvaliase

Detailed Description:
Women prescribed pegvaliase by their healthcare provider (HCP) who become pregnant during treatment may decide to participate in the study and enroll via a centralized call center model. Upon consent, data will be collected from the patient's HCP(s) retrospectively for at least 3 months prior to Last Menstrual Period (LMP). Data will be collected during pregnancy and throughout the infant's first year of life. Pegvaliase exposure will be recorded during pregnancy and breastfeeding including exposure during each trimester of pregnancy. Duration of individual subject participation will be up to approximately 21 months.

 Drug: Pegvaliase
Pregnant women exposed to pegvaliase within 2 weeks prior to LMP.


Outcome Measures

Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Pregnancy outcome and infant development for women who have been treated with Palynziq (pegvaliase) within 2 weeks of their last menstrual period [ Time Frame: 10 years ]
    To estimate the frequency of pregnancy outcomes (eg, spontaneous abortion, stillbirth, live birth, and termination) among subjects with PKU treated with pegvaliase during pregnancy and fetal/infant outcomes (all major congenital malformations [MCMs] and specifically microcephaly and congenital heart defects], FGR, small for gestational age [SGA], low birth weight, preterm birth, failure to thrive, and developmental delays) among their offspring exposed to pegvaliase during pregnancy.


Secondary Outcome Measures :
  1. Pregnancy Outcomes [ Time Frame: 10 years ]
    To compare the frequency of pregnancy outcomes (eg, spontaneous abortion, stillbirth, live birth, and termination) and fetal/infant outcomes (all MCMs and specifically microcephaly and congenital heart defects, FGR, SGA, low birth weight, preterm birth, failure to thrive, and developmental delays) among subjects with PKU treated with pegvaliase during pregnancy and their offspring to information on those same outcomes in non-pegvaliase exposed, pregnant women with PKU as described in reference literature

  2. Pregnancy Outcomes [ Time Frame: 10 years ]
    To examine differences in the frequency of pregnancy outcomes (eg, spontaneous abortion, stillbirth, live birth, and termination) and fetal/infant outcomes (all MCMs and specifically microcephaly and congenital heart defects, FGR, SGA, low birth weight, preterm birth, failure to thrive, and developmental delays) among subjects with PKU treated with pegvaliase during pregnancy and their offspring by maternal blood Phe levels

  3. Serious Adverse Events [ Time Frame: 10 years ]
    To estimate the frequency of serious adverse events (SAEs) other than CMs in infants exposed to pegvaliase during pregnancy through their first year of life

  4. Maternal Pegvaliase use during breastfeeding [ Time Frame: 10 years ]
    To estimate the frequency of selected outcomes in subjects with PKU treated with pegvaliase during breastfeeding (low milk supply) and their infants (failure to thrive and SAEs) through their first year of life

Criteria

Inclusion Criteria:

  • Subject (or a legally authorized representative) consent obtained prior to enrollment. Consent will be obtained in compliance with any country-specific regulations or requirements
  • Confirmation of ongoing pregnancy. Subjects with unknown outcomes will be classified as prospective pregnancies; subjects who have undergone prenatal testing (eg, targeted ultrasound, amniocentesis) regardless of findings will be classified as retrospective pregnancies
  • Diagnosed with PKU per local standard of care
  • Documentation that the subject was treated with pegvaliase at any point starting from 2 weeks prior to the date of LMP
  • Agrees to permit the Investigator (ie, CRP, CCA, PI) to contact the subject's HCPs (eg, PCP, PKU-treating physician, OB, nurse, midwife) and the infant's HCP (eg, pediatrician, neonatologist) for medical information

Exclusion Criteria:

• Currently participating in a BioMarin sponsored interventional study of any investigational product, device, or procedure
