  • inclusion criteria:
  • 1. Informed consent and assent (if necessary, at the investigator*s discretion
  • [ie, for children]) with parental/legal guardian consent
  • 2. Male or female subjects of any age.
  • 3. Clinical diagnosis of PKU with hyperphenylalaninemia (HPA) documented by
  • past medical history of at least 2 blood Phe measurements >=600 µmol/L
  • 4. Women of childbearing potential, as defined in (CTFG 2020), must have a
  • pregnancy test at study entry and agree to abstinence or the use of at least
  • effective form of contraception (with a failure rate of <1% per year when used
  • consistently and correctly):
  • Combined (estrogen- and progestogen-containing) hormonal contraception
  • associated with inhibition of ovulation:
  • * Intravaginal
  • * Transdermal
  • Progestogen-only hormonal contraception associated with inhibition of ovulation:
  • * Injectable
  • * Implantable
  • Intrauterine device
  • Intrauterine hormone-releasing system
  • Bilateral tubal occlusion
  • Vasectomized partner with confirmed azoospermia
  • Highly effective contraception or abstinence must be continued for the duration
  • study and for up to 90 days after the last dose of the study drug.
  • All females will be considered of childbearing potential unless they are
  • postmenopausal (at least 12 months consecutive amenorrhea in the appropriate
  • age group without other known or suspected cause) or have been permanently
  • sterilized surgically (eg, hysterectomy, bilateral salpingectomy, bilateral
  • oophorectomy).
  • 5. Males who are sexually active with women of childbearing potential who have
  • not had a vasectomy must agree to use a barrier method of birth control during
  • the study and
  • for up to 90 days after the last dose of study drug. Males must also refrain
  • donations during this time period.
  • Males who are abstinent will not be required to use a contraceptive method
  • unless they become sexually active. Males who have undergone a vasectomy are
  • not required to use a contraceptive method if at least 16 weeks post procedure.
  • 6. Willing and able to comply with the protocol and study procedures
  • 7. Willing to continue current diet unchanged while participating in the study
  • (unless specifically instructed to change diet during the study by the
  • investigator)

排除标准

  • Individuals are not eligible to participate if they meet any of the following
  • exclusion criteria:
  • 1. The individual, in the opinion of the investigator, is unwilling or unable
  • to adhere to
  • the requirements of the study
  • 2. Inability to tolerate oral medication
  • 3. A female who is pregnant or breastfeeding, or considering pregnancy
  • 4. Serious neuropsychiatric illness (eg, major depression) not currently under
  • control, that in the opinion of the investigator or sponsor, would interfere
  • subject*s ability to participate in the study or increase the risk of
  • participation for that
  • 5. Past medical history and/or evidence of renal impairment and/or condition
  • moderate/severe renal insufficiency (glomerular filtration rate [GFR] <60
  • estimated most recently during qualifying participation in a feeder study)
  • and/or under
  • care of a nephrologist
  • 6. Any other condition that in the opinion of the investigator or sponsor,
  • would interfere
  • with the subject*s ability to participate in the study or increase the risk of
  • participation
  • for that subject
  • 7. Requirement for concomitant treatment with any drug known to inhibit folate
  • (eg, methotrexate)
  • 8. Concomitant treatment with BH4 supplementation (eg, sapropterin
  • dihydrochloride,
  • KUVAN) or pegvaliase-pqpz (PALYNZIQ)
  • Additional criteria for subjects who did not participate in a feeder study:
  • 9. Gastrointestinal disease (such as irritable bowel syndrome, inflammatory
  • bowel disease, chronic gastritis, and peptic ulcer disease, etc) that could
  • affect the absorption of study drug
  • 10. History of gastric surgery, including Roux-en-Y gastric bypass surgery or
  • an antrectomy with vagotomy, or gastrectomy
  • 11. History of allergies or adverse reactions to synthetic BH4 or sepiapterin
  • 12. Current participation in any other investigational drug study or use of any
  • investigational agent within 30 days prior to Screening
  • 13. Any clinically significant laboratory abnormality as determined by the
  • investigator. In general, each laboratory value from Screening and baseline
  • chemistry and hematology panels should fall within the limits of the normal
  • laboratory reference range, unless deemed not clinically significant by the
  • investigator
  • 14. Any abnormal physical examination and/or laboratory findings indicative of
  • signs or symptoms of renal disease, including calculated GFR <60 mL/min/1.73 m2.
  • In subjects >=18 years of age, the Modification of Diet in Renal Disease
  • Equation should be used to determine GFR.
  • In subjects <18 years of age, the Bedside Schwartz Equation should be used to
  • determine GFR.
  • 15. Confirmed diagnosis of a primary BH4 deficiency as evidenced by biallelic
  • pathogenic mutations in 6-pyruvoyltetrahydropterin synthase, recessive GTP
  • cyclohydrolase I, sepiapterin reductase, quinoid dihydropteridine reductase, or
  • pterin-4-alpha-carbinolamine dehydratase genes
