Completed · Phase 2

Conditions studied: Phenylketonuria

In brief

This study is an extension of previous rAvPAL-PEG studies. Administration of rAvPAL-PEG will be continued to assess whether long-term dosing of rAvPAL-PEG is safe and can maintain reduced blood Phe concentrations in PKU subjects.

• Must have completed participation in previous rAvPAL-PEG studies.
• Willing and able to provide written, signed informed consent, or, in the case of participants under the age of 18, provide written assent (if required) and written informed consent by a parent or legal guardian, after the nature of the study has been explained, and prior to any research-related procedures.
• Willing and able to comply with all study procedures.
• Females of childbearing potential must have a negative pregnancy test at Screening and be willing to have additional pregnancy tests during the study. Females considered not of childbearing potential include those who have been in menopause at least 2 years, or had tubal ligation at least 1 year prior to Screening, or who have had total hysterectomy.
• Sexually active subjects must be willing to use an acceptable method of contraception while participating in the study.
• Maintained a stable diet.
• In generally good health as evidenced by physical examination, clinical laboratory evaluations (hematology, chemistry, and urinalysis), and electrocardiogram (ECG) at Screening.

You may not qualify if…

• Use of any investigational product (with the exception of rAvPAL-PEG) or investigational medical device within 30 days prior to Screening, or requirement for any investigational agent prior to completion of all scheduled study assessments.
• Use of any medication that is intended to treat PKU within 14 days prior to the administration of study drug.
• Use or planned use of any injectable drugs containing PEG (other than rAvPAL-PEG), including Depo-Provera during study participation.
• A prior reaction that included systemic symptoms (eg, generalized hives, respiratory or gastrointestinal problems, hypotension, angioedema, anaphylaxis) to rAvPAL-PEG or a PEG-containing product.
• Pregnant or breastfeeding at Screening or planning to become pregnant (self or partner) or to breastfeed at any time during the study.Concurrent disease or condition that would interfere with study participation or safety (eg, history or presence of clinically significant cardiovascular, pulmonary, hepatic, renal, hematologic, gastrointestinal, endocrine, immunologic, dermatologic, neurological, oncologic, or psychiatric disease).
• Any condition that, in the view of the PI, places the subject at high risk of poor treatment compliance or of not completing the study.
• Known hypersensitivity to rAvPAL-PEG or its excipients, including hypersensitivity reactions that necessitated early termination from previous rAvPAL-PEG studies.
• Alanine aminotransferase (ALT) concentration > 2 times the upper limit of normal.
• Creatinine > 1.5 times the upper limit of normal.
