- Have received documented approval from a study dietician confirming that the subject is capable of maintaining their diet in accordance with dietary information presented in the protocol.
- Have neurocognitive and linguistic capacities to comprehend and answer investigator's prompts for the ADHD RS- Investigator rated instrument and to complete the POMS-Subject rated scale.
- If applicable, maintained stable dose of medication for attention deficit hyperactivity disorder (ADHD), depression, anxiety, or other psychiatric disorder for ≥8 weeks prior to enrollment and willing to maintain stable dose throughout study unless a change is medically indicated.
- Are in generally good health, as evidenced by physical examination, clinical laboratory evaluations and ECG tests performed at screening
- EXCLUSION CRITERIA
- Individuals who meet any of the following exclusion criteria will not be eligible to participate in the study:
- Use of any investigational product 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 (except Kuvan), including the use of large neutral amino acids, within 2 days prior to administration of study drug Day 1 (first dose of BMN 165). Note: Kuvan treatment must be stopped ≥14 days before Day 1
- Use or planned use of any injectable drugs containing PEG (other than BMN 165), including medroxyprogesterone injection, within 3 months prior to screening and during study participation
- Known hypersensitivity to any components of BMN 165
- Current use of levodopa
- A positive test for HIV antibody, hepatitis B surface antigen, or hepatitis C antibody
- A history of organ transplantation or on chronic immunosuppressive therapy
- A history of substance abuse (as defined by the Diagnostic and Statistical Manual of Mental Disorders \[DSM IV\]) in the past 12 months or current alcohol or drug abuse
