E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the efficacy of ecopipam to reduce self-injurious behaviors (SIB) in adults and children with Lesch-Nyhan Disease (LND) in an outpatient setting. |
|

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Subjects must have classic LND as defined by (a) characteristic clinical syndrome (evidence of overproduction of uric acid, severe generalized dystonia, frequent and persistent SIB, and cognitive impairment) and (b) laboratory confirmation for mutation of the HPRT gene or severe deficiency of the associated enzyme.
2. Subjects must have a minimum combined score of 20 on the BPI SIB subscales for frequency and severity as assessed by the caregiver.
3. Subjects must have a minimum score of 4 on the Physician?s Global Impression (PGI) severity scale.
4. Subjects must be ?6 years old.
5. Subject must have a body weight greater than 10 kg.
6. Although females with LND are extremely rare, they are occasionally encountered. For a woman to be eligible she must be postmenopausal (>12 months without menses) or surgically sterile (ie, by hysterectomy and/or bilateral oophorectomy) or must be using effective contraception (ie, oral contraceptives, intrauterine device, double barrier method of condom and spermicide) and agree to continue use of contraception for the duration of their participation in the study. Women of childbearing potential must agree to use contraception for 30 days after their last dose of study drug.
7. Sexually active male subjects must use a barrier method of contraception during the study and agree to continue the use of male contraception for at least 30 days after the last dose of study drug.
8. Subject and/or legal guardian must execute a written Informed Consent and/or Assent. |

3. Subjects who are currently treated with medications for seizures
4. Subjects with impaired renal function as defined by a serum creatinine >1.5 mg/dL.

6. Women of childbearing potential who are currently pregnant or lactating. |
