Homovanillic Acid: A 3-O-methyl ETHER of (3,4-dihydroxyphenyl)acetic acid.
homovanillate : A hydroxy monocarboxylic acid anion which is obtained by deprotonation of the carboxy group of homovanillic acid.
homovanillic acid : A monocarboxylic acid that is the 3-O-methyl ether of (3,4-dihydroxyphenyl)acetic acid. It is a catecholamine metabolite.
Vomiting: The forcible expulsion of the contents of the STOMACH through the MOUTH.

| "Although the neurotransmitter basis of chemotherapy-induced vomiting (CIV) is thought to be multifactorial, it is generally accepted that acute (immediate) CIV is mainly due to the release of serotonin (5-HT) within the gastrointestinal tract, while the delayed phase occurs following substance P (SP) release in the brainstem." | 3.75 | A re-evaluation of the neurotransmitter basis of chemotherapy-induced immediate and delayed vomiting: evidence from the least shrew. ( Abad, J; Crim, JL; Darmani, NA; Janoyan, JJ; Ramirez, J, 2009) |
| " However, in contrast to D2-selective antagonists, SCH39166 failed to increase plasma prolactin levels, did not block apomorphine-induced emesis in the dog and had minimal effects on the striatal levels of homovanillic acid or dihydroxyphenylacetic acid." | 3.67 | Pharmacological profile of SCH39166: a dopamine D1 selective benzonaphthazepine with potential antipsychotic activity.

The Yale Global Tic Severity Score is a composite of subject reported severity of motor (range 0-25) and vocal (range 0-25) tics , as well as an impairment score (range 0-50). The outcome we are using is the Total Tic Severity score which is the sum of the motor and vocal tic severity scores (range 0-50). The higher the score on this scale, the more severe the symptoms. A positive drug effect is associated with a decrease from baseline. (NCT01244633)
Timeframe: 8 weeks
| Intervention | units on a scale (Mean) |

Change in the self-injurious subscale of the Behavior Problems Inventory (BPI). the BPI is a well-validate test to evaluate the frequency and severity of a patient's self-injurious behavior. Values range from 0 to 50, and a low score means few/less severe behaviors (NCT01065558)
Timeframe: Screening visit and end of study (two weeks)
| Intervention | Change in BPI score (Mean) |

This study's primary outcome is the safety of ecopipam in Lesch-Nyhan patients as measured by standard clinical laboratory tests. The patients will also be observed and questioned about other side effects, such as whether they feel more or less tired.Standard clinical laboratory tests for liver, kidney and blood function were conducted. The normal ranges for each of these tests were different and are too numerous to be individually listed here. However, if any individual value were to be either three-times greater or lesser than the upper or the lower limit of the test, then that value was considered to have been changed. (NCT01065558)
