Abstract

The present invention relates to trans-N-[4-[2-[4-(2,3-dichlorophenyl)piperazin-1-yl]ethyl]cyclohexyl]-N′,N′-dimethylurea (cariprazine), its salts, close analogs, derivatives, pharmaceutical compositions, metabolites and combinations for use in the treatment of symptoms of autism spectrum disorder in general, and preferably the object of the present invention is to treat one or more symptoms of autism.Furthermore, it was also found that cariprazine, its salts, close analogs, derivatives, pharmaceutical compositions, metabolites and combinations are suitable for treatment of conditions such as Asperger's syndrome, atypical autism (otherwise known as pervasive developmental disorder not otherwise specified; PDD-NOS), Rett syndrome, childhood disintegrative disorder, attention deficit hyperactivity disorder (ADHD) and sensory integration dysfunction.

First claim

The invention claimed is:

1. A method of treating one or more symptoms of autism spectrum disorder in a subject, comprising administering trans-N-[4-[2-[4-(2,3-dichlorophenyl)piperazin-1-yl]ethyl]cyclohexyl]-N′,N′-dimethylurea and/or pharmaceutically acceptable salts thereof to the subject.

2. The method according to claim 1 wherein the one or more symptoms of autism spectrum disorder comprise socio-communicational deficits.

3. The method according to claim 1 , wherein the one or more symptoms of autism spectrum disorder comprise restricted and repetitive behaviors.

4. The method according to claim 1 , wherein the one or more symptoms of autism spectrum disorder comprise irritability.

5. The method according to claim 1 , wherein the one or more symptoms of autism spectrum disorder comprise attention deficit and hyperactivity.

6. The method according to claim 1 , wherein trans-N-[4-[2-[4-(2,3-dichlorophenyl)piperazin-1-yl]ethyl]cyclohexyl]-N′,N′-dimethylurea is in the form of trans-N-[4-[2-[4-(2,3-dichlorophenyl)piperazin-1-yl]ethyl]cyclohexyl]-N′ ,N′dimethylurea hydrochloride.

7. The method of claim 1 , wherein the transN-[4-[2-[4-(2,3-dichlorophenyl)piperazin-1-yl]ethyl]cyclohexyl]-N′,N′-dimethylurea is further formulated as a pharmaceutical composition comprising transN-[4-[2-[4-(2,3-dichlorophenyl)piperazin-1-yl]ethyl]cyclohexyl]-N′,N′-dimethylurea and/or pharmaceutically acceptable salts thereof and a pharmaceutically acceptable excipient.

8. The method of claim 1 , wherein the transN-[4-[2-[4-(2,3-dichlorophenyl)piperazin-1-yl]ethyl]cyclohexyl]-N′,N′-dimethylurea close and/or pharmaceutically acceptable salts thereof is further administered in combination with at least one adjunctive therapeutic agent.

9. The method according to claim 8 , wherein the at least one adjunctive therapeutic agent is selected from the group consisting of psychostimulants/nootropics, antipsychotics, antidepressants, anxiolytics, antihypertensives, antiepileptics, narcotics and spasmolytics.

10. A method for treating a disease or disorder selected from Asperger's syndrome, atypical autism, Rett syndrome, childhood disintegrative disorder, and sensory integration dysfunction, comprising administering to a patient in need thereof a pharmaceutically effective amount of trans-N -[4-[2-[4-(2,3-dichlorophenyl)piperazin-1-yl]ethyl]cyclohexyl]-N′,N′-dimethylurea or a pharmaceutically acceptable salt thereof.

11. The method according to claim 10 wherein said disease or disorder is Asperger's syndrome.

12. The method according to claim 10 wherein said disease or disorder is atypical autism.

13. The method according to claim 10 wherein said disease or disorder is Rett syndrome.

14. The method according to claim 10 wherein said disease or disorder is childhood disintegrative disorder.

15. The method according to claim 10 wherein said disease or disorder is sensory integration dysfunction.
