Description of intervention(s) / exposure
Treatment: Drugs - Memantine Hydrochloride (HCl)

Experimental: Memantine - To maintain the blind of the preceding study, patients who participated in MEM-MD-68 (NCT01592747) began this study with 6 weeks of double blind dosing during which all patients were either titrated to or remained on their maximum target dosages. This was followed by up-to 42 weeks of open-label dosing.

Patients who took open-label memantine in study MEM-MD-67 (NCT01999894) or MEM-MD-91(NCT01592786), received up to 48 weeks of open-label memantine at their maximum tolerated weight based target dosage.


Treatment: Drugs: Memantine Hydrochloride (HCl)
During the 6-week double-blind dosing titration/maintenance period, Memantine extended-release 3-mg and 6-mg capsules; oral administration. Dosing was once daily.

During open-label treatment: Memantine extended-release 3mg capsules; oral administration. The maximum target dosage was identified during the prior studies for each patient. Dosing was once daily.
