Detailed Description
This clinical study was a 48-week, multicenter, multinational, open-label extension study in pediatric outpatients with autism, Asperger's Disorder, or PDD-NOS conducted at 106 study centers. Patients were eligible for this long-term extension study if they had:
- completed the open-label Study MEM MD 67,or
- completed the open-label Study MEM-MD-91, or
- completed the double-blind Study MEM-MD-68, or
- discontinued study MEM-MD-68 by meeting requirements for loss of therapeutic response
The weight-based dose limits in this study were as follows:
Group A: ≥ 60 kg; maximum 15 mg/day Group B: 40-59 kg; maximum 9 mg/day Group C: 20-39 kg; maximum 6 mg/day Group D: < 20 kg; maximum 3 mg/day
The decision to close the study early was based on data from 2 double-blind placebo-controlled studies (MEM-MD-57A and MEM-MD-68) that failed to demonstrate a statistically significant difference between memantine and placebo in the primary efficacy parameter based on Social Responsiveness Scale (SRS) total raw score.

Ages Eligible for Study
Accepts Healthy Volunteers
Genders Eligible for Study
Description
Inclusion Criteria:
- Patients who completed Study MEM-MD-67, MEM-MD-68, MEM-MD-91, or discontinued Study MEM-MD-68 due to meeting the criterion for loss of therapeutic response.
- Having normal results from a physical examination and laboratory tests at Visit 1 of this study (last visit of the preceding study). Any abnormal findings must be deemed not clinically significant by the Investigator and documented as such.
- Have a family that is sufficiently organized and stable to guarantee adequate safety monitoring and continuous attendance to clinic visits for the duration of the study
Exclusion Criteria:
- Patients who discontinued a preceding memantine study due to an adverse event possibly related to study drug
- Patients with a concurrent medical condition that might interfere with the conduct of the study, confound interpretation of the study results, or endanger the patient's well being
- Significant risk of suicidality based on the Investigator's judgment, Aberrant Behavior Checklist-irritability subscale (ABC-I), or if appropriate, as indicated by a response of "yes" to questions 4 or 5 in the suicidal ideation section of the Children's Columbia-Suicide Severity Rating Scale (C-SSRS) or any suicidal behavior

Intervention / Treatment |
---|---|
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. |
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.
