Primary | Proportion of Patients Meeting the Criterion for Loss of Therapeutic Response (LTR) by the End of the Study (Based on Observed Cases) | Loss of Therapeutic response is defined as a worsening (increase) of at least 10 points in Social Responsiveness Scale (SRS) total raw score relative to the Visit 1 (randomization) score. The Social Responsiveness Scale (SRS) is a 65-item informant-rated assessment with total raw score ranging from 0 (no impairment) to 195 (severe social impairment). Each item is associated with 1 of 5 subscales (social awareness, social cognition, social communication, social motivation and autistic mannerisms). Each item is rated on a 4-point scale from 1 (not true) to 4 (almost always true). The scores are then transposed to a scale from 0 to 3 and scores are summed within each of the 5 subscales. A higher score indicates greater severity of social impairment. | Baseline (Visit 1) to week 12 | |
Secondary | Time to First Loss of Therapeutic (LTR) Response | Time to the first visit when a patient shows LTR following randomization to memantine or placebo. | Baseline to week 12 | |
