Ortho-McNeil Neurologics modified the PRECAUTIONS section of the Prescribing Information for Reminyl, approved only for the treatment of mild to moderate Alzheimer's Disease.

The changes provide new safety information regarding the results of two randomized, placebo-controlled trials of 2 years duration in subjects with mild cognitive impairment(MCI). A total of 13 subjects on REMINYL (n=1026) and 1 subject on placebo (n=1022) died.

The deaths were due to various causes which could be expected in an elderly population. About half of the REMINYL deaths appeared to result from various vascular causes (myocardial infarction, stroke), and sudden death.

March 31, 2005

Dear Healthcare Professional:

The REMINYL� (galantamine hydrobromide) Prescribing Information has been updated with the addition of the following information regarding the results of two investigational studies of REMINYL in individuals with mild cognitive impairment.

REMINYL is approved only for the treatment of mild to moderate Alzheimer�s Disease. No indication is being sought for the treatment of individuals with mild cognitive impairment.

PRECAUTION

Deaths in Subjects with Mild Cognitive Impairment (MCI)

In two randomized, placebo-controlled trials of 2 years duration in subjects with mild cognitive impairment (MCI), a total of 13 subjects on REMINYL� (n=1026) and 1 subject on placebo (n=1022) died. The deaths were due to various causes which could be expected in an elderly population; about half of the REMINYL� deaths appeared to result from various vascular causes (myocardial infarction, stroke, and sudden death).

Although the difference in mortality between REMINYL� and placebo-treated groups in these two studies was significant, the results are highly discrepant with other studies of REMINYL�.

Specifically, in these two MCI studies, the mortality rate in the placebo-treated subjects was markedly lower than the rate in placebo-treated patients in trials of REMINYL� in Alzheimer�s disease or other dementias (0.7 per 1000 person years compared to 22-61 per 1000 person years, respectively).

Although the mortality rate in the REMINYL�-treated MCI subjects was also lower than that observed in REMINYL�- treated patients in Alzheimer�s disease and other dementia trials (10.2 per 1000 person years compared to 23-31 per 1000 person years, respectively), the relative difference was much less.

When the Alzheimer�s disease and other dementia studies were pooled (n=6000), the mortality rate in the placebo group numerically exceeded that in the REMINYL� group. Furthermore, in the MCI studies, no subjects in the placebo group died after 6 months, a highly unexpected finding in this population.

Individuals with mild cognitive impairment demonstrate isolated memory impairment greater than expected for their age and education, but do not meet current diagnostic criteria for Alzheimer�s disease.
