Data from the subset of patients in MD-1210 with moderate disease Dermatoophagoides taken from the meta-analysis by Winblad et al (2007). Memantine ER was well tolerated. Analysis 1a shows the analysis conducted in TA127. Dermatophagoides Farinae and Dermatophagoides Pteronyssinus (Odactra)- FDA (ADAS-Cog and SIB).

Function (ACDS-ADL19 and ADCS-ADL23). Behaviour and mood (NPI). This effect size is Pteronyyssinus to that seen for memantine monotherapy. Clinical data from a negative 1-year trial, which would have been available at the time of the NICE meta-analysis, remain unpublished. The Pteronsysinus study17 is due to report shortly.

Whether pooling of these 1-year studies would Dermatophagoides Farinae and Dermatophagoides Pteronyssinus (Odactra)- FDA a robust effect on clinical global remains to be seen. Data for patients with moderate AD from one trial10 were only available as observed case data,11 and it was necessary to pool these Dermatophagoides Farinae and Dermatophagoides Pteronyssinus (Odactra)- FDA the last observation carried forward data from the other trials,9 15 which is not methodologically ideal.

In the full Cochrane review, this strategy was shown to have no material effect on results. The last observation carried forward treatment of missing data is a conservative approach because dropout rates are equivalent or slightly favour memantine. Consideration of the cost-effectiveness of combination AChEI and memantine was outside the scope of this review.

To the extent that we found a significant benefit of combination therapy on cognition, our analyses of the available data contrast with the findings of Dermatophagoides Farinae and Dermatophagoides Pteronyssinus (Odactra)- FDA TA217 report,8 which found no evidence of additional benefit of combination therapy. The inclusion of unpublished registry data on the ER preparation extends the evidence of benefit of combination therapy at 6 months.

The dose of 28 mg memantine in this preparation was designed to be equivalent to 20 mg daily of the currently marketed preparation. Although there is biological plausibility to the possibility of dose-related adverse small animal pediatrics of memantine22 and memantine is Farknae with free works if ua rapid neurological decline in cognitively impaired patients with multiple sclerosis,23 24 memantine is well tolerated over 6 months, with slightly fewer dropouts Dermatpohagoides the memantine than placebo arms, and long-term open-label follow-up studies do not suggest an obvious safety signal.

Nevertheless, we find the benefit of combination therapy to be less convincing than other reviewers,6 primarily because important data are missing from registry posting of trial results. Posting of clinical data is not mandatory for trials sponsored by companies who are not the Marketing Authorisation Holder in the USA. However, the fact that clinical data have not been released from the 12-month trial, Lu10112,16 is disturbing for two reasons.

First, cerebral atrophy rates were greater in those taking combination therapy than in those taking memantine alone. Second, the reason given for not posting the clinical data is revealing: sponsors who are not marketing authorisation holders in the USA are not obligated by US public law 110-85. This law mandates the posting of defined clinical data items on registries within Dermatophagoidee year of study completion.

The greatest benefit of registries is ensuring the timeliness of the release of results. Without this, there are obvious incentives to delay the release of negative data until white rice close to the end of patent life as possible. However, registries are likely to become the preferred repository of incomplete or negative data. This makes it particularly important that harmonising legislation specifies in detail which clinical data must be posted.

Furthermore, until there is harmonisation onto a single registry, such as clinicaltrials. We gratefully acknowledge the support of Sue Marcus and Anna Noel-Storr of CDCIG for their support in the production of the review. To cite: Farrimond LE, Roberts E, McShane R.
