Using matching-adjusted indirect comparison (yeah I have no idea what this means either), we compared efficacy outcomes in patients with relapsing-remitting multiple sclerosis treated with delayed-release dimethyl fumarate (DMF) or glatiramer acetate (GA).
MATERIALS & METHODS:An indirect comparison of DMF (patient-level data) and GA (aggregate data) was conducted, with average baseline characteristics of DMF patients weighted to match those for GA patients. Direct comparison of DMF and GA was conducted in CONFIRM. Final results pooled the indirect and direct comparisons using meta-analysis.
RESULTS:After matching, baseline characteristics were balanced between DMF and GA patients. Compared with GA, efficacy was significantly in favor of DMF as measured by annualized relapse rate (rate ratio: 0.76; 95% CI: 0.57-1.00; p = 0.0474) and 12-week confirmed disability progression (risk ratio: 0.59; 95% CI: 0.46-0.76; p < 0.0001).
CONCLUSION:DMF demonstrated superior clinical efficacy versus GA.
So if it is worse how come its numero uno on the sales front?.
So one guesses that side-effect profile is perceieved as the important factor and not whether it works or not.
The alternative view is the laggard lazy neurologist, who figures no monitoring requirements for a while until one finds that it don’t work very well for most people.
I know that some people think it is the best thing since sliced bread:-)
