However, recent pharmacokinetic studies demonstrate that DHE metabolites measured in humans are too low to have substantial clinical effect and probably do not contribute to sustained efficacy.
In addition, sustained efficacy over multiple doses has not yet been demonstrated.
In MTX-inadequate responders with RA, abatacept provided consistent safety and sustained efficacy over 3 years.
However, evidence of its adverse events and sustained efficacy is lacking.
Again, this probably reflects the ability of SM-11355 to exhibit sustained efficacy.
In PATENT-2, riociguat showed sustained efficacy and tolerability in patients with PAH-CHD at 2 years.
Patient retention was high in the RAPID 2 OLE, which indicates an acceptable tolerability profile and sustained efficacy of CZP.
4– 7 Experience with intravenous abatacept has demonstrated consistent safety and sustained efficacy, and a low immunogenicity rate that has no significant impact on pharmacokinetics, safety and efficacy.
Finally, physicians wish there was an insulin treatment that would have sustained efficacy if patients miss a dose or, to extrapolate, delay a dose.
Many participants in the Osteoporosis Study participated in a 2 year extension study in which bazedoxifene showed sustained efficacy in preventing fractures over 5 years of therapy.
However, the utility of antisense-miRNAs in therapeutic intervention is largely dependent on effective delivery and sustained efficacy of the internalized antisense-miRNAs following treatment.
