Limitations and Caveats

Hide Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
The two high dose groups of ELND005 were discontinued before study end, so the efficacy analysis was based only on placebo and ELND005 250 mg bid groups.
