According to the results reported on ClinicalTrials.gov, this trial involved 425 people with epilepsy who were taking lacosamide (a seizure medication). Participants were split into two groups: 106 people received 300 mg per day and 319 people received 400 mg per day. The trial was measuring whether lacosamide could be used on its own (as a "monotherapy") rather than alongside other epilepsy medicines — specifically, it tracked how many participants hit certain warning signs (called "exit criteria") within 112 days, such as a significant increase in seizure frequency or a new type of seizure occurring. The reported data shows that for the primary outcome — the percentage of people in the 400 mg group who reached at least one of those warning signs by Day 112 — the figure was 30.0%. The result for the 300 mg group was not reported for this measure. For a broader secondary measure that also counted people who stopped due to side effects or lack of benefit, the reported figure for the 400 mg group was 32.3%. When looking at how long it took participants to first hit a warning sign, the reported median time was 39 days in the 300 mg group and 45 days in the 400 mg group. Both groups spent a reported median of 71 days on lacosamide as the only medication during the monotherapy phase of the study. The reported data also shows how doctors and patients rated overall change compared to the start of the trial. In the 400 mg group, doctors rated 56 participants as "very much improved" and 116 as "much improved," while patients in that group rated 81 as "very much improved" and 93 as "much improved." Smaller numbers in both groups were rated as minimally or much worse. These are the results as reported to ClinicalTrials.gov.
