|---|---|---|---|
| Primary | Proportion of Patients Entrained as Assessed by Urinary aMT6 | 1 month | Entrainment is a measure of synchronization of the master body clock to the 24-hour day. The circadian period (τ) was calculated using urinary aMT6s collected over four 48 hour periods , collected approximately 1 week apart for 4 separate weeks, during the screening and month 1 of the randomization phase of the trial. Entrainment was defined as having a post-baseline τ value less than 24.1 and a 95% CI that included 24.0. |
| Primary | Proportion of Patients With a Clinical Response: Entrainment of aMT6 and Score of ≥ 3 on N24CRS | 6 months | Clinical response is defined as the coincident demonstration of entrainment (aMT6) and a score ≥ 3 on the Non-24 Clinical Response Scale (N24CRS). N24CRS measures improvement in sleep-wake measures and overall functioning (LQ-nTST, UQ-dTSD, MoST and CGI-C). Each assessment is scored as a 1 or 0 depending on the pre-specified threshold (see below). LQ-nTST: \>45 minutes increase in average nighttime sleep duration; UQ-dTSD: \>45 minutes decrease in average daytime sleep duration; MoST: \>30 minutes increase and a standard deviation \<2 hours during double-masked phase (6 months); CGI-C: \<2.0 from the average of D112 and Day 183 compared to baseline For patients randomized to tasimelteon 20 mg and who also participated in the screening phase of Study 3203 (month 7 of treatment), the screening τ from Study 3203 was used if the patient did not become entrained in Study 3201 but did become entrained during the screening phase of Study 3203. |
| Secondary | Proportion of Patients Entrained as Assessed by Urinary Cortisol | 1 month | Entrainment is a measure of synchronization of the master body clock to the 24-hour day. The circadian period (τ) was calculated using urinary cortisol collected over four 48 hour periods, approximately 1 week apart for 4 separate weeks, during the screening and month 1 of the randomization phase of the trial. Entrainment was defined as having a post-baseline τ value less than 24.1 and a 95% CI that included 24.0. |
| Secondary | Average Clinical Global Impression of Change (CGI-C) | Day 112 and 183 | CGI-C scores range from 1 (very much improved) to 7 (very much worse). The average post-randomization score was obtained for each patient by averaging the last 2 scheduled assessments (Day D112 and Day D183). Lower number indicates improvement. |
| Secondary | Proportion of Responders With a Combined Sleep/Wake Response for LQ-nTST (≥ 90 Minutes) and UQ-dTSD (≤ 90 Minutes) | 6 months | The sleep/wake response represents measurement of the combined improvement in the nighttime sleep duration and daytime sleep duration. Individuals that have an improvement in nighttime sleep and daytime sleep, defined as an increase of 90 minutes or more in the lower quartile of subjective nighttime total sleep time (LQ-nTST) and a decrease of 90 minutes or more in the upper quartile of daytime total sleep duration (UQ-dTSD) are considered to be a responder. |
| Secondary | Average Lower Quartile of Nights of Nighttime Total Sleep Time (LQ-nTST) | 6 months | LQ-nTST measures the difference in average nighttime sleep during the patient's worst 25% of nights (shortest total nighttime sleep) between the randomized phase (6 months)and the screening phase (\~ 6 weeks). The higher number indicates improvement. |
| Secondary | Average Upper Quartile of Days of Subjective Daytime Sleep Duration (UQ-dTSD) | 6 months | UQ-dTSD measures the difference in average daytime sleep during the patient's worst 25% of days (longest total daytime sleep) between the randomized phase (6 months) and the screening phase (\~ 6 weeks). Lower number indicates improvement. |
| Secondary | Average Midpoint of Sleep (MoST) | 6 months | Midpoint of Sleep Timing (MoST) is the measurement of the average midpoint of sleep time relative to bedtime. The average MoST value will trend to 0 as an individual's sleep becomes more fragmented. Improvement is defined as an increase in the average. |
| Secondary | Number of Patients With a Treatment Emergent Adverse Event (Open Label Extension Phase Only) | 6 months | Adverse events were recorded in the source documents from the time of the patient's informed consent signature until the end of the patient's study participation. An AE was defined as any untoward medical occurrence in a clinical investigation patient who does not necessarily have causal relationship with treatment. |
| Other | Proportion of Patients With a Clinical Response: Entrainment of aMT6 and Score of ≥ 2 on N24CRS | 6 months | Clinical response is defined as the coincident demonstration of entrainment (aMT6) and a score ≥ 2 on the Non-24 Clinical Response Scale (N24CRS) which includes LQ-nTST, UQ-dTSD, MoST and CGI-C assessments. Each assessment is scored as a 1 or 0 depending on the pre-specified threshold (see below). LQ-nTST: \>45 minutes increase in average nighttime sleep duration; UQ-dTSD: \>45 minutes decrease in average daytime sleep duration; MoST: \>30 minutes increase and a standard deviation \<2 hours during double-masked phase (6 months); CGI-C: \<2.0 from the average of D112 and Day 183 compared to baseline For patients randomized to tasimelteon 20 mg and who also participated in the screening phase of Study 3203 (month 7 of treatment), the screening τ from Study 3203 was used if the patient did not become entrained in Study 3201 but did become entrained during the screening phase of Study 3203. |
| Other | Proportion of Patients With a Clinical Response (Score of ≥ 3 on N24CRS) | 6 months | Non-24 Clinical Response Scale (N24CRS) was a 4-item scale which includes LQ-nTST, UQ-dTSD, MoST and CGI-C assessments. Each assessment is scored as a 1 or 0 depending on the pre-specified threshold (see below). LQ-nTST: \>45 minutes increase in average nighttime sleep duration; UQ-dTSD: \>45 minutes decrease in average daytime sleep duration; MoST: \>30 minutes increase and a standard deviation \<2 hours during double-masked phase (6 months); CGI-C: \<2.0 from the average of D112 and Day 183 compared to baseline |
