|---|---|
| Experimental: Strengths of solriamfetol (JZP-110) strengths: 37.5 mg，75 mg, 150 mg subject will first enter a 2-week Titration Phase, during which the initial dose will be 37.5mg. The dose will be increased from 37.5mg QD to 75mg QD after 3 days, and then to 150mg QD at the first day of the second week if well-tolerated. subjects will then enter the 10-week Maintenance Phase on 150mg QD if well-tolerated. If a subject tolerability issues after titration up to 150mg at the second week, the dose can be reduced to 75mg QD following instructions of the investigators. This subject will then enter the 10-week Maintenance Phase on 75mg QD. If a subject experiences tolerability issues after titration up to 75mg at the first week, the dose can be reduced to 37.5mg QD following instructions of the investigators. The dose will be increased to 75mg QD again at the first day of the second week. Subject will then enter the 10-week Maintenance Phase on 75mg QD if well-tolerated. All subjects should be maintained on either 75mg QD or 150mg QD during the Maintenance Phase. |

Outcome Measures
Primary Outcome Measures
- To compare the change from baseline in MWT(Maintenance of Wakefulness Test ) (minutes) (determined from the mean of the first four 40-minute MWTs) at the end of the 12-week treatment with solriamfetol versus placebo [From enrollment to the end of treatment at 12 weeks]
Change from baseline in MWT (minutes) (determined from the mean of the first four 40-minute MWTs) at the end of the 12-week treatment
- To compare the change from baseline in ESS value at the end of the 12-week treatment with solriamfetol versus placebo in adult OSA patients with EDS [From enrollment to the end of treatment at 12 weeks]
Change from baseline in ESS value at the end of the 12-week treatment
Secondary Outcome Measures
- Key Secondary Study Objective: To compare the percentage of subjects with (minor, significant, or extreme) improvement in PGIc at the end of the 12-week treatment with solriamfetol versus placebo in adult OSA patients with EDS [From enrollment to the end of treatment at 12 weeks]
Percentage of subjects with improved PGIc at the end of 12-week treatment

• Changes from baseline in MWT at the end of the 2- and 5-week treatment are defined as: mean sleep latency at the end of the 2- and 5-week treatment (determined from the mean of the first four 40-minute MWTs) minus the baseline measurement (minutes)

• The percentages of subjects with (minor, significant, or very significant) improvement in PGIc at the end of the 2-, 5-, and 8-week treatment are defined as the percentages calculated by dividing the number of subjects who have achieved a (minor, significant, or very significant) improvement in PGIc at the end of the 2-, 5-, and 8-week treatment by the total number of subjects in each treatment group
- Other Secondary Study Objective 4: To compare the percentage of subjects with (minor, significant, or very significant) improvement in the (CGIc) at the end of the 12-week treatment with solriamfetol versus placebo in adult OSA patients with EDS [From enrollment to the end of treatment at 12 weeks]
• The percentage of subjects with (minor, significant, or very significant) improvement in CGIc at the end of the 12-week treatment is defined as the percentage calculated by dividing the number of subjects who have achieve a(minor, significant, or very significant) improvement in CGIc at the end of the 12-week treatment by the total number of subjects in each treatment group
- the percentages of subjects with (minor, significant, or very significant) improvement in Clinical Global Impression of Change (CGIc) at the end of the 2-, 5-, and 8-week treatment with solriamfetol versus placebo in adult OSA patients with EDS [From enrollment to the end of treatment at the 2- ,5- and 8-week]
The percentages of subjects with (minor, significant, or very significant) improvement in CGIc at the end of the 2-, 5-, and 8-week treatment are defined as the percentages calculated by dividing the number of subjects who have achieve a(minor, significant, or very significant) improvement in CGIc at the end of the 2-, 5-, and 8-week treatment by the total number of subjects in each treatment group
- the time course of the efficacy of MWT after treatment with solriamfetol versus placebo in adult OSA patients with EDS [From enrollment to the end of treatment at 12 weeks]
Changes of the efficacy in MWT over time after treatment: changes in time to sleep onset per test for 5 MWTs (minutes)
