NCT07701928 Daridorexant hydrochloride Sleep Initiation and Maintenance Disorders Clinical Landscape Report 2026: Design, Endpoints, Sponsor and Readout Outlook

Move from a broad disease map to a decision-ready trial dossier. This focused report examines NCT07701928—Daridorexant for People With Insomnia and Alcohol Use Disorder Study (DIAS)—using PatSnap Clinical Trials, Drug & Asset, and Company & Deal Intelligence MCP evidence.

MCP evidence snapshot: 16 July 2026; publication date: 17 July 2026. Trial records can change after the snapshot and should be rechecked before operational decisions.

Why NCT07701928 is a hot trial to watch

Sleep Initiation and Maintenance Disorders is increasingly segmented by mechanism, biomarker, line of therapy, geography and endpoint architecture. NCT07701928 is notable because it tests Daridorexant hydrochloride in a Phase 2 design while Self-Reported Drinks Per Day and Heavy Drinking Days serves as the main decision variable. The value of this program will depend on whether the protocol converts biological rationale into a clinically interpretable and operationally credible readout.

PatSnap Clinical Trials MCP makes protocol fields machine-readable, while the companion asset and organization servers add mechanism, development-status and sponsor context.

Trial landscape snapshot

Design and endpoint interpretation

The design should be read as an evidence architecture, not just a phase label. Allocation is Randomized, masking is Quadruple, and the intervention model is Parallel Assignment. Enrollment of 205 participants across United States shapes statistical precision, execution risk and external validity. A strong readout will need to be interpreted against baseline risk, prior treatment, assessment schedule, missing-data handling and the clinical relevance of the observed effect.

• Primary: Self-Reported Drinks Per Day and Heavy Drinking Days — From enrollment to end of treatment at 12 weeks, and follow-up at 1-month, 6-months, and 1-year post treatment.
• Primary: Biochemically Verified Alcohol Use and Heavy Drinking Days — From enrollment to end of treatment at 12 weeks, and follow-up at 1-month, 6-months, and 1-year post treatment.
• Secondary: Total Sleep Time — From enrollment through end of treatment at week 12 and follow-up at the 1-month, 6-months, and 1-year post treatment.
• Secondary: Self-Reported Quality of Sleep and Daytime Function — From enrollment through end of treatment at week 12, and follow-up at the 1-month, 6-months, and 1-year post treatment.

Benchmark readouts in the surrounding field

• Long-term Safety and Efficacy of Extended-release Once-nightly Sodium Oxybate for Narcolepsy in Patients not Currently Taking an Oxybate (Phase 3): Cataplexy episodes(change from baseline) = -8.3 Point ( -12.1 to -4.6)
• 武田制药在2025年世界睡眠大会上公布针对1型发作性睡病 具有里程碑意义的Oveporexton（TAK-861）3期临床研究食欲素数据 (临床3期): ESS评分(第12周) = 85 % 达到; ESS评分(第12周) = 近85%的受试者与健康个体相当（≤10）。 % 达到
• Alkermes Presents Detailed Positive Results from Vibrance-1 Phase 2 Study of Alixorexton in Patients with Narcolepsy Type 1 at World Sleep Congress 2025 (Phase 2): MWT(MSL change, LSM diff at week 6 vs. placebo) = –0.6 minutes ; MWT(MSL change, LSM diff at week 6 vs. placebo) = 24.1 minutes

These indexed results are contextual benchmarks rather than direct head-to-head evidence. Cross-trial comparisons can be distorted by population, treatment line, endpoint definition, follow-up and analysis set. Their value is to clarify what magnitude and type of evidence the market already recognizes.

Asset and sponsor context

Drug & Asset context: Daridorexant hydrochloride (Approved; OX1R x OX2R)

Company & Deal Intelligence context: Washington State University — https://wsu.edu

The sponsor profile matters because scientific rationale alone does not determine development value. Manufacturing readiness, portfolio fit, geographic reach, partnering capacity and the ability to fund confirmatory development can decide whether a positive signal becomes a competitive asset.

White space around this program

• Sharper patient selection: prospective biomarker definitions that identify who is most likely to benefit.
• Clinically interpretable endpoints: outcomes that connect activity with function, symptoms, survival or treatment burden.
• Sequencing evidence: comparative data after the most relevant contemporary standard of care.
• Broader external validity: evidence across additional geographies, demographic groups and real-world settings.
• Operational differentiation: a development path that closes the readout gap without sacrificing safety or durability.

What to monitor next

Monitor recruitment status, enrollment changes, protocol amendments, endpoint hierarchy, primary-completion timing, first result indexing, asset ownership and sponsor partnerships. The most important inflection point is not always the headline data release; a change in endpoint, population or ownership can alter probability of success months earlier.

Bottom line

NCT07701928 is a focused lens on Sleep Initiation and Maintenance Disorders development. Its value will be determined by whether Daridorexant hydrochloride can convert the current design into evidence that is clinically meaningful, operationally credible and differentiated from existing benchmark readouts.
