Obstructive Sleep Apnea Drug Pipeline: 18 Assets by Phase

How many obstructive sleep apnea drugs are in each phase of development?

Douglas Insights counts 13 obstructive sleep apnea candidates in Phase III, 72% of the 18 assets in development; Phase II holds 5 and Phase I holds 0.

Phase I/II candidates sit in the Phase I row and Phase II/III candidates in the Phase II row, so each obstructive sleep apnea asset appears in exactly one row. The 64 trials still recruiting or running carry 37% of the 172 registered trials in scope.

How many obstructive sleep apnea trials are recruiting patients now?

40 obstructive sleep apnea trials are recruiting patients and 16 more have not started recruiting yet, out of 172 interventional trials in scope; together they make up 33% of the trial base.

Terminated, suspended and withdrawn obstructive sleep apnea trials stay in the trial base so that a stalled programme is visible, but a candidate whose only trials stopped is no longer counted as in development.

Which companies lead the obstructive sleep apnea pipeline?

Eli Lilly and Company leads the obstructive sleep apnea pipeline with 4 candidates; the top 5 sponsors hold 50% of the 18 assets, and 14 sponsors run at least one.

Industry sponsors lead 56 of the 172 obstructive sleep apnea trials (33%); universities, hospitals and public funders lead the rest. A sponsor is credited with an asset when it is the lead sponsor on most of that asset's industry trials.

Which drug types and mechanisms dominate the obstructive sleep apnea pipeline?

Mechanism and drug-type classification for the 18 obstructive sleep apnea candidates is done by the research desk asset by asset, each with a cited source, and is published in the paid review together with the white-space map.

What obstructive sleep apnea trial readouts are coming next?

6 obstructive sleep apnea candidates in Phase II or later have a registered primary completion date in the next 12 months; the next three are below, each linked to its registry record.

Primary completion is the date a sponsor expects the last patient to finish the main measurement, so data usually follow within months. Dates marked estimated are the sponsor's own forecast on the registry and often move.

How many obstructive sleep apnea readouts fall in each quarter?

13 obstructive sleep apnea candidates in Phase II or later reach registered primary completion over the next eight quarters, with the most, 3, due in Q4 2026.

Each candidate is counted once, at its next readout. The paid catalyst calendar names every readout with its trial, sponsor and design, adds filings and regulatory decisions, and runs 24 months ahead.

Which countries host the most obstructive sleep apnea trials?

United States hosts the most obstructive sleep apnea trials, with sites in 91 of the 172 studies (53%); trials in scope run in 35 countries in all.

A multinational obstructive sleep apnea trial is counted once in every country where it has a site, so the shares add up to more than 100%. Country spread shows where sponsors are building the evidence that regulators in each market will ask for.

Where are obstructive sleep apnea drugs being tested?

91 of the 172 obstructive sleep apnea trials (53%) have a site in the United States, 28 (16%) in Europe and 23 (13%) in China; 12 of the 18 candidates in development are tested in the US.

Each region's trials are the evidence its regulator will review: the FDA in the United States, the EMA (with the MHRA and Swissmedic) in Europe, the NMPA in China and the PMDA in Japan. A multinational obstructive sleep apnea trial counts once in every region where it has a site, so the shares add up to more than 100%. A candidate tested only outside the US and Europe is often a licensing opportunity for sponsors in those markets.

What has changed in the obstructive sleep apnea pipeline since the last update?

This is the first edition of the obstructive sleep apnea pipeline count, dated 4 Oct 2026. The next refresh is due by 2 Jan 2027, and each refresh lists the assets that entered, advanced or dropped out.

How does Douglas Insights count the obstructive sleep apnea pipeline?

Douglas Insights read 172 interventional trials registered on ClinicalTrials.gov for the conditions "Sleep Apnea, Obstructive", "obstructive sleep apnea" and updated since 4 Oct 2021, then grouped every drug or biologic named in them into 18 unique candidates.

1. Code names, generic names and brand names of the same molecule are merged into one candidate, and every merge is reviewed by the research desk.
2. A candidate counts when it has a trial that is recruiting, running, or completed in the last 24 months, and at least one industry-sponsored trial.
3. Its phase is the highest phase among those trials; placebo, standard-of-care and comparator arms are not candidates.
4. Each figure on this page is drawn from one frozen dataset that passes ten checks before release, and the owner approves every edition.
