Acute Pain has 15 drug candidates in active clinical development, of which 7 are in Phase III, 6 in Phase II and 2 in Phase I, according to Douglas Insights' count of 392 interventional trials registered on ClinicalTrials.gov (data as of 4 Oct 2026).
The acute pain drug pipeline is the set of medicines that sponsors are still testing in people for this condition: each candidate is counted once, at the highest phase it has reached in a running or recently completed trial. Medicines already on the market and studied only in Phase IV trials are kept out of the count.
How many acute pain drugs are in each phase of development?
Douglas Insights counts 7 acute pain candidates in Phase III, 47% of the 15 assets in development; Phase II holds 6 and Phase I holds 2.
| Phase (highest reached) | Assets | Share of pipeline |
|---|---|---|
| Phase III | 7 | 47% |
| Phase II | 6 | 40% |
| Phase I | 2 | 13% |
| Total | 15 | 100% |
Phase I/II candidates sit in the Phase I row and Phase II/III candidates in the Phase II row, so each acute pain asset appears in exactly one row. The 98 trials still recruiting or running carry 25% of the 392 registered trials in scope.
Which approved acute pain medicines are still in trials?
5 medicines already on the market are still being tested in acute pain Phase IV trials; Ketorolac has the most, with 15 registered trials.
| Medicine | Lead sponsor | Registered trials |
|---|---|---|
| Ketorolac | Novilla Pharmaceuticals | 15 |
| Suzetrigine | Vertex Pharmaceuticals Incorporated | 15 |
| Tramadol | Several sponsors | 15 |
| Naproxen | Laboratorios Liomont | 4 |
| Celecoxib | Laboratorios Silanes S.A. de C.V. | 3 |
Post-approval acute pain trials test new doses, new patient groups and head-to-head comparisons. They set the standard of care that every candidate in development will be measured against, so the paid review profiles each one.
How many acute pain trials are recruiting patients now?
49 acute pain trials are recruiting patients and 40 more have not started recruiting yet, out of 392 interventional trials in scope; together they make up 23% of the trial base.
| Registry status | Trials | Share |
|---|---|---|
| Completed | 199 | 51% |
| Status not verified | 52 | 13% |
| Recruiting | 49 | 13% |
| Not yet recruiting | 40 | 10% |
| Terminated | 24 | 6.1% |
| Withdrawn | 17 | 4.3% |
| Active, not recruiting | 6 | 1.5% |
| Enrolling by invitation | 3 | 0.8% |
| Suspended | 2 | 0.5% |
Terminated, suspended and withdrawn acute pain trials stay in the trial base so that a stalled programme is visible, but a candidate whose only trials stopped is no longer counted as in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 acute pain pipeline?
Laboratorios Silanes S.A. de C.V. leads the acute pain pipeline with 2 candidates; the top 5 sponsors hold 40% of the 15 assets, and 14 sponsors run at least one.
| Sponsor | Assets in development | Share |
|---|---|---|
| Laboratorios Silanes S.A. de C.V. | 2 | 13% |
| Tris Pharma, Inc. | 1 | 6.7% |
| AFT Pharmaceuticals, Ltd. | 1 | 6.7% |
| Grünenthal GmbH | 1 | 6.7% |
| Shanghai Yidian Pharmaceutical Technology Development Co., Ltd. | 1 | 6.7% |
Industry sponsors lead 64 of the 392 acute pain trials (16%); 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 acute pain pipeline?
Mechanism and drug-type classification for the 15 acute pain 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 acute pain trial readouts are coming next?
4 acute pain 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.
| Candidate | Sponsor | Phase | Primary completion | Registry |
|---|---|---|---|---|
| LY4515100 | Eli Lilly and Company | Phase II | Nov 2026 (estimated) | NCT07511816 |
| Cebranopadol | Tris Pharma, Inc. | Phase III | Jan 2027 (estimated) | NCT07845071 |
| Combogesic® | AFT Pharmaceuticals, Ltd. | Phase III | Mar 2027 (estimated) | NCT07225634 |
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 acute pain readouts fall in each quarter?
4 acute pain candidates in Phase II or later reach registered primary completion over the next eight quarters, with the most, 2, due in Q1 2027.
| Quarter | Phase III readouts | Phase II readouts | Total |
|---|---|---|---|
| Q4 2026 | 0 | 1 | 1 |
| Q1 2027 | 2 | 0 | 2 |
| Q2 2027 | 0 | 0 | 0 |
| Q3 2027 | 0 | 1 | 1 |
| Q4 2027 | 0 | 0 | 0 |
| Q1 2028 | 0 | 0 | 0 |
| Q2 2028 | 0 | 0 | 0 |
| Q3 2028 | 0 | 0 | 0 |
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 acute pain trials?
United States hosts the most acute pain trials, with sites in 144 of the 392 studies (37%); trials in scope run in 46 countries in all.
| Country | Trials with a site | Share of trials |
|---|---|---|
| United States | 144 | 37% |
| Turkey (Türkiye) | 23 | 5.9% |
| Egypt | 22 | 5.6% |
| China | 19 | 4.8% |
| Greece | 15 | 3.8% |
| Canada | 15 | 3.8% |
| France | 12 | 3.1% |
| Denmark | 11 | 2.8% |
A multinational acute pain 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 acute pain drugs being tested?
144 of the 392 acute pain trials (37%) have a site in the United States, 72 (18%) in Europe and 19 (4.8%) in China; 8 of the 15 candidates in development are tested in the US.
| Region | Trials with a site | Share of trials | Candidates tested | Regulator |
|---|---|---|---|---|
| United States | 144 | 37% | 8 | FDA |
| Europe (EU/EEA, UK, Switzerland) | 72 | 18% | 1 | EMA, MHRA, Swissmedic |
| China | 19 | 4.8% | 2 | NMPA |
| Japan | 1 | 0.3% | 0 | PMDA |
| Rest of world | 124 | 32% | 4 | national regulators |
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 acute pain 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 acute pain pipeline since the last update?
This is the first edition of the acute pain 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 acute pain pipeline?
Douglas Insights read 392 interventional trials registered on ClinicalTrials.gov for the conditions "Acute Pain", "acute pain" and updated since 4 Oct 2021, then grouped every drug or biologic named in them into 15 unique candidates.
- 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.
- 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.
- Its phase is the highest phase among those trials; placebo, standard-of-care and comparator arms are not candidates.
- Each figure on this page is drawn from one frozen dataset that passes ten checks before release, and the owner approves every edition.
