Pneumococcal Disease Drug Pipeline: 20 Assets by Phase

How many pneumococcal disease drugs are in each phase of development?

Douglas Insights counts 7 pneumococcal disease candidates in Phase III, 35% of the 20 assets in development; Phase II holds 4 and Phase I holds 9.

Phase I/II candidates sit in the Phase I row and Phase II/III candidates in the Phase II row, so each pneumococcal disease asset appears in exactly one row. The 31 trials still recruiting or running carry 22% of the 141 registered trials in scope.

Which approved pneumococcal disease medicines are still in trials?

1 medicines already on the market are still being tested in pneumococcal disease Phase IV trials; V114 has the most, with 21 registered trials.

Post-approval pneumococcal disease 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 pneumococcal disease trials are recruiting patients now?

17 pneumococcal disease trials are recruiting patients and 3 more have not started recruiting yet, out of 141 interventional trials in scope; together they make up 14% of the trial base.

Terminated, suspended and withdrawn pneumococcal disease trials stay in the trial base so that a stalled programme is visible, but a candidate whose only trials stopped is no longer counted as in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 pneumococcal disease pipeline?

CanSino Biologics Inc. leads the pneumococcal disease pipeline with 4 candidates; the top 5 sponsors hold 65% of the 20 assets, and 12 sponsors run at least one.

Industry sponsors lead 109 of the 141 pneumococcal disease trials (77%); 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 pneumococcal disease pipeline?

Mechanism and drug-type classification for the 20 pneumococcal disease 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 pneumococcal disease trial readouts are coming next?

5 pneumococcal disease 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 pneumococcal disease readouts fall in each quarter?

5 pneumococcal disease candidates in Phase II or later reach registered primary completion over the next eight quarters, with the most, 2, 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 pneumococcal disease trials?

United States hosts the most pneumococcal disease trials, with sites in 51 of the 141 studies (36%); trials in scope run in 51 countries in all.

A multinational pneumococcal disease 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 pneumococcal disease drugs being tested?

51 of the 141 pneumococcal disease trials (36%) have a site in the United States, 37 (26%) in Europe and 31 (22%) in China; 10 of the 20 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 pneumococcal disease 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 pneumococcal disease pipeline since the last update?

This is the first edition of the pneumococcal disease pipeline count, dated 3 Oct 2026. The next refresh is due by 1 Jan 2027, and each refresh lists the assets that entered, advanced or dropped out.

How does Douglas Insights count the pneumococcal disease pipeline?

Douglas Insights read 141 interventional trials registered on ClinicalTrials.gov for the conditions "Pneumococcal Infections", "Streptococcus pneumoniae infection" and updated since 3 Oct 2021, then grouped every drug or biologic named in them into 20 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.
