About Daiichi Sankyo\'s Trial Portfolio
Daiichi Sankyo is an industry sponsor — typically a pharmaceutical, biotechnology, or medical device company. Industry sponsors fund and run the largest share of registered trials in the United States and are subject to FDA registration requirements under the FDA Amendments Act (FDAAA 801) for most drug and device studies.
4 of Daiichi Sankyo's 4 registered trials are currently recruiting — roughly 100% of the portfolio. A high recruiting share usually points to an active research pipeline with multiple programs at the enrollment stage.
Daiichi Sankyo's research footprint spans Bladder Cancer (2 trials), recurrent-or-metastatic-solid-tumors (1), and Advanced Solid Tumor (1) as the top three conditions. The full condition list, sorted by trial count, is in the sidebar.
Phase 2 is the largest single phase in Daiichi Sankyo's portfolio at 50% of registered trials. The full phase breakdown appears in the sidebar.

How to Approach a Trial Listing
Each trial card above links to a dedicated page with the official ClinicalTrials.gov data plus a plain-English translation of the eligibility criteria. We translate technical terminology (ECOG performance status, hepatic function values, exclusionary lab thresholds) into language that a patient or caregiver can understand, but the original clinical text and the live ClinicalTrials.gov record always govern any actual eligibility decision.
Before contacting a trial site, write down questions for your treating physician using the framework on our 25 Questions guide. Discuss whether the trial fits your treatment plan, what the time commitment looks like, and whether your insurance will cover the standard-of-care portions. Trials are not a substitute for a treatment plan — they are an addition that needs medical guidance to evaluate.

Verify any trial registration directly on ClinicalTrials.gov. For background on the FDA approval pathway that Phase 3 trials feed into, see the FDA drug approval process. For cancer-specific trial guidance, the National Cancer Institute publishes patient-oriented overviews. For global trial registrations beyond the U.S., the WHO ICTRP aggregates registries from around the world.
Frequently Asked Questions
How many clinical trials does Daiichi Sankyo have on ClinicalTrials.gov?
Daiichi Sankyo has 4 clinical trials registered on the federal ClinicalTrials.gov registry, of which 4 are actively recruiting participants right now. These counts come directly from the ClinicalTrials.gov API and are updated as the registry changes.
What conditions does Daiichi Sankyo study?
Daiichi Sankyo's registered trials cover 18 conditions on ClinicalTrials.gov, led by Bladder Cancer (2 trials), recurrent-or-metastatic-solid-tumors (1 trial), Advanced Solid Tumor (1 trial), Melanoma (1 trial), Head and Neck Cancer (1 trial). The complete condition list appears in the sidebar of this page; each condition links to a page listing every recruiting trial in that area, regardless of sponsor.
How do I join a Daiichi Sankyo clinical trial?
Joining a clinical trial is a medical decision that should always involve your treating physician. Each trial page on this site includes the eligibility criteria translated into plain English alongside the official clinical text, plus the contact information that the sponsor has registered with ClinicalTrials.gov. Bring the trial information to your doctor before reaching out — they can review the full inclusion and exclusion criteria against your medical history and help you decide whether to pursue screening.
What does the trial phase mean?
Phase 1 trials test safety and dosing in small groups (often 20–80 healthy volunteers or patients). Phase 2 trials evaluate efficacy and side effects in larger groups (100–300 patients with the target condition). Phase 3 trials confirm efficacy and monitor safety in the largest groups (300–3,000+ patients) and form the basis of an FDA approval submission. Phase 4 studies happen after a treatment is approved, monitoring long-term safety and effectiveness in real-world use. Some trials register without a phase — common for device, behavioral, or observational studies.
Where does this trial data come from?
All trial data is pulled directly from the ClinicalTrials.gov API v2, the official federal trial registry maintained by the National Library of Medicine at NIH. Under FDAAA 801, most U.S. drug and device trials are required to register, making ClinicalTrials.gov the most comprehensive source. Sponsors are responsible for keeping their listings current; trial status can shift between data refreshes.

this entity is one of the data points covered by this site’s U.S. clinical trials and research registries dataset. The detail above comes directly from the NIH ClinicalTrials.gov registry; the context that follows situates the headline numbers against the broader distribution across active and historical clinical trials.
Every number on this page links back to the NIH ClinicalTrials.gov registry; the methodology page describes the inputs, refresh cadence, and known limitations of the underlying data product.
Practical use of this page is in combination with the comparison and ranking pages elsewhere on the site, which surface the same data for this entity’s peers within active and historical clinical trials. A single-entity reading without peer context can be misleading when an entity is an outlier on one axis but typical on another.
