Synced daily from ClinicalTrials.gov via AACT. Last sync: .

32 Tarlatamab clinical trials are catalogued on Hipa.ai from the AACT mirror of ClinicalTrials.gov, spanning 24 indications (including Small Cell Lung Cancer & Extensive Stage Small Cell Lung Cancer) and 4,380 total planned enrollment. 5 Phase 3 Tarlatamab trials and 15 Phase 2 are listed. 19 Tarlatamab clinical trials are actively recruiting at 84 U.S. sites across 28 states. Most recent activity: NCT06898957 (Jun 2031).

Where to Participate: All Tarlatamab Trial Sites in the U.S. (84 sites across 28 states)

Every actively recruiting Tarlatamabtrial site, sorted by state then city. Each row links to the trial detail page (eligibility, contacts, full study record). Sites no longer enrolling at the location level are excluded. ClinicalTrials.gov / AACT does not provide street-level addresses; the map link uses the facility's geocoded coordinates where available.
