Tarlatamab is named as a drug or biological intervention in 14 clinical trials in our USA, China, UK and Ireland trial registers, 5 of which are recruiting. Lead sponsors include Amgen (13) and GlaxoSmithKline (1). Registered phases: Phase 1, Phase 3 and Phase 2. Conditions studied include Small Cell Lung Cancer; Extensive Stage Small Cell Lung Cancer; Small Cell Lung Cancer (SCLC).
Registers list studies that are recruiting, about to open, active but closed to enrolment, or enrolling by invitation. The UK and USA registers cover industry-sponsored studies only. Trial titles and statuses are copied from the registry as published.

Everything on this page is copied from public ClinicalTrials.gov registry records — it is not written from memory, and nothing here describes how Tarlatamab works or whether it is effective. Each trial links to its own record so you can check it yourself.
This page is built automatically: a daily sync job reads the registry records behind our country trial registers, collects every trial that lists Tarlatamab (or a registered synonym) as a drug or biological intervention, and tabulates the registry fields directly. Placebos and generic comparators are excluded. There is no AI drafting and no per-compound editorial pass, and the page has not been clinically reviewed. The “last verified” date above is the timestamp of that sync, not a review date. Our general editorial approach is described in our editorial standards and corrections policy. The ClinicalTrials.gov data on this page was last retrieved on 24 Sep 2026.
