What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This early-phase trial is testing whether combining two experimental drugs, tarlatamab and ZL-1310, with or without the immunotherapy durvalumab, can safely shrink tumors in people with small cell lung cancer that has worsened after standard treatment. About 160 adults will take part to find the best dose and check for side effects. The goal is to see if this mix can control the disease longer than current options.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
tarlatamab (a drug) combined with ZL-1310 (another drug), with or without durvalumab (an immunotherapy)
What this could lead to
If successful, this could point toward a new combination treatment for small cell lung cancer that has stopped responding to standard chemotherapy.
What could go wrong
This is an early Phase 1 study with only 160 participants, so safety and the right dose are still being figured out. The combination may cause serious side effects or not shrink tumors as hoped.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Inclusion Criteria: * Age ≥ 18 years (or ≥ legal age within the country if it is older than 18 years) at the time of signing the informed consent. * Participants with Histologically or cytologically confirmed SCLC: * For Part 1, participants must have SCLC that has progressed or recurred following at least 1 line of platinum-based anti-cancer therapy. * For Parts 1 and 2, participants must have progressed or recurred following at least 1 line of platinum-based therapy. No prior tarlatamab is allowed in Cohort 2-1. * For Part 3, participants must have extensive-stage SCLC (ES-SCLC) with no prior systemic treatment other than 1 cycle of platinum-based chemotherapy. Note: Participants with prior treatment for limited-stage SCLC (LS-SCLC) before diagnosis of ES SCLC are permitted. * Eastern Cooperative Oncology Group (ECOG) performance status of 0-1. * At least 1 measurable lesion as defined per RECIST v1.1 within 21-day screening period, not previously irradiated. * Adequate organ function (hematological, coagulation, renal, hepatic, pulmonary, and cardiac function). Exclusion Criteria: * Symptomatic CNS metastases. Participants with treated brain metastases are eligible provided they meet the criteria specified in the protocol. * History of interstitial lung disease (ILD)/pneumonitis. * Received thoracic radiation therapy within 90 days prior to first dose of trial intervention. * Prior therapy with any delta-like ligand 3 (DLL3)-directed therapy. * Prior exposure to topoisomerase I inhibitors or antibody-drug conjugate (ADC) with topoisomerase I inhibitor payload. * Receiving strong CYP3A4 or CPY2D6 inhibitors within 14 days or 5 half-lives (whichever is longer) before the first dose of trial treatment. * Enrollment in any tarlatamab clinical trial.
