Subcutaneous Tarlatamab in Participants with Advanced Stage Small Cell Lung Cancer (DeLLphi-308)
Summary description of the study
This is an early clinical study to understand how participants tolerate and respond to different doses of SC Tarlatamab. This study is being conducted at multiple hospitals and is an open-label study, meaning both the researchers and participants know which treatment is being administered. Participants in this study suffer from advanced SCLC, which has either recurred or continued to grow after at least one prior SCLC treatment. The researchers' goal is to understand whether SC Tarlatamab is safe and well-tolerated, how the body responds to it, whether it can trigger the development of antibodies (an immune response), and slow cancer growth. The study includes three main phases: screening, treatment, and follow-up. During the follow-up, participants will no longer receive SC Tarlatamab but will undergo a safety check, followed by a long-term observation period. Participants will be included either in Part 1, where different doses of SC Tarlatamab are tested, or in Part 2, where the dose chosen in Part 1 is further investigated. A maximum of 100 participants can participate in both parts of the study (up to 60 participants in Part 1 and 40 participants in Part 2).

Intervention under investigation
Tarlatamab is a special protein that binds to specific target cells and prompts the immune system to kill cancer cells. The subcutaneous injections in Part 1 are administered in the abdomen, and in Part 2 either in the abdomen or in the thigh.
In both parts, participants are monitored in the hospital for 24 hours after the first two SC Tarlatamab injections. After the third SC Tarlatamab injection, participants will be observed for a period of 6 to 8 hours, and after the fourth and fifth SC Tarlatamab injections for a period of 6 hours.

Disease under investigation
Small Cell Lung Cancer (SCLC) is a type of cancer that originates in the lung. Small Cell Lung Cancer can grow very rapidly, and there is a high risk that it will spread to other parts of the body. Researchers are investigating a drug called Tarlatamab, which is administered to participants with SCLC who have already been treated for SCLC, via an injection just under the skin (subcutaneous; SC). Tarlatamab targets a protein found in SCLC called delta-like ligand 3 (DLL3).
(BASEC)
The study will include men and women aged 18 years and older who have been diagnosed with advanced SCLC that has either recurred or continued to grow after at least one prior treatment. Participants must have adequate organ function and be in physical condition to tolerate the treatment. Participants must be able to receive subcutaneous injections of Tarlatamab in their abdomen or thigh, depending on which part of the study they are included in. Additional inclusion criteria apply according to the study protocol. (BASEC)
Exclusion criteria
Participants must not have received prior DLL3-targeted treatment and must not have untreated or symptomatic SCLC that has spread to the brain. Pregnant women, breastfeeding women, or women planning a pregnancy are not allowed to participate in the study. Participants must not receive any other investigational drugs. Additional exclusion criteria apply according to the study protocol. (BASEC)
