Before you decide if you should participate in a clinical study, you should understand exactly what to expect and what will be expected of you. You may want to talk with your doctor about clinical studies in general or about a specific study. The doctor working on a clinical study will discuss all aspects of the study with you, and you will have the opportunity to ask as many questions as you want. As a starting point, the following questions and answers may help you understand some of the basics about clinical studies.
Underlined terms can be clicked for definition.
Clinical studies help determine if study drugs, treatments, or devices are safe and if they produce the desired results for treating, preventing, or diagnosing a disease or other health condition. Regulatory authorities, like the Food & Drug Administration (FDA), require that clinical studies be done before a drug or device is approved and made available to the general public.
Federal law requires most health insurance plans to cover routine patient care costs in clinical studies under certain conditions, provided that:
You, your doctor, or a member of the clinical study team should check with your health plan to find out which costs it will cover.
Clinical studies follow a specific set of standards and are closely regulated to help protect study participants. An Independent Ethics Committee (IEC) or Institutional Review Board (IRB) reviews and monitors each study closely to safeguard the rights and welfare of participants. Any known risks and side effects will be discussed during the informed consent process, but there may be unknown risks. It is important to understand that the investigational study drug being tested may not work for you, and that your condition or health could remain the same, improve, or get worse.
The use of placebo in oncology clinical studies is now very rare. Many studies compare the investigational study drug against the standard of care treatment for the disease to tell which one is better and safer for patients.
In the studies referenced on this website, there is no placebo group, and all study participants will receive the investigational study drug, tarlatamab, by infusion in a vein. The dosage and timing of infusions may vary depending on the rules of the study.
Clinical studies are done in different steps, or phases.
Clinical studies rely on the participation of patient volunteers. If you decide to participate in a clinical study, you will be asked to:
Remember that you may ask questions at any time and should expect a prompt answer from the study staff.
Activities can vary from visit to visit and may include the following:
If you choose to participate in a clinical study, you are encouraged to communicate freely with the study doctor and staff throughout the study. If you have questions or concerns about any aspect of the study, you should feel comfortable discussing them with the study doctor at any time.
Yes, you may leave a clinical study at any time because participation is voluntary. If you choose to participate, you will need to follow instructions and complete study-related activities BUT you may stop at any time for any reason.
Yes, you can. You can visit any doctor necessary to meet your health needs during a study. You should tell other healthcare professionals you see that you are participating in a clinical study and always communicate openly with the study doctor regarding other care you receive.
There are two main types of lung cancer: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). SCLC makes up about 15% of lung cancer cases.
SCLC is a fast-growing cancer that develops when a specific type of lung cell, called a neuroendocrine cell, grows out of control.
SCLC is usually diagnosed based on the results of a tumor biopsy.
Your primary source of information about your health, or any health condition or diagnosis, should always be your doctor or another healthcare professional.
NEPC is an aggressive type of cancer that develops in the prostate gland. Diagnosis of NEPC is usually based on a biopsy of the cancer. Biopsies are often performed in metastatic castrate-resistant prostate cancer (mCRPC) patients with aggressive disease and/or disease progression with low or non-rising PSA levels.
NEPC can sometimes be diagnosed from a blood sample by looking for genetic changes in the DNA from the cancer1.
Your primary source of information about your health, or any health condition or diagnosis, should always be your doctor or another healthcare professional.

What is the
DeLLphi-304 study?
DeLLphi-304 is a clinical study comparing tarlatamab with standard of care chemotherapy in patients whose cancer has returned after first-line treatment.
What is the
DeLLpro-300 study?
DeLLpro-300 is a clinical study that is testing an investigational drug called tarlatamab. The study is being done to see how safe and effective tarlatamab is at treating patients with neuroendocrine prostate cancer (NEPC) that has spread to another site in the body after one previous treatment.
