DETECTNET (copper Cu 64 dotatate)
dɪˈtektˌnet
RadioMedix, Inc.
Approval date: September 3, 2020


DRUG TRIALS SNAPSHOT SUMMARY:

What is the drug for?

DETECTNET is a drug for detection of the specific type of tumors called somatostatin receptor positive neuro-endocrine tumors (NETs) in adults.

NETs are rare tumors that develop in certain hormone-producing cells of the body’s neuro-endocrine system.

How is this drug used?

DETECTNET is injected into a vein in preparation for an imaging test (called positron emission tomography scan or PET scan) to help detect the tumor.

What are the benefits of this drug?

Were there any differences in how well the drug worked in clinical trials among sex, race and age?

  • Sex: DETECTNET worked similarly in men and women.
  • Race: The majority of patients were White. The number of patients of other races were limited; therefore, differences in how the drug worked among races could not be determined.
  • Age: DETECTNET worked similarly in patients younger and older than 60 years of age.

What are the possible side effects?

DETECTNET is a radioactive drug which may increase the risk of lifetime radiation exposure.

The most common side effects of DETECTNET are nausea, vomiting, and flushing.

Were there any differences in side effects among sex, race and age?

Because the side effects were rare, it was not possible to determine the differences in side effects among sex, race and age.

WHO WAS IN THE CLINICAL TRIALS?

Who participated in the trials?

The FDA approved DETECTNET based on data from two trials that evaluated 175 adult patients.

Trial 1 evaluated adult patients, some of whom had known or suspected NETs and some of whom were healthy volunteers. The trial was conducted at one site in the United States (Houston, TX).

Trial 2 data came from the literature-reported trial of 112 adult patients, all of whom had history of NETs. The trial was conducted at one site in Denmark.

The figure below summarizes how many men and women were in the clinical trials.

How were the trials designed?

For DETECTNET approval, the FDA evaluated the data from two trials.

In Trial 1, some patients had NETs, and some did not. Both groups received DETECTNET and underwent PET scan imaging.

In Trial 2, all patients had history of NETs and underwent PET scan imaging with DETECTNET.

In both trials, DETECTNET images were compared to either biopsy results or other images taken by different techniques to detect the sites of a tumor. The images were read as either positive or negative for presence of NETs by three independent image readers who did not know patient clinical information.

GLOSSARY

CLINICAL TRIAL: Voluntary research studies conducted in people and designed to answer specific questions about the safety or effectiveness of drugs, vaccines, other therapies, or new ways of using existing treatments.
COMPARATOR: A previously available treatment or placebo used in clinical trials that is compared to the actual drug being tested.
EFFICACY: How well the drug achieves the desired response when it is taken as described in a controlled clinical setting, such as during a clinical trial.
PLACEBO: An inactive substance or “sugar pill” that looks the same as, and is given the same way as, an active drug or treatment being tested. The effects of the active drug or treatment are compared to the effects of the placebo.
SUBGROUP: A subset of the population studied in a clinical trial. Demographic subsets include sex, race, and age groups.
