Study summary

The objective of this study is to assess two novel positron emission tomography (PET) radiotracers, [64Cu]CM500 and [68Ga]CM500, for Positron Emission Tomography-Magnetic Resonance Imaging (PET-MR) and Positron Emission Tomography / Computed Tomography (PET-CT) imaging of solid tumors. These tracers have the potential to detect solid tumors throughout the body and may enable doctors to identify smaller tumors than conventional imaging techniques.

Read the detailed description

The primary objectives of this study are:

  1. To evaluate the safety of [64Cu]CM500 and [68Ga]CM500 and their whole-body distribution, metabolism, pharmacokinetics, and radiation burden in healthy volunteers.
  2. To measure the distribution of [64Cu]CM500 and [68Ga]CM500 PET in patients with different types of cancer.

Exclusion criteria

Exclusion Criteria:

  • Less than 18 years of age;
  • Electrical implants such as cardiac pacemaker or perfusion pumps (MR-PET only);
  • Pregnant or breastfeeding (a negative STAT quantitative serum or urinary hCG pregnancy test is required for females having before the subject can participate);

  • Unable to lie comfortably on a bed inside a PET scanner;
  • Body weight over the weight limit for the moving table (> 300 lbs for the MRI table and >441 lbs for the CT table);

Terms in these criteria, in plain language(10)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

COPD

Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

QT and QTc

On an ECG, the QT interval is the time the heart’s lower chambers take to activate electrically and recover in each beat. QTc is that time adjusted for heart rate (QTcF by Fridericia’s formula, QTcB by Bazett’s). Some medicines lengthen it, and a long QTc can raise the risk of a dangerous heart rhythm.

The study may name a correction formula and a limit in milliseconds, often around 450–480.

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Sep 2026; primary completion for Sep 2027, 12 months later.

Of 80 industry-sponsored phase 1 interventional studies under Urinary Bladder Neoplasms, half reached primary completion within 43 months of starting (the median), counting those still running; a quarter within 30 and three quarters within 66. This study's planned 12 months is below that.

Counting every sponsor, half of 145 studies reached it within 43 months; a quarter within 29 and three quarters within 66.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 28, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
