Trial Summary

What is the purpose of this trial?

18F-sodium fluoride (18F-NaF) was already investigated numerous times in the last 40 years as a PET alternative to standard 99m-technetium-derived bone scintigraphy. However, lack of universal tracer availability and higher costs contributed to the failure of 18F-NaF to systematically supplant bone scintigraphy as a standard of care. Recently, an isotope shortage crisis occurred and evidenced the need to have non-reactor-derived alternatives for many nuclear medicine procedures, including bone scintigraphy. Since 18F-NaF is cyclotron-produced, it could become a necessary alternative to bone scintigraphy in case of another worldwide isotope shortage. The study aims to evaluate the safety profile of 18F-NaF injection. Moreover, a patient registry will be compiled in order to perform sub-studies on 18F-NaF diagnostic performance on diverse bone and articular diseases.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the drug 18F-sodium fluoride for bone cancer?

Research shows that 18F-sodium fluoride, when used in PET/CT scans, is highly effective in detecting bone metastases, which are cancerous growths that spread to the bones. This drug provides clearer and more accurate images compared to older methods, helping doctors make better treatment decisions for patients with bone cancer. ^{1 2 3 4 5}

Is 18F-NaF PET imaging safe for humans?

18F-NaF PET imaging has been used for many years and is considered safe for humans. It was approved by the U.S. Food and Drug Administration in 1972 and is known for its rapid clearance from the blood and high uptake in bones, which makes it effective for imaging without significant safety concerns. ^{1 2 3 6 7}

How is the drug 18F-NaF different from other treatments for bone cancer?

18F-NaF PET/CT is unique because it offers higher sensitivity and specificity in detecting bone metastases compared to traditional bone scans, and it provides rapid imaging with better patient convenience. This drug is a positron-emitting agent that allows for high-quality imaging of the skeleton, making it particularly effective for assessing both malignant and benign bone diseases. ^{1 2 3 6 8}

Eligibility Criteria

This trial is for patients who need a bone scan (99mTc-biphosphonate bone scintigraphy) due to conditions like infections, arthritis, or bone tumors. It includes adults and children with cancer or infectious diseases needing this test. Pregnant individuals, those allergic to 18F-NaF, or unable to lie flat for at least 15 minutes cannot participate.

Inclusion Criteria

I can lie on my back comfortably.

I am a child needing a bone scan for cancer or infection.

Patients for whom a 99mTc-biphosphonate bone scintigraphy is indicated

Exclusion Criteria

Known allergy or hypersensitivity to 18F-NaF or any of its constituants.

I cannot lie on my back for more than 15 minutes.

Treatment Details

Interventions

• 18F-sodium fluoride (Radiopharmaceutical)

Trial Overview The study tests the safety and effectiveness of using an imaging agent called 18F-sodium fluoride (18F-NaF) in PET scans as an alternative to standard bone scintigraphy. This could be important if there's another shortage of the usual radioactive material used in these scans.

Participant Groups

Group I: 18F-NaF eligible patients Experimental Treatment 1 Intervention

Eligibility for 18F-NaF PET scans is the same than for bone scintigraphy routinely prescribed in the clinic.

Findings from Research

Sodium fluoride labeled with fluorine 18 (18F-NaF) is a highly effective radiopharmaceutical for skeletal imaging, particularly in detecting bone metastases from cancers like breast and prostate, showing increased sensitivity and specificity compared to traditional imaging methods.

The recent advancements in PET/CT technology have revitalized the clinical use of 18F-NaF, making it a valuable tool for oncologists in accurately assessing skeletal disease due to its favorable pharmacokinetics and superior imaging capabilities.

In a study involving 2,217 cancer patients aged 65 and older, (18)F-sodium fluoride PET (NaF PET) significantly influenced treatment decisions, with a 40% overall change in management based on scan results.

For patients showing new or progressive osseous metastasis, 59% of treating physicians planned to switch therapies, which increased to 76% when the estimated prognosis worsened, highlighting NaF PET's critical role in monitoring treatment response.

Sodium fluoride labeled with 18F (NaF) PET/CT is a valuable imaging tool for accurately identifying bone metastases and distinguishing them from benign conditions that may mimic metastases in patients with cancer.

This hybrid imaging technique aids in clinical decision-making regarding staging, restaging, and treatment strategies for patients with skeletal metastases, enhancing the management of their condition.
