Summary

This trial is for patients with suspected bacterial infection who are at least 18 years old. The trial will have two cohorts: one for biodistribution and one for dynamics. Each cohort will have a different PET/CT scan. Blood tests will also be done.

Who is the study for?

This trial is for adults with suspected bacterial infections, primarily those receiving care at the University of Pennsylvania. It's not suitable for pregnant or breastfeeding women, people who can't tolerate imaging procedures, have taken trimethoprim within 48 hours before the baseline scan, or have serious medical conditions that may affect their safety in the study.

What is being tested?

The trial tests how a radioactive drug called 11C-Trimethoprim spreads and moves through the body using PET/CT scans. Participants are divided into two groups: one undergoing several scans over about 2.5 hours and another having an hour of dynamic scanning followed by up to two static scans.

What are the potential side effects?

While specific side effects aren't listed for this imaging agent, typical risks might include reactions to the tracer like rash or itching, discomfort from lying still during scanning, and exposure to radiation from both PET and CT components.

Experimental Treatment

Group I: DynamicExperimental Treatment1 Intervention

The Dynamic cohort will undergo approximately 60 minutes of dynamic scanning followed by up to 2 static skull base to mid-thigh (or feet if indicated) scans imaging post injection of \[11C\]trimethoprim. Some subjects who may be selected clinically to undergo surgical or antibiotic treatment may undergo a second therapy may also undergo an optional second \[11C\]trimethoprim PET/CT after the initiation of therapy to collect pilot data on the changes in \[11C\]trimethoprim biodistribution and uptake with therapy, the timing of this scan may vary depending on the type of treatment the patient is receiving.

Group II: BiodistributionExperimental Treatment1 Intervention

The Biodistribution cohort referred from orthopedics who will undergo a series of vertex to mid-thigh (or feet if indicated) biodistribution \[11C\]trimethoprim PET/CT scans over a period of approximately 2 ½ hours.
