About this study
Official title: A Phase 2 Study to Evaluate the in Vivo Biodistribution, Radiation Dosimetry and a Preliminary Assessment of the Diagnostic Performance of [18F]BL40
CXCR4 is type of receptor that has been detected in more than twenty different subtypes of cancers. Most of these cancers are associated with negative symptoms that worsen over time resulting in great disability and poor function. There is a need for novel tracers to image CXCR4-expressing tumors for better detection, staging, and monitoring of aggressive cancers without the need for invasive biopsy procedures that may not always properly capture the extent of a patient's disease.
This study looks to assess the safety and efficacy of a novel radiopharmaceutical known as 18F-BL40 through its use in a PET/CT scan. Participants will receive 2 PET/CT scans:
18F-BL40 and 18F-FDG as part of this study.
Read the detailed description
This is a prospective registry study to evaluate the diagnostic utility of 18F-BL40 PET/CT to stage patients with CXCR4-expressing tumors, localize sites of tumors and assess safety and biodistribution of this drug in PET/CT scans.
Each subject will receive two PET/CT scans, one using 18F-BL40 and the other using 18F-FDG. The 18F-BL40 radioactive tracer is manufactured for this study under a Clinical Trial Application filed with Health Canada. 18F-FDG is considered standard care and has been approved by Health Canada.
Follow-up assessments: All subjects will be contacted by phone the day after the injection of 18F-BL40. The subjects will be asked if they experienced any undesirable effects during the 18-72 hours after the administration of 18F-BL40. The local site attending nuclear medicine physician will then make an assessment as to whether these effects are likely related to 18F-BL40 administration.
All subjects will be followed for at least 6 months following the 18F-BL40 PET/CT exam. The evaluation will include a chart review of available imaging, laboratory tests, and treatment. The data required can be obtained from a review of the patient's paper and electronic charts, supplemented by telephone contact as needed to complete the information.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
18F-BL40 PET/CTDiagnostic test
Phase 1 (Patients 1-10):
Vital signs will be recorded prior to the BL40 injection. Each study subject will have an intravenous catheter inserted. Prior to the radiotracer injection an ultra low dose CT will be taken. The subject will receive a bolus intravenous dose of the 18F-BL40. A Dynamic PET scan will be taken of the heart followed by serial whole body PET scan will be done. Vital signs will be taken again and the subject will have a bathroom break. The patient will return to the scanner bed for a standard low dose CT and whole body PET scan. Vital signs will be taken again, and subject will be allowed to use the washroom again. The subject will return to the scanner bed for the final time for an ultra low dose CT and whole body PET scan. A final set of vitals will be taken and the subject will be discharged.
Phase 2 (11-30):
IV bolus dose of BL40, 1 hours uptake time followed by 15-minute static scan. No vital signs taken.
18F-FDG PET/CTDiagnostic test
The patient will return on another day for the 18F-FDG PET/CT scan. A fasting period of 6 hours is required before this scan.
Each study subject will have an intravenous catheter inserted. The subject will receive a bolus intravenous dose of the radiotracer from an approved study supplier site.
The subject will rest in a comfortable chair for 60 minutes. The subjects will then be taken to a designated washroom and asked to void prior to being scanned in order to clear excreted radiotracer activity from the urinary tract.
Subjects are positioned supine, arms down, and centered on the scanner bed and the PET/CT images will be acquired.
Routine Blood Draw - Phase 1 onlyDiagnostic test
Complete blood counts and routine clinical chemistry performed before and repeated within 18-72 hours after 18F-BL40 administration.

Questions about this trial
What is this clinical trial studying?
An observational study of Diffuse Large B-cell Lymphoma and Multiple Myeloma, run by British Columbia Cancer Agency at 1 site in Canada.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 10 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 1 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Pav Ravi (6048776000 ext. 2818, pavithraa.ravi@bccancer.bc.ca), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
To determine the tolerability of [18F]BL40 (time frame: 1 hour post injection, 2 hours post injection and 18-72 hours post injection). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Oct 2026.
