An Exploratory, Open Label, Multi-Center, Non-Randomized Study of [F-18]VM4-037
[F-18]VM4-037 is being developed as a diagnostic radiopharmaceutical for PET imaging.
SMI is seeking to determine if [F-18]VM4-037 might be useful as a PET ligand for the in vivo
imaging of CA-IX levels in human tissue.
CA-IX is a very active enzyme which may acidify the extracellular microenvironment of tumor
cells in response to hypoxia. Its expression usually promotes tumor growth and invasion, and
thus impairs prognosis.
VM4-037 presents no known risks from either in vitro study in cell lines or in vivo study in
animals according to in-house preclinical investigations of this compound.
The population to be studied consists of a total of approximately sixteen (16) adult
subjects, which includes four normal, healthy volunteers and twelve cancer subjects with a
confirmed or highly suspected diagnosis of head and neck cancer, non-small cell lung cancer,
large solitary hepatic carcinoma, and renal cell carcinoma as defined by the protocol
This initial trial will be an Exploratory, Phase 0 study designed to evaluate
biodistribution, collect baseline and tumor/background imaging data, and gather preliminary
safety data for this investigational product. The study results will be analyzed and
considered in the design of future clinical trials.
The primary objectives of this exploratory study are:
- To gain information on the bio-distribution of [F-18]VM4-037, to evaluate the PET
images of [F-18]VM4-037 for resolution and signal to background ratio for tumors, and
to determine CA-IX expression in tumor tissues by CA-IX antibody with
- To collect safety data, and to use this eIND in order to obtain the necessary
information to file an IND (Investigational New Drug) application with the FDA (Food
and Drug Administration)
The secondary objectives for this exploratory study are:
- To begin collection of baseline imaging and metabolism data
- To gain information to improve study design for the conduct of future trials
The trial is expected to begin subject enrolment in approximately April, 2009 and end
subject participation in approximately September, 2009, depending on the rate of enrollment.
The subject is expected to attend three visits, adding up to several hours.
The Investigational Product (IP) being tested in this study is [F-18]VM4-037. The
[F-18]VM4-037 will be administered to each qualified subject via a bolus intravenous (IV)
injection. For normal volunteers, the dose will not exceed 20 mCi, as the imaging time for
dosimetry is a minimum of four hours. For cancer subjects, the dose will be closer to 10 mCi
(total imaging time for cancer subjects is about 2 hours).
The procedures for this study include the following:
Obtain Informed Consent, Assign Study Subject Number, Obtain Medical History, Perform
Eligibility Blood Labs, Take Pre-Dose Blood Sample for CA-IX Test, Perform Pre-Dose ECG,
Monitor and Collect Adverse Events, Collect Concomitant Medications, Perform Pre-Dose
Physical Exam, Perform Pre-Dose ECG, Insert IV Line, Take Pre-Dose CBC and Chemistry Blood
Labs, Take Pre-Dose Blood Sample for Metabolite Analysis (if applicable), Take Pregnancy
Test (if applicable), Take Pre-Dose Vital Signs, Prepare and Administer IP, Perform
[F-18]VM4-037 PET Imaging, Take Post-Dose Blood Samples for Metabolite Analysis (if
applicable), Take Post-Dose Vital Signs, Perform Post-dose ECGs, Collect Urine Sample and
Count for Dosimetry (normal only), Monitor Adverse Events, Collect Concomitant Medications,
Perform Physical Exam 24 hr Post-Dose, Take Blood Sample for CBC and Chemistry Labs 24 hr
Post-Dose, Perform ECG 24 hr Post-Dose, Take Vital Signs 24 hr Post-Dose, Monitor and
Collect Adverse Events, Collect Concomitant Medications, [F-18]FDG PET Imaging,
Allocation: Non-Randomized, Endpoint Classification: Safety Study, Intervention Model: Single Group Assignment, Masking: Open Label
Safety will be the outcome demonstrated in this clinical trial through analyses of adverse events in subjects who receive study drug.
(3) study visits, including the initial screening visit, the imaging visit, and the 24 hour follow-up visit
