Carbon-11 Butanol: Whole Body Radiochemical and Radiation Safety ([11C]Butanol)

June 16, 2021 updated by: Weill Medical College of Cornell University

Characterizing the Safety of [Carbon-11]Butanol and Estimating the Test-Retest Variance in Measurements of Its Whole Body Biokinetics Under Zero-Biological-Change Conditions

This will be a Phase 1, open label, imaging study of radiochemical and radiation safety in healthy volunteers. Using positron emission tomography (PET) and in-line computed tomography (CT), the whole body (WB) biokinetics of Carbon-11 butanol will be quantified with serial scans acquired every 3 minutes for two hours. Vital signs (VS), electrocardiograms (ECGs) and clinical laboratory tests of intrernal organ function will be acquired before and at several timepoints after administration of the radiopharmaceutical. Radiation exposures will be estimated with the MIRD Formalism.

Study Overview

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Vital signs (VSs) will be measured, electrocardiograms (ECGs) will be acquired, and blood will be sent to the clinical laboratory for safety assessments before a single dose, intravenous (IV) administration of 555 MBq of Carbon-11 butanol. VSs will be re-measured, ECGs will be acquired again, and more blood will be sent to the clinical laboratory for repeat safety assessments after 2 hours of whole body (WB) scanning. WB scanning will consist of imaging acquisition sweeps of 200 cm from head-to-toe over 180 secs (3 min). Up to 40 sweeps per imaging session will be performed. The subjects will then be given a rest period ("coffee break") for about two hours, after which the entire sequence of events will be repeated. The primary outcome measure will be related to radiation safety derived from the areas under the time-activity curves (AUCs) for internal organs. Co-primary clinical safety measures will include changes in VSs, ECG parameters such as the PR and corrected QT intervals, and clinical laboratory tests, such as proteins that reflect renal and hepatic function. Secondary endpoints will include the time-activity curves (TACs) and total volumes of distribution (VT) in several brain regions. The results should allow calculation of the repeatability coefficients (RCs) under zero-biological-change conditions. RC values will be essential for understanding whether future measurements of effect sizes in response to therapeutic maneuvers or the differences between groups are meaningful.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 89 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • able to give informed consent.
  • age 18-89
  • Subjectively healthy and, in the opinion of the investigators, likely to tolerate the imaging procedures and be compliant with the schedule of follow up telephone calls.
  • Normal hemodynamic function. Systolic blood pressure and pulse must be higher than 120 mmHg and 60 beats per minute while sitting. At the discretion of the investigators, people who regularly engage in vigorous exercise more than four times per week may be enrolled if their systolic blood pressure and pulse are higher than 100 mmHg and 50 beats per minute while sitting.
  • Unremarkable electrocardiograms, with PR intervals of less than 200 mSec and QTcF intervals (corrected with Frederica's method) of less than 440 mSec.
  • No concurrent medications with the exception of p.r.n. NSAIDS, which must be discontinued one week prior to PET scanning.
  • Willing and able to refrain from abusing any recreational drugs, including marijuana, and drink less than one unit of alcoholic beverages per day starting one week prior to PET scanning, and avoided for the next four weeks.
  • Willing to refrain from donating blood for four (4) weeks before the study and for four (4) weeks after the study.
  • Willing to refrain from participating in any other research study that requires taking medication for four (4) weeks before the study and for four (4) weeks after the study.
  • Willing to refrain from being vaccinated for four (4) weeks before the study and for four (4) weeks after the study.
  • All clinical laboratory test results within normal limits or not clinically significant. For example, elevated bilirubin levels in subjects with Gilbert's syndrome will be allowed, as will small red blood cell volumes in healthy people with sickle cell trait.

Exclusion Criteria:

  • Subjects may not be a member of a vulnerable population.
  • Women may not be pregnant or breast feeding.
  • History of multiple hypersensitivity reactions (atopia), as indicated by allergies to multiple medications, foods, and seasonal pollens.
  • History, physical examination, or clinical laboratory tests suggestive of a condition, disorder, or disease that could adversely affect drug absorption, distribution, metabolism, or elimination (ADME) of the tracer, including chronic liver or renal failure.
  • Positive urine toxicology screen for recreational drugs other than marijuana.
  • May not have taken any controlled medications, including other study drugs, in the 30 days prior to PET scanning or for 10 half-lives, whichever is longer.
  • May not have donated blood in the 30 days prior to PET scanning.
  • May not have participated in research administering drugs in the last 30 days.
  • May not have been vaccinated in the 30 days prior to PET scanning.
