A Relative Bioavailability Study To Evaluate Safety, Tolerability And Pharmacokinetic Comparability Of Pegvisomant 1 X 30 Mg Vs 2 X 15 Mg Subcutaneously Administered In Healthy Subjects
A Phase 1 study testing 1 x 30 mg/mL pegvisomant and 2 x 15 mg/mL pegvisomant in people with Healthy Volunteers, run by Pfizer at 1 site in Belgium.
Trial summary
The primary purpose of this study is to evaluate pharmacokinetic comparability of 1x30 mg pegvisomant injection administered as a single 1 mL injection versus 2x15 mg/mL pegvisomant administered as two separate 1 mL injections and to characterize the pharmacokinetics of the new 30 mg strength.

- Ages 18 to 55 years
- All sexes
- Healthy volunteers accepted
- Adult
Who may be able to join
- Healthy male and/or female subjects between the ages of 18 and 55 years, inclusive (Healthy is defined as no clinically relevant abnormalities identified by a detailed medical history, full physical examination, including blood pressure and pulse rate measurement, 12 lead ECG and clinical laboratory tests).
- Body Mass Index (BMI) of 17.5 to 30.5 kg/m2; and a total body weight >45 kg (99 lbs).

- Subjects who are willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures.
Who cannot join
- Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at time of dosing).
- A positive urine drug screen.
- History of regular alcohol consumption exceeding 14 drinks/week for females or 21 drinks/week for men (1 drink = 5 ounces (150 mL) of wine or 12 ounces (360 mL) of beer or 1.5 ounces (45 mL) of hard liquor) within 6 months of screening.

- Treatment with an investigational drug within 30 days or 5 half lives preceding the first dose of study medication.
- 12 lead ECG demonstrating QTc >450 msec at Screening. If QTc exceeds 450 msec, the ECG should be repeated two more times and the average of the three QTc values should be used to determine the subject's eligibility.

Herbal supplements and hormonal methods of contraception (including oral and transdermal contraceptives, injectable progesterone, progestin subdermal implants, progesterone releasing IUDs, postcoital contraceptive methods) and hormone replacement therapy must be discontinued 28 days prior to the first dose of study medication. Depo Provera must be discontinued at least 6 months prior to the first dose of study medication. As an exception, acetaminophen/paracetamol may be used at doses of 1 g/day. Limited use of non-prescription medications that are not believed to affect subject safety or the overall results of the study may be permitted on a case-by-case basis following approval by the sponsor.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing 1 x 30 mg/mL pegvisomant and 2 x 15 mg/mL pegvisomant in people with Healthy Volunteers, run by Pfizer at 1 site in Belgium.
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 4 inclusion and 14 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: finished, as of the sponsor's last update on 12 Dec 2013. 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 Belgium. 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.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
AUCinf: Area under the concentration-time profile from time zero extrapolated to infinite time (time frame: 4, 8, 12 (Day 1), 24, 30, 36 (Day 2), 48, 54, 60 (Day 3), 72, 78, 84 (Day 4), 120 (Day 6), 192 (Day 9), 264 (Day 12), 360 (Day 16) hours postdose). The study lists 2 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 12 Dec 2013.
