About this study

Official title: Differential Effects of rhGH vs. rhIGF-1 on Cardiovascular Risk Factors in Adult Patients With Growth Hormone Deficiency

The purpose of this study is to see if giving growth hormone or insulin-like growth factor-1 (IGF-1) to subjects with growth hormone deficiency effects cardiovascular risk factors differently.

Read the detailed description

Insulin-like growth factor-1 (IGF-1) in some circumstances acts as the mediator of the metabolic effects of growth hormone. However, there is some evidence to suggest that growth hormone (GH) and IGF-1 act differently in some metabolic pathways. We will study the differences between GH and IGF-1 when provided as therapy for growth hormone deficiency in adults. Specifically we will be assessing if either medication impacts cardiovascular risk factors and if so do they impact risk factors differently. Ten adult males ages 18-65 who are growth hormone deficient on stable medications and with stable magnetic resonance imaging (MRI) findings (in the event of a known pituitary mass) will be recruited for the study.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Recombinant Human Growth HormoneDrug

    Also called rhGH

    300 mcg sc qd (which may be increased to 400 mcg sc qd after 4 weeks)

  • Recombinant Human IGF-1Drug

    Also called rhIGF-1

    30 µg/kg for first 4 weeks (may be increased thereafter based on IGF-1 levels)

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Recombinant Human Growth Hormone and Recombinant Human IGF-1 in people with Growth Hormone Deficiency, run by Columbia University at 1 site in United States.

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 1 inclusion and 8 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: stopped early, as of the sponsor's last update on 17 Jul 2024. 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 United States. 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 combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 17 Jul 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Cardiovascular Serum Risk Markers Including Lipids, IL-6, CRP and Homocysteine (time frame: 2 months). 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 17 Jul 2024.
