About this study

The purpose of this study was to determine whether giving insulin like growth factor-I (IGF-I) to adolescent low weight girls is safe and whether this increases levels of bone formation markers.

Read the detailed description

Adolescents with anorexia nervosa (AN) are at high risk for low bone mineral density at a time when healthy adolescents are rapidly accruing bone, with implications for peak bone mass and fracture risk in later life. They are also deficient in insulin-like growth factor I (IGF-I), the bone trophic factor made in the liver in response to growth hormone (GH), despite elevated levels GH. It is possible that deficiency of IGF-I, a hormone very important for the maintenance of skeletal integrity, may contribute to the severe osteopenia seen in AN. The physiologic effects of rhIGF-I treatment in adolescents with AN had not been studied. The goal of this proposal was to investigate the acute effects of rhIGF-I on bone metabolism in adolescent girls with AN.

Specific Aim: It was hypothesized that adolescent AN patients, being IGF-I deficient, would respond to exogenously administered rhIGF-I with elevations in biochemical indices of bone turnover. Therefore, rhIGF-I was administered to AN patients by subcutaneous injection over 10 days with concomitant measurement of indices of bone turnover, and calcium regulatory hormones.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing RhIGF-1 in people with Anorexia Nervosa, run by Massachusetts General Hospital 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 4 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 18 Nov 2021. 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 4 Aug 2011). 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?

Change in Levels of Insulin Like Growth Factor-1 (IGF-I) Following Recombinant Human (rh) IGF-1 Administration in Girls With Anorexia Nervosa (time frame: Baseline and 7-10 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00516386, which also lists 1 linked publication.

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 18 Nov 2021.
