About this study
Official title: A Phase Ib Study to Confirm the Pharmacokinetics and Melanogenic Potential of Controlled-Release Bioresorbable Implants of Afamelanotide in Healthy Volunteers
This is a single center, pharmacokinetic and pharmacodynamic study in healthy volunteers. Twenty four subjects will be enrolled in the study and will be assigned to receive either a 16 mg afamelanotide bioresorbable implant from the current manufacturing process or a 16 mg afamelanotide bioresorbable implant from the optimized manufacturing process. Implants will be administered subcutaneously.
The following procedures will be conducted throughout the study:
- Collection of blood samples for analysis of afamelanotide concentrations
- Measurement of skin reflectance for estimation of melanin density, and luminance (L*), blue/yellow colour hue (b*)
- Safety monitoring
Read the detailed description
The objective of the proposed study is to confirm that the pharmacokinetic and pharmacodynamic properties of implants eluting 16 mg of afamelanotide produced by this final optimized manufacturing process are essentially the same as those of implants manufactured with the same formulation that have been used in earlier clinical studies
The study will involve the use of an implant, which comes in the form of a small rod to be administered under the skin.
For this study, afamelanotide has been formulated as a controlled release depot injection (implant). This means that the afamelanotide will be released slowly into the body over a few days. Once inserted, the implant will remain in the body after afamelanotide has been released and will slowly dissolve.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Afamelanotide Group 1 and Afamelanotide Group 2 in people with Healthy, run by Clinuvel Pharmaceuticals Limited 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 8 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 16 Aug 2018. 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 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?
Change in skin melanin density (time frame: 120 days). 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 16 Aug 2018; AzTrials last refreshed its copy on 6 Nov 2026.
