About this study

Official title: A Phase 2a, Randomized, Open-Label Study to Determine the Optimal Dose and Evaluate the Safety, Tolerability, and Pharmacokinetics of Progerinin in Patients With Hutchinson-Gilford Progeria Syndrome (HGPS)

Researchers will compare treatment with progerinin plus lonafarnib vs lonafarnib alone to assess optimal dosing, safety, tolerability, and pharmacokinetics in patients with Hutchinson-Gilford Progeria Syndrome (HGPS). Subjects in the randomized study arms will continue to take the standard of care (SOC), lonafarnib, and will be randomized to either take SOC alone or in combination with progerinin.

Read the detailed description

During this trial, a total of 10 subjects will be randomized in a 4:1 ratio to receive treatment with progerinin plus lonafarnib vs lonafarnib alone. Dose escalation will occur through intra-subject dose titration. Two ascending doses of progerinin will be assessed. The dose levels proposed in this study were determined using body weight based on adult doses assessed in previously completed studies, and on a simulated population pharmacokinetic (PK) model. If systemic exposures of Progerinin in pediatric patients are lower than those in adults, a dose escalation may be added at the end of the study.

Progerinin will be administered, with food. The study treatment is available in sachets of 250 mg or 350 mg and the doses in the study range from 500 to 1500 mg daily, dosed BID (twice a day).

Lonafarnib is considered as the standard of care (SOC) and all subjects in the randomized study arms will continue taking lonafarnib for the duration of the study. Subjects who are not already taking lonafarnib will also have the opportunity to initiate lonafarnib on this study as part of the lonafarnib naïve arm (separate from the randomized study arms).

What participants receive

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

  • ProgerininDrug

    Dosing will be determined based on body weight. Dosing ranges from 500mg to 1500mg daily. Progerinin is available in sachets of 250 mg or 350 mg for oral use.

  • LonafarnibDrug

    Lonafarnib is considered as the standard of care (SOC). Subjects in the randomized arms will continue taking lonafarnib per the package insert. Subjects in the lonafarnib naïve arm will initiate lonafarnib as per FDA-approved study 07-01-7505.

Study groups in NCT06775041
Study groupRoleWhat they receive
Progerinin + LonafarnibExperimentalSubjects who have successfully completed the Screening phase will enter the treatment phase of the study and be randomized to a treatment arm. Subjects randomized to the progerinin + lonafarnib arm will take progerinin at a dose dependent on their body weight and will continue taking lonafarnib per the package insert. For each dose cohort, subjects will complete a 28-day treatment period of toxicity assessment, and a minimum four-month treatment period for plasma progerin evaluation. After the last subject completes the toxicity assessment period, the independent Data Monitoring Committee (iDMC) will meet to confirm that subjects can be escalated to the next dose. All subjects will remain on the current dose until the iDMC decision is confirmed. Each subject will only be escalated to the next dose after their 4-month (±2 weeks) plasma progerin sample is collected.
Receives: Drug: Progerinin; Drug: Lonafarnib
Lonafarnib NaïveOtherSubjects with no prior treatment with lonafarnib (i.e., no commercial or managed access program source) may be enrolled to initiate treatment with lonafarnib monotherapy. These subjects will initiate lonafarnib therapy in preparation for an upcoming phase of the study following the completion of phase 2a. These subjects will be excluded from the analysis of this phase 2a study. They will come to the study site for a baseline visit and at one year for assessment as described later in this protocol.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Progerinin and Lonafarnib in people with Hutchinson-Gilford Progeria Syndrome, run by PRG Science & Technology Co., Ltd. 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 17 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 2 Oct 2026. 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 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?

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 from baseline in plasma progerin concentration (time frame: Baseline and Month 4 of each cohort). The study lists 23 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 2 Oct 2026.
