Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

Ages 12 years and older
All sexes
No healthy volunteers
Child, Adult, Older adult

Who may be able to join

Male or female sex; ≥12 years of age at Baseline (Visit 2).
Have a molecular (genetic) diagnosis of PRPF31 mutation.
Have a clinical diagnosis of PRPF31 mutation-associated retinal dystrophy, that is, RP11. The following conditions are allowed for inclusion if due to RP11, if in the opinion of the investigator they will not interfere with study evaluations or have resolved: macular edema (intraretinal, sub-retinal or other fluid) requiring regular treatment at a frequency of less than every 6 weeks; macular edema must be stable for at least 3 months prior to Screening (Visit 1). The investigator must consult with the study Medical Monitor.
If ≥18 years of age, understand the language of the informed consent and are willing and able to provide written informed consent prior to any study procedures. If a minor (12 to <18 years of age), a parent or legal guardian willing and able to provide written permission for the minor's participation prior to performing any study related procedures and pediatric participant able to provide age appropriate assent for study participation.
If ≥18 years of age, are willing to comply with the instructions and attend all scheduled study visits. If a minor (12 to <18 years of age), able to complete all study assessments, comply with the protocol, and has a parent or caregiver willing and able to follow study instructions and attend study visits with the participant as required, in the opinion of the Investigator.
Meets ≥1 of the following for visual function in the study eye:

V4e visual field >1000 deg2, per kinetic perimetry
<Mean microperimetry threshold: >5 decibel (dB) to <15dB
Visual acuity: 20/40 to 20/200 inclusive (>35 and <70 letters by Early-Treatment Diabetic Retinopathy Study [ETDRS])

FST baseline no worse than -20 dB
Participants of childbearing potential and male participants must not be pregnant or lactating and must be sexually inactive by abstinence, which is consistent with the preferred and usual lifestyle of the participant or agree to use adequate birth control throughout study duration. Adequate birth control is defined as hormonal - oral, implantable, injectable, or transdermal contraceptives; mechanical - spermicide in conjunction with a barrier such as a condom or diaphragm; intrauterine device (IUD); or surgical sterilization of partner. For nonsexually active participants, abstinence may be regarded as an adequate method of birth control. Participants of childbearing potential include all participants who have experienced menarche and have not undergone successful surgical sterilization (bilateral tubal ligation, hysterectomy, or bilateral oophorectomy) or are not postmenopausal (12 months after last menses).

Who cannot join

Have any uncontrolled systemic disease that, in the opinion of the Investigator, would preclude participation in the study that include but are not limited to infection, uncontrolled elevated blood pressure, cardiovascular disease, or glycemic control issues, or any other medical condition that may put the participant at risk due to study procedures.
Mutations in genes that cause autosomal dominant RP, Xlinked RP, or presence of biallelic mutations in autosomal recessive RP/retinal dystrophy genes other than PRPF31 mutations.
Have used anti-vascular endothelial growth factor (VEGF) agents within 2 months or corticosteroid injections within the last 3 months.
Have had Ozurdex
implants placed within 3 months or Retisert
or Iluvien

implants placed within 3 years prior to Baseline (Visit 2).
Within 3 months prior to Baseline (Visit 2), have undergone any vitreoretinal surgery (scleral buckle, pars plana vitrectomy, retrieval of a dropped nucleus or intraocular lens, radial optic neurotomy, sheathotomy, cyclodestructive procedures or multiple filtration surgeries [2 or more]) or any other ocular surgery.
Have ocular media opacity or poor pupillary dilation prohibiting quality ophthalmic evaluation or photography, as assessed by the investigator.
Have used any investigational drug or device within 90 days or 5 estimated half-lives of Baseline (Visit 2), whichever is longer, or plan to participate in another study of drug or device during the study period. Participation in observational trials is allowable based on investigator discretion and consultation with the Medical Monitor. It is assumed that the observational trial evaluations would not interfere with participation in this study.
Have received any prior cell, ribonucleic acid (RNA) (including VP-001), or gene therapy for a retinal condition.
Have a recent history (<6 months) or current excessive recreational drug or alcohol use, in the opinion of the investigator.
Any retinal pathology other than RP11 that in the investigator's opinion could affect study results.
Participants should not have any conditions, in the investigator's opinion, that may put the participant at increased risk, confound study data, or interfere significantly with the participant's study participation.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing VP-001 in people with Retinitis Pigmentosa 11 and Retinal Degeneration, run by PYC Therapeutics at 5 sites 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 12 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 29 May 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites 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?

The incidence, severity, and relatedness of treatment-emergent ocular adverse events and treatment-emergent serious adverse events (time frame: over a 4-week post-dose period). 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?

On the ClinicalTrials.gov record for NCT06455826.

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 29 May 2026.
