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 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Actinic keratoses in sufficient numbers (>10) to warrant PDT therapy in the clinic
  • Able to understand and willing to sign a written informed consent document
  • Female subjects must not become pregnant during the study:
  • The effects of 5-aminolevulinic acid (LevulanTM) on the human fetus are unknown. For this reason, women of child-bearing potential must agree to use contraception (double barrier method of birth control or abstinence) prior to study entry, and throughout study participation. Should a woman become pregnant or suspect that she is pregnant while she is participating in this study, she should inform the treating physician immediately.

Who cannot join

  • Pregnant or nursing.
  • At risk for hypercalcemia (renal disease, sarcoidosis, etc.)
  • Using topical retinoids, since these can exacerbate the post-PDT erythema reaction.
  • Using any topical treatment on their AKs; must stop at least one month prior.
  • Currently undergoing treatment for other cancers with medical or radiation therapy.
  • Patients with a known hypersensitivity to 5-aminolevulinic acid or any component of the study material.
  • Patients with history of a photosensitivity disease, such as porphyria cutanea tarda.
  • Currently participating in another clinical trial.

About this study

This study is open to individuals with Actinic Keratoses (skin lesions that have the potential to turn into skin cancer), who are receiving photodynamic therapy (PDT) as part of their clinical care. The purpose of this study is to test and demonstrate that vitamin D pre-treatment can enhance PDT efficacy in the treatment of Actinic Keratoses.

Participants will be asked to take vitamin D supplements prior to their standard of care PDT treatment.

Participation in the research will last about 3-4 months.

Read the detailed description

The primary objective of this study is to determine whether acute supplementation (neoadjuvant Vitamin D3), adjusted according to baseline Vitamin D status, can improve the clinical PDT response relative to participants receiving PDT alone

The secondary objective of this study is to determine whether gene polymorphisms in VDR and CYP27B1 are predictive for the degree of responsiveness to Vitamin D as a neoadjuvant for PDT.

This study is a non-randomized interventional trial, in which the study group will be compared to a baseline cohort of patients from a previous study who received the same regimen of PDT, but without any Vit D. It is anticipated that 30 participants will be involved in this study.

Being tested
Photodynamic therapy (PDT), Vitamin D3
Medical subject headings
Keratosis, Actinic

What participants receive

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

  • Photodynamic therapy (PDT)Drug

    PDT is a technique that combines a photosensitizing drug and an intense light source to kill tumor cells

    Noninvasive fluorescence dosimetry may be performed on up to 6 lesions. Levulan Kerastick will be applied to each lesion and left to incubate for 30 minutes. Blue light (Blu-U device, 20 J/cm2, 33 minutes) will be administered.

  • Vitamin D3Drug

    D3 pills (10,000 IU each) to be taken daily at home, beginning at either day -5 or day -14, as per their assignment

    Participants will receive a 5-day or 14-day supplementation of Vitamin D10,000 IU depending on their baseline Vitamin D 25 Hydroxy result

Study groups in NCT04140292
Study groupRoleWhat they receive
Vitamin D3 + Photodynamic therapy (PDT)ExperimentalPatients receive Vitamin D3 10,000 IU daily for 5 or 14 days depending on VitD baseline level. They then undergo Photodynamic therapy (PDT) for treatment of actinic keratosis.
Receives: Drug: Photodynamic therapy (PDT); Drug: Vitamin D3

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Clinical PDT Response as Measured by Percent Change in AK Lesions From Baseline to 3 Months

    Clinical PDT response as measured by the percent change of AK lesions 3 months after treatment

    Baseline vitamin D (calcidiol) level will be taken for each patient.

    Measured: 3 months after treatment

Secondary outcomes (4)
  1. Correlation Between Vitamin D Receptor (VDR) Polymorphisms and Percent Reduction in AK

    Whether gene polymorphisms in VDR and CYP27B1 are predictive for the degree of responsiveness (as measured by percent reduction in AK) to Vitamin D as a neoadjuvant for PDT.

    Measured: 3 months after treatment

  2. Number of Participants Reporting 1 or Higher on the Pain Scale

    Pain scale recorded on a 0-to-10 visual/analog scale, with higher scores mean more pain; 0 is no pain, 10 is "the worst pain imaginable". Number of participants receiving treatment that reported a pain level greater than 1.

    Measured: During treatment (at the 5 min mark), and again immediately afterwards.

  3. Tolerability as Measured by Participants' Symptom Score Sheets

    Participants are asked to recall the symptoms they experienced during the week following PDT. The study physician asks them whether they had experienced each of the following 13 symptoms (YES/NO), and positive (YES) answers were summed to create a Side Effects Score (SES). The maximum and minimum possible values are 13 and 0 respectively, with a higher score correlating to poorer participant outcomes.

    The 13 possible side effects were: pain, erythema, scabbing, blistering, erosions, edema, warmth, exfoliation, discharge, hemorrhage, tightness, hyperpigmentation, hypopigmentation.

    Measured: 1 week after treatment

  4. Accumulation of Protoporphyrin IX (PpIX) Within AK

    Accumulation of protoporphyrin IX (PpIX) within AK

    PpIX accumulation in areas of both actinic damage and normal skin will be measured with a fluorescence dosimeter. The level of calcidiol, a clinically accepted marker of vitamin D status, will be measured in each patient to see if supplementation with 10,000 IU of Vitamin D increase the accumulation

    Measured: 3 months after treatment

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Photodynamic therapy (PDT) and Vitamin D3 in people with Actinic Keratosis, run by Case Comprehensive Cancer Center 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 4 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: finished, as of the sponsor's last update on 24 Jun 2022. 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?

Yes. Results are posted in the registry (first posted 24 Jun 2022). 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?

Clinical PDT Response as Measured by Percent Change in AK Lesions From Baseline to 3 Months (time frame: 3 months after treatment). 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 NCT04140292, 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 24 Jun 2022.
