Study summary

Nail psoriasis can change how your nails look and cause pain, making everyday activities uncomfortable and affecting your confidence. Treatments include creams or ointments, injections, medicines that work throughout the body, and laser therapy. The choice depends on your age, symptoms, overall health, preferences, and possible side effects.

Steroid injections can help, but they may be painful and can cause bruising under the nail or thinning of the skin around the injection site. Fractional CO2 laser creates tiny channels in the nail to help medicines applied to it pass through more easily. Studies have reported improvement with laser treatment, although adding certain ointments has not always worked better than laser alone.

Tacrolimus 0.1% ointment has also shown promising results. The proposed study aims to find out whether combining this ointment with fractional CO2 laser works better than using the ointment alone.

Read the detailed description

Nail psoriasis is a common finding in psoriatic patients with a negative impact on the quality of life. The cosmetic disfigurement leads to social embarrassment and the associated pain may interfere with the daily physical activities1.2.

Therapeutic options for nail psoriasis include topical, intralesional, systemic agents, and laser treatment. The choice of treatments depends on multiple factors, including the age, the burden of the disease, accompanying diseases, individual preferences, and the risks of treatment 3.

Intramatricial corticosteroid injection has been used for many years in nail psoriasis with good results; the steroid of choice is triamcinolone acetonide despite its efficacy, the intralesional injection can be quite painful and pain management methods may be required before treatment. It can also be associated with adverse effects, such as subungual hematoma formation and injection site atrophy 4,5.

Ablative fractional CO2 laser (FCL) has been commonly used for the treatment of nail diseases owing to its ability to create microchannels to enhance drug permeation and assist the transungual delivery of topically applied drugs suggesting that it might be useful in the treatment of nail psoriasis6,7.

Fractional CO2 laser combined with topical methotrexate on one side and topical (calcipotriol/betamethasone) on the other side in nail psoriasis and showed marked clinical improvement with both regimens 8.

Another study was done to compare fractional CO2 laser versus fractional CO2 laser plus betamethasone/calcipotriol ointment in treatment of nail psoriasis.

Topical vitamin D derivatives with corticosteroids show improvement in nail psoriasis in the combined therapy group. This improvement was not superior to fractional CO2 laser monotherapy 9.

Tacrolimus 0.1% ointment has been studed in the treatment of nail psoriasis with a good clinical response 10.

To the best of our knowledge, no studies were found to compare efficacy of fractional CO2 laser combined with topical tacrolimus 0.1% in the treatment of nail psoriasis.

Study arms

  • Active comparator
    fractional with tacrolimus

    one finger nail receiving fractional carbon dioxide laser followed by topical tacrolimus

    Device: fractional C02 laser

  • Active comparator
    topical tacrolimus

    one similar fingernail on the opposite hand receiving only topical tacrolimus 0.1

    Drug: Topical tacrolimus 0.1% ointment

Interventions

  • Devicefractional C02 laser

    three sessions of fractional CO2 laser with 4-week intervals in addition to topical tacrolimus 0.1% ointment, applied right after the treatment and in between sessions. The DEKA fractional CO2 laser will be used with the following parameters: 20 W, 2000-ms dwell time, 5 stacks, and 500-mm spacing.

  • topical tacrolimus oint 0.1% will be applied to the fingernail daily for 3 months

1 registry update since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Nov 2026; primary completion for Feb 2027, 3 months later.

Of 115 non-industry interventional studies with no phase under Psoriasis, half reached primary completion within 21 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 41. This study's planned 3 months is below that.

Counting every sponsor, half of 134 studies reached it within 19 months; a quarter within 8 and three quarters within 38.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
