Study summary

Evaluation of the Efficacy and Safety of a thermal fractional skin treatment system (Tixel) for the treatment of facial and/or scalp actinic keratoses

Read the detailed description

Single-center, Prospective, Open-Label, with Before-After Study Design. Up to 25 subjects will be enrolled to the study to provide at least 20 evaluable subjects. Subjects will be examined to determine the severity and extent of actinic keratoses.

All subjects will undergo 1-3 treatments (determined by the investigator assessment), 3-4 weeks apart.

Follow-up visits will be performed after the last treatment visit: 4 weeks (±7 days) and 12 weeks (±7 days).

The inclusion criteria would be mild to moderate thickness confluent actinic keratoses located to scalp and/or face.

Each subject will participate in the study for up to 20 weeks. Total study duration is estimated to be up to 12 months from enrollment of the first subject until last subject visit (including FUs).

Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

What researchers measure

Primary outcomes

  1. Efficacy of Tixel for Treatment of Actinic Keratosis

    The overall mean percentage reduction in actinic keratoses lesion count performed by the investigator manually, confirmed and documented using photograph images taken at baseline and at 12 weeks follow-up visit (or 12-weeks post last treatment if less than 3 treatments were done) (before and after marking the present actinic keratoses using a washable eyeliner) calculated as the relative change from baseline at 12 weeks. New lesions which were not existed in baseline will not be counted.

    Time frame: up to 12 weeks post last treatment

Secondary outcomes

  1. Efficacy Evaluation of Tixel for Treatment of Actinic Keratosis

    Time frame: up to 12 weeks post last treatment

  2. Efficacy Evaluation of Tixel for Treatment of Actinic Keratosis

    The overall mean percentage reduction in actinic keratoses lesion count performed by the investigator manually, confirmed and documented using photograph images taken at baseline and at 4 weeks follow-up visit (before and after marking the present actinic keratoses using a washable eyeliner) calculated as the relative change from baseline at 4 weeks follow-up visit. New lesions which were not existed in baseline will not be counted.

    Time frame: up to 4 weeks post last treatment

  3. Efficacy of Tixel for Treatment of Actinic Keratosis - Percentage of Subjects That Demonstrated Reduction in Actinic Keratosis Lesion Count 3 Months After the Last Treatment.

    * Percentage of subjects that demonstrate a 26-50% in reduction in actinic keratoses lesion count 3 months after the final treatment. * Percentage of subjects that demonstrate a 51-75% in reduction in actinic keratoses lesion count 3 months after the final treatment. * Percentage of subjects that demonstrate more than 76% in reduction in actinic keratoses lesion count 3 months after the final treatment.

    Time frame: up to 12 weeks post last treatment

  4. To Evaluate the Subject's Satisfaction.

    Subjects' satisfaction assessed at the final follow-up visit (based on the subject experience questionnaire which includes 3 questions relating to treatment results, treatment experience and treatment expectations) graded on a score of 1- 5; 1 being not satisfied and 5 being very satisfied).

    Time frame: up to 12 weeks post last treatment

  5. Safety Evaluation - Adverse Events

    Procedure-related Adverse events during the study.

    Time frame: up to 12 weeks post last treatment

  6. Subject Subjective Downtime Assessment

    Defined as the period of time following the procedure during which the subject felt unable/unwilling to go out in public due to skin reactions. The assessment will be recorded by the subject using the Subject Subjective Downtime Assessment following each treatment and will be collected at the site at the follow-up visits up to 4 weeks FU following treatment 3 (third treatment).

    Time frame: up to 4 weeks post last treatment

  7. VAS Assessment

    Procedure related pain by the subjects using VAS for pain of 0-10 where a higher score indicates greater pain.

    Time frame: up to 8 weeks (treatments period)

Timeline

Tracking 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

Ran from May 2022 to primary completion in Sep 2023, 15 months.

Results were first posted in Dec 2024, 1 year 2 months after primary completion.

Of 33 interventional studies with no phase under Keratosis, Actinic, half reached primary completion within 19 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 33. This study's 15 months is below that.

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.
No changes since tracking began. The registry record was last updated on Dec 3, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
