Treatments being tested: Both Keramod and Aldara contain imiquimod, which stimulates the immune system to attack abnormal skin cells. Keramod is applied as a gel, while Aldara is applied as a cream.
Study on Cryotherapy and Tirbanibulin for Treating Actinic Keratosis on the Scalp and Forehead in Patients Aged 18 and Older
This trial evaluates a combination treatment approach using cryotherapy followed by Klisyri ointment containing tirbanibulin for lesions on the scalp and forehead.
Who can participate: Patients aged 18 or older with at least 8 visible or touchable lesions on the scalp and forehead are eligible. Lesions must be distributed in two non-overlapping zones of similar severity. Participants must be in good general health and able to understand and follow study procedures. Social insurance is required.
Who cannot participate: Patients younger than 18 or without lesions on the scalp and forehead are excluded.
What the trial involves: Treatment begins with cryotherapy, which uses extreme cold to destroy abnormal tissue. This is followed by application of tirbanibulin ointment to the treated areas. At 4 months, if lesions persist, another cryotherapy session may be administered. Complete response is assessed at 8 months, with a final evaluation at 12 months. Local skin reactions and pain are monitored throughout.
Treatments being tested: Cryotherapy freezes abnormal cells, while tirbanibulin ointment stops the growth of abnormal cells by inhibiting tubulin polymerization, which disrupts cell division.
Study on the Effectiveness and Safety of Metformin and Methyl Aminolevulinate in Daylight Therapy for Actinic Keratosis Patients
This study evaluates topical metformin combined with daylight photodynamic therapy using methyl aminolevulinate hydrochloride for treating lesions caused by sun exposure.
Who can participate: Males and females over 18 with at least 5 lesions on the face or scalp are eligible. Women of childbearing potential must use effective contraception throughout the study.

Treatments being tested: Topical metformin is being evaluated for its potential to enhance treatment effects by affecting cellular energy processes. Methyl aminolevulinate is activated by daylight to treat lesions through photodynamic therapy.
Study on 5-Fluorouracil and Calcipotriol for Treating Actinic Keratosis in Patients
This trial compares a combination treatment of 5-Fluorouracil and Calcipotriol with 5-Fluorouracil alone over four weeks.
Who can participate: Adults over 18 with a diagnosis of the condition by a dermatologist are eligible. The diagnosis should be in areas such as the face, ears, balding scalp, neck, chest area, or upper arms. Participants must have at least 4 lesions in a treatment area no larger than 100 square centimeters, classified as Olsen grade I-III.
Who cannot participate: Patients outside the age range, those in vulnerable populations, patients without the condition, those unable to follow the treatment plan, patients with interfering medical conditions, those participating in another trial, patients with allergies to study medications, pregnant or breastfeeding women, and those with recent treatments or surgeries are excluded.
What the trial involves: Treatment is applied topically for four or six days for the combination group, or four weeks for the 5-Fluorouracil alone group. Evaluations occur at 3 and 12 months post-treatment to assess reduction in lesions, complete clearance, recurrence rates, and adverse effects. Quality of life is measured using questionnaires, and treatment adherence is monitored.
Treatments being tested: 5-Fluorouracil is an antimetabolite cream that interferes with DNA synthesis in abnormal cells. Calcipotriol is a vitamin D analog that helps regulate skin cell growth and enhances the effect of 5-Fluorouracil when used in combination.
Study on the Effectiveness and Safety of Cryotherapy and Tirbanibulin for Actinic Keratosis in Organ Transplant Patients
This study focuses on patients who have received a solid organ transplant, testing a combination of cryotherapy and tirbanibulin ointment.
Who can participate: Solid organ transplant recipients aged 18 or older with the condition are eligible. At least one year must have passed since transplant, and immunosuppressive treatment should be stable for at least 6 months. Participants must have 4 to 8 lesions in two symmetrical areas of 25 square centimeters on the face or scalp. Women of childbearing potential must use reliable contraception during and for one month after the study.
Who cannot participate: Patients without the condition, those who are not transplant recipients, patients under 18 or over 65, and those in vulnerable populations are excluded.
What the trial involves: Two symmetrical skin areas are treated: one with both cryotherapy and tirbanibulin, the other with cryotherapy alone. Cryotherapy is applied first, followed by application of Klisyri ointment once daily for five consecutive days. The study monitors changes in lesion numbers over three months, skin reactions, quality of life, and treatment satisfaction.
Treatments being tested: Cryotherapy uses extreme cold to freeze abnormal cells. Tirbanibulin is a microtubule inhibitor applied topically that stops abnormal cell growth, particularly useful for immunosuppressed patients.

Diclofenac Sodium is a non-steroidal anti-inflammatory drug (NSAID) applied as a gel that reduces inflammation and inhibits enzymes contributing to abnormal cell growth.
Summary
The nine ongoing clinical trials for treating this sun-related skin condition reflect a diverse research landscape across Europe. Spain and Germany are leading with multiple trials each, while France, Italy, the Netherlands, and Poland also host significant research. This geographic distribution ensures broad participation opportunities for patients across the continent.
Several treatment approaches are being investigated. Tirbanibulin ointment appears in multiple studies, both as a standalone treatment and in combination with cryotherapy, indicating strong research interest in this microtubule inhibitor. Traditional treatments like imiquimod and 5-Fluorouracil are also being evaluated, sometimes in combination with newer agents like calcipotriol. Natural product-based treatments, such as green tea extract, and innovative approaches like potassium hydroxide solution add to the variety of options under investigation.
Notably, one trial specifically focuses on organ transplant recipients, recognizing the unique needs of immunosuppressed patients. Several studies include long-term follow-up periods, with one spanning three years to assess safety and cancer prevention outcomes. Most trials focus on facial and scalp lesions, which are the most common and concerning locations for this condition.
These trials offer hope for patients seeking more effective, better-tolerated, or more convenient treatment options for managing rough, scaly patches caused by sun exposure.
