E.3 | Principal inclusion criteria |
1. Male or female and ≥18 years old. 2. A TF on the face or scalp (excluding lips, eyelids, ears, and inside the nostrils), that: • Is a contiguous area measuring 25 cm2, • Contains 2 to 8 clinically typical, visible, and discrete AK lesions, and • Has an overall clinical picture that is consistent with Olsen grade 1. 3. If a WOCBP, ie, fertile, defined as a female in the life period from menarche and until becoming post-menopausal (no menses for 12 months without an alternative medical cause) or permanently sterile (with hysterectomy, bilateral salpingectomy or bilateral oophorectomy at least 3 months prior to Screening), she must: • Have a negative urine pregnancy test using a highly sensitive method at screening and on Day 1 prior to treatment administration. • Be using effective methods of birth control. • Agree to have pregnancy tests while in the study and at the end of the study (according to the Schedule of Assessments in Table 1). 4. Patients should be willing to avoid sunlight or UV light exposure, including the use of tanning beds, to the face or scalp during the study. 5. Patients should have the ability to understand the purpose and risks of the study, willingness and ability to comply with the protocol, and provide written informed consent in accordance with institutional and regulatory guidelines. |

E.4 | Principal exclusion criteria |
1. The location of the TF is: a) On any location other than the face or scalp. b) Within 5 cm of an incompletely healed wound. c) Within 10 cm of a suspected basal cell carcinoma (BCC) or other neoplasm. d) On the lips, eyelids, ears, or inside the nostrils, periorbital, perioral, or the skin surrounding the nostrils. 2. Presence in the TF of: a) Clinically atypical and/or rapidly changing AK lesions b) Hyperkeratotic or hypertrophic lesions, recalcitrant disease (had cryosurgery onc2 previous occasions), and/or cutaneous horn. c) Confluent AK lesions (ie, non-discrete lesions, as per inclusion criterion 2). d) Persisting AK lesions at the screening visit following topical treatment with diclofenac sodium 3% gel. 3. History of any malignant skin tumour in the TF or history of skin tumour in any region of the body which has metastasized or in which metastasis within the study period is likely. 4. History of any malignant tumour with systemic antitumor treatment (including radiotherapy) within 12 weeks prior to the Screening Visit or systemic antitumor treatment is expected while on the study. 5. Immunocompromised patients, including patients with a history of chronic systemic lymphoma or chronic myeloid leukaemia, or organ transplant recipients. 6. Any other dermatological disease that causes difficulty with examination within the treatment area. 7. Anticipated need for inpatient hospitalization or inpatient surgery during the study. 8. Previous treatment with tirbanibulin 10 mg/g ointment in the selected TF. 9. Treatment with 5-fluorouracil, imiquimod, ingenol mebutate, diclofenac, photodynamic therapy, or other topical treatments for AK within the TF or within 2 cm of the TF, within 8 weeks prior to the Screening Visit. 10. Use of the following therapies and/or medications within 4 weeks prior to the Screening Visit: a) Treatment with cytotoxic drugs (eg, cyclophosphamide, vinblastine, chlorambucil, methotrexate) b) Treatment with systemic medications that modulate and/or suppress the immune system (eg, cyclosporine, prednisone, methotrexate, alefacept, infliximab, interferons or interferon inducers) c) Use of systemic retinoids (eg, isotretinoin, acitretin, bexarotene) 11. Use of the following therapies and/or medications within 2 weeks prior to the Screening Visit: a) Cosmetic or therapeutic procedures (eg, use of liquid nitrogen, surgical excision, curettage, dermabrasion, medium or greater depth chemical peel, laser resurfacing) within the TF or within a 2 cm margin of the selected TF. b) Acid-containing therapeutic products (eg, salicylic acid or fruit acids, such as alpha and beta-hydroxyl acids and glycolic acids), topical retinoids, or light chemical peels within the TF or within a 2 cm margin of the selected TF. c) Topical steroids within the TF or within a 2 cm margin of the selected TF. d) Artificial tanners within the TF or within a 5 cm margin of the selected TF. 12. History of sensitivity and/or allergy to any of the ingredients in the study medications to tirbanibulin, diclofenac, or nonsteroidal anti-inflammatory drugs (ie, NSAIDs). 13. A skin disease (eg, atopic dermatitis, psoriasis, eczema) or condition (eg, scarring, open wounds) that, in the opinion of the Investigator, might interfere with the study conduct or evaluations, or which exposes the patient to unacceptable risk by study participation. 14. Significant uncontrolled or unstable medical diseases or conditions that, in the opinion of the Investigator, would expose the patient to unacceptable risk by study participation. 15. Females who are pregnant or nursing or who are intending to become pregnant 16. Participated in an investigational drug study during which an investigational study medication was administered within 30 days or 5 half-lives of the investigational product, whichever is longer, prior to screening 17. Patient who is an employee or a relative to an employee at the research site or Almirall |
