  • If a women of child-bearing potential (WOCBP), that is, 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: a) Have a negative urine pregnancy test using a highly sensitive method at screening and on Day 1 prior to treatment administration. b) Be using effective methods of birth control. c) Agree to have pregnancy tests while in the study and at the end of the study
  • Participants should be willing to avoid sunlight or ultraviolet (UV) light exposure, including the use of tanning beds, to the face or scalp during the study
  • Participants 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
Exclusion Criteria
  • The location of the TF is: a) on any location other than the face or scalp. b) within 5 centimeters (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
  • Presence in the TF of: a) clinically atypical and/or rapidly changing AK lesions b) hyperkeratotic or hypertrophic lesions, recalcitrant disease (had cryosurgery on 2 previous occasions), and/or cutaneous horn. c) confluent AK lesions (that is, non-discrete lesions, as per inclusion criterion 2). d) Persisting AK lesions at the screening visit following topical treatment with diclofenac sodium 3 percent (%) gel
  • 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
  • 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

GroupInterventionDescription
Diclofenac Sodium 3% GelDiclofenac Sodium 3% GelParticipants will apply diclofenac sodium 3% gel twice daily to the TF for 60 to 90 days beginning Day 1, with the option of further courses every 6 months (with at least 6 months between starting date of treatment courses) if lesions are found to be present in the TF at follow up visits and physical treatment is not appropriate.
Tirbanibulin 10 milligram per gram (mg/g) ointmentTirbanibulin (Klisyri®) 10 mg/g ointmentParticipants will apply tirbanibulin ointment 10 mg/g once daily to the treatment field (TF) for 5 consecutive days beginning Day 1. At subsequent visits, participants will have the option of an additional 5-day course(s) (with at least 16 weeks between starting date of treatment courses) at the discretion of the investigator if actinic keratosis (AK) lesions are present in the TF and physical treatment is not appropriate.
Primary Outcome Measures
NameTimeMethod
Percentage of Participants with Histologically Confirmed Invasive Squamous Cell Carcinoma (SCC) in the Treatment Field (TF)Up to 3 years

Percentage of participants with histologically confirmed invasive SCC in the TF will be reported as assessed by dermoscopy.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants With any Other Skin Cancer (Other Than SCC) in the TFUp to 3 years

Percentage of participants with any other skin cancer (other than SCC) in the TF will be reported.

Time to Occurrence of Invasive SCC From Baseline in the TFUp to 3 years

Time to occurrence of invasive SCC from baseline in the TF will be reported.

Percentage of Participants Requiring Rescue Treatment After 1 Treatment CourseUp to 3 years

Percentage of participants requiring rescue treatment after 1 treatment course will be reported.

Percentage of Participants With no Lesions After Treatment of the First Recurrence With Tirbanibulin During the First 52 WeeksUp to Week 52

Percentage of participants with no lesions after treatment of the first recurrence with tirbanibulin during the first 52 weeks will be reported.

Number of Participants With Vital Signs AbnormalitiesUp to 3 years

Number of participants with vital signs (including measurement of heart rate, respiratory rate, systolic and diastolic blood pressure and tympanic temperature) will be reported.

Number of Participants With Physical Examination AbnormalitiesUp to 3 years

Number of participants with physical examination abnormalities (height, weight and an assessment of head, eyes, ears, nose and throat, integumentary/dermatological, gastrointestinal, cardiovascular, respiratory, musculoskeletal, and neurological systems) will be reported.

Number of Participants With Adverse Events (AEs)Up to 3 years

An Adverse Event (AE) is defined as any untoward medical occurrence in a participant or clinical investigation participant administered an Investigational Product. An AE does not necessarily have a causal relationship with the medicinal product.

Number of Participants With Serious Adverse Events (SAEs)Up to 3 years

A Serious Adverse Event (SAE) is defined as any untoward medical occurrence that at any dose, resulted in death, was life-threatening (i.e, the participant was at immediate risk of death from the AE as it occurred; this did not include an event that, had it occurred in a more severe form or was allowed to continue, might have caused death), required in-patient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect (in the child of a participant who was exposed to the study drug).

Percentage of Participants Requiring Rescue Treatment at Any Time During the StudyUp to 3 years

Percentage of participants requiring rescue treatment at any time during the study will be reported.
