- 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
You likely can't join if
- 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.
- 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)
- 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
- 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).
- 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.
- 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
