Key exclusion criteria
1. Females of childbearing potential (a female is considered of childbearing potential unless she is post-menopausal, i.e. no menses for at least 12 consecutive months, or is without a uterus).
2. Location of the selected SCCIS lesion:

1. within 5 cm of an incompletely healed wound
2. within 2 cm of an eye, nose, or ear
3. within 1 cm of a scar
4. on the scalp, digits, lips, hands, feet, or ano-genital region
3. SCCIS lesions that have atypical clinical appearance, e.g. hypertrophic or hyperkeratotic or pigmented or ulcerated.
4. Histological evidence of nodular basal cell carcinoma (nBCC), superficial basal cell carcinoma (sBCC) or invasive squamous cell carcinoma (SCC) of the SCCIS in the biopsy sample.
5. Presence of suspected basal cell carcinoma (BCC) or invasive squamous cell carcinoma (SCC) within 2 cm of the selected SCCIS lesion.
6. Presence of known or suspected metastatic disease.
7. History or evidence of skin conditions other than SCCIS that would interfere with evaluation of the study medication (e.g. eczema, unstable psoriasis, xeroderma pigmentosa).
8. Known sensitivity to any of the ingredients in the study medication.
9. A cosmetic or therapeutic procedure (e.g. use of liquid nitrogen, surgical excision, curettage, dermabrasion, medium or greater depth chemical peel, laser resurfacing)

1. of the selected SCCIS lesion at any time; or
2. within 2 cm of the selected SCCIS lesion during the 4 weeks prior to screening visit; or
3. anticipated treatment within 10 cm of the selected SCCIS lesion during the study.
10. Treatment with 5-fluorouracil, imiquimod, diclofenac, or masoprocol

* of the selected SCCIS lesion at any time; or
* within 2 cm of the selected SCCIS lesion during the 6 months prior to study entry; or
* anywhere during the 4 weeks prior to study entry; or
* anticipated treatment anywhere during the study.
11. Treatment with photodynamic therapy

* of the selected SCCIS lesion at any time; or
* within 10 cm of the selected SCCIS lesion during the 6 months prior to study entry; or
* anticipated treatment within 10 cm of the selected SCCIS lesion during the study.
12. Treatment with ionising radiation

* of the selected SCCIS lesion at any time; or
* within 2 cm of the selected SCCIS lesion prior to study entry; or

13. Treatment with other immunomodulators (e.g. vinblastine, podophyllin, colhamin, camptothecin), cytotoxic drugs (e.g. cyclophosphamide, azathioprine, chlorambucil, nitrogen mustard, methotrexate), or interferon/interferon inducers (other than imiquimod)

* within 4 weeks prior to study entry; or
* anticipated treatment during the study.
14. Use of acid-containing therapeutic products (e.g. salicylic acids or fruit acids, such as a and ß hydroxy acids and glycolic acids), topical retinoids, or light chemical peels

* of the selected SCCIS lesion at any time; or
* within 2 cm of the selected SCCIS lesion during the 4 weeks prior to study entry; or
* anticipated treatment within 2 cm of the selected SCCIS lesion during the study.
15. Treatment with psoralen plus ultraviolet light A [UVA] (PUVA) or use of ultraviolet light B (UVB) therapy

* of the selected SCCIS lesion at any time; or
* anywhere during the 6 months prior to study entry; or
* anticipated treatment anywhere during the study.
16. Use of systemic retinoids (e.g. isotretinoin, acitretin, bexarotene)

* during the 6 months prior to study entry; or
