Description of intervention(s) / exposure
Treatment: Drugs - Sonidegib
Treatment: Drugs - Imiquimod
Treatment: Surgery - Surgery
Other interventions - Best supportive care

Experimental: Sonidegib followed by imiquimod - Sonidegib 200mg taken orally once a day for 12 weeks. COMPLETE OR PARTIAL RESPONSE WITH SUPERFICAL REMNANT LESION For patients with a complete response or a partial response resulting in a superficial lesion, treatment with topical imiquimod for 5 days a week for 6 weeks will be prescribed.

Experimental: Sonidegib followed by surgery - Sonidegib 200mg taken orally once a day for 12 weeks. PARTIAL RESPONSE WITH REMNANT INVASIVE LESION For patients with a no change on BCC size / depth or patients with a partial response but a remaining invasive lesion, will have surgical excscion of the remaining lesion.

Other: Sonidegib then best supportive care - Sonidegib 200mg taken orally once a day for 12 weeks. PROGRESSIVE DISEASE Patients with lesions that have progressed in size and/or depth will receive the best supportive care deemed appropriate by the treating clinician. This may be surgery, imiquimod, a clinical trial treatment, radiotherapy or any combination of these interventions.


Treatment: Drugs: Sonidegib
Sonidegib is a selective and orally bioavailable Smoothened (Smo) antagonist. The dose will be 200mg taken once a day for 12 weeks.

Treatment: Drugs: Imiquimod
Imiquimod is an immune response modifier that promotes NF-kappa-B-mediated secretion of pro-inflammatory cytokines, chemokines and other mediators. These immune responses produce cytotoxic effects that are antiproliferative and anti-tumour. Imiquimod treatment requires an extended treatment period of 6 weeks for superficial BCC. Imiquimod is an option for the treatment of small, low-risk superficial BCC when surgery, curettage or cryotherapy are inappropriate. Treatment with imiquimod will be for 5 days a week for a total of 6 weeks.

Treatment: Surgery: Surgery
Although most BCCs are amenable to surgery, excision of large tumours in aesthetically sensitive sites may compromise function or cosmesis. Patients whose BCC has not shrunk in size or depth following 12 weeks of sonidegib will undergo surgical excision of the remaining tumour.

Other interventions: Best supportive care
Patients with lesions that have progressed in size and/or depth will receive the best supportive care deemed appropriate by the treating clinician. This may be surgery, imiquimod, a clinical trial treatment, radiotherapy or any combination of these interventions

Key exclusion criteria
- Inoperable basal cell carcinoma tumours.

- A concurrent cancer diagnosis requiring any systemic anti-cancer therapy.

- Serious or unstable pre-existing medical conditions or other conditions or laboratory
abnormalities that could interfere with the patient's safety, consent, or compliance.

- History of malabsorption or other conditions that would interfere with the absorption

Summary
Brief summary
In this study, patients with BCC will be given neoadjuvant treatment with a drug called
sonidegib. Sonidegib is a daily tablet usually given for BCC that cannot be removed by
surgery or that has spread through the body. The study aims to see if sonidegib given for 12
weeks will reduce the size of tumours so surgery results in less scarring or may be avoided,
with only short term topical treatment required to treat remaining tumour.
