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.

Condition or disease Intervention/treatment Phase
Basal Cell Carcinoma Basal Cell Carcinoma of Skin, Site Unspecified Skin Cancer Invasive Carcinoma Drug: Sonidegib Drug: Imiquimod Procedure: Surgery Other: Best supportive care Phase 2

Detailed Description:
Surgery is the first line treatment for most basal cell carcinomas (BCCs) with cure rates of 88 to 96%. However, excision of large lesions in sensitive locations such as the face and scalp may result in disfigurement and impairment of function. Neoadjuvant drug treatment given before surgery aims to reduce tumour size so that surgery and recovery is easier. 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. This approach may also reduce the risk of recurrence. To assess response to treatment, we will use a new technology for skin tumours called optical coherence technology (OCT). This is like an ultrasound scan and is non invasive. OCT can detect the extent and nature of the tumour and build a 3D image with great accuracy. OCT will be used together with pathological analysis of tumour tissue to determine response to sonidegib.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 10 participants
Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: This is a pilot study which will evaluate the efficacy and safety of short term neoadjuvant sonidegib followed by surgery or imiquimod in the management of basal cell carcinomas in cosmetically challenging locations, assessed by optical coherence tomography and histopathology. The data from this pilot study may lead to the design of larger scale trials of neoadjuvant targeted therapy with the aim to decrease the morbidity of surgical treatment and increase the probability of a curative resection in larger patient populations.

Arm Intervention/treatment
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.
Drug: Sonidegib
Sonidegib is a selective and orally bioavailable Smoothened (Smo) antagonist. The dose will be 200mg taken once a day for 12 weeks.
Other Names:
  • LDE225
  • Odomzo

Drug: 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.
Other Name: Aldara

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.
Drug: Sonidegib
Sonidegib is a selective and orally bioavailable Smoothened (Smo) antagonist. The dose will be 200mg taken once a day for 12 weeks.
Other Names:
  • LDE225
  • Odomzo

Procedure: 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 Name: Excision of remnant invasive basal cell carcinoma

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.
