A Pilot Study to Evaluate Short Term Neoadjuvant Sonidegib Followed by Surgery or Imiquimod in the Management of Basal Cell Carcinomas in Cosmetically Challenging Locations
In Brief
A Phase 2 clinical trial evaluating Sonidegib, Imiquimod, and 2 other interventions for Basal Cell Carcinoma and 3 related conditions. Completed, enrolled 16 participants across 1 site.
Detailed 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.

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