About
The study is an open-label, singel arm, prospective, multicenter phase II trial evaluating the efficacy and safety of Cemiplimab when applied as first-line therapy in patients with locally advanced basal cell carcinoma (BCC), which were not pretreated with hedgehog inhibitors (HHI).
Full description
The present study is an explorative, investigator-initatied, single-arm, multicentre phase II trial. Patients with locally advanced BCC without pretreatment with hedgehog inhibitors such as vismodegib and sonidegib will receive Cemiplimab (350 mg, i.v.) at day 1 of each 21 days cycle for up to 12 months (max. 17 cycles) or until intolerable toxicity or disease progression, whatever occurs first. All patients will be followed up until death or for up to 12 months after last patient last application of Cemiplimab. The treatment response will be assessed every 12 weeks (± 7 days) during the treatment and the follow up phase. In addition, tumor samples will be collected and used for translational research providing the basis for the establishment of potential biomarkers correlating with the efficacy of Cemiplimab. The primary objective of this study is to evaluate the efficacy of Cemiplimab when applied as first-line treatment in advanced, HHI naïve BCC measured by objective response rate (ORR) after 6 months of treatment. Secondary objective is to evaluate the safety and tolerability of Cemiplimab as first-line treatment in advanced BCC.

Inclusion criteria
Signed informed consent form available
Patient* 18 years or older at time of signing informed consent form
Centrally confirmed histological diagnosis of BCC
NOTE: Tumor tissue to be sent to Central Pathology during screening procedure:
Locally advanced stage without distant metastases, not amenable for surgery or radiotherapy or surgery/radiotherapy contraindicated or refused by patient (as evidenced in source data)
Expected survival of at least 6 months
ECOG performance status 0 or 1
Adequate laboratory parameters particularly for the blood count, renal and liver function parameters.
Absence of other severe comorbidities
Resolution of any acute, clinically significant treatment-related adverse events from prior therapy/procedure to Grade ≤ 1 prior to study entry, with the exception of alopecia.
Negative serum pregnancy test done less than or equal to 7 days prior to enrollment, for females of childbearing potential only.
Sexually active women of childbearing potential (WOCBP) and men with WOCBP partners must be prepared to use suitable contraceptive method with a failure rate of < 1% per year during the treatment period and for at least 6 months after the last dose of Cemiplimab
Exclusion criteria
Pretreatment with systemic immunotherapy (such as PD-1/PD-L1 or CTL4) or targeted therapy (such as hedgehog inhibitor) NOTE: Prior treatment with imiquimod or other topical or intralesional immune modulators will not be exclusionary
Any other non-radiation anti-cancer therapy (e.g. imiquimod, photodynamic therapy; neither investigational nor standard of care) within 30 days (from date of last administration) of initial Cemiplimab administration or if planned during the study duration
Ongoing or recent (within 5 years) evidence of significant autoimmune disease that required systemic immunosuppressive therapy, excluding: vitiligo, childhood asthma that has resolved, type 1 diabetes, residual hypothyroidism requiring only hormone replacement, or psoriasis that does not require systemic treatment
Other neoplasia, in particular hematologic diseases that might impair immune response, such as chronic lymphocytic leukemia, myelodysplastic or myeloproliferative disease and patients with Gorlin-Goltz syndrom
Immunosuppressive corticosteroid doses (> 10 mg prednisone daily or equivalent) within 4 weeks prior to the first dose of Cemiplimab NOTE: Patients who require brief courses of steroids (e.g., as prophylaxis for imaging studies due to hypersensitivity to contrast agents) are eligible for participation. Furthermore, patients who received mineralocorticoids (e.g., fludrocortisone), corticosteroids for chronic obstructive pulmonary disease (COPD) or asthma, or low-dose corticosteroids for orthostatic hypotension or replacement in case of adrenal or hypophysis insufficiency are eligible for participation.
Known allergic/hypersensitive reaction to the study drug and any of its excipients or history of documented allergic/hypersensitive reactions to antibody treatments
Active infection requiring systemic therapy, including uncontrolled HIV, HBV and HCV infection or diagnosis of immunodeficiency.
NOTE: Patients are eligible if:
History of pneumonitis within the last 3 years
Patients with history of solid organ transplant (patients with prior corneal transplants may be allowed to enroll after discussion with and approval from the Lead Investigator)
Comorbid systemic illnesses or other severe concurrent disease which, in the judgment of the investigator, would make the patient inappropriate for entry into this study or interfere significantly with the proper assessment of safety and toxicity of the prescribed regimens
Receipt of live vaccines (including attenuated) within 30 days of first administration of Cemiplimab
Pregnancy or lactation period.
Medical or psychological conditions that would not permit the patient to complete the study or sign informed consent.
Substance abuse, medical, psychological or social conditions that may interfere with the patient's participation in the study or evaluation of the study results
Legal incapacity or limited legal capacity.
On-treatment participation in another clinical trial in the period 30 days prior to start of the study treatment and during the study
