Criteria

Inclusion Criteria:

• Informed Consent as documented by signature

• Subjects must have an evaluable disease as measured by Immune-related Response criteria, or PERSIST (PET response criteria in solid tumours) criteria in patients with metastatic BCCs without cutaneous lesions.

• Subjects (males and females) aged ≥ 18 years

• Adequate organ function (hematologic, renal, hepatic), as assessed by the study physician. Deviations of the following parameters are allowed upon decision of the investigator in case that these are not considered to be of clinical relevance and/or don't represent organ dysfunction or correspond to allowed comorbidities as specified in section 7.1:

• Absolute neutrophil count >1.5 x 109/l

• Hemoglobin >9 g/dL

• Platelets ≥ 100 x 109/l

• Serum total bilirubin <1.5 x Upper limit of normal (ULN) (or ≤3x ULN, if liver metastases).

• Alanine transaminase (ALT) and Aspartate transaminase (AST) < 3 x ULN or <5 ULN if liver metastases are present

• Patients with Gilbert's Disease and total bilirubin up to 3x ULN may be eligible after communication with and approval from the medical monitor

• Alkaline phosphatase (ALP) ≤2.5x ULN (or ≤5x ULN, if liver or bone metastases)

• Serum creatinine < 2 x ULN

• Creatine phosphokinase (CPK) (also known as creatine kinase (CK)) elevation ≤ grade 2

• Eastern Cooperative Oncology Group (ECOG) ≤2

• Negative pregnancy test in women of childbearing potential

• Anticipated life expectancy >12 weeks

Exclusion Criteria:

• History of documented allergic reactions or acute hypersensitivity reaction attributed to antibody treatments

• Patients with allergy or hypersensitivity to Cemiplimab or to any of the excipients of Libtayo. Specifically, because of the presence of trace components in Cemiplimab, patients with allergy or hypersensitivity to doxycycline or tetracycline are excluded.

• Patients with allergy or hypersensitivity to Sonidegib or to any of the excipients of Odomzo.

• Patients with a history of solid organ transplant (patients with prior corneal transplants may be allowed to enrol after discussion with and approval from the medical monitor)

• Receipt of live vaccines (including attenuated) within 30 days of first study treatment or patient unwilling not to receive them during the treatment and for up to 5 half-lives after the last dose of Cemiplimab

• Known of suspected non-compliance, drug or alcohol abuse

• Inability to follow the procedures of the study, due to language problems, psychological disorders, social conditions or dementia

• Currently receiving treatment with another investigational device or study drug, or <28 days since ending treatment with another investigational device or study drug

• Any anticancer treatment other than radiation therapy (chemotherapy, targeted systemic therapy, imiquimod, photodynamic therapy), investigational or standard of care, within 30 days of the initial administration of Cemiplimab or planned to occur during the study period

• Prior treatment with an agent that blocks the PD-1/PD-L1 pathway

• Prior treatment with other systemic immune-modulating agents within fewer than 28 days prior to the first dose of Cemiplimab. Prior treatment with imiquimod or other topical or intralesional immune modulators will not be exclusionary

• Female subject is pregnant or breast-feeding, or planning to become pregnant or breast-feed, or unwilling to use acceptable method(s) of effective contraception during study treatment and during 20 months after the last dose of Sonidegib; and during 6 months (4 in case of breast-feeding) after the last dose of Cemiplimab in case of a Cemiplimab monotherapy (in case of continuation of treatment as detailed in section 6.1)

• Male subject is planning to procreate, donate Semen, or unwilling to use acceptable method(s) of effective contraception during study treatment and during 6 months after the last dose of Sonidegib or Cemiplimab

• Subject is unwilling to renounce to blood spending during the treatment and during 20 months after the last dose of Sonidegib.

• Subject is unwilling to renounce to any elective surgery during the treatment period and for at least 30 days after the administration of the study drug

• Autoimmune diseases, requiring immunosuppressive systemic corticosteroid doses (10mg prednisone or equivalent), during trial participation or within 4 weeks prior to the first treatment dose. Patients who require brief courses of systemic corticosteroids (eg, as prophylaxis for imaging studies due to hypersensitivity to contrast agents) are not excluded. The following are not exclusionary: vitiligo, childhood asthma that has resolved, type 1 diabetes, residual hypothyroidism that required only hormone replacement, or psoriasis that does not require systemic treatment.

• Impaired cardiac function or clinically significant heart disease, including any of the following:

• Angina pectoris within 3 months

• Acute myocardial infarction within 3 months

• Other clinically significant heart disease (as evaluated by study physician)

• Patients, who are receiving treatment with medications that are known to be strong inhibitors or inducers of CYP3A4/5 or drugs, metabolized by CYP2B6 or CYP2C9 that cannot be discontinued prior to study entry and for duration of the study. Medications, that are strong CYP3A4/5 inhibitors should be discontinued for at least 2 days, and strong CYP3A4/5 inducers for at least 1-week prior initiating HHI

• Other anti-cancer treatment (except for topical therapies, such as cryotherapy, for skin lesions other than aBCC) within 30 days to treatment start

• Uncontrolled infection or active infection requiring therapy, including human immunodeficiency virus (HIV)-1 or HIV-2, hepatitis B virus (HBV), or hepatitis C virus (HCV)

• Previous enrolment into the current study

• Enrolment of the investigator, his/her family members, employees and other dependent persons

• Concurrent malignancy other than aBCC and/or history of malignancy other than aBCC within 3 years of date of first planned treatment dose, except for:

• Tumours with negligible risk of metastasis or death (such as cutaneous squamous cell carcinoma, low-risk early stage prostate adenocarcinoma or other tumours, upon decision of study physician)

• Patients with hematologic malignancies, upon decision of study physician

• Untreated brain metastasis(es) that may be considered active. Patients with previously treated brain metastases may participate provided that the lesion(s) is (are) stable (without evidence of progression for at least 6 weeks on imaging obtained in the screening period), and there is no evidence of new or enlarging brain metastases, and the patients do not require any immunosuppressive doses of systemic corticosteroids for management of brain metastasis(es) within 28 days of the first dose of Cemiplimab.

• History of pneumonitis within the last 5 years
