Recruiting now · Phase 2

Conditions studied: Cutaneous Squamous Cell Carcinoma (CSCC), Cutaneous Squamous Cell Cancer, Cutaneous Squamous Cell Carcinoma of the Head and Neck, Cutaneous Squamous Cell Carcinoma

In brief

The goal of this clinical trial is to determine whether cutaneous squamous cell carcinoma patients can be cured using only immunotherapy, without surgery or radiotherapy.

World Health Organisation (WHO) performance status of 0-2
Indication for SOC surgery with curative intent ± RT
Screening laboratory values must meet the following criteria: WBC ≥ 2.0x109/L, Neutrophils ≥1.5x109 /L, Platelets ≥100 x109 /L, Haemoglobin ≥5.5 mmol/L, Creatinine ≤1.5x upper limit of normal (ULN), AST ≤ 1.5 x ULN, ALT ≤ 1.5 x ULN, Bilirubin ≤1.5 X ULN (except patients with Gilbert Syndrome, who are eligible when total bilirubin < 3.0 mg/dL).
Women of child-bearing potential (WOCBP) must use appropriate method(s) of contraception. They should use an adequate method to avoid pregnancy for 23 weeks (30 days plus the time required time for nivolumab to undergo five x T1/2) after the last dose of the IMP.
WOCBP must have a negative serum or urine pregnancy test (minimum sensitivity 25IU/L or equivalent units of HCG) prior to the start of ICB.
Patients willing and able to understand the Dutch study information and protocol requirements and comply with the treatment/intervention schedule, scheduled visits, and other requirements of the study.

You may not qualify if…

Distantly metastasized (stadium IVb) CSCC
SCC localized in a mucosal surface (i.e. anus, vulva, penis or mucosal portion of lip)
Patients for whom standard of care treatment consists of definitive (brachy)radiotherapy
Primary or recurrent CSCC appearing in an area that has been previously irradiated
Prior systemic therapy or immunotherapy.
Active human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome (AIDS)
Positive test for hepatitis B virus surface antigen (HBsAg) or hepatitis C antibody (HCV Ab)
Subjects with any active autoimmune disease or a documented history of autoimmune disease, except: subjects with vitiligo, resolved childhood asthma/atopy, residual hypothyroidism due to an autoimmune condition requiring only hormone replacement, psoriasis not requiring systemic treatment, any condition not expected to recur in the absence of an external trigger.
Underlying medical conditions that, in the investigator's opinion, will make the administration of the study drug hazardous or obscure the interpretation of toxicity or AEs
Concurrent medical condition requiring the use of immunosuppressive medications, or immunosuppressive doses of systemic or absorbable topical corticosteroids (up to 5 mg of prednisone per day is allowed)
Patients who are pregnant or breastfeeding
History of allergy to study drug components and/or history of severe hypersensitivity to any monoclonal antibody
Use of other investigational drugs 30 days before study drug administration and 5 half times before study inclusion.
