Study Summary

The study aim is to assess the immunological and clinical response in basal cell carcinoma (BCC) treated with ablative fractionated laser (AFL) as monotherapy and compare with BCC treated with combination-therapy of AFL and the anti-PD1-drug nivolumab and with nivolumab as monotherapy.

Eligibility Criteria

Inclusion

Inclusion Criteria:

  • Patients 18 years or older

  • Clinical suspicion of BCC or histologically verified BCC at baseline andhistologically verified BCC at visit 2, irrespective of histologic subtype withdiameter ≥7 mm at baseline.

  • Signed informed consent.

  • Female subjects of childbearing potential* must be confirmed not pregnant by anegative pregnancy test prior to study treatment and must use a safe contraceptivemethod

Exclusion

Exclusion Criteria:

  • Concomitant treatment with 5-FU or imiquimod

  • Concomitant chemotherapeutic treatment

  • Concomitant systemic immunotherapeutic treatment, including Prednisolone

  • Pregnant or lactating women

  • Allergies to anti-PD1

  • Patients with a tendency to form keloids

  • Other skin diseases or tattoos in the treatment area

Study Description

Explorative open label study. Patients and investigators are non-blinded and patients not randomized to interventions.

Three intervention groups:

  1. AFL monotherapy (8-10 patients)

  2. AFL+intratumoral nivolumab (8-10 patients)

  3. Intratumoral nivolumab monotherapy (8-10 patients)

Patients will attend 4 visits Immunological response is determined by immunohistochemistry (IHC) analysis from biopsies taken prior to AFL, AFL+Nivolumab or Nivolumab treatment (baseline) and compared with biopsies 1 week after treatment. Further, comparison of the immunological response of AFL monotherapy with immunological response AFL+Nivolumab and Nivolumab as monotherapy will be performed.

Patients included for AFL as monotherapy will after tumor demarcation receive AFL of the BCC including a 5 mm margin. An occlusive bandage will be applied to the treated area and is to be removed by the patient 24 hours after treatment or after end of secretion/oozing from the treated area.

Patients included for AFL+Nivolumab will after tumor demarcation receive AFL of the BCC including a 5 mm margin, immediately followed by intratumoral injection of Nivolumab. An occlusive bandage will be applied to the treated area and is to be removed by the patient 24 hours after treatment or after end of secretion/oozing form the treated area.

Patients included for monotherapy with Nivolumab will after tumor demarcation get an intratumoral injection of Nivolumab. An occlusive bandage will be applied to the treated area and is to be removed by the patient 24 hours after treatment or after end of secretion from the treated area.

All patients will have a final visit at week 15, around 12 weeks after first treatment, where the clinical response will be evaluated, and treated tumor will be treated following national guidelines for treatment of BCCs.

For subgroups of clinical responders and non-responders tumor will at week 15 be used for multiplex gene expression analysis via nanostring (Pan cancer immune profiling panel).

For all groups, clinical photographs are taken at every study visit. For patients that present with more than one tumor, patients will be invited to participate with all tumors relevant to the study.
