Clinical Trial Summary

A single center, open-label, phase IIa, single arm, window of opportunity trial with IO103 and Montanide adjuvant in patients with surgically resectable BCC.

Description:

10 patients with BCC will be vaccinated with a peptide derived from the immune checkpoint molecule PD-L1. Patients will be vaccinated once every 2 weeks (Q2W) for 10 weeks and then evaluated for a clinical response.

Patients with clinical response to vaccination will continue with one vaccination once every 4 weeks (Q4W) for 12 weeks and thus receive 9 vaccinations in total over the course of 22 weeks.

Patients with no effect of treatment after 6 vaccinations will be treated with standard of care (SOC).

9. Significant medical disorder according to investigator; e.g. severe asthma or chronic obstructive lung disease, dysregulated heart disease or dysregulated diabetes mellitus

10. Concurrent treatment with other experimental drugs

11. Any active autoimmune diseases e.g. autoimmune neutropenia, thrombocytopenia or hemolytic anemia, systemic lupus erythematosus, scleroderma, myasthenia gravis, autoimmune glomerulonephritis, autoimmune adrenal deficiency, autoimmune thyroiditis etc.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Clinical response	Evaluation and measurement of target BCC in cm2. Clinical response is evaluated as change in tumor size in mm.	All patients were evaluated 3 Month after last vaccination
Primary	Disease control rate	Defined as change of the largest diameter of target BCC	After 6 vaccinations with IO103 (10 weeks)
Primary	Immune responses	Immune responses in biopsies from basal cell carcinomas (BCC). Analyses which will include (but are not restricted to): Immunosign®CR/Pan Cancer Immune panel (gene expression level of multiple immune genes); Halioseek® CD8/PDL1(PDL1/CD8, CD8+ quantification by digital pathology, PDL1+ tumoral cells and Immune cells analysis by a pathologist); Immunoscore (CD3 and CD8 immune histochemistry (IHC) testing, scanning and image analysis); MHC Class I and II (IHC, scanning and image analysis)	After 6 vaccinations with IO103 (10 weeks)
Secondary	Immune responses in skin	Immune responses in skin delayed type hypersensitivity (DTH). Skin-infiltrating lymphocytes (SKILs) are tested for specificity to the PD-L peptides as a sign of induction of a functional immune response	After 6 vaccinations with IO103 (10 weeks)
Secondary	Incidence of treatment emergent adverse events (safety and tolerability)	Events will be recorded and graded using CTCAE version 4.03	From the time that the subject provides written informed consent and throughout the trial duration, until 30 days post last dose of trial treatment
