简要总结
A single center, open-label, phase IIa, single arm, window of opportunity trial with IO103 and Montanide adjuvant in patients with surgically resectable BCC.
详细描述
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).

结局指标
主要结局
Clinical response
时间窗: All patients were evaluated 3 Month after last vaccination
Evaluation and measurement of target BCC in cm2. Clinical response is evaluated as change in tumor size in mm.
Disease control rate
时间窗: After 6 vaccinations with IO103 (10 weeks)
Defined as change of the largest diameter of target BCC
Immune responses
时间窗: After 6 vaccinations with IO103 (10 weeks)
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)
次要结局
- Immune responses in skin(After 6 vaccinations with IO103 (10 weeks))
- Incidence of treatment emergent adverse events (safety and tolerability)(From the time that the subject provides written informed consent and throughout the trial duration, until 30 days post last dose of trial treatment)
