MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Immune checkpoint inhibitors (ICI) that have seen success in the treatment of patients with various tumour types have not been as effective in patients with metastatic pancreatic cancer and therefore immune-therapeutic agents of novel mechanism of action, in particular in combination with existing ICI, need to be investigated.
This study set out to test the safety and efficacy of pixatimod, a novel immunomodulatory agent, in combination with nivolumab, firstly in the dose escalation cohorts in patients with any solid tumour for the maximal tolerable dose, and then using this dose to further treat an expansion cohort of patients with pancreatic cancer. Altogether 16 patients had received the combination and in 10 patients in whom treatment response was evaluable, 4 patients experienced a clinical benefit and continued treatment in the trial, with 1 patient having a significant partial response now treated for 48 weeks. Interestingly, all these 4 patients had metastatic colorectal cancer. Side effect profile has been consistent with other immunotherapeutic agent combination and in the patients who had clinical benefit, no treatment related side effects were observed. Continue reading
