Crossref PubMed ISI Google Scholar; 51. Melanoma is a serious form of skin cancer that arises from a particular skin cell type called a melanocyte. In cancer patients with solid tumors, tilsotolimod is injected directly into a tumor to trigger TLR9 into action and prime a local immune response to help attack the tumor. TLR9 agonist SD-101 may stimulate the immune system in different ways and stop cancer cells from growing. These results were first presented as a poster at the American Society of Clinical Oncology (ASCO) in 201591 and have been featured in several peer-reviewed journal articles.

Alzheimer’s disease (AD) is the most common cause of dementia, and currently, there is no effective treatment. This has been demonstrated in pre-clinical models, and our translational studies during early clinical trials have shown rapid immune activation in the injected tumor along. TLR9 agonists have been shown to be most effective when injected directly into a tumor, says Monica Wallter. The interim data of two phase 3 trials of PF-3512676 (formerly called CpG 2006) showed that it failed to improve the clinical outcomes compared to chemotherapy alone [2]. 92,93 In this Phase II study, nine. 15 Poly(I:C.
