Peptide vaccination directed against IDO1-expressing immune cells elicits CD8 + and CD4 + T-cell-mediated antitumor immunity and enhanced anti-PD1 responses
16 views | Sep 17 2020
Souvik Dey et al. found that the in vivo antitumor effects demonstrated with IDO1-based vaccines via targeting of the tumor microenvironment highlighted the utility of mouse models for further exploration and refinement of this novel vaccine-based approach to IDO1-directed cancer therapy and its potential to improve patient response rates to anti-PD1 therapy.

Sean Hacking et al. supported the theoretical foundation for targeting PD-L1 and IDO-1 in CRC, which now needed verification in well-designed robust clinical trials. [Read the Full Post]
MYC promotes tryptophan uptake and metabolism by the kynurenine pathway in colon cancer
176 views | Jan 17 2020
Venkateswaran N et al. proposed that limiting cellular kynurenine or its downstream targets could present a new strategy to reduce the proliferation of MYC-dependent cancer cells. [Read the Full Post]
First-in-Human Phase I Study of the Oral Inhibitor of Indoleamine 2,3-Dioxygenase-1 Epacadostat (INCB024360) in Patients with Advanced Solid Malignancies
175 views | Nov 25 2019
Beatty GL et al. showed that epacadostat was generally well tolerated, effectively normalized kynurenine levels, and produced maximal inhibition of IDO1 activity at doses of ≥100 mg BID. Studies investigating epacadostat in combination with other immunomodulatory drugs are ongoing. [Read the Full Post]
Updates in the Clinical Development of Epacadostat and Other Indoleamine 2,3-Dioxygenase 1 Inhibitors (IDO1) for Human Cancers
180 views | Nov 24 2019
Komiya T et al. indicated that IDO1 is a promising target that can improve the treatment outcome in the field of Immuno-oncology. Several orally available IDO1 inhibitors including Epacadostat have entered human clinical trials over the last few years without a major safety concern. Although there is no objective response in single-agent trials, combination regimens with PD-1 inhibitors appear to exceed the activity of PD-1 inhibitors alone. Recent phase III ECHO 301 trial testing the combination of Epacadostat with Pembrolizumab in melanoma did not show superior outcome compared to Pembrolizumab alone. This lead to halting of other phase III trials using IDO1 inhibitors. In this minireview, we will discuss the recent clinical development of Epacadostat and other IDO1 inhibitors.

Effects of EF-24, RAD001, and paclitaxel on the expression profiles of apoptotic and anti-apoptotic genes
385 views | May 15 2019
Alp E et al. showed that response of these cells to paclitaxel, EF-24, and RAD001 was found different at the transcriptional level of apoptotic and antiapoptotic genes. [Read the Full Post]
Effects of Epacadostat on Brain Extracellular Fluid Concentrations of Serotonin -- An Intracerebral Microdialysis Study in Sprague-Dawley Rats
324 views | May 14 2019
Zhang Y et al. suggested that serotonin syndrome is unlikely following treatment with either epacadostat alone or with combination with MAOIs such as linezolid. [Read the Full Post]
