MedKoo Cat#: 200776 | Name: CHS-828
Featured New

Description:

WARNING: This product is for research use only, not for human or veterinary use.

CHS-828, also known as GMX-1778, is a potent and selective NAMPT inhibitor. CHS-828 inhibits cellular synthesis of NAD. CHS 828 kill tumour cells by inhibiting the nuclear factor-kappaB translocation but unlikely through down-regulation of proteasome. CHS 828 has shown promising anticancer activity in experimental tumor models and primary cultures of cancer cells from patients. CHS 828 showed a synergistic effect with melphalan in 67%, doxorubicin in 47%, etoposide in 38% and Ara-C in 14% of AML samples.

    Review of Phase I trials of CHS-828. Seven patients with previously treated solid tumours received oral administration of CHS 828 in the dose range 20-80 mg once weekly for 3 weeks in 4 weeks cycles. Toxicity was dominated by gastrointestinal symptoms including nausea, vomiting, diarrhoea, constipation, subileus and gastric ulcer. One patient had thrombocytopenia grade 2. There were two cases each of grade 3-4 hyperuricemia and hypokalemia. Safety and efficacy of the NAD depleting drugs CHS 828 and FK866 have been reported from four phase I clinical trials, including a total of 97 patients with previously treated solid tumours. Outstanding toxicity reported was thrombocytopenia and various gastrointestinal symptoms. No objective tumour remission has been observed in the total of 104 patients treated in the above early trials. Critical toxicity from NAD depleting cancer drugs to consider in future trials seems to be thrombocytopenia and various gastrointestinal symptoms. Efficacy of NAD depleting drugs when used alone is expected to be low. (source: Cancer Chemother Pharmacol. 2010 May;65(6):1165-72 ).   Phase I study of CHS-828. CHS 828 was given orally once every 3 weeks. The starting dose was 50 mg, which was escalated to 500 mg. A total of 107 courses was administered to 37 patients. At the 500-mg dose level, two of three patients experienced dose-limiting toxicities (DLT) (grade 3 mucositis and grade 4 thrombocytopenia), establishing this as the MTD. One of seven patients treated at 420 mg dose experienced DLT (grade 4 leucopenia, grade 4 mucositis and grade 4 diarrhoea), and this was considered the recommended dose for phase II studies. Vomiting, haematuria, leucopenia and thrombocytopenia were other significant toxicities. The pharmacokinetics of CHS 828 showed large variations both between and within patients. No objective responses were seen. A dose of 420 mg of CHS 828 administered every 3 weeks is the recommended dose, while 500 mg is the MTD. (source: Eur J Cancer. 2005 Mar;41(5):702-7.). Phase I study of CHS-828. (source: Eur J Cancer. 2005 Mar;41(5):702-7.).    
Biological target:
CHS-828 (GMX1778) is a competitive inhibitor of nicotinamide phosphoribosyltransferase (NAMPT), with an IC50 less than 25 nM.
In vitro activity:
In this report, GMX1778 induces ROS, specifically superoxide radicals evidenced by DHE oxidation, via decreasing the cellular level of NAD+, NADP+, NADH, and NADPH. The results measuring apoptosis by annexin V staining after treatment with GMX1778 in the cell lines tested are consistent with the dual roles of p53 in response to ROS. In addition to p53, the induced ROS levels by GMX1778 were further suppressed when the NAD+ levels were restored by exogenously adding niacin to NAPRT1-expressing cancer cells tested. Notably, the ROS were not induced by GMX1778 within 48 h of post-GMX1778 exposure in normal (HMEC) or immortalized cells (MCF10A) tested in the absence of NA.

In vivo activity:
Four days after intratumoral injection of GMX1778 MP (microparticles), there was a significant increase in the number of PD-L1-positive cells within GL261 tumors as compared to two controls, PBS and blank MP not containing drug (Fig. 2B, C). Co-immunofluorescence of PD-L1 and glioma marker nestin or macrophage marker Arg1 showed that upregulation of PD-L1 occurred in both GBM cells and glioma-infiltrating macrophages (Fig. 2D, E). Thus, local MP delivery of NAMPT inhibitor induces upregulation of immune checkpoint PD-L1 in murine GBM.
