Molecular Formula:
Molecular Weight:
NOV-002 is a stabilized formulation of disodium glutathione disulfide (GSSG; oxidized glutathione) and cisplatin (1000:1) with potential chemoprotective and immunomodulating activities. Mimicking endogenous GSSG, glutathione disulfide NOV-002 acts as a competitive substrate for gamma-glutamyl-transpeptidase (GGT), which may result in the S-glutathionylation of proteins, predominantly actin, a redox stress on endoplasmic reticulum (ER), and ER stress-induced apoptosis; S-glutathionylation may be stimulated by reactive oxygen species (ROS) liberated by a glutathione disulfide NOV-002-induced increase in GGT activity. Glutathione disulfide NOV-002 may also induce phosphorylation of proteins such as ERK and p38, two kinases that play critical regulatory roles in cell proliferation and apoptosis. The cisplatin component of this agent does not provide an effective therapeutic concentration of cisplatin in vivo.

1.Protective effects of a glutathione disulfide mimetic (NOV-002) against cisplatin induced kidney toxicity.
Jenderny S1, Lin H, Garrett T, Tew KD, Townsend DM. Biomed Pharmacother. 2010 Jan;64(1):73-6. doi: 10.1016/j.biopha.2009.09.009. Epub 2009 Oct 17.
NOV-002 is a glutathione disulfide (GSSG) mimetic with chemoprotective activity. Previous and ongoing clinical studies demonstrate a significantly improved 1-year survival and decreased tumor progression rates in non-small cell lung (NSCLC) and ovarian cancer patients when NOV-002 was included in cisplatin containing regimens. In order to understand this chemoprotective property, we employed as an animal model of kidney toxicity, 8-week-old Bl6 mice that were treated with a single nephrotoxic dose of cisplatin (15 mg/kg, ip) and sacrificed on Day 5. One group of animals was treated with NOV-002 (15 mg/kg, im) daily. NOV-002-treated mice had significantly lower levels of plasma creatinine compared to mice treated with cisplatin alone (4.7 vs 2.9 mg/dL, respectively). Moreover, NOV-002 protected the kidneys from cisplatin mediated proximal tubule damage, including dilation of tubules and the presence of protein casts. Since cisplatin-induced nephrotoxicity can be mediated by a glutathione-platinum conjugate catalyzed by gamma-glutamyl-transpeptidase (GGT) and glutathione is an endogenous substrate of GGT, the protective effect of NOV-002 in the kidney may be attributed to its ability to act as a competitive substrate for the enzyme.
2.Phase 2 study of neoadjuvant treatment with NOV-002 in combination with doxorubicin and cyclophosphamide followed by docetaxel in patients with HER-2 negative clinical stage II-IIIc breast cancer.

NOV-002 (a formulation of disodium glutathione disulfide) modulates signaling pathways involved in tumor cell proliferation and metastasis and enhances anti-tumor immune responsiveness in tumor models. The addition of NOV-002 to chemotherapy has been shown to increase anti-tumor efficacy in animal models and some early phase oncology trials. We evaluated the clinical effects of NOV-002 in primary breast cancer, whether adding NOV-002 to standard preoperative chemotherapy increased pathologic complete response rates (pCR) at surgery, and determined whether NOV-002 mitigated hematologic toxicities of chemotherapy and whether levels of myeloid derived suppressor cells (MDSC) were predictive of response. Forty-one women with newly diagnosed stages II-IIIc HER-2 negative breast cancer received doxorubicin-cyclophosphamide followed by docetaxel (AC → T) every 3 weeks and concurrent daily NOV-002 injections. The trial was powered to detect a doubling of pCR rate from 16 to 32% with NOV-002 plus AC → T (α = 0.
3.Letter to the editor regarding the article by Jenderny et al.
Sönmez MF, Savranlar Y. Biomed Pharmacother. 2011 Aug;65(5):385. doi: 10.1016/j.biopha.2011.04.002. Epub 2011 Jun 28.
Jenderny et al. demonstrated that NOV-002 treatment may be protected by cisplatin-induced nephrotoxicity. However, Jenderny's article has some errors. These mistakes are checked and corrected.
4.The glutathione disulfide mimetic NOV-002 inhibits cyclophosphamide-induced hematopoietic and immune suppression by reducing oxidative stress.
Diaz-Montero CM1, Wang Y, Shao L, Feng W, Zidan AA, Pazoles CJ, Montero AJ, Zhou D. Free Radic Biol Med. 2012 May 1;52(9):1560-8. doi: 10.1016/j.freeradbiomed.2012.02.007. Epub 2012 Feb 15.
The oxidized glutathione mimetic NOV-002 is a unique anti-tumor agent that not only has the ability to inhibit tumor cell proliferation, survival, and invasion, but in some settings can also ameliorate cytotoxic chemotherapy-induced hematopoietic and immune suppression. However, the mechanisms by which NOV-002 protects the hematopoietic and immune systems against the cytotoxic effects of chemotherapy are not known. Therefore, in this study we investigated the mechanisms of action of NOV-002 using a mouse model in which hematopoietic and immune suppression was induced by cyclophosphamide (CTX) treatment. We found that NOV-002 treatment in a clinically comparable dose regimen attenuated CTX-induced reduction in bone marrow hematopoietic stem and progenitor cells (HSPCs) and reversed the immunosuppressive activity of myeloid-derived suppressor cells (MDSCs), which led to a significant improvement in hematopoietic and immune functions. These effects of NOV-002 may be attributable to its ability to modulate cellular redox.
