| Description | Merimepodib is a novel noncompetitive inhibitor of IMPDH (Inosine monophosphate dehydrogenase).In Vitro:VX-497 has antiproliferative effect on lymphoid and keratinocyte cells. The antiproliferative effect of VX-497 in cells is reversed within 48 h of its removal[1]. VX-497 has intermediate antiviral activity against a second group of viruses, which includes HSV-1, parainfluenza-3 virus, BVDV, VEEV, and dengue virus, with IC50s ranging from 6 to 19 μM. VX-497 is 100-fold more potent, with an IC50 of 380 nM and a corresponding CC50 of 5.2 μM, for a therapeutic index of 14. The antiviral activity of VX-497 in HepG2.2.2.15 cells is reversed threefold by the addition of guanosine[2].In Vivo:Oral administration of VX-497 inhibits the primary IgM antibody response in a dose-dependent manner, with an ED50 value of appr 30-35 mg/kg in mice. Single daily dosing of VX-497 is observed to be as effective as twice-daily dosing in this model of immune activation[1]. GVHD developed in the vehicle-treated allografted F1 mice and treatment with VX-497 improved all manifestations of the disease significantly. The 2.9-fold increase in spleen weight in allografted animals is reduced to a 1.6-fold increase in the VX-497-treated mice. Serum IFN-gamma levels are increased 54-fold in the vehicle group while there is a 7.4-fold increase in VX-497-treated animals[3]. References: | |||||

Merimepodib, pegylated interferon, and ribavirin in genotype 1 chronic hepatitis C pegylated interferon and ribavirin nonresponders.[Pubmed:19852040]
Hepatology. 2009 Dec;50(6):1719-26.
UNLABELLED: Merimepodib (MMPD) is an orally administered, inosine monophosphate dehydrogenase inhibitor that has shown antiviral activity in nonresponders with chronic hepatitis C (CHC) when combined with pegylated interferon alfa 2a (Peg-IFN-alfa-2a) and ribavirin (RBV). We conducted a randomized, double-blind, multicenter, phase 2b study to evaluate the antiviral activity, safety, and tolerability of MMPD in combination with Peg-IFN-alfa-2a and RBV in patients with genotype 1 CHC who were nonresponders to prior therapy with Peg-IFN and RBV. Patients received 50 mg MMPD, 100 mg MMPD, or placebo every 12 hours, in addition to Peg-IFN-alfa-2a and RBV, for 24 weeks. Patients with a 2-log or more decrease from baseline or undetectable hepatitis C virus (HCV) RNA levels at week 24 were then eligible to continue Peg-IFN-alfa-2a and RBV for a further 24 weeks, followed by 24 weeks of follow-up. The primary efficacy endpoint was sustained virological response (SVR) rate at week 72 in all randomized patients who received at least one dose of study drug and had a history of nonresponse to standard therapy. A total of 354 patients were randomized to treatment (117 to placebo; 119 to 50 mg MMPD; 118 to 100 mg MMPD), and 286 completed the core study. The proportion of patients who achieved SVR was similar among the treatment groups: 6% (6/107) for 50 mg MMPD, 4% (5/112) for 100 mg MMPD, and 5% (5/104) for placebo (P = 0.8431). Adverse-event profiles for the MMPD combination groups were similar to that for Peg-IFN-alfa and RBV alone. Nausea, arthralgia, cough, dyspnea, neutropenia, and anemia were more common in patients taking MMPD. CONCLUSION: The addition of MMPD to Peg-IFN-alfa-2a and RBV combination therapy did not increase the proportion of nonresponder patients with genotype 1 CHC achieving an SVR.
A randomized, double-blind, placebo-controlled dose-escalation trial of merimepodib (VX-497) and interferon-alpha in previously untreated patients with chronic hepatitis C.[Pubmed:16152757]
Antivir Ther. 2005;10(5):635-43.
Inhibition of inosine monophosphate dehydrogenase (IMPDH) is one of several proposed mechanisms of action for ribavirin (RBV), a critical component of the current treatment for chronic hepatitis C (CHC). This study was a double-blind, placebo-controlled dose-escalation study of a novel, selective, orally active small molecule inhibitor of IMPDH, Merimepodib (VX-497 or MMPD) in combination with standard interferon-alpha (IFN-alpha). Fifty-four treatment-naive patients with genotype-1 CHC were randomized to receive IFN-alpha 3 MIU subcutaneously three times a week, alone or in combination with 100 mg or 300 mg (every 8 h) of MMPD for 4 weeks. At the end of 4 weeks, all patients were offered 48 weeks of treatment with IFN-alpha/RBV. The objectives of the study were to evaluate the tolerability of the IFN-alpha/MMPD combination and to evaluate whether MMPD had an on-treatment effect on HCV-RNA, similar to RBV when added to IFN-alpha. The drug combination was generally well tolerated; one patient at the higher dose discontinued because of elevated alanine aminotransferase levels. No pharmacokinetic interactions were evident between the two drugs. Analysis of covariance that adjusted for a baseline imbalance in HCV-RNA in the intent-to-treat population did not show any significant differences between the treatment groups, or between MMPD plus IFN-alpha compared with IFN-alpha alone. However, the per-protocol primary efficacy analysis based on treatment-compliant patients demonstrated a greater reduction in mean HCV-RNA in the combination of 100 mg MMPD plus IFN-alpha compared with IFN-alpha alone (-1.78 log vs -0.86 log, P=0.037). In conclusion, the addition of a selective IMPDH inhibitor to IFN-alpha was well tolerated. In a low-dose range, the addition of MMPD may have the potential to add to the antiviral efficacy of IFN-alpha. Larger, longer duration trials incorporating pegylated IFN would be required to determine whether this combination, alone or with RBV, would increase either early or sustained virological response rates.
Phase 2 study of the combination of merimepodib with peginterferon-alpha2b, and ribavirin in nonresponders to previous therapy for chronic hepatitis C.[Pubmed:17629590]
J Hepatol. 2007 Oct;47(4):476-83.
BACKGROUND/AIMS: While combination of peginterferon-alpha (PEG-IFN) and ribavirin (RBV) therapy is the current standard of care for chronic hepatitis C (CHC), only 44-51% of genotype-1 patients achieve a sustained virological response (SVR), and both agents produce treatment-limiting toxicities. In the hepatitis C virus (HCV) replicon system, Merimepodib (MMPD), a novel, selective inhibitor of inosine monophosphate dehydrogenase, has shown potent antiviral effects. METHODS: This randomized, placebo-controlled, double-blind study evaluated the safety and antiviral activity of PEG-IFN-alpha2b and RBV combined with either placebo, 25mg MMPD every 12h (q12h), or 50mg MMPD q12h in interferon-alpha (IFN) and RBV nonresponders. After 24 weeks of treatment, subjects with undetectable HCV RNA were proposed to continue assigned treatment for up to 24 additional weeks. RESULTS: The PEG-IFN-alpha, RBV, and MMPD combination was well tolerated at both doses. After 24 weeks, the proportion of HCV RNA undetectable subjects was 8/11 (73%) in the 50-mg MMPD group, 2/10 (20%) in the 25-mg MMPD group, and 3/10 (30%) in the placebo group (P=0.02, Jonckheere-Terpstra test for increasing dose response). Ten subjects entered and completed an extension study, at Week 48, 2 of 2 (100%) of the 25-mg and 3 of 5 (60%) of the 50-mg subjects remained HCV RNA undetectable, compared with 3 of 3 (100%) of the placebo subjects. At Follow-up Week 24, 2 (100%) of the 25-mg , and 1 (25%) of the 50-mg subjects remained undetectable, compared with 1 (33%) of the placebo subjects. Pharmacokinetic and pharmacodynamic analyses showed a correlation between MMPD exposure and early virological response at week 12, but not with hemoglobin decreases often associated with RBV. CONCLUSIONS: In conclusion, PEG-IFN-alpha2b and RBV combined with 50 mg MMPD q12h was well tolerated and induced virological response with undetectable HCV RNA in IFN-alpha and RBV nonresponders.
