Tenofovir exalidex is consistently >300-fold more active than Tenofovir against multiple viruses in several different cell systems. Tenofovir exalidex will be effective against MNR mutants, including those that are unresponsive to all currently available NRTIs. Notably, the average EC50 in PBMCs for CMX157 against a panel of 27 wild-type HIV-1 isolates representing group M subtypes A to G and group O was 2.6 nM (range, 0.2 to 7.2 nM)[1].
Tenofovir exalidex exerts its therapeutic actions by inhibiting HBV polymerase-mediated HBV DNA elongation, but there is no known binding of cyclophilins to HBV polymerase nor participation of cyclophilins in DNA elongation. The combinational effect of CRV431 (host-targeting) and Tenofovir exalidex (direct-acting) on HBV DNA production is more consistent with the two compounds acting on distinct steps of the HBV life cycle[3].
Tenofovir exalidex (Sprague-Dawley rats) is orally available and has no apparent toxicity when given orally to rats for 7 days at doses of 10, 30, or 100 mg/kg/day[2].Tenofovir exalidex (5-10 mg/kg; oral gavage; daily for a period of 16 days) decreases liver HBV DNA levels dose-dependently[3].
