Viriom Presented the Results of VM-1500A-LAI Studies on International HIV Conference in Hong Kong

In June 28–30, Viriom Company of High-Tech ChemRar Centre, a resident of biomedicine technologies cluster of Skolkovo Foundation, presented the results of pre-clinical studies of VM-1500A-LAI drug at the International Asian-Pacific Conference on HIV infection in Hong Kong (APACC 2018).
This is a long-acting injection formulation of active elsulfavirin component, a new generation non-nucleoside reverse transcriptase inhibitor (NNRTI) which is characterized by increased resistance barrier and the absence of cross-resistance with the other NNRTIs. The drug was authorized in 2017 in Russia as oral capsules under the brand name ELPIDA®.
After oral administration, Elsulfavirin (pro-drug) is rapidly metabolized in liver into the active metabolite, VM-1500A, which has a long half-life (7–9 days) due to a temporary VM-1500A deposit in erythrocytes with following slow plasma release and impact on target cells, i.e. virus-containing lymphocytes. Particular VM-1500A pharmacokinetic profile served as a basis for the development of innovative prolonged drug formulations with monthly dosing regimen, which can be used as a supportive HIV therapy increasing patients’ adherence to the therapy.
The study results presented at the conference (findings on pharmacokinetics of aqueous elsulfavirin/VM1500A nanosuspensions in blood plasma and in erythrocytes) confirm the possibility of long-term maintenance of active drug concentration in blood (for 1 month and longer).
VM-1500A-LAI development project is performed with the support of the Skolkovo Foundation. In the near future, it is planned to launch a phase I clinical study in healthy volunteers.
