The development of a safe, effective, and affordable combination microbicide to prevent the sexual transmission of HIV combination is urgently needed. Our previous studies demonstrated that 3-hydroxyphthalic anhydride-modified chicken ovalbumin (HP-OVA) exhibited potent antiviral activity against a broad spectrum of HIV, simian immunodeficiency virus (SIV) and herpes simplex virus (HSV), making it a promising candidate as a component of combination microbicide. Here we intended to evaluate potential synergistic anti-HIV-1 effect of HP-OVA in combinations with antiretroviral drug (ARV)-based microbicide candidates. The antiviral activity of HP-OVA and the ARVs, including HIV-1 entry inhibitors (T20, C52L, NB64, NBD556, AMD3100 and Maraviroc) and reverse transcriptase inhibitors (Tenofovir, UC781 and TMC120), tested alone or in combination, against HIV-1 X4 and R5 viruses, including some drug-resistant strains, was determined in MT-2 and peripheral blood mononuclear cells using p24 assay. The immune responses induced by HP-OVA that was applied in the vaginas of rats were detected by ELISA. When each of these ARV-based microbicide candidates was combined with HP-OVA, synergistic activity was observed against infection by both X4 and R5 strains, and the degree of synergy differed in each case. HP-OVA was highly effective against several ARV-resistant HIV-1 strains, suggesting that combining HP-OVA with these ARV-based microbicide candidates might work cooperatively against both drug-sensitive and resistant HIV-1 strains. Human body fluids and human proteins had little or no effects on HP-OVA-mediated inhibitory activity against HIV-1 infection. HP-OVA formulated in the universal gel maintained its antiviral activity for at least one month and only induced weak immune responses after its multiple applications in the vaginas of rats. Synergistic and complementary effects against infection by a broad spectrum of HIV-1 strains were observed by combining HP-OVA with the ARV-based microbicide candidates. These findings provide a sound scientific platform for the development of a safe, effective and affordable combination microbicide to prevent the sexual transmission of HIV and other sexually transmissible viruses.
