HIV Drugs Show Promise as First Prophylactic Treatment for HTLV-1 Virus in Landmark Australian Study
- Australian researchers have identified the first potential prophylactic treatment for HTLV-1, a neglected virus affecting 10 million people globally, using existing HIV antivirals tenofovir and dolutegravir in humanized mouse models.
- The study marks the first time any research group has successfully suppressed HTLV-1 transmission in a living organism, with both drugs showing powerful suppression against international and Australian virus strains.
- Combination therapy using HIV antivirals with MCL-1 protein inhibitors demonstrated the ability to selectively kill HTLV-1-infected cells, suggesting a potential curative strategy for established infections.
- The research team is now in discussions with pharmaceutical companies to include HTLV-1 patients in ongoing HIV drug clinical trials, potentially leading to the first approved pre-exposure prophylaxis for this life-threatening virus.
