Clinical Trial Summary

The purpose of this study is to determine the safety and bioactivity of Euphorbia kansui, which has been used in traditional Chinese medicine for the treatment of edema, ascites, and asthma. The investigators previously reported that effective fractions from the dichloromethane extracts of the roots of Euphorbia kansui can reactivate latent HIV-1 replication in different latent cells (The 24th China science technology Forum-High level Forum on HIV cure, December 16-17, 2012, Beijing). Importantly, in resting CD4+ T cells of HIV-1-infected patients on suppressive antiretroviral therapy (ART), it could effectively induce ex vivo latent HIV-1 expression. Sera from rats receiving orally administered effective fractions were able to reactivate latent HIV-1. The investigators also found a substantially potent ingenol derivative EK-16A, EK-1A, EK-5A, EK-15A from Euphorbia kansui and proved that it was potent in reversing HIV-1 latency. The investigators' hypothesis is that Euphorbia kansui Pill will be safe and well-tolerated and at the doses administered, increase HIV transcription in latently-infected cells among HIV-infected patients on suppressive antiretroviral therapy.

Description:

Every participant will receive oral Euphorbia kansui Pill every day. The dose of Euphorbia kansui will be 1g each time for 7 consecutive days. All participants will keep their antiretroviral therapy during this study.

Each step of this study will last for 21 days, involving 7 study visits (Screening,Day 0, 1, 3, 5, 7, 14, 21) for every participant. At the screening visit, participants will give a medical history and will undergo a physical exam; blood samples will be collected. Participants will undergo pharmacodynamic sampling which will require that blood be collected 12 hours after kansui Pill administration on Day 1, 3, 5,7. If participants agree, their blood samples may be stored for future research.

10. CD4 T cells isolated in vitro and stimulated with kansui, and the kansui activation test is positive.

11. All volunteers must agree not to participate in a conception process.

12. Must have adequate organ function as indicated by the following lab values:

Hematological: Absolute Neutrophil Count (ANC) = 1,500/mcL Platelets = 125,000/mcL Hgb = 12 g/dL Coagulation: Prothrombin Time or International Normalized Ratio (INR) = 1.5x upper limit of normal (ULN) Chemistry: K+ levels Within normal limits Mg++ levels > Lower limits of normal (LLN) but <1.5 x ULN Glucose Screening serum glucose(fasting/non-fasting) below 120 mg/dl.
