Primary Objectives

1.Evaluation of safety and tolerability after repeated administration of injectable Lipivirtide in HIV-infected patients not receiving antiretroviral therapy

Secondary Objectives

1. Evaluation of the pharmacokinetic properties of injectable Lipovirtide after multiple administrations in HIV-infected patients not receiving antiretroviral therapy, to obtain pharmacokinetic parameters.
2. Evaluation of the efficacy of injectable Lipovirtide for HIV in HIV-infected patients not receiving antiretroviral therapy.
3. Evaluation of the immunogenicity of lipovirtide for injection.

PK parameters were calculated by Phoenix WinNonlin 8.2 (or higher) and other data were analyzed using SAS 9.4 (or higher) software.

Full analysis set: will be used for efficacy analysis. Descriptive statistics of HIV viral load and CD4+ T-cell count at each time point, calculation of subject means, standard deviations, quartiles, minimum and maximum values, and comparison of changes from baseline at each time point.

Safety analysis set: calculation of the incidence of adverse events and systematic categorization. Calculate the incidence of adverse events and systematically categorize them. Cross tabulation of clinical determination before and after drug administration for laboratory tests, ECG tests, and physical examination. Changes in measured values of vital signs over time. The actual measured values of the vital signs varied over time.

Immunogenicity analysis: statistics of the results of each indicators (including the positive incidence and titer) over time, and a detailed list of the results of each visit.

Pharmacokinetic analysis: individual and mean c-t curves were plotted; mean, standard deviation, interquartile, maximum, minimum and coefficient of variation of blood concentrations at each time point were listed. Pharmacokinetic parameters were calculated for each subject from the non-compartment model. and the arithmetic mean, standard deviation, quartiles, maximum value, minimum value and geometric mean and coefficient of variation were also calculated for each parameter.

Inclusion Criteria:

1. 18~60 years old (including the critical value), male and female are not limited.
2. Body mass index BMI [weight (kg)/height2 (m2)] is 18.0~28.0 (including the critical value), male weight should be ≥50kg, female weight should be ≥45kg.
3. Diagnosed with HIV-1 infection.
4. Those who did not plan to have children within 2 weeks prior to screening and within 3 months after the end of the trial and who agreed to use effective non-pharmacological contraception during the trial.
5. Subjects should fully understand the purpose, nature and methods of the test and the possible adverse effects and voluntarily participate in this test.
