Efficacy and Safety of Immune Checkpoint Inhibitors for Refractory Opportunistic Infections in AIDS
A Study on the Efficacy and Safety of Immune Checkpoint Inhibitors in the Treatment of AIDS Complicated With Refractory Opportunistic Infections
This prospective, single-arm, open-label study aims to evaluate the efficacy and safety of a PD-1 inhibitor (Sintilimab) combined with standard anti-infective therapy in patients with advanced HIV disease (AHD) who are suffering from refractory opportunistic infections (OIs).
Despite effective antiretroviral therapy (ART), some HIV patients develop severe, hard-to-treat infections (such as CMV, PCP, Tuberculosis, etc.) that do not respond to standard antimicrobial treatments. This is often due to a condition called "immune exhaustion," where the body's infection-fighting T-cells become inactive and express high levels of a protein called PD-1.
Sintilimab is an immune checkpoint inhibitor that blocks PD-1, effectively "waking up" the exhausted T-cells. While traditionally used for cancer, recent evidence suggests it can safely restore the immune system's ability to clear stubborn infections in HIV patients. In this study, eligible patients with refractory OIs and evidence of immune exhaustion will receive Sintilimab (200 mg intravenously every 3 weeks for a total of 3 doses) alongside their regular treatments. Researchers will monitor patient safety, clinical improvement, and immunological recovery.

설명
Inclusion Criteria:
Age ≥ 18 years. Confirmed HIV-1 infection.
Must have at least one opportunistic infection meeting the "refractory" criteria after currently available standard anti-infective treatment, defined as follows:
- Parvovirus B19: Hemoglobin (Hb) fails to recover (increase <10g/L) or requires transfusion maintenance, with reticulocytes persistently <1% after 4 weeks of Intravenous Immunoglobulin (IVIG) therapy.
- Cytomegalovirus (CMV): Blood/body fluid CMV-DNA decrease <1 log10 or new/worsening organ damage after 2 weeks of Ganciclovir or Foscarnet therapy.
- Mpox virus: Unhealed lesions, new lesions, necrotic coalescence, or no decrease in viral load after 14 days of Tecovirimat, Cidofovir, or Brincidofovir therapy.
- Progressive Multifocal Leukoencephalopathy (PML): Continuous deterioration of neurological symptoms or expanded lesion area on MRI after 3 months of optimized antiretroviral therapy (ART).
- Pneumocystis jirovecii pneumonia (PCP): No improvement in oxygenation index or expanded radiological lesions after 8 days of adequate SMZ-TMP therapy.
- Cryptococcal meningitis: Persistently positive cerebrospinal fluid (CSF) culture after 4 weeks of induction therapy.
- Talaromyces marneffei / Invasive Aspergillosis: Persistently positive culture or progression of radiological/clinical symptoms after 2 weeks of Amphotericin B or Voriconazole therapy.
- Mycobacterium tuberculosis (TB): Persistently positive sputum smear or culture after 2 months of standard anti-tuberculosis therapy.
- Nontuberculous mycobacteria (NTM): No improvement in clinical symptoms after 1 month of standard therapy, or culture not turning negative after 3 months.
High PD-1 expression on peripheral CD8+ T cells (>25%) OR weak pathogen-specific ELISpot response (<50 SFCs/10^6 cells).
Agreement to use highly effective contraception during the study and for 6 months after the end of the trial.
Voluntary signing of informed consent.
Exclusion Criteria:
History of active autoimmune disease or autoimmune disease requiring systemic treatment.
Prior organ transplantation or hematopoietic stem cell transplantation. Pregnant or lactating women. Known allergy or anti-drug antibodies to the study drug or its excipients. Prior treatment or exposure to any other immune checkpoint inhibitors. Received immunomodulatory or immunosuppressive therapy (excluding glucocorticoids) within 24 weeks prior to the first dose of the study drug.
Psychiatric disorders or substance abuse that may interfere with the trial. Other severe medical conditions deemed by the investigator as unsuitable for trial participation (e.g., uncontrolled severe heart, liver, or renal failure).
