Foscenvivint in HIV/HCV co-infected adults with liver cirrhosis and hemophilia
Official title: A Multicenter, Single-Arm, Open-Label Phase 2 Study of Once-Weekly Foscenvivint in Patients With Liver Cirrhosis Due to HIV/HCV Co-infection in the Setting of Hemophilia
Run by Komagome Hospital · NCT07681089 · Data updated 2026-11-12
This study tests whether foscenvivint can help people with liver cirrhosis due to HIV/HCV co-infection who also have hemophilia.

Is this trial a fit for you?
✓Likely a good fit
Adults with hemophilia and liver cirrhosis due to HIV/HCV co-infection, with HIV RNA <200 copies/mL and CD4 ≥200 at screening, SVR for HCV ≥12 months, Child-Pugh class A or B cirrhosis, and evidence of cirrhosis by FibroScan or imaging.
✕Probably not a fit
Patients without cirrhosis progression or those with more advanced liver disease or uncontrolled HIV may not benefit from this therapy.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is a multicenter, single-arm Phase 2 trial evaluating weekly intravenous foscenvivint over 24 weeks in adults with Child-Pugh A-B liver cirrhosis caused by HIV/HCV co-infection and hemophilia. Eligible participants must have controlled HIV, prior SVR to HCV, and evidence of cirrhosis, then receive follow-up at 4 weeks after the last dose. The study will monitor safety and preliminary efficacy, with ongoing assessments during treatment and after completion. Results will inform whether this approach merits further investigation in this specific comorbidity profile.
Why it matters
Potential benefit: If successful, participants may experience improvements in liver function or disease markers and gain access to a potentially beneficial therapy tailored for this complex co-morbidity.
How similar studies have gone: Prior similar liver-directed therapies in complex co-infection populations have shown mixed results; this trial explores a novel agent in a niche subset.

Inclusion Criteria:
* Patients with hemophilia and liver cirrhosis caused by HIV/HCV co-infection who meet both of the following criteria:
1. Patients who are serum HIV-RNA positive or HIV antibody positive, with HIV-RNA maintained at \<200 copies/mL and a CD4-positive T lymphocyte count of ≥200 cells/µL at screening.
2. Patients with HCV infection who have achieved sustained virologic response (SVR) at least 12 months before registration.
* Patients with Child-Pugh class A or B liver cirrhosis (Child-Pugh score 5-9).
* Patients who meet at least one of the following criteria for the diagnosis of liver cirrhosis:
<!-- -->
1. Liver stiffness measurement by FibroScan of ≥12.5 kPa, corresponding to fibrosis stage F4, at screening.
2. Abdominal CT showing changes in liver morphology and/or findings suggestive of portal hypertension.
* Patients with an Eastern Cooperative Oncology Group Performance Status of 0-2.
Exclusion Criteria:
* Patients with liver cirrhosis caused by etiologies other than HCV or of unknown etiology.
* Patients with esophageal or gastric varices judged by endoscopic examination at screening to require treatment.
* Patients with current malignancy or a history of malignancy within 3 years before registration.
* Patients who have undergone liver transplantation or other organ transplantation, including bone marrow transplantation.
* Patients with active AIDS-defining disease requiring treatment. -
