About this study

Official title: A Pilot/Feasibility Study of Ledipasvir/Sofosbuvir as Treatment for Hepatitis C in Hematopoietic Cell Transplantation (HCT) Recipients.

The prevalence of Hepatitis C Virus (HCV) infection was reported to range between 10% and up to 30% prior to institution of routine HCV screening in recipients of HCT (hematopoietic cell transplantation). In an Italian prospective study 6% of HCT candidates were positive for HCV RNA. HCV in recipients of HCT carries both short-term and long-term consequences. In the short-term those with HCV after hematopoietic cell transplantation have been associated with risk for sinusoidal obstruction syndrome especially in patients with some level of hepatic dysfunction going in to the transplant. In addition, the type of conditioning chemotherapy (e.g., busulfan) and radiation may increase risk for sinusoidal obstruction syndrome. The rate of hematopoietic recovery was found to be lower in HCV infected recipients, with delayed neutrophil and platelet engraftment.

In the long-term, HCV may flare up once immunosuppression is being tapered off. The issue of reactivation of viral hepatitis (HBV and HCV) after HCT has been well documented. The risk for HCV reactivation in allogenic HCT in one study was reported at 100% by 12 months after HCT, with risk for death related to HCV of 8%. Also, of concern is rapid progression of liver disease in long-term survivors of HCV+ HCT. In such patients, cumulative incidence of cirrhosis has been reported in up to 11% and 24% at 15 and 20 years after HCT respectively.

Hepatitis C infection is associated with significant morbidity and mortality, due to the short-term and long-term complications associated with it. Treatment of hepatitis C virus with direct-acting antiviral (DAA) agents pre-hematopoietic cell transplantation (HCT) in candidates with hepatitis C may lead to reduction of both short-term and long-term complications from it.

Treatment with DAA's pre-HCT in candidates with hepatitis C would potentially prevent complications of hepatitis C infection; prevent reactivation of hepatitis C post-HCT, prevent delay in hematopoietic recovery (especially neutrophils and platelet), possibly reduce risk for sinsusoidal obstruction syndrome, prevent relapse of malignancy that could be related to hepatitis C (non-Hodgkin lymphoma), reduce non-relapse mortality and long-term complications (cirrhosis).

Read the detailed description

This is an open-label observational/ feasibility study to treat candidates for HCT infected with hepatitis C prior to the transplantation to reduce the complications associated with hepatitis C in the post-transplant setting.

The study will be conducted at Kaiser Permanente Los Angeles Medical Center and City of Hope National Medical Center, Duarte, CA.

There is no data available on the outcomes of treating hepatitis C with DAA's pre-HCT in candidates with hepatitis C infection. The ASBMT task force made recommendation to consider treating hepatitis C infection pre-HCT based on potential benefits it may be associated with. A single case report has documented benefit of treating a donor infected with hepatitis C prior to stem cell collection with DAA and ribavirin

Subject Population will include autologous or allogeneic HCT candidates (for hematologic malignancy) who have hepatitis C infection. Subjects will be considered treatment-experienced if they have received prior interferon-based therapy. Treatment-experienced patients with prior use of DAA(s) are excluded from study participation.

This study will treat HCV patients prior to HCT, with the goal of reducing early post HCT complications in the first 100 days post HCT followed by measuring outcomes at 2 years post HCT.

Subjects will receive LDV 90mg/SOF 400mg FDC for 12 weeks.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Safety and Tolerability of LDV/SOF Treatment in Candidates for HCT with hepatitis C infection

    To assess the safety and tolerability/feasibility of the two agent combination, ledipasvir and sofosbuvir (LDV/SOF), through evaluation of toxicities, including type frequency, severity, attribution, time course and duration.

    Measured: 2 year

Secondary outcomes (5)
  1. Rate of HCV Relapse Post HCT

    To estimate the rate of hepatitis C relapse post HCT - until 2 year after HCT

    Measured: 2 Years

  2. Effect of Virologic Suppression on Post HCT Complications

    To evaluate the effect of virologic cure on the short term complications after HCT: hematopoietic recovery (neutrophil and platelet count), liver test abnormality, sinusoidal obstruction syndrome, liver disease decompensation in those with advanced fibrosis

    Measured: 2 Years

  3. Proportion of Patients with Sustained Virologic Response at Time of Transplant

    To estimate the proportion of patients who attained SVR by the time of transplantation (day 0 of HCT), and remain HCV negative at day 30, day 100, day 180, year 1 and year 2 post HCT

    Measured: 2 Years

  4. Cumulative Incidence of HCV Relapse

    To estimate the cumulative incidence of hepatitis C relapse

    Measured: 2 Years

  5. Progression of Liver Fibrosis After Transplant

    Monitoring for progression of liver fibrosis post-HCT compared to baseline (prior to initiation of DAA treatment)

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Ledipasvir 90mg/Sofosubvir 400mg in people with Hematopoietic Stem Cell Transplantation, run by Kaiser Permanente at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 18 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 31 Aug 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety and Tolerability of LDV/SOF Treatment in Candidates for HCT with hepatitis C infection (time frame: 2 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Aug 2018.
