Trial summary

In the medical literature there case reports that Harvoni improves symptoms in patients with PCT. However, this has never been systematically tested. Therefore, the purpose of this study is to assess whether Harvoni alone is an effective therapy of active PCT in patients with Chronic Hepatitis C. Read more about this study

Who may be able to join

  • Willing and able to give informed consent

  • Ongoing active alcohol abuse, defined as a history of drinking more than 25 drinks of alcohol per week during most weeks in the prior 4 months (History of prior, but not current alcohol abuse will NOT be grounds for exclusion because we seek to treat subjects with PCT and CHC of the type typically seen in clinical practice)

Show all 21Show fewer

  • Known or suspected hepatocellular carcinoma
  • On liver transplant list, or current MELD >12
  • History of liver transplant

About this study

Official title: Newer Direct-Acting Anti-Viral Agents as Sole Therapy of Porphyria Cutanea Tarda in Subjects With Chronic Hepatitis C

In the medical literature there case reports that Harvoni improves symptoms in patients with PCT. However, this has never been systematically tested. Therefore, the purpose of this study is to assess whether Harvoni alone is an effective therapy of active PCT in patients with Chronic Hepatitis C.

Read the detailed description

This is a clinical trial, which means its purpose is to study an intervention or treatment. In this study all patients with PCT will be given a standard dose of Harvoni and monitored for two years. Currently there are two standard therapies for PCT, phlebotomies (removing certain amounts of blood at specific intervals), or low dose hydroxychloroquine (an oral pill). These treatments are used for patients with PCT whether or not they also have HCV. For patients with HCV however, we do not know whether treating the HCV first will also resolve the PCT symptoms. There will be an initial visit to determine whether participants are eligible to be in the study. If a participant is found to be eligible, he/she will be asked come to the study site once every month over the course of one year, and then once every 3 months for an additional year. There will be approximately 17 visits over the course of the whole study. At these visits the study doctors will check in with the participant and some blood and urine samples will be taken. Participants will not be charged for any of the lab tests that are being done as a part of this study alone. All participants in this study will receive the Harvoni pills at no cost to them.

What is being measured

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

  1. Number of Participants With Resolution of Active PCT by 7 Months After Start of Therapy

    Resolution of active PCT, defined as normalization of plasma porphyrins (less than 0.9 mcg/dL) by 7 months after start of therapy

    Measured: 7 months

Secondary outcomes (3)
  1. Time to Resolution of Active PCT

    Time to resolution of active PCT, defined as cessation of any new blisters or bullae and normalization of plasma porphyrins

    Measured: through study completion, an average of 1 year

  2. Number of Participants With Complete Biochemical Remission of PCT

    Defined as a decrease of the sum of urinary uro- and hepta-carboxyl porphyrins to less than 100 mcg/g creatinine and a normal urine porphyrin HPLC pattern defined as the total of highly carboxylated porphyrins (uro- and heptacarboxyl-porphyrins) being less than that of coproporphyrins, and the absence of a plasma fluorescence peak by fluorescence scanning

    Measured: 12 Months

  3. Number of Participants With Cure of CHC

    Defined as no detectable HCV RNA at end of treatment and persisting for at least 12 weeks after end of treatment.

    Measured: Up to 15 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Harvoni in people with Porphyria Cutanea Tarda and Hepatitis C, run by Wake Forest University Health Sciences at 3 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 6 inclusion and 21 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: finished, as of the sponsor's last update on 3 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 3 Jul 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Participants With Resolution of Active PCT by 7 Months After Start of Therapy (time frame: 7 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03118674, which also lists 1 linked publication.

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 3 Jul 2023.
