Harvoni Treatment Porphyria Cutanea Tarda
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.
- Porphyria Cutanea Tarda
- Hepatitis C
- Eligible Ages
- Over 18 Years
- Eligible Genders
- Accepts Healthy Volunteers
- Willing and able to give informed consent 2. ≥18 years of age 3. Symptoms and signs consistent with PCT and well documented biochemical diagnosis (urinary total porphyrin excretion > 500 mcg/g Creatinine with HPLC pattern typical of PCT-predominance of 8- and 7-carboxyl porphyrins) 4. Clinical diagnosis of PCT established by a study PI 5. Chronic hepatitis C: HCV RNA positive and quantifiable in serum detected within 90 days of enrollment, and documented HCV genotypes 1,4, 5, or 6 for which Harvoni is an approved therapy. 6. Women of child-bearing potential must be willing to avoid pregnancy and use an accepted and effective contraceptive method during treatment.
- Women who are pregnant or who are breast-feeding 2. Patients who have already started treatment of PCT with phlebotomy or low dose hydroxychloroquine or chloroquine, or who have been in such treatment in the past 30 days 3. Patients who have already started another treatment regimen for CHC, or who have taken such treatment in the past 30 days 4. HIV infection with CD4 counts at baseline less than 350/µL or with evidence of any active AIDS-defining illnesses 5. 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) 6. Any ongoing active IV drug use 7. Patients who are taking amiodarone or who have taken amiodarone within 60 days prior to enrollment 8. Patients who are taking, or within the prior 28 days have taken, rifampicin or St John's wort (Hypericum perforatum), both of which are P-gp inducers, which may significantly reduce the drug levels and therapeutic effects of Harvoni 9. Uncontrolled diabetes (Hgb A1c >9.5% within 60 days prior to enrollment) 10. Chronic hepatitis B 11. Autoimmune hepatic liver injury-autoimmune hepatitis, primary biliary cholangitis/sclerosing cholangitis or overlap syndrome 12. Alcoholic hepatitis 13. Other metabolic disorders of the liver, e.g. Alpha 1 antitrypsin deficiency with ZZ Pi type, Wilson's disease 14. Prior known or suspected drug-induced liver injury within 6 months of enrollment 15. Known or suspected hepatocellular carcinoma 16. On liver transplant list, or current MELD >12 17. History of liver transplant 18. Estimated GFR (Creatinine clearance) <30 mL/min (per Sofosbuvir being cleared by the kidney) 19. Serum ALT or AST >10x normal 20. Serum bilirubin >2 mg/dL (excluding patients with known or suspected Gilbert's syndrome) 21. Any other comorbid condition, which, in the opinion of the investigator, precludes participation

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.
