HCV-HIV Co-Infection Clinical Trial
— QUADRIHOfficial title:
Pilot Study to Assess the Efficacy and Tolerance to a QUadruple Therapy With Asunaprevir , Daclatasvir, Ribavirin and Pegylated Interferon Alpha-2a, in HIV-HCV Genotype 1 or 4 Coinfected Patients Previously Null Responders to a Standard Pegylated Interferon -Ribavirin Regimen
Evaluation of efficacy and tolerance to a QUadruple therapy with Asunaprevir , Daclatasvir,
Ribavirin and pegylated Interferon alpha-2a, in HIV-HCV genotype 1 or 4 coinfected patients
previously null responders to a standard Pegylated Interferon -Ribavirin regimen.
The proportion of patients presenting cirrhosis (defined by a METAVIR F4 score on liver
biopsy and/or with hepatic impulse elastometry ≥ 15 kPa) will be limited to 50% of all of
the patients included

Inclusion Criteria: - Adult =18 years with confirmed HIV-1 or 2 infection - Infection with HCV genotype 1 or 4 only, confirmed and with detectable HCV-RNA = 1000 IU/mL at screening. - Null responders to a previous treatment with Peginterferon and Ribavirin, defined by a fall of less than 2 log10 IU/ml HCV-RNA from baseline to week 12. - Stable antiretroviral treatment for > 1 month at screening containing any of the following drugs: Raltegravir, Enfuvirtide, Tenofovir-Emtricitabine, Abacavir-Lamivudine. - CD4 > 200 /mm3 and > 15% at screening - HIV-RNA < 400 copies/mL from = 3 months at screening - Any liver fibrosis stage, - with the assessment of the presence or not of cirrhosis at screening: - previous liver biopsy exhibiting cirrhosis lesions (METAVIR F4), and/or - significant liver biopsy (cumulative length = 15 mm and = 6 portal spaces), within 18 months and after the end of last HCV treatment, and/or - significant and reliable liver stiffness assessment (Fibroscan®) within 6 months (at least 10 measures with IQR less then 25% of the mean value and a success rate of at least 80%) - cirrhosis being defined as a METAVIR score F4 on liver biopsy and/or liver elastometry = 15 kPa - the proportion of patients with cirrhosis (METAVIR F4) is limited to 50% of all patients. - Body weight = 40 kg and =125 kg - Male patients, female patients with child-bearing potential and their heterosexual partners must use adequate contraception from 1 month before initiation of treatment to 7 months following the end of treatment for men and to 4 months following the end of treatment for women. - Informed and signed consent - For participating patients, informed and signed consent for the pharmacokinetic sub-study - Patients affiliated to the National Health Insurance or covered by Universal Medical Coverage - For the first 12 patients included (who will participate to the pharmacological substudy): stable antiretroviral treatment for > 1 month at screening, with Raltegravir+ Emtricitabine+ Tenofovir Exclusion Criteria: - CHILD B and C cirrhosis, past history of decompensated cirrhosis. Patients with CHILD A cirrhosis must demonstrate the absence of significant oesophageal varices (Stages 2-3) on an upper gastrointestinal endoscopy = 12 months - Positive HBs antigenemia with HBV DNA > 1000 IU/ml((if positive AgHBs with HBV DNA = 1000 IU/mL, patient will be included provided it is treated with Ténofovir) - Pregnant women, breast-feeding women - Refusal of adequate contraception - Contra-indication to Ribavirin, including hypersensitivity reaction to Ribavirin - Contra-indication to Peginterferon, including psychiatric contra-indications. Patients with significant psychiatric past history, notably severe depression requiring hospitalization or suicide attempt, cannot be included unless they undergo a psychiatric evaluation and obtain a specific authorization for the use of interferon. - Premature discontinuation (during the first six months) of a previous HCV treatment for toxicity. Patients who have stopped a previous treatment for severe anaemia or neutropenia can enter the study if erythropoietin or granulocyte growth factor had not been used during the previous treatment - Previous HCV therapy including HCV NS3 protease inhibitor - Severe pre-existing cardiac or pulmonary disease - History of organ transplant - Acute CDC stage C opportunistic infection occurring within the previouW6 months - Any active malignant disease including hepatocellular carcinoma for which a specific assessment is required at screening - Alcohol intake that may represent an obstacle for the participation of the subject in the study - Substance abuse that may represent an obstacle for the participation of the subject in the study. Stabilized patients included in a substitution program can participate in the study - Patients with previous observance problem unable to observe the study procedures - Participation in another clinical trial within the previous 30 days - Haemoglobin < 90 g/L - Platelets < 50 000 /mm3 - Neutrophil count < 750 /mm3 - Renal insufficiency defined by an estimated Glomerular Filtration Rate < 50 mL/mn (MDRD equation) - Absence of antiretroviral treatment or antiretroviral treatment different from the authorized combinations - Associated medication likely to interfere with any of the study drugs such as CPY3A4 inducers (rifampin, Millepertuis) |
