Clinical Trial to Evaluation the Safety and Efficacy of GR-MD-02 for the Treatment of Liver Fibrosis and Resultant Portal Hypertension in Patients With Nash Cirrhosis

Completed · Phase 2 · Has a placebo group

Conditions studied: Hypertension, Portal

In brief

Study GT 026 is a Phase 2, multicenter, parallel group, North American, randomized, placebo controlled, double blind study. This study will enroll subjects with portal hypertension (HVPG greater than or equal to 6 mm Hg) who also have a liver biopsy with cirrhosis (Ishak stage 5 or 6), presumably due to NASH, excluding subjects with medium and large varices and those with decompensated cirrhosis. Subjects with portal hypertension and cirrhosis will be randomly assigned (1:1:1 ratio) to receive 1 of 3 treatment assignments including placebo, GR MD 02 in a dose of 2 mg/kg lean body mass, or GR MD 02 in a dose of 8 mg/kg lean body mass administered every other week over a 52 week period for a total of 26 intravenous infusions. The primary endpoint analysis is the baseline adjusted change in HVPG at 1 year (53 55 weeks) in subjects treated with placebo as compared to subjects treated with GR MD 02 (2 mg/kg/week or 8 mg/kg/week). An esophagogastroduodenoscopy (EGD) with evaluation for varices, HVPG, and liver biopsy will be performed before the first infusion and after the final 26th dose of the investigational medicinal product (IMP). Additionally, subjects will undergo a FibroScan (if available) prior to the first infusion, at Infusion Visit 13, and 14 to 28 days following final 26th infusion, an methacetin breath test (MBT), will be performed if available at screening, at Infusion Visit 13, and 14 to 28 days after the final infusion, and blood will be collected for assessment of biomarkers. All subjects are to attend 2 postdose visits: the first will occur 14 to 28 days after the final dose administration and a second will occur 14 days following the first postdose visit. Subjects will be offered enrollment into a subsequent separate study, an open label extension study, if there is adequate tolerability and no safety issues or signs of clinical progression that would recommend discontinuation. Subjects who do not enroll in the open label extension study will be contacted via telephone every 6 months for 2 years and annually thereafter for a total of 4 years.

Who can join

Age: 18 and older, up to 75. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Has a HVPG measurement ≥6 mm Hg.
• Has a liver biopsy with cirrhosis (Ishak stage 5 or 6) presumably due to NASH. A liver biopsy diagnosis of cirrhosis presumably due to NASH will include the following 3 categories:
• Cirrhosis with a definitive pathological diagnosis of NASH (presence of fat, ballooning degeneration, and inflammation);
• Cirrhosis wherein the biopsy contains either fat (>5%) or ballooning hepatocytes with no evidence of viral hepatitis or other liver disease; or
• Cirrhosis with no evidence of viral hepatitis or other liver disease in a subject with at least a 5 year history of obesity (BMI ≥30) or at least a 5 year history of diabetes mellitus (as defined by diagnosis by a physician and treatment with at least 1 antidiabetic medication).
• Is ≥18 years of age and ≤75 years of age at the time of screening.
• Absence of hepatocellular carcinoma by valid imaging (liver ultrasound, triple phase computed tomography of liver or magnetic resonance imaging of liver) within 6 months prior to randomization. If there is not such test available, then it should be performed as part of standard of care.
• Is willing and able to provide written informed consent prior to the initiation of any study specific procedures.
• Is not pregnant and must have a negative serum pregnancy test result prior to randomization.
• If a fertile man or woman participating in heterosexual relations, agrees to use effective means of contraception (ie, 2 effective methods of contraception, one of which must be a physical barrier method).
• Effective forms of contraception include condom, hormonal methods (birth control pills, injections or implants), diaphragm, cervical cap, or intrauterine device throughout his/her participation in this study and for 90 days after discontinuation of study treatment. Surgically sterile males and females are not required to use contraception provided they have been considered surgically sterile for at least 6 months. Surgical sterility includes history of vasectomy, hysterectomy, bilateral salpingo oophorectomy, or bilateral tubal ligation. Postmenopausal women who have been amenorrheic for at least 2 years at the time of screening will be considered sterile.
• If a lactating woman, agrees to discontinue nursing before the start of study treatment and refrain from nursing until 90 days after the last dose of study treatment.
• If a man, agrees to refrain from sperm donation throughout the study period and for a period of 90 days following the last dose of IMP. Female subjects may not begin a cycle of ova donation or harvest throughout the study period and for a period of 90 days following the last dose of IMP.
• Prior to randomization, any subject on statins, angiotensin converting enzyme inhibitors, angiotensin II receptor blockers, or β 1 selective adrenergic receptor inhibitors should have been on a stable dose for at least 2 months and all attempts should be made to continue the subject on the same dose of the medication for the duration of study participation.

You may not qualify if…

• Has a history of hepatic decompensation including any episode of variceal bleeding, ascites not controlled by medication, or overt hepatic encephalopathy (defined by the clinical judgment of the principal investigator but shall include the presence of lethargy, disorientation, inappropriate behavior, and the presence of asterixis).
• Has a presence of medium or large varices or varices with red signs regardless of size based on endoscopy.
• Small varices are defined by veins that occupy <25% of the distal one third of the esophageal lumen when insufflated. Veins that completely flatten upon insufflation of the esophagus are not conserved varices. Any varices larger than that are medium (up to 50%) or large (>50%).
• Red signs include red wale markings (dilated venules oriented longitudinally on the variceal surface), cherry red spots (small, red, spotty dilated venules usually approximately 2 mm in diameter on the variceal surface) or hematocystic spots (large, round, crimson red projection >3 mm that look like a blood blister on the variceal surface).
• Has had a prior transjugular porto systemic shunt procedure.
• Has evidence of other forms of chronic liver disease including viral hepatitis B or C, primary biliary cirrhosis, primary sclerosing cholangitis, Wilson's disease, alpha 1 antitrypsin deficiency, alcoholic hepatitis, hemochromatosis, liver cancer, history of biliary diversion, or autoimmune hepatitis.
• Has any of the following laboratory values:
• Serum alanine aminotransferase levels >10 × the upper limits of normal
• Serum aspartate aminotransferase levels >10 × the upper limits of normal
• Platelet count <60 000/mm3
• . Serum albumin ≤2.8 g/dL
• International normalized ratio (INR) ≥1.7
• Direct bilirubin ≥2.0 mg/dL
• Alpha fetoprotein >200 ng/mL
• Has a Model End-Stage Liver Disease (MELD) score ≥15 or Child Turcotte Pugh Class B or C.
• Has an estimated creatinine clearance of <50 mL/minute. Glomerular filtration rate will be estimated using the Cockcroft-Gault equation (Cockcroft 1976):
• Males: CrCl (mL/min) = ([140 - age] × weight) / (SCr × 72)
• Females: CrCl (mL/min) = ([140 - age]) × weight) / (SCr × 72)] × 0.85
• Where CrCl is creatinine clearance, age is in years, weight is in kg, and SCr is serum creatinine in mg/dL
• Is unwilling or unable to safely undergo HVPG or liver biopsy.
• Has known positivity for human immunodeficiency virus (HIV) infection or a positive HIV test result at screening.
• Has had major surgery within 8 weeks of randomization, significant traumatic injury within 6 months, or anticipation of need for major surgical procedure during the course of the study.
• Has a history of a solid organ transplant requiring current immunosuppression therapy.
• Has used nonselective β adrenergic inhibitors within 6 weeks prior to randomization.
• Has planned or anticipated variceal ligation therapy during the study.
