Plain English summary of protocol

Background and study aims
Nonalcoholic steatohepatitis (NASH) is a leading cause of liver failure and cirrhosis in the world. There is no approved treatment for this disease.
Curcumin is a natural spice component that showed benefits in experimental models of NASH and improved surrogate markers of liver disease in humans, but its actual efficacy on liver histology, which is the main determinant factor of liver disease progression to cirrhosis, is unknown.

Who can participate?
Any adult patient with a biopsy-proven diagnosis of NASH, who is not involved in other experimental trials.

What does the study involve?
This study involves taking curcumin pills for 18 months and undertaking periodical office visits every 3 months. At the end of the treatment, liver biopsy will be repeated.

What are the possible benefits and risks of participating?
The possible benefits are the reversal of liver disease and the stop of progression to cirrhosis: the risks include allergic reactions to curcumin or to any component of the curcumin formulation and the risks associated with liver biopsy(pain, bleeding), which are very rare

Where is the study run from?
HUMANITAS Gradenigo hospital, Turin (Italy)

When is the study starting and how long is it expected to run for?
May 2018 to December 2022

Who is funding the study?
Indena S.p.A. (Italy), the manufacturer of this curcumin formulation, is funding the study

Scientific titleSafety and efficacy of phytosomial curcumin in non-alcoholic seatohepatitis (NASH): a double-blind, randomized, placebo-controlled trial
Study objectivesIn patients with biopsy-proven nonalcoholic steatohepatitis (NASH), phytosomal curcumin for 18 months is safe, induces NASH resolution, and ameliorates histological features and NASH-associated cardiometabolic risk factors as compared with placebo.
Ethics approval(s)Approved 25/05/2018, A.O.U. San Luigi Gonzaga di Orbassano Ethics Committee (Azienda Ospedaliera Universitaria San Luigi Gonzaga, Regione Gonzole 10, 100043 Orbassano, Torino, Italy; +39 11-9026566
sperimentazioni@sanluigi.piemonte.it), ref: 0008942
Health condition(s) or problem(s) studiedNonalcoholic steatohepatitis
InterventionPharmacological intervention (phytosomal curcumin) vs. placebo

Upon acceptance, patients will be randomly (computer-generated sequence) and double-blindly assigned to phytosomial curcumin 1 g twice daily or identical appearing placebo by mouth for 18 months. Both patient arms will be instructed to follow an intensive lifestyle program by an experienced dietician.
The following design will be applied:
-Randomization: computer-generated randomization table
-Double-blinding: pill containers coded with a similar number and with identical appearance. Pills will have identical appearance.
-Allocation concealment: the randomization table will be kept by the pharmacy where the pills have to be taken by the patients, so that only the pharmacist will know which intervention the patient will receive
-Stratification for: age decade, BMI range (normal weight, overweight, obese), sex, diabetes status (present/absent)
-Compliance assessment: pill count returned to the pharmacist

Periodical study visits: every 3 months all patients will undergo periodical check-up visits with individual interview, anthropometry, upper abdominal ultrasound and routine biochemistry.

End-of-treatment assessment: after 18 months of treatment, patients will repeat baseline assessment, including liver biopsy, oral glucose tolerance test, oral fat tolerance test, anthropometry upper abdomen ultrasound and biochemistry

Follow-up, end-of-study visit: 3 months after the end of treatment assessment, patients will undergo individual interview, anthropometry, upper abdominal ultrasound and routine biochemistry.

Primary outcome measureHistological NASH resolution measured using the NASH Clinical Research Network criteria) after 72 weeks. Liver biopsies will be read and scored by a single pathologist (RP), who will be blinded to patient clinical characteristics and treatment allocation.
Secondary outcome measuresCurrent secondary outcome measures as of 17/06/2022:
1. A ≥1 stage improvement in NAFLD fibrosis stage and no worsening of NASH (with worsening defined as an increase of ≥1 point in either the lobular inflammation score or the hepatocyte ballooning score according to the NASH Clinical Research Network criteria) after 72 weeks
2. A ≥2-point improvement in NAFLD activity score (NAS), with at least 1 point improvement in either ballooning or lobular inflammation score according to the NASH Clinical Research Network criteria) after 72 weeks
3. Individual components of the NAFLD activity score (steatosis, hepatocyte ballooning, lobular inflammation) and the Kleiner fibrosis stage. Fibrosis stages 1a, 1b, and 1c were considered stage 1 for the purposes of analysis according to the NASH Clinical Research Network criteria) after 72 weeks
4. Changes from baseline to 48 weeks in serum liver enzyme concentrations, non-invasive biomarkers /scores of liver disease severity(including, but not limited to, cytokeratin 18 fragments, NAFLD fibrosis score, FIB-4), fasting lipid concentrations, glycaemic control (fasting plasma glucose, HbA1c), whole-body insulin resistance (fasting homoeostasis model of assessment of insulin resistance [HOMA-IR] and adipose tissue insulin resistance [ADIPO-IR]), anthropometric measures (body weight, BMI, waist circumference), physical activity and daily dietary consumption.
5. Safety endpoints included adverse events after the start of treatment, biochemical assessments, and clinical assessments. Selected events (including deaths, cardiovascular events, and acute pancreatitis) were adjudicated by an independent, external event-adjudication committee, whose members were unaware of the treatment assignments.
6. Change in estimated glomerular fuiltration rate (eGFR) at 18 months
7. Change in albuminuria measured using the albumin/creatinine ratio (ACR) at 18 months


Previous secondary outcome measures:
1. A ≥1 stage improvement in NAFLD fibrosis stage and no worsening of NASH (with worsening defined as an increase of ≥1 point in either the lobular inflammation score or the hepatocyte ballooning score according to the NASH Clinical Research Network criteria) after 72 weeks
2. A ≥2-point improvement in NAFLD activity score(NAS), with at least 1 point improvement in either ballooning or lobular inflammation score according to the NASH Clinical Research Network criteria) after 72 weeks
