Real-World Data Study to Evaluate the Effectiveness of OCA on Hepatic Outcomes in PBC Patients (HEROES PBC)

December 10, 2024 updated by: Intercept Pharmaceuticals

Replicate Studies Evaluating the Effectiveness of Obeticholic Acid on Hepatic Real-World Outcomes in Patients With Primary Biliary Cholangitis

This is an observational, retrospective cohort study of patients with primary biliary cholangitis (PBC) who failed ursodeoxycholic acid (UDCA) treatment, using a real-world data source, the Komodo Health United States (US) claims database. The study is designed to evaluate the effectiveness of obeticholic acid (OCA). All patients who meet diagnostic criteria for PBC in the database between 01 Jun 2015 and 31 Dec 2021 and who meet all eligibility criteria were considered for this study.

Conditions

Conditions

Intervention / Treatment

Intervention / Treatment

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

All patients who meet diagnostic criteria in each database between 01 Jun 2015 and 31 Dec 2021 and who meet the eligibility criteria were considered for these studies.

Key Inclusion Criteria:

  1. Definite or probable PBC diagnosis
  2. Inadequate response or intolerance to UDCA
  3. Age ≥18 years at the index date
  4. Continuous enrollment and evaluable data for at least 12 months before the index date (inclusive)

Key Exclusion Criteria:

  1. History or presence of other concomitant liver diseases
  2. History of non-skin malignancy or melanoma
  3. History of HIV
  4. Medical conditions that may cause non-hepatic increases in ALP

Design Details

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
OCA-treated
PBC participants with a history of UDCA failure (inadequate response, intolerance, or discontinuation) who initiated Obeticholic acid (OCA) in the study window.
Non-OCA Treated
PBC participants with a history of UDCA failure who were eligible but not treated with OCA (or off-label fibrates) in the study window.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Risk of the First Event of the Composite Events
Time Frame: Up to 67 months
The primary analysis outcome was assessed with hazard ratio (HR) comparing hazard of first event of the composite endpoint among OCA-treated participants and SMR-weighted non-OCA-treated PBC participants indexes. It included all-cause death, liver transplant, hospitalization for hepatic decompensation based on first occurrence of: variceal bleed, ascites (including hepatic hydrothorax and spontaneous bacterial peritonitis) and hepatic encephalopathy. OCA-treated indexes were censored 90 days after OCA discontinuation, or if fibrates were initiated. Control indexes were censored if a participant-initiated OCA therapy, initiated fibrate therapy, reinitiated UDCA for participants who had discontinued UDCA for >6 months, or end of study period (31 Dec 2021), whichever came first. The 2.5th and 97.5th percentile of nonparametric bootstrap samples were used to estimate 95% CI for HR and to perform a test of hypothesis. Risk is presented using the number of composite event and components.
Up to 67 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Risk of Death
Time Frame: Up to 67 months
The primary source for death was the Social Security Death Index (SSDI) along with obituary search, which was compared to Komodo Health claims and LabCorp/Quest laboratory data. The secondary objectives were to estimate the effect of OCA treatment versus non-OCA treatment on each component of the composite endpoint, with the same censoring rule applied as in the primary composite endpoint. Risk is presented using the the number of all-cause death within the risk period (prior to censoring).
Up to 67 months
Risk of Liver Transplantation
Time Frame: Up to 67 months
The primary source for liver transplant was the Organ Transplant Network (OPTN) transplant registry. Risk is presented using the number of liver transplantation.
Up to 67 months
Risk of Hospitalization for Hepatic Decompensation
Time Frame: Up to 67 months
The primary source for hospitalization for hepatic decompensation were Komodo Health claims. Risk is presented using the number of hospitalization for hepatic decompensation.
Up to 67 months

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Time Frame
Time to the first occurrence of all-cause death
Time Frame: Time from index date to first occurrence of all-cause death, assessed up to 67 months.
Time from index date to first occurrence of all-cause death, assessed up to 67 months.
Time to the first occurrence of liver transplant
Time Frame: Time from index date to first occurrence of liver transplant, assessed up to 67 months.
Time from index date to first occurrence of liver transplant, assessed up to 67 months.
Time to first occurrence of hospitalization for hepatic decompensation
Time Frame: Time from index date to first occurrence of hospitalization for hepatic decompensation, assessed up to 67 months.
Time from index date to first occurrence of hospitalization for hepatic decompensation, assessed up to 67 months.
