Étude d'Elafibranor chez des patients atteints de cholangite biliaire primitive (CBP) (ELATIVE)

20 octobre 2026 mis à jour par: Ipsen

Une étude en double aveugle, randomisée, contrôlée par placebo et une extension à long terme en ouvert pour évaluer l'efficacité et l'innocuité d'Elafibranor 80 mg chez les patients atteints de cholangite biliaire primitive avec une réponse inadéquate ou une intolérance à l'acide ursodésoxycholique

The participants of this study will have confirmed Primary Biliary Cholangitis (PBC) with inadequate response or intolerance to ursodeoxycholic acid (which is a medication used in the management and treatment of cholestatic liver disease).

PBC is a slowly progressive disease characterized by damage of the bile ducts in the liver, leading to a buildup of bile acids which causes further damage. The liver damage in PBC may lead to scarring (cirrhosis). PBC may also be associated with multiple symptoms. Many patients with PBC may require liver transplant or may die if the disease progresses and a liver transplant is not done.

The main aim of this study is to determine if elafibranor (the study drug) is better than placebo (a dummy treatment) at decreasing the levels of a specific blood test (alkaline phosphatase) that provides information about participant's disease. This study will also evaluate the safety of long-term treatment with elafibranor, as well as the impact on symptoms such as itchy skin (pruritus) and tiredness (fatigue).

This study has two main parts:

Part 1 will compare a daily dose of elafibranor to a daily dose of placebo and will last between a minimum of one year and a maximum of two years.

Part 2, all participants will receive elafibranor for a period of up to 5 years or until the total treatment duration (part 1 and part 2) reaches 6 years, whichever occurs first.

Description de la mesure
Délai
Percentage of Participants With Response to Treatment Based on Cholestasis Response at Week 52
Délai: At Week 52

Cholestasis response was defined as alkaline phosphatase (ALP) < 1.67 x upper limit of normal (ULN) and total bilirubin (TB) <= ULN and ALP decrease from baseline >= 15% at Week 52 and based on the composite strategy imputing non-response for participants who experienced intercurrent events (ICEs) (study treatment discontinuation or use of rescue therapy for PBC) prior to Week 52.

Délai
Key Secondary Endpoint: Percentage of Participants With Response to Treatment Based on ALP Normalization at Week 52
Délai: At Week 52

Response to treatment based on normalization of ALP at Week 52 was defined as percentage of participants with ALP =<1.0× ULN and based on the composite strategy imputing non-response for participants who experienced ICEs (study treatment discontinuation or use of rescue therapy for PBC) prior to Week 52.

At Week 52
Key Secondary Endpoint: Change From Baseline in Pruritus Based on PBC Worst Itch Numeric Rating Scale (NRS) Score in Participants With Baseline PBC Worst Itch NRS Score ≥4 to Week 52
Délai: Baseline (up to 14 days pre-dose) and Week 52

The PBC Worst Itch NRS is a simple, self-administered patient reported outcome (PRO) questionnaire that measures itch intensity. Participants rate intensity of their worst Itch on an 11-point scale ranging from 0 (no itch) to 10 (worst itch imaginable). Total score ranged from 0 (no itch) to 10 (worst itch imaginable). Higher scores indicated worse outcomes. Baseline was defined as the average of the daily PBC Worst itch scores on available data within 14 days prior the day of randomization. Post-baseline data was defined as the average of the daily PBC Worst itch scores on available data in 4-week period intervals (available data every 28 days after the day of first study drug intake).

Baseline (up to 14 days pre-dose) and Week 52
Key Secondary Endpoint: Change From Baseline in Pruritus Based on PBC Worst Itch NRS Score in Participants With Baseline PBC Worst Itch NRS Score ≥4 to Week 24

PBC 5-, 10- and 15-year Risk Scores Based on United Kingdom (UK)-PBC Score at Week 52
Délai: At Week 52

The UK-PBC risk score was defined by the mean percentage risk that a PBC participant treated with UDCA would develop liver failure requiring liver transplantation in 5, 10, and 15 years from diagnosis. It is calculated from the following equation at week 52 as follows: UK-PBC score = 0.0287854*(alpEPxULN-1.722136304) - 0.0422873*([{altastEP x ULN/10}^-1] - 8.675729006) + 1.4199 * (LN(bilEPxULN /10)+2.709607778) - 1.960303*(alb x LLN -1.17673001)-0.4161954*(plt x LLN -1.873564875). The survival S(t) for any given participants was then calculated by S(t) = S0(t) exp(UK-PBC score). Here, alpEP x ULN=ALP /Upper Level Normal ALP at the timepoint, altastEPxULN=(ALT, AST or TA) /upper level normal of the value at the timepoint, bilEP x ULN=bilirubin /upper level normal bilirubin at the timepoint, alb x LLN=alb /alb lower level normal at baseline and plt x LLN=plt/plt lower level normal at baseline. Lower UK-PBC score predicts lower risk and better prognosis.

At Week 52
Global PBC Study Group (GLOBE) Score at Week 52
Délai: At Week 52

The GLOBE score was a validated risk assessment tool providing an estimate of transplant-free survival for participants with PBC. It was developed by the Global PBC Study Group using Cox regression model on over 4,000 participants with PBC. It is calculated from the following equation at week 52 as follows: GLOBE score = 0.044378 * age at start of ursodeoxycholic acid (UDCA) therapy + 0.93982 * LN (TB x ULN) + 0.335648 * LN (ALP x ULN) - 2.266708 * ALB x LLN - 0.002581 * platelet count per 10^9/L) + 1.216865; where TB x ULN = bilirubin/ULN at the timepoint, ALP x ULN = ALP/ULN at the timepoint, ALB x LLN = ALB/LLN at the timepoint, platelet count per 10^9/L = platelet count per 10^9/L at the timepoint. The Lower GLOBE PBC score predicts lower risk and better prognosis.

Change From Baseline in T-Scores for Bone Mineral Density Assessed by Dual-energy X-ray Absorptiometry (DEXA) Scanning at Week 52
Délai: Baseline (Day 1) and at Week 52

DEXA scanning (hip and lumbar) was performed in participants to assess bone mineral density (femoral neck, lumbar and total hip). T-scores were calculated based on actual measured bone density value. The T-score compared a participant's bone density against that of a healthy 30-year-old adult. T-scores were used to determine primary osteoporosis, which exists on its own without any other cause and were divided into 3 categories: low risk, medium risk, and high risk (osteoporosis). T-scores measure the number of minerals in a participant's bone. A participant's level of bone loss was compared to that of a typical, healthy 30-year-old adult. A score ≥-1.0 indicates low risk, medium risk is a score between-2.5 and -1.0, and a high risk/osteoporosis is a score ≤-2.5. A positive change in T-score indicates an improvement in bone mineral density. Baseline was defined as the last non-missing central value on or before the first dose of the randomized study medication.

A TEAE was defined as any AE with onset during TEAE assessment period, or any event started prior to first dose of treatment and worsened or became serious during the TEAE assessment period. An SAE was any AE that resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital abnormality/birth defect. An AESI was an AE that might not be serious but was of special importance to a particular treatment or class.
