Randomized Double-Blind Placebo-Controlled Phase 3 Study to Evaluate the Efficacy and Safety of Maralixibat in the Treatment of Participants with Cholestatic Pruritus

The purpose of this study is to determine whether the investigational treatment (maralixibat) is safe and effective in pediatric and adult participants who have cholestatic liver disease with pruritus that has been refractory to other therapies, and who have no other treatment options.

Maralixibat in Patients With Cystic Fibrosis and Constipation, A Within-Subjects Pilot Study

Chronic constipation is a feature of children with cystic fibrosis (CF). This is postulated to be a result of inhibition of secretory activity of the gastrointestinal luminal cells due to ineffective chloride channel function. Typical laxatives that work as osmotic agents fail to produce adequate relief in this population.
Maralixibat is a non-systemic bile acid transport inhibitor (IBATi) that acts by interrupting bile acid reabsorption in the ileum thus interrupting the normal enterohepatic circulation. This interruption results in a larger volume of bile acids reaching the colon and being excreted in stool. Bile acids are known to decrease bowel transit time, increase mucosal permeability and secretions, as well as alter gut microbiota resulting in diarrhea.
The overarching hypothesis of the study is that Maralixibat will improve stool consistency in children (Age <18 years) with cystic fibrosis and constipation (Bristol Stool Scale <4). Specifically, we aim to test the hypothesis that IBATi improves the consistency of stool to Bristol scale >4 in children with CF and constipation.
We will recruit a total of 20 patients with CF and constipation (defined as Bristol Stool Scale <4 for 1 week prior to enrollment while on a stable laxative regimen for at least 4 weeks.) Design is a 'Within-Subjects' study by which each enrolled patient will take Maralixibat for 2 weeks total in addition to their stable laxative regimen during the study. Stool consistency & ease of defecation will be recorded before and during the study period by families of enrolled patients via materials provided by the investigators. Stool consistency and ease of defecation will be compared before and after initiation of Maralixibat.
The primary endpoint: Improvement in stool consistency to Bristol scale >4 in children with CF and constipation. The secondary endpoint: Improvement in ease of defecation in children with CF and constipation. This will be measured via survey using a standardized scale (Bristol Stool Scale) and questionnaires developed by the research team. Analysis will involve comparison of pre-intervention to post-intervention stool consistency & survey

Structure–Activity Relationships and Target Selectivity of Phenylsulfonylamino-Benzanilide Inhibitors Based on S1647 at the SLC10 Carriers ASBT, NTCP, and SOAT

Article

Author: Neubauer, Anita ; Fühler, Bärbel ; Lotz, Philipp ; Daude, Michael ; Geyer, Joachim ; Neelen, Christopher ; Diederich, Wibke E. ; Wannowius, Marie

The intestinal bile acid carrier ASBT (SLC10A2), the hepatic bile acid carrier NTCP (SLC10A1), and the steroid sulfate carrier SOAT (SLC10A6), all members of the solute carrier family SLC10, are established drug targets. The ASBT inhibitors odevixibat, maralixibat, and elobixibat are used to treat intrahepatic cholestasis, cholestatic pruritus, and obstipation. The peptide drug bulevirtide blocks binding of the hepatitis B and D viruses to NTCP and thereby inhibits the virus's entry into hepatocytes. Experimental SOAT inhibitors have antiproliferative effects on hormone-dependent breast cancer cells. The phenylsulfonylamino-benzanilide S1647 is an inhibitor of ASBT and SOAT. The present study aimed to comparatively analyze a set of newly synthesized and commercially available S1647 derivatives for their transport inhibition against ASBT, NTCP, and SOAT. Structure-activity relationships were systematically analyzed regarding potency and target specificity to elucidate whether this compound class is worth being further developed in preclinical studies for pharmacological ASBT, NTCP, and/or SOAT inhibition.

Stereoselective Synthesis of Maralixibat via VO(acac)₂/Schiff Base-Catalyzed Asymmetric Oxidation of Its Sulfide Intermediate

Article

Author: Peng, Ziyu ; Mpofo, Mercy ; Ye, Long ; Jie, Zheng

The stereoselective synthesis of maralixibat was achieved by harnessing the chiral transferring effect of the stereogenic R-sulfoxide functionality, which was obtained via the VO(acac)₂/Schiff base-catalyzed asymmetric oxidation of a phenylthiophenol prochiral intermediate. The R-sulfoxide intermediate underwent a ring closure reaction to form the seven-membered ring core structure with the desired stereochemistry, ultimately ensuring the drug's exceptional isomeric purity and synthetic efficiency.

[Progress in the treatment of progressive familial intrahepatic cholestasis].

Review

Author: Liu, T ; Wang, J S

Progressive familial intrahepatic cholestasis (PFIC) is an important cause of liver-related death or transplantation in children. The PFIC spectrum is expanding, twelve types of PFIC are currently included in the Online Mendelian Inheritance in Man (OMIM) database. With the increase of PFIC types and the inconsistence of certain types in numbering, the current numbering classification of PFIC is confusing, so the experts in the field recommend using the corresponding mutant gene/ protein defect to name different type of PFIC except for PFIC type 1-3. The clarification of the genotype-phenotype relationship and/or the establishment of phenotypic predictors significantly improved the management of patients with PFIC. Odevixibat and maralixibat, inhibitors of the apical sodium ion-dependent bile acid transporter on the intestinal epithelial cells, were approved in European Union and the United States for the treatment of PFIC pruritus in 2021, expanding the treatment options for PFIC. Additionally, personalized treatments for specific mutations and novel gene therapy is promising.

Volixibat Granted Breakthrough Therapy Designation for Cholestatic Pruritus in Primary Biliary Cholangitis

- Designation based on positive interim analysis of Phase 2b VANTAGE study FOSTER CITY, Calif.--(BUSINESS WIRE)-- Mirum Pharmaceuticals, Inc. (Nasdaq: MIRM) today announced that the U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy Designation to volixibat as a potential treatment for cholestatic pruritus in patients with primary biliary cholangitis (PBC). The regulatory designation is based on the positive interim analysis of the Phase 2b VANTAGE study which showed statistically significant improvement versus placebo in pruritus for patients treated with volixibat. The confirmatory portion of the study is ongoing with completion of enrollment expected in 2026. “Breakthrough Therapy Designation for volixibat in PBC underscores the importance and urgency for a treatment to address one of the most burdensome impacts of this rare liver disease,” said Joanne Quan, MD, chief medical officer at Mirum. “We look forward to advancing our VANTAGE study with the goal of making volixibat available to patients living with PBC-related itch as quickly as possible.” The FDA’s Breakthrough Therapy Designation aims to expedite the development and review of drugs that are intended to treat serious or life-threatening diseases. To qualify for this designation, preliminary clinical evidence must indicate that the drug may demonstrate substantial improvement over existing therapy on at least one clinically significant endpoint. About Volixibat Volixibat is an oral, minimally absorbed agent designed to selectively inhibit the ileal bile acid transporter (IBAT). Volixibat may offer a novel approach in the treatment of adult cholestatic diseases by blocking the recycling of bile acids, through inhibition of IBAT, thereby reducing bile acids systemically and in the liver. Volixibat is currently being evaluated in Phase 2b studies for primary sclerosing cholangitis (VISTAS study), and primary biliary cholangitis (VANTAGE study). In June, Mirum announced positive interim results from the Phase 2b VANTAGE study showing statistically significant improvement in pruritus as well as meaningful reductions in serum bile acids and improvements in fatigue for patients treated with volixibat. No new safety signals were observed, and the most common adverse event was diarrhea with all cases mild to moderate. About Mirum Pharmaceuticals, Inc.
