Safety and Efficacy of Roflumilast and Pioglitazone in Treating Adults With Nonalcoholic SteatoHepatitis

A Randomized, Double-Blind, Controlled, Multi-Center Phase 2 Study to Evaluate the Effect of Roflumilast Plus Pioglitazone on Liver Enzymes and Liver Fat Content in Subjects With Nonalcoholic SteatoHepatitis

The purpose of this study is to evaluate the effect of roflumilast and pioglitazone therapy on serum transaminase (ALT) levels in adults with Nonalcoholic SteatoHepatitis.

Study Overview

• Status: Terminated
• Conditions: Nonalcoholic Steatohapatitis
• Intervention / Treatment: Drug: Roflumilast; Drug: Pioglitazone; Drug: Placebo; Drug: Placebo

Detailed Description

This proof of concept study will evaluate the effect of roflumilast and pioglitazone on transaminase levels and liver fat content.

Takeda has chosen not to continue this Study, however, randomized subjects were allowed to complete the study per protocol.

The decision to terminate the study is not related to any safety concerns with either of the study medications.

Exclusion Criteria:

1. The subject has a history of chronic liver disease other than NASH eg, chronic or acute hepatitis, Wilson's disease, alcoholic liver diseases or any other non-NASH active liver disease.
2. Subjects with liver cirrhosis (of any cause) or laboratory or clinical signs of functional liver failure
3. Clinically relevant abnormal laboratory values suggesting an undiagnosed disease other than NASH requiring further clinical evaluation (as assessed by the Investigator).
4. The subject has active cancer or a history of a malignant disease (except basal cell carcinoma) within 5 years prior to Screening or any history of bladder cancer.
5. Subject with a history of weight loss or weight gain of >10 pounds within 6 months prior to Screening.
6. Subject with a history of bariatric surgery within 5 years prior to Screening.
7. The subject has received any investigational compound within 30 days prior to Screening or is currently participating in another clinical study.
8. The subject has a history of hypersensitivity or allergies to roflumilast or pioglitazone including any associated excipients.
9. The subject is required to take excluded medications.
10. The subject has taken oral or injectable glucocorticoids for longer than 7 days within 3 months prior to Screening.
11. The subject has poorly controlled Type 1 or Type 2 diabetes mellitus with an HbA1c ≥8.5 at Screening or per Investigator judgment.
12. The subject has hepatitis A, B or C.
13. The subject has severe immunological diseases (eg, known HIV infection, multiple sclerosis, lupus erythematosus, progressive multifocal leukoencephalopathy) assessed at Screening.
14. The subject had a history of diabetic gastroparesis or history of gastric bypass surgery.
15. The subject had a history of coronary angioplasty, coronary stent placement, coronary bypass surgery, or myocardial infarction within 6 months prior to Screening.
16. The subject had New York Heart Association heart failure of Class (II-IV) regardless of therapy.
17. The subject had a diastolic blood pressure greater than 100 mm Hg or a systolic blood pressure of greater than 160 mm Hg (The mean of the 3 serial BP measurements will be used to determine subject eligibility).
18. The subject has presence or history of psychotic disorder that may be associated with suicidal thinking, ideation or behavior. These disorders include, but are not limited to, depression, psychosis, psychotic disorder, and schizophrenia. Subjects will be monitored by Columbia-Suicide Severity Rating Scales throughout the duration of the study.
19. The subject has a history of drug abuse (defined as illicit drug use) or a history of alcohol abuse (defined as regular or daily consumption of more than 2 alcoholic drinks per day for women or 3 alcoholic drinks per day for men. One drink is equivalent to a 12-ounce beer, a 4-ounce glass of wine, or a 1-ounce shot of hard liquor.) within 1 year prior to the Screening visit.
20. The subject has a hemoglobin <120 g/L for men and <100 g/L for women.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Amount of Serum Alanine Transaminase (ALT) at Baseline		Baseline
Percent Change From Baseline in Serum ALT at Month 4	The percent change between the serum ALT value collected at Month 4 or final visit relative to baseline.	Month 4

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Amount of Serum Aspartate Transaminase (AST) at Baseline		Baseline
Percent Change From Baseline in Serum AST at Month 4	The percent change between the serum AST value collected at Month 4 or final visit relative to baseline.	Month 4
Liver Fat Content at Baseline	Liver fat content was quantitatively measured by evaluating the percentage of proton density fat fraction (PDFF) from an abdominal magnetic resonance imaging (MRI). On the basis of Couinaud classification (a classification used to describe functional liver anatomy), the liver was divided into 8 segments: caudate, left superolateral, left inferolateral, left superomedial (4a), left inferomedial (4b), right anteroinferior, right posteroinferior, right posterosuperior and right anterosuperior.	Baseline
Change From Baseline in Liver Fat Content at Month 4	Liver fat content was quantitatively measured by evaluating the percentage of PDFF from an abdominal MRI.
