Clinical Trial Summary

The purpose of this study is to characterize the effect of renal function on the PK of a 0.25 mg single oral dose of bevenopran in humans and to assess the safety and tolerability of bevenopran in patients with varying degrees of renal impairment and in healthy subjects.

Description:

The current Food and Drug Administration (FDA) draft guidance for renal impairment studies advises performance of a PK study in patients with renal impairment for medications primarily excreted in urine and also for medications primarily metabolized or secreted in bile. The major routes of excretion of bevenopran in animals were identified as hepatobiliary and renal. In addition, preliminary findings show >40% of an oral bevenopran dose is eliminated unchanged in urine over a 48-72 hour period post-dose.

This is a Phase 1, non-randomized, parallel group, open-label study to characterize the effect of renal function on the PK of bevenopran in 1 or more study centers. At screening, eligible subjects will be enrolled and assigned to 1 of 5 parallel study groups of approximately 8 to 12 subjects each based on the classification of the renal function using estimated glomerular filtration rate (eGFR) from the Modification of Diet in Renal Disease (MDRD) Study, as presented in the FDA guidance on renal impairment studies. There are 5 study groups based on eGFRs.

Eligibility

Inclusion Criteria:

1. Healthy (other than renal impairment) male or female subjects 18 to 80 years of age, inclusive;

1. Not of child bearing potential, defined as postmenopausal for at least one year or <60 years old with no menses for >1 year confirmed by follicle stimulating hormone (FSH), or surgically sterile due to bilateral tubal ligation, bilateral oophorectomy, or hysterectomy;

2. Of childbearing potential and utilizes one of the following: abstinence, hormonal contraceptives from at least 3 months prior to Screening, intrauterine device (IUD), double barrier method (acceptable double barrier methods are male condom plus sponge/diaphragm/hormones/IUD, condom plus spermicide is not acceptable), in combination with an additional method of contraception for their male partners. Subjects must be willing to practice these methods for the duration of the trial and for at least 30 days after last study drug administration. For dialysis patients (Group E): If female, must not be of child bearing potential, defined as postmenopausal for at least one year or <60 years old with no menses for >1 year confirmed by follicle stimulating hormone (FSH) or subject medical history, or surgically sterile (ie, bilateral tubal ligation, bilateral oophorectomy, or hysterectomy);

5. Male subjects with female sexual partners, must be using and willing to continue using medically acceptable forms of contraception (abstinence, vasectomy, or male condom for subjects plus an additional method of contraception for their female partners) from Screening and for at least 30 days after the last study drug administration;

6. Non-smoker for at least 1 year prior to Screening, as determined by self-reported history;

7. Able to speak, read, and understand English sufficiently to understand the nature of the study, to provide written informed consent, prior to the initiation of any protocol-specific procedures;

8. Must be willing and able to abide by all study requirements and restrictions;

9. Must be willing to abstain from the following foods from 1 week prior to first study drug administration until the end of the study: grapefruit, pomegranate, pomelo and star fruit juice/products, as well as foods containing poppy seeds, Seville oranges, and/or drinks or food containing quinine (ie, tonic water);

10. Must be willing to refrain from consuming more than 450 mg of caffeine per day (equivalent to approximately 2.5 cups of drip coffee);

11. Must be willing to refrain from strenuous physical activity for 48 hours prior to each study visit and during inpatient stays at the research site;

12. Must be willing to abstain from blood donation during the study and for 30 days after completion of study or early termination.

Exclusion Criteria:

1. For healthy subjects: history or presence of any clinically significant illness (e.g., cardiovascular, pulmonary, hepatic, renal, hematologic, gastrointestinal, endocrine, immunologic, dermatologic, neurologic, oncologic, musculoskeletal, or psychiatric) or any other condition, including clinically significant anemia, which in the opinion of the investigator would jeopardize the safety of the subject or the validity of the study results; For renally impaired patients: as above, except renal insufficiency and other related stable medical conditions within the renally impaired subject population (eg, hypertension, diabetes, which should be stable for at least 3 months preceding the initial dose of study drug in this study) are allowed;

2. Clinically significant abnormalities on physical examination, medical history, 12-lead electrocardiogram (ECG), vital signs, or laboratory values, as judged by the investigator or designee. Subjects with renal impairment should have clinical laboratory values consistent with their disease and approved by the investigator;

3. QTcF > 480 ms for renally impaired patients and > 450 ms for healthy subjects;

4. Surgical or medical condition that may interfere with the absorption, distribution, metabolism, or excretion of the study drug, as judged by the investigator or designee;

5. Evidence of clinically significant hepatic (all subjects) or renal (healthy subjects only) impairment including alanine aminotransferase (ALT) or aspartate aminotransferase (AST) > 1.5 × upper limit of normal (ULN) or bilirubin > 1 × ULN;

6. Hemoglobin <9 g/dL, unless not considered clinically significant in the opinion of the investigator;

8. Patients with renal impairment who are not on a chronic stable drug regimen, defined as starting a new drug or changing dosage within 14 days prior to administration of study drug, except for drugs that manage the hemodialysis;

9. Patients with fluctuating or rapidly deteriorating renal function. Assessment of the stability of the patient's renal function will be determined by the investigator;
