Pharmacokinetic Study of Intranasal RX0041-002 in Hepatic-Impaired Individuals and Subjects With Normal Hepatic Function

Completed · Phase 1

Conditions studied: Analgesic Allergy

In brief

The primary objective of this study is to evaluate the potential effect of hepatic impairment on the systemic pharmacokinetics of RX0041-002 following single dose intranasal administration. The secondary objective is to evaluate the safety and tolerability of intranasal RX0041-002 in subjects with normal hepatic function and hepatic impairment.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Male or female.
• Greater than or equal to 18 years of age and able to understand and comply with protocol requirements, provide written informed consent and HIPAA authorization; ± 10 years for individual age-matched controls.
• Females (if of child-bearing potential and sexually active) and males (if sexually active with a partner of child-bearing potential) who agree to use a medically acceptable and effective birth control method from the first dose and for 8 days following administration of study drug. Medically acceptable methods of contraception that may be used by the participant and/or his/her partner include abstinence, birth control pills or patches, diaphragm, intrauterine device (IUD), condom, surgical sterilization, and progestin implant or injection. Prohibited methods include: the rhythm method or withdrawal.
• BMI ≥ 18 ≤ 32 ; ± 20% for BMI-matched controls
• Clinical laboratory values within the laboratory's stated normal range; if not within this range, they must be without any clinical significance.
• In general, good health aside from hepatic disease (for the hepatically impaired group only) and associated conditions as ascertained by physical examination (PE) including measurement of supine and standing vital signs, medical history, clinical laboratory evaluation, and 12-lead electrocardiogram (ECG).
• Hepatic Subjects
• Hepatic-impaired subjects will be Class B or C according to Child-Pugh classification. The hepatic impairment will have been identified by a typical medical history, physical examination, coagulation tests and abnormal liver function tests (including bilirubin and albumin) at screening.
• Healthy Volunteers
• Volunteers will be healthy and age, BMI and gender-matched controls for the hepatic subjects.

You may not qualify if…

• A subject will be excluded from the study if he or she meets the following criteria:
• Less than 18 years of age.
• Has a known allergy to any ester based anesthetics including cocaine HCl, procaine, tetracaine, chloroprocaine, dibucaine, or benzocaine amide based anesthetic allergies are NOT exclusionary. Amide based anesthetics are : lidocaine, mepivicaine, bupivicaine, levobupivicaine, ropivicaine, etidocaine, prilocaine, and articaine.
• Use of any enzyme-modifying drugs, including strong inhibitors of cytochrome P450 (CYP) enzymes (such as cimetidine, fluoxetine, quinidine, erythromycin, ciprofloxacin, fluconazole, ketoconazole, diltiazem and HIV antivirals) and strong inducers of CYP enzymes (such as barbiturates, carbamazepine, glucocorticoids, phenytoin, rifampin and St John's Wort), in the previous 28 days before day 1 of this study.
• The use of amphetamines, methylphenidate or other stimulant prescription and nonprescription products such as pseudoephedrine, bronchial inhalers containing sympathomimetics (epinephrine or other beta-receptor agonist) or herbal products in the 7 days prior to screening or has a need to use these drugs during the course of the study.
• Use of any Seratonin uptake inhibitor/Serotonin-norepinephrine reuptake inhibitors, antidepressants or tricyclic antidepressant up to7 days or 5 half-lives (whichever is longer) prior to screening or has a need to use these drugs during the screening period and throughout the time period of the trial.
• Use of Monoamine Oxidase Inhibitor drugs up to 14 days prior to screening or has a need to use these drugs during the screening period and throughout the time period of the trial.
• GI abnormalities
• History of hepatitis (for healthy control subjects only)
• Elevated aspartate aminotransferase/alanine aminotransferase /bilirubin (for healthy control subjects only),
• HIV
• Excessive use of alcohol/tobacco/caffeine.
• Has previously received study drug.
• Has a history of abuse of controlled substances, nasal or otherwise, or has damage to the nasal space, that in the opinion of the investigator might interfere with the ability to absorb RX0041-002.
• Has severely traumatized mucosa or sepsis in the nasal cavity.
• Has participated in an investigational study or received an investigational drug within 30 days preceding the randomization.
• Is a pregnant or nursing mother.
• Has a positive pregnancy test at Screening or Day -1.
• Has a history of seizure, with the exception of febrile seizures.
• Has symptomatic cardiovascular disease.
• Has a history of or currently suffers from hyperthyroidism.
• Has a known personal or family history of hereditary pseudocholinesterase deficiency. Study participants will be screened by asking about personal or family history of anesthetic reaction, anesthetic death, and previous diagnosis of psuedocholinesterase deficiency in a relative or personally. Subjects identified with pseudocholinesterase deficiency are at risk for delayed recovery with certain anesthetics (e.g. succinylcholine and ester-based anesthetics).
• Has a known personal or family history of pheochromocytoma. Study participants will be specifically asked if they have been treated for a pheochromocytoma previously or if they have a family member who has been diagnosed with pheochromocytoma (since 10% of these are familial).
• Has a known personal or family history of adrenal tumor.
• Clinically significant ECG abnormalities, based upon the impression of the investigator.
