A Relative Bioavailability Study of FOR-6219 in Capsule and Tablet Formulations

• Status: Completed
• Trial end date: 2021-01-16
• Target enrollment: 0
• Participant gender: Female

Summary

This is a phase 1, randomised, open-label, three-way, three-period, crossover relative bioavailability study to assess the single-dose pharmacokinetics of FOR-6219 in capsule and tablet formulations in postmenopausal women. The effect of high-fat food on the pharmacokinetics of the tablet formulation will also be evaluated. A total of twelve, post-menopausal women, will be randomised to receive a single oral dose of FOR-6219 in three treatment periods: capsule formulation (fasted); tablet formulation (fed); tablet formulation (fasted)

Criteria

Inclusion Criteria:

• Female participants between 45 and 65 years (inclusive) at screening

• Female participants must be either naturally (spontaneously) post-menopausal: Natural (spontaneous) postmenopause is defined as being amenorrheic for at least 12 months without an alternative medical cause with a screening follicle stimulating hormone level >25.8 IU/L and 17β-oestradiol serum levels less than 183 pmol/L (or the local laboratory levels for post-menopause) OR Must have had a bilateral oophorectomy/bilateral salpingo-oophorectomy. Hysterectomised women can be included only if they have had bilateral oophorectomy.

• Participants not taking hormone replacement therapy (HRT).

• Has a body weight between 50kg and 100kg inclusive and a body mass index (BMI) between 18.5-30.0 kg/m^2 inclusive.

• Satisfactory medical assessment with no clinically significant or relevant abnormalities as determined by medical history, physical examination, vital signs, 12-lead ECG, and clinical laboratory evaluation (haematology, biochemistry, coagulation and urinalysis) that is reasonably likely to interfere with the participant's participation in or ability to complete the study as assessed by the investigator.

• Ability to provide written, personally signed, and dated informed consent to participate in the study, in accordance with the ICH Good Clinical Practice (GCP) Guideline E6 (R2) (2016) and applicable regulations, before completing any study-related procedures.

• Ability to swallow three capsules and tablets at a time or (consecutively) one capsule at a time.

• An understanding, ability, and willingness to fully comply with study procedures and restrictions.

Exclusion Criteria:

• Post-menopausal women with less than 12 months amenorrhoea, or women with amenorrhoea due to other medical causes.

• Current or recurrent disease (e.g., cardiovascular, haematological, neurological, endocrine, immunological, renal, hepatic or gastrointestinal or other conditions) that could affect the action, absorption, or disposition of FOR-6219, or could affect clinical laboratory evaluations.

• Current or relevant history of physical or psychiatric illness that are not stable or may require a change in treatment, use of prohibited therapies during the study or make the participant unlikely to fully comply with the requirements of the study or complete the study, or any condition that presents undue risk from the investigational product or study procedures.

• Any other significant disease or disorder which, in the opinion of the Investigator, may either put the participant at risk because of participation in the study may influence the result of the study, or the participant's ability to participate in the study.

• The history or presence of any of the following cardiac conditions: known structural cardiac abnormalities; family history of long QT syndrome; cardiac syncope or recurrent, idiopathic syncope; exercise-related clinically significant cardiac events.

• Any clinically significant abnormalities in rhythm, conduction or morphology of resting ECG or clinically important abnormalities that may interfere with the interpretation of QTc interval changes.

• Has vital signs consistently outside of the following normal range. Supine blood pressure (after at least 5 minutes of supine rest): Systolic blood pressure: 90 - 140 mmHg, Diastolic blood pressure: 40 - 90 mmHg.

• Positive test for Hepatitis B surface antigen (HBsAg), Hepatitis C antibody (HCV Ab), or human immunodeficiency virus antibody (HIV Ab) at screening.

• Evidence of pregnancy

• Any other abnormal findings on vital signs, ECG, physical examination or laboratory evaluation of blood and urine samples that the Investigator judges as likely to interfere with the study or pose an additional risk in participating.

• Positive test results for alcohol or drugs of abuse.

• History or clinical evidence of substance and/or alcohol abuse within the two years before screening.

• Use of tobacco in any form (e.g., smoking or chewing) or other nicotine-containing products in any form (e.g., gum, patch, electronic cigarettes) within three months prior to the planned first day of dosing.

• Has used any medication that is either an inhibitor or inducer of CYP3A4 within 28 days or 10 half-lives (whichever is longer) prior to the planned first day of dosing. Additionally, participants must not have consumed other substances known to be potent inhibitors or inducers of cytochrome P450 (CYP P450s) in the two weeks before the planned first study drug administration.

• Has used any other prescription or over-the-counter medication (including herbal or homeopathic preparations; excluding vitamin/mineral supplements and occasional paracetamol) within 14 days or 10 half-lives (whichever is longer) prior to the planned first day of dosing that the Investigator judges is likely to interfere with the study or pose an additional risk in participating.

• Consumption of herbal remedies or dietary supplements containing St. John's Wort in the 3 weeks before the planned Day 1 of the dosing period.

• Has received an investigational product or been treated with an investigational device within 90 days prior to first drug administration and will not start any other investigational product or device study within 90 days after last study drug administration.

• Known or suspected intolerance or hypersensitivity to the investigational product, any closely related compound, or any of the stated ingredients.

• History of significant allergic reaction (anaphylaxis, angioedema) to any product (food, pharmaceutical, etc).

• Has donated or lost 400 mL blood or more within the last 16 weeks preceding the first day of dosing.

• Has a mental incapacity or language barriers precluding adequate understanding, cooperation, and compliance with the study requirements.

• An inability to follow a standardised diet and meal schedule or inability to fast, as required during the study.

• Prior screen failure (where the cause of the screen failure is not deemed to be temporary), randomisation, participation, or enrolment in this study. Participants who initially failed due to temporary non-medically significant issues are eligible for rescreening once the cause has resolved.
