NCT ID: NCT03665194

Last Updated: 2019-02-04

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 32 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2018-06-06
• Study Completion Date: 2018-09-12

Brief Summary

This is a randomised, double blind placebo controlled Phase I study which will assess the safety, tolerability and PK of Cortexolone 17α-propionate (and its metabolites), and its effects on the QTc interval when administered as multiple doses to healthy adult volunteers. Volunteers will receive a morning and evening dose (12 hours apart) of 225 mg (3 mL Cortexolone 17α-propionate applied topically as a 7.5 % solution (75 mg in 1 mL), giving a total daily dose of 450 mg (6 mL) per individual.

Detailed Description

Thirty-two volunteers will be enrolled and evaluated (i.e. complete the study). Subjects will be dosed in four groups of eight (purely for logistical reasons relating to the procedure times expected with dosing and ECG). Volunteers will receive either the active drug or matching placebo in a 3:1 ratio. Therefore within each cohort, six volunteers will receive the active drug and two will receive matching placebo.

Volunteers will be screened within 20 days prior to entering the study on Day -1. Each volunteer will receive verbal and written information followed by signing of the ICF prior to any screening procedures taking place. Volunteers will be admitted to the study unit on Day -1, dosed twice daily on Days 1-3 and once on Day 4 (morning dose only). They will be discharged on Day 6 and will have a telephone follow-up on Day 14. If they report any relevant Adverse Event (AE) they will be invited to attend the unit for an outpatient visit as close to Day 14 as is possible.

Eligibility Criteria

Inclusion Criteria

1. Male or female subjects ≥18 and ≤40 years at the date of signing informed consent which is defined as the beginning of the Screening Period.

2. Subjects must have a body mass index (BMI) between 18.0-25.0 kg/m² inclusive.

3. Subjects must be bald, have a shaved head, or be willing to have their head shaved.

4. Female subjects who are either: (a) Non-childbearing potential, e.g. post-menopausal (as defined as amenorrhoea for at least 12 months with no alternative medical cause) or permanently sterile (permanent sterilisation methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy) OR (b) Childbearing potential AND (if heterosexually active) agree to use at least one form of highly effective contraception as defined below, starting at least one menstrual cycle before first study drug administration and continuing until at least 3 months after the end of the systemic exposure of the study drug.

Highly effective contraceptive methods for females are as follows:

• Combined (oestrogen- and progestogen-containing) hormonal contraception associated with inhibition of ovulation as follows:

• Oral
• Intravaginal
• Transdermal
• Progestogen-only hormonal contraception associated with inhibition of ovulation as follows: o Oral

• Injectable
• Implantable
• Intrauterine device (IUD)
• Intrauterine hormone-releasing system (IUS)
• Bilateral tubal occlusion
• Male partner vasectomised (with documented evidence of azoospermia if possible)

5. Male subjects, if heterosexually active and with a female partner of childbearing potential or a pregnant or breastfeeding partner, must agree to use barrier contraception (male condom) for the treatment period and for at least three months after the end of the systemic exposure of the study drug. Female partners of male subjects who are of childbearing potential must use one or more forms of highly effective contraception as defined above, starting at least one menstrual cycle before (their male subject's) first study drug administration and continuing until at least three months after the end of their male partner's systemic exposure to the study drug.

For male subjects who have had a vasectomy (with documented evidence of azoospermia if possible) and agree to use a barrier method (male condom) for the stated time period, no additional contraceptive method is required by their female partner.

6. Subjects must agree not to donate sperm or ova from the time of the first administration of study medication until 3 months after the end of the systemic exposure of the study drug.

7. 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 subject's participation in or ability to complete the study as assessed by the investigator.

8. 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 (1996) and applicable regulations, before completing any study-related procedures.

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

Exclusion Criteria

1. Current or recurrent disease (e.g., cardiovascular, haematological, neurological, endocrine, renal, liver, gastrointestinal, hepatic or other conditions) that could affect the action, absorption, or disposition of Cortexolone 17α-propionate, or could affect clinical assessments or clinical laboratory evaluations.

2. Current or relevant history of any physical or psychiatric illness that may require treatment or make the subject 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.

3. Any other significant disease or disorder which, in the opinion of the investigator, may put the subject at unacceptable risk because of participation in the study, may influence the result of the study, or may affect the subject's ability to participate in the study.

4. History of any pathology affecting the skin such as eczema, psoriasis or any skin hypersensitivity.

5. Have tattoos on the scalp or thigh which would affect the area for topical application of the trial drug.

6. 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.

7. 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. This includes subjects with any of the following (at screening, Day -1 or pre-dose of Day 1):

• Sinus node dysfunction.
• Clinically significant PR (PQ) interval prolongation.
• Intermittent second or third degree AV block.
• Complete bundle branch block.

Subjects with borderline abnormalities may be included if the deviations do not pose a safety risk, and if agreed between the appointed Cardiologist and the investigator.

8. Has vital signs outside of the following normal range at screening, Day -1 or Day 1 predose:

1. Blood pressure (BP):
