Summary

The purpose of this study is to determine whether albaconazole tablets and albaconazole capsules (single 400mg dose) act in the body in the same way over a period of time.

• Phase: Phase 1
• Accepts Healthy Volunteers?: Accepts Healthy Volunteers

Details

• Lead Sponsor: Stiefel, a GSK Company
• Collaborator: GlaxoSmithKline
• Treatments: Albaconazole

Criteria

Inclusion Criteria:

• Capable of understanding and willing to provide signed and dated written voluntary informed consent (and any local or national authorization requirements) before any protocol specific procedures are performed.

• Male or female aged from 18 to 45 years at time of consent and at time of first dose.

• A body mass index (BMI) between 18.5 and 30 kg/m2.

• Able to complete the study and to comply with study instructions.

• Free of clinically significant disease as determined by history, physical examination, and laboratory testing.

• The subject is a non-smoker or ex-smoker. If a subject is an ex smoker, he/she must not have used nicotine for at least 6 months before first dose.

• The screening and baseline laboratory parameters must be within normal ranges unless agreed as not clinically relevant by the principal investigator and the sponsor. Alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase, and total bilirubin values should be lower than 1.5 times the upper normal limit at screening.

• The subject will have negative results for the following tests at screening:

• Hepatitis B surface antigen (HBsAg)

• Hepatitis B core antibodies (HBcAc)

• Anti-hepatitis C virus (Anti-HCV)

• Human immunodeficiency virus (HIV) antibody test

• Urine drug screen

• Sexually active females of childbearing potential participating in the study must agree to use a medically acceptable method of contraception while receiving protocol-assigned product and until 30 days following the last dose of the study product. A woman of childbearing potential is defined as one who is biologically capable of becoming pregnant; including perimenopausal women who are less than 2 years from their last menses. Acceptable contraceptive methods include the following:

• Hormonal contraception, including oral, injectable, or implantable methods started at least 2 months prior to screening. If hormonal contraception was started less than 2 months prior to screening, then a form of nonhormonal contraception should be added until the third continuous month of hormonal contraception has been completed.

• Two forms of reliable nonhormonal contraception, to include the use of either an intrauterine device plus a reliable barrier method or 2 reliable barrier methods. Reliable barrier methods include condoms or diaphragms. A cervical cap is also a reliable barrier method, provided that the female subject has never given birth naturally. The combined use of a condom and spermicide constitute 2 forms of acceptable nonhormonal contraception, provided that they are both used properly. The use of spermicide alone and the improper use of condoms are inferior methods of contraception. Subjects with surgical sterilization, including tubal sterilization or partner's vasectomy, must use a form of nonhormonal contraception. A barrier method or sterilization plus spermatocide are acceptable.

• Women who are not currently sexually active must agree to use a medically accepted method of contraception should they become sexually active while participating in the study. Male subjects and/or their partners must use a medically acceptable form of contraception

Exclusion Criteria:

• Female who is pregnant (positive pregnancy test), trying to become pregnant, or breast feeding.

• Received any investigational drug within 30 days of study day 1 or who are scheduled to receive an investigational drug other than the study product during the study.

• Used prescription drug therapy, over the counter (nonprescription) medications, recreational drugs, or herbal products within 30 days of dosing, unless agreed as not clinically relevant by the principal investigator and sponsor.

• Participated in a previous study of the same study product.

• Currently using any medication that, in the opinion of the investigator, may affect the evaluation of the study product or place the subject at undue risk.

• Currently suffering from any disease or condition that, in the opinion of the investigator, may affect the evaluation of the study product or place the subject at undue risk.

• Has a history of anemia, iron deficiency, or iron depletion.

• Has a history of any condition possibly affecting absorption of drug (eg, peptic ulcer disease, gastrectomy, intestinal malabsorption).

• Considered immunocompromised.

• History of drug, prescription medicine, or alcohol abuse within the past 2 years.

• Has a history of known or suspected intolerance to any of the ingredients of the study products.

• Has known drug allergies.

• Has a clinically relevant history or presence of respiratory, gastrointestinal, renal, hepatic, hematological, lymphatic, neurological, cardiovascular, psychiatric, musculoskeletal, genitourinary, immunological, dermatological, or connective tissue diseases or disorders.

• Intends to donate blood or blood components while receiving the study product or for the duration of the pharmacokinetic sampling period.

• Has donated blood or has had significant blood loss (≥250 mL) within 30 days before dosing or has donated plasma within 7 days before dosing.

• Has QT interval corrected for heart rate (Fridericia's correction formula) (QTcF) >450 ms or any ECG abnormality except for the following:

• Mild sinus bradycardia in younger, athletic subjects (heart rate down to 46 beats per minute allowed).

• Mild sinus arrhythmia.

• Mild first degree atrioventricular (A-V) block (P-R interval <0.23 sec).

• Mild right or left axis deviation.

• Incomplete right bundle branch block.

• Isolated left anterior fascicular block (left anterior hemiblock) in younger, athletic subjects.

• Early repolarization.

• Uncorrected QT interval or QT interval corrected for heart rate with Bazett's correction formula (QTcB) exceeding 450 ms, with a QTcF ≤450 ms.

• Considered unable or unlikely to attend the necessary visits.

• Employees of investigator/ clinical research organization or Stiefel involved in the study, or an immediate family member (partner, offspring, parents, siblings, or sibling's offspring) of an employee involved in the study.
