NCT01790165

Brief Summary

The aim of this study is to establish a clinical bridge to Lamisil® tablets by conducting a clinical pharmacokinetic (PK) study comparing the systemic exposure of a Lamisil® tablet with that of with TDT 067 under maximal use conditions. Under maximal use conditions in onychomycotic subjects, the aim is to confirm that there are significantly lower plasma levels of terbinafine and its major metabolites after a topical administration of TDT 067 for 28 days in comparison with a single oral 250 mg Lamisil® tablet.

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subjects must be between 18 and 65 years of age inclusive, of any race, and of either sex.
  • Male subjects only: Male subjects must use a reliable form of contraception during their participation in the trial and for 3 months after their last dose of study drug.
  • Female subjects only: Either of non-childbearing potential (i.e. either surgically sterilized or post menopausal) or must be using adequate contraception, have a negative pregnancy test prior to start of dosing, and must agree to continue to use this method of contraception until 3 months after the last dose. Acceptable contraceptive methods are oral contraceptive, IUD, or diaphragm with spermicide (unless anatomically sterile).
  • Subjects must be in good general health as confirmed by a medical history and physical examination.
  • Subjects must have 2 big toes with nails that have the potential to be clipped to provide nail samples.
  • Subjects must have clinically diagnosed distal subungual onychomycosis of the toenails; at least 5 nails in total must present with onychomycotic signs (onycholysis, subungual hyperkeratosis) including extensive involvement (≥50%) of both large nails and mycological confirmation (positive KOH microscopy) from 1 of the large nails.
  • Subject must sign a statement of informed consent.
  • Subjects must be able to understand the requirements of the study, abide by the restriction, and return for all of the required examinations

You may not qualify if:

  • Subjects lacking any toes.
  • Subjects with known hypersensitivity to terbinafine or any of the excipients in the TDT 067.
  • Subjects with symptomatic tinea pedis requiring treatment.
  • Subjects with any medical, neurological, or psychiatric conditions that in the opinion of the Investigator would make the subject unsuitable for enrollment onto the study.
  • Subjects with chronic or active liver disease, as well as subjects with elevated liver function tests above normal for the testing laboratory.
  • Subjects with renal impairment (creatinine clearance ≤50 mL/min).
  • Subjects who have received terbinafine tablets within 12 months or topical terbinafine (cream, solution/spray, or gel) within 6 months prior to screening visit; subjects who have received other oral antifungals within 4 months or other topical antifungals within 1 month.
  • Subjects who have participated within the previous 3 months in a clinical trial for the systemic or topical treatment of onychomycosis.
  • Subjects being treated with rifampin or cimetidine.
  • Subjects being treated with an investigational drug within 1 month prior to study start.
  • Subjects with psoriasis or history of psoriasis.
  • Subjects with nail dystrophy or other nail abnormalities other than onychomycosis.
  • Subjects with serious concurrent disease that might prevent completion of the trial.
  • Subjects who are pregnant (confirmed by pregnancy test) or who plan to become pregnant within the study timeframe or who are nursing.
  • Subjects who cannot read, understand, or sign the informed consent form or the instructions for applying and removing the study formulations.
