Safety, Tolerability, and Efficacy Study of LFX453 in Actinic Keratosis Patients

December 9, 2020 updated by: Novartis Pharmaceuticals

A Randomized, Vehicle Controlled, Active Comparator, Parallel Group Study to Evaluate Safety, Tolerability and Preliminary Efficacy of Topical LFX453 Formulations in Patients With Actinic Keratosis

This is a randomized, vehicle controlled, active comparator, parallel group, study with a total duration of 24 weeks including screening and follow-up. Study drug is applied topically for 2 cycles of 4 week treatment, separated by 4 weeks off-treatment. Assessors of study endpoints are blinded to treatment allocation.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Key Inclusion Criteria:

  • Male patients, and female patients of non-childbearing potential, age ≥ 18 to ≤ 75 years (at the time of the screening visit), and in general good health as determined by past medical history, physical examination, vital signs, electrocardiogram, and laboratory tests at screening
  • Patients with at least five clinically typical, visible or palpable non-hyperkeratotic AK lesions within a contiguous area of 25 cm2, or within 2 areas for a maximum total of 25cm2, on the face (at least 2 cm from the periocular areas, lips, nares and ears) and/or balding scalp
  • Presence of at least one additional visible or palpable non hyperkeratotic AK lesion outside of the selected area amenable to the collection of a skin biopsy, and located at least at 2 cm from the limits of the area to receive treatment
  • Male patients had to agree to use adequate contraception for the duration of the study.

Key Exclusion Criteria:

  • Known hypersensitivity to any constituents of the study drugs (including local anesthetics if consenting to biopsies) or known allergies to imiquimod or to drugs of similar chemical classes or history of serious allergic reaction.
  • Presence of atopic dermatitis, eczema, psoriasis, rosacea or other possible confounding skin conditions on face or balding scalp even outside of the treatment area.
  • Invasive tumors within the treatment area, e.g., merkel cell carcinoma, melanoma, squamous cell carcinoma (SCC), basal cell carcinoma, the latter being accepted if completely surgically removed.
  • Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant.
  • History of hypertrophic scarring.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
