Bemotrizinol UV Filter Part 1 Clinical PK Evaluation in Topical MUsT Study

Completed · Phase 1

Conditions studied: Absorption; Chemicals, Sunscreening Agents

In brief

This will be a single clinical study conducted in 2 parts (Part 1: pilot study and Part 2: pivotal study). Part 1 is an open-label, 1-arm study in 14 healthy adult subjects with the following primary objectives: * Primary: To explore whether the active component, bemotrizinol (BEMT), is absorbed from a high-penetrating sunscreen formulation including 6% BEMT into the systemic circulation when applied under maximal-use conditions. * Secondary: To obtain information needed for a successful pivotal study such as preliminary pharmacokinetic (PK) data, validation of study and analytical procedures, and the number of subjects needed. Part 2 is an open-label, randomized, 3-arm study in 42 healthy adult subjects with the following objective: • Primary: To assess the systemic absorption and pharmacokinetics of BEMT from 3 market image sunscreen formulations under maximal-use conditions.

• Male subject agrees to refrain from sexual activity with female partners unless an acceptable method of birth control is used by both partners. Male subject is surgically sterile or agrees to use barrier contraception (condom with spermicide), and refrain from sperm donation, from the first application of study drug until 90 days after the last application of study drug.

• Subject has any underlying disease or surgical or medical condition (e.g., cancer, human immunodeficiency virus [HIV], severe hepatic or renal impairment) that could put the subject at risk or would normally prevent participation in a clinical study.
• Subject has known or suspected allergies or sensitivities to any components of the sunscreen formulation.
• Subject has clinical laboratory test results (hematology and serum chemistry) at Screening that are outside the reference ranges provided by the clinical laboratory and considered clinically significant by the investigator.

• Subject has a positive test result at Screening for HIV type 1 or 2 antibody, hepatitis C virus antibodies, or hepatitis B surface antigen.
• Subject is unable or unwilling to undergo multiple venipunctures for blood sample collection because of poor tolerability or poor venous access.
• Subject has used any product(s) containing bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT), such as sunscreen products, hand or body moisturizing lotion, makeup or foundation, hair care product, lip balm, or lipstick within 14 days before Check in (Day -1) and at any time before End-of-Study procedures.
