Basilea is currently working on novel derivatives of macrolides, a well-established
class of antibiotics that inhibit protein biosynthesis.
Macrolides are generally well tolerated, and for this reason are also widely used to
treat infections in children. Macrolides also possess beneficial side effects such as
immuno-modulatory activity, which may contribute to their therapeutic success.
BAL19403 was selected as the first clinical candidate from Basilea
research that advanced into preclinical development as a
potential topical treatment for acne and rosacea. It belongs to a new class of
antibacterial macrolides with excellent activity against antibiotic-resistant
propionibacterium acnes and potent anti-inflammatory properties.
About Acne vulgaris and Rosacea
Both, Acne and Rosacea are common inflammatory diseases of the skin.
Acne vulgaris is a multi-factorial disorder of the sebaceous (grease-producing)
glands frequently occurring in adolescence and young adulthood. Besides follicular
plugging and increased sebum production, acne results from proliferation of the skin
bacterium Propionibacterium acnes, which colonizes the hair follicles, induces
secretion of inflammatory factors and thereby worsens the initial disease.
Rosacea occurs predominantly in middle-aged patients and is largely of unknown
etiology. Rosacea is characterized by pustular lesions on the face and a strong
inflammatory response that sometimes leads to a characteristically enlarged nose
(rhinophyma).
