TP-04: An investigational therapeutic being studied for the potential treatment of papulopustular rosacea
TP-04 is a topical, aqueous gel formulation of lotilaner in development for the potential treatment of papulopustular rosacea (PPR).1
According to the National Rosacea Society, approximately 16 million people in the US are affected by rosacea,2 a chronic skin disease characterized by facial redness, inflammatory lesions, burning, and stinging. PPR, estimated to occur in 18% to 28% of patients with rosacea, can result in redness, swelling, and/or pus-filled bumps.3-7
Designed to potentially treat PPR and eradicate Demodex mites, which have been reported as highly prevalent in the skin of patients with rosacea, including those with PPR, and may play a key role in triggering inflammatory responses associated with the disease
A topical gel formulation of lotilaner, a well-characterized antiparasitic agent that paralyzes and kills Demodex mites by selectively inhibiting parasite-specific
gamma-aminobutyric acid–chloride channels
Currently being evaluated in a Phase 2a trial
Read about a chronic condition characterized by facial redness, flushing, and visible blood vessels.
