The Pediatric Trials Network (PTN) has enrolled the last patient in its Efficacy, Safety and Pharmacokinetics of Topical Timolol in Infants with Infantile Hemangioma (TIM01) study.

In the study, approximately 110 participants will be randomized to either 0.25% or 0.5% timolol for 180 days to determine the most appropriate dosing level for children younger than three months old.

Timolol is a beta blocker that has increasingly been used for the treatment of Infantile Hemangiomas (IH), commonly called “strawberry” birthmarks, on infants’ skin. The popularity of timolol is likely due to its perceived safety as a topical drug. However, little is known regarding the safety of topical timolol’s use.

Additional updates will be shared upon the conclusion of the study in 2020.
