Outlook and guidance

• Partnering discussions for POLB 001 are active, supported by a clinical data package being built around TOPICAL.

• FDA pre-IND feedback clarified the nonclinical package, indication, Phase 3 design and endpoints; pivotal-trial initiation could follow TOPICAL through partnering.
