Key Findings:
  • TLX101-Px received Orphan Drug and Fast Track designations.

  • UX111's resubmission includes updated long-term clinical data.
  • Zilganersen demonstrated stabilization in gait speed in clinical trials.
  • Zilurgisertib reduced new heterotopic ossification lesions in patients.
  • Aminolevulinic acid's indication may expand to superficial basal cell carcinoma.
  • Tiratricol's application is based on multiple clinical trials.
