Praxis Precision Medicines, Inc. is valued as a pure-play on ulixacaltamide's commercial launch in essential tremor, with pipeline optionality limited. I maintain a cautious Hold rating, as PRAX trades above my fair value estimate of $223.73 versus a current share price of $265. Key risks include real-world persistence, payer step edits, and competition from cheap off-label generics, which could materially limit ulixacaltamide's addressable market and duration.
