**FDA Refusal to File Impact**: Harmony Biosciences recently received a Refusal to File (RTF) letter from the FDA regarding Pitolisant for excessive daytime sleepiness in patients with idiopathic hypersomnia (IH). Such a setback can significantly impact stock prices, as it raises concerns about the drug's market potential and the company's ability to navigate regulatory hurdles.

**Future Plans**: Despite the FDA's decision, the company remains focused on the future. The CEO's announcement of initiating a Phase 3 registrational trial for an enhanced formulation, Pitolisant HD, indicates ongoing development efforts. This may appeal to investors looking for long-term growth potential, although the target PDUFA date of 2028 adds a layer of uncertainty.

**Market Context**: The current state of the company's pipeline, especially with setbacks like the RTF letter, may lead investors to reassess the value of their stock. The combination of regulatory challenges and the delay in bringing products to market could result in short-term volatility in stock prices.
