Despite the FDA approval of Zenrelia, Elanco Animal Health (ELAN) did not see a significant increase in its stock price on September 19, 2024, and actually experienced a decrease on September 20, 2024. There are several reasons for this outcome:
- Market Perception and Analyst Ratings: According to the analysis by Piper Sandler, the stock rating remained Neutral with a price target of $16.00, which suggests that the market did not anticipate a significant price surge based on the FDA approval1.
- Label Warnings and Efficacy Concerns: The FDA approval of Zenrelia came with a boxed warning regarding the need to discontinue the drug 28 days to 3 months before any vaccination, which could potentially slow down market penetration. Additionally, there were concerns about the actual efficacy of Zenrelia compared to the market incumbent JAK inhibitor, Apoquel, as indicated by a higher placebo effect and a lower rate of clinical remission of itch in the FDA study12.
- Investor Expectations: Despite the approval, investor expectations for Zenrelia over the next two years were already elevated, which could imply that the market had already priced in the potential of the drug3.
- Competitive Market Dynamics: The canine dermatology market is competitive, and Zenrelia faces competition from established treatments like Apoquel. The market response to Zenrelia may be influenced by its positioning relative to these competitors4.
- Short-Term Impact: The stock price movement may also reflect short-term market dynamics, where the initial approval news was already factored into the stock price, and any subsequent price target adjustments or market perceptions might have led to a decrease1.
In conclusion, while the FDA approval of Zenrelia was a significant milestone for Elanco, the stock price increase was not substantial due to a combination of factors including market perception, label warnings, efficacy concerns, investor expectations, competitive dynamics, and short-term market impacts.
