Bull points
- we continue to believe in general that oxybates will be complementary to orexins. And then when we lay out the differentiation of ZyWave with both low sodium being the only low sodium oxybate on the market and flexible dosing, we see that HCPs and patients alike continue to choose the low sodium based on the underlying cardiovascular conditions that often exist and the propensity to develop cardiovascular conditions on high sodium oxibates.
- we have very, very extensive and robust data, not only with ZyWave, but in the Oxibate field in general, and many, many years of patient experience showing that when administered at night, and of course it's washed out by the time patients wake up in the morning, there's a very significant and clinically meaningful impact on nighttime sleep, improving key parameters like total sleep time, reducing awakenings after sleep onset dramatically, improving deep sleep, consolidating REM sleep.
- we have an exciting pipeline and are making substantial progress on key programs, with additional milestones expected this year.
Bear points
- What we haven't seen is orexins improving meaningfully nighttime sleep.
- we haven't seen a lot of data around that first part of the night where residual exposure to orexins might actually be disrupting sleep.
- Rylase net product sales were approximately $101 million in the second quarter of 2025, a decrease of 7% year over year.
