$IXHL Technical Analysis of the Commentary
1. The Bohr Effect Argument is Mechanistically Sound: The author accurately notes how acetazolamide-induced mild metabolic acidosis decreases hemoglobin oxygen affinity, facilitating oxygen release to hypoxemic tissues during airway blockages. This explains why IHL-42X punches above its weight in tissue oxygenation metrics compared to purely mechanical/neuromuscular agents.
2. Regulatory Hierarchical Gating is a Critical Detail: Highlighting Apnimed's failure on the PROMIS-Fatigue endpoint is a crucial regulatory point. In FDA filings, once a hierarchical endpoint fails, subsequent p-values lose formal inferential validity, converting potential labeling claims into unproved secondary observations.
If DReAMzz delivers clean, non-skewed results that confirm or improve on the RePOSA signals (especially oxygen metrics + solid responder rates with good tolerability), it would be a meaningful de-risking event for IHL-42X.
