Cnstyx (MSF) delivers targeted brain therapy without the peripheral toxicity that's
held back cholinergic treatment for 30 years. No $26K infusions. No GI devastation.
Just a daily oral pill.
The Current Treatment Landscape is Failing Families
Existing cholinesterase inhibitors (Aricept, Exelon, Razadyne) cause debilitating GI side effects because they hit peripheral acetylcholinesterase. Monoclonal antibodies cost $26,000/year and require IV infusion centers most families can't access.

Targets brain acetylcholinesterase while sparing peripheral systems. The selectivity ratio changes everything.

No more nausea, vomiting, or diarrhea that forces patients off treatment. We removed the toxicity ceiling.

A daily pill. No infusion centers. No $26K barrier. Treatment that can actually reach the 6.9 million who need it.
| Factor | Traditional AChE Inhibitors | Monoclonal Antibodies | Cnstyx (MSF) |
|---|---|---|---|
| CNS Selectivity | Low — hits peripheral systems | N/A — different mechanism | High — brain-targeted |
| GI Side Effects | Severe — 50%+ discontinuation | Moderate | Minimal — peripheral-sparing |
| Administration | Oral | IV Infusion required | Oral — daily pill |
| Annual Cost | ~$200–400 | ~$26,000 | Small molecule economics |
| Market Exclusivity | Generic — no protection | Patent protected | NCE Status — 5-year exclusivity |
| Adherence Barrier | High — side effects drive dropout | High — infusion access | Low — tolerable oral dosing |
