Treatments

What exists today, and what we are still building.

Each card is the same shape: what it is, how it works, who it is for, and what it does not do. None of this replaces a conversation with an NPC clinician. Companies behind these medicines, and the family organizations walking with us, are listed on Community.

FDA-approved

Miplyffa (arimoclomol)

The first FDA-approved medicine for NPC, taken with miglustat to help fragile NPC1 protein keep working.

FDA-approved

Aqneursa (levacetylleucine)

A stand-alone oral medicine that helps lysosomes and brain cells work better.

Used in NPC care

Miglustat

An older substrate-reduction therapy that slows the buildup of certain lipids, and is now paired with Miplyffa.

Investigational

Adrabetadex

Beren Therapeutics’ cyclodextrin, given into the spinal fluid. Expanded access has been a lifeline for many children with NPC, and an application is under FDA review. It is not Trappsol Cyclo.

Investigational · Phase 3

Trappsol Cyclo

Cyclo Therapeutics’ cyclodextrin, given in a vein. It is in the Phase 3 TransportNPC study. Same broad idea as adrabetadex, different product and delivery.

Investigational · Phase 3

Nizubaglustat

Azafaros’ oral medicine in the global Phase 3 NAVIGATE study. A brain-penetrant substrate-reduction approach. It is not miglustat, and it is not approved.

In research

mRNA gene therapy

The Life 4 Liam approach: teach the cell to make the missing NPC1 protein using messenger RNA.

Essential care

Supportive care

Therapy, nutrition, seizure care, school support, and daily help are part of treatment — not extras.

Research

AAV gene therapy

Researchers can pack a working NPC1 gene into an engineered adeno-associated virus (AAV) capsid. That is gene addition — a different tool from the mRNA and prime-editing path Life 4 Liam funds. One named program is Apertura’s TfR1 capsid, studied with the NIH. It is not in patients yet.

Research

DL33

Meizon’s small-molecule candidate for NPC. Manufacturing and animal toxicology are the current work, toward a possible Phase 1. It is not in patients.
