In cases of relapsed/refractory AL amyloidosis,

that sentence is delivered to ~38,500 patients in the U.S.

It's not good enough

to accept the status quo

I've been the doctor in that room. I've watched hope disappear, and I couldn't accept that months of suffering and subsequent death was "standard of care."

Ilya Rachman, MD PhD, Founder and CEO 5

When Your Immune System Becomes Your Killer

Normally, antibodies protect us like superheroes.

In AL amyloidosis, they go rogue,

turning into supervillains that flood organs with toxic light chains.

6

Painful and Unnecessary Months of Suffering

Healthy AL Amyloidosis

These toxic light chains clog up the heart, kidneys, and liver. Breathing becomes difficult, swelling begins, and even a short walk becomes challenging.

There are no drugs approved in relapsed/refractory AL amyloidosis.

Current investigators' choice agents produce an unsatisfactory reduction in AL amyloidosis disease markers (dFLC) with a low (0-10%) complete response (CR) rate

The Toxic Current Last-Ditch Effort

Only one 4-drug combination is approved for newly diagnosed patients only. Once relapse hits, there's nothing FDA approved.

Doctors often resort to off label drug uses, despite their limited efficacy.

We're developing a breakthrough with the goal of changing that hopeless sentence

Our mission is simple:

Create medicines that work without destroying the patient.

What that can mean for the patient…

Life becomes normal again.

A deep breath that reaches the bottom of the lungs. A walk that doesn't end at the mailbox.

A normal heartbeat again.
