## Abstract

The present invention concerns a method for modulating the enzymatic activity of an enzyme, wherein said enzyme interacts with BMP, said method comprising the step of administering or inducing Hsp70, or a functional fragment or variant thereof, in a form suitable for allowing interaction between BMP and Hsp70, or said functional fragment or variant thereof, and thereby modulating the enzymatic activity of an enzyme interacting with BMP.

## Claims

### Claim 1

A method for treating Gaucher disease in a human comprising orally administering arimoclomol, or a pharmaceutically acceptable salt thereof, to the human.

### Claim 2 (depends on 1)

The method of claim 1, wherein the human is orally administered a daily dosage of arimoclomol, or a pharmaceutically acceptable salt thereof, of from about 1 ug to about 100 mg per kilogram of body weight.

### Claim 3 (depends on 2)

The method of claim 2, further comprising administering Miglustat to the human.

### Claim 4 (depends on 2)

The method of claim 2, further comprising administering enzyme replacement therapy to the human.

### Claim 5 (depends on 4)

The method of claim 4, wherein the enzyme replacement therapy is imiglucerase, agalsidase beta, or agalsidase alpha.
