Methods for treating lysosomal acid lipase deficiency in patients
View Patent ↗The present invention provides methods of treating LAL deficiency comprising administering to a mammal a therapeutically effective amount of lysosomal acid lipase with an effective dosage frequency. Methods of improving growth and liver function, increasing LAL tissue concentration, and increasing LAL activity in a human patient suffering from LAL deficiency are also provided.
1. A method of treating a human patient suffering from a lysosomal acid lipase (LAL) deficiency, comprising administering to the human patient safe and effective amounts of recombinant human LAL, wherein the administration of safe and effective amounts of recombinant human LAL comprises:
a) administering an initial dosage in an amount at 1 mg LAL/kg body weight one or more times, followed by
b) administering a subsequent dosage in an amount of 3 mg LAL/kg body weight one or more times.
2. The method of claim 1 , wherein plasma TG or LDL level of the human patient is reduced after administration of the one or more initial doses.
3. The method of claim 1 , wherein C max of the recombinant human LAL is about 200 ng to about 800 ng per mL of serum.
4. The method of claim 1 , wherein serum half-life of said recombinant human LAL is less than 30 min.
5. The method of claim 1 , wherein the recombinant human LAL has molecular weight of about 55 kD±2.
6. The method of claim 1 , wherein the time period between any dose and the next dose is about 5 days to about 30 days.
7. The method of claim 1 , wherein the time period between any dose and the next dose is about 7 days.
