Abstract

Therapeutic formulations and methods for inhibiting amyloid deposition in a subject, whatever its clinical setting, are described. Therapeutic formulations and methods for preventing or treating amyloidosis and/or amyloid-related disease are also described.

Claims

1. An oral formulation comprising an active agent which is 3-amino-1-propanesulfonic acid or a pharmaceutically acceptable salt thereof and a pharmaceutically acceptable vehicle,

wherein, when the formulation is administered in a dose of 50 mg of the active agent, a mean plasma concentration profile having a mean AUC_∞

of about 1396 ng▪

h/mL±

20%, and a mean Cmax of about 310 ng/mL±

20% is achieved, and

wherein the formulation is effective to inhibit or prevent amyloid deposition and/or treat or prevent an amyloid-related disease.

4. A formulation of claim 1, wherein the formulation is in a form effective for osmotic release, pulsatile release, sustained release, controlled release, extended release or delayed release.

5. A method of treating amyloidosis, inhibiting or preventing amyloid deposition and/or treating or preventing an amyloid-related disease in a patient in need thereof comprising administering an oral formulation of claim 1.

6. The method of claim 5, further comprising administering another therapeutic agent.

7. The method of claim 6 wherein the other therapeutic agent is a cholinesterase inhibitor or an NMDA receptor antagonist.

15. A formulation of claim 1, wherein the formulation is in a form for release modified from an immediate release form.

2. An oral formulation comprising an active agent which is 3-amino-1-propanesulfonic acid or a pharmaceutically acceptable salt thereof and a pharmaceutically acceptable vehicle,

wherein, when the formulation is administered in a dose of 100 mg of the active agent, a mean plasma concentration profile having a mean AUC_∞

of about 2569 ng▪

h/mL±

20%, and a mean Cmax of about 618 ng/mL±

20% is achieved, and

wherein the formulation is effective to inhibit or prevent amyloid deposition and/or treat or prevent an amyloid-related disease.

3. An oral formulation comprising an active agent which is 3-amino-1-propanesulfonic acid or a pharmaceutically acceptable salt thereof and a pharmaceutically acceptable vehicle,

wherein, when the formulation is administered in a dose of 150 mg of the active agent, a mean plasma concentration profile having a mean AUC_∞

of about 3418 ng▪

h/mL±

20%, and a mean Cmax of about 624 ng/mL±

20% is achieved, and

wherein the formulation is effective to inhibit or prevent amyloid deposition and/or treat or prevent an amyloid-related disease.

8. A method of lessening gastrointestinal side effects in a human patient which occur from orally administering an active agent which is 3-amino-1-propanesulfonic acid or a pharmaceutically acceptable salt thereof, comprising administering said agent according to a schedule wherein an initial dose is administered and the dose is increased over time to a higher dose which inhibits or prevents amyloid deposition and/or treats or prevents an amyloid-related disease.

9. The method of claim 8, wherein the 3-amino-1-propanesulfonic acid or a pharmaceutically acceptable salt thereof, is administered in an initial dose for one month followed by an increased dose the second month, which is optionally maintained throughout the treatment, or is followed by an increased dose for the third month which is maintained throughout the treatment.

10. The method of claim 8, wherein the patient is administered 50 mg B.I.D. doses in the first month and 100 mg B.I.D. doses in the second and followings months of treatment.

11. The method of claim 8, wherein the patient is administered 50 mg B.I.D. doses in the first month, 100 mg B.I.D. doses in the second month and 150 mg B.I.D. doses in the third and following months of treatment.

12. A method for lowering the level of Aβ

₄₂ in the cerebrospinal fluid of a patient which comprises orally administering to the patient an active agent which is 3-amino-1-propanesulfonic acid or a pharmaceutically acceptable salt thereof, in a formulation which, when administered in a dose of 100 mg of the active agent, achieves a mean plasma concentration profile having a mean AUC_0-t of about 2467 ng▪

h/mL±

20% and, a mean Cmax of about 618 ng/mL±

20%.

13. A method for treating and/or preventing Alzheimer'"'"'s disease in a patient which comprises orally administering to the patient an active agent which is 3-amino-1-propanesulfonic acid or a pharmaceutically acceptable salt thereof, in a formulation which, when administered in a dose of 100 mg of the active agent, achieves a mean plasma concentration profile having a mean AUC_0-t of about 2467 ng▪

h/mL±

20% and, a mean Cmax of about 618 ng/mL±

20%.

14. A method for stabilizing cognitive function or decreasing the rate of decline in cognitive function, as assessed by Clinical Dementia Rating (CDR) scale, Mini-mental State Examination (MMSE), or Alzheimer'"'"'s Disease Assessment Scale-Cognitive Subscale (ADAS-Cog), in a patient which comprises orally administering to the patient an active agent which is 3-amino-1-propanesulfonic acid or a pharmaceutically acceptable salt thereof, in a formulation which, when administered in a dose of 100 mg of the active agent, achieves a mean plasma concentration profile having a mean AUC_0-t of about 2467 ng▪

h/mL±

20% and, a mean Cmax of about 618 ng/mL±

20%.

16. An oral formulation for lessening gastrointestinal side effects in a human patient which occur from administration of an active agent which is 3-amino-1-propanesulfonic acid or a pharmaceutically acceptable salt thereof in an immediate release dosage form, comprising an effective amount of said agent to treat amyloidosis, inhibit or prevent amyloid deposition and/or treat or prevent an amyloid deposition-related disease and a pharmaceutically accetpable vehicle, wherein the formulation results in lesser side effects in comparison to those of said immediate release dosage form, and wherein the formulation, when administered in a dose of 100 mg of the active agent, achieves a mean plasma concentration profile having a mean AUC_0-t of about 2467 ng▪
