Abstract

The present disclosure relates to improved methods of treatment with nirogacestat.

First claim

What is claimed:

1. A method for therapeutic treatment of desmoid tumor in a patient in need thereof comprising orally administering to the patient 150 mg (free base equivalent dose) of nirogacestat or a pharmaceutically acceptable salt thereof twice daily, wherein the method further comprises:
(a) upon the patient having Grade 3 or 4 diarrhea persisting for at least 3 days despite medical therapy, withholding the nirogacestat or pharmaceutically acceptable salt thereof until the diarrhea is resolved to no higher than a Grade 1 diarrhea or baseline and then restarting oral administration of the nirogacestat or pharmaceutically acceptable salt thereof at a dose of 100 mg (free base equivalent dose) twice daily;
(b) upon the patient having Grade 3 or 4 hypophosphatemia persisting for at least 3 days despite replacement therapy, withholding the nirogacestat or pharmaceutically acceptable salt thereof until the hypophosphatemia is resolved to no higher than a Grade 1 hypophosphatemia or baseline and then restarting oral administration of the nirogacestat or pharmaceutically acceptable salt thereof at a dose of 100 mg (free base equivalent dose) twice daily;
(c) upon the patient having Grade 3 or 4 hypokalemia despite replacement therapy, withholding the nirogacestat or pharmaceutically acceptable salt thereof until the hypokalemia is resolved to no higher than a Grade 1 hypokalemia or baseline and then restarting oral administration of the nirogacestat or pharmaceutically acceptable salt thereof at a dose of 100 mg (free base equivalent dose) twice daily;
(d) upon the patient having an ALT or AST of 3 to 5 times ULN, withholding the nirogacestat or pharmaceutically acceptable salt thereof until the ALT, AST, or both are resolved to less than 3 times ULN or baseline and then restarting oral administration of the nirogacestat or pharmaceutically acceptable salt thereof at a dose of 100 mg (free base equivalent dose) twice daily; and
(e) upon the patient having an ALT or AST of greater than 5 times ULN, permanently discontinuing treatment with the nirogacestat or pharmaceutically acceptable salt thereof, wherein the patient exhibits, at steady state exposure from administration of 150 mg (free base equivalent dose) of nirogacestat or a pharmaceutically acceptable salt thereof twice daily, a C max of nirogacestat of from about 300 to 700 ng/mL.

2. The method of claim 1 , wherein the method further comprises:
(f) for another severe adverse reaction or in the event of a life-threatening adverse reaction or persistent, intolerable Grade 2 adverse event, withholding the nirogacestat or pharmaceutically acceptable salt thereof until the adverse reaction is resolved to no higher than a Grade 1 adverse reaction or baseline and then, after considering the potential benefit and likelihood recurrence of the adverse reaction, (A) restarting oral administration of the nirogacestat or pharmaceutically acceptable salt thereof at a dose of 100 mg (free base equivalent dose) twice daily and (B) upon recurrence of the severe or life-threatening adverse reaction at the 100 mg (free base equivalent dose) twice daily dose, permanently discontinuing treatment with the nirogacestat or pharmaceutically acceptable salt thereof.

3. The method of claim 1 , wherein upon the patient having a Grade 3 dermatologic reaction, withholding the nirogacestat or pharmaceutically acceptable salt thereof until the dermatologic reaction is resolved to no higher than a Grade 1 dermatologic reaction and then restarting oral administration of the nirogacestat or pharmaceutically acceptable salt thereof at a dose of 100 mg (free base equivalent dose) twice daily.

4. The method of claim 1 , wherein the patient has a mutation in the adenomatous polyposis coli (APC) tumor suppressor gene.

5. The method of claim 1 , wherein the patient has a mutation in the CTNNB1 (β-catenin) gene.

6. The method of claim 1 , wherein the patient has intraabdominal tumors.

7. The method of claim 1 , wherein the patient has extraabdominal tumors.

8. The method of claim 1 , wherein the patient has a family history of familial adenomatous polyposis.

9. The method of claim 1 , wherein the patient has refractory or recurrent disease after previous treatment.

10. The method of claim 1 , wherein the patient is a treatment naïve patient.

11. The method of claim 1 , wherein the patient is a post-menopausal woman.

12. A method for therapeutic treatment of desmoid tumor in a patient in need thereof comprising orally administering to the patient 150 mg (free base equivalent dose) of nirogacestat or a pharmaceutically acceptable salt thereof twice daily, wherein the method further comprises:
(a) upon the patient having Grade 3 or 4 diarrhea persisting for at least 3 days despite medical therapy, withholding the nirogacestat or pharmaceutically acceptable salt thereof until the diarrhea is resolved to no higher than a Grade 1 diarrhea or baseline and then restarting oral administration of the nirogacestat or pharmaceutically acceptable salt thereof at a dose of 100 mg (free base equivalent dose) twice daily;
(b) upon the patient having Grade 3 or 4 hypophosphatemia persisting for at least 3 days despite replacement therapy, withholding the nirogacestat or pharmaceutically acceptable salt thereof until the hypophosphatemia is resolved to no higher than a Grade 1 hypophosphatemia or baseline and then restarting oral administration of the nirogacestat or pharmaceutically acceptable salt thereof at a dose of 100 mg (free base equivalent dose) twice daily;
(c) upon the patient having Grade 3 or 4 hypokalemia despite replacement therapy, withholding the nirogacestat or pharmaceutically acceptable salt thereof until the hypokalemia is resolved to no higher than a Grade 1 hypokalemia or baseline and then restarting oral administration of the nirogacestat or pharmaceutically acceptable salt thereof at a dose of 100 mg (free base equivalent dose) twice daily;
(d) upon the patient having an ALT or AST of 3 to 5 times ULN, withholding the nirogacestat or pharmaceutically acceptable salt thereof until the ALT, AST, or both are resolved to less than 3 times ULN or baseline and then restarting oral administration of the nirogacestat or pharmaceutically acceptable salt thereof at a dose of 100 mg (free base equivalent dose) twice daily; and
(e) upon the patient having an ALT or AST of greater than 5 times ULN, permanently discontinuing treatment with the nirogacestat or pharmaceutically acceptable salt thereof, wherein the nirogacestat or pharmaceutically acceptable salt thereof is nirogacestat dihydrobromide.

13. A method for therapeutic treatment of desmoid tumor in a patient in need thereof comprising orally administering to the patient 150 mg (free base equivalent dose) of nirogacestat or a pharmaceutically acceptable salt thereof twice daily, wherein the method further comprises:
(a) upon the patient having Grade 3 or 4 diarrhea persisting for at least 3 days despite medical therapy, withholding the nirogacestat or pharmaceutically acceptable salt thereof until the diarrhea is resolved to no higher than a Grade 1 diarrhea or baseline and then restarting oral administration of the nirogacestat or pharmaceutically acceptable salt thereof at a dose of 100 mg (free base equivalent dose) twice daily;
