Compositions and methods for treating centrally mediated nausea and vomiting
Provided are compositions and methods for treating or preventing nausea and vomiting in patients undergoing chemotherapy, radiotherapy, or surgery.
1. A method of preventing acute and delayed nausea and vomiting in a subject receiving highly emetogenic cancer chemotherapy comprising inducing in said subject therapeutically effective blood levels of palonosetron and netupitant in a combination regimen with dexamethasone.
2. A method of achieving complete response during the acute and delayed phases of chemotherapy induced nausea and vomiting in a subject receiving highly emetogenic cancer chemotherapy comprising inducing in said subject therapeutically effective blood levels of palonosetron and netupitant in a combination regimen with dexamethasone.
3. A method of preventing nausea during the acute and delayed phases of chemotherapy induced nausea and vomiting in a subject receiving highly emetogenic cancer chemotherapy comprising inducing in said subject therapeutically effective blood levels of palonosetron and netupitant in a combination regimen with dexamethasone.
4. The method of claim 1 , wherein said blood levels are induced by an intravenous anti-emetic regimen administered prior to said chemotherapy.
5. The method of claim 1 , wherein (a) said blood levels are induced by an intravenous anti-emetic regimen administered prior to said chemotherapy, and (2) said blood levels are equivalent to blood levels induced by 50 to 500 mg of netupitant free base and 0.075 to 1.0 mg palonosetron hydrochloride administered orally.
6. The method of claim 1 , wherein (a) said blood levels are induced by an intravenous anti-emetic regimen administered prior to said chemotherapy, and (2) said blood levels are equivalent to blood levels induced by 300 mg of netupitant free base and 0.56 mg palonosetron hydrochloride administered orally.
7. The method of claim 1 , wherein said netupitant occupies at least 70% of said patient's striatum NK1 receptors seventy-two hours after said administration.
8. The method of claim 1 , wherein said method achieves complete response in said subject.
9. The method of claim 1 , wherein said method achieves no emesis in said subject.
10. The method of claim 1 , wherein said method achieves no rescue medication in said subject.
11. The method of claim 1 , wherein said method prevents nausea in said subject.
12. The method of claim 1 , wherein said blood levels of netupitant are independently effective to prevent acute and delayed nausea and vomiting in a subject receiving highly emetogenic cancer chemotherapy.
13. The method of claim 2 , wherein said blood levels are induced by an intravenous anti-emetic regimen administered prior to said chemotherapy.
14. The method of claim 2 , wherein (a) said blood levels are induced by an intravenous anti-emetic regimen administered prior to said chemotherapy, and (2) said blood levels are equivalent to blood levels induced by 50 to 500 mg of netupitant free base and 0.075 to 1.0 mg palonosetron hydrochloride administered orally.
15. The method of claim 2 , wherein (a) said blood levels are induced by an intravenous anti-emetic regimen administered prior to said chemotherapy, and (2) said blood levels are equivalent to blood levels induced by 300 mg of netupitant free base and 0.56 mg palonosetron hydrochloride administered orally.
16. The method of claim 2 , wherein said netupitant occupies at least 70% of said patient's striatum NK1 receptors seventy-two hours after said administration.
17. The method of claim 2 , wherein said method prevents nausea in said subject.
18. The method of claim 2 , wherein said blood levels of netupitant are independently effective to produce complete response in a subject receiving highly emetogenic cancer chemotherapy.
19. The method of claim 3 , wherein said blood levels are induced by an intravenous anti-emetic regimen administered prior to said chemotherapy.
20. The method of claim 3 , wherein (a) said blood levels are induced by an intravenous anti-emetic regimen administered prior to said chemotherapy, and (2) said blood levels are equivalent to blood levels induced by 50 to 500 mg of netupitant free base and 0.075 to 1.0 mg palonosetron hydrochloride administered orally.
21. The method of claim 3 , wherein (a) said blood levels are induced by an intravenous anti-emetic regimen administered prior to said chemotherapy, and (2) said blood levels are equivalent to blood levels induced by 300 mg of netupitant free base and 0.56 mg palonosetron hydrochloride administered orally.
22. The method of claim 3 , wherein said netupitant occupies at least 70% of said patient's striatum NK1 receptors seventy-two hours after said administration.
23. The method of claim 3 , wherein said blood levels of netupitant are independently effective to prevent nausea in a subject receiving highly emetogenic cancer chemotherapy.
