Abstract

A perfusion container for directly administering to patients a dose of an antineoplastic drug calculated according to a patient's parameter, wherein the first perfusion container comprises a solution of antineoplastic drug at a concentration and volume such that the amount of antineoplastic drug in the container is equal to the calculated dose for one patient but less than the calculated dose for a second patient, the calculated dose is provided to first patient within 5% variance by directly administering the full volume of the solution of antineoplastic drug from the first perfusion container, further the first perfusion container is accompanied by a second top-up perfusion container comprising a solution of antineoplastic drug at a concentration and volume such that the calculated dose is provided within 5% variance by directly administering the full volume of the solution of antineoplastic drug from the first perfusion container and the second top-up container to the second patient.

First claim

The invention claimed is:

1. A method for directly administering a dose of an antineoplastic drug to a patient in a patient population in need thereof, the dose calculated according to a patient parameter, wherein the parameter varies over a range in the patient population, the method comprising the steps of:
providing a perfusion system comprising:
a plurality of perfusion containers, each perfusion container consisting essentially of a ready-to-infuse, aqueous perfusion solution of the antineoplastic drug contained within the perfusion container and one outlet for withdrawal of the aqueous perfusion solution from the perfusion container during direct administration to a patient, wherein said plurality of perfusion containers comprise (a) a first set of perfusion containers consisting essentially of a first ready-to-infuse, aqueous perfusion solution of the antineoplastic drug at a first antineoplastic drug concentration, (b) a second set of top-up perfusion containers consisting essentially of a second ready-to-infuse, aqueous perfusion solution of the antineoplastic drug at a second antineoplastic drug concentration, and optionally (c) a third set of top-up perfusion containers consisting essentially of a third ready-to-infuse, aqueous perfusion solution of the antineoplastic drug at a third antineoplastic drug concentration;

calculating the dose according to the patient parameter;
selecting one or more perfusion container(s) from the first set of perfusion container(s) and if necessary from the second and/or third set of top-up perfusion container(s) required for directly administering a dose equal to or less than ±5% of the calculated dose; and
directly administering to the patient in need, thereof the perfusion solution in the selected containers without any manipulation of the aqueous perfusion solution prior to said administration, wherein
the method is to be performed on any patient in the patient population regardless of the calculated dose.

2. The method of claim 1 , wherein the perfusion system further comprises:
a third set of top-up perfusion containers, each top-up perfusion container of the third set consisting essentially of the ready-to-infuse, aqueous perfusion solution of the antineoplastic drug at a third concentration contained within the top-up perfusion container and one outlet for withdrawal of the aqueous perfusion solution from the top-up perfusion container during direct administration to a patient.

3. The method as claimed in claim 2 , wherein
at least one of the first set of perfusion containers, the second set of top-up perfusion containers, and the third set of top-up perfusion containers comprises a plurality of containers containing different volumes of ready-to-infuse, aqueous perfusion solutions of the antineoplastic drug.

4. The method as claimed in claim 2 , wherein at least two of the first antineoplastic drug concentration, the second antineoplastic drug concentration and the third antineoplastic drug concentration are the same.

5. The method as claimed in claim 2 , wherein volumes of solution in the individual containers is the same or different.

6. The method as claimed in any of claims 2 to 5 , wherein the patient parameter is selected from body surface area, body-weight, renal function or hepatic function.

7. The method as claimed in claim 2 , wherein at least two of the first antineoplastic drug concentration, the second antineoplastic drug concentration, and the third antineoplastic drug concentration are different.

8. The method as claimed in claim 2 , wherein the first antineoplastic drug concentration is higher than the second antineoplastic drug concentration and the second antineoplastic drug concentration is higher than the third antineoplastic drug concentration.

9. The method as claimed in claim 2 , wherein
each of the perfusion containers in the first set of perfusion containers consists essentially of a first volume of the aqueous perfusion solution of the antineoplastic drug;
each of the perfusion containers in the second set of perfusion containers consists essentially of a second volume of the aqueous perfusion solution of the antineoplastic drug; and
each of the perfusion containers in the third set of perfusion containers consists essentially of a third volume of the aqueous perfusion solution of the antineoplastic drug.

10. The method as claimed in claim 9 , wherein the first concentration is higher than the second concentration and the second concentration is higher than the third concentration.

11. The method of claim 9 , wherein the first volume, the second volume, and the third volume are different.

12. The method of claim 9 , wherein at least two of the first volume, the second volume, and the third volume are different.

13. The method as claimed in claim 1 , wherein the first antineoplastic drug concentration and the second antineoplastic drug concentration are the same.

14. The method as claimed in claim 1 , wherein
each of the perfusion containers in the first set of perfusion containers consists essentially of a first volume of the aqueous perfusion solution of the antineoplastic drug; and
each of the perfusion containers in the second set of perfusion containers consists essentially of a second volume of the aqueous perfusion solution of the antineoplastic drug;
wherein the first volume and the second volume are different.

15. The method as claimed in any one of claims 1 , 13 , 12 , and 14 , wherein the patient parameter is selected from body surface area, body-weight, renal function or hepatic function.

16. The method as claimed in claim 1 , wherein the first antineoplastic drug concentration and the second antineoplastic drug concentration are different.

17. The method as claimed in claim 16 , wherein the first antineoplastic drug concentration is higher than the second antineoplastic drug concentration.

18. The method according to claim 1 wherein the number of containers per the first set and/or the second set is 1 or 2.

19. The method according to claim 18 wherein the number of containers per the first set and/or the second set is 1.

20. The method of claim 1 , wherein the antineoplastic drug is selected from carboplatin, oxaliplatin, vincristine, vinblastine, vinorelbine, vindesine, pemetrexed, gemcitabine, irinotecan, topotecan, methotrexate, docetaxel, paclitaxel, doxorubicin, daunonibicin, epirubicin, idarubicin, streptozocin, mitomycin, gentamicin, tenoposide, 5-fluorouracil, ifosfamide, cyclophosphamide, mechlorethamine, carmustine, dacarbazine, cladribine, clofarabine, fulvestrant, pegfilgrastim, pamidronate, zoledronic acid, mitoxantrone, leukovorin, etoposide, triplatin, picoplatin, satraplatin, lobaplatin, and pharmaceutically acceptable salts thereof.

21. A method for treating cancer or a neoplastic disorder in a patient in a patient population in need thereof, the dose calculated according to a patient parameter, wherein the parameter varies over a range in the patient population, the method comprising the steps of:
providing a perfusion system comprising:
a plurality of perfusion containers, each perfusion container consisting essentially of a ready-to-infuse, aqueous perfusion solution of the antineoplastic drug contained within the perfusion container and one outlet for withdrawal of the aqueous perfusion solution from the perfusion container during direct administration to a patient, wherein said plurality of perfusion containers comprise (a) a first set of perfusion containers consisting es
