Low frequency glatiramer acetate therapy
A method of alleviating a symptom of relapsing-remitting multiple sclerosis in a human patient suffering from relapsing-remitting multiple sclerosis or a patient who has experienced a first clinical episode and is determined to be at high risk of developing clinically definite multiple sclerosis comprising administering to the human patient three subcutaneous injections of a therapeutically effective dose of glatiramer acetate over a period of seven days with at least one day between every subcutaneous injection so as to thereby alleviate the symptom of the patient.
1. A method of treatment of a human patient suffering from a relapsing form of multiple sclerosis which consists of a regimen of administering weekly to the human patient on only three days during each week a single subcutaneous injection of a 40 mg dose of glatiramer acetate so as to treat the human patient, wherein the glatiramer acetate is present in 1 ml of a pharmaceutical composition in a prefilled syringe for self administration by the human patient, and the pharmaceutical composition further comprises mannitol and has a pH in the range of 5.5 to 7.0.
2. The method of claim 1 , wherein the three days during each week are selected from the group consisting of day 1, day 3 and day 5; day 1, day 3 and day 6; day 1, day 4 and day 6; day 2, day 4 and day 6; day 2, day 4 and day 7; day 2, day 5 and day 7; and day 3, day 5 and day 7.
3. The method of claim 1 , wherein the treatment results in reducing the frequency of relapses in the human patient by 30% or more as compared to placebo in a human population.
4. The method of claim 3 , wherein the treatment further results in i) reducing the cumulative number of enhancing lesions on T 1 -weighted images of the human patient, and ii) reducing brain atrophy of the human patient.
5. The method of claim 1 , wherein the human patient has not received glatiramer acetate therapy prior to initiation of the treatment.
6. The method of claim 5 , wherein the three days during each week are selected from the group consisting of day 1, day 3 and day 5; day 1, day 3 and day 6; day 1, day 4 and day 6; day 2, day 4 and day 6; day 2, day 4 and day 7; day 2, day 5 and day 7; and day 3, day 5 and day 7.
7. The method of claim 5 , wherein the treatment results in reducing the frequency of relapses in the human patient by 30% or more as compared to placebo in a human population.
8. The method of claim 7 , wherein the treatment further results in i) reducing the cumulative number of enhancing lesions on T 1 -weighted images of the human patient, and ii) reducing brain atrophy of the human patient.
9. A method of treatment of a human patient suffering from a relapsing form of multiple sclerosis consisting of subcutaneous injections for at least 6 months of 1 ml of a pharmaceutical composition comprising 40 mg/ml of glatiramer acetate on only three days during each week with at least one day without a subcutaneous injection of the pharmaceutical composition between each day on which there is a subcutaneous injection, wherein the pharmaceutical composition is in a prefilled syringe, and wherein the pharmaceutical composition further comprises mannitol and has a pH in the range 5.5 to 7.0.
10. The method of claim 9 , wherein during each week the subcutaneous injections are on day 1, day 3 and day 5 of such week; day 1, day 3 and day 6 of such week; day 1, day 4 and day 6 of such week; day 2, day 4 and day 6 of such week; day 2, day 4 and day 7 of such week; day 2, day 5 and day 7 of such week; or day 3, day 5 and day 7 of such week.
11. The method of claim 9 , wherein the treatment results in reducing the frequency of relapses in the human patient by 30% or more as compared to placebo in a human population.
12. The method of claim 11 , wherein the treatment further results in i) reducing the cumulative number of enhancing lesions on T 1 -weighted images of the human patient, and ii) reducing brain atrophy of the human patient.
13. The method of claim 9 , wherein the human patient has not received glatiramer acetate therapy prior to initiation of the treatment.
14. The method of claim 13 , wherein the treatment results in reducing the frequency of relapses in the human patient by 30% or more as compared to placebo in a human population.
15. The method of claim 14 , wherein the treatment further results in i) reducing the cumulative number of enhancing lesions on T 1 -weighted images of the human patient, and ii) reducing brain atrophy of the human patient.
16. A method of treatment of a human patient suffering from a relapsing form of multiple sclerosis which method is more tolerable than and as effective as administration of 20 mg of glatiramer acetate s.c. daily, the method consisting of subcutaneous injections for at least 6 months of 1 ml of a pharmaceutical composition comprising 40 mg/ml of glatiramer acetate on only three days during each week with at least one day without a subcutaneous injection of the pharmaceutical composition between each day on which there is a subcutaneous injection, wherein the pharmaceutical composition is in a prefilled syringe, and wherein the pharmaceutical composition further comprises mannitol and has a pH in the range 5.5 to 7.0, so as to treat the human patient as effectively as, but more tolerably than, administration of 20 mg of glatiramer acetate s.c. daily, wherein the effect is reduction of relapses.
17. The method of claim 4 , wherein the treatment further results in reducing a change in EDSS Score of the human patient.
18. The method of claim 8 , wherein the treatment further results in reducing a change in EDSS Score of the human patient.
19. The method of claim 12 , wherein the treatment further results in reducing a change in EDSS Score of the human patient.
20. The method of claim 15 , wherein the treatment further results in reducing a change in EDSS Score of the human patient.
21. The method of claim 1 , wherein the treatment results in reduced severity of injection site reactions relative to administration of 20 mg of glatiramer acetate s.c. daily.
22. The method of claim 9 , wherein the treatment results in reduced severity of injection site reactions relative to administration of 20 mg of glatiramer acetate s.c. daily.
23. The method of claim 11 , wherein the treatment results in reduced severity of injection site reactions relative to administration of 20 mg of glatiramer acetate s.c. daily.
24. The method of claim 1 , wherein the treatment results in reduced frequency and severity of both immediate post injection reactions and injection site reactions, relative to administration of 20 mg of glatiramer acetate s.c. daily.
25. The method of claim 9 , wherein the treatment results in reduced frequency and severity of both immediate post injection reactions and injection site reactions, relative to administration of 20 mg of glatiramer acetate s.c. daily.
26. The method of claim 11 , wherein the treatment results in reduced frequency and severity of both immediate post injection reactions and injection site reactions, relative to administration of 20 mg of glatiramer acetate s.c. daily.
27. The method of claim 12 , wherein the treatment results in reduced frequency and severity of both immediate post injection reactions and injection site reactions, relative to administration of 20 mg of glatiramer acetate s.c. daily.
28. The method of claim 13 , wherein the treatment results in reduced frequency and severity of both immediate post injection reactions and injection site reactions, relative to administration of 20 mg of glatiramer acetate s.c. daily.
