Uses and compositions for treatment of juvenile rheumatoid arthritis
The invention provides methods, uses and compositions for the treatment of juvenile rheumatoid arthritis (JRA). The invention describes methods and uses for treating JRA, wherein a TNFα inhibitor, such as a human TNFα antibody, or antigen-binding portion thereof, is used to prevent flare-ups associated with JRA. Also described are methods for determining the efficacy of a TNFα inhibitor for treatment of JRA in a subject.
1 . A method of preventing a flare-up associated with juvenile rheumatoid arthritis (JRA) in a subject comprising administering a TNFα antibody, or antigen-binding portion thereof, to a subject, such that a flare up is prevented.
2 . A method for determining the efficacy of a TNFα antibody, or antigen-binding portion thereof, for the prevention of a flare-up associated with JRA in a subject, comprising
determining a median time to flare of a patient population having JRA and who was administered the TNFα antibody, or antigen-binding portion thereof,
wherein a median time to flare of at least about 14 weeks indicates that the TNFα antibody, or antigen-binding portion thereof, is an effective TNFα antibody, or antigen-binding portion thereof, for the prevention of flare associated with JRA.
3 . The method of claim 2 , further comprising administering the effective TNFα antibody, or antigen-binding portion thereof, to a subject to prevent a flare-up associated with JRA.
4 . A method of preventing a flare up in a subject having JRA comprising administering an effective TNFα antibody, or antigen-binding portion thereof, to a subject such that flare-up is prevented, wherein the effective TNFα antibody, or antigen-binding portion thereof, was previously identified as preventing a flare-up for at least about 14 weeks in a patient population having JRA.
5 . A method for determining the efficacy of a TNFα antibody, or antigen-binding portion thereof, for the prevention of a flare-up associated with JRA in a subject, comprising
determining a flare-up occurrence rate of a patient population having JRA and who was administered the TNFα antibody, or antigen-binding portion thereof,
wherein a flare-up occurrence rate of about 43% or less indicates that the TNFα antibody, or antigen-binding portion thereof, is an effective TNFα antibody, or antigen-binding portion thereof, for the prevention of the flare-up associated with JRA.
6 . The method of claim 5 , further comprising administering the effective TNFα antibody, or antigen-binding portion thereof, to a subject for the prevention of a flare-up associated with JRA.
7 . A method of preventing a flare up in a subject having JRA comprising administering an effective TNFα antibody, or antigen-binding portion thereof, to a subject such that the flare-up is prevented, wherein the effective TNFα antibody, or antigen-binding portion thereof, was previously identified as preventing a flare-up in about 43% or less of a patient population having JRA.
8 . A method for determining the efficacy of a TNFα inhibitor for the treatment of juvenile rheumatoid arthritis (JRA) in a subject comprising
determining a Pediatric (Ped) ACR90 response of a patient population having JRA and who was administered the TNFα inhibitor,
wherein a Ped ACR90 response achieved in at least about 15% of the patient population indicates that the TNFα inhibitor is an effective TNFα inhibitor for treating JRA.
9 . The method of claim 8 , further comprising administering the effective TNFα inhibitor to a subject to treat JRA.
10 . The method of claim 9 , wherein the TNFα inhibitor is administered either with or without methotrexate.
11 . A method for treating JRA in a subject comprising administering an effective TNFα inhibitor to the subject such that JRA is treated, wherein the effective TNFα inhibitor was previously identified as achieving a PedACR90 response in at least about 15% of a patient population having JRA.
12 . The method of claim 11 , further comprising administering methotrexate to the subject.
13 . The method of claim 8 - 12 , wherein the TNFα inhibitor is selected from the group consisting of a TNFα antibody, or an antigen-binding portion thereof, a TNFα fusion protein, or a recombinant TNFα binding protein.
14 . A method for treating JRA in a subject comprising subcutaneously administering a human TNFα antibody, or antigen-binding portion thereof, at a dose of 24 mg/M 2 BSA to the subject on a biweekly dosing regimen.
15 . The method of claim 14 , wherein the human TNFα antibody, or antigen-binding portion thereof, is adalimumab.
16 . An article of manufacture comprising
a) a packaging material;
b) a TNFα antibody, or antigen-binding portion thereof; and
c) a label or package insert indicating that in studies of the TNFα antibody, or antigen-binding portion thereof, for the treatment of juvenile rheumatoid arthritis (JRA) the most common adverse events (AEs) were infections.
17 . An article of manufacture comprising
a) a packaging material;
b) a TNFα antibody, or antigen-binding portion thereof; and
c) a label or package insert indicating that in studies of the TNFα antibody, or antigen-binding portion thereof, the TNFα antibody was shown to prevent flare-ups in patients having JRA.
