| E.2.1 | Main objective of the trial |
This is the first study of MLN3897 in any disease population. It seeks to establish:
• The ability of MLN3897 to modify the signs and symptoms of
rheumatoid arthritis (RA)
• The safety and tolerability of MLN3897 in combination with
methotrexate (MTX)
• The pharmacokinetic (PK)/pharmacodynamic (PD) profile of
MLN3897 in the RA population, and comparison to that in the
healthy volunteer population with respect to CCR1 receptor
blockade
• MTX PK and MLN3897 PK and PD when these drugs are used in
combination |

| E.3 | Principal inclusion criteria |
Each patient must meet all of the following inclusion criteria to be enrolled into the study:
1. Be male or female aged 18 to 70 years (inclusive)
2. Meet the ACR diagnostic criteria for RA ( see section 16.1 for details). Patients with rheumatological disorders other than RA, where arthritis may be a prominent feature, such as systemic lupus erythematosus, mixed connective tissue disease, scleroderma, poly-dermatomytosis, Sjogren’s syndrome, etc, will be excluded. Patients with RA who have conditions associated secondarily with RA, such as osteoarthritis of affected joint(s) or sicca syndrome, may be enrolled.
3. Have an RA Global Functional Class of I, II, or III ( see section 16.2 for details).
4. Be taking MTX for a minimum of 6 months before screening with a stable, once weekly oral dose of 7.5 to 25 mg for at least 3 months prior to screening and plan to continue that regimen for the duration of the study
5. If taking oral corticosteroids, be taking no more than 10 mg/day of prednisone or its equivalent at a dose that has been unchanged for at least 4 weeks prior to screening
6. If taking NSAIDs, be taking a stable regimen of NSAIDs that has been unchanged for at least 2 weeks prior to screening
7. Be willing and able to comply with the protocol for the duration of the study
8. If female of childbearing potential (less than one year post-menopausal or not surgically sterile [tubal ligation does not qualify]), must not be pregnant or breast-feeding. Confirmation that a female patient is not pregnant must be established by a negative serum βhCG pregnancy test at screening and a negative urine pregnancy test on Day 1, prior to study drug administration.
9. Female patients of childbearing potential and all male patients must use two complementary methods of contraception while enrolled in the study
( eg,condom plus diaphragm,condom plus oral contraceptives,etc). All patients should use appropripriate contraceptives before and after the study as long as they continue taking background drug,MTX,in accordance with their physician's advice. Abstinence will be considered as an acceptable method of contraception on a case-by-case basis upon discussion with the Millennium or Covance medical monitor.
10. Have ≥6 swollen joints and ≥6 tender joints, plus at least 2 of the following:
• CRP >1.5 mg/dL (measured twice, at least 10 days apart, during screening)
• Morning stiffness with a duration of at least 45 minutes
• ESR ≥28 mm/h (measured twice, at least 10 days apart, during screening)
11. Provide written informed consent prior to any study-related procedures not conducted as part of normal medical care.

| E.5 End points |
| E.5.1 | Primary end point(s) |
The primary endpoint for efficay will be the percentage of patients achieving ACR20 at Day 84 in MLN3897 versus placebo-treated patients.
Study Endpoints:-
Efficacy: ACR response criteria assessment, DAS28-CRP assessment, time to
ACR20 response, HAQ-DI, European League Against Rheumatism (EULAR)
response criteria, and duration of morning stiffness will be evaluated.
Safety: AEs, vital signs, clinical laboratory assessments, physical examinations,
vision examinations, ECGs, peripheral blood leukocyte immunophenotyping
Pharmacokinetics: MTX, 7-hydroxy MTX, and MLN3897 PK parameters including
maximum plasma concentration (Cmax), time to reach maximum plasma concentration
(Tmax), and area under the plasma concentration-time curve from 0 to 24 hours
(AUC0-24) will be estimated from plasma concentration data using noncompartmental
methods. Additional PK parameters may be estimated and reported as appropriate. PK parameters for the 2 treatment groups will be compared statistically to assess whether concurrent use of MLN3897 has any effect on MTX and 7-hydroxy MTX PK, and also to determine whether MTX has any effect on the steady-state PK of MLN3897.
Pharmacodynamics: C-C chemokine receptor-1 (CCR1) internalization will be
assessed. |
