A Study of the Pharmacokinetics and Safety of MK-8808 (MK-8808-002)
A Two-Part, Phase I Randomized, Double-Blind, Active-Comparator Controlled, Parallel Group Study to Assess the Pharmacokinetics, Safety, and Tolerability of MK-8808 and to Compare the Pharmacokinetics of MK-8808 With EU-approved MabThera® and US-licensed Rituxan® in Patients With Rheumatoid Arthritis (RA)

Detailed Description
In Part A of the base study, participants are randomized to either MK-8808 or MabThera®. In Part B of the base study, participants are randomized to either MK-8808, MabThera®, or Rituxan®. Participants enrolled in Part A are not eligible to participate in Part B. In both Parts A and B, participants will receive one or two courses of therapy, with each course including two infusions of the study drugs.
The extension portion of the study (Part C) will sequentially follow the base study beginning at Week 52 and continue for an additional 54 weeks. All participants who meet eligibility criteria and continue into the study extension will be treated with open-label MK-8808. Participants randomized to MK-8808 in the base study will remain on the same therapy. Participants randomized to rituximab (MabThera® or Rituxan®) in the base study will be switched to MK-8808 for the extension study.

American College of Rheumatology (ACR) Responder Index is based on a set of evaluations: the Investigator Tender Joint Count/Number of Tender Joints (out of 68 Joints); Investigator Swollen Joint Count/Number of Swollen Joints (out of 66 Joints); Patient Global Assessment of Disease Activity (PGAD); Investigator Global Assessment of Disease Activity (IGAD); Patient Global Assessment of Pain (PGAP); Health Assessment Questionnaire Disability Index (HAQ-DI); and ESR.
ACR response indicates percent change (ie, improvement) from baseline (20%, 50%, 70%) PGAD & IGAD: assessment of function on a 4-point Likert scale: 0=very well to 3=unable to do PGAP: pain due to arthritis measured on a 0-100 mm visual analog scale: Left hand marker-"no pain"; right hand marker-"extreme pain" HAQ-DI: assessment of 8 daily living activities (dress/groom; arise; eat; walk; reach; grip; hygiene; common daily activities) on 4-point Likert scale: 0=no difficulty to 3=unable to do

Change From Baseline in Disease Activity in 28 Joints C-Reactive Protein Score (DAS28-CRP) by Time-point
Time Frame: Baseline, Week 6, Week 12
|
The DAS28-CRP is a combination scoring method for function using the European League against Rheumatism (EULAR) 28 joint count and the CRP value.
The DAS28-CRP scores range from 2.0 to 10.0 with higher values indicating a higher disease activity.
A DAS28-CRP below the score of 2.6 is interpreted as Remission.
CRP values below lower limit of quantification (LLQ) (<0.4 mg/dL) were set to 0.2 mg/dL in the calculation of DAS28-CRP.
