A Study to Evaluate the Pharmacokinetics of Abatacept Converted From Drug Substance by Two Different Processes

Study Overview
=================
Brief Summary
-----------------
The main objective of this study is to compare the pharmacokinetics (PK) of the abatacept drug product converted from drug substance by a new drug substance process (Treatment A) relative to the current drug substance process (Treatment B) following a single dose (750 mg) intravenous (IV) infusion in healthy participants.

Detailed Description
-----------------
Participants will be admitted to the clinical facility the day prior to dosing (Day -1) and will be confined until at least 24 hours post-dose. On Day 1, eligible participants will be randomized in a 1:1 ratio to either Treatment A or Treatment B. The randomization will be stratified by weight categories: >= 60 to < 70 kg, >= 70 to < 80 kg, >= 80 to < 90 kg, and >= 90 to <= 100 kg.

Official Title
-----------------
A Randomized, Open-Label, Parallel-Group, Single-dose, Biocomparability Study of the Pharmacokinetics of the Abatacept (BMS-188667) Drug Product Converted From Drug Substance of a New Abatacept Drug Substance Process Relative to the Current Abatacept Drug Process in Healthy Participants

Conditions
-----------------
Rheumatoid Arthritis

Intervention / Treatment
-----------------
* Drug: Abatacept


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Body weight will be between 60 and 100 kg, inclusive. Women of childbearing potential (WOCBP) must have a negative serum pregnancy test within 24 hours prior to the start of study treatment. Women must not be breastfeeding. WOCBP must agree to follow instructions for method(s) of contraception for the duration of treatment with abatacept plus 5 half-lives of abatacept (85 days) plus 30 days (duration of ovulatory cycle) for a total of 115 days post-treatment completion. Males who are sexually active with WOCBP must agree to follow instructions for method(s) of contraception for the duration of treatment with abatacept plus 5 half-lives of abatacept (85 days) plus the duration of spermatogenesis (90 days) for a total of 175 days after the last dose of study treatment. In addition, male participants must be willing to refrain from sperm donation during this time. Exclusion Criteria: Participants who have a present malignancy or previous malignancy within the last 5 years prior to screening (except documented history of cured non-metastatic squamous or basal cell skin carcinoma or cervical carcinoma in situ). Participants who had a screening procedure that is suspicious for malignancy, and in whom the possibility of malignancy cannot be reasonably excluded following additional clinical, laboratory or other diagnostic evaluations. Participants with a history of herpes zoster. Donation of blood to a blood bank or in a clinical study (except a screening visit or follow-up visit) within 4 weeks of study treatment administration (within 2 weeks of study treatment administration for plasma only). Blood transfusion within 4 weeks of study treatment administration. Recent (within 6 months of study treatment administration) history of smoking or current smokers. This includes participants using electronic cigarettes or nicotine-containing products such as tobacco for chewing, nicotine patches, nicotine lozenges, or nicotine gum. History of allergy to abatacept or related compounds.
