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

Phase 1
Completed
Conditions
Rheumatoid Arthritis
Interventions
Registration Number
NCT03714022
Lead Sponsor
Bristol-Myers Squibb
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.

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.

Number of Participants Experiencing Positive Immunogenicity Response to AbataceptFrom Day 1 (Predose) to Day 71 (Study Discharge), assessed at day 1, day 29, day 57 and day 71

Positive immunogenicity response to Abatacept was defined if one of the following criteria was met:

1. missing baseline immunogenicity measurement and a positive, post-baseline, laboratory-reported immunogenicity response;

2. a negative laboratory-reported baseline immunogenicity response and a positive, post-baseline, laboratory-reported response;

3. a positive, laboratory-reported, baseline immunogenicity response and a positive, post-baseline, laboratory-reported immunogenicity response with a titer value greater than the baseline titer value.
