E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
• To characterize the PK/PD relationship between systemic CDP6038 exposure and CRP suppression, following single dose CDP6038 administration via iv infusion and sc injection to subjects with RA. • To evaluate the safety and tolerability of single doses of CDP6038 in RA subjects over a therapeutic dose range (as defined by CRP suppression). |
|
E.2.2 | Secondary objectives of the trial |
• To determine the absolute bioavailability of CDP6038 given via sc administration in comparison with iv infusion in subjects with RA. • To assess the immunogenicity of single dose CDP6038 in subjects with RA. • To assess, on an exploratory basis, changes in clinical response and other systemic biomarkers with CDP6038 dosing. |

Subject has an ECG with interpretations considered as “normal” or as “abnormal” but within the agreed upon clinically nonsignificant ranges predefined by the Sponsor in the ECG manual. 10. Subject has results of clinical safety laboratory tests, including liver function tests, within the laboratory reference ranges or outside the laboratory reference range but within limits predefined by the Sponsor in the laboratory manual and deemed acceptable and not clinically relevant by the Investigator. 11. The subject is considered to be reliable and capable of adhering to the protocol, according to the judgment of the Investigator. |

Subject with a positive TIGRA (T-cell interferon-γ release assay) and/or positive skin test (purified protein derivative [PPD] or positive TIGRA only, in case of contraindication to PPD skin testing, for tuberculosis and/or a chest x–ray showing evidence of possible latent/active tuberculosis. 14. Subject with evidence from chest x-ray of interstitial lung disease. Subjects with other abnormalities on chest x-ray which, in the opinion of the Investigator would prevent appropriate evaluation of the subject. 15. Subject with a positive test to Human Immunodeficiency Virus-1/2 antibody (HIV 1/2Ab). 16. Subject has known viral hepatitis, has a positive test for Hepatitis B surface antigen or is Hepatitis C virus antibody positive. 17. Subject with a history of chronic alcohol abuse within the last 2 years, or a positive alcohol test at Screening and/or Day-1. Subjects should restrict their alcohol consumption to no more than 1 unit per week. 18. Subject with a history of drug addiction within the last 2 years or current drug addiction or use. 19. Subject with uncontrolled hypertension - systolic blood pressure (SBP) >150mmHg or diastolic blood pressure (DBP) >95mmHg. 20. Subject with orthostatic hypotension, defined as per protocol. Blood pressure should be taken as per protocol. 21. Subject has any psychological or other emotional problems that are likely to invalidate informed consent, or limit the ability of the subject to comply with the protocol requirements. 22. Subjects with any other condition which in the Investigator’s judgment would make the subject unsuitable for inclusion in the study. 23. Vulnerable and legally detained individuals. 24. Employees of the Investigator or study center, with direct involvement in the proposed study or other studies under the direction of that Investigator or study center, as well as family members of the employees or the Investigator. 25.
