Phase I, Pharmacokinetic, Safety and Tolerability Study in Healthy Volunteers

• Status: Completed
• Trial end date: 2018-12-20
• Target enrollment: 0
• Participant gender: All

Summary

This is a randomized, double-blind, 3-arm, parallel-group single-dose study to compare the PK, PD, safety, tolerability, and immunogenicity of LusiNEX (Mycenax tocilizumab) versus RoActemra (EU tocilizumab) and Actemra (US tocilizumab) after a single IV infusion of 4 mg/kg in healthy volunteers (hereafter referred to as subjects). The therapeutic dose of tocilizumab starts with 4 mg/kg and ranges to 12 mg/kg, considering 4 mg/kg is the lowest dose, the same has been selected for the study.

9. Non-smokers or social smokers (defined as less than 10 cigarettes per week). No current use of any nicotine containing product. Cotinine levels ≤5 ng/mL.

10. Willing to abstain from sexual intercourse or use 2 methods of contraception (both male and female partners) as defined in the protocol for 3 months after study drug administration.

Female subjects who are using oral hormonal contraceptives must be willing to use, with their partner, 2 methods of contraception as defined as defined in the protocol.

12. Use of any prescription or over-the-counter medication (with the exception of contraceptive medication in females and paracetamol) within 7 days of Screening and for the duration of participation in the study.
