35The purpose of this first in human study is to evaluate the safety and tolerability of RPH-104 in humans.
RPH-104 is a macromolecular compound with a molecular weight of 152.715 kilodalton (Data on file) and is capable of binding human interleukin-1 beta (IL-1β). It has also been shown in vitro to be a highly potent inhibitor of IL-1β signalling pathway, with low picomolar inhibitor activity. In this First in Human study, RPH-104 will be evaluated primarily for its safety and tolerability. In a phase I study conducted with health volunteers, a similar monoclonal antibody, canakinumab, was investigated in terms of pharmacokinetics and pharmacodynamics besides efficacy and safety. Similarly, this aimed to investigate effects of RPH-104 on selected pharmacodynamic parameters, including Anti-Drug Antibodies (ADA) along with obtaining first human data on pharmacokinetics of RPH-104 in humans will be investigated in the same study.
Anti-IL-1 Mab
Sterile saline solution
A single dose of RPH-104 (4, 20, 40, 80 or 160 mg) will be administered subcutaneously.
A single 0.9% sodium chloride injection will be administered subcutaneously.

Number of participants with study drug related adverse events
Number of Participants with Study Drug Related Serious Adverse Events
Percentage of participants with abnormal respiratory rate. The normal respiration rate for an adult at rest is 12 to 20 breaths per minute.
Percentage of participants with abnormal blood pressure. An optimal blood pressure level is a reading under 120/80 mmHg
Percentage of participants with abnormal oxygen saturation. Normal pulse oximeter readings usually range from 95 to 100 percent. Values under 90 percent are considered low.
Percentage of participants with abnormal body temperature. Among adults, the average body temperature ranges from 97°F (36.1°C) to 99°F (37.2°C).
Percentage of participants with abnormal clinical laboratory tests. Normal laboratory ranges of the central laboratory were used.
Mean AUC 0-t (area under the concentration- time curve from time zero to day 30)
Median Tmax. Definition of Tmax is time at which Cmax occurs.
Mean t½. Definition of t½ is terminal elimination half-life.
Mean Cmax. Highest concentration determined in the measuring interval.
