NEX-20A will be administered in sequential cohorts, 2 standard cohorts and an optional third cohort, each comprising 3 subjects. Subjects will be dosed in a sentinel fashion, and all available safety and tolerability data up until and including 10 days for the sentinel subjects must have been evaluated by the iSRC before dosing the remaining 2 subjects in each cohort.Once safety, tolerability and PK data of the last subject in each cohort has been collected, and interim data analysis has been conducted, there must be at least 1 week between dose escalations.
This is a single-centre, single ascending dose (SAD) pilot study designed to evaluate the safety, tolerability, including local tolerability, and pharmacokinetics (PK) of NEX-20A (lenalidomide) after the administration of a single subcutaneous prolonged-release injection to healthy male volunteers
