Summary

This is an open-label investigator-initiated trial (IIT) to assess the safety, efficacy, and PK（pharmacokinetic）/PD（pharmacodynamics ） of UB-VV410 in adult subjects with clinically active treatment-refractory SLE. The study population will include subjects with active LN (as defined by evidence of active inflammation on renal biopsy, referred to as the LN cohort) and subjects with active SLE without LN (ie, non-LN SLE, referred to as the non-LN cohort). It is expected that the safety profile of UB-VV410 will be similar in subjects with active LN and subjects with active non-LN SLE; thus, dose finding (DF) will be conducted in the 2 subpopulation cohorts combined. Dose expansion (DE) may be conducted separately in the LN and non-LN cohorts to characterize the preliminary efficacy of UB-VV410, as well as its safety and PK/PD, in each subpopulation.

The objective of this study is to determine the MTD（maximum tolerated dose）/MAD（maximum administered dose） and the recommended dose for subsequent studies of UB-VV410 in subjects with active LN and in subjects with active non-LN SLE. The DF portion will evaluate the safety profile of UB-VV410 administered at various DLs（dose levels）. The DE portion will further optimize the dose and define the safety profile and preliminary efficacy of UB VV410. The study will use the Bayesian optimal interval (BOIN) design to allocate subjects to various DLs to minimize exposure to subtherapeutic DLs while maintaining appropriate safety parameters. DF will be initiated with UB-VV410 administered IV and starting at DL1.

During DF, additional subjects may be backfilled at DLs found to be safe per the BOIN design and with promising activity. After DF of UB-VV410 has been completed, DE with up to 14 subjects per DL within each subpopulation cohort (eg, LN and non-LN cohorts) may be implemented at DLs less than or equal to the MTD/MAD and demonstrating efficacy to further characterize the toxicity, tolerability, PK/PD, and preliminary efficacy of UB-VV410 at the selected DLs. The DE portion will further characterize product safety and preliminary efficacy in order to optimize benefit/risk. The number of DLs for DE will be determined based on the safety, activity and PK/PD data observed from DF.

In addition, some subjects may receive retreatment with UB-VV410 if there are preliminary findings suggesting incomplete improvement and acceptable safety.
