Brief Summary

A multi-center, multi-dose phase Ib/IIa clinical study evaluating the safety, tolerability, preliminary efficacy, pharmacokinetics, and impact on biomarkers of IPG11406 in patients with Lupus Nephritis

Detailed Description

This is a multi-center, multi-dose phase Ib/IIa study to evaluate the safety, tolerability, preliminary efficacy, pharmacokinetics, and impact on biomarkers of IPG11406 in patients with Lupus Nephritis.

Part A Three dose groups will be administered with drugs, namely 20 mg bid (cohort 1), 40 mg bid (cohort 2), and 80 mg bid (cohort 3). In cohorts 1 to 3, there will be 9-12 subjects in each cohort. All subjects will undergo screening for 28 days before administration, and those who pass the screening will undergo 28 days of drug administration and observation. This part plans to recruit about 36 patients with Lupus Nephritis.

After each cohort completes 28 days of dosing and evaluation, the Safety Monitoring Committee (SMC) will assess the safety and tolerability of IPG11406 based on all accumulated safety data (including follow-up data) and available pharmacokinetic (PK) data under blinded conditions. Based on the results of the safety and tolerability assessment, the SMC will decide whether to proceed with dosing in the next dose cohort. Part A will determine the recommended phase II dose (RP2D) and maximum tolerated dose (MTD) of IPG11406.

Part B The design of Part B will be finalized based on the results of Part A.

Minimum and Maximum Values:

The SLEDAI-2K score ranges from 0 (indicating no disease activity) to a maximum possible score that depends on the specific items being scored. However, in practical clinical use, the maximum score is typically much lower than the theoretical maximum, as not all items will be positive in any given patient. The exact maximum score can vary slightly depending on the specific version of the SLEDAI-2K being used, but it is generally well below 100.

In the SLEDAI-2K, higher scores indicate a worse outcome. This is because the scale assigns points based on the presence and severity of various lupus manifestations, such as arthritis, rash, fever, and organ involvement. Therefore, as the score increases, it reflects greater disease activity and potentially more severe disease manifestations.
