Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of treatment-emergent adverse events (TEAEs) | Up to 3 months | Incidence, nature, and severity of treatment-emergent adverse events, assessed according to the study protocol and applicable toxicity grading criteria. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Quantify the clinical activity of HN2301 in patients using Physician Global Assessment (PGA) . | Day-28 to12 months | Assessment of Physician Global Assessment (PGA) from baseline administration at various timepoints up to month 12 follow up visit. A total score can fall between 0.0 and 3.0, with a higher score representing a more significant degree of disease activity. |
| Proportion of participants achieving lupus low disease activity status (LLDAS) | Day-28 to12 months | Proportion of participants who achieve LLDAS at scheduled visits through Month 12. |
| Proportion of patients achieving DORIS remission after HN2301 administration | Day-28 to12 months | Assessment of DORIS response rate at various timepoints up to the month 12 follow-up visit. |
| Assess the clinical activity of HN2301 in patients with SLE using Systemic Lupus Erythematosus Responder Index-4 (SRI-4) | Day-28 to12 months | Assessment of whether participants meet the Systemic Lupus Erythematosus Responder Index-4 (SRI-4) criteria (yes/no) at various timepoints up to the month 12 follow-up visit. |
| Proportion of patients achieving complete renal response (CRR) after HN2301 administration | Day-28 to12 months | Proportion of patients achieving complete renal response (CRR) after HN2301 administration |
| Changes from baseline in Patient Global Assessment(PtGA) scores | Up to 12 months | Assessment of change from baseline in Patient Global Assessment (PtGA) of overall disease activity at scheduled visits through Month 12,typically on a 0 to 10 numeric scale, where 0 indicates no disease activity and 10 represents the worst possible activity. |
| Change from baseline in modified Rodnan Skin Score (mRSS) | Up to 12 months | Assessment of change from baseline in modified Rodnan Skin Score (mRSS). Total scores range from 0 to 51, with higher scores indicating greater skin thickening. |
| Changes from baseline in Health Assessment Questionnaire Disability Index (HAQ-DI) score | Up to 12 months | Assessment of change from baseline in Health Assessment Questionnaire Disability Index (HAQ-DI), a patient-reported measure of functional ability across 8 domains, the patient responds on a scale of 0 (no disability) to 3 (completely disabled). |
| Change from baseline in revised Composite Response Index in Systemic Sclerosis (r-CRISS) score | Up to 12 months | Assessment of change from baseline in the revised Composite Response Index in Systemic Sclerosis (r-CRISS), a weighted composite score based on 5 core measures of disease status, improved by a certain percentage in ≥3 of 5 core set measures. |
| Changes from baseline in Disease Activity Score (DAS28) score | Up to 12 months | Proportion of patients disease activity changes, a scale from 0 to 10 indicating the current activity of the rheumatoid arthritis. A DAS28 above 5.1 means high disease activity whereas a DAS28 below 3.2 indicates low disease activity. |
| Changes from baseline in Visual Analogue Scale (VAS) score | Up to 12 months | A total score can fall between 0 and 10 |
| vivo CAR T cell production | Day-28 to14 days | CAR T production in the peripheral blood of AID patients, by flow cytometry (FACS), and quantitative polymerase chain reaction (qPCR) in peripheral blood |
| Change from baseline of SLEDAI-2K score after HN2301 administration. | Day-28 to12 months | Assessment of Systemic Lupus Erythematosus Disease Activity Index 2000 from baseline administration at various timepoints up to month 12 follow-up visit. A total score can fall between 0 and 105, with a higher score representing a more significant degree of disease activity. |
| B cell ratio and counts in peripheral blood | Day-28 to12 months | Assessment of B cell ratio and counts (B cell counts per μl peripheral blood) and B cell subsets(naive B cell, memory B cell) by flow cytometry (FACS) in peripheral blood |
