Brief summary

A Double-blind, Randomized, Placebo-controlled, Dose-escalation Phase I Study to Assess the Safety and PK/PD of LBL-047 Subcutaneous Injection in Healthy Adults and Patients with Systemic Lupus Erythematosus.

Detailed description

This study is a double-blind, randomized, placebo-controlled phase I clinical study to evaluate the safety, tolerability, PK, PD and immunogenicity of LBL-047 subcutaneously administered in healthy adults and subjects with systemic lupus erythematosus, while also preliminarily evaluating the clinical efficacy of LBL-047 in subjects with systemic lupus erythematosus. The study is divided into two parts. Part A: Study in healthy adults.A total of 7 dose-escalation cohorts were planned for Part A.Dose escalation will be determined by the Safety Monitoring Committee (SMC). Part B: Study in Adult Patients with Systemic Lupus Erythematosus.Part B will commence at a dose level that has been confirmed to be safe and tolerable in Part A. This study is projected to enroll 81 participants (potentially with an additional 36).

Inclusion criteria

1. Agree to follow the trial treatment regimen, visit schedule, laboratory test, and other requirements of the protocol, and voluntarily enroll in the study and sign the written informed consent. 2. Age 18-60 years (inclusive of boundaries) at the time of signing informed consent form. 3. Part A:Determined by the investigator to be in good health at the time of signing the ICF. 4. Part B:Mild to moderate systemic lupus erythematosus: SLEDAI-2K score ≥4 and ≤ 10 at screening. 5. Females of childbearing potential are willing to use highly effective contraception during the study and for 6 months after administration of the study drug and to avoid egg donation.Women of non-childbearing potential include: those with documented surgical sterilization or documented menopause. 6. Male of childbearing potential are willing to use highly effective contraception during the study and for 6 months after study drug administration and to avoid sperm donation.Men without fertility potential include those with: A semen sample investigation that confirms azoospermia, definitive evidence of infertility, or a history of vasoligation.For the purpose of this study, men with a "low sperm count" (or "subfertility") are not considered infertile.

Exclusion criteria

1. Part A:Symptoms or history of any significant disease, including but not limited to cardiovascular, hepatic, renal or any other disease that may interfere with the study results. 2. Part A:Abnormalities with clinical significance were indicated by vital signs, physical examination, laboratory test, 12-lead electrocardiogram (ECG), chest X-ray, and abdominal ultrasound. 3. Part B:History of organ transplant or hematopoietic stem cell/bone marrow transplant. 4. Part B:currently receiving treatment for any chronic infection (such as pneumocystosis, cytomegalovirus, herpes simplex virus, herpes zoster and atypical mycobacteriosis). 5. Major surgery (as judged by the investigator) within 90 days prior to dosing, or surgery scheduled during the study. 6. At screening, women of childbearing potential were positive for pregnancy.follicle stimulating hormone (FSH) did not reach postmenopausal level in postmenopausal women (defined as amenorrhoea ≥ 12 months before screening). 7. Large tattoo, scar or other condition that may interfere with assessment at the injection site. 8. unable to tolerate venipuncture, difficulty in blood collection or has a history of needle/blood phobic disorder. 9. The investigator determines that there are other conditions unsuitable for participation in this study.

Design outcomes

Primary

MeasureTime frameDescription
Occurrence of Treatment-Emergent adverse event (TEAE) and serious adverse event (SAE)From first dose until last visit(within 89 days after drug injection)Adverse event (AE) will be graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) 5.0.The safety profile of LBL-047 will be assessed by monitoring the adverse event (AE) and serious adverse event (SAE) During treatment.

Secondary

MeasureTime frameDescription
CmaxFrom first dose until last visit(within 89 days after drug injection)Maximum drug concentration in plasma after administration.
TmaxFrom first dose until last visit(within 89 days after drug injection)After administration,Time to reach maximum drug concentration in plasma.
ImmunogenicityFrom first dose until last visit(within 89 days after drug injection)The immunogenicity is evaluated by the incidence of anti-drug antibodies (ADA) and neutralizing antibodies (if applicable) in subjects.Immunogenicity refers to the performance that can elicit an immune response.
Assessment of PharmacodynamicsFrom first dose until last visit(within 89 days after drug injection)Drug therapy effect and adverse reaction, such as B cell level.
