About this study

Official title: A Randomized, Double-blind, Placebo-controlled Phase I/II Study to Evaluate the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Efficacy of SCTC21C in Subjects With Plasma Cell-driven Autoimmune Diseases

The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and efficacy of SCTC21C in subjects with plasma cell-driven autoimmune diseases

Read the detailed description

This is a randomized, double-blind, placebo-controlled Phase I/II study to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and efficacy of multiple doses of SCTC21C in subjects with plasma cell-driven autoimmune diseases.

In phase 1 study, participants will be assigned to receive sequentially higher doses of SCTC21C to determine the recommended dose of SCTC21C for the randomized dose optimization- stage. In phase 2 study, 2 dose levels will be used. A total of 72 participants will be randomized in a 1:1:1 ration to dose 1, dose 2 or placebo groups to better understand the exposure/efficacy/toxicity relationship.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Phase 1: Treatment-emergent adverse events (TEAEs), serious adverse events (SAEs).

    An adverse event (AE) is any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.

    A serious adverse event (SAE) is any untoward medical occurrence that at any dose:

    Results in death Is life-threatening Requires in patient hospitalisation or prolongation of existing hospitalisation Is a congenital anomaly or birth defect Is an infection that requires treatment parenteral antibiotics Other important medical events which based on medical or scientific judgement may jeopardise the patients, or may require medical or surgical intervention to prevent any of the above.

    Measured: 36 Weeks

  2. Phase 2: Percentage change in urine protein-to-creatinine ratio (UPCR) at Week 24 compared to baseline

    UPCR is calculated by dividing the concentration of protein in urine by the urine creatinine concentration.

    Measured: 24 Weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing SCTC21C in people with IgA Nephropathy, run by Sinocelltech Ltd. at 20 sites in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 14 Jan 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 20 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Qiang Zhou (+86-10-58628288, qiang_zhou@sinocelltech.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Phase 1: Treatment-emergent adverse events (TEAEs), serious adverse events (SAEs). (time frame: 36 Weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Jan 2025.
