About this study

This is a first in human, open-label, dose escalation and expansion Phase 1 study of SIM1811-03 in adult patients with advanced solid tumors and cutaneous T-cell lymphoma. SIM1811-03 is a first-in-class IgG1-based humanized anti-tumor necrosis factor type 2 receptor (TNFR2) monoclonal antibody for the treatment of malignant tumors.

Read the detailed description

This is a phase I trial to evaluate the safety, efficacy, and pharmacokinetic/ pharmacodynamic characteristics of SIM1811-03 in subjects with advanced solid tumors and subjects with CTCL.

The trial is composed of two parts, phase Ia and phase Ib. Phase Ia is a dose escalation part to determine the MTD and/or RD of SIM1811-03. Phase Ib is a dose expansion part at RD level SIM1811-03 determined in phase Ia to primarily assess the anti-tumor activity of SIM1811-03 in subjects with solid tumors or CTCL. The tumor types in PhIb will be adjusted based on the response observed in PhIa. Approximately 50 subjects will be enrolled in this phase.

Cohort 1: Patients with CTCL (approximately 20 patients). Cohort 2: Patients with advanced/metastatic solid tumors, including ovarian cancer (approximately 10 patients), NSCLC (approximately 10 patients), and hepatocellular carcinoma etc.

Each subject will undergo Screening, Treatment, Safety Follow-up, and survival Follow-up periods. Any subject who has discontinued from study treatment other than disease progression will also enter PFS follow up period and to continue to have tumor assessments until disease progression, initiation of subsequent anticancer therapies, or death, whichever occurs first. Upon completion of the safety follow up and PFS follow-up, as applicable, all patients, except those who died, withdrew consent or were lost to follow-up, will be followed for survival.

Eligible subjects will receive intravenous infusion of SIM1811-03 on Days 1 and 15 of each 28-day cycle.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing SIM1811-03 in people with Advanced Solid Tumor and Cutaneous T-cell Lymphoma (CTCL), run by Jiangsu Simcere Pharmaceutical Co., Ltd. at 6 sites in United States.

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 16 inclusion and 16 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: status not confirmed, as of the sponsor's last update on 7 Oct 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in United States. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this 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.

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

Are results available for this study?

Results are not available in the source record.

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

Contact Bijoyesh Mookerjee, M.D. (856-261-0153, bijoyesh.mookerjee@simceregroup.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Phase 1a: Incidence Rate of Dose-Limiting Toxicity (DLT) (time frame: Within 28 days after the first dose). 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 7 Oct 2022.
