About this study

Official title: Phase 1b Proof-of-concept, Open-label Study to Assess the Safety and Pilot Efficacy of Enbrel® Administered by the Sofusa® DoseConnect™ Delivery System for the Treatment of Rheumatoid Arthritis

This is an open-label pilot study in patients with rheumatoid arthritis (RA). All patients will receive SOFUSA Enbrel 25 mg once weekly. The dose will be increased to 50 mg if the dose escalation criteria are met during the dose escalation phase of the study.

Read the detailed description

This study is a Phase 1b proof-of-concept, open-label study to assess the safety and pilot efficacy of Enbrel administered by the Sofusa® DoseConnect™ delivery system (SOFUSA) for the treatment of patients with moderately to severe RA and an inadequate response to subcutaneous (SC) Enbrel. SOFUSA Enbrel will be administered once weekly to patients for 12 weeks. Patients will start on an Enbrel dose of 25 mg during the induction phase of the study and may be increased to an Enbrel dose of 50 mg during the dose escalation phase of the study based on the dose escalation criteria. Patients will remain on either the 25 mg or 50 mg dose for the final maintenance phase of the study.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Sofusa DoseConnect and Enbrel in people with Rheumatoid Arthritis, run by Sorrento Therapeutics, Inc. at 1 site 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 8 inclusion and 37 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 12 Apr 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence and severity of adverse events and their relationships to SOFUSA administration (time frame: Baseline through Week 12). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04559412.

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 12 Apr 2023; AzTrials last refreshed its copy on 7 Nov 2026.
