  • Patients with a history of HCV infection are eligible if they have completed curative antiviral treatment and have a viral load that is below the limit of detection.
  • HIV: Patients living with HIV infection are ineligible only if they have a CD4 count less than 350 cells/µL and a history of an AIDS-defining infection within the last 12 months. Patients with a CD4 count greater than 350 cells/µL or who have not had an AIDS-defining infection within the last 12 months are eligible. Eligible patients living with HIV should maintain effective anti-retroviral therapy.

About this study

The goal of this clinical research study is to determine if an investigational new drug, named ORB-011, developed by Orionis Biosciences is safe and can be tolerated in people diagnosed with an advanced solid tumor.

The study also aims to find the biologically optimal dose of the study medicine by assessing the safety and potential activity in the treatment of solid tumors.

There are three phases to this study: screening, treatment and end of treatment.

Read the detailed description

ORB-011 is a complex engineered biologic molecule that targets interferon alpha 2b activation specifically to type 1 conventional dendritic cells (cDC1). The interferon alpha 2b in ORB-011 is inactive to all other cell types but confers full activation in cis when bound to cDC1 cells which exclusively express CLEC9a, thereby eliminating the potential systemic toxicities caused by alpha interferon when binding to interferon receptors on other cells. ORB-1 is administered by intravenous (IV) infusion. In cancer patients, treatment may be repeated every 3 weeks.

Dose Escalation ORB-011ExperimentalORB-011 Dose Escalation Participants will be administered study drug at dose levels corresponding to their Cohort. Cohort 1 will be treated with the lowest dose, and the dose will be escalated for future cohorts once the previous dose has been observed not to be associated with DLTs. Up to 7 dose cohorts have been pre-specified. Doses from the escalation arms will be selected as RP2D candidates.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ORB-011 in people with Advanced Solid Cancer, run by Orionis Biosciences Inc at 2 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 17 inclusion and 30 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: finished, as of the sponsor's last update on 12 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Number of Adverse Events (AE) in patients dosed with ORB-011 (time frame: 12 months). 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?

On the ClinicalTrials.gov record for NCT05947474.

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 Jun 2026.
