About this study

Official title: A Phase 2 Study Examining AGEN2034 as a Single-Agent and in Combination With AGEN1884 in Patients With Recurrent, Inoperable Angiosarcoma

This Phase 2, open-label study is designed to examine the efficacy and safety of single-agent AGEN2034 and combination AGEN2034 + AGEN1884 in patients with recurrent, inoperable or metastatic Angiosarcoma (AS).

Read the detailed description

This Phase 2, open-label study is designed to examine the efficacy and safety of single-agent AGEN2034 and combination AGEN2034 + AGEN1884 in patients with recurrent, inoperable or metastatic AS.

Three cohorts will be enrolled into 2 Parts of the study as follows:

Part 1

  • Cohort 1: Qualifying patients that are checkpoint inhibitor naïve will be enrolled into single-agent AGEN2034
  • Cohort 2: Qualifying patients that are inhibitor (PD-1/L1) resistant will be enrolled into combination AGEN2034 + AGEN1884

Part 2

  • Cohort 3: Qualifying patients that are checkpoint inhibitor naïve will be enrolled into combination AGEN2034 + AGEN1884. Part 2 will begin enrollment after enrollment in Part 1 is completed

The study will be conducted in 2 parts:

In Part 1, checkpoint inhibitor naïve patients will be treated with single-agent AGEN2034 (Cohort 1) and patients resistant to PD-1/PD-L1 (defined as prior progression on PD 1/PD-L1 treatment) will be treated with combination of AGEN2034+AGEN1884 (Cohort 2). Patients from Cohort 1 who experience PD may be considered (as PD-1 resistant) for transition to Cohort 2.

In Part 2, the study will enroll checkpoint inhibitor naïve patients for treatment with combination AGEN2034+AGEN1884 (Cohort 3). Part 2 will begin enrollment after enrollment in Part 1 is completed.

All patients will receive study treatment for up to 2 years until confirmed disease progression, unacceptable toxicity, or until the patient wishes to withdraw consent for any reason. Patients will be followed for safety at 30 and 90 days, and for survival every 2 months for at least 12 months from their last dose of study treatment. Each treatment cycle will be 6 weeks.

An IRC will be established to adjudicate tumor response based on imaging studies, photography, and clinical response. The primary endpoints will be based on the IRC assessment of response per RECIST v1.1.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing AGEN2034 and AGEN1884 in people with Angiosarcoma, run by Agenus Inc..

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 30 inclusion and 23 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: withdrawn, as of the sponsor's last update on 11 Jan 2022. Status can change between updates, so confirm with the study contact before making plans.

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 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?

The study was withdrawn before enrolling participants, so there are no results.

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?

Response rate of single-agent AGEN2034 and combination AGEN2034 + AGEN1884 (time frame: 48 months). 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 NCT04607200.

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 11 Jan 2022.
