About this study

Official title: A Phase 1 Study of the PD-L1xCD27 Bispecific Antibody CDX-527 in Patients With Advanced Malignancies

This is an open-label, non-randomized, multicenter, dose-escalation and expansion study in patients with selected solid tumors.

Read the detailed description

This study will determine the safety, tolerability and activity of CDX-527.

Eligible patients that enroll to the dose-escalation portion of the study will be assigned to one of several dose levels of CDX-527. The dose-escalation part of the study will determine the safety profile of CDX-527 and determine which dose(s) of CDX-527 will be studied in the expansion part of the study.

The expansion part of the study will enroll eligible patients with certain solid tumors to be treated at dose(s) identified during dose-escalation

Up to 40 patients will be enrolled. All patients enrolled in the study will be closely monitored to determine if there is a response to the treatment as well as for any side effects that may occur.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CDX-527Drug

    CDX-527 is administered by infusion every 2 weeks

Study groups in NCT04440943
Study groupRoleWhat they receive
CDX-527ExperimentalDose-escalation phase: Eligible patients will receive CDX-527 treatment based on cohort assigned until progression or intolerance. Expansion phase: Patients will receive CDX-527 at the dose level(s) chosen during the escalation phase.
Receives: Drug: CDX-527

What is being measured

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

  1. Safety and Tolerability of CDX-527 as assessed by CTCAE v5.0

    The rates of drug-related adverse events will be summarized and maximum tolerated dose will be determined.

    Measured: From first dose through 28 days after last dose

Secondary outcomes (7)
  1. Objective Response Rate

    The percentage of patients who achieve a confirmed immune complete response (iCR) or immune partial response (iPR)

    Measured: Every 8 weeks starting with first dose until disease progression, assessed up to approximately 1-2 years.

  2. Clinical Benefit Rate

    The percentage of patients who achieve best response of confirmed iCR or iPR, or immune stable disease (iSD) for at least four months

    Measured: Every 8 weeks, starting with first dose until disease progression, assessed up to approximately 1-2 years.

  3. Duration of Response

    The interval from which measurement criteria are first met for iCR or iPR until the first date that progressive disease is objectively documented

    Measured: First occurrence of a documented objective response to disease progression or death (up to approximately 1-2 years)

  4. Progression-free Survival

    The time from start of study drug to time of progression or death, whichever occurs first

    Measured: From the first dose to the first occurrence of disease progression or death due to any cause (up to approximately 1-2 years)

  5. Overall Survival

    The time from start of study drug to death

    Measured: The time from start of study drug to death from any cause (up to approximately 1-2 years)

  6. Immunogenicity Evaluation

    Serum samples will be obtained for assessment of human anti-CDX-527 antibodies

    Measured: Prior to the first dose of study treatment, then intermittently before dosing, and up to 60 days after the last dose

  7. Pharmacokinetic Evaluation

    CDX-527 serum concentrations will be measured at specified visits.

    Measured: Before and after dosing, with additional timepoints after the first two doses, then intermittently before dosing and up to 60 days after the last dose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing CDX-527 in people with Non-small Cell Lung Cancer and Breast Cancer, run by Celldex Therapeutics at 5 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 5 inclusion and 14 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 18 Jun 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 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?

Safety and Tolerability of CDX-527 as assessed by CTCAE v5.0 (time frame: From first dose through 28 days after last dose). 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 18 Jun 2023.
