  • 18 years of age.

Who cannot join

  • Receiving any other investigational agents which may affect patient's lymphocyte counts.
  • Pregnant women are excluded from this study because rhIL-7-hyFc has not been evaluated regarding its potential for teratogenic or abortifacients effects. There is a potential risk for adverse events in nursing infants secondary to treatment of the mother with the study drug, breastfeeding should be discontinued if the mother is treated with rhIL-7-hyFc.
  • Has an active viral infection requiring systemic treatment at screening.
  • Has active autoimmune disease or syndrome (i.e. moderate or severe rheumatoid arthritis, moderate or severe psoriasis, multiple sclerosis, myasthenia gravis, Guillain Barre syndrome, systemic lupus erythematosis, scleroderma, ulcerative colitis, Crohn's disease, autoimmune hepatitis, Wegener's etc.,) that requires systemic treatment at the time of screening. Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency) is not considered a form of systemic treatment. Subjects are permitted to enroll if they have vitiligo, resolved childhood asthma/atopy, type I diabetes mellitus, residual hypothyroidism due to autoimmune condition only requiring hormone replacement, psoriasis not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger.
  • Receipt of live attenuated vaccine within 30 days before the first dose of study treatment. Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, chicken pox, yellow fever, rabies, Bacillus Calmette-Guérin (BCG), Zoster, and typhoid vaccine. Seasonal influenza vaccines for injection are generally killed virus vaccines and are allowed; however, intranasal influenza vaccines (e.g. FluMist) are live attenuated vaccines and are not allowed.
  • Has clinically significant cardiac enzymes ([Tnl or TnT] or CK-MD)
  • Patients with a clinically significant EKG on screening triggering a echocardiogram which is also clinically significant

About this study

Official title: Effect of rhIL-7-hyFc on Increasing Lymphocyte Counts in Patients With Newly Diagnosed Non-severe Lymphopenic Gliomas Following Radiation and Temozolomide

The investigators have developed a phase I/II clinical trial to evaluate the effect of rhIL-7-hyFc on lymphocyte counts in patients with high grade glioma (HGG).

A phase I study will test whether rhIL-7-hyFc can be safely administered to patients with HGG. Six doses of rhIL-7-hyFc will be tested using a mix of Accelerated Phase and standard 3+3 dose-escalation design. The phase II portion to test effect of rhIL-7-hyFc on lymphocyte counts will use placebo-controlled randomization in HGG patients whose treatment include the standard radiation therapy (RT) and temozolomide (TMZ).

What is being measured

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

  1. Phase I Only: Safety and Tolerability of rhIL-7-hyFc as Measured by the Maximum Tolerated Dose (MTD) of rhIL-7-hyFc

    -The maximum tolerated dose (MTD) is defined as the dose level immediately below the non-tolerated dose. A total of at least 6 patients must be treated at a dose level for it to be considered the MTD.

    Measured: Within 30 days of treatment start

  2. Phase I: Safety and Tolerability of rhIL-7-hyFc as Measured by Number of Participants With Dose-limiting Toxicities (DLTs)

    -DLTs are defined in the protocol.

    Measured: Within 30 days of treatment start

  3. Randomized Phase II: Percent Change in Absolute Lymphocyte Count (ALC)

    Absolute lymphocyte count (ALC) is a laboratory test that measures the exact number of lymphocytes in a microliter (µL) of blood. Lymphocytes are a type of white blood cell that play a crucial role in the immune system.

    Measured: Baseline to Prior to adjuvant TMZ (approximately week 4)

  4. Phase II Expansion Arm: Progression-free Survival (PFS)

    -Defined from date of surgery to date of progression or death due to disease or date of last clinical follow up.

    Measured: Through completion of follow-up (estimated to be 5 years and 6 months)

Secondary outcomes (2)
  1. Phase I and Randomized Phase II: Immunogenicity as Measured by Anti-drug Antibodies (ADAs)

    • The formation of anti-drug antibodies (ADA) to rhIL-7-hyFc will be evaluated: BioAgilytix will perform both Elisa Binding (non-neutralizing) and neutralizing antibody assays according to their Standard Operating Procedure. The data will be presented if anti-drug antibodies are detected or not detected in the samples.
    • Week 1 will be prior to injection of 1st dose of rhIL-7-hyFc, week 13 will be prior to the 2nd dose of rhIL-7-hyFc, and week 45 will be 8 weeks after the last dose of rhIL-7-hyFc.

    Measured: Week 1, Week 13, Week 25, and Week 45

  2. Phase I: Percent Change in Absolute Lymphocyte Count (ALC)

    Absolute lymphocyte count (ALC) is a laboratory test that measures the exact number of lymphocytes in a microliter (µL) of blood. Lymphocytes are a type of white blood cell that play a crucial role in the immune system.

    Measured: Baseline to Prior to adjuvant TMZ (approximately week 4)

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing rhIL-7-hyFc, Temozolomide and Radiation therapy in people with Glioma, run by Washington University School of Medicine 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 14 inclusion and 7 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: under way, not looking for participants, as of the sponsor's last update on 25 Nov 2025. 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 combined 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.

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?

Yes. Results are posted in the registry (first posted 25 Nov 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Phase I Only: Safety and Tolerability of rhIL-7-hyFc as Measured by the Maximum Tolerated Dose (MTD) of rhIL-7-hyFc (time frame: Within 30 days of treatment start). The study lists 4 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 NCT03687957, which also lists 1 linked publication.

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 25 Nov 2025.
