- Registration Number
- NCT03687957
- Lead Sponsor
- Washington University School of Medicine
- Brief Summary
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).

Inclusion Criteria
-
World Health Organization (WHO) grade III, grade IV, and high risk grade II gliomas that require RT and TMZ treatment.

Exclusion Criteria
- 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

- Primary Outcome Measures
Name Time Method Phase I: Safety and tolerability of rhIL-7-hyFc as measured by the maximum tolerated dose (MTD) - Phase I only Completion of enrollment of phase I portion of study (estimated to be 1 year) -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.
Randomized Phase II: Percent increase of absolute lymphocyte count Prior to adjuvant TMZ (approximately week 4) Phase I: Safety and tolerability of rhIL-7-hyFc as measured by dose-limiting toxicities (DLTs) 30 days from the date when patients receive the 1st dose of rhIL-7-hyFc administration (estimated to be 29 weeks) -DLT will be defined as ≥ grade 3 non-dermatological and non-hematological AEs that occur within 30 days from the date when patients receive the 1st dose of rhIL-7-hyFc administration and are concluded to be possibly, likely or definitely related to the drug regimen that occurs during cycle 1, with severity graded according to the Common Terminology Criteria for Adverse Events (CTCAE) 5.0.
Phase II Expansion Cohort: Progression-free survival (PFS) Through completion of follow-up (estimated to be 5 years and 6 months) -Defined from date of surgery to date of progression or death due to disease or date of last clinical follow up.
- Secondary Outcome Measures
Name Time Method Phase I: Absolute lymphocyte count (ALC) 1 year Phase I and Randomized Phase II: Immunogenicity as measured by anti-drug antibodies Baseline through Week 14 -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.
