Summary

The purpose of this study is to determine the maximum tolerated dose (MTD) and select optimal biological doses (OBD) of the study drug NT-I7 in High Grade Glioma patients with severe lymphopenia, as well as to test the effect of NT-I7 on the CD4 counts of patients in comparison to control participants. This study has both a Phase I and Pilot component.

Description

PRIMARY OBJECTIVES:

Phase I: To determine the MTD (Maximum Tolerated Dose) and select optimal biological doses (OBD) of NT-I7 in HGG patients with severe lymphopenia

Pilot Study: To test the effect of NT-I7 on CD4 counts compared to control

SECONDARY OBJECTIVES:

  1. To evaluate the optimal biological dose of NT-I7
  2. To evaluate the effect of concurrent dexamethasone
  3. To evaluate the duration of effect on CD4 counts (up to 6 months)
  4. To evaluate the total lymphocyte counts over time and serial T cell lymphocyte subtypes and the effect on T cell repertoire (up to 6 months)
  5. To evaluate the serial cytokine levels (up to 6 months)
  6. To evaluate the impact of adjuvant temozolomide on NT-I7 effects on CD4 counts
  7. To evaluate anti-drug antibodies
  8. To evaluate the pharmacokinetic profile of NT-I7 after intramuscular administration in this patient population
  9. To evaluate the safety and toxicity of NT-I7 in patients with high grade glioma

OUTLINE: Patients are assigned to 1 of 2 groups depending on their use of dexamethasone.

GROUP A: Patients not on dexamethasone (or equivalent of an alternative corticosteroid), or on a dose lower than a physiologic dose (=< 0.75 mg daily)

GROUP B: patients who require dexamethasone (or equivalent of an alternative corticosteroid) => 4 mg daily

Patients must have been on the group assignment dose of corticosteroids for at least 5 days prior to the dose of NT-I7. Corticosteroid dose changes prior to the start of treatment are allowed as long as they do not alter patient's group assignment.

PHASE I TREATMENT PLAN

All patients (both Groups A and B) will be given a single dose of NT-I7 by intramuscular injection starting at 60 g/kg, within one week after completing concurrent RT+TMZ and before starting adjuvant TMZ treatment, during the standard post-radiation break. Following this period, as per standard treatment, patients will go on to receive adjuvant temozolomide on Days 1-5 of 28-day cycles for 6 cycles. There should be about six weeks between the study injection and the start of adjuvant temozolomide; thus the start of adjuvant TMZ will be approximately two weeks later than the usual start, which is 4 weeks post-end of radiation. Patients who are delayed from receiving or are not able to receive adjuvant TMZ treatment may continue on study; adjuvant TMZ treatment is not a requirement for participation.

PILOT STUDY TREATMENT PLAN

GROUP A: participants will be given either a placebo (NT-I7 diluent) or one dose of NT-I7 at the Phase I Group A OBD by intramuscular injection within one week after completing concurrent RT+TMZ and before starting adjuvant TMZ treatment, during the standard post-radiation break.

GROUP B: participants will be given one dose of NT-I7 at the Phase I Group B OBD by intramuscular injection within one week after completing concurrent RT+TMZ and before starting adjuvant TMZ treatment, during the standard post-radiation break.

After completion of study treatment, patients are followed up every 2 months for 2 years and then every 6 months thereafter.

Patients must have CD4 =< 300 cells/mm^3 in the last week (7 days) of standard radiation + temozolomide treatment (58-60 Gy radiation with temozolomide 75 mg/m2 daily during radiation)
Absolute neutrophil count >= 1,000/mcL
Platelets >= 50,000/mcL (need to confirm before administering study drug)
Hemoglobin >= 9 g/dL
Total bilirubin =< institutional upper limit of normal
Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 x institutional upper limit of normal
Creatinine =< institutional upper limit of normal OR creatinine clearance >= 60 ml/min/1.73 m^2 for patients with creatinine levels above institutional normal
Activated partial thromboplastin time (APTT) or partial thromboplastin time (PTT) =< 1.5 x institutional upper limit of normal

Patients must be able to provide written informed consent
Women of childbearing potential must have a negative serum pregnancy test prior to study entry; women of childbearing potential and men must agree to use two birth control methods (either two barrier methods or a barrier method plus a hormonal method) or abstinence prior to study entry and for the duration of study participation (through at least 90 days after the last study injection); should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
Dexamethasone dose must be provided for treatment group assignment
Group A: patients not on dexamethasone or on a dose =< 0.75 mg daily (or equivalent of an alternative corticosteroid)
Group B: patients who require dexamethasone >= 4 mg daily (or equivalent of an alternative corticosteroid) Patients must have been on the group assignment dose of corticosteroids for at least 5 days prior to the dose of NT-I7; corticosteroid dose changes prior to the start of treatment are allowed as long as they do not alter patient's group assignment
