Condition(s) targeted: High Grade Glioma

Intervention: Trans Sodium Crocetinate (TSC) (Drug)

Phase: Phase 1

Status: Terminated

Sponsored by: Diffusion Pharmaceuticals LLC

Summary

The purpose of this study is to evaluate the impact of Trans Sodium Crocetinate (TSC) on oxygen levels in brain tumor tissue in patients with high grade glioma. The proposed clinical indication for TSC is a radiation sensitizer for the treatment of cancerous tumors.

Clinical Details

Official title: Open-label Study to Determine the Effect of Trans Sodium Crocetinate (TSC) on Intra-tumoral Oxygen Concentration, Tolerability, and Pharmacokinetics of TSC in Post-operative Patients With High Grade Glioma (HGG)

Study design: Allocation: Non-Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Basic Science

Primary outcome:

Change from baseline in tumor tissue oxygen monitoring recordings

Safety assessments (laboratory tests)

Secondary outcome:

Pharmacokinetic assessments

Tumor hypoxia biomarkers (HIF 1-alpha, osteopontin, carbonic anhydrase IX)

Detailed description: In this open-label, one-site study, up to 48 patients with high grade glioma (HGG) who are undergoing biopsy or partial debulking of the tumor as part of standard of care will have an oxygen monitoring probe placed in residual tumor tissue. Oxygen levels in the tumor tissue will be measured prior to and after administering a single bolus injection of TSC. Safety assessments will occur throughout the trial, including at a 7 to 14 day follow-up visit. Pharmacokinetic assessments will be performed prior to and during the first 24 hours after TSC dosing.

Eligibility

Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.

Criteria:

Inclusion Criteria:

- At least 18 years old.

- Prior histological diagnosis of high grade glioma (HGG) with prior initial treatment

and radiation therapy for HGG; recurrence of HGG suspected, and care plan includes surgical procedure.

- Undergoing surgical procedure for clinical reasons, and gross surgical resection not

expected.

- Neurosurgeon is planning stereotactic biopsy or tumor debulking for clinical reasons;

frozen tissue confirmation of malignancy during this operative procedure is necessary.

- Neurosurgeon evaluates that placement of oxygen monitoring probe after biopsy or

debulking can be done safely without complications.

- Contrast enhancing disease on MRI within 21 days prior to enrollment.

- Karnofsky Performance Score ≥ 60 at Screening.

- Recovered from toxicity of prior antineoplastic therapy, and off cytotoxic

chemotherapy for 7 days prior to Screening.

- Recovered from prior radiotherapy and had at least 21 days elapse since completion of

radiotherapy prior to Screening.

- Recovered from prior surgery for their brain tumor in investigator's clinical

judgment.

- If female, negative serum or urine pregnancy test at Screening.

- Within 2 weeks of starting study, hematologic and renal functions as specified:

Absolute neutrophil count ≥ 1500/mm3, platelets ≥ 100,000/mm3, hemoglobin ≥ 9. 0g/dL, creatinine ≤ 1. 7mg/dl, serum bilirubin ≤ 1. 5mg/dL, blood urea nitrogen within 2 times the upper limit of normal, transaminases ≤ 4 times above the upper limits of the institutional norm, and prothrombin time and partial thromboplastin time within institutional norm or below.

- Patient or patient's medical power of attorney provided written consent to

participate in the study.

- Mini Mental Status Exam score ≥ 15.

Exclusion Criteria:

- Pregnant or lactating.

- Receiving concurrent cytotoxic chemotherapy for their tumor within 7 days prior to

Screening, or decision is made at the time of surgery to treat with other modality of treatment (e. g., gliadel wafers).

- Serious concurrent infection or medical illness which would jeopardize the ability of

the patient to safely participate.

- Behavioral, cognitive, or psychiatric disease or personal situation that might

interfere with optimal participation.

- Cannot undergo an MRI.

- Received an investigational drug not approved for human use by the FDA within 30 days

of enrollment.

- Previously received TSC.
