Description

Summary

The primary objectives of this trial are to evaluate the safety and tolerability of sonodynamic therapy (SDT) using SONALA-001 and Exablate Type-2 device and to to determine the maximum tolerated dose (MTD) or recommended phase 2 dose (RP2D) of MR-Guided Focused Ultrasound (MRgFUS) energy in combination with SONALA-001 in subjects with diffuse intrinsic pontine glioma

Official Title

A Dose-escalation Study Examining the Safety, Pharmacokinetics, and Preliminary Efficacy of Ascending Drug and Energy Dose Combinations for Sonodynamic Therapy Using SONALA-001 in Combination With Exablate 4000 Type-2 MR-Guided Focused Ultrasound in Subjects With Diffuse Intrinsic Pontine Glioma

Keywords

Diffuse Intrinsic Pontine Glioma Glioma SONALA-001 (ALA) and MR-Guided Focused Ultrasound device (MRgFUS)

Open to people ages 5 years and up

  1. Newly diagnosed, radiographically typical DIPG, defined as a tumor with a pontine epicenter and diffuse involvement of more than 2/3 of the pons and without evidence of dissemination, are eligible with or without histologic confirmation.
  2. Subjects with pontine lesions that do not meet radiographic criteria will be eligible if there is histologic confirmation of DIPG.
  3. Subjects may be asked to agree to provide access to previously obtained biopsy results.
  4. If tumor status is unknown or archival tumor tissue is not available, subjects may be asked to agree to submit a post-mortem biopsy specimen to enable molecular profiling of tumor.
  5. Prior treatment consisting of a minimum of 54 Gy standard focal radiotherapy administered over 42-49 days.
  6. Must be ≥ 4 weeks and ≤ 16 weeks post radiotherapy and must have recovered from acute effects to CTCAE Grade 1 or baseline prior to Day 1.
  7. Must have stable to improved imaging by RAPNO criteria and be on a stable to decreasing dose of steroids (maximum dexamethasone of 1 mg/m2/day) prior to Day 1, as obtained during the Screening period.

  8. A minimum head circumference of 52 cm. Subjects with a minimum head circumference of 52 cm, younger than 5 years old, may be eligible after discussion with the medical monitor.
  9. An Overall Skull Density Ratio greater than 0.45 (±0.05) as calculated from the screening CT.
  10. Females of childbearing potential (FOCP) must have a negative serum or urine pregnancy test at screening. Subjects of childbearing or child fathering potential must be willing to use highly effective birth control during the entire study. Acceptable forms of birth control include hormonal contraceptives (oral, injectable, transdermal or intravaginal) or intrauterine device (IUD) for at least one week prior to ALA SDT, condom and spermicidal or diaphragm and spermicidal. Other acceptable forms of birth control include a) abstinence for subjects who are not sexually active or b) if the subject is in a monogamous relationship with a partner who is sterile (e.g., vasectomy performed at least 6 months prior to subject's ALA SDT treatment). Subjects who become sexually active or begin to have relations with a partner who is not sterile during the trial must agree to use an effective form of birth control for the duration of the study. FOCP taking hormonal therapy must be on treatment for at least 12 weeks prior to study entry and must not change their dosing regimen during the study.
  11. Ability to provide written, signed, and dated (personally or via a legally authorized representative) informed consent/and assent at screening as applicable to participate in the study.
  12. Karnofsky Performance Scale (KPS for > 16 years of age) or Lansky Performance Score (LPS for ≤ 16 years of age) assessed within 14 days of Visit 1 must be ≥ 50%. Subjects who are unable to walk because of neurologic deficits, but who are up in a wheelchair, will be considered ambulatory for the purpose of assessing the performance score.
  13. . Subjects must have adequate organ and marrow function as defined below:
  14. Absolute neutrophil count ≥ 1,000/mm3, without the use of GCSF within 7 days prior to Day 1.

  15. Platelets ≥ 100,000/ mm3 (unsupported, defined as no platelet transfusion within 7 days prior to Day 1)

  16. Hemoglobin ≥ 8 g/dl (may have received last transfusion within 7 days prior to Day 1.)
  17. Total bilirubin ≤ 1.5 times institutional upper limit of normal (ULN)
  18. ALT(SGPT) < 3 x institutional ULN
  19. AST(SGOT) < 3 x institutional ULN
  20. Albumin ≥ 3 g/dl
  21. Potassium ≥ lower limit of normal LLN
  22. Serum total calcium (correct for serum albumin) or ionized calcium ≥ LLN
  23. Renal Function as defined below:
  24. Age 5-17 years: GFR ≥ 70 mL/min/1.73m2as estimated by Schwartz formula (Schwartz, 2009). If eGFR is abnormal for age based on Schwartz formula, accurate measurement should be obtained by 24 hour creatinine clearance.
  25. Age ≥ 18 years: Creatinine clearance (CLcr) ≥ 60 mL/min/1.73m2as estimated by the Cockcroft-Gault (C-G) equation. If estimated CLCr is abnormal, accurate measurement should be obtained by 24 hour creatinine clearance.
  26. . Cardiac Function as defined below:
  27. Left ventricular ejection fraction ≥ 50 by gated radionuclide study OR shortening fraction of ≥ 27% by echocardiogram
  28. Presence of no ventricular arrhythmias except for benign premature ventricular contractions.
  29. QTc (Frideriica) interval < 450 ms.
  30. . All colony-forming growth factor(s) (i.e., filgrastim, sargramostim or erythropoietin) must have been discontinued for at least 7 days prior to Day 1 or 14 days if PEG formulations were received.
  31. . An understanding, ability, and willingness to fully comply with study procedures and restrictions.
