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 2.0 device and 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

Funding Source - FDA OOPD

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 2.0 MR-Guided Focused Ultrasound in Subjects With Diffuse Intrinsic Pontine Glioma (DIPG)

Eligibility

You can join if…

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 ⅔ of the pons and without evidence of dissemination, are eligible with or without histologic confirmation.
    • The diagnosis imaging scan must be reviewed by the study site's neuroradiologist and the principal investigator. The diagnosis imaging scan must subsequently be sent to the study central imaging vendor.
    • Subjects who present with DIPG and dissemination at diagnosis, but after completion of radiotherapy have no dissemination on neuroimaging at screening, are considered eligible.
    • Subjects with pontine lesions that do not meet radiographic criteria will be eligible if there is histologic confirmation of DIPG.
    • Subjects may be asked to agree to provide access to previously obtained biopsy results.
    • 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.
  2. Prior treatment consisting of a minimum of 54 Gy standard focal radiotherapy administered over 42-49 days.
  3. Must be ≥ 4 weeks and ≤ 24 weeks post radiotherapy and must have recovered from acute effects to CTCAE (version 5) Grade 1 or baseline prior to Day 1.
  4. Must have stable to improved imaging by RAPNO criteria comparing the scan obtained post radiotherapy to the scan obtained during the screening period. The comparison of diagnosis imaging scan and screening imaging scan must be reviewed by the study site's neuroradiologist and the principal investigator. If subjects present within 3 months after completion of radiotherapy and the comparison of the diagnosis scan to the screening scan is consistent with RAPNO progression but pseudoprogression is a consideration, then the subject can be re-screened if the subject falls out of the screening window.
  5. Subjects who are on steroids must be on a stable to decreasing dose of steroids (maximum dexamethasone of 1 mg/m2/day) prior to Day 1.
  6. Minimum of 5 years of age. Subjects younger than 5 years old may be eligible after discussion with the Sponsor Medical Monitor/designee.
  7. A minimum head circumference of 52 cm as measured by physical exam. Subjects with a minimum head circumference smaller than 52 cm may be eligible after discussion with the Sponsor Medical Monitor/designee.
  8. 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.
  9. 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.

    10. Karnofsky Performance Scale (KPS for > 16 years of age) or Lansky Performance Score

    (LPS for ≤ 16 years of age) assessed within 14 days of Day 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.

    11. Subjects must have adequate organ and marrow function as defined below:

    • Absolute neutrophil count ≥ 1,000/mm3, without the use of myeloid growth factors (e.g. GCSF) within 7 days prior to Day 1.
    • Platelets ≥ 100,000/mm3 (unsupported, defined as no platelet transfusion within 7 days prior to Day 1).
    • Hemoglobin ≥ 8 g/dl maintained without the need for erythropoietin stimulating agents (may have received last transfusion within 7 days prior to Day 1).
    • Total bilirubin ≤ 1.5 times institutional upper limit of normal (ULN); in subjects with Gilbert syndrome, total bilirubin >1.5 ULN as long as direct bilirubin is normal.
    • Alanine aminotransferase (ALT) < 3 x institutional ULN.
    • Aspartate aminotransferase (AST) < 3 x institutional ULN.
    • Albumin ≥ 3 g/dl.
    • Potassium ≥ lower limit of normal (LLN).
    • Serum total calcium (correct for serum albumin) or ionized calcium ≥ LLN.
    • Renal function as defined below:
      • Age 5-17 years: GFR ≥ 70 mL/min/1.73m2 as 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 (CrCl).
      • Age ≥ 18 years: CrCl ≥ 60 mL/min/1.73m2 as estimated by the Cockcroft-Gault (C-G) equation. If estimated CrCl is abnormal, accurate measurement should be obtained by 24 hour CrCl.
      • Cardiac function as defined below:
    • Left ventricular ejection fraction ≥ 50% by gated radionuclide study OR shortening fraction of ≥ 27% by echocardiogram.
    • Presence of no ventricular arrhythmias except for benign premature ventricular contractions.
    • QTcF (Fridericia) interval < 450 ms.
      1. 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.
        1. An understanding, ability, and willingness to fully comply with study procedures and restrictions.
        2. Subjects with Ommaya Reservoirs, VP shunts (nonmetallic) or similar will have a technical evaluation of the screening non-contrast CT scan of the head conducted by an Insightec trained technical Research and Development (R&D) specialist which will be provided to SonALAsense. This information will be included in the eligibility review by SonALAsense and designee. During mapping of the target area, if the machine determines that it cannot treat within the safety limits of the system (i.e., skull area, number of elements, etc.), the device will signal that it cannot initiate a sonication at that target and the investigator will determine whether to proceed with the treatment.

The last dose must have been administered no later than 14 days prior to Day 1. See Section 6 (Prior and Concomitant Treatment) for a list of prohibited and restricted medications.
