Inclusion Criteria:
DIPG Subjects:
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 (subjects ≤ 21 years of age) and mRANO
(subjects > 21 years of age) 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/mRANO 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

accurate measurement should be obtained by 24-hour creatinine clearance
(CrCl).

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.
