- For Part B, participants must have one of the following diagnoses histologically
confirmed:
- Neuroblastoma with evidence of Mycn/Myc positivity based on any of the following:

Hospital Los Angeles (CHLA) Clinical Pathology Laboratory; or
- Myc expression > 1+ according to validated assay in CHLA Clinical Pathology
Laboratory.
- One of the following mature B cell lymphoma diagnoses:
- Diffuse large B cell lymphoma
- Burkitt lymphoma
- Participants must have disease that is relapsed or refractory and for which standard
curative or palliative measures do not exist or are no longer effective.
- Patients must have fully recovered from the acute toxic effects of all prior
anti-cancer therapy except organ function as noted in Section 3.1.6). Patients must
meet the following minimum washout periods prior to enrollment:
- Myelosuppressive chemotherapy: At least 14 days after the last dose of
myelosuppressive chemotherapy (42 days for nitrosourea or mitomycin C).
- Radiotherapy:
- At least 14 days after local palliative XRT (small port);
- At least 90 days must have elapsed after prior TBI, craniospinal XRT or if >50%
radiation of pelvis;
- At least 42 must have elapsed if other substantial BM radiation;
- At least 42 days must have passed since last MIBG or other radionuclide therapy.
- Small molecule biologic therapy: At least 7 days following the last dose of a biologic
agent. For agents with known adverse events occurring beyond 7 days, this duration
must be extended beyond the time in which adverse events are known to occur. If
extended duration is required, this should be discussed and approved by the study
chair.
- Monoclonal antibody: At least 21 days after the last dose of anitbody
- Myeloid growth factors: At least 14 days following the last dose of long-acting growth
factor (e.g. Neulasta) or 7 days following short-acting growth factor.
- Stem Cell Infusion or Cellular Therapies: The patient must have no evidence of graft
versus host disease and at least 42 days must have elapsed after transplant, stem cell
infusion, or cellular therapy.
- Major Surgery: At least 3 weeks from prior major surgical procedure. Note: Biopsy and
central line placement/removal are not considered major.
- PI3K and HDAC inhibitors: The patient must not have received prior CUDC-907 therapy.
Prior treatment with individual PI3K or HDAC inhibitors is allowed. Patients must not
have received therapy with the combination of PI3K and HDAC inhibitors.
- Participants must have normal organ function as defined below.
- Bone Marrow Function:
- Absolute neutrophil count =1,000/uL
- Platelets =75,000/uL and transfusion independent, defined as not receiving a
platelet transfusion for at least 5 days prior to CBC documenting eligibility.
- Hepatic Function:
- Total bilirubin = 1.5 x upper limit of normal for age
- ALT (SGPT) = 135 U/L For the purpose of this study, the ULN for ALT is 45 U/L
- Serum albumin > 2 g/dL
- Renal Function:
--A serum creatinine based on age/gender as follows: Age Maximum Serum Creatinine
(mg/dL) Male Female
1. to < 2 years 0.6 0.6
2. to < 6 years 0.8 0.8
6 to < 10 years 1 1 10 to < 13 years 1.2 1.2 13 to < 16 years 1.5 1.4
= 16 years 1.7 1.4 OR
--Creatinine clearance = 70 mL/min/1.73 m2 for participants with creatinine levels
above institutional normal.
- Adequate Cardiac Function: QTc < 480 msec
- Adequate GI Function: Diarrhea < grade 2 by CTCAE version 4
- Adequate Metabolic Function: Fasting glucose < grade 2 (< 160 mg/dL or < 8.9 mmol/L)
without the use of antihyperglycemic agents.
- Additional Agent-Specific Requirements
- Patients must be able to swallow either intact capsules or mini-tabs without chewing.
- In order to limit dose deviations due to rounding, patients must have a body surface
area of at least 0.5 m2
- For patients with CNS tumors (primary or metastatic), any baseline neurologic deficits
(including seizure) must be stable for at least one week prior to study enrollment.
- Ability to understand and/or the willingness of the patient (or parent or legally
authorized representative, if minor) to provide informed consent, using an
institutionally approved informed consent procedure.
Exclusion Criteria:
- Patients must not be receiving any of the following concomitant medications:
- Pharmacologic doses of systemic corticosteroids unless for CNS metastatic or primary
disease. For patients with CNS metastatic or primary tumors receiving corticosteroids,
they should be on a stable or decreasing dose over the 7 days prior to registration
and meet criteria.
- For all patients, receipt of systemic physiologic replacement steroids, topical and/or
inhaled corticosteroids is acceptable.
- Non-steroidal anti-inflammatory drugs, oral anticoagulants, and therapeutic heparins.
- Pregnant participants will not be entered on this study given that the effects of
CUDC-907 on the developing human fetus are unknown.
- Because there is an unknown but potential risk for adverse events in nursing infants
secondary to treatment of the mother with CUDC-907, breastfeeding mothers are not
eligible.
- Participants of child-bearing or child-fathering potential must agree to use adequate
contraception (hormonal birth control; intrauterine device; double barrier method; or
total abstinence) throughout their participation, including up until 30 days after
last dose of CUDC-907.
- History of allergic reactions attributed to compounds of similar chemical or biologic
composition to CUDC-907.
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active
infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac
arrhythmia, or psychiatric illness/social situations that would limit compliance with
study requirements. Note that patients who have had prior allogeneic transplantation
are required to have CMV PCR testing performed during screening. A positive screen
would be evidence of an active infection and would render the patient ineligible.
- Patients with a known history of HIV, hepatitis B, and/or hepatitis C (testing not
required as part of screening).
- Patients with a known history of type 1 or type 2 diabetes mellitus.
- Patients with gastrointestinal disease or disorder that could interfere with
absorption of CUDC-907, such as bowel obstruction or inflammatory bowel disease.
