Target enrollment:
0
Participant gender:
All
Summary
This phase I trial evaluates the feasibility of using hyperpolarized carbon C 13 pyruvate magnetic resonance imaging (MRI) in diagnosing patients with primary central nervous system lymphoma. This trial aims to see whether MRI using hyperpolarized carbon-13 pyruvate is safe and useful for detecting central nervous system lymphoma and evaluating response to treatment.

Criteria
Inclusion Criteria:

- For Patients in Cohort 1: Histologically proven PCNSL who have evidence of evaluable
disease based on a prior MR scan: measurable disease based on MRI is defined as
gadolinium enhancement of a central nervous system (CNS) lymphoma lesion (at least one
centimetre (cm) diameter).

- For Patients in Cohort 2: Histologically proven newly diagnosed PCNSL who will receive
standard treatment with high-dose methotrexate, temozolomide plus rituximab (MT-R).
These criteria will ensure validity of this study in terms of safety, evaluation of
clinically and radiographically relevant disease.

1. Patients must be > 18 years old and with a life expectancy > 12 weeks.

2. Patients are eligible provided they had histologic confirmation of CNS
non-Hodgkin lymphoma (NHL), DLBCL-type.

3. Measurable disease based on MRI that shows gadolinium enhancement of CNS lymphoma
lesion, (at least one cm diameter) within two weeks of enrollment, is mandatory.
Recent MRI must be eligible for review.

4. If patient requires dexamethasone, dose must be stable for >1 week prior to MR
studies.

5. Patients cannot have contraindication to MRI examinations or to lumbar puncture.
Concomitant involvement of cerebrospinal fluid/leptomeninges and intraocular
compartments is allowed.

6. Patients must have adequate bone marrow function (white blood cell count (WBC) >
3,000/µl, Absolute Neutrophil Count (ANC) > 1,500/mm3, platelet count of >
100,000/mm3, and adequate renal function (creatinine >50 millilitre(ml)/minute)
before starting therapy. These tests must be performed within 14 days prior to
Hyperpolarized Imaging scan.

7. Patients must not have any significant medical illnesses that in the
investigator's opinion cannot be adequately controlled with appropriate therapy,
would compromise the patient's ability to participate in this study or any
disease that will obscure toxicity or dangerously impact response to the imaging
agent.

8. Patients must not have New York Heart Association (NYHA) Grade II or greater
congestive heart failure

9. Patients must not have history of myocardial infarction or unstable angina within
12 months prior to study enrollment.

10. Patients must be eligible for treatment with high-dose methotrexate (dose between
1 gm/m2 - 8 gm/m2).

11. Each participant must sign an institutional review board-approved informed
consent document in accordance with federal and institutional guidelines.
Patients must sign an authorization for release of their protected health
information.

12. This study was designed to include women and minorities but was not designed to
measure differences of intervention effects. Males and females will be recruited
with no preference to gender. Minorities will actively be recruited to
participate. No exclusion to this study will be based on race.

13. Patients must not have a history of any other cancer (except non-melanoma skin
cancer or carcinoma in-situ of the cervix), unless in complete remission and off
of all therapy for that disease for >3 yrs.

14. Patients must not be pregnant or breast feeding. Women of childbearing potential
are required to obtain a negative pregnancy test within 14 days of Hyperpolarized
Imaging scan. Effective contraception (men and women) must be used in subjects of
childbearing potential.

Exclusion Criteria:

1. Subjects must be excluded from participating in this study if are not able to comply
with study and/or follow-up procedures.

2. Patients with baseline cardiovascular risk defined as the following:

1. Poorly controlled hypertension, defined as either systolic >170 or diastolic
>110.

2. Congestive Heart Failure >=Class III

3. Myocardial infarction within the past year

4. QT prolong
