Brief summary

The purpose of this study is to learn more about the effectiveness and side effects of lithium treatment for subjects with low-grade neuroendocrine tumors.

Detailed description

Lithium 300mg by mouth, three times daily, escalating to a lithium level of 0.8-1.0; Continue until progressive disease/unacceptable toxicity;Evaluate q 8 weeks.

Interventions

DRUGLithium Carbonate

Lithium 300mg PO TID escalating to a lithium level of 0.8-1.2. Lithium carbonate will be administered the first week at 300 mg flat dose three times each day. A serum lithium level will be checked after 4-5 days of treatment by drawing a blood sample prior to the morning dose of lithium. Evaluate every 8 weeks.

Inclusion criteria

* Must have histologically confirmed metastatic low-grade neuroendocrine neoplasms. Small cell lung cancers, paragangliomas and pheochromocytomas are excluded. Pathologic diagnosis must be confirmed at the University of Wisconsin Carbone Cancer Center (UWCCC). Grading must be confirmed by pathologic review performed at UWCCC. * Must have measurable disease * Must have radiographic evidence of disease progression following any prior systemic therapy, chemoembolization, bland embolization, surgery, or observation. * Must be ≥ 4 weeks from the completion of major surgery, chemotherapy, or other systemic therapy or local liver therapy to study registration * Must be ≥ 3 weeks from the completion of radiation therapy to study registration * The following laboratory values are to be obtained within 14 days prior to registration: Absolute neutrophils count (ANC) ≥ 1000/mm3; Platelets ≥ 75,000/mm3; Hemoglobin ≥ 8.0 g/dL; Total bilirubin less than or equal 2.0 X the upper limit of normal (ULN); AST less than or equal to 3 X ULN or less than or equal 5 X ULN if liver metastases are present; Creatinine less than or equal ULN; Serum sodium within normal limits * PS = 0-2 * Capable of understanding the investigational nature, potential risks and benefits fo the study and able to provide valid informed consent. * Must have available tissue specimens to be analyzed for pathologic confirmation. * Age ≥ 18 years. * Women must not be pregnant or lactating. * Women of childbearing potential and sexually active males are required to use an accepted and effective method of contraception. * Patients must not have known history of allergic reactions or adverse reactions to Lithium or derivatives. * Patients are not allowed to be on concurrent chemotherapy or radiation therapy. * Patients are excluded if they have any of the following: Gastrointestinal tract disease resulting in an inability to take oral medication (i.e. ulcerative disease, uncontrolled nausea, vomiting, diarrhea, bowel obstruction, or inability to swallow the tablets. History of hypothyroid disease Significant, active cardiac disease * Patients must not be taking the following medications: diuretics, ACE inhibitors, NSAIDs (except aspirin or sulindac), neuroleptics, tetracycline, COX2 (cyclooxygenase-2) inhibitors, citalopram, clovoxamine, escitalopram, femoxetine, fluoxetine, fluvoxamine, paroxatine, sertraline, and zimeldine. * Must be willing to undergo a tumor biopsy pre and post therapy. * Patients with a concurrent malignancy are allowed on study as long as the patient is not undergoing active treatment for their disease. * Patients already taking Lithium for any reason are not allowed on study.

MeasureTime frameDescription
Tumor Response Rate Measured by the Response Evaluation Criteria in Solid Tumors (RECIST)Up to 4 yearsPer Response Evaluation Criteria in Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR) \>=30% decrease in the sum of the longest diameter of target lesions; Progressive Disease (PD) \>=20% increase in the sum of the longest diameter of target lesions; Stable Disease (SD), small changes that do not meet the above criteria.

Secondary

MeasureTime frameDescription
Progression Free Survival (PFS)Up to 4 yearsProgression is defined using Response Evaluation Criteria in Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions. Progression free survival is measured from the date of entry on the study to the appearance of new metastatic lesions or objective tumor progression. If a participant did not experience an event of disease progression or death at the time of analysis (03/10/2011), then the patient's data was censored at the date of the last available evaluation.
Overall Survival (OS)Up to 4 yearsOverall survival for a participant is defined as the number of days from the day of first Lithium administration to the participant's death. As of the time of analysis (03/10/2011), median overall survival duration was not reached.

Lithium
Lithium carbonate was dosed on a flat scale of mg/day and not by weight or body surface area (BSA). Lithium carbonate was provided as a 300mg tablet and was taken daily without breaks in treatment. Lithium Carbonate: Lithium 300mg PO TID escalating to a lithium level of 0.8-1.2. Lithium carbonate was administered the first week at 300 mg flat dose three times each day. A serum lithium level was checked after 4-5 days of treatment by drawing a blood sample prior to the morning dose of lithium. Evaluated every 8 weeks.

Progression is defined using Response Evaluation Criteria in Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions. Progression free survival is measured from the date of entry on the study to the appearance of new metastatic lesions or objective tumor progression.
