This phase I/II trial studies the effects and safety of giving lithium carbonate (lithium) to patients with small cell lung cancer (SCLC) undergoing radiation therapy to the brain (PCI; prophylactic cranial irradiation). PCI is used to prevent cancer metastases from returning in the brain. This treatment can cause short-term memory problems by damaging the hippocampus. Lithium may help prevent or lessen memory problems caused by PCI by protecting the hippocampus.

Condition Intervention Phase
Small Cell Lung Carcinoma Drug: Lithium Carbonate Radiation: Prophylactic cranial irradiation Phase 1 Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Supportive Care
Official Title: Phase I/II Trial of Lithium as a Neuroprotective Agent for Patients With Small Cell Lung Cancer (SCLC) Treated With Prophylactic Cranial Irradiation (PCI)

Primary Outcome Measures:
  • Dose-limiting toxicities of lithium (DLTs), (safety lead-in) [ Time Frame: 3 weeks ]
    Graded and described using National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) v 4. Safety will be defined as < 2 patients experiencing DLTs of the first 6 treated.

  • Rate of immediate recall memory deterioration at 3 months, (phase II) [ Time Frame: 3 months ]
    Proportion of patients with deterioration defined as a drop from the HVLT-IR baseline test score that is greater than or equal to the reliable change index (RCI).

Secondary Outcome Measures:
  • Rate of immediate recall memory deterioration at 6 and 12 months [ Time Frame: 12 months ]
    Proportion of patients with deterioration, defined as a drop from the HVLT-IR baseline test score that is greater than or equal to the reliable change index (RCI).

  • Rate of delayed recall memory deterioration at 3, 6 and 12 months [ Time Frame: 12 months ]
    The percentage of patients with a decrease in HVLT-DR test score compared to baseline.

  • Incidence of brain metastases [ Time Frame: 12 months ]
    1-year rate of brain metastases together with 95% confidence interval will be calculated based on Kaplan-Meier curve.

  • Overall survival [ Time Frame: 12 months ]
    Median and 1-year rate of overall survival together with 95% confidence interval will be calculated based on Kaplan-Meier curve.

  • Changes in quality-of-life following PCI [ Time Frame: 12 months ]
    Assessed by comparing questionnaire test scores to baseline; European Organization for Research and Treatment of Cancer (EORTC) QLQ30 (global health/QOL, cognitive functioning, and fatigue scales) and BN20 (future uncertainty and communications deficit scales)

  • Change in hippocampal morphology following lithium + PCI [ Time Frame: 12 months ]
    Hippocampal volume, surface area, and length will be measured using a standardized imaging protocol (magnetization prepared rapid acquisition gradient echo; MPRAGE)

  • Incidence of adverse events [ Time Frame: 30 days after completion of therapy ]
    Adverse events will be tabulated by type and grade using NCI CTCAE v 4.

  • Feasibility of performing serial neurocognitive testing and quality of life exams in patients wit [ Time Frame: 12 months ]
    Defined as at least 4 of 6 patients successfully completing pre-treatment and 3 month post-treatment testing

Enrollment: 19
Actual Study Start Date: April 26, 2012
Study Completion Date: June 5, 2017
Primary Completion Date: September 12, 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Arm 1

Lithium carbonate 300 mg PO BID for 7 days prior to the start of prophylactic cranial irradiation (PCI) and will be continued during PCI.

PCI will be given at 2.5 Gy per fraction, 5 days per week, for 2 weeks to a total dose of 25 Gy, starting on Day 8 after 7 days of lithium.
