Cholecalciferol in Improving Survival in Patients With Newly Diagnosed Cancer With Vitamin D Insufficiency


  • Study type

  • Study phase

  • Study IDs

  • Describes the nature of a clinical study. Types include:

    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
    • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
  • During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study

This partially randomized clinical trial studies cholecalciferol in improving survival in patients with newly diagnosed cancer with vitamin D insufficiency. Vitamin D replacement may improve tumor response and survival and delay time to treatment in patients with cancer who are vitamin D insufficient.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.

Inclusion Criteria:

Newly diagnosed aggressive lymphoma or CLL/small lymphocytic lymphoma (SLL) that meets disease specific criteria below:

  • Study 1 - Aggressive lymphoma
    • Newly diagnosed de-novo DLBCL or primary mediastinal B-cell lymphoma that will be treated with an anthracycline-containing regimen (rituximab-cyclophosphamide, doxorubicin hydrochloride, prednisone [R-CHOP] or equivalent); patients with composite lymphomas can also be enrolled as long as they have large cell component and will be treated with an anthracycline; in addition, patients with "B cell lymphoma, unclassifiable, with features intermediate between diffuse large B cell lymphoma and Burkitt lymphoma" or post-transplant DLBCL are also eligible as long as they meet other criteria; patients with typical Burkitt lymphoma are not eligible
      • NOTE: patients can be enrolled up through day 1 of cycle 3 of therapy; the patient is permitted to participate in any other therapeutic therapy for their disease as long as it does not concern vitamin D; patients can begin their chemotherapy while awaiting vitamin D results and treatment arm assignment or
    • Newly diagnosed untreated peripheral T-cell non-Hodgkin lymphoma (NHL) that will be treated with chemotherapy; NOTE: patients can be enrolled up through day 1 of cycle 3 of therapy; this includes the following disease types:
      • Peripheral T cell lymphoma, unspecified
      • Anaplastic large cell lymphoma (T and null cell type)
      • Extranodal NK/T-cell lymphoma, nasal type
      • Enteropathy-type T-cell lymphoma
      • Hepatosplenic T-cell lymphoma
      • Subcutaneous panniculitis-like T-cell lymphoma
      • Angioimmunoblastic T-cell lymphoma
      • Anaplastic large cell lymphoma - primary cutaneous type and
    • Willing to provide tissue for correlative research purposes
  • Study 2 - CLL/SLL
    • Newly diagnosed (< 12 months from pre-registration on this study) CLL according to the National Cancer Institute (NCI) criteria or SLL according to the World Health Organization (WHO) criteria; this includes previous documentation of:
      • Biopsy-proven small lymphocytic lymphoma
      • Diagnosis of CLL according to NCI working group criteria as evidenced by all of the following:
        • Peripheral blood lymphocyte count of > 5,000/mm^3; if present, prolymphocytes should be < 55%
        • Immunophenotyping consistent with CLL defined as:
          • The predominant population of lymphocytes share both B-cell antigens (cluster of differentiation [CD]19, CD20, or CD23) as well as CD5 in the absence of other pan-T-cell markers (CD3, CD2, etc.)
          • Dim surface immunoglobulin expression
          • Restricted surface kappa or lambda light chain expression
        • Before diagnosing CLL or SLL, mantle cell lymphoma must be excluded by demonstrating a negative fluorescent in situ hybridization (FISH) analysis for t(11;14) (immunoglobulin H [IgH]/cyclin D 1 [CCND1]) on peripheral blood or tissue biopsy or negative immunohistochemical stains for cyclin D1 on involved tissue biopsy
    • Rai stage 0 or 1
    • Previously untreated
    • Asymptomatic with the plan for observation
    • Life expectancy of at least 24 months
    • Willing to provide tissue for correlative research purposes
    • Willing to be randomized to placebo for one year
  • Both Studies:
    • Capable of swallowing intact study medication capsules
    • Serum calcium < 11 mg/dL; note: patients with hypercalcemia can be enrolled after the calcium is corrected with standard of care treatments
    • Willing to return to enrolling institution for follow-up (during the active monitoring phase of the study)
      • Note: During the Active Monitoring Phase of a study (i.e., active treatment and observation), participants must be willing to return to the consenting institution for follow-up
    • Willing to provide blood samples for correlative research purposes
    • Vitamin D level (25 hydroxy D2 + hydroxyl D3) confirmed by central laboratory review
