Ultra-high Dose Vitamin D for HSCT

May 17, 2024 updated by: Etan Orgel, Children's Hospital Los Angeles

Pilot Study of Transplant-related Events in Patients Receiving Ultra-high-dose Vitamin D Supplementation

This is a pilot study to investigate the effects of achieving adequate vitamin D levels via ultra-high-dose vitamin D supplementation given prior to hematopoietic stem cell transplant on transplant-related complications and inflammatory biomarkers.

Study Overview

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Up to 70% of patients have vitamin D deficiency prior to hematopoietic stem cell transplant (HSCT). Patients with sufficient Vitamin D levels (>50nm/L) prior to allogeneic transplant have significantly better overall survival (OS) and lower rates of rejection and relapse. Vitamin D inhibits Th1 and augments Th2 cell development. Patients who receive vitamin D supplementation during allogeneic transplant have less inflammatory-mediated processes such as chronic graft versus host disease (GVHD) and lower levels of naïve CD8+ cells and CD40 ligand. Multiple studies have raised concern regarding the adequacy of standard and high-dose vitamin D dosing for vitamin D deficiency. A single oral ultra-high dose of Vitamin D given prior to HSCT has been shown to be a safe and well tolerated method of sustaining therapeutic Vitamin D levels for 6-19 weeks.

This is a pilot study to investigate the dynamic changes in inflammatory biomarkers following ultra-high-dose vitamin D supplementation. The study population is patients with total vitamin D level </=50ng/mL prior to HSCT.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

1 second to 25 years (Child, Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Patients who are preparing for HSCT
  • If a patient is receiving an autologous transplant, enrollment must occur prior to first transplant in the case that the patient is planned for multiple transplants

Exclusion Criteria:

  • Uncorrected hypocalcemia or hypophosphatemia
  • Patients in the ICU or on renal replacement therapy
  • Patients who have had an allogeneic transplant within the past 12 months prior to enrollment

Enrolled patients with 25OHD level ≤50 ng/mL continue on study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Vitamin D (Cholecalciferol)
All subjects will be enrolled to this arm. A single dose of ultra-high-dose vitamin D will be given.
Drug: Cholecalciferol
A single dose of ultra-high-dose vitamin D (cholecalciferol) will be given prior to hematopoietic stem cell transplant. Research labs including inflammatory biomarker panels will be obtained prior to and after the dose is given.
Other Names:
  • vitamin D

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Incidence of graft-versus-host disease, veno-occlusive disease, and thrombotic microangiopathy
Time Frame: 100 days after transplant
Graft-versus-host disease, veno-occlusive disease, and thrombotic microangiopathy
100 days after transplant
Vitamin D sufficiency following Stoss dosing
Time Frame: prior to transplant
Vitamin D sufficiency following Stoss dosing prior to tranpslantation
prior to transplant

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
