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

The trial is a randomized, comparative, double-blind trial comparing the efficacy and safety of pentaisomaltose (PentaHibe®, Pharmacosmos A/S, Holbæk; termed PIM in the following) and dimethyl sulphoxide (DMSO), when used for preservation of harvested hematopoietic stem cells. Approximately 150 subjects with a diagnosis of multiple myeloma or malignant lymphoma (a minimum of 30 % of each diagnosis and an equal distribution in each preservation group) and undergoing autologous stem cell transplantation (ASCT) will be included.

The subjects will be randomized 1:1 to receive ASCT preserved in the following cryo-protective agent (CPA):

  • A: PIM 16 %
  • B: DMSO 10 %

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Men or women ≥ 18 years
  • Multiple myeloma or malignant lymphoma diagnosis in which ASCT is indicated according to the standard procedures at the hospital
  • Willing to be hospitalized for minimum 24 hours after the ASCT
  • Willingness to participate and signing the ICF

Exclusion Criteria:

  • Multiple myeloma or lymphoma invasion of the central nervous system
  • Previous treatment with ASCT
  • Severe infection
  • Unsuitable for apheresis
  • Unable to provide ≥3 bags with a cell concentration ≥2.0×106 CD34+ cells/kg bodyweight per bag during apheresis
  • Pregnant or nursing women. To avoid pregnancy, women of childbearing potential have to use adequate contraception (e.g., intrauterine devices, hormonal contraceptives, or double barrier method) during the whole trial period and up to 1 year after the last ASCT
  • Men, even if surgically sterilized, (i.e., status post vasectomy), who do not agree to practice effective barrier contraception during the entire trial period and through 6 months after the last ASCT, or agrees to completely abstain from heterosexual intercourse
  • Any other medical condition which, in the opinion of the Investigator, will put the subject's disease management at risk or may result in the subject being unable to comply with the trial requirements

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.
Other: A: Pentaisomaltose 16 %
Pentaisomaltose 40 % sterile solution; 40 mL will be transferred to a total volume of 100 mL, so the final concentration is 16 %.
Other: Pentaisomaltose
Each subject will receive 1 or 2 bags with cryopreserved cells according to randomization group.
Active Comparator: B: DMSO 10 %

Comparator:

DMSO 99.9 % sterile solution; 10 mL will be transferred to a total volume of 100 mL, so the final concentration is 10 %.
Other: Pentaisomaltose
Each subject will receive 1 or 2 bags with cryopreserved cells according to randomization group.

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
Engraftment of hematopoietic stem cells
Time Frame: 19 days
Incidence of subjects with engraftment of hematopoietic stem cells, defined as 2 consecutive measurements with a neutrophil concentration >0.5×109/L within the first 19 days after ASCT
19 days
Incidence of subjects with AEs of special interest (limited)
Time Frame: 24 hours after ASCT
Incidence of subjects with AEs of special interest (limited) occurring within 24 hours after ASCT: headache, nausea, vomiting, bradycardia, or unpleasant odor
24 hours after ASCT

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.
Outcome Measure
Measure Description
Time Frame
Incidence of subjects with AEs of special interest (limited)
Time Frame: 19 days
Incidence of subjects with AEs of special interest (limited): headache, nausea, vomiting, bradycardia, or unpleasant odor

Time to engraftment of neutrophil cells
Time Frame: 19 days
• Time to engraftment of neutrophil cells, defined as 2 consecutive measurements with a neutrophil concentration >0.5×109/L within the first 19 days after ASCT
