View original scientific description
A randomized placebo controlled, phase 2 study of budesonide in subjects with multiple myeloma undergoing autologous stem cell transplant (ACST). The study includes a run-in period with 20 patients.
Interventions
DRUG
Budesonide EC
Subjects will take 3mg of Budesonide or placebo. Dosing will begin on day prior to cell infusion and continue until Day 14 post transplant. Budesonide or placebo will be in capsule formulation. Budesonide or Placebo will be administered orally three times daily (every 8 hours ± 1 hours) with or without food.
DRUG
Placebo
Subjects will take 3mg of Budesonide or placebo. Dosing will begin on day prior to cell infusion and continue until Day 14 post transplant. Budesonide or placebo will be in capsule formulation. Budesonide or Placebo will be administered orally three times daily (every 8 hours ± 1 hours) with or without food.
Primary outcome measures
Proportion of patients with delayed engraftment (engraftment after day 18) and severe infection related complications (≥ Grade 4 NCI CTCAE v5).
Time frame: 18 days
impact of budesonide prophylaxis on transplant related outcomes in patients with multiple myeloma undergoing ASCT
incidence of Grade 2 or higher diarrhea from the time of ASCT until day 14 post ASCT as measured by NCI Common-Terminology Criteria (CTCAE).
Time frame: 14 days
impact of budesonide prophylaxis plus standard of care (SOC) versus standard of care (SOC) alone on the incidence of ≥ Grade 2 diarrhea (NCI CTCAE v5) in multiple myeloma patients receiving high-dose melphalan in preparation for ASCT
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Subject aged ≥ 18 years.
- History of histologically confirmed multiple myeloma and/or Plasma Cell Leukemia diagnosis undergoing ASCT who are determined to be fit by the investigator to undergo ASCT with melphalan 200 mg/m2 or melphalan 140 mg/m2 as conditioning.
- Able to provide informed consent and willing to sign an approved consent form that conforms to federal and institutional guidelines.
- Adequate organ function as defined as: --Hepatic:
- Total Bilirubin ≤ 2 x institutional upper limit of normal (ULN).
- AST(SGOT)/ALT(SGPT) ≤ 5 × institutional ULN
- For female subjects who have not undergone surgical sterilization: Negative pregnancy test or evidence of post-menopausal status. The post-menopausal status will be defined as having been amenorrheic for 12 months without an alternative medical cause or having undergone surgical sterilization (bilateral oophorectomy or hysterectomy). The following age-specific requirements apply:
- Women \< 50 years of age:
- Amenorrheic for ≥ 12 months following cessation of exogenous hormonal treatments; and
- Luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution; or
- Underwent surgical sterilization (bilateral oophorectomy or hysterectomy).
- Women ≥ 50 years of age:
- Amenorrheic for 12 months or more following cessation of all exogenous hormonal treatments; or
- Had radiation-induced menopause with last menses \>1 year ago; or
- Had chemotherapy-induced menopause with last menses \>1 year ago; or
- Underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy, or hysterectomy). Inclusion Criteria required for Patients Enrolling in Safety Run-In Cohort only: -Patient must have at least 2.5 x 106 CD34 cells in reserve for use if engraftment is delayed
Exclusion criteria
- Ongoing or current use of oral budesonide at the time of enrollment.
- Receiving other investigational agents, unless deemed acceptable after consultation with the PI
- Subjects with moderate or severe pre-existing hepatic impairment as classified according to the Child-Pugh system.
- Prior history or current diagnosis of inflammatory bowel disease, microscopic colitis at baseline.
- Prior history of receiving an allogenic stem cell transplant
- Medical, psychiatric, cognitive, or other conditions that may compromise the subject's ability to understand the subject information, give informed consent, comply with the study protocol or complete the study.
- Known prior severe hypersensitivity to melphalan or budesonide or any component in their formulations or compounds of similar composition (NCI CTCAE v5.0 Grade ≥ 3).
- Subjects taking prohibited medications as described in Section 6.6.1. A washout period of prohibited medications for a period of at least five half-lives or 14 days (whichever is shorter) should occur before the start of treatment.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
