Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with a confirmed diagnosis of multiple myeloma or plasma cell leukemia who are fit for autologous stem cell transplant.

Probably not a fit

Patients who are not undergoing autologous stem cell transplant or those with contraindications to budesonide may not benefit from this study.

What this trial studies

This phase 2 trial investigates the impact of budesonide on the incidence of grade 2 or higher diarrhea in patients with multiple myeloma undergoing autologous stem cell transplant. The study begins with a safety run-in involving 20 patients to monitor for any safety signals related to engraftment and infection rates. If no safety concerns arise, the trial will proceed to a randomized phase where 100 patients will be split into two groups, receiving either budesonide or a placebo. Patient-reported outcomes will be collected to assess the severity and frequency of toxicities experienced during treatment.

Why it matters

Potential benefit: If successful, this study could reduce the incidence of severe diarrhea in multiple myeloma patients undergoing stem cell transplant, improving their overall treatment experience.

How similar studies have gone: While this approach is novel in the context of multiple myeloma and stem cell transplant, similar studies have shown promise in managing treatment-related toxicities in other cancer populations.

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.

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:

    * 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.
