What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This phase 3 trial tests whether a less intense version of a standard chemotherapy regimen can reduce side effects by half while still controlling low-risk multiple myeloma in adults 65 and under. Participants receive a combination of drugs, a stem cell transplant, and three years of maintenance therapy. The study originally compared two regimens, but the milder arm has been closed, and all new participants now receive the standard treatment.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
combination chemotherapy (melphalan, bortezomib, thalidomide, dexamethasone, cisplatin, doxorubicin, cyclophosphamide, etoposide) followed by stem cell transplant and maintenance therapy
What this could lead to
If successful, this could offer a less toxic treatment option for low-risk multiple myeloma that still controls the disease effectively.
What could go wrong
This is an early-stage comparison of two intensive regimens; the reduced-toxicity arm has already been closed. The trial is not designed to cure, and long-term side effects from chemotherapy and transplant remain significant.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients must have newly diagnosed active MM requiring treatment. Patients with a previous history of smoldering myeloma will be eligible if there is evidence of progressive disease requiring chemotherapy. * Patients must be either untreated or have not had more than one cycle of systemic MM therapy, excluding bisphosphonates and localized radiation. * Participants must have low-risk disease, as defined by any of the following: * GEP risk score of \< 0.66 * lack of GEP-defined TP53 deletion (Affymetrix signal \<727) * No metaphase based abnormalities of 1q or 1p * LDH \<360 U/L Rule out hemolysis, infection, and contact PI for Clarification * Zubrod ≤ 2, unless solely due to symptoms of MM-related bone disease. * Patients must be at least 18 years of age and not older than 75 years of age at the time of registration. * Participants must have preserved renal function as defined by a serum creatinine level of \< 3 mg/dL. * Participants must have an ejection fraction by ECHO or MUGA ≥ 40% * Patients must have adequate pulmonary function studies \> 50% of predicted on mechanical aspects (FEV1, FVC, etc) and diffusion capacity (DLCO) \> 50% of predicted. If the patient is unable to complete pulmonary function tests due to MM related pain or condition, exception may be granted if the principal investigator documents that the patient is a candidate for high dose therapy. * Patients must have signed an IRB-approved informed consent indicating their understanding of the proposed treatment and understanding that the protocol has been approved by the IRB. Exclusion Criteria: * High risk disease defined by high-risk gene array features as determined by any of the following: * GEP risk score of ≥ 0.66 or * Presence of GEP-defined TP53 deletion, or * Presence of abnormalities of chromosome 1 (amp1q, del 1p). * Poorly controlled hypertension, diabetes mellitus, or other serious medical illness or psychiatric illness that could potentially interfere with the completion of treatment according to this protocol. * Platelet count \< 30 x 109/L, unless myeloma-related. * Grade \> 2 peripheral neuropathy. * Hypersensitivity to bortezomib, boron, or mannitol. * Recent (\< 6 months) myocardial infarction, unstable angina, difficult to control congestive heart failure, uncontrolled hypertension, or difficult to control cardiac arrhythmias. * Evidence of chronic obstructive or chronic restrictive pulmonary disease. * Patients must not have light chain deposition disease or creatinine \> 3 mg/dl * No prior malignancy is allowed except for adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, or other cancer for which the patient has been disease free for at least three years. Prior malignancy is acceptable provided there has been no evidence of disease within the three-year interval or if the malignancy is considered much less life threatening than the myeloma. * Pregnant or nursing women may not participate. Women of childbearing potential must have a negative pregnancy documented within one week of registration. Women/men of reproductive potential may not participate unless they have agreed to use an effective contraceptive method.
