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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 study tests whether a new combination of drugs—belantamab mafodotin plus bortezomib and dexamethasone—works better than a standard combination (daratumumab plus bortezomib and dexamethasone) for people in Japan with multiple myeloma that has come back or stopped responding to treatment. About 24 participants will be randomly assigned to one of the two combos. The main goal is to see how long the cancer stays under control.

What this could mean

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

Active substance
belantamab mafodotin (a targeted antibody-drug conjugate) combined with bortezomib and dexamethasone
What this could lead to
If this works, it could offer a new treatment option for people with multiple myeloma that has come back or stopped responding to earlier therapy.
What could go wrong
This is a small, early-phase study in Japan only, so results may not apply broadly. The experimental combo may not prove better than the standard daratumumab combo, and side effects like eye problems are possible.

Inclusion Criteria: * Confirmed diagnosis of multiple myeloma as defined by the International Myeloma Working Group (IMWG) criteria. * Previously treated with at least 1 prior line of multiple myeloma (MM) therapy and must have documented disease progression during or after their most recent therapy. * Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2. * Must have at least 1 aspect of measurable disease, defined as one of the following; 1. Urine M-protein excretion \>=200 mg per 24-hour, or 2. Serum M-protein concentration \>=0.5 grams per deciliter (g/dL), or 3. Serum free light chain (FLC) assay: involved FLC level \>=10 mg per dL (\>=100 mg per liter) and an abnormal serum free light chain ratio (\<0.26 or \>1.65). * All prior treatment-related toxicities (defined by National Cancer Institute Common Toxicity Criteria for Adverse Events \[NCI-CTCAE\] version 5.0) must be \<=Grade 1 at the time of enrollment, except for alopecia. * Adequate organ function Exclusion Criteria: * Intolerant to daratumumab. * Refractory to daratumumab or any other anti-CD38 therapy (defined as progressive disease during treatment with anti-CD38 therapy, or within 60 days of completing that treatment). * Intolerant to bortezomib, or refractory to bortezomib (defined as progressive disease during treatment with a bortezomib-containing regimen of 1.3 mg/m\^2 twice weekly, or within 60 days of completing that treatment). Note: participants with progressive disease during treatment with a weekly bortezomib regimen are allowed. * Ongoing Grade 2 or higher peripheral neuropathy or neuropathic pain. * Prior treatment with anti-B-cell maturation antigen (anti-BCMA) therapy. * Prior allogenic stem cell transplant. * Any serious and/or unstable pre-existing medical, psychiatric disorder or other conditions, including renal, liver, cardiovascular, or certain prior malignancies. * Corneal epithelial disease
