About this study

This is a research study to find out if a drug called belantamab mafodotin in combination with dexamethasone, a steroid, can be safely and effectively given in the community setting. Belantamab mafodotin (BLENREP) was approved in the US in August 2020 under an FDA program called accelerated approval. In November 2022, belantamab mafodotin was removed from the market because a study to further confirm its activity in relapsed/refractory multiple myeloma did not deliver a supporting result. However, this confirmatory study demonstrated that some patients may still benefit from treatment with belantamab mafodotin, and that this benefit can be long lasting. Belantamab mafodotin is often given at large academic medical centers every 3 weeks. This study will assess whether it is possible to administer belantamab in the community setting every 6 weeks. It is unknown if administering belantamab every 6 weeks versus every 3 weeks will result in improved safety and/or reduced efficacy.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Assess the feasibility of providing Belantamab mafodotin in a heavily pretreated, rural population of patients with multiple myeloma receiving this study regimen every 6 weeks instead of every 3-week cycles.

    Belantamab mafodotin will be evaluated in participants with RRMM (relapsed/refractory multiple myeloma) in the community as assessed through the rate of 'unacceptable toxicity' and response rate as defined in Table 7 through all cycles

    Measured: From registration until stopped early due to excess unacceptable toxicity and/or lack of efficacy. Subjects followed for 2 years from end of treatment

Secondary outcomes (10)

  1. Describe the efficacy of Belantamab mafodotin specifically in the elderly frail sub-population defined by the IMWG (International Myeloma Working Group) Geriatric Assessment

    The score system (range 0-5), based on age, comorbidities, cognitive and physical conditions, developed by Palumbo A. et al1, identifies 3 groups of patients:

    • Fit (score=0)
    • Intermediate-Fitness (Score=1)
    • Frail (Score ≥2)

    Measured: From registration until stopped early due to excess unacceptable toxicity and/or lack of efficacy. Subjects followed for 2 years from end of treatment

  2. Overall Response Rate (ORR) (Full Analysis Population)

    ORR was determined according to the 2016 international myeloma working group (IMWG) response criteria by IRC. ORR was calculated as the percentage of participants with a confirmed partial response (PR) or better (that is [i.e.], PR, very good partial response [VGPR], complete response [CR] and stringent complete response [sCR]). Confidence intervals were based on the exact method.

    Measured: Up to 48 weeks

  3. Clinical Benefit Rate (CBR) by Investigator Assessment (Full Analysis Population)

    CBR was determined by the investigator according to the 2016 IMWG response criteria. CBR was calculated as the percentage of participants with a confirmed minimal response (MR) or better (i.e., MR, PR, VGPR, CR and sCR). Confidence intervals were based on the exact method.

    Measured: Up to 48 weeks

  4. Duration of Response (DoR) by Investigator Assessment (Full Analysis Population)

    DoR is defined as the time from first documented evidence of PR or better until the earliest date of documented disease progression (PD) per IMWG response criteria; or death due to PD among participants who achieved an overall response, i.e., confirmed PR or better. DOR based on responses assessed by investigator is presented. Median and inter-quartile range (first quartile and third quartile) of DOR are presented

    Measured: Up to 48 weeks

  5. Time to Response by Investigator Assessment (Full Analysis Population)

    Time to response is defined as the time between the date of randomization and the first documented evidence of response (PR or better), among participants who achieve a response (i.e., confirmed PR or better). Time to response based on responses assessed by investigator is presented. Median and inter-quartile range (first quartile and third quartile) of time to response are presented.

    Measured: Up to 48 weeks

  6. Progression Free Survival by Investigator Assessment

    Progression free survival is defined as the time from enrollment until the earliest date of documented PD per IMWG, or death due to any cause. Progression free survival based on responses assessed by investigator is presented. Median and inter-quartile range (first quartile and third quartile) of progression free survival are presented.

    Measured: Up to 48 weeks

  7. Time to Progression by Investigator Assessment

    Time to progression is defined as the time from enrollment until the earliest date of documented PD per IMWG, or death due to PD. Time to Progression based on responses assessed by investigator is presented. Median and inter-quartile range (first quartile and third quartile) of time to progression are presented.

    Measured: Up to 48 weeks

  8. Overall Survival

    Overall survival is defined as the time from randomization until death due to any cause. Median and inter-quartile range (first quartile and third quartile) of overall survival are presented.

    Measured: Up to 48 weeks

  9. Assess the safety of belantamab mafodotin in the elderly frail population for unacceptable toxicity Grade 3 or higher

    The safety profile of belantamab mafodotin will be evaluated in participants with RRMM in the community as defined by the standard clinical and laboratory tests (hematology and chemistry, physical examination, vital sign measurements, and diagnostic tests) through the collection of adverse events (AEs) and serious adverse events (SAEs).

    Measured: All adverse events whether serious or non-serious, will be reported from the start of treatment until 70 days after the last dose of study treatment, until the subject withdraws consent for study participation, or until the subject starts new treatment

  10. Corneal events will be graded according to the KVA Scale

    All adverse events whether serious or non-serious, will be reported

    Measured: From the start of treatment until 70 days after the last dose of study treatment, until the subject withdraws consent for study participation, or until the subject starts subsequent anticancer therapy, whichever occurs first.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Belantamab mafodotin in people with Relapsed/Refractory Multiple Myeloma, run by Cristiana Costa Chase, DO at 5 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 18 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 28 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Assess the feasibility of providing Belantamab mafodotin in a heavily pretreated, rural population of patients with multiple myeloma receiving this study regimen every 6 weeks instead of every 3-week cycles. (time frame: From registration until stopped early due to excess unacceptable toxicity and/or lack of efficacy. Subjects followed for 2 years from end of treatment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05874193, which also lists 14 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Sep 2026.
